Planning and building regulations for Witney
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Witney are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Witney
What is the biggest roof lantern you can supply?
It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.
Do large lanterns overheat a room?
A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.
How quickly can I get a roof lantern in Witney?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for OX28.
Who checks building regulations for a lantern in Witney?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
