What does skylight replacement in Chichester involve?
Skylight replacement in Chichester means replacing tired domes and failed glass with a modern rooflight. We cover the PO19 district and the rest of West Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Chichester, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
From Chichester to Bognor Regis, Havant and Littlehampton, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Chichester
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. 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.
