Skylight replacement in Walton-on-Thames: what is involved?
For Walton-on-Thames homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Walton-on-Thames, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
We work across Surrey, including Walton-on-Thames, and in neighbouring towns such as Sunbury-on-Thames and Esher. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Fixed to electric opening
- Roof window replacement in pitched roofs
- Like-for-like size replacement
- Misted glass unit replacement only
- Dome to flat glass upgrade
- Usually done in a day
- Cures most chronic leaks
Things we check at survey
- Old glass and domes are disposed of responsibly
- Upstand and roof condition decide the scope
Do you need permission in Walton-on-Thames?
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. 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.
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.
