Quick Answer: Can You Get a Mortgage on a Home With Spray Foam?
In many cases, not without additional steps. As of June 2026, over 50 UK mortgage lenders restrict lending on properties where spray foam insulation is present, and all equity-release providers surveyed by the HomeOwners Alliance refused outright. However, removal is not automatically required: an independent inspection under the Property Care Association (PCA) Spray Foam Inspection Protocol is the essential first step, and in some cases a property can be made mortgageable without full removal.
Why Lenders Refuse or Restrict Spray Foam Properties
Mortgage lenders make lending decisions based on the long-term security of the property — they need confidence that the building will retain its value and structural integrity over the mortgage term. Spray foam insulation raises two specific concerns that cause lenders and their surveyors to hesitate.
Surveyors cannot inspect the underlying timbers. When spray foam is applied to the underside of roof rafters or across loft joists, it encases the timber. A standard mortgage valuation survey cannot assess the condition of the wood beneath without removing the foam first. Because the surveyor cannot verify the structural health of the roof, the Royal Institution of Chartered Surveyors (RICS) has highlighted that lenders may choose not to lend rather than accept an unknown risk.
Condensation, moisture, and rot risk. Closed-cell spray foam in particular can create a vapour barrier against the timber surface. If incorrectly installed — or if the foam develops cracks over time — moisture can become trapped between the foam and the wood, creating conditions where rot and decay may develop undetected. Even open-cell foam, which is more breathable, can hold moisture if it has been applied too thickly or without adequate ventilation.
These are not theoretical concerns. The HomeOwners Alliance and others have documented cases where roof structures were found to be deteriorated only once foam was removed.
The Scale of the Problem: ~250,000 UK Homes Affected
This is not a niche issue. Approximately 250,000 UK homes are estimated to contain spray foam insulation, according to figures cited in a House of Commons Library briefing on the subject. A substantial proportion was installed under the government’s Green Homes Grant scheme — a well-intentioned initiative that offered vouchers for home insulation improvements, but which has been associated with concerns about installer vetting and foam products.
The BBC has reported on the issue, covering homeowners left unable to sell or remortgage following spray foam installation, including cases where elderly residents had foam fitted by door-to-door salespeople with no clear explanation of the mortgage implications. The HomeOwners Alliance has called for clearer guidance from lenders and continues to advocate for affected homeowners.
The problem affects homes across England, Scotland, and Wales, and spans all property types — terraced houses, detached homes, bungalows, and ex-local-authority properties alike.
Step 1 — Independent Inspection Under the PCA Protocol
Removal is not always the answer — and it should never be the first step.
The Property Care Association (PCA) has developed a Spray Foam Inspection Protocol (introduced in 2023, with a register of registered surveyors) that provides a standardised, independent basis for assessing whether foam in a given property is causing problems — and whether removal is actually necessary. Such reports are increasingly considered by lenders and conveyancers when deciding how to proceed.
A PCA-protocol inspection involves a qualified, independent inspector visiting the property to assess:
- The type of foam present (open-cell or closed-cell)
- The coverage, thickness, and adhesion of the foam
- The visible condition of any accessible timbers
- Whether moisture ingress or existing timber damage is present
- Whether the installation appears to conform to recognised standards
The result is a written inspection report. In some cases — particularly where foam has been correctly applied, timbers are sound, and the lender is willing to consider the case — this report alone may support a mortgage application with a case-by-case lender. In other cases, the report will confirm that removal is the appropriate route, and many lenders still require removal.
We recommend beginning with an inspection rather than proceeding directly to removal. It is the most cost-effective first step, and it gives you accurate information on which to base all subsequent decisions. Find out more about our inspection service.
Step 2 — Removal & RICS-Verified Certificate (When Needed)
Where an inspection confirms that removal is necessary — or where a lender specifically requires it as a condition of lending — the next step is professional removal followed by an independent, RICS-verified removal certificate.
The certificate is issued by a RICS-qualified surveyor who inspects the property after foam removal and confirms in writing that:
- All spray foam has been removed
- The roof timbers are in an acceptable structural condition
- The property is suitable for normal mortgage valuation
This document is what your lender, conveyancer, or equity-release provider needs to proceed. A self-removal or uncertified removal will not satisfy lender requirements.

How Spray Foam Affects Selling, Remortgaging, and Equity Release
The practical impact depends on what you are trying to do. The sections below cover each situation separately.
Selling Your Home
If a buyer’s mortgage lender will not lend on the property in its current condition, the sale cannot complete — regardless of whether the buyer themselves is willing to proceed. This is one of the most common ways homeowners discover their spray foam is a problem: a sale agreed in principle collapses at the survey or valuation stage.
