Ealing's roofs were made for this

Ealing earned its nickname, the Queen of the Suburbs, on the strength of exactly the houses that convert best: Edwardian and Victorian terraces with steep, generous roofs around the Broadway, the Common and West Ealing, and street after street of 1930s hipped-roof semis through Greenford, Perivale and Northolt.

That is why a loft conversion in Ealing is so often the smartest move a growing family can make: the head height is usually already there, most rear dormers and hip-to-gables can proceed as permitted development, and the extra bedroom and bathroom are precisely what the area's family-house market rewards. Lower roof? A small loft conversion can still work, and the borough's bungalow streets suit a bungalow loft conversion.

We convert every type: dormer, hip-to-gable, Velux, mansard and L-shaped, with every trade in-house and one fixed price including VAT. Start with our loft conversion service or the loft cost guide for the full picture.

Planning In Ealing

Most Ealing Lofts Need No Planning Application

Loft conversions enjoy generous permitted development rights, and Ealing's housing stock uses them well. Here is the position, honestly.

40–50m³ The roof-volume allowance
most conversions
fit inside
  • 1Permitted development covers most rear dormers and hip-to-gables, as long as the extra roof volume stays within 40 cubic metres for a terraced house or 50 cubic metres for a semi-detached or detached house, the dormer is set back from the eaves, sits no higher than the ridge, and side windows are obscure-glazed.
  • 2Where it is PD, we still get you paperwork: a Lawful Development Certificate (£274) from the council, so you hold official proof for your records and any future sale.
  • 3Some Ealing streets are the exception: conservation areas and roads with Article 4 directions restrict dormer rights, and a mansard or front-facing change needs a full application (£548) anywhere. We check your street at the survey and prepare whichever route applies.
The party wall bit: Ealing lofts almost always involve steel beams bearing near the shared wall of a terrace or semi, so the Party Wall etc. Act 1996 applies and notices go to the neighbours, which we manage entirely. These notes are a general guide (current as of July 2026), not formal planning advice for your property: the free survey confirms your street's exact position and your lawful route in writing.
Every Type, One Team

Loft Conversion Types For Ealing Homes

The right type follows the roof you already have. Each has its own detailed page with design guidance and real 2026 costs, and we recommend honestly at a free survey.

Dormer & L-Shaped Dormer

The workhorse for Ealing's Victorian and Edwardian terraces: a rear dormer loft conversion adds full head height and the L-shape over the back addition adds a second room. Usually permitted development.

Most popular£55k–£90k · L-shape £80k–£120k
Best for: terraces around the Broadway, West Ealing & Hanwell.

Hip-To-Gable

The transformation for 1930s semis: the sloping hip becomes a vertical gable, unlocking the full loft, usually paired with a rear dormer. Our hip-to-gable page covers the detail. Often permitted development.

1930s semi classic£65k–£95k
Best for: semis across Greenford, Perivale & Northolt.

Velux / Rooflight

Where the roof already has the height, a Velux loft conversion keeps the roofline untouched: fastest build, lowest cost, and the route most likely to sail through in conservation areas.

Fastest & most affordable£40k–£55k
Best for: tall Edwardian roofs & conservation streets.

Mansard

The full-width option: a mansard loft conversion rebuilds the roof slope at 72 degrees for the largest, most room-like space. Needs a full planning application, which we design to pass.

Maximum space£75k–£110k
Best for: terraces where every square metre counts.

How It Works

Our Five-Step Process

The same process behind every West London loft we have built since 2010, with no surprises in scope, timing or cost.

1

Free Survey In Ealing

Our project manager measures your loft's head height, checks the roof type and your street's planning position, and talks through the right conversion and a realistic budget. Around 45 minutes, no obligation.

2

Design, PD Check & Party Wall

Drawings and structural engineering in-house. We obtain the Lawful Development Certificate or submit the planning application, and serve party wall notices, all managed for you.

3

Fixed-Price Contract

A written contract, inclusive of VAT, covering every element. The agreed price does not change unless you request a change.

4

Build, From Outside In

Scaffold up, roof opened and weathertight fast, steels in, then the dormer or gable, insulation, plastering and first-fix, with you living at home throughout. The stairs go in near the end.

5

Completion & Sign-Off

Building control issues the completion certificate. The same project manager walks you through the finished rooms, fixes any snags and hands over your written 2-year guarantee.

