Conservation rooflights for Northolt: the essentials
For Northolt homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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 conservation rooflights include period, listed and conservation-area roofs.
Neighbouring towns include Greenford (2 km) and Harrow (4 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Northolt
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.

Some makers produce bespoke sizes to match an existing opening. We can survey and quote.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.

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.
