We've used London wood a couple of times & they are great. Super efficient & very competitive. They have big clients like Tate & selfridges I seem to remember.
We moved into our new house in January and I wanted our Victorian parque flooring sanded and lightened as it was very dark. I found Jussi on ************.com and he did a great job and was also a very nice guy (local too) Here's his link and number should you need it.
