Understanding your RICS survey report

Key takeaways

• RICS survey reports use a traffic light system, condition ratings 1, 2 and 3, to flag the urgency of any issues found in a property.
• A rating of 3 doesn't automatically mean walk away. It means something needs a proper look, often by a specialist, before you commit.
• The report is split into sections covering the structure, services, grounds and legal matters, and not every page carries equal weight.
• If your findings clash with your mortgage valuation, that's normal. The two documents serve very different purposes.
• Getting quotes from the right specialists early, whether that's a damp specialist, structural engineer or your conveyancer, puts you back in control of the process.

Opening a RICS survey report for the first time can feel like getting exam results written in a language you half remember from school. There's a summary, a wall of technical terms, and somewhere in the middle a colour-coded system that's meant to make everything clearer but often adds another layer of confusion.

The good news is that once you know what you're looking at, a survey report becomes one of the most useful documents in your entire move. It tells you exactly what you're buying, not just what the estate agent's photos suggested. This guide breaks down the traffic light ratings, the jargon, and what to actually do with the information once you've digested it.

If you haven't yet commissioned a survey, or you're still deciding between report types, our guide on survey types is a good place to start before this one.

What is a RICS survey report and why does it matter?

A RICS survey report is a professional assessment of a property's condition, carried out by a chartered surveyor and written to the Royal Institution of Chartered Surveyors' Home Survey Standard. It flags defects, risks and repairs so you know what you're actually buying.

Unlike a mortgage valuation, which exists purely to reassure your lender that the property is worth what you're borrowing against, a survey report is written for you. It's your evidence, your negotiating tool and, in some cases, your early warning system for problems that could cost thousands down the line.

RICS introduced a standardised format in 2021 specifically so that reports from different surveyors would read consistently, using the same rating system and structure regardless of which firm carried out the inspection. That standardisation is exactly why the traffic light ratings matter so much. Once you understand them, you can read any RICS-compliant report, whether it's a Level 2 Home Survey or a full Level 3 Building Survey, and know what you're looking at.

For a wider look at what surveyors actually check during the inspection itself, our guide on what a house survey checks covers this in more detail.

What do the traffic light condition ratings (1, 2, 3) actually mean?

Condition ratings are a colour-coded scale from 1 to 3 that RICS surveyors use to grade the severity of any issue found. Rating 1 is green (no action needed), rating 2 is amber (repair or monitor), and rating 3 is red (serious, urgent attention required).

These ratings appear next to almost every element of the property covered in the report, from the roof and chimneys to the drainage and electrics. It's a simple system on paper, but the nuance is in how it's applied, because a rating 3 on a decorative feature is a very different conversation to a rating 3 on the roof structure.

Pro tip: don't just scan for red flags and skip the amber ones. A property riddled with rating 2s across multiple elements- guttering, pointing, minor damp- can add up to a bigger maintenance bill than a single rating 3 on something straightforward to fix.

What does a condition rating of 1 mean?

A rating of 1 means the surveyor found no visible defects requiring repair. The element is in reasonable condition for its age, and no immediate action is needed, though ongoing general maintenance is always sensible.

This is the outcome every buyer hopes to see across the board, though it's genuinely rare for an entire report to come back all green, especially on period properties. A rating of 1 doesn't mean brand new or perfect. It means fit for purpose and not currently a concern.

What does a condition rating of 2 mean?

A rating of 2 flags a defect that needs repairing or maintaining, but the surveyor doesn't consider it serious or urgent. It's the amber middle ground, worth factoring into your budget and timeline, but not a deal-breaker.

Most surveys come back with a healthy scattering of rating 2s. Cracked pointing, worn flashing, a bit of movement in an older extension- these are the bread and butter of most Home Survey reports. The key is understanding roughly what fixing each one might cost, so you're not caught out after completion.

What does a condition rating of 3, the red flag, actually mean?

A rating of 3 means the surveyor found a serious defect that needs urgent investigation, repair or replacement. It's the most severe rating and usually warrants a specialist opinion before you proceed with the purchase.

This rating tends to cause the most panic, and understandably so. But a red flag isn't automatically a reason to pull out. It's a prompt to get more information. Common examples include suspected structural movement, evidence of active damp, or roof coverings past the end of their useful life. The surveyor's job is to flag the risk, not necessarily to diagnose the exact cause or cost, which is why the next step almost always involves bringing in a specialist. Our guide to common house survey problems breaks down the issues that most frequently trigger a rating 3, and what they usually mean in practice.

How is a RICS survey report structured, and where should I focus my attention?

A RICS report is typically laid out in sections: a summary of key findings, an element-by-element breakdown of the building's condition, information on services like electrics and plumbing, and notes on legal or environmental risks. The summary is the fastest way to get your bearings.

Most reports open with an "About the inspection" section, followed by a condition summary that lists every rating 2 and 3 finding in one place. This is genuinely the most useful page in the whole document if you're short on time, because it flags everything that needs your attention without you having to trawl through forty pages of room-by-room detail.

After that, you'll usually find:

• A general description of the property, construction type and age
• An element-by-element assessment (roof, chimneys, walls, windows, floors, drainage)
• Services (electrics, gas, water, heating), which are visually inspected only, not tested
• Grounds, outbuildings and boundaries
• Risks, including damp, timber decay, and environmental factors like flood risk or Japanese knotweed
• Legal and other matters the surveyor thinks your conveyancer should follow up on

That last section is worth flagging to whoever is handling your legal work. If you haven't yet appointed a conveyancer, it's worth comparing quotes early so there's someone ready to pick up any legal queries the survey raises without delay.

What jargon comes up in a survey report, and what does it actually mean?

