Skylight replacement for Biggleswade: the essentials
We handle skylight replacement across Bedfordshire, including Biggleswade. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Skylight replacement suits older extensions due a modern rooflight.
From Biggleswade to Sandy, Letchworth Garden City and St Neots, the same survey-first process applies: measure, specify, fix the price, then fit.

- Like-for-like size replacement

Before you order: points to check

- Upstand and roof condition decide the scope
Do you need permission in Biggleswade?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about skylight replacement in Biggleswade
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need to be at home for the survey in Biggleswade?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Biggleswade?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
