★★★★★ Rear dormer
Two bedrooms and a bathroom out of a loft we used for storing boxes. The number on the quote was the number we paid.
S Sarah Bolton · Sept 2025
★★★★★ Hip-to-gable
Four weeks start to finish, and they swept up every evening — which mattered with a toddler in the house.
D Daniel Chorlton · June 2025
★★★★★ Velux
They talked us out of the bigger option because our roof did not need it.
P Priya Stockport · Mar 2025
★★★★★ Rear dormer
Building control paperwork was all handled. We never had to chase anybody once.
M Mark Preston · Jan 2025
★★★★★ Wrap around
The CAD drawing sold it to my husband. Seeing the staircase landing made the whole thing real.
E Elaine Lytham · Nov 2024
★★★★★ Roof-lift
Our loft was 2.1m so I assumed it was a no. They dropped the landing ceiling and it works beautifully.
J Joseph Bury · Aug 2025
★★★★★ Hip-end dormer
Second conversion we have had done in the family. Straight back to the same team, no hesitation.
N Nadia Didsbury · May 2025
★★★★★ Velux
Quiet, tidy, and they warned us the day the steels were coming so we could work elsewhere.
T Tom Warrington · Feb 2025
★★★★★ Rear dormer
The valuation came back £62,000 higher than before the work. Best money we have spent on the house.

The six we're asked every week.

Anything else, ask the surveyor — the visit is free whether you go ahead or not.

Usually not. Most conversions fall under permitted development, up to 50m³ for a detached or semi and 40m³ for a terrace. Conservation areas, listed buildings and designated land are the exceptions, and we tell you which applies at the survey.

Three weeks for a Velux, four for a rear dormer, around six for a wrap around. Plans and approval run before that — typically two to four weeks from signing.

There is dust, but the loft is sealed off and the stairwell is only cut through late in the build. Scaffolding and a rear hoist keep most material out of the house entirely.

No. Almost every customer stays in the house. Water is off for a few hours when radiators go in, and there is one noisy day when the steels land.

2.2m from the ceiling joists to the underside of the ridge is the working minimum — 2.4m on modern trusses. If you are slightly short and have generous ceilings below, dropping the first-floor ceilings is often possible. A roof-lift is the other route.

Velux conversions start at £24,000 and a wrap around at £48,000. After the survey you get one fixed written figure covering structure, staircase, insulation, plastering and building control.
