Buying a home? A pre-purchase cavity wall insulation survey gives you certainty about what’s hidden inside the walls before you commit.

Many UK properties contain old, failed or unsuitable cavity wall insulation that can cause damp, mould, heat loss and expensive remedial works after completion. Unfortunately, these issues are rarely identified during the buying process.

EPCs and Homebuyer Surveys Are Not Enough

EPCs and standard homebuyer surveys do not assess the condition of cavity wall insulation.
They often rely on assumptions based on the age of the property — and in many cases, those assumptions are incorrect.

Only a specialist cavity wall insulation inspection can accurately confirm whether insulation is present, what type it is, and whether it is fit for purpose.

What Our Pre-Purchase Survey Includes

Our cavity wall insulation pre-purchase survey provides a clear, factual assessment so you can make an informed decision.

We will confirm:

•  Whether the cavity walls are empty and suitable for insulation
•  What insulation material (if any) has been installed
•  Whether the insulation is fully filled or contains voids
•  The condition and performance of the existing insulation
•  An estimated cost to remove/extract failed insulation
•  An estimated cost to install new EPS Bonded Bead insulation

Why a Cavity Wall Survey Before Buying Is Important

Cavity wall insulation has a significant impact on:

•  Energy efficiency
•  Heating costs
•  Internal comfort
•  Damp and condensation risk
•  If insulation has failed or was incorrectly installed, remedial works can cost thousands of pounds once the property is yours.

A pre-purchase cavity wall survey allows you to:

•  Identify hidden defects before exchange
•  Budget accurately for future works
•  Renegotiate the purchase price if necessary
•  Avoid unexpected post-completion costs

Who This Survey Is For

•  Home buyers and investors
•  Buyers of older properties (1930s–1990s builds)
•  Anyone concerned about damp, cold rooms, or energy efficiency
•  Purchasers wanting clarity before committing financially

Peace of Mind Before You Buy

Insulation can make a home warmer, more efficient, and cheaper to run — but only when it’s suitable and correctly installed. If existing insulation is no longer fit for purpose, it’s far better to know before you complete the purchase.

A pre-purchase cavity wall insulation survey gives you that confidence.
