No, don`t do anything, see what the report picks up.
Houses can be nasty and people will try and hide stuff if they are trying to sell a house, trust me people try it. I have known whole walls to be have been taken back to brick and just plaster boarded over to cover damp coming in from outside in an effort that someone viewing the house wont notice (why would they when its covered) A good Surveyor would be able to potentially spot stuff like that from the outside of the house, leaks from high up valley guttering is a prime example because most of the time you cant see it you can only go from whats inside the house and a brief look from ground level outside. Another house I looked at had the chimney removed below the loft level and whoever removed the chimney was basically putting the lives of people living below it at risk by using pieces of wood to hold up about a tonne of bricks across 2 roof beams!
There is also a thread on here about a guy who made a successful claim from a surveyor who didn't identity some asbestos in a garage so yeah they tend to be over cautious when it comes to disclaimers when completing surveys just in case stuff is missed but then again only poor professionals would miss including `a building of this ages might contain asbestos` as a caveat.
Wait for the survey, they will potentially come back with a list of items that have been picked up on the survey, one or two them might be no service history for the boiler. No fixed electrical test for the electrics (who ever does this in a domestic property anyway?) and they might try and get some money knocked off the price of the house. You can try and then negotiate a reduction on the price or not its up to you as the seller and how badly you want to sell.
If you need more advice when you have had the survey post up some of the recommendations and I`ll see whats what.
