Green Space UK Conservatory Roofing 

Costs are high so for 3 by 3 you will be charged ~15 K. After this you would expect a seemless service. But no, great customer service ends as soon as sale is done and survey is completed. Now you have to wait for dates and endure all the rude behaviour that installer may throw on you. Tread with caution.

What’s a very rough estimate price for a 3m x3m conservatory roof?

The one day installation is a straight up lie. Got a roof from here and it took 5 days over the space of a month to install, on the first day they took the old roof and left it overnight during rain. Decent product horrible company.
