Can I Do My Own House Survey?

You can — and absolutely should — inspect a house yourself. What you cannot do is produce a survey, because a survey is a professional's opinion carrying professional liability, and yours carries neither.

So the honest answer is that these are two different things doing two different jobs. Your own inspection tells you whether to keep going. A surveyor's report tells you what you are buying, and gives you something to claim against if they are wrong.

Key Takeaways

• Inspecting a property yourself is free, sensible, and catches plenty before you spend money on anything.
• A survey is a professional opinion backed by insurance — that is what you are actually paying for.
• A lender's valuation is not a survey and tells you almost nothing about condition.
• Older, extended, unusual or visibly neglected properties are where a full survey earns its fee.
• Take a second viewing, in daylight, and use our printable checklist.

What you can check yourself, and should

A careful second viewing catches a surprising amount. Go in daylight, take a torch, and look at:

• Cracks — where they are, which direction they run, and whether they are wider at one end. Our guide on subsidence explains which patterns matter.
• Damp — musty smells, staining at skirting level, fresh paint in one patch only, and what the corners of external walls feel like.
• The roof, from the ground — dipping ridgelines, slipped tiles, and staining on walls below gutters.
• Windows and doors — do they stick or fail to close squarely?
• Water pressure and drainage — run the taps, flush the toilets.
• Outside — guttering, downpipes, ground levels against the wall, and anything built without obvious permission.

What you cannot do

Three things, and they are the ones that matter when something goes wrong.

Access. A surveyor gets into the loft, lifts hatches, and uses a moisture meter. You will be standing in someone's living room being polite.

Judgement. Knowing a hairline crack from a structural one, or normal settlement from active movement, is the job. Guessing wrong in either direction is expensive — you either buy a problem or walk away from a fine house.

Liability. This is the real product. A RICS surveyor carries professional indemnity insurance. Miss something significant and you have a claim. Miss it yourself and you own it.

The lender's valuation is not a survey

Worth repeating, because it is the most common and costly misunderstanding in house buying.

Your lender will value the property. That valuation exists to confirm the house is adequate security for the loan — it protects them, not you. It is often a drive-by or desktop exercise, and it will not tell you the wiring is from 1962.

See who organises a survey when buying a house for how the two differ, and note that Scotland works differently again — the seller provides a Home Report.

When to pay for a proper survey

Skipping it is most defensible on a modern, well-kept house with nothing unusual about it. Pay for one when:

• The property is older, particularly pre-1930.
• It has been extended or converted, especially without visible paperwork.
• Anything looks neglected — damp, cracking, a tired roof.
• The construction is non-standard — see Woolaway construction for why this matters.
• You are stretching financially and could not absorb a £20,000 surprise.

A survey costs a few hundred pounds against a purchase of hundreds of thousands. Where it earns its money is not finding faults, but giving you a documented reason to renegotiate — see what to do when a buyer wants a reduction after survey, read from the other side.

Frequently asked questions

Can I survey a house myself?

You can inspect it, and you should. You cannot produce a survey — that requires a qualified surveyor whose opinion is backed by professional indemnity insurance.

Is the mortgage valuation enough?

No. It exists to confirm the property is adequate security for the lender, is often done remotely, and says almost nothing about condition.

What should I look for on a viewing?

Cracks and their direction, damp smells and staining, the roofline from the ground, whether doors and windows close squarely, and water pressure. Our printable checklist covers the rest.

Do I need a survey on a new build?

Usually a lighter one, though a snagging inspection is worth having. New builds come with a warranty, but warranties have limits and snagging lists are easier to enforce before you complete.

How much does a survey cost?

A few hundred pounds for a mid-level report, more for a full building survey on a large or unusual property. Weigh it against the cost of the problem you did not find.
