“Surveyor” covers a surprising number of different professions. A quantity surveyor, a valuer, a land surveyor and a building surveyor all use the same word, but do quite different jobs. If you’re buying a house, dealing with a defect or planning building work, it helps to know which one you actually need.
What a building surveyor does
A building surveyor is a specialist in the condition, construction and performance of buildings. The core of the job is understanding how buildings are put together, how they fail, and what to do about it. In practice that includes:
- Home surveys for buyers — Level 1, 2 and 3 — reporting on condition and defects before you commit to a purchase.
- Diagnosing defects — working out the cause of problems such as damp, cracking and subsidence, water penetration and timber decay, and recommending the right repair.
- Specialist investigations — focused reports on a specific concern, for owners, buyers, insurers or solicitors.
- Insurance claims work — assessing damage, cause and reinstatement cost after events such as fire, flood, escape of water or subsidence.
- Project oversight — specifying repairs, inspecting building work at key stages, and checking quality on extensions and renovations.
- Condition records — schedules of condition for party wall matters, leases and disputes.
- Advice — an independent opinion on a building question before you spend money.
What unites these is judgement about buildings: reading evidence, separating symptoms from causes, and giving practical advice. A good building surveyor is part detective, part advisor.
How it differs from other surveyors and professionals
- Quantity surveyor — manages costs and contracts on construction projects: estimating, budgets, tendering, valuations of work done and final accounts. They’re about money, not condition.
- Valuation surveyor (valuer) — gives an opinion of market value, for example the mortgage valuation your lender arranges. A valuation isn’t a condition survey; see mortgage valuation vs house survey.
- Building control surveyor — checks that building work complies with the Building Regulations, on behalf of a local authority or an approved inspector.
- Land (geomatics) surveyor — measures land and buildings, producing plans, boundaries and topographical surveys.
- Structural engineer — designs and assesses structures, with calculations: beams, foundations, underpinning schemes. Surveyors and engineers often work together; a surveyor may recommend an engineer where a structural calculation or design is needed.
When you need a building surveyor
- You’re buying a house and want to know what you’re taking on.
- You’ve found cracks, damp, rot or a leak and want to know the cause before paying for a fix.
- You’ve been quoted for remedial work and want an independent view on whether it’s needed.
- You’re dealing with an insurance claim and want technical evidence on cause and scope.
- You’re having building work done and want someone independent to check it.
Qualifications worth looking for
Building surveyors in the UK are commonly members of professional bodies such as the Royal Institution of Chartered Surveyors (RICS), the Chartered Institute of Building (CIOB) and the Residential Property Surveyors Association (RPSA). Membership grades and firm regulation mean different things, so it’s worth knowing how to check a surveyor is properly qualified.
