Replacing a conservatory roof in Hillingdon: what is different here
Hillingdon covers Metro-land suburbs such as Ruislip and Ickenham as well as Uxbridge, Hayes and Heathrow Airport.

Most conservatories here are on interwar and post war semis.

Homes in Hillingdon
Which roof makes most sense in Hillingdon?
With around 219 hours of July sunshine, summer heat is the bigger problem in Hillingdon. A solar control glass roof (£4,450 to £8,900 here) keeps the light and cuts the glare, but a lightweight tiled roof (£9,400 to £15,350) or a hybrid roof does far more to stop the room overheating. Blinds and films help with glare but not much with heat. Tiled vs glass roofs.
Building control and planning in Hillingdon
For a solid or tiled roof your installer applies for building control approval, either through Hillingdon Council's building control team or a registered building control approver, and you should get a completion certificate at the end. Keep it: a buyer's solicitor will ask for it when you sell.
