Where to go for external and internal doors (London)

[SunflowerLV]

Hi there,

I am in the process of planning a whole house renovation. I need to replace all the doors in my house and have no idea where to begin. I live in SE London.

I would appreciate any recommendations and pointers/pros cons on what type of door, e.g. wooden, upvc, composite doors etc.

Many thanks!

I'd steer clear of that website.

Isn't well put together at all. Looks like a scam/fake.
