You have to get a valuation report for the bank, usually costs around 130 Euros. A structural survey is something you decide upon. It will give you information regarding the general state of the house, i.e. heating systems, plumbing, insulation, roof, dampness. etc.... it is usually recommended to have this carried out to avoid hidden surprises... This usually costs around 400 Euro . If you get a surveyor to do both valuations you usually get it cheaper ( I got quoted 432 for both) but you have to contract a surveyor that is on the panel of the bank, so check with the bank first if you decide to go down that route.
