Stockport's Loft Conversion Specialists

A loft conversion is the smartest, most cost-effective square footage you will ever add to your home. The space is already there, sitting right above your ceiling, transforming it into a master bedroom with an en-suite, a quiet home office, or a spacious guest room gives you the space you need at a fraction of the cost of a ground-floor extension.

We build dormer, Velux, and hip-to-gable loft conversions for homeowners across Stockport, Bramhall, Cheadle Hulme, Marple, Hazel Grove, Poynton and Wilmslow.

Why Choose a Roofing Specialist Over a General Builder?

Around 80% of a loft conversion is roofing work. Cutting the opening, framing the dormer, laying the EPDM flat roof on the dormer cheek, fitting the lead flashings, and matching the tiles or slate on the rest of the roof, general builders typically subcontract all of this out to whoever is available that week.

We don't. We handle it entirely in-house with the same expert crew that has been working on Stockport roofs for over twenty years. One team, one point of accountability, and no finger-pointing between trades when something needs putting right.

Designed Around Your Roof

Every home is different, and we never use a one-size-fits-all template. Whether your property is best suited for a simple Velux roof window conversion, a spacious rear dormer, or a hip-to-gable extension, we design the build around exactly what your roof structure can take. Pitch, span, headroom, and party-wall position all factor in.

If a roof survey reveals issues with the existing structure (sagging rafters, perished underfelt, or failing timbers), we'll flag them before quoting so the loft conversion isn't built on a roof that needs replacing in five years.*

* A full independent roofing survey is not required to proceed with a loft conversion, our standard pre-quote inspection covers everything needed to design and price the build.

What our customers say

  • ★★★★★

    “Dan went up into the loft as I wanted to use it for storage. He strengthened the support by building a platform, put down new boarding and added more insulation, as the original floor was not strong enough for what I was storing. We discussed a window and I decided to go for a Velux, so glad I did. Dan has great attention to detail and was approachable, knowledgeable and patient throughout. I am very happy with the job done by Daniel Scott Roofing and very pleased to recommend Dan and his team.”

    “I used Daniel Scott to re-roof a second floor large dormer. Dan came round himself to provide a detailed quote and was very professional. He also attached a tarpaulin to cover the leaking roof until they could come and do the work. They came earlier than promised and did an excellent job. Photos were provided to me and a guarantee. A gutter and downpipe, plus insulation, were also included. I am very pleased with the work completed and would recommend the company to anyone.”

Loft Conversion Types We Build

The right conversion depends on your roof, its pitch, its shape, and how much usable ridge height you have above the existing ceiling joists. Below are the four types we build most often across Stockport and East Cheshire.

  • Velux & Rooflight Loft Conversions

    • 4–6 weeks build
    • From £18,000–£28,000
    • No planning needed
    • Roofline unchanged
    A Velux conversion (sometimes called a rooflight conversion) is the simplest and lowest-cost type of loft conversion. We don't change the external shape of the roof. We reinforce the floor, insulate to current Building Regs, and install Velux roof windows for natural light. From the street, your house looks identical.

    What's involved

    • Structural floor reinforcement with new joists or steel sections
    • Full warm-roof insulation between and over the rafters (Part L compliant)
    • Velux or equivalent rooflights with integrated lead flashings around each unit
    • Regulation fixed staircase and fire doors on the floor below where required
    • Electrics, lighting, plasterboard, and plaster finish

    No planning permission is needed in most cases, the work falls under Permitted Development. Build time is typically 4–6 weeks, with costs from around £18,000–£28,000 depending on size and finish.

    Best suited to

    • Steep-pitched roofs with at least 2.4m of existing ridge height
    • Edwardian and early 1930s semi-detached homes where the original 45° pitch already gives the headroom
    • Bungalows across Hazel Grove, Cheadle Hulme and Marple with a large loft footprint
    • Homeowners after a master bedroom, home office, or guest room without altering the roofline

  • Dormer Loft Conversions

    • 6–10 weeks build
    • From £30,000–£60,000
    • Permitted Development*
    • Full ceiling height
    A rear dormer is the workhorse of Stockport loft conversions and the type we build most often. A flat-roof box structure is added to the back slope of the roof, creating vertical walls and full ceiling height across the new floor, turning an unusable angled space into a proper master suite, two bedrooms, or a family room with en-suite.

