We’ve just sold a flat and are in the final process of buying a house. We’ve used ‘online’ solicitors both times.
The conveyancer who dealt with the sale was very good but the one we’re using to buy the house (on recommendation of the estate agent) is pretty useless. I think we were lucky with the first one.
To be honest, for the cost I don’t think you can complain about online solicitors but if you pay peanuts, you do often get monkeys.
I’d use online solicitors again unless I was buying something that I knew would need some proper sleuthing, in which case I’d pay more and try and find someone locally with a good reputation.
I’m happy to let you know who I used (for the good service), if so just drop me an email.
