What we fit in Brentwood
We survey, supply and fit skylights and rooflights in Brentwood and the CM14 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights.
Brentwood sits about 8 km from Billericay and 9 km from Hornchurch, and we cover the whole CM14 postcode district and the roads in between.

Planning and building rules in England
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.
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.

Skylight questions: Brentwood
Is the survey in Brentwood free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Brentwood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Brentwood?
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.
How do I book a survey in Brentwood?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Do you take a deposit?
Nothing is paid until you accept a written quote. Made-to-measure products are ordered after you accept, we tell you in writing when the order is placed, and the quote states the payment stages.
