House surveys and valuations, and the difference
A valuation and a survey answer different questions for different people. Confusing the two is the most expensive mistake in the whole buying process, because it is the one that leaves you finding out about the roof after completion.
A mortgage valuation is commissioned by your lender for the lender. It establishes whether the property is worth enough to secure the loan. You usually pay for it, which is why people assume it is theirs, but it is not an inspection of the property’s condition on your behalf and the report may be a page long.
A survey is commissioned by you, for you, and reports on the condition of the building.
The three RICS levels
RICS sets a common standard so that “a Level 2” means the same thing whoever carries it out.
Level 1 is the basic option, once called a condition report. It records the condition of the property, flags risks and urgent defects, and notes potential legal issues for your conveyancer. It does not advise on repairs or ongoing maintenance. Suited to a newish property in obviously good order.
Level 2 adds a more thorough look, including the roof space and drainage chambers, and does advise on defects and the repairs or maintenance they need. RICS describes it as most suitable for conventional properties in reasonable condition and simple in form and layout. This is the one most buyers of an ordinary house want.
Level 2 with valuation is the same inspection plus a market valuation and an insurance reinstatement figure. The reinstatement figure is the cost of rebuilding, not the price you are paying, and it is what your buildings insurance should be based on. Useful if you would otherwise be guessing at the sum insured.
Level 3 is the detailed one, formerly the full structural survey. An in-depth analysis of condition with advice on defects, repairs and the options for dealing with them. Worth it for anything old, anything altered a lot, anything with visible problems, and anything you plan to extend.
RICS publishes its consumer guide to the levels, which is the sensible place to check the current scope rather than relying on a surveyor’s marketing.
Scotland works differently
In Scotland the seller provides a Home Report before the property goes on the market. It bundles a Level 2 survey and valuation with an energy report and EPC, and a property questionnaire completed by the seller.
So a Scottish buyer starts with information an English or Welsh buyer would have to commission. You can still instruct your own survey on top if the Home Report raises something, or if you want Level 3 detail.
Choosing the level
Match it to the building, not the price. The usual reasoning:
| The property | Sensible level |
|---|---|
| Modern, standard construction, good order | Level 1, or skip to Level 2 if you want repair advice |
| Conventional house, reasonable condition | Level 2 |
| Pre-1900, thatched, timber-framed, previously underpinned | Level 3 |
| Heavily extended or converted | Level 3 |
| Anything you intend to alter structurally | Level 3 |
A survey is the one cost in a purchase that can save you a multiple of itself. It is also the one people cut to save a few hundred pounds on a transaction worth hundreds of thousands.
What a survey will not do
It will not test the electrics, which is a separate job for an electrician. See whether you need an EICR. It will not tell you what the council has planned for the land behind the garden, which is what searches are for. And it is not a guarantee: a surveyor reports on what was visible and accessible on the day, and will say plainly where they could not see.
Frequently asked questions
Can I renegotiate on the strength of a survey?
Often, yes. A survey that puts a figure on necessary work gives you something concrete to discuss, and before exchange either side can still walk away. Get a builder’s estimate for the significant items rather than quoting the surveyor’s range, because a seller is more likely to move against a real quote.
Does the lender’s valuer visit the property?
Sometimes. Lenders increasingly use automated or desktop valuations for straightforward cases, which means nobody goes inside at all. That is another reason not to treat a valuation as any kind of condition check.
Who do I complain to if the survey missed something?
RICS members are regulated, and the firm will have a complaints procedure, with redress available beyond it. Keep the report and the correspondence, since what the surveyor said they could and could not inspect is usually the heart of the question.
Survey costs sit outside the legal work, but the rest of the bill does not. You can compare conveyancing quotes with the legal fee, VAT and disbursements itemised before you instruct.
