You could try Lenny @ Hamilton Walters
They are small/medium sized company but extremely skilled. There isn't anything they can't do and I have asked them to do some serious joinery at my place ontop of the double extension they were instructed for. I got their details from the EDF, they have been recommended on there loads.
I am more than happy with the results and will def use them again. They were the cheapest out of 3 quotes I received. Usually you should never go with the cheapest, you go with the middle quote but I visited a project they were working on at the time to view their work and was satisfied with what they could do.