    What's involved

    • Structural opening cut into the rear roof slope, with a new steel or timber portal frame
    • Box-frame dormer construction, with hanging tiles, slate, or render to the cheeks to match the original roof
    • High-performance EPDM rubber flat roof on top of the dormer, with a 50-year membrane fully laid by our roofing team
    • Lead flashings at every upstand where the dormer meets the existing roof (this is where cheap conversions fail in 5–10 years)
    • Full warm-roof insulation, regulation staircase, fire doors, electrics, and plasterboard

    Most rear dormers fall under Permitted Development if kept within 50m³ on a semi-detached property. Build time is 6–10 weeks, with costs from £30,000–£60,000 depending on size, en-suite inclusion, and finish.

    Best suited to

    • Stockport's interwar and post-war semi-detached homes across Bramhall, Cheadle Hulme, Hazel Grove, Marple, Bredbury, and Offerton
    • Properties where you want a full master bedroom with en-suite, not a single small room
    • Anyone with usable ridge height but limited floor area in the unconverted loft

  • Hip-to-Gable Loft Conversions

    • 8–11 weeks build
    • From £40,000–£60,000
    • Planning required
    • Unlocks side-of-loft space
    A hip-to-gable conversion is for properties with a hipped (sloping) side roof, common on end-of-terrace houses, 1930s semi-detached homes, and detached bungalows across Hazel Grove, Marple, Bredbury and Cheadle. The sloping side is replaced with a vertical gable wall, extending the ridge line and unlocking the side-of-loft space that was previously unusable.

    What's involved

    • Removal of the existing hipped roof timbers and tiles
    • New gable wall built up in matching brickwork, or rendered to match the original
    • Ridge extension and new rafters across the enlarged roof space
    • Tile or slate matching across the new section to blend with the existing roof
    • Often combined with a rear dormer to maximise floor area and headroom

    Hip-to-gable usually requires planning permission rather than falling under Permitted Development, particularly on a side elevation visible from a public highway. We handle the application with Stockport MBC or Cheshire East Council on your behalf. Build time is 8–11 weeks; costs typically £40,000–£60,000 alone, or £50,000–£70,000 when combined with a rear dormer.

    Best suited to

    • End-of-terrace properties where one side has a sloping roof
    • Semi-detached homes with hipped side roofs (common in 1930s housing stock across Bramhall and Hazel Grove)
    • Detached bungalows where the entire loft footprint can be opened up
    • Homes where a straight Velux or rear dormer alone would lose too much usable space to the slopes

  • L-Shaped Dormer Conversions

    • 9–12 weeks build
    • From £60,000–£80,000
    • Two bedrooms + bathroom
    • Victorian / Edwardian terraces
    An L-shaped dormer is the gold standard for Victorian and Edwardian terraces, particularly the long, narrow terraces with a rear outrigger you find across Edgeley, Heaton Moor, Reddish and Heaton Chapel. Two dormers are built, one on the main rear roof, one on the outrigger roof, meeting at right angles to form an L-shape. The result is enough usable floor space for two bedrooms and a bathroom on the new floor.

    What's involved

    • Full structural opening across both the main rear roof and the outrigger
    • Two box dormers built at right angles to each other, with a structural valley between them
    • Matching tile or slate cheeks (or hanging tiles where the conservation context calls for it)
    • EPDM flat roof across both dormer tops, fully laid by our roofing team
    • Lead flashings at every junction, as the L-junction is technically demanding and where lesser conversions leak
    • Full warm-roof insulation, regulation staircase, fire doors, two new bedrooms, and a bathroom

    Build time is 9–12 weeks, with costs from £60,000–£80,000 depending on internal layout, en-suite inclusion, and conservation area requirements, parts of Heaton Moor and The Heatons fall within designated conservation areas, which restricts external materials.

    Best suited to

    • Victorian and Edwardian terraces with rear outriggers (most pre-1920 terraces in Stockport)
    • Households needing two bedrooms rather than one, typically growing families
    • Properties where a single rear dormer wouldn't deliver enough floor area to justify the project

How Much Does a Loft Conversion Cost in Stockport?

Most builders quoting loft conversions don't publish prices. We do, for two reasons. The ranges below are based on jobs actually completed across Stockport and East Cheshire, not industry averages or headline-grabbing low numbers. And if your budget is £25,000 and the project you want costs £55,000, it's better for both of us to know that before we book a survey.

