    1. 1.Did they contact you out of the blue, by phone or at your door?

      Why ask this?

      Citizens Advice says not to use a company that cold calls, and the HomeOwners Alliance says callers may have got your details unlawfully or be linked to the original installer.

      Based on: Citizens Advice (England; reviewed 4 Apr 2025) (opens in a new tab); HomeOwners Alliance (undated) (opens in a new tab)

    2. 2.Did they say they were from, or working with, the government, a council, Trading Standards or an official scheme, or that a grant would pay?

      Why ask this?

      Trading Standards services have warned about callers falsely claiming to act for the government or an official scheme, and about false claims that a grant would cover the cost.

      Based on: Local Trading Standards services (Plymouth City Council and others; various dates) (opens in a new tab); Warwickshire County Council Trading Standards (5 Feb 2025) (opens in a new tab); Trading Standards Scotland (17 Sep 2024; modified 2 Apr 2025) (opens in a new tab)

    3. 3.Did they say they were from the Property Care Association (PCA), or show ID or a report with the PCA's name or logo?

      Why ask this?

      The PCA has warned of fake ID with its logo and fake reports in its members' names, and says it has no in-house surveyors.

      Based on: Property Care Association (29–30 Jul 2026, as carried by The Intermediary and News on the Block) (opens in a new tab); House of Commons Library (published 5 Jan 2026; page metadata modified 8 Jul 2026) (opens in a new tab)

    4. 4.Did they say your home is on a “national database”, or will lose value unless the foam comes out?

      Why ask this?

      The PCA reported fraudsters telling homeowners their property was on a “national database” of homes likely to lose value unless the foam was taken out.

      Based on: Property Care Association (29–30 Jul 2026, as carried by The Intermediary and News on the Block) (opens in a new tab)

    5. 5.Did they offer a free survey or inspection of your loft or your foam?

      Why ask this?

      Trading Standards has warned about cold callers offering free loft surveys and then finding problems that foam, or its removal, would supposedly fix.

      Based on: Trading Standards Scotland (21 Oct 2022) (opens in a new tab); Citizens Advice (Jun 2025; web page 17 Jun 2025) (opens in a new tab)

    6. 6.Did they say your foam must come out, or is damaging your home, before anyone had properly looked at it?

      Why ask this?

      Trading Standards has reported scare stories used to sell removal, and Citizens Advice has seen removal sold where it wasn't needed, even to homes with no foam.

    7. 7.Did they push you to decide today, or offer a price that only lasts today?

      Based on: Citizens Advice (6 Dec 2021) (opens in a new tab); Energy Saving Trust (updated 8 May 2026) (opens in a new tab)

    8. 8.Did they ask for money upfront, a large deposit, or your bank or card details?

      The Energy Saving Trust says not to pay everything upfront, and Citizens Advice suggests a deposit of no more than 25%.

      Based on: Energy Saving Trust (published 12 Mar 2019; updated 20 May 2026) (opens in a new tab); Citizens Advice (England; reviewed 4 Apr 2025) (opens in a new tab)

    9. 9.Did they say you are owed compensation, or offer to make a claim for you?

      Why ask this?

      The HomeOwners Alliance and the PCA have reported owners being targeted by legal firms pursuing mis-selling claims, as well as by removal firms.

      Based on: HomeOwners Alliance and Property Care Association (10 Feb 2025) (opens in a new tab)

    10. 10.Did they mention a lung or health charity, or say your existing insulation is harmful to health?

      Why ask this?

      Asthma + Lung UK says cold callers have falsely claimed to represent it; it endorses no insulation product and has never said any insulation material is unsafe.

    What best describes your situation?

    The 10 most-asked questions

    Can I get a mortgage on a house with spray foam?

    It depends on the lender: a BBC survey of the 20 largest (November 2024) found five would not lend and five decided case by case[1]; the government says foam alone should not automatically prevent lending[2].

    How do I know if I have spray foam?

    Look from the loft hatch with a torch; the Commons Library describes open-cell foam as soft and closed-cell as rigid[3].

    Read more: Identifying spray foam

    Do I need to remove it?

    Not necessarily: in June 2025 the government said foam installed to scheme standards would not be expected to need removal, as surveyors can apply a published inspection protocol[4]. Warwickshire Trading Standards advises an independent survey first[5].

    Read more: Removal explained

    How much does spray foam removal cost?

    No reliable dataset exists: the most-quoted guide price (a trade directory, July 2026) is AI-generated, and Citizens Advice (June 2025, from consumer service cases) reports some removals costing tens of thousands of pounds[6][7].

    Read more: Removal and costs

    Is there a "removal certificate"?

    No official one exists, and lenders differ on removed foam: Nationwide's criteria are silent on it[8], while Accord's criteria (checked 20 October 2026) list homes where foam was used and later removed as unacceptable[9].

    Does spray foam rot roof timbers?

    It depends how it was applied: the regulator's modelling found low moisture risk for open-cell foam installed to BS 5250:2021 (the British Standard on moisture) but high risk for foam sprayed directly onto tiles or slates, and stresses this is theoretical[10][11].

    Should I buy a house with spray foam?

    Find out more first: RICS says a foam-covered roof structure cannot be fully seen or inspected, and that spray foam may affect a surveyor's opinion of value[12].

    Read more: Buying with spray foam

    Can I claim under Section 75?

    Possibly, if you paid by credit card or certain finance: section 75 can make the lender equally liable with the supplier for misrepresentation or breach[13]. In a 2025 decision a lender could doubt a report from the firm that then removed the foam[14].

    Read more: Section 75 claims

    Someone called saying my foam must come out. Is it a scam?

    It may be: Devon, Somerset and Torbay Trading Standards reported a "steep rise" in removal cold-call complaints, and in July 2026 the PCA (Property Care Association) warned of callers with fake PCA ID citing a "national database"[15][16].

    Is there a grant to remove spray foam?

    Not from the government: it said in March 2025 that "There are no government schemes to support private homeowners" to pay for removal[17]. The Warm Homes Plan (January 2026) does not mention spray foam, and the Great British Insulation Scheme closed on 31 March 2026[18][19].

    How this guide is written

    SprayFoamCheck inspects lofts and writes reports. It does not install or remove insulation, and has no referral arrangements with installers, removal firms or claims firms; none is named, ranked or recommended here.

    Every fact links to its source, and anything that can change carries its date. Ombudsman decisions are examples, not predictions, and nothing here is legal, financial or lending advice.

    Pages show review dates. To report an error, use the contact details on the About page.

    Your next step

    Get facts about your own loft

    This guide explains what the evidence says in general. An independent inspection records what is in your loft: the foam type where it can be identified, what it is sprayed onto, coverage and defects, and moisture readings at points that can be reached, with photos.

    Spray Foam Inspection£295

    Report within 48–72 hours of inspection. Independent: no installation, no removal, no referral commissions.

    Travel included within about three hours of the North West; a fixed supplement further away, shown with your total before you book.

    It records what can be seen and measured. It can't see timber under the foam, and it isn't a report for a lender.
