What does skylight replacement in Chippenham involve?
Our skylight replacement service in Chippenham covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of skylight replacement for older extensions due a modern rooflight.
From Chippenham to Melksham, Devizes and Trowbridge, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Chippenham
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

More we do in Chippenham
Skylight replacement in Chippenham: questions
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Is the survey in Chippenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Chippenham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