What drives the variation within each range

  • Ridge height If existing height is below 2.2m, the project needs a roof lift before the conversion can begin, see our new roofs page for indicative costs on that work.
  • Roof structure Pre-1965 cut roofs convert straightforwardly. Modern trussed rafters need structural alterations to remove the webs, full structural details are covered on our new roofs page.
  • Stair position Where the new staircase lands below dictates whether it's a clean drop-in or whether existing rooms need reconfiguring.
  • Finish level A standard build gives a usable, well-finished room. A high-spec build with bespoke joinery, premium tiling, and integrated AV will sit at the upper end of the published range.
  • Conservation area requirements Restricted external materials (handmade tiles, lead detailing visible from a public highway) add cost. Most relevant in Knutsford, Wilmslow, Alderley Edge, and parts of The Heatons and Heaton Moor.
  • Scaffold access Terraced properties with rear-only access cost more to scaffold than detached properties with all-round access.
Typical loft conversion costs in 2026
Conversion type Typical range Build time
Velux / Rooflight £18,000 – £28,000 4–6 weeks
Rear Dormer (single bedroom) £30,000 – £42,000 6–8 weeks
Rear Dormer + En-suite £50,000 – £60,000 8–10 weeks
Hip-to-Gable £40,000 – £60,000 8–11 weeks
Hip-to-Gable + Rear Dormer £50,000 – £70,000 9–11 weeks
L-Shaped Dormer (Victorian terrace) £60,000 – £80,000 9–12 weeks

These ranges are published as customer guidance only and may not reflect the figure on your individual written quote. Every project is priced on its own merits, and we're happy to talk through any difference between the indicative range and your bespoke quote.

Our Installation Process

Every loft conversion we build follows the same eight-stage process, from first survey to handover certificates. No verbal estimates, no hidden trades, no surprises halfway through.

  1. Free Survey & Feasibility Assessment

    We come out, measure your loft, and tell you honestly whether the conversion you want is possible. The survey takes about an hour.

    What we check

    • Ridge height, measured floor-to-ridge to confirm you've got the 2.2m minimum
    • Roof structure, whether cut roof or trussed rafters
    • Stair landing position below and headroom over the new staircase
    • Existing roof condition, so the conversion isn't built on a roof that needs replacing in five years
    • Boiler capacity for an additional bathroom
    • Conservation area, listed building, or Article 4 status

    You get: A written feasibility note with our recommended conversion type and an indicative cost range. Free, no obligation.

  2. Design & Written Quote

    After survey we produce architect drawings and a fully itemised written quote. No verbal estimates, no costs added once work has started.

    What's specified

    • Conversion type, dimensions, and internal layout
    • Materials such as the EPDM flat roof system, insulation thickness, and Velux model
    • Build sequence and week-by-week timeline
    • VAT included on the headline number, not added at the end

    You get: Drawings + quote, valid for 90 days. Typical turnaround: 7–14 days from survey.

  3. Planning & Building Regulations Submission

    We submit all applications to Stockport MBC or Cheshire East Council on your behalf. Building Regulations approval is always required; planning depends on whether the build qualifies for Permitted Development.

    What we handle

    • Planning application where required (typical decision: 8 weeks)
    • Building Regulations submission with full structural calcs and Part L insulation specs
    • Party Wall Act notices for terraces and semi-detached properties
    • Heritage statements for conservation area properties

    You get: Copies of every submission, plus we handle all correspondence with the council. Runs 4–10 weeks, in parallel with other prep.

  4. Scaffold & Site Setup

    Day one of the build phase. Scaffold goes up around the rear (and side, for hip-to-gable conversions). Almost all of the work for the next four to six weeks happens from the scaffold side without anyone entering your house.

    What goes on

    • Full scaffold to the rear elevation
    • Weather protection ("tin lid") erected over the working area
    • Skip placed in an agreed location
    • Site protection inside any rooms that will be affected later

    You get: A printed week-by-week schedule pinned to your fridge. Time: day 1.

  5. Roof Opening & Dormer Construction

    This is where the roofing trade does the bulk of the work. The opening is cut, the structural frame goes in, the dormer is built, and the roof is sealed watertight.

