What a Building Survey Actually Tells You
A building survey is a detailed, independent assessment of a property's condition, construction and defects, carried out by a qualified surveyor before you commit to buying. At Volarex, our chartered surveyors treat building surveys as a decision-making tool, not a box-ticking exercise. The report tells you what is wrong, what it will cost to fix, and what can wait.
Most buyers focus on price. The real value sits in condition. A survey exposes defects that are invisible during a fifteen-minute viewing: roof covering failures, damp penetration, structural movement, drainage problems and non-standard construction.
Condition, Defects and Repair Priorities
A good survey separates urgent defects from cosmetic ones. This distinction matters more than any single finding, because it determines whether you renegotiate, walk away, or proceed as planned.
Surveyors typically grade issues into three bands:
Immediate: structural movement, active damp, roof failure. Address before exchange.
Medium-term: worn render, ageing boiler, failing guttering. Budget within 12-24 months.
Maintenance: minor cracks, tired decoration. Monitor and plan.
Key Takeaway The single most useful part of any building survey is the repair priority list. It converts an overwhelming list of defects into a clear order of work with cost implications.
RICS Home Survey Costs and What Drives Them
RICS home survey costs vary by property, and no two quotes should be identical. Pricing depends on the property's size, age, construction type and location, plus the level of survey you choose.
A small modern flat costs far less to survey than a large period property with complex roof geometry. Older buildings take longer to inspect, often need specialist knowledge, and generate longer reports. Location matters too, because travel time and local market conditions both feed into the fee.
The honest answer is that survey pricing depends on the specifics of your property. Rather than quoting a flat figure, a reputable practice will ask about the building first. You can check current RICS guidance on home surveys to understand the standard levels before you request quotes.
Property Size, Age and Location
Three factors dominate the cost of any survey:
Size: more rooms, more roof, more to inspect.
Age: pre-1919 housing and non-traditional builds need closer examination.
Location: travel distance and local demand affect scheduling and price.
A common mistake is choosing a surveyor purely on the lowest quote. Cheap surveys often mean a drive-by inspection and a thin report. The fee you save rarely covers the defect you miss.
What Is a Level 3 Building Survey?
A Level 3 building survey is the most comprehensive RICS home survey, designed for older, larger, listed or dilapidated properties. It covers the building's structure, condition and defects in detail, and includes advice on repairs and maintenance.
Unlike a Level 2 survey, which reports condition in a standard format, a Level 3 report gives you a fuller picture. It suits properties where significant work is expected, where the building is unusual, or where you plan major renovation.
If you are buying a period cottage, a listed building, or anything with visible movement, a Level 3 survey is the sensible choice. A Level 2 is often enough for a modern, well-maintained home.
Snagging Survey for New Builds: Why It Matters
A snagging survey for new builds is a room-by-room inspection that identifies defects and incomplete work before you accept the property. New homes are not automatically defect-free, and the snagging list is your formal record of what the developer must put right.
Typical snags include poorly fitted doors, cracked plaster, uneven tiling, drainage issues and incomplete decoration. Catching these early gives you leverage. Once you have completed and the warranty period starts, getting the developer back becomes harder.
Watch Out Skipping a snagging survey before completion is the most common new-build mistake. Defects not recorded at handover often become your problem to fund, not the developer's.
How to Read a Building Survey Report
Reading a building survey report means starting with the summary, then working through the condition ratings and repair priorities. The summary tells you the headline issues; the detail explains why they matter.
Follow this order:
Read the overall condition summary first.
Note every defect rated as urgent.
Check the repair priority list and cost implications.
Flag anything requiring specialist investigation.
Compare the findings against your budget and plans.
A report is not meant to scare you off. It is meant to give you the facts to negotiate or proceed with confidence.
Choosing a Surveyor and Booking Your Survey
Choosing a surveyor comes down to qualifications, experience and communication. Look for a Chartered Surveyor and confirm the practice is regulated by the Royal Institution of Chartered Surveyors.
Ask three questions before booking:
Who will actually carry out the inspection?
Can I speak to the surveyor directly about the findings?
What is included, and what costs extra?
At Volarex, every survey is carried out by an experienced Chartered Surveyor, and you speak directly to the person who inspected your property. We cover RICS Level 2 and Level 3 reports, snagging inspections, damp investigations and specialist surveys of older and non-traditional properties. Depending on the service, inspections can include thermal imaging, photographic evidence and drone roof inspections where conditions permit.
Pro Tip Book your survey as soon as your offer is accepted. Early booking gives you time to act on findings before exchange, and it leaves room for a specialist follow-up inspection if the report flags something serious.
Buying a property without a proper survey is a gamble, and the stakes are your deposit and your peace of mind. Volarex provides RICS Level 2 and Level 3 home surveys, new-build snagging inspections and specialist reports, all carried out by a Chartered Surveyor who explains the findings in plain terms. With direct access to your surveyor, thermal imaging and drone roof inspections where conditions permit, you get clarity on condition, defects and repair priorities before you commit.

Frequently Asked Questions
What is the difference between a RICS Home Survey Level 2 and Level 3?
A Level 2 survey covers the property's general condition and flags visible defects, suitable for most modern homes in reasonable order. A Level 3 survey is more detailed, examining structural elements, hidden areas and potential problems. It suits older, period, listed or non-traditional properties where significant repair work is likely. Your surveyor can advise which level fits the property you are buying.
Do I really need a building survey for a new-build property?
Yes. New builds can carry defects that only appear after the first year, from poor drainage falls to incomplete insulation. A snagging survey for new builds identifies these issues before your warranty period ends, giving you documented evidence to pass to the developer. It is often the most cost-effective survey you can commission on a new property.
How much does a comprehensive building survey cost?
RICS home survey costs vary by property size, age, location and the level of survey chosen. A small modern flat costs less than a large period holeverage with complex features. Rather than guess, request a quote based on your property's details. Volarex can provide a tailored figure once they know the property type and your requirements.
How long does it take to receive a building survey report?
Most surveyors complete the inspection within a few hours on site, depending on property size and complexity. The written report typically follows within three to five working days. If you have a tight deadline, ask about turnaround when booking. Some practices, including Volarex, can prioritise urgent instructions where their diary allows.
Can I negotiate the holeverage price based on survey findings?
Yes, survey findings often give you a basis for renegotiation. If the report identifies significant defects, such as roof problems or damp, you can use the repair estimates to support a lower offer. A clear, well-written report strengthens your position because it documents the issues with evidence rather than opinion. Your surveyor can help you understand which defects justify a price reduction.
What does a chartered surveyor look for during an inspection?
A chartered surveyor examines the structure, roof, walls, floors, drainage, windows, doors and services visible at the time of inspection. They look for movement, damp, timber defects, poor workmanship and anything that affects value or safety. The surveyor also considers the property's age and construction type, flagging risks such as non-standard materials or historic alterations that need further investigation.
How do I choose the right surveyor for my property?
Look for a RICS-regulated surveyor with experience of your property type and local area. Ask whether you will speak directly to the person who inspects the property, and check that the report includes clear photographs and plain-English explanations. A good surveyor will answer follow-up questions after you receive the report, so ask about this before you book.