Where In Ealing

The Neighbourhoods We Convert In

The whole borough, from the Broadway to the borough's edges. If your road is not listed it is almost certainly still covered: see our areas page, our Kingston loft page or our Twickenham builders page, or just call.

W5

Ealing Broadway & Common

The Queen of the Suburbs' Edwardian heartland: tall roofs made for dormers and Veluxes, with conservation pockets we design for carefully.

W13

West Ealing

Victorian and Edwardian terraces where a rear dormer or L-shaped conversion adds a bedroom and en-suite without touching the garden.

W7

Hanwell

Terrace streets between the Broadway and the Brent, ideal dormer territory, often permitted development with an LDC as proof.

W3

Acton

Period terraces and semis on the borough border, where dormer and hip-to-gable conversions turn two-bed houses into family homes.

UB6

Greenford & Perivale

Classic 1930s hipped-roof semis, the perfect hip-to-gable candidates, usually with a rear dormer for the full transformation.

UB5

Northolt & Southall borders

Thirties and post-war semis with lofts full of potential, fifteen minutes from our Hayes base, so the team is never far away.

Adds A Floor, Adds Value

The Best Square Metres In Ealing Are In Your Roof

An Ealing loft conversion adds a bedroom, often with an en-suite, without losing a metre of garden, and loft conversions are consistently rated among the best value-adding improvements a house can have, often adding in the region of 20 percent to a home's value. In a borough where family houses near the schools, parks and the Elizabeth line are permanently in demand, the extra bedroom is exactly what the market rewards, and you stay living at home while we build it.

"Half of Ealing is sitting under an unconverted roof. The families who convert first get the bedroom, the en-suite and the value uplift, and never have to move away from the street they like."

Ealing Loft Conversion FAQs

Ealing follows our standard London ranges: Velux £40,000–£55,000 inc VAT, dormer £55,000–£90,000, hip-to-gable with rear dormer £65,000–£95,000, mansard £75,000–£110,000 and L-shaped dormer £80,000–£120,000, all including structural steel and building control. We fix the price in writing after a free survey. Full breakdown in our loft cost guide or try the free calculator.
Often not. Most rear dormers and hip-to-gables are permitted development if the extra roof volume stays within 40m³ (terraced) or 50m³ (semi/detached), the dormer is set back from the eaves, sits no higher than the ridge, and side windows are obscure-glazed. Conservation areas and Article 4 streets are the exception, and mansards need a full application anywhere. We check your street at the survey and obtain the Lawful Development Certificate (£274) where the work is PD. More in our loft planning guide.
Follow the roof: Edwardian and Victorian terraces around the Broadway and West Ealing suit dormer and L-shaped conversions, the 1930s semis of Greenford and Perivale are hip-to-gable country, a tall roof suits the fast and affordable Velux route, and a mansard gives maximum space where planning suits. We recommend honestly at the free survey.
Most take 6 to 14 weeks on site: Velux fastest, dormers and hip-to-gables in the middle, mansards longest. Most of the work happens from scaffolding outside, so you stay living at home. Allow extra time before the build for design, the LDC or planning application, and party wall notices, all of which we manage.
Measure from the top of the ceiling joists to the underside of the ridge: around 2.2 metres or more usually converts comfortably, and Ealing's period roofs typically have it. Lower roofs can still work with a dormer or mansard, which add height where you need it. The free survey settles it in ten minutes, and we will tell you honestly if converting is not the right value for your house.
Usually, yes. Ealing lofts almost always involve steel beams bearing on or near the shared wall of a terrace or semi, so the Party Wall etc. Act 1996 applies and notices must be served on the neighbours, sometimes both sides. It is routine, and we manage the whole process for you so it never holds the project up.
All of them: Ealing Broadway, Ealing Common, West Ealing, Hanwell, Acton, Greenford, Perivale, Northolt and the Southall borders, covering W5, W13, W7, W3, UB6 and UB5. Our Hayes base is fifteen minutes away, so the scaffold, skips and team are local. See also our main Ealing builders page for extensions and renovations.
Loft conversions are consistently rated among the best value-adding improvements, often adding in the region of 20% to a home's value, and Ealing's family-house market, with its schools, parks and Elizabeth line links, rewards the extra bedroom and en-suite more than most. Fixed price including VAT, 2-year workmanship guarantee, and building control, gas, water and electrical certificates on completion.