    What happens

    • Roof slope opened; existing tiles or slate carefully removed and stored for reuse where matching
    • Steel beams or timber portal frame installed
    • Dormer box-frame built and insulated between studs
    • High-performance EPDM rubber flat roof laid by our roofing team, with a 50-year membrane fully bonded
    • Lead flashings dressed at every upstand and abutment
    • Tile or slate matching across the original roof and dormer cheeks

    You get: A watertight shell, externally finished. Daily life inside the house carries on as normal. Time: 2–4 weeks.

  6. Structural Floor & First Fix

    Once the roof is sealed, internal work begins. The new floor is built, services run in, and rooms framed up. Still mostly accessed via scaffold.

    What happens

    • New floor joists or steels installed, which is what gives the loft its load capacity for habitation
    • Stud walls framed for the new rooms
    • First-fix electrics, plumbing for radiators and bathroom where specified
    • Full warm-roof insulation installed between and over the rafters (Part L compliant)
    • Plasterboard and skim plaster

    You get: Visible rooms taking shape. Mostly external access still. Time: 3–4 weeks.

  7. Staircase & Connection to the House

    This is the only stage with real internal disruption, and it's brief. The new staircase is fitted, connecting the new floor to the rest of the house.

    What happens

    • Staircase opening cut into the existing ceiling
    • Regulation fixed staircase installed with 2m headroom over every step
    • Fire doors fitted to existing rooms on the floor below where required
    • Ceiling repaired, plastered, and ready to decorate
    • Dust protection sheets sealed off the staircase area from the rest of the house throughout

    You get: Internal access to the new floor. Time: about 1 week.

  8. Snag, Handover, Certificates & Guarantee

    Final walkthrough, snag list, paperwork, keys.

    What you receive

    • Building Regulations completion certificate (issued by Building Control)
    • Electrical safety certificate (NICEIC)
    • Gas Safe certificate on any new heating work
    • 10-year workmanship guarantee in writing
    • Final invoice, issued only after every snag item is signed off

Total project time: Typically 12–20 weeks from initial survey to handover, with the build phase itself running 6–12 weeks depending on conversion type. Full pricing and build times per type are in our pricing section.

Frequently asked questions

Do I need planning permission for a loft conversion in Stockport?

Most loft conversions in Stockport fall under Permitted Development and don't need planning permission, provided you stay within the volume limits,40m³ for terraces, 50m³ for semi-detached and detached houses, and the dormer doesn't extend higher than the existing ridge or past the front roof slope. Planning permission is required if you live in a conservation area (parts of The Heatons, Compstall, Marple Bridge, or sections of Cheadle and Cheadle Hulme), if your property is listed, or if the design raises the existing roofline. We handle the full application with Stockport Metropolitan Borough Council on your behalf as part of every quote.

How much does a loft conversion cost in Stockport?

A loft conversion in Stockport typically costs between £18,000 for a Velux conversion and £80,000 for a full L-shaped dormer in a Victorian terrace. The most common type, a rear dormer with en-suite, sits between £50,000 and £60,000 depending on size and finish. The biggest variables are ridge height (a roof lift adds £8,000–£15,000), en-suite plumbing run, finish level, and conservation area material requirements. Full ranges and what's included as standard are in our pricing section above.

How long does a loft conversion take to build?

A loft conversion typically takes 4–12 weeks to build, depending on the type. A Velux conversion takes 4–6 weeks, a rear dormer 6–10 weeks, a hip-to-gable 8–11 weeks, and an L-shaped dormer 9–12 weeks. That's the build phase only. Design, Building Regulations approval, and (where required) Planning Permission add 4–8 weeks before the build starts. Most Stockport projects run 12–20 weeks from initial survey to handover.

Can I live in my house during a loft conversion?

Yes, most homeowners stay in their home throughout the loft conversion. The bulk of the work is accessed from external scaffolding, not through the house, so for the first four to six weeks the disruption is mostly noise rather than internal mess. The only stage that creates real internal disruption is the staircase break-through, which usually takes place in the final two weeks of the build. We seal off work zones with dust protection, communicate the schedule week by week, and keep one team on site throughout, no rotating subcontractors traipsing through your home.

How much value will a loft conversion add to my house?

A well-finished loft conversion typically adds 15–25% to a Stockport property's value, with the strongest uplift coming from a master bedroom plus en-suite combination on the new floor. In higher-demand areas like Bramhall, Cheadle Hulme, Wilmslow and Alderley Edge, the uplift often clears the full cost of the build. Estate agent data across the SK postcodes consistently shows a properly converted three-bed becoming a four-bed delivers a higher return per pound spent than a ground-floor extension of equivalent budget.

