That's what a basic survey does, yes. A basic survey is only to satisfy the lender that the house is at least worth what they're lending you. I'm having a full survey, so should something arise later, which should have been spotted in my full survey, but wasn't, then I can ask some very serious questions of the surveyor/possibly even start legal proceedings if the miss was obvious and substantial enough to warrant negligence.
Your detailed survey is undoubtedly a valuable tool in identifying what might need to be done, or what could happen so that you can make an informed offer accordingly, and plan any expenditure that might be required on the property.
I agree you might have recourse in tort to claim damages against the surveyor for not spotting a potential defect, but I'd suggest this is not really protection in the sense of a warranty or insurance, given the negligence would need to be proved in court. This liability would last 6 years under the Limitation Act.
In terms of alleviating other potential issues, it's also worth getting in a wall tie company, timber expert like Bensleys for the loft, damp proofing company - to come in, most of whom will quote for free, and if reputable enough, won't identify something that isn't there, to supplement the full detailed survey.
