You have found a place you can picture yourself in. The kitchen looks decent, the street seems quiet, and the estate agent has used the phrase “full of character” with suspicious enthusiasm. Then the practical question lands – what does a home survey include, and what are you actually paying to find out?
A proper home survey is there to give you clear insight into the condition of the property before you commit. It is not just a box-ticking exercise and it is not a decorative PDF to sit unread in your inbox. Done well, it helps you understand defects, likely repair issues, safety concerns and whether that charming Victorian terrace is genuinely solid or quietly plotting against your bank account.
What does a home survey include in practice?
In simple terms, a home survey includes a visual inspection of the property and a report explaining what the surveyor found. That inspection usually covers the main parts of the building, including the roof, walls, floors, ceilings, windows, doors and visible services. The report then sets out defects, highlights urgent issues and flags anything that may need further investigation.
What you get will depend on the type of survey you instruct. For most buyers, that means choosing between a RICS Level 2 Home Survey and a RICS Level 3 Building Survey. The broad aim is similar, but the detail is not.
A Level 2 survey is suited to properties that are fairly conventional and in reasonable condition. A Level 3 survey goes further and is usually better for older homes, altered properties, larger houses or buildings where condition is less predictable. If you are buying a period property in South London, for example, more detail is often money well spent. Character is lovely. Hidden movement and ageing roofs are less so.
The main areas a surveyor looks at
A home survey starts with the structure and overall condition of the building. The surveyor will inspect the outside and inside as far as access allows, looking for signs of movement, damp, decay, wear and poor repairs.
Externally, that normally includes the roof covering, chimneys, gutters, downpipes, external walls, pointing, render, windows and doors. The surveyor will note visible defects such as slipped tiles, cracked brickwork, deteriorating joinery or staining that suggests water is not going where it should.
Inside, the inspection covers ceilings, walls, floors and permanent fittings. The surveyor is looking for cracking, unevenness, damp patches, damaged plaster, timber defects and signs that previous alterations may not have been done particularly well. If floors feel springy or walls show staining, that will usually be mentioned.
The inspection often extends to built-in areas such as loft spaces if accessible, and cellars where safe to enter. These spaces can tell a surprisingly honest story about a property. Loft timbers may show leaks, insulation gaps or signs of woodworm. Basements can reveal moisture problems, structural movement or ventilation issues. They are less glamorous than the kitchen island, but far more useful.
Outside areas are also relevant. A survey may include garages, outbuildings, boundary walls and visible drainage concerns. The surveyor will also consider the site itself, especially where there are slopes, large trees close to the house or signs of ground movement.
What appears in the report
The report is where the value really shows. A good survey report should not leave you decoding vague phrases like a tired detective. It should explain the condition clearly and tell you what matters now, what may matter later, and what needs specialist attention.
Most home surveys include a condition rating system. This helps you see which issues are serious, which need repair but are not urgent, and which elements are performing as expected. If there is evidence of damp, roof deterioration, structural cracking or unsafe features, that will usually be highlighted prominently.
The report may also comment on the likely cause of defects and the implications if nothing is done. That matters because a hairline crack and a movement-related crack are not the same thing, even if both look unhelpfully crack-shaped.
You can also expect advice on repairs, maintenance and further investigations. Surveyors do not usually provide detailed costings for every issue, but they will often tell you where a roofer, electrician, damp specialist or structural engineer may need to look more closely.
Services and utilities – what is checked?
This is one of the most common misunderstandings. A home survey includes an overview of visible services, but it is not the same as a full test.
Surveyors will usually inspect visible parts of services such as electrics, petrol, water, heating and drainage, but they do not carry out intrusive testing or certification as part of a standard home survey. So, if the boiler exists and appears to be functioning, that might be noted. Whether it is efficient, compliant or nearing retirement age is another matter.
The report may recommend specialist testing if services look dated, poorly installed or potentially unsafe. This is not the surveyor being evasive. It is the correct professional limit. A home survey is a visual inspection, not an MOT with the bonnet fully off.
What a home survey does not include
It is just as useful to know what is not covered. Surveyors do not move heavy furniture, lift fitted floor finishes, open sealed-up areas or drill into walls. If part of the building is hidden or inaccessible, the report will say so.
A standard survey is also not a valuation unless you have specifically instructed one that includes valuation. Buyers often assume the survey and mortgage valuation are the same thing. They are not. A mortgage valuation is mainly for the lender. A home survey is for you.
A survey is not a legal investigation either. It will not confirm boundaries with legal certainty, check planning history in full or verify whether building regulations approval exists for every alteration. However, it may raise concerns if something looks inconsistent, such as a loft conversion with questionable access or an extension that deserves paperwork.
Pests can also fall into the “signs rather than proof” category. A surveyor may note evidence that suggests infestation or timber decay, but specialist reports are sometimes needed to confirm scope and treatment.
Level 2 vs Level 3 – the difference in detail
If you are choosing between survey types, the key difference is depth.
A RICS Level 2 Home Survey includes the main condition issues in a clear, standardised format. It is practical, efficient and suitable for many modern or well-maintained homes. You get a professional opinion on visible defects and repair priorities without pages of technical narrative for the sake of it.
A RICS Level 3 Building Survey is more detailed and descriptive. It examines construction, condition and defects in greater depth, and it is better at dealing with older buildings, unusual layouts, extensive alterations or properties where risk is higher. It can also give more context on repair options and the consequences of defects.
If the property is a 1930s semi with no obvious drama, a Level 2 may be perfectly sensible. If it is a converted house with a patched roof, old timber windows, a cellar and a whisper of damp in every room, a Level 3 is usually the grown-up choice.
Why the details matter before you exchange
The best survey reports do not just list problems. They help you make decisions.
Sometimes the result is reassuring. The property has a few routine maintenance issues, but nothing alarming. Sometimes it gives you leverage to renegotiate if repairs are more significant than expected. And occasionally it saves you from buying a problem property with a very photogenic front door.
This matters even more in busy markets where buyers can feel pressured to move quickly. Speed is useful, but buying blind is an expensive personality trait. Clear reporting and post-survey guidance can make the difference between informed compromise and nasty surprise.
For buyers in areas with a mix of Victorian, Edwardian and interwar housing, detail becomes especially valuable. Older homes can be brilliant to live in, but they often come with quirks that deserve an expert eye. Not every crack is serious. Not every damp patch means disaster. But some issues are worth catching before they become your issue.
So, what should you expect as a buyer?
Expect a home survey to include a professional visual inspection, a written assessment of the property’s condition, clear identification of significant defects, and recommendations on what needs attention or further checking. Expect clarity, not waffle. Expect context, not panic. And expect a few limits, because no competent surveyor will pretend to see through carpets and kitchen units.
The right survey gives you something more useful than a simple pass or fail. It gives you perspective. That is what helps you decide whether to proceed, renegotiate or walk away without regrets.
If you are buying a home, the goal is not to find a perfect property. In Britain, that would be optimistic to the point of performance art. The goal is to understand the one you are buying well enough to move forward with your eyes open.
