You have had your offer accepted, the champagne is (almost) chilled, and now someone asks which survey you want. Cue a quick search, three different names, a wide range of prices and a nagging worry that you might pick the wrong one. It is a fair worry. A survey is one of the few chances to find out what is wrong with a home before you own it, and it costs a fraction of what a missed problem can. Here are the questions buyers ask us most, answered plainly.
Is the lender's valuation the same as a survey?
No, and this catches out plenty of first-time buyers. If you are taking out a mortgage, your lender will arrange a valuation to check the property is worth roughly what you are paying. It is for the lender's benefit, not yours. It is usually brief and will not tell you about the condition of the roof, the state of the wiring or whether that damp patch is a quick fix or a long-term headache. If you want to know what you are really buying, you need to commission your own survey. Our plain-English entry on a home buyer's report is a handy primer.
What are the three types of survey?
Most UK surveyors work to the RICS Home Survey standard, which splits reports into three levels. Each goes into more depth than the last.
- Level 1 (Condition Report): a light-touch, traffic-light summary of the property's condition. It suits newer homes in good order, but it offers little advice, and most buyers will want more.
- Level 2 (Home Survey): a visual inspection that spots defects, explains what they might mean and rates each element by urgency. It can include a market valuation and an insurance rebuild figure. This is the sensible default for conventional homes in reasonable condition.
- Level 3 (Building Survey): the most detailed option. The surveyor looks more closely at the structure, checks the roof space where access allows and comments on hidden or likely defects and how repairs might be tackled. It is aimed at older, larger, extended or unusual properties.
You may also see lenders or surveyors use brand names for their own packages. Look at what is actually covered rather than the label, and check it follows the RICS standard.
How much will each survey cost?
Prices vary by region, property size and value, so treat these as ballpark figures and get quotes from a few RICS-regulated surveyors. Based on 2026 estimates from surveying and comparison sites, a Level 2 survey typically falls somewhere between £400 and £950, while a Level 3 survey generally starts at around £600 and can top £1,500 for larger or higher-value homes. Level 1 reports usually cost less than either. London and the South East tend to sit at the upper end.
It can feel like a lot to spend before you even have the keys. It helps to remember that the cost is small compared with the price of the home, and small again compared with a surprise roof or drainage bill.
Which survey suits which home?
Here is a rule of thumb. Pick the survey that matches the property, not just your budget.
- Level 2 is usually enough if: the home was built after around 1950, looks conventional, is in decent condition and has had no major alterations.
- Level 3 is worth it if: the property is old, listed or of non-standard construction, has been extended or converted, shows signs of damp, cracks or movement, or needs significant renovation.
- Level 1 may do if: the home is fairly new, you are comfortable with a lighter report and you have the budget for repairs if something turns up. Even then, many buyers prefer the extra advice a Level 2 provides.
If you are unsure, ring a surveyor and describe the property. Most will happily recommend a level, and some will tell you if the one you have chosen is the wrong fit.
What will a survey not tell me?
Surveys are largely visual. Surveyors will not lift carpets, move heavy furniture or open up walls, and they are not specialists in everything. Where something looks suspicious, such as old wiring, a boiler of uncertain age or signs of subsidence, they will usually recommend a specialist check. Do not skip that step. It is cheaper to pay an electrician or a drainage firm to take a look now than to find out after completion.
What do the traffic lights mean?
Level 1 and 2 reports use a simple colour code for each part of the property. Green means no repair is currently needed. Amber means there are defects that need attention but are not serious or urgent. Red means serious defects that need repair or further investigation soon. Reports also flag any legal or safety matters your conveyancer should look at. Having plenty of amber is normal. Red is what to take seriously.
What can I do if the survey finds problems?
A survey is a tool, not a verdict. You usually have four options.
- Get quotes: ask for repair estimates so you know the real cost.
- Renegotiate: use the evidence to ask for a price reduction or for the seller to fix things. Be reasonable and specific, and stay mindful of how the market feels. Our explainer on gazundering covers where that line sits.
- Investigate further: bring in a specialist for anything the surveyor flags.
- Walk away: if the problems are bigger than your budget or your appetite, you can withdraw before exchange of contracts, when you are not yet legally committed.
Your solicitor or conveyancer should see the report too, as it can raise questions worth putting to the seller. If you are new to the process, our step-by-step guide to how conveyancing works shows where the survey fits.
When should I book it?
As soon as your offer is accepted, and ideally before you spend money on legal fees. Surveyors can have busy diaries, so booking early keeps your sale moving. If you are buying your first home, our first-time buyer guide for 2026 walks through the rest of the timeline.
Selling? Expect a survey to land on your desk
Sellers have a stake here too. A buyer's survey is a common reason for a sale to wobble, so it pays to deal with obvious niggles before you list, from leaking gutters to blown double glazing. A tidy, well-maintained home tends to survive scrutiny better and keeps your buyer's confidence up. If you are thinking of selling, you can sell your home with Moovehub for a flat fee and keep more of the proceeds.
The short version
Do not rely on the lender's valuation. For most ordinary homes, a Level 2 survey is the right call. For anything old, altered, unusual or showing warning signs, spend a little more on a Level 3. Whatever you choose, use a RICS-regulated surveyor, read the whole report rather than just the summary, and act on what it says before you exchange.
