Home surveysRICS Level 3 building survey

A RICS Level 3 building survey is the most thorough survey available for a home. It is designed for older, larger, altered, unusual or run-down properties, and for buyers planning major works, and it gives you detailed advice on the condition of every accessible part of the building, the most likely causes of defects, the repairs needed and when they should be done. Lansdown Associates’ RICS Chartered (Building) Surveyors carry out Level 3 building surveys, often called a full building survey or structural survey, across London, Birmingham, Liverpool, Manchester, Leeds and Northern Ireland.

Who a Level 3 building survey is for

Row of period brick houses with tall chimneys

RICS recommends Level 3 for a large, older or run-down property, a building that is unusual or altered, or where you are planning major works. Our Level 3 clients typically fall into these groups:

  • Buyers of period and older homes, for example Victorian and Edwardian terraces, and anything built before 1900 or of historic interest.
  • Buyers of larger or heavily extended homes, where alterations, loft conversions or removed walls need scrutiny.
  • Buyers of unusual or listed buildings, including non-traditional construction, timber-framed and thatched properties, and converted buildings.
  • Properties with visible problems such as cracking, damp, sagging roofs or signs of subsidence.
  • Investors and auction buyers who need to understand the real extent of repairs before bidding or exchanging.
  • Owners planning renovation, who want to know what they are dealing with before work starts.

For a conventional home in reasonable condition, a RICS Level 2 survey is usually proportionate. For a newer home in good order, see our RICS Level 1 survey.

Not sure which level you need? Read our Level 2 vs Level 3 survey guide, which compares the two in detail and explains which suits different ages, construction types and plans.

What a RICS Level 3 building survey includes

Tiled roof with dormer windows and a chimney

The surveyor carefully and thoroughly inspects the inside and outside of the main building and all permanent outbuildings, covering as much of the property as is physically accessible, and carries out a desk-top study and enquiries about matters affecting the property, including contamination and environmental risks.

The structure and fabric

  • Roofs, chimneys, parapets and rainwater goods, including flat roofs and hatches reachable safely by ladder.
  • Walls, foundations (as far as can be judged from visible evidence), floors, windows, doors and joinery.
  • The roof space, entered where safe, with the roof structure examined and small corners of insulation lifted to identify its type and thickness.
  • Evidence of structural movement, subsidence, dampness, condensation, timber decay and insect attack.

Services, grounds and flats

  • A visual inspection of the visible heating, electrical, plumbing and drainage installations, with recommendations for specialist testing where needed.
  • Boundaries, permanent outbuildings and shared areas.
  • For flats, communal areas and, within the flat’s boundary, drains, lifts, fire alarms and security systems in normal use.

Energy

  • A review of the EPC rating, a check for obvious discrepancies, commentary on energy matters and advice on whether the EPC’s recommended improvements are appropriate for the building.

The surveyor will not open up the fabric of the building, lift fitted floor coverings or move heavy furniture without the owner’s consent, or where there is a risk of injury or damage. Where access is limited, the report explains what could not be inspected and any further investigation required.

What your Level 3 report gives you

Reading a survey report

A Level 3 report is written to give you a detailed understanding of the property so you can make a reasoned decision about buying, repairing or upgrading it. For each main element you receive:

  • A description of how it is built and the materials used.
  • Its condition and a condition rating (3 = serious or urgent, 2 = needs repair but not urgent, 1 = no repair currently needed, NI = not inspected).
  • The most probable cause of any defect, based on the inspection.
  • What repairs are needed, the options available and the likely timescale.
  • The identifiable risk of potential or hidden defects, for example where timbers are concealed.

The report also explains risks to the building, grounds or people and how to resolve or reduce them, gives general advice and questions for your legal adviser if the property is leasehold, and lists documents your conveyancer should obtain.

Repair cost estimates

Where practicable and agreed at the point of instruction, we provide estimated costs for identified repairs and necessary work. This helps you budget for the months after you move in and gives you firm ground to renegotiate the price or ask the seller to put things right.

How we carry out a Level 3 building survey

  1. Initial consultation. We discuss the property, your plans (such as extending or opening up rooms) and anything that concerned you at the viewing.
  2. Desk-top study. We review available information about the property and its location before visiting.
  3. On-site inspection. A RICS Chartered Surveyor carries out a thorough inspection, typically a much longer visit than a Level 2 survey.
  4. Detailed report. You receive a clear written report with photographs, normally within 7 to 10 working days of the inspection.
  5. Post-survey consultation. We talk you through the findings and next steps, including whether specialist reports (for example, a drainage or electrical test) are needed before exchange.

  • Diagnosing defects is our day job. We also act on dilapidations, schedules of condition and housing disrepair, and our director, John Jackson MRICS MEWI, is a member of the Expert Witness Institute (EWI). That work trains us to find the cause of a defect, which is what decides the right repair.
  • We are independent: we do not sell building work or treatments.
  • Our reports set out clear priorities in plain English, and we follow up with a call to talk them through.

I have an investment company that predominantly buys residential property in auction. We use Lansdown Associates to undertake pre-purchase surveys on every property we intend to buy. Most recently, John identified significant issues on a property in Anfield and saved us £180,000.00. We were literally about to buy until we read the report. We can’t thank him enough

Frequently asked questions

It is the modern equivalent of what was commonly called a full structural survey. It covers the whole building, including the structure, but it is not a structural engineer’s calculation-based report. If the surveyor suspects significant structural issues, the report will recommend further investigation by a structural engineer.

When the property is older, large, extended, of unusual construction, listed or in poor repair, or when you plan significant works. The extra depth on causes, remedies and timing is usually where the value lies in these properties.

The surveyor checks for dampness using a moisture meter and visual evidence, and explains the likely cause and remedy. Where the cause needs more investigation, we can carry out an independent damp survey using more detailed testing.

No. A Level 3 building survey reports on condition, not market value. Your lender will usually arrange its own valuation.

Yes. Auction buyers are often committed at the fall of the hammer, so we recommend arranging the survey before the auction date. Get in touch as soon as you have the catalogue details.

Yes. RICS designs Level 3 to help owners plan repairs, maintenance and upgrading, not only to support a purchase.
