When purchasing a home, one of the most critical steps is conducting a thorough property survey. Buying a house is often the largest financial commitment many of us will make, and it’s no secret that hidden problems can lead to costly repairs later. In fact, studies show that 85% of homebuyers regret skipping surveys, with many facing unexpected defects averaging £10,000 in repairs.
Types of Home Surveys

Choosing the right home survey depends on the property’s age, condition, and your budget. Let’s break down the three main types of surveys offered by the Royal Institution of Chartered Surveyors (RICS). Each level provides varying depths of inspection, catering to specific buyer needs.
Survey Level: What It Covers, Best For, Cost (UK Avg.)
Level 1: Condition Report Basic visual check of accessible areas, no advice. New-builds in good condition. £250-£400
Level 2: HomeBuyer Report Detailed visual inspection, valuation, and risks. Modern/conventional homes (<50 yrs). £400-£600
Level 3: Building Survey Comprehensive checks, repair advice, and deep analyses. Older or listed properties. £600-£1,500
Condition Report
This is the most basic and affordable survey, focusing on the property’s general condition. It highlights major defects but doesn’t provide detailed advice or solutions. It’s suited to new builds or homes in excellent condition.
Home Buyer Report
The Home Buyer Report (Level 2) is the most popular choice for buyers. It offers a detailed visual inspection, includes a valuation, and highlights potential risks such as damp, structural movement, or outdated electrics. It’s ideal for properties under 50 years old.
Surveys:
- Affordable and widely available.
- Covers essential aspects like plumbing, electrics, and damp.
Surveys:
- Does not include invasive checks (e.g., lifting floorboards or removing wall coverings).
Building Survey
For older, larger, or listed properties, the Level 3 survey is your best bet. It’s the most comprehensive inspection, including invasive checks, detailed repair advice, and estimates for future maintenance.
What a Home Buyers Survey Covers: Full Checklist
Now, let’s dive into the core question: What does a home buyer’s survey cover? A typical survey inspects various aspects of the property, both inside and out, ensuring you’re aware of any issues before proceeding with the purchase. Below is a detailed checklist based on RICS standards.
Exterior Inspection
The surveyor will examine the exterior of the property to identify potential structural and maintenance issues. This includes:
- Roof: Checking for damaged tiles, leaks, chimney condition, and flashings.
- Walls: Looking for cracks, signs of subsidence, or damp-proofing defects.
- Windows and Doors: Inspecting for rotting frames, broken seals, and overall condition.
- Gutters and Drainage: Ensuring proper water flow and no blockages.
Interior Inspection
Inside the property, the surveyor evaluates visible areas for defects or hazards:
- Ceilings, Walls, and Floors: Checking for cracks, signs of movement, or timber decay.
- Bathrooms and Kitchens: Assessing plumbing, ventilation, and fixture quality.
- Living Areas and Bedrooms: Identifying layout concerns or issues with electrical outlets.
Services & Systems
The functionality and safety of key systems are also assessed:
- Electrical Systems: Age of wiring, safety of fuse boxes, and overall condition of installations.
- Plumbing and Heating: Boiler efficiency, water pressure, and the quality of pipework.
- Insulation and Damp Testing: Energy efficiency and damp penetration checks.
Outbuildings & Grounds
Surveys also extend to any additional structures or land boundaries:
- Outbuildings (e.g., garages, sheds): Structural integrity and foundation condition.
- Boundaries: Fences, walls, and shared responsibility issues.
Condition Ratings
Surveyors use a traffic light system to rate issues:
- Green (1): No repair needed.
- Amber (2): Minor repairs required.
- Red (3): Urgent repairs or investigations needed.
Common Issues Found & Red Flags
It’s not unusual for surveys to uncover problems. Some are minor, but others can significantly impact your buying decision. Here are the most common red flags and what they mean for buyers.
Damp and Moisture
One of the most frequently reported issues, damp can lead to serious structural problems and costly repairs. Damp-proofing treatments can cost between £2,000 and £5,000.
Roof Defects
Missing tiles, chimney cracks, or sagging roofs are common findings. Repairs can vary but may cost around £3,000- £10,000, depending on the extent.
Structural Movement
Signs of subsidence, such as cracks in walls or uneven floors, are serious concerns. Fixing subsidence can cost upwards of £10,000.
Outdated Electrics
Electrical systems older than 30 years often need rewiring to meet modern safety standards. This can cost £3,000-£8,000.
Infestation or Rot
Woodworm or dry rot affecting timber structures can weaken the property and lead to expensive repairs.
Real-Life Example
One buyer discovered drainage faults during their survey, leading to a £15,000 price reduction after negotiating with the seller.
