From house purchase only made 15 months ago:
Conveyance cost £295 plus VAT. Land registry fees plus local search fees add about £200 to this figure.
Full building survey plus written report £700. Takes surveyor about 1.5 days of work including report production.
Cost of house involved was £290k. This is relevant because of professional indemnity cover fees incurred by these professions. Means that there is a sliding scale element to their pricing structure.
Shop around for legal element, and use a conveyancer, not a solicitor.
