Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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.
Towns we list in Northamptonshire
From the larger towns to the smaller places in between, we take on rooflight fitting across Northamptonshire. The process is the same for a terrace, a farmhouse extension or an industrial unit: details first, written quote second, fitting day third. Remote and island addresses in England, where they arise, are covered by arrangement, and we tell you that before quoting.

What we do on the day
- Old rooflight or dome unscrewed, lifted out and taken away for disposal
- Packers, an adaptor or a new insulated upstand where the old kerb falls short
- Kerb inspected for rot, height, level and fall once the old unit is off
- Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.
- Energy rules for the new unit — We make sure the replacement meets the current energy limit, not just the old unit's performance.
Rules that apply in England
England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.
Common questions in Northamptonshire
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 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.
Will my new replacement rooflight leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
