For home-buyers survey I can recommend T H Woodhouse on Borough Road Birkenhead http://www.thwoodhouse.co.uk/
I've also had two structural surveys which were surprisingly cheap but if your mortgage company isn't doing a valuation you have to ask for the valuation as well which may cost extra. Unfortunately I can't remember who it was. Scary reports but they also advised on price of repairs which put most of them into perspective.
Can't recommend any conveyors though I would use licensed conveyors rather than solicitors.
