Nothing stops you buying a house without a survey. But if something is wrong with it, you find out after you own it, and the repair bill is yours.
It is one of the most common questions buyers ask, usually late at night with a mortgage offer in one tab and a moving quote in the other. Skipping the survey feels like an easy way to save a few hundred pounds and a week or two. Here is what you are actually giving up, in plain English, from a team that inspects homes across the Midlands and the South West every week.
Do you legally need a survey to buy a house?
No. In England and Wales there is no legal requirement to have a survey, and your solicitor will not insist on one. (Scotland is different: sellers must provide a Home Report, which includes a survey.)
The catch is a principle called caveat emptor, or "buyer beware". When you buy a property, it is up to you to find out what condition it is in. The seller must answer the property information forms honestly, but they do not have to point out every problem, and they may not know about many of them.
Buyer beware
Once you exchange contracts, the house is yours. So are its problems.
A survey is how you find them while you can still negotiate, or walk away.
Isn't the mortgage valuation enough?
This is the biggest misunderstanding we come across. A mortgage valuation is carried out for your lender, not for you. Its job is to confirm the property is worth enough to secure the loan.
The valuer may spend only a short time at the property, and some lenders now use a desktop valuation with no visit at all. They are not looking for damp, checking the roof or testing whether that crack is moving. If the house is worth the money on paper, the valuation does its job, even if it needs a new roof next winter.
So if your lender approves the mortgage, it means the bank is comfortable. It does not mean the house is in good condition.
Protects your lender
Is the house worth the loan?
- Often a short visit, or no visit at all
- No check for damp, roof or structural issues
- No advice on repairs
- Written for the bank, not for you
Protects you
What condition is the house really in?
- A thorough inspection by an RICS surveyor
- Damp, roof, movement and timber checked
- Clear advice on repairs and next steps
- Evidence you can use to renegotiate
What can go wrong if you don't get a survey?
Most problems that cost serious money are the ones you cannot see on a viewing. Fresh paint, new carpets and a well-placed rug hide a lot. These are the issues our surveyors find most often:
Damp and condensation. Rising damp, penetrating damp from failed gutters or pointing, and condensation mould. Treating the wrong type can make it worse.
Roof defects. Slipped or missing tiles, failing flat roofs, sagging timbers and poor flashing around chimneys.
Movement and subsidence. Cracks that look cosmetic can point to foundation issues, especially near trees or on clay soils.
Timber decay and woodworm. Wet rot, dry rot and beetle activity in floors, joists and roof timbers.
Japanese knotweed. It can affect your mortgage, your insurance and the price you get when you sell.
Unsafe or outdated services. Old wiring, tired boilers and drainage problems are flagged so you can get the right specialist in.
Unauthorised alterations. Removed walls, loft conversions or extensions without the right approvals.
Older and listed buildings. Period homes need breathable materials. Modern fixes such as cement render or plastic paints often trap moisture and cause the damage they were meant to stop.
None of these are rare. And on a viewing, most of them are invisible.
The real cost of skipping a survey
The survey fee is small next to what it protects. Skipping it costs you in three ways.
You pay for repairs you didn't budget for. A roof, a damp problem or structural work can easily run into thousands of pounds, often in the first year when money is already tight after moving.
You lose your chance to negotiate. A survey report is evidence. If it shows the property needs work, you can ask the seller to fix it, reduce the price, or walk away before you are committed. Once contracts are exchanged, that leverage is gone.
You have very little comeback. Because of buyer beware, you usually cannot go back to the seller unless they gave false answers on the property forms, and proving that is slow and expensive. If you had a survey and the surveyor missed something they should have spotted, you have a route to raise it. Without one, you have nobody to turn to.
Which survey do you need?
RICS Home Surveys come in three levels. The right one depends on the age, condition and type of property, not just your budget.
Not sure which fits? Tell us about the property and we will recommend the right level, with no pressure to buy the most expensive one.
Level 1
Condition Report
Best forNewer, conventional homes in good condition
- Traffic-light rating for each part of the property
- Highlights urgent problems
- Short, clear report with limited advice
Level 2
HomeBuyer Survey
Best forMost standard homes in reasonable condition
- Traffic-light ratings plus advice on defects
- Repairs and maintenance explained
- What to check further before you buy
Level 3
Building Survey
Best forOlder, larger, listed, altered or run-down homes
- In-depth inspection of structure and fabric
- Causes of defects and repair options
- What happens if a problem is left
Is it ever OK to skip a survey?
Sometimes the risk is lower. A brand new build comes with a builder's warranty, although many buyers still book a snagging inspection before completion. And if you are buying a property to knock down, its condition matters less.
For almost everyone else, and especially for anything over 50 years old, a survey is one of the cheapest forms of protection in the whole buying process. Next to the price of the house, it is a very small cost for knowing exactly what you are buying.
Frequently asked questions
Can I sue the seller if I find problems after buying? Only in limited cases, usually where the seller gave false or misleading answers on the property information forms. It is costly and hard to prove, which is why finding problems before exchange matters.
When should I book a survey? As soon as your offer is accepted. That gives time to read the report, get quotes for any repairs and renegotiate before exchange.
Can a survey make my purchase fall through? It can, but usually for good reason. More often, buyers use the findings to agree a lower price or ask the seller to put things right.
How long does a survey take? The inspection itself usually takes a few hours, depending on the size and level of survey. Your report follows within a few working days.
Do I need a survey on a flat? Yes, it is still worth it. A survey covers the flat itself and comments on the parts of the building that affect it, such as the roof and communal areas, which you may end up paying towards through service charges.
What if the survey finds something serious? You have options: ask for specialist quotes, renegotiate the price, ask the seller to fix it, or walk away. The report gives you the evidence to do any of these.
