Programme of works
Phased replacement across a building, priced from a survey
Guide ranges for supply & fit, per unit; site set-up priced separately. 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 New Malden and nearby
Fitters travel to the job, so the address is what counts. In New Malden that means postcode districts KT3, KT5 and KT1, and the same teams can just as easily take on work in Worcester Park, about 2 miles away, or Surbiton at roughly 2 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
On the day, we cover
- Old units removed, with waste taken off site
- New units fitted, sealed and weathered into the roof covering
- Roof survey of every unit, kerb and the fragile areas around them
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
- Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
How a fitting day runs
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a commercial rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes about a day per unit, longer on big roofs.
Do you need permission in New Malden?
For non-domestic roofs in England, expect building control involvement for new openings, energy limits of 2.2 W/m²K for rooflights, and fire checks where rooflights sit near a boundary or above an escape route. Smoke ventilation rooflights must be certified products, with controls commissioned by a specialist. We set out what applies to your building on the quote.
Before you get in touch
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, KT3 or nearby, confirms travel.
Common questions in New Malden
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
What upstand height and roof pitch does commercial rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Do you cover New Malden?
Yes. Fitters travel to addresses in New Malden and the surrounding districts, including KT3. 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.
Send a few photos and your KT3 postcode, and we will put together a written quote for the job.
