New rooflight in an existing roof in Leighton Buzzard

Guide prices

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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.

Covering LU7 and neighbouring districts

Leighton Buzzard and the districts around it, LU7, LU6 and LU5, all sit inside our working area. So does the ground between Leighton Buzzard and Dunstable (6 miles), and on towards Bletchley (6 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a new rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

On the day, we cover

• Plasterboard reveals formed inside and left ready for skim or decoration
• Joists or rafters trimmed with new timbers to carry the load around
• Insulated upstand built square, level and to the maker's height
• Upstand energy performance — We build the upstand to meet the energy limit for site-built upstands, not just to hold the rooflight up.
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.

How a fitting day runs

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a new rooflight: two to three days, weather permitting.

Do you need permission in Leighton Buzzard?

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.

Help us quote accurately

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 LU7.
