In reply to Mountain Lass:
I would suggest not haggling over minor issues in the survey. Unless the results are very different to what you expected (e.g. Falling in to a mineshaft, rotten structural timbers, roof now ornamental only) you may find that goodwill is worth more than minor savings.
Make sure that you and your solicitor are in agreement about who does what, and when, including anticipated costs and an anticipated schedule of payments.
Make sure all instructions to your solicitor are in writing, and that you keep a record. Send them as formal letters by post and as a PDF copy attached to an email explaining that this is a copy of the posted letter. Date everything. This is both because written communications help make sure you're both singing to the same tune, and as a fallback in case of any highly unlikely screwup by them. Be responsive to phone calls but follow them up with written confirmation of what you told them.
Make sure that they don't leave you a loft full of rubbish!
Don't let anyone bully or push you into rash decisions.
If you are gathering funds or loans from other purchasers or relatives or investments, make sure you don't exceed the FSCS protection arrangements in the mean time. Make sure well in advance that you can remove £10 from each account involved to find and problems early. Find out daily transfer limits etc.
Bin, recycle or donate everything you can well before moving.
Good luck!
