Pitched roof window installation in March

Guide prices in March

Guide ranges for supply & fit. 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.

Coverage in and around March

Jobs across PE15, PE16 and PE13 are part of our normal cover for March. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Wisbech and Ely are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Buying your own, or letting us supply

Your unit or ours, the fitting standard is the same. For supply and fit we choose a pitched roof window to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

Included in the work

• Rafters trimmed where the window is wider than the gap between them
• Insulation collar and vapour layer fitted to stop a cold edge
• Window frame fixed on its brackets, square and at the right height
• Scaffold or not — We look at the roof height and the window position to see whether scaffolding is needed.
• Flashing to suit the roof — We match the flashing kit to your roof covering before ordering.

What happens on the day

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A pitched roof window goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one day.

Planning, building control and March

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.

Details that speed up your quote

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as PE15.
