Skylight replacement in Fakenham: what is involved?
Thinking about skylight replacement in Fakenham? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Think of skylight replacement for older extensions due a modern rooflight.
Fakenham is around 38 km from Norwich, and we survey and fit throughout that part of Norfolk, including the NR21 district.

Planning, building control and Fakenham
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