Survey reports use technical language to describe defects precisely, which can make them harder to read than they need to be. Terms like efflorescence, movement, and made-up ground are common, and each has a specific, non-alarming meaning worth understanding before you panic.

A few of the terms that trip people up most often:

• Efflorescence – a white, powdery deposit on brickwork caused by salts moving through damp material as it dries out. Often harmless and temporary, but worth monitoring.
• Movement – any sign that part of the building has shifted, cracked or settled. Not automatically subsidence; older buildings move naturally over decades.
• Made-up ground – soil that's been artificially built up or filled, rather than natural undisturbed ground. Relevant to foundation stability.
• Rising damp – moisture moving upward through a wall from the ground, usually where a damp-proof course has failed or was never installed.
• Woodworm (wood-boring insect activity) – can refer to old, inactive damage or a current infestation. The report should specify which.
• Non-traditional construction – any building method that doesn't use standard brick or block cavity walls, which can affect mortgage lending.

If a term isn't explained clearly enough in your report, it's completely reasonable to call the surveyor and ask them to talk you through it. Most are happy to do this, and it's far better than guessing.

What should I do if my report comes back with condition rating 3 red flags?

Start by getting a specialist opinion on the specific issue flagged, whether that's a structural engineer, damp specialist or roofer, before deciding your next move. A red flag calls for information, not necessarily panic or withdrawal from the purchase.

The process usually looks like this:

1. Read the exact wording the surveyor used. "Suspected" and "confirmed" carry different weight.
2. Get a quote or assessment from the relevant trade or specialist to understand the likely cost and scope of the fix.
3. Decide whether that cost changes your view of the price you're prepared to pay.
4. Loop in your conveyancer if the issue has any legal implications, such as unresolved planning permissions or boundary disputes tied to the defect.
5. Consider whether you need a more detailed inspection. If your original report was a Level 2 Home Survey and the red flag relates to structural concerns, a Level 3 Building Survey might give you the depth of detail you actually need.

Pro tip: always get at least two specialist quotes for a rating 3 issue before renegotiating on price. Surveyors flag risk, but they're not always the best source for an accurate repair cost, and estimates can vary significantly between trades.

How does a Level 2 survey differ from a Level 3 when it comes to reading the findings?

A Level 2 Home Survey gives a visual condition report with limited detail on the causes of defects. In contrast, a Level 3 Building Survey provides in-depth analysis, likely causes and repair recommendations. Level 3 reports are longer and more technical.

If your Level 2 report comes back with several rating 3 flags, particularly around structural elements, it's often worth commissioning a Level 3 survey rather than relying purely on trade quotes. A Level 3 surveyor will typically explain why a defect occurred, not just that it exists, which makes negotiating far easier. Our comparison guide on RICS Level 2 vs Level 3 surveys explains which is right for different property types and ages.

Why doesn't my survey report match my mortgage valuation?

A survey report and a mortgage valuation are different documents with different purposes. The valuation confirms the property is worth what the lender is advancing, while the survey assesses its physical condition. It's entirely normal for the two to disagree.

This catches a lot of buyers out. A mortgage valuation can come back with no concerns at all, while a Level 2 or Level 3 survey flags multiple issues, simply because the valuer's job was never to inspect the building in detail. If you want to understand exactly how these two processes differ and why relying on a valuation alone is risky, our guide on survey vs mortgage valuation covers this properly.

Can I use my survey report to renegotiate the price?

Yes, a survey report is one of the strongest tools you have for renegotiating. Rating 2 and 3 findings, backed by repair cost estimates, give you concrete evidence to ask the seller for a price reduction or for issues to be fixed before completion.

The trick is being specific. Vague requests like "there's damp mentioned" rarely land well. Turning up with a quote for the repair, and a clear explanation of what the surveyor found, puts you in a much stronger position. Estate agents and sellers respond better to numbers than to nervousness.

Who should I show my survey report to before completion?

Share your full survey report with your conveyancing solicitor, particularly any sections covering legal or environmental risks, boundary issues, or planning matters. They'll flag anything that needs formal investigation before you exchange contracts.

Your conveyancer isn't there to interpret the technical building elements; that's the surveyor's job, but they absolutely need to know about anything with legal weight. Things like unregistered rights of way, missing building regulations sign-off, or flood risk zoning can all affect the legal side of your purchase, and your solicitor is the one who chases these down with the seller's side. If you haven't compared conveyancing quotes yet, it's worth doing so once your survey is booked, so your legal team is ready to act on the findings without losing time.

How do I get a survey report I can actually trust in the first place?

Always confirm your surveyor is RICS-regulated and holds relevant experience with your property type, particularly for older, listed or non-standard construction homes. A properly qualified surveyor produces a more reliable, standardised report.

Not all surveyors have equal experience with every type of property. A Victorian terrace and a 1960s concrete-panel build throw up very different issues, and it's worth checking a surveyor's background before booking. Comparing quotes through Moving Compared's surveyor comparison tool means you're choosing from RICS-regulated professionals rather than gambling on the first name that comes up in a search. If you're still weighing up whether you need a survey at all, or which type suits your purchase, our complete guide to property surveys and home surveys explains the decision from scratch.

Final thoughts

A RICS survey report only feels overwhelming until you know what the traffic light system is actually telling you. Once you can separate the green from the amber, and understand that a red flag prompts more information rather than a reason to panic, the whole document becomes a genuinely useful negotiating and decision-making tool rather than a source of stress.

If you're still at the stage of booking a survey, or you want to compare quotes from RICS-regulated surveyors near you, get a surveyor quote through Moving Compared and take that part of the process off your plate.
