Rooflights for Chalfont St Peter homes and buildings
We survey, supply and fit skylights and rooflights in Chalfont St Peter and the SL9 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go.
From Chalfont St Peter to Gerrards Cross, Rickmansworth and Amersham, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules in England
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.
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.

Do I need to be at home for the survey in Chalfont St Peter?

Can you work alongside my builder in Chalfont St Peter?
