Guide ranges for labour and materials, rooflight not included. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Fitting across Hampstead and nearby
Distance is rarely the deciding factor. A roof in Kilburn, 1 mile from Hampstead, gets the same survey, the same written quote and the same fitting process as one in NW3, NW6 and NW5. What changes the price is the job itself: size of unit, roof type, access and lifting. Chalk Farm, around 2 miles out, is treated the same way.
Included in the work
- Insulation fitted to the upstand faces to limit heat loss
- Kerb sized from the maker's drawing, internal and external dimensions both checked
- Roof membrane turned up, bonded and finished at the kerb top
- Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.
- Energy limit for site-built kerbs — We insulate upstands to meet the limit for site-built upstands, which is 0.35 W/m²K in England and Wales.
How a fitting day runs
On the day, the fitters check the opening and the roof deck around it, then cut and fix treated timber to the maker's kerb size, square and level, with any fall the rooflight needs built in. Insulation goes on the faces that need it, and the roof membrane is turned up and dressed so the kerb is weathertight before anyone leaves. Most upstand jobs take half a day to a day.
Planning and building rules in England
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
Getting a price from photos
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around NW3 and we will come back with a quote or a survey date.
Common questions in Hampstead
Do you cover Hampstead?
Yes. Fitters travel to addresses in Hampstead and the surrounding districts, including NW3. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
What is included in the price?
The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
Do I need planning permission for a rooflight in Hampstead?
Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
