Conservation rooflight installation in Kempston

What the job costs in Kempston

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.

Where our fitters travel

Kempston and the districts around it, MK42, MK40 and MK43, all sit inside our working area. So does the ground between Kempston and Bedford (2 miles), and on towards Ampthill (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.

Buying your own, or letting us supply

If you have bought a conservation rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the flashing kit and the roof pitch range. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What the job includes

• Rooflight set low so it sits close to the line of the roof
• Slates or tiles made good around the frame with tidy cuts
• Inside lining fitted to suit the room's ceiling or exposed rafters
• Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.
• Reusing the original covering — We plan to reuse the existing slates or tiles wherever we can.

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 conservation rooflight: one day, weather permitting.

Planning, building control and Kempston

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.

Before you get in touch

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in MK42, and we can price it.
