How we approach glass links & glass box roofs in Greenford
Glass links & glass box roofs in Greenford means frameless glass links joining old and new buildings. We cover the UB6 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. In Greenford, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
We work across Greater London, including Greenford, and in neighbouring towns such as Northolt and Southall. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for glass links & glass box roofs in Greenford
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
How do I book a survey in Greenford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Greenford free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
