Brentwood
Villas, semis and bungalows, roof by roof
How the town's period villas, 1930s semis and bungalows each take a skylight, and what keeps the room warm after the glass goes in.
01Streets
Three kinds of Brentwood roof, three kinds of cold
Brentwood is a commuter town with a long High Street, a lot of green space round it and a very mixed set of houses. Rooflight installation in Brentwood starts with working out which of those houses you live in.
Near the station and up towards Warley you find tall Victorian and Edwardian villas, many of them split into flats or still sold as big family homes. Out around Hutton and Pilgrims Hatch the roads fill with 1930s semis and post-war houses, and a good number have grown a rear extension. Then there are the chalets and bungalows on the edges, where a bedroom or two sits inside the roof.
Those roofs give you different problems. The villas have deep rooms and tall ceilings that swallow daylight. The semis have a kitchen that ended up in the dim middle of the house. The bungalows have a landing or a hall with no window at all. A skylight can answer all three, but only if the frame, the glass and the insulation around them are chosen for the roof they go into.
Before we quote, we look for these things on the survey.
- Which room is dark at ten in the morning, and which wall it shares with the outside.
- How deep the rafters are, because that sets how thick the insulation can be around a roof window.
- Whether a flat roof over an extension has been re-covered, and what sits under the covering.
- Where the new opening would fall relative to the ceiling joists inside.
- Whether the loft is lived in, boarded or just used for storage.
02Council
Asking Brentwood Borough Council the right question
Brentwood Borough Council is the planning authority here. For most family houses a rooflight is a simple matter, and for a few it is not.
The general rules on when a roof window needs permission are in our skylight planning permission guide, and we keep them there so they are not repeated, and possibly out of date, on every town page. What belongs here is the local picture. Brentwood has a town centre with period buildings, and the borough has older villages and a good deal of green belt around the built-up edge. None of that automatically stops a roof window on an ordinary house, but it is the council that confirms whether any local restriction applies to your address.
Flats are the one to watch. A flat or maisonette does not get the same permitted development rights as a house, so a Brentwood flat conversion in one of the larger old villas needs the council's answer before anything is ordered. Consent is always required before work starts on a listed building.
03Villas
Tall Victorian and Edwardian villas by the station and Warley
The big period houses have the loftiest rooms and often the thinnest roof insulation. A skylight here can bring in light and cut the cold at the same visit.
A villa roof is steeper and the rafters are usually slimmer than on a modern house. Top-floor rooms can be dark because the windows are small and the ceilings slope in. Loft conversions done years ago may have a window that has misted or a lining that was never closed to the ceiling properly. The right answer might be a new roof window in a bedroom, or, if there is already a VELUX window that has had its day, a straight replacement that lets us renew the insulation round the frame.
These are the two choices we talk through for a villa.
Replace what is already there
Same opening, new frame and glass. It is the quicker job, there is less mess indoors, and the warm-edge glazing and fresh insulation collar tend to be the biggest gain.
Cut a new opening
Better when a landing, a box room or a bathroom has no daylight at all. It means working between the rafters, framing the opening and lining it, so we plan it with a proper survey first.
04Semis
1930s semis and post-war houses at Hutton and Pilgrims Hatch
The family houses on these roads were built with small kitchens and hallways. Extending them was the obvious next step, and it left a lot of rooms with no light in the middle.
The pattern is familiar: a side return or a rear extension with a flat roof, a long run of units, and a dining end that sits far from the back doors. A rooflight over that dining end changes how the whole room feels. The flat roofs of the 1960s to 1980s were often built with little insulation, and when we put in glass we have the chance to bring that roof up to a better standard around the opening.
A flat roof rooflight is the straightforward option, and a roof lantern works when the room is wide enough and the ceiling can take the height. Here is how we set up a typical flat roof job.
A flat roof rooflight over a semi's kitchen-diner
- Kerb
- Raised frame, insulated, fixed through the roof build-up
- Glass
- Double or triple glazed, warm-edge spacer as standard
- Opening
- Fixed, or manual or electric opening if the room needs fresh air
- Inside
- Insulated upstand or lining, closed to the ceiling
- Position
- Over the table or the worktop, not just the middle of the roof
05Extensions
Choosing glass for a Brentwood extension
Extensions are where people spend the most, and where an oversized lantern can make the room hotter in summer and harder to heat in winter.
Brentwood has plenty of good-sized plots, so extensions here tend to be generous. That makes the choice of glass more important, not less. We size the glazing to the part of the room you sit in, then pick the build-up to match. The table sets out how we think about four common shapes of space.
| Space | Glass that suits | What we protect |
|---|---|---|
| Wide kitchen-diner | Lantern over the table end | Even heat across a tall room |
| Narrow side return | Long flat rooflight | A tight seal along the wall line |
| Garden room or snug | Fixed unit, thermal blind | Comfort in a room used day and night |
| Bungalow hall or landing | Small fixed rooflight | A neat, insulated lining |

06Home working
The commuter's spare room and the attic office
Brentwood is a train town, with the Elizabeth line running into London, and plenty of people now do part of the week at a desk upstairs instead.
A box room or a loft room that has become an office is used all day, and that is when a cold window is noticed. A desk under a poorly fitted roof window feels the draught on the back of the neck, and a roof that faces south can leave the room stuffy by two in the afternoon. The fix is the same as for any rooflight: good glass, a properly insulated frame and a lining that is closed tight. A thermal blind is a sensible addition for a room you sit in for hours.
The same goes for a bedroom over a garage or a room built into the roof of a chalet on the edge of town. These are rooms people want to use more, and they are often the last in the house to be insulated properly. We look at what is behind the plasterboard before we draw up the quote, so you know whether the roof needs more than a window. Then you can decide with the full picture and no surprises on the day.
In Brentwood the spare room has become the office, and a desk under the roof shows up every cold spot, so the lining and the seal matter as much as the glass.
07Booking

We handle the Building Control notification for you, and our Building Regulations answer explains when it applies.
- Send a few details on the quote form or by WhatsApp, with a photo of the room and the roof if you have one.
- Free survey, inside and up top, with the insulation and roof build-up checked.
- The quote comes in writing, with the glazing, the upstand or flashing and the inside finish spelled out.

Brentwood questions about skylights and rooflights
Do I need to ask Brentwood Borough Council before a skylight goes in?
For most houses a roof window is straightforward, but flats, listed buildings and some other cases are different. The council confirms for your address, and our planning guide covers the general rules.
Can you replace an old roof window in a Victorian villa?
Yes. We fit a new frame and warm-edge glass in the existing opening, and we renew the insulation round it so the top-floor room stays warm.
Will a lantern make my extension too hot in summer?
It need not. We size the glass to the room, choose a glazing build-up that suits a south-facing roof, and suggest a blind for the hottest afternoons.
Can a dark hall in a bungalow get daylight?
Often, yes. A small fixed rooflight over a landing or hall brings light into the middle of the house, and an insulated lining stops it becoming a cold zone.
