What does skylight replacement in Bexleyheath involve?
Thinking about skylight replacement in Bexleyheath? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for skylight replacement include older extensions due a modern rooflight.
From Bexleyheath to Welling, Bexley and Thamesmead, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Bexleyheath
- Upstand rebuild and insulation
- Like-for-like size replacement
- Dome to flat glass upgrade
- Fixed to electric opening
- Misted glass unit replacement only
- Better thermal performance
- Usually done in a day
Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- Old glass and domes are disposed of responsibly
Do you need permission in Bexleyheath?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.

Common questions
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How do I book a survey in Bexleyheath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Bexleyheath?
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.
