Just wanted to resurrect this old thread to say that we had to have Worrall's out the other day when someone tried to break into our flat.
They were very good, as they were when we had them to fit the locks when we moved in.
And, thanks to them recommending decent locks when we moved in, and fitting them well, the attempted break-in was unsuccessful and we only needed some cosmetic repairs and minor disassembly/reassembly to one of the locks to refit a spring that had been knocked out of place by the force of the attempted break-in.
They gave us some good general security advice, which included advising us against getting them to do some extra work (as the locksmith explained that the work we were asking about would actually make it easier to break in, rather than more difficult).
Friendly, professional, honest, knowledgeable. Would recommend them to anyone. No connection other than as a very happy customer who is glad we've got a decent business like this in the neighbourhood.
Totally agree that Worralls are amazing - we had them out to change the locks when we moved into our house, it was a really complicated job due to very obscure locks having been used in the first place but the locksmith came back with tools and adapted another lock with a file, etc, for us. Did it all for the standard rate and refused my attempt to give him a tip given that it ended up taking him hours..
