A Level 3 Building Survey — still widely called a full structural survey — is the most detailed RICS home survey available. MSR Surveying carries out Level 3 building surveys across London, Essex and the Home Counties: on period homes, on properties that have been altered or extended, and on any house where the condition is uncertain enough that a mortgage valuation will not tell you what you are buying.
Also known as a RICS Level 3 Survey, it offers the most thorough inspection of a property’s condition. It provides significantly more detail than a Level 2 survey and is recommended where a deeper investigation is required. The report may follow the standard RICS Level 3 format or be prepared in a bespoke format tailored to the property.
Unsure whether you need this level of detail? Compare a Level 2 and a Level 3 survey, or read our guide to what a RICS Level 3 Building Survey includes. For conventional properties in reasonable condition, a Level 2 Homebuyer Survey may be enough. See the areas we cover across London and Essex. Prices start at £499 — see what a RICS survey costs.
The survey provides expert commentary on structural defects, necessary repairs, construction methods, maintenance requirements, and potential future issues, enabling you to make a fully informed decision.
You can request a quote or book your survey online in just a few minutes. Our process is simple, transparent, and designed to make booking straightforward.

A RICS Level 3 Building Survey is recommended if you require a far more detailed inspection than a RICS Level 2 Survey. You should consider this option if the property is:
For properties carrying higher risk, a Level 3 survey provides the depth and clarity needed to understand potential issues fully.
A Level 3 is the most detailed RICS home survey, but it is still a non-invasive inspection. Floors, walls and ceilings are not opened up, fitted coverings are not lifted, and heating, electrical and drainage systems are inspected visually rather than tested. Anything sealed behind finishes or inaccessible on the day cannot be reported on directly.
What the extra detail buys you is interpretation. Where a Level 2 rates an element and moves on, a Level 3 sets out the likely cause of a defect, the repair options, and what is likely to happen if the work is left undone — and where evidence points to a problem behind the finishes, it tells you which specialist investigation to arrange before you exchange.
A RICS Level 3 Survey delivers the most comprehensive inspection available and is ideal for buyers who want a detailed understanding of the property’s structure and condition.
Your report will include:
The Home Survey Level 3 offers the most comprehensive and detailed Inspection of a property’s condition. It highlights significant issues clearly, using easy-to-understand ratings and structured reporting. To help you understand what’s included, you can view a sample (dummy) report and explore all the features, layout, and insights you’ll receive with a full survey.
A Level 3 is the same visual, non-intrusive inspection as a Level 2, carried out in far more detail and reported differently: for each defect you get the likely cause, the repair options, and what happens if the work is left undone. These are the areas where that extra detail usually matters.
Rising damp, penetrating damp and condensation can look similar on a meter and need completely different remedies. The report sets out which pattern the evidence points to, and what to do about it. Where the picture needs more work, we can carry out a separate damp report.
Much of the cracking in London property is old, stable and cosmetic. Some of it is not. A Level 3 looks at the pattern, width and location of cracking, the age of any previous repairs, and the things that commonly drive movement locally, including clay soils and nearby trees.
Coverings, flashings, valleys, parapets and flat roof finishes, together with gutters and downpipes, which cause more damp problems than almost anything else.
Rot and insect attack in roof timbers, floors and joinery, where visible and accessible, and the conditions that allow decay to continue.
The visible drainage, and the age and apparent condition of the electrical, heating and plumbing installations. Services are not tested, so where they look old or unsafe the report tells you to have them checked by the relevant specialist before you exchange.
Loft conversions, removed chimney breasts, structural openings and rear extensions: whether the work looks properly done, and what evidence you should ask your solicitor to obtain.
Older London housing stock was built with solid walls, lime mortar and timber floors, and has usually been altered several times since. That combination is exactly what a Level 3 is designed for.
If you are weighing a Level 2 against a Level 3 on an older house, our Level 2 vs Level 3 guide sets them out side by side. Send us the address and we will tell you which we would recommend.
Our RICS Level 3 Building Survey starts at £499, and the fee for your property is confirmed before you book. A Level 3 costs more than a Level 2 on the same property because the inspection takes longer and the report goes further. Our survey costs page sets out what changes the price.
A mortgage valuation confirms value for lending purposes only. It does not provide a detailed inspection of the property’s structure or condition.

The Level 3 exists for older, altered, extended, unusual or poor-condition property. In London that is not a minority of the market — it is most of the inner boroughs.
A Level 2 rates each element 1, 2 or 3. A Level 3 goes further: the likely cause of each defect, the repair options, the consequence of leaving it, and how urgent it is. On a London period property that difference is usually what decides whether you renegotiate, walk away, or proceed with your eyes open. The fee difference starts at £100 — see survey costs, or compare the two reports side by side on our Level 2 vs Level 3 page.
We cover the E, EC, WC, N, NW, W, SW, TW, IG, RM, EN and UB postcode districts, together with Croydon, Sutton, Watford, St Albans, Brentwood, Shenfield and Chesham. If your postcode is not on that list, ask us — we will tell you honestly whether we can get to it.
From £499 with MSR Surveying, which is at least £100 above our Level 2 fee. The final figure follows the size, age, type and condition of the property and is quoted as a fixed fee for your specific address before you instruct us.
Within 3 to 5 working days of the inspection, the same as a Level 2. A Level 3 takes longer on site and longer to write, but the delivery window is unchanged.
Usually, yes. Period and older homes, and anything altered or extended, are exactly what the Level 3 is designed for. On a typical London Victorian terrace there is normally movement history, roof and chimney work and past alterations to understand, and a Level 3 explains the cause rather than only recording the symptom.
