Skylight replacement for Thetford: the essentials
We handle skylight replacement across Norfolk, including Thetford. 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Thetford, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
From Thetford to Bury St Edmunds, Diss and Wymondham, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Thetford
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
