How to Read Your Home Survey Report: Traffic Light Ratings and What to Do Next

Your survey report has arrived — probably a 20-page PDF that you were not entirely prepared for. There are numbered ratings, descriptions of defects, sections about services, references to things that need further investigation, and a lot of surveying terminology.

For most home buyers, a survey report is the most technically detailed document they receive in the whole buying process. Understanding what it means — and knowing which parts actually require action — is the difference between making a well-informed decision and either panicking at minor issues or missing something important.

This guide explains how a RICS survey report is structured, what the condition ratings mean, which sections matter most for your buying decision, and what steps to take based on what you find.

How a RICS Survey Report Is Structured

RICS survey reports follow a standardised structure, though individual surveyors and firms may present the information slightly differently. Understanding the layout helps you read it efficiently rather than getting lost in detail.

Executive summary

The first section gives an overview of the property and the key findings. This is the headline — but read it as a summary, not a substitute for the detailed sections. Important context and nuance is in the body of the report.

Section-by-section breakdown

The main body of the report works through the property systematically: roof, external walls, external areas, internal conditions, floors, damp, heating, and services. Each section receives one or more condition ratings and a written explanation.

Legal and planning notes

Many reports include a section highlighting anything the surveyor noticed that could have legal implications — planning conditions, alterations without consent, boundary features, or access issues. These are not legal advice, but they flag areas worth raising with your solicitor.

Services section

This section covers the heating system, electrics, plumbing, and gas. For a Level 2 survey, these are visually inspected only — not tested by specialist engineers. The surveyor notes the visible condition and age of each system and may recommend further specialist inspection.

Summary of condition ratings

Most reports end with a summary table listing every element inspected and its condition rating. This is useful for a quick overview but should always be read alongside the detailed descriptions.

What the RICS Condition Ratings Mean

The RICS condition rating system uses three numbers — 1, 2, and 3 — with 3 being the most serious. Some firms colour-code these as green, amber, and red respectively.

Which Sections of the Report Matter Most for Your Buying Decision

Not all sections carry equal weight. Here is how to prioritise your reading:

Roof — read this carefully

Roof repairs are expensive. Even a Condition 2 rating on an older roof can mean budgeting £5,000–£20,000+ depending on property size and material. Look for how the surveyor describes the age of the covering, whether re-roofing is mentioned, and whether they could inspect the roof void. “Not inspected” on the roof void warrants a follow-up.

Dampness — understand the type

The word “damp” covers very different problems. Rising damp, penetrating damp, and condensation have different causes, different remedies, and very different cost implications. Your surveyor should specify which type they have identified. Penetrating damp caused by a broken gutter is cheap to fix; rising damp with failed damp-proof course is much more involved.

Structure — look for anything about movement or subsidence

Any mention of structural movement, settlement, or subsidence warrants close reading. The surveyor should explain whether movement appears historic (stable, no progression) or active. Active movement or uncertainty about the cause is typically a Condition 3 that requires a structural engineer’s report before you proceed.

Services — interpret visual-only limitations honestly

The services section in a Level 2 survey is based on what the surveyor can see, not what they have tested. If the boiler is over 12 years old, if wiring looks outdated, or if there are visible drainage issues, the surveyor will note these — but a full electrical test or gas safety check requires specialist engineers. Budget accordingly if these areas are flagged.

Legal issues — flag to your solicitor immediately

If the surveyor has noted anything about alterations without apparent consent, building regulation compliance queries, or unusual access arrangements, raise these with your solicitor the same day. These are not defects in the building fabric, but they can affect your ability to mortgage, insure, or sell the property in future.

What to Do When Condition 3 Items Are Found

A Condition 3 rating should not automatically end your purchase, but it does require a clear-headed response. Here is how to approach it.

Step 1: Read the detail, not just the number

The condition number tells you severity. The written explanation tells you what the issue actually is and whether the surveyor considers it urgent for safety, structural, or financial reasons. A Condition 3 for a cracked chimney stack is very different from a Condition 3 for suspected subsidence.

Step 2: Call your surveyor

If a Condition 3 finding is unclear or alarming, call your surveyor directly. Most RICS surveyors are willing to talk through their findings and explain what “further investigation” means in practical terms. This is the fastest way to understand whether you are dealing with a manageable repair or a fundamental problem.

Step 3: Get specialist quotes before exchange

For structural concerns, significant damp, or any item where the surveyor recommends further specialist investigation — book those specialists before you exchange contracts. Getting quotes after exchange is too late: you are legally committed. Getting them before exchange gives you real cost data to base decisions on.

Step 4: Decide your position

Once you have specialist quotes, you have options: accept the costs and proceed, renegotiate the price, request the seller completes repairs, or withdraw. The survey gives you the information to make this decision. Without it, you are guessing.

When to Get Specialist Quotes — and Who to Instruct

Your survey report will often include a list of recommended specialist inspections. This is not padding — these recommendations reflect genuine areas of uncertainty or concern that a visual inspection cannot fully resolve.

Structural engineer

Required when the surveyor has found evidence of structural movement, subsidence, significant cracking, or concerns about walls, foundations, or load-bearing elements. A structural engineer’s report provides a professional opinion on cause, severity, and remedy.

Damp specialist

Appropriate when the surveyor has identified signs of rising damp or significant penetrating damp. A damp surveyor will diagnose the cause and provide a remediation quote. Be aware that some damp specialists have a commercial interest in recommending treatment — consider using an independent specialist or one recommended by your surveyor.

NICEIC or NAPIT registered electrician

If the report flags outdated wiring, visible hazards, or an unverified electrical installation, an Electrical Installation Condition Report (EICR) from a qualified electrician will confirm whether the installation is safe and compliant.

Gas Safe registered engineer

For concerns about the boiler, gas pipework, or heating system. A Gas Safe engineer can test the system properly and issue a safety certificate if it passes.

Drainage survey

A CCTV drain survey is recommended when the report notes drainage concerns, slow-draining gulleys, or settlement near drainage runs. Blocked or broken drains can cause foundation problems and are expensive to remedy once they have progressed.

Using Your Survey Report to Negotiate

A survey report is not just a technical document — it is a negotiating tool. If it identifies issues that were not disclosed by the seller and that affect the value of the property, you have a legitimate basis to renegotiate.

How to approach renegotiation

Work through your solicitor. Present the findings factually — the condition rating, what the surveyor said, and the estimated repair cost (backed by specialist quotes if you have them). Avoid emotional framing and focus on the numbers. Sellers respond to evidence.

What to ask for

You can request a price reduction equivalent to the cost of repairs, ask the seller to carry out specified works before completion, or ask for both. If the seller refuses reasonable requests in light of clear survey findings, you have to decide whether the purchase is still worth proceeding with at the agreed price — or not at all.

Timing matters

Raise renegotiation as soon as possible after receiving the report. Sellers who have been waiting weeks for exchange are more motivated to reach a resolution quickly than those who have plenty of time. Delay on your side reduces your negotiating leverage.
