RICS Level 2 vs Level 3 Survey: Which One Do You Actually Need?

If you're buying a home in Barnet and you've been told you need a survey, the next question is almost always: "Which one?" And honestly, it's a fair question. The different types of surveys available from RICS-regulated surveyors can seem confusing at first. But once you understand what each one actually does, the choice becomes much clearer.

I've been a RICS surveyor in North London for over 20 years, and this is without question the question I'm asked most often. Let me break it down for you properly — no jargon, no confusion.

The Two Main Types of Home Survey

Since 2021, RICS has standardised residential surveys into three levels. For most buyers in Barnet, the choice comes down to Level 2 (the RICS Home Survey – Level 2) and Level 3 (the RICS Home Survey – Level 3, formerly known as the full building survey).

What is a RICS Level 2 Home Survey?

The RICS Level 2 home survey is sometimes still referred to as a "homebuyers survey" or "homebuyers report," although RICS now uses the standardised Level 2 terminology. It's designed for properties that are:

• Built after approximately 1900
• Of conventional, standard construction
• In reasonable condition — no obvious signs of serious problems
• Not significantly altered or extended

The Level 2 survey uses a traffic-light rating system to flag issues: condition rating 1 (no action needed), condition rating 2 (watch and monitor), and condition rating 3 (urgent action required). It gives you a clear, structured view of the property's condition without going into the same level of technical depth as the Level 3.

In our experience, the Level 2 is often the right choice for a modern flat in East Barnet, a 1980s semi-detached in New Barnet or a post-war property in good visual condition.

"I'd always rather give someone a Level 2 survey that clearly identifies the real risks than recommend a Level 3 where it genuinely isn't needed — the survey has to match the property." — David Whitmore, Barnet Surveyors

What is a RICS Level 3 Building Survey?

The RICS Level 3 building survey is our most comprehensive home survey. It goes well beyond the Level 2 in terms of depth, detail and the range of issues it covers. Where the Level 2 flags potential issues, the Level 3 investigates them.

A Level 3 survey is appropriate for:

• Older or larger properties — particularly Victorian and Edwardian homes
• Properties with known or suspected defects
• Properties you plan to renovate or significantly alter
• Unusual or non-standard construction types
• Properties that have been significantly extended or converted
• High-value properties where the stakes are higher

The Level 3 provides detailed advice on all significant defects, their causes, the recommended remedial works and estimated costs. It's a much more thorough piece of work — and it's priced accordingly, but the peace of mind it provides is well worth the investment.

A Real-Life Example from Barnet

Here's a story that illustrates the difference. Last year, we carried out a Level 2 survey on a 1930s semi-detached in Finchley for a couple buying their first home. The survey was exactly the right product for the property — it highlighted some minor maintenance items and a small area of damp in the bathroom. Cost to fix: around £800. They bought the property with confidence.

A few weeks later, a different couple came to us about a Victorian terrace in High Barnet. They'd been quoted a Level 2 by another firm. We recommended a Level 3. Good call — the survey identified significant subsidence that had been poorly remediated, an inadequate roof structure and evidence of historic flooding. The buyer used the Level 3 report to renegotiate £22,000 off the purchase price. The survey cost them £650. The maths speaks for itself.

So Which One Should You Choose?

Here's our simple rule of thumb for properties in the Barnet area:

• Post-1930 property in good condition? A Level 2 home survey is usually sufficient.
• Pre-1930 Victorian or Edwardian property? We almost always recommend Level 3.
• Any property with visible defects? Level 3 every time.
• Planning to renovate or extend? Level 3 — you need to know what you're dealing with before you start.
• New build? Neither Level 2 nor Level 3 — you need a snagging survey.

Still not sure? That's completely fine. Give us a call or send us a message with the property details and we'll tell you exactly which survey we'd recommend — for free.

The Cost of Not Getting the Right Survey

Here's something worth thinking about. Every year, UK homebuyers collectively pay billions of pounds in unexpected repair costs on properties they didn't survey properly — or at all. A 2024 survey by the Royal Institution of Chartered Surveyors found that 17% of buyers who skipped a professional survey went on to discover major defects within 12 months of purchase, with average repair costs of over £5,500.

A Level 3 building survey in Barnet costs from £550. The cost of not getting one when you needed it could be tens of thousands of pounds.
