Spray foam removal cost in the UK
Quick answer
Professional spray foam removal in the UK typically costs £50–£80 per m². For a standard 100 m² loft that is usually about £5,000–£8,000, and across common UK loft sizes most homeowners pay roughly £3,000–£8,500 in total.
Open-cell foam sits at the lower end of that range (£50–£65 per m²). Closed-cell foam is denser, bonds harder to the timber and usually costs £65–£80 per m².

Prices at a glance
Open-cell vs closed-cell spray foam removal cost
Foam type is the biggest single driver of price. If you do not know which you have, a removal specialist can usually tell from photographs or the original installation paperwork.
| Foam type | Typical rate | Why it differs |
|---|---|---|
| Open-cell | £50–£65 per m² | Softer and lighter, so usually quicker to strip |
| Closed-cell | £65–£80 per m² | Denser, bonds harder to timber, needs more time and equipment |
Example totals by loft size
Worked from the rates above with standard access. Treat them as guide ranges — restricted access, repairs and re-insulation are extra (see below).
| Sprayed area | Open-cell | Closed-cell |
|---|---|---|
| 60 m² | £3,000–£3,900 | £3,900–£4,800 |
| 80 m² | £4,000–£5,200 | £5,200–£6,400 |
| 100 m² | £5,000–£6,500 | £6,500–£8,000 |
How the area is measured
Spray foam is applied to the underside of the roof, so quotes are usually measured on the sloping roof area rather than the loft floor. On a pitched roof the slopes are larger than the floor beneath them, so a quote can show more square metres than your floor plan. Ask how the area was measured if two quotes disagree.
Reading a quote
What does a typical spray foam removal quote include?
Usually included
- Labour and the specialist removal method for open- or closed-cell foam
- Protective equipment and safe working in the loft
- Bagging and removal of foam waste from site (confirm the disposal route on the quote)
- A basic tidy of the work area
- A written summary or removal report (wording varies by contractor)
Often extra — ask before you sign
- Timber repairs — roughly £200–£1,000+ if damage is found
- Re-insulation — roughly £300–£1,500+ depending on product and area
- Restricted access — often £5–£15 per m² extra
- Separate inspection or certificate — if your lender asks for independent evidence
Wording on removal reports varies between contractors. Ask whether the quote includes a written report, and ask your lender or surveyor whether they want anything further — some want an independent inspection after removal. See spray foam removal certificates.
Cost factors
What affects spray foam removal cost?
- Foam type
- Open-cell or closed-cell — the biggest single driver of price.
- Area covered
- A full roof costs more than partial coverage. Quotes are usually per m² of sprayed roof.
- Access
- Small hatches, low headroom or scaffolding often add £5–£15 per m².
- Waste disposal
- Commonly £50–£200. Check it is on the quote and how the waste is handled.
- Region
- London and the South East usually sit toward the top of the range.
- Condition of the roof
- Moisture, rot or wiring complications add repair time and cost.
Regional guide
Indicative loft removal rates. Labour and travel costs move prices within the national range.
| Area | Typical rate |
|---|---|
| London & South East | £65–£80 per m² |
| Major cities (e.g. Manchester, Birmingham) | £58–£72 per m² |
| Scotland (e.g. Edinburgh, Glasgow) | £55–£70 per m² |
| Rural areas and harder logistics | £55–£70 per m² |
| Wales | £52–£66 per m² |
| Northern England | £50–£65 per m² |
Most three-bedroom homes take 2–5 days once work starts, depending on roof complexity, foam type and access.
Removal vs repair
How removal cost compares with roof repairs
If moisture or decay has been left to develop behind the foam, remedial roof work can cost far more than removal alone — full roof replacement is commonly £10,000–£30,000 depending on the size and specification of the roof. Removal is not a substitute for repair where damage already exists: a proper survey should tell you which you need.
What removal can do
- Lets a surveyor or valuer inspect the roof timbers again
- Can help a sale or remortgage move forward if the lender’s or surveyor’s written requirements are met
- Reduces the risk of moisture problems going unnoticed behind the foam
- Leaves a paper trail — photos, invoice and report — for buyers and valuers
Removal does not guarantee a mortgage offer. Each lender and valuer applies its own rules.
Getting quotes
How to get an accurate spray foam removal quote
- 1
Get the requirement in writing
Note exactly what your lender, buyer or surveyor has asked for before anyone quotes.
- 2
Share clear loft photos
Photos and any installation paperwork help a specialist judge foam type and access.
- 3
Get more than one site visit
Especially when access is awkward, the foam looks closed-cell, or a sale or remortgage depends on it.
- 4
Compare like for like
Check waste, report, repairs, re-insulation and VAT are treated the same way in each quote.
- 5
Check the paperwork is in scope
Do not book on price alone if the evidence your lender wants is missing from the quote.
Can I remove spray foam myself to save money?
DIY removal is strongly advised against. The risks include exposure to dust and chemicals, damage to timbers or wiring, incomplete removal that a surveyor will still reject, and mistakes with waste disposal. It also leaves you without the paper trail a lender or buyer may ask for. Why DIY removal goes wrong.

How much does spray foam removal cost in the UK? +
Most professional jobs cost £50–£80 per m², which is usually £3,000–£8,500 in total depending on loft size, foam type and access. A standard 100 m² loft typically costs £5,000–£8,000.
Is closed-cell spray foam more expensive to remove? +
Yes, usually. Closed-cell foam is denser and bonds harder to timber, so it is typically priced at £65–£80 per m², against £50–£65 per m² for open-cell.
Does the removal price include a certificate? +
Not always. Ask whether the quote includes a written removal report, and ask your lender or surveyor whether they want any further inspection or certificate after removal.
Will paying for removal guarantee a mortgage? +
No. Lenders and valuers decide case by case. Removal and good evidence may help you meet a written requirement, but they do not guarantee an offer.
Why do UK lenders reject some spray foam properties? +
Usually because the foam hides the roof timbers from inspection, and because of concerns about trapped moisture and ventilation. Policies vary by lender and by how the foam was installed.
Should I get more than one quote? +
Yes, when the job is large, access is difficult, or a sale or remortgage depends on it. Compare what each quote covers — waste, report, repairs and VAT — not just the headline price.
