What a survey explicitly does not cover

This is written to be used rather than admired. Each section below is a decision about survey limitations, and each one has a default.

Visible and accessible is a strict limit

A surveyor does not lift fitted carpets, move heavy furniture, open up walls, or take up floorboards. Roof voids may be inspected from the hatch rather than traversed, and some are not entered at all. Drains are usually not surveyed unless a specialist drainage inspection is commissioned separately.

Everything concealed by that limit is where the expensive problems tend to live, which is the central irony of the exercise.

Services are observed, not tested

Most survey levels comment on the apparent age and condition of electrical, gas, heating and plumbing installations without testing them. A recommendation to have the electrics tested by a qualified electrician is a real recommendation, not boilerplate. Testing requires separate specialist inspections, each with its own fee and its own certificate.

On an ordinary week, a property with original wiring from decades ago will be flagged, and the flag is the beginning of the enquiry rather than the end.

Occupied properties limit inspection

Sellers belongings, stored boxes, wardrobes against walls and rugs over floors all obstruct exactly the surfaces a surveyor wants to see. Surveyors record these limitations, and buyers frequently read past them.

In practice, where a significant area could not be seen, asking for a return visit after the property is emptied is sometimes possible before exchange. At minimum, the limitation should be treated as an unknown rather than as an absence of problems.

Legal matters are not the surveyors job

Boundaries, rights of way, covenants, planning consents and building regulation compliance are legal questions for a conveyancer. A surveyor may note that an extension exists and cannot confirm that it was consented. Similarly, a surveyor does not confirm the lease terms, the service charge or the ownership of a shared drive.

Buyers who assume the survey covers these arrive at completion with a gap nobody filled.

Hazards and specialist risks

Asbestos, radon, contaminated land, invasive plants and fire safety in blocks are commonly outside the standard scope or limited to a visual note. Where the property age or location suggests a risk, a specialist assessment is the appropriate step. Environmental and ground searches from the conveyancing side cover some of this, and the two exercises should be read together.

In practice, nobody coordinates that reading except you, unless you ask someone to.

Some of this will suit you and some will not, and that is the point.

Read the report properly

Start with the limitations and the further investigation recommendations rather than with the summary ratings. Ask the surveyor to talk you through it; most will, and a conversation clarifies severity in a way a report cannot.

Ask specifically what worried them and what they would do if buying it. This is general information, and only a qualified surveyor can advise on a particular property.

The takeaway

Read the exclusions first. What the surveyor could not see is the part still to be checked.

Pick the one that costs you least, and let the rest wait.
