Apart from Everclean estimate you would have to add on Land Registry Fees which I think are around �100.00, Local Search Fee which depends on where you live but is usually between �100 - �180, and a few other disbursements from the Solicitors. The Solicitor will charge both a buying and selling fee so I would so with all of Evercleans higher estimates.
Usually an estate agents fee is about 1.25% and you have to remember to add VAT onto the Solicitors + Estate Agents fees.
Good luck with the move