Your options when selling are broadly: commission an inspection to see whether the property is acceptable to lenders as it stands; arrange removal and obtain a certificate before relisting; or sell to a cash buyer who is not subject to mortgage lender requirements (though cash buyers typically factor the cost of removal into their offer price). Read more about spray foam problems that arise during the sales process.
Remortgaging
If you are coming to the end of a fixed-rate deal and want to switch to a new lender — or if you want to release equity by increasing your mortgage — the new lender will carry out a valuation. If their surveyor identifies spray foam, they may decline the application or require supporting documentation.
Remortgaging with your existing lender (a product transfer) may be easier in some cases, as some lenders are more flexible for existing customers than for new applicants. As of June 2026, based on the HomeOwners Alliance / BBC lender survey, TSB will not approve new mortgages on spray foam properties but assesses existing TSB mortgage holders on a case-by-case basis with supporting documentation. Always verify current policy directly with your lender or through a qualified broker.
Equity Release
This is the situation where we urge particular care and patience, because the financial and personal stakes are often highest. Equity release is typically sought by older homeowners who have paid off or nearly paid off their mortgage and wish to access the value tied up in their home.
As of June 2026, all equity-release providers surveyed by the HomeOwners Alliance refused to lend on properties with spray foam insulation. This means that an equity-release application may be declined even if the property is otherwise suitable and the homeowner has lived there for decades without any structural concerns.
If you or a family member is in this position, please do not feel rushed. An inspection is the right first step, and we can manage the process at a pace that suits you. Contact us or get a quote and we will explain your options clearly and without pressure.
This is general information, not financial advice. Equity release is a significant financial decision. Please consult a qualified financial adviser who specialises in equity release before proceeding.
Is the Government Helping?
The short answer is: partially, and not with funding for removal.
The government confirmed in March 2025 that it would not provide funding to help homeowners remove spray foam insulation. This applies even where the foam was installed under a government-backed scheme such as the Green Homes Grant. The Great British Insulation Scheme (GBIS) closed to new applications on 31 March 2026. Some other support schemes continue: ECO4 runs to December 2026 (benefits-led eligibility), and the Warm Homes: Local Grant runs to 2028 — but none of these funds spray foam removal.
What the government is doing is engaging with mortgage lenders to encourage them to take a more flexible approach to properties with spray foam. A number of parliamentary questions and debates have addressed the issue, and the House of Commons Library has published briefings tracking the position. However, as of June 2026, that engagement has not produced a consistent or lender-wide change in policy.
Some local authorities offer discretionary assistance or signposting to residents in financial difficulty — it is worth contacting your local council directly to ask what, if anything, is available in your area.
The practical position for most homeowners remains: the cost of inspection and, where necessary, removal falls to the property owner.
Lender Positions: What We Know as of June 2026
Lender policies change, and the position below reflects what has been reported and verified as of June 2026, based on the HomeOwners Alliance / BBC lender survey and House of Commons Library briefings. Always confirm current policy directly with your lender or through a qualified mortgage broker — do not rely on this page alone when making a financial decision.
| Status | What It Means |
|---|---|
| Refuse | Lender will not lend on properties with spray foam, regardless of type or condition |
| Case-by-case | Lender may consider applications with a PCA inspection report or removal certificate |
| Equity release | All surveyed equity-release providers refuse |
As of June 2026, over 50 UK mortgage lenders restrict lending on spray foam properties. Approximately 75% of providers surveyed refuse outright or assess case-by-case. TSB will not approve new mortgage applications on affected properties; existing TSB customers may apply case-by-case with supporting paperwork.

What to Do Next: A Clear Step-by-Step Plan
If you are facing a mortgage problem because of spray foam insulation, here is the most sensible sequence of steps.
- Don’t panic, and don’t book removal yet. Removal is not always necessary and should not be your first move.
- Get an independent inspection under the PCA Spray Foam Inspection Protocol. This tells you what type of foam you have, the condition of your timbers, and whether removal is genuinely required. Book an inspection.
- Share the inspection report with your mortgage broker or lender. In some cases this is sufficient for a case-by-case lender to proceed. Ask your broker to contact lenders who are known to consider applications with supporting documentation.
- If removal is recommended or required, book through a vetted specialist and ensure a RICS-verified certificate will be issued on completion. Read about our removal service.
- Present the certificate to your lender, conveyancer, or equity-release provider. This is the standard document they need to proceed.
- Consider re-insulation. Once foam is removed, your loft will need insulation to maintain energy efficiency and meet building regulations. We can arrange re-insulation with a lender-compliant product as part of the same project. See spray foam alternatives.
