Which Survey Do I Need? A Complete Guide to RICS Home Survey Levels 1, 2 & 3

Crowborough Surveyor gets asked this question more than almost any other: "Which survey do I actually need?" It is a completely fair question — and the answer is not always obvious, even to experienced property buyers. So let's settle it once and for all.

In this guide, we will walk through the three RICS Home Survey levels, explain when each one is appropriate, share some real-world examples from our work in Crowborough and East Sussex, and give you a straightforward framework for making the right choice.

Why Getting Your Survey Right Really Matters

Before we get into the levels, let us be honest about something. A property survey is not just a box-ticking exercise. It is your best — and often only — chance to find out about serious problems with a property before you legally commit to buying it. We have seen buyers lose tens of thousands of pounds because they chose the wrong survey or skipped one altogether.

One client — a teacher buying her first home in Crowborough — came to us after exchange having discovered significant subsidence that was not picked up by a cheap online survey. She asked us to look at the property. Within an hour, we had identified clay shrinkage movement affecting the rear wing, underpinning that had partially failed, and damp penetration through a cracked external wall. Total repair estimate: £34,000. The survey she had paid for had missed all of it.

We are not telling that story to scare you. We are telling it because the right survey — matched to the right property — could have saved her from that situation entirely.

The Three RICS Home Survey Levels Explained

In 2021, RICS updated its survey framework and introduced a clearer three-tier structure. Here is what each level involves:

Level 1 – RICS Home Survey Condition Report

The Level 1 is the most basic survey available. It uses a traffic-light rating system (Condition Ratings 1, 2 and 3) to describe the condition of different parts of the building. It does not include a valuation, does not give detailed advice on defects, and does not cover areas that are not easily accessible.

In our honest opinion, the Level 1 is only appropriate for modern new-build properties that are still under their NHBC or equivalent warranty. For any other property — certainly anything over ten years old — it simply does not give you enough information to make a confident buying decision.

Level 2 – RICS Home Survey (Homebuyer Report)

The Level 2 — still widely known as a homebuyer report — is by far the most popular survey for conventional residential properties. It is more thorough than a Level 1, covering a wider range of elements in more detail, and typically includes a market valuation and an insurance reinstatement cost estimate.

Your surveyor will inspect all accessible and visible parts of the property, flag any significant defects using condition ratings, and provide a summary of issues requiring attention. They will also highlight any legal issues worth raising with your solicitor — things like rights of way, boundary disputes or evidence of underpinned work that may affect insurability.

We recommend a Level 2 for conventional properties in reasonable condition, built in the last 100 years. Think of a 1960s semi-detached in good nick, a 1990s detached on a standard estate, or a 1970s bungalow with no obvious issues. If the property is in that category, a Level 2 will almost always give you everything you need.

"The homebuyer report is what I'd give my own family for most standard properties. It hits the sweet spot between depth and cost." — James Hartwell, Director

Level 3 – RICS Home Survey (Building Survey)

The Level 3 building survey is the most comprehensive survey available. It covers every accessible element of the building in forensic detail, includes advice on repair options and cost guidance, and is the right choice for any property that carries more risk — whether because of its age, size, construction type, or known issues.

At Crowborough Surveyor, the majority of our survey work is Level 3 — partly because East Sussex and the High Weald have so many older period properties, and partly because we believe that when the stakes are high (and buying a home is always high stakes), thorough is always better than adequate.

We recommend a Level 3 for: any property over 100 years old; non-standard construction (timber frame, thatched roof, flint walls, cob, listed buildings); properties in visibly poor condition; properties where you want to carry out significant alterations; and any property where you simply want the fullest possible picture.

Level 1 vs Level 2 vs Level 3: A Direct Comparison

So Which Survey Should You Choose?

Here is our simple framework. Start with the property's age:

• Under 10 years old, new build, no concerns: Level 1 may be sufficient — but consider Level 2 if the purchase price is significant.
• 10–100 years old, standard construction, no obvious problems: Level 2 is usually the right choice.
• Over 100 years old, non-standard construction, or any concerns: Level 3 building survey is strongly recommended.

But there is a caveat. If you are in any doubt — if the property has had extensions, if there are visible cracks, if it has been significantly altered, or if you just want peace of mind — choose the higher level. The extra cost of a Level 3 over a Level 2 is typically £200–£300. The cost of missing a serious defect can be orders of magnitude greater.

Why Local Knowledge Changes Everything

Wherever you are buying in Crowborough, Tunbridge Wells, Uckfield or the surrounding High Weald, local knowledge matters. The High Weald has specific geological characteristics — particularly Weald Clay — that can cause ground movement in dry summers. The area has a high proportion of older and listed properties. And many of the older homes in this area were built using local materials — Horsham stone, Wealden ironstone, Sussex marble — that require specialist understanding.

A surveyor who knows the area will understand the significance of a crack in a certain location on a certain type of property. They will know whether the local drainage conditions could be contributing to rising damp. They will recognise a repair that was done improperly 40 years ago and flag its implications today.

This is why, when you are buying in Crowborough and the surrounding area, choosing a local building surveyor with genuine local knowledge is not just a nicety — it genuinely affects the quality of advice you receive.