Will my loft convert? What's the minimum head height needed?

A loft is suitable for conversion if you have at least 2.2m of height from the top of the existing ceiling joists to the underside of the ridge, a roof pitch of 30° or steeper, and a stair landing position below with 2m of headroom over every step. If your existing ridge height is below 2.2m, a roof lift is possible but adds £8,000–£15,000 to the project. Pre-1965 cut roofs convert most easily; modern trussed rafters need additional structural work to remove the internal webs. We confirm all of this at the free survey stage before quoting.

What's the difference between a Velux and a dormer loft conversion?

A Velux (or rooflight) conversion installs roof windows in your existing roofline without changing the external shape of the roof. A dormer conversion adds a box-shaped structure to the rear roof slope, creating vertical walls and full ceiling height, significantly more usable floor space. Velux is cheaper (£18,000–£28,000), faster (4–6 weeks), and rarely needs planning permission. Dormer is dearer (£30,000–£55,000), takes 6–10 weeks, and gives you a proper master suite rather than an attic-shaped room. Velux suits steep-pitched Edwardian and 1930s semi-detached homes with existing headroom; dormer suits the bulk of Stockport's interwar and post-war semi-detached homes where headroom is tight.

Do I need building regulations approval for a loft conversion?

Yes, every loft conversion in the UK requires Building Regulations approval, regardless of whether it needs planning permission. Building Regs cover structural integrity, fire safety (Part B), thermal insulation (Part L), sound insulation between floors (Part E), and the staircase specification. A loft conversion legally upgrades your property to three storeys, which triggers stricter fire safety rules, including fire doors on the floor below in most cases. We submit and manage all Building Regs applications on your behalf, and you receive a completion certificate at handover that lenders and buyers will need when you sell or remortgage.

Can I have a loft conversion in a conservation area in Knutsford, Wilmslow, or The Heatons?

Yes, but planning permission is always required in conservation areas, Permitted Development rights don't apply. In Cheshire East conservation areas (Knutsford, Wilmslow, Alderley Edge, Bollington), front-facing roofline changes are usually prohibited, but rear dormers and conservation-grade Velux windows are routinely approved. Some conservation areas carry an Article 4 Direction, which restricts even minor changes like rooflights. Listed buildings always require Listed Building Consent in addition to planning. We carry out the conservation area check at survey stage and handle the application with Cheshire East Council or Stockport MBC.

Will my existing boiler handle the new bathroom?

Adding a bathroom on a third storey requires adequate water flow rate and pressure. We assess your existing boiler at survey, combi boilers under 30kW often struggle with a third bathroom, while system boilers with a hot water cylinder usually cope without modification. This is the check general builders most often miss. If your boiler needs upgrading to handle the additional bathroom, the typical cost is £2,500–£4,500, and we factor it into the written quote before any work starts. Discovering it mid-build means delays and uncomfortable conversations about money, and that's the kind of project that gives our trade a bad name.

Can a Victorian terrace loft be converted?

Yes, Victorian and Edwardian terraces are some of the best candidates for loft conversion because of their steep roof pitch and rear outrigger. The L-shaped dormer is the most popular conversion type for terraces in Edgeley, Heaton Moor, Reddish and Heaton Chapel, delivering enough usable floor space for two bedrooms and a bathroom on the new floor. Terrace conversions trigger Party Wall Act notices to neighbours on both sides, which we draft and serve as part of the project. Some streets in Heaton Moor and The Heatons fall within designated conservation areas, which restricts external materials, usually meaning Welsh slate or matching handmade tiles rather than concrete substitutes.

What guarantee do you provide on loft conversions?

Every loft conversion we build carries a 10-year workmanship guarantee. You also receive a Building Regulations completion certificate, an electrical safety certificate (NICEIC), and Gas Safe certification on any new heating work, the legal documentation lenders, surveyors and buyers will need when you sell or remortgage. We're CORC-registered (Confederation of Roofing Contractors) and fully insured for both public and employer's liability. The 10-year cover applies to the structural roofing elements, dormer construction, EPDM flat roof, lead flashings, which is where lesser conversions fail in the 5–10 year window.
