How Much Does Spray Foam Insulation Removal Cost in the UK? (2026)

The short answer: open-cell spray foam removal starts from £3,150 for a typical 3-bed home, and closed-cell removal starts from £12,500, including VAT. The type of foam makes the biggest difference. Open-cell foam can be cut away by hand, while closed-cell foam is usually bonded to the roof, so removing it properly means a re-roof.

These are typical prices from the work we carry out across England and Wales. Most removal jobs take 1 to 5 days on site, and where closed-cell foam means a re-roof, your quote sets out the full programme.

Open-cell vs closed-cell: why the price is so different

Open-cell foam is soft and spongy. Our teams remove it by hand with tools, clean the rafters and re-insulate the loft. The roof itself is usually left in place.

Closed-cell foam sets hard and is normally bonded to the roof felt and timbers. Scraping it off from inside can damage the roof it is stuck to. Removing it properly means taking the tiles off and replacing the felt and battens, so the cost is closer to a re-roof. Where foam is bonded to the felt, the tiles can often be saved and refitted. Where it was sprayed onto the tiles themselves, new tiles are needed.

See open-cell spray foam removal and closed-cell spray foam removal for how each job is done.

What affects the cost of spray foam removal

• Foam type: closed-cell costs far more than open-cell because of the roofing work involved.
• Area covered: a whole roof costs more than a few rafter bays.
• Access: a small loft hatch, low headroom or boarded floors add time.
• Roof condition: damp or damaged timbers found once the foam is off need repairing.
• Tiles: whether the existing tiles can be saved or new ones are needed.
• Re-insulation: the type and depth of new insulation.

What the price should include

A proper spray foam removal quote should cover:

• removal of the foam and safe disposal of the waste
• any timber repairs, or how they will be priced if found
• for closed-cell, the full re-roof specification
• re-insulation, with the product and depth stated
• the written record you will receive at the end

After removal we re-insulate with Knauf mineral wool to the correct depth, or Actis Hybris. Our in-house team then prepares a written report for your lender, with photographs of what was done to your roof.

Spray foam installation vs removal cost

Removal usually costs more than installing the foam did. These are typical ranges for a standard loft.

We do not install spray foam. The installation figures are for reference only.

Will removing spray foam fix a mortgage problem?

Not always. Many lenders will now consider homes with spray foam, subject to their own requirements, and the government's guidance says removal does not guarantee a lender will lend. Before deciding, speak to your lender and take advice from a specialist surveyor. Our guide to which mortgage lenders accept spray foam has the current position.

If removal is right for your home, how it is done matters. A cheap removal that damages the roof can leave a bigger bill later. If your foam has already been removed and you still have problems, see spray foam removed but still have problems?

Can I remove spray foam myself?

Open-cell foam can be cut away by a careful DIYer, but closed-cell foam is a different job and usually needs roofing work. Our guide can I remove spray foam insulation myself? explains the risks.

Choosing a spray foam removal company

Spray foam removal cost FAQs

How much does it cost to remove spray foam from a loft?
Open-cell removal starts from £3,150 for a typical 3-bed home. Closed-cell removal starts from £12,500, because it usually means a re-roof.

Why is closed-cell foam so expensive to remove?
It bonds to the roof felt and timbers. Removing it properly means stripping the roof, so the cost includes roofing work as well as removal.

How long does spray foam removal take?
Most jobs take 1 to 5 days on site. A closed-cell re-roof can take longer, and your quote sets out the programme.

How difficult is it to remove spray foam insulation?
Open-cell foam is labour-intensive but straightforward. Closed-cell foam is difficult, because forcing it off from inside can damage the roof.

Is spray foam insulation banned in the UK?
No. There is no ban. The problems people face are with lending and selling, not the law.

Do you charge for the visit?
