RPSA Level 3 Survey: What’s Actually Involved?

RPSA Level 3 Survey: What’s Actually Involved?

A lot of people ask me what's involved in a Level 3 Building Survey, especially when it's their first time buying an older or more unusual property. As a surveyor, it's one of the most detailed inspections I do — and often the one that makes the biggest difference for a buyer.

This type of survey is all about digging deeper. It's not a quick once-over. I'm looking for signs of hidden issues, assessing the structure, and making sure the client knows exactly what they're buying into.

Before I Arrive On Site

Before the inspection day, I always do a bit of homework. This includes checking:

  • When the property was built

  • What materials it's likely made from

  • Any previous alterations or planning applications

  • Local risks like flooding, subsidence, or nearby trees

Having that context helps me focus on the right areas once I'm on site.

The Survey Day Itself

Once I'm at the property, the inspection usually takes a few hours, depending on size and condition. I'll go room by room, floor by floor, and get into the loft if I can safely access it. The garden and outbuildings are included too.

Here's what I'm usually checking:

  • Signs of movement or cracking in walls

  • Roof condition (both inside the loft and outside)

  • Damp readings and ventilation

  • Timber floors, joists and ceilings

  • Windows, doors, and insulation

  • Signs of past alterations or DIY work

  • Plumbing, electrics and heating (a visual overview)

I'm not there to scare anyone — but I do flag anything that's a potential concern. Some issues are minor and just need keeping an eye on. Others might need urgent repair or a specialist follow-up.

A Few Common Things That Come Up

Every house is different, but some issues crop up time and again — especially in older properties. These include:

  • Damp around chimney breasts or in basements

  • Timber decay in older roof structures

  • Movement in bay windows

  • DIY jobs done without proper support or lintels

  • Aging electrics or boilers

Sometimes, it's not the issues themselves that worry buyers — it's not knowing what's serious and what isn't. That's where a good report makes all the difference.

What the Report Includes

After the inspection, I put together a detailed written report. It's not a template — it's specific to your property. I include:

  • Photos of the main issues

  • Clear explanations in plain English

  • Suggested repairs and next steps

  • Rough cost brackets for work

  • Anything that might need legal checking (e.g. access or building regs)

It's all about giving you the full picture, so you can decide how to move forward — whether that's renegotiating, walking away, or just knowing what's ahead.

Why a Level 3 Survey Is Worth It

Buying a house is a massive commitment. If you're spending hundreds of thousands (or more), spending a few hundred on a detailed survey makes complete sense — especially if the property's older, extended, or looks like it's seen better days.

I've had clients pull out of purchases after reading the report, and others who've gone ahead but budgeted properly for repairs. Either way, they felt more confident in their decision.
