It's a while ago, but we got ours from Travis Perkins - and you could try Jewsons locally too. Old one - Recycling Centre metals skip.
Hi Alice, who did your front wall and would you recommend? I need to get mine done soon. Thanks.
We used Sel at Marmarex (email@example.com) - very good as builders go!
There's a guy called Tony who lives locally and fixed the railings at St Paul's Church a year or so ago and apparently makes all the front gates on his street - I'll see if I can get some contact details for you and dm them over.
