View Our 2025 Spray Foam Removal Cost Break Down Here
Removing spray foam insulation from your loft or roof isn’t just about cutting it out — it’s about restoring your home’s mortgageability, saleability, and long-term structural safety. But what does it actually cost?
In this guide, we’ll break down:
Average spray foam removal prices in the UK
What influences the total cost
Why quotes can vary so much
What should always be included
How to avoid overpaying or getting the job done twice
Let’s take the guesswork (and the risk) out of spray foam removal costs.
Typical Spray Foam Removal Cost in the UK
| Property Type | Loft Size | Estimated Cost Range |
|---|---|---|
| Flat / Small Bungalow | Under 30m² | £2,000 – £3,500 |
| Semi-Detached House | 30–50m² | £3,000 – £5,500 |
| Detached Property | 50m²+ | £4,500 – £8,000+ |
These prices include:
Manual removal using specialist tools
Debris and dust management
Waste removal
Basic post-removal inspection
Pre-removal consultation
Some providers may also include certification — but not all. More on that below.
What Affects the Cost of Spray Foam Removal?
Every property is different. Here’s what drives up (or down) your quote:
1. Foam Type
Open-cell is soft, flexible, and easier to remove
Closed-cell is denser and bonded more tightly — often costs more

2. Thickness of Application
Foam sprayed heavily, between rafters, or applied in multiple layers will take longer to remove and require more labour.
3. Roof Access & Layout
Tight loft hatches
Low-pitch roofs
Obstructed or boarded loft spaces
All of these increase time on site.
4. Roof Condition
If timbers are already compromised, the removal must be even more precise — and may take longer.
5. Documentation & Inspection Requirements
If you need a Spray Foam Removal Certificate, expect additional cost (usually £150–£500 depending on detail level).
What Should Be Included in a Proper Spray Foam Removal Quote?
A professional, transparent quote should include:
✔ A full breakdown of the labour, time, and methods to be used
✔ Confirmation that manual removal will be carried out
✔ Clear mention of debris removal and site clean-up
✔ Indication of whether post-removal inspection or certification is included
✔ Timeline for completion — no vague estimates
If it’s not detailed, or you’re offered a “quick fix” approach — walk away. Spray foam removal, done improperly, is one of the costliest jobs to repeat.
What’s NOT Included (But Should Be Asked About)
Certification and photographic evidence
Moisture testing or structural assessment
Replacement insulation (e.g. breathable foil)
Scaffolding or access platforms (if needed externally)
Always ask whether these are included or available — especially if your lender or surveyor requires documentation post-removal.
Can Cheap Quotes Be Trusted?
In most cases, no.
Quotes under £1,500 for full loft removal are almost always:
Cutting corners (e.g. just slicing surface foam)
Failing to fully expose timbers
Not providing certificates
Using roofers or general contractors, not insulation specialists
The end result?
You pay less up front — but still can’t sell or remortgage.
And in some cases, you pay twice when the first job fails a survey.
Is Spray Foam Removal Worth the Cost?
If spray foam is:
Preventing a mortgage or remortgage
Causing a down-valuation
Obstructing a property sale
Hiding potential damp or timber issues
Then removal is almost always financially justified.
Removing spray foam restores your property’s full value, mortgage access, and ability to move forward.
