What do conservation rooflights involve?
Across Kent, our conservation rooflights work covers slim, low-profile steel-look rooflights for period and listed roofs. Survey first, fixed price second, fitting third.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement.

Planning and building rules in England
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. 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.
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Do I need to be at home for the survey in Kent?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
