You can sell a house with spray foam, but the buyer's surveyor and lender may ask about it. Find the installation paperwork, answer the property information form truthfully[1], and consider independent evidence before you list. Don't rush into removal: Trading Standards advises getting an independent report first, because removal may be unnecessary[2].

Step by step
Spray foam handover pack checklist
The documents a spray foam installation should come with, according to industry guidance and product approvals. Tick what you have; print or save the list to take to the installer, your conveyancer or a surveyor.
0 of 15 documents ticked
If something is missing
- Ask the installer first. If it has ceased trading, ask the product manufacturer or the Insulation Manufacturers Association whether a pack can be obtained.

- A survey or condensation risk assessment produced after the work can't show the roof's condition before the foam went in, even if one is supplied retrospectively.
Based on: Insulation Manufacturers Association (Oct 2024) (opens in a new tab)
- Under the PCA inspection protocol, a missing or incomplete pack, or one not made at the time, can lead a surveyor to conclude there is “insufficient information”, and the protocol then points to further steps, such as a specialist survey.

- A complete pack doesn't prove the installation matches it: a product approval covers only work carried out as the approval describes.

- If there is no pack, the industry consumer guide suggests a specialist surveyor inspects for defects or departures from standards and manufacturer guidance. An independent inspection records what can be seen and tested; the foam hides the rest.

Find the installation paperwork
Gather the contract, product approval, condensation calculations, photographs, moisture readings and warranty, and ask the installer or manufacturer for anything missing[6]. If no pack exists, the joint industry consumer guide suggests a specialist surveyor to check for defects or departures from standards and manufacturer guidance[7]. What paperwork spray foam should come with
Answer the property information form truthfully
Tell your conveyancer about the foam and answer the TA6 (the seller's property information form) accurately, attaching the paperwork you have; question 5.1(h) asks about insulation works and 6.1(h) about insulation warranties[8]. The Law Society says a buyer given misleading information "may be able to claim compensation" after completion[1]. Selling with spray foam: what to tell buyers
Expect questions from the buyer's lender
Some lenders ask for specific evidence: Nationwide's valuer reconsiders on a pre-installation survey report, a condensation risk assessment, BBA approval evidence and a transferable warranty, or, if the foam is over two years old, an invasive inspection by an MRICS/FRICS chartered building surveyor (criteria as published in 2026)[9]. Have your documents ready before the buyer's survey. What mortgage lenders publish
Get independent evidence before you list
An inspection before the buyer's survey shows you what can be seen and tested, and gives you time to plan, as in Checked before listing: water ingress indicated at the rear slope, and a rotted purlin. The industry consumer guide advises choosing someone free of commercial interest, or who declares it[7]. Selling: your options
Don't rush into removal
RICS says removal can damage the structure the foam was sprayed onto[6], and Trading Standards advises an independent report first because removal may be unnecessary[2]. Don't let a buyer's deadline skip that step. Do you need to remove spray foam?
If you remove it, keep the evidence
Keep before-and-after photographs, the removal firm's invoice and method, and an independent check of the timbers, underlay and ventilation. Legal & General's later-life criteria (page dated 23 Jun 2026) ask for residue cleared, a roof report by a structural engineer or chartered surveyor, repairs and building control sign-off[5]. After spray foam removal
What to do next
- Tell your estate agent and conveyancer about the foam early.
- If removal comes up, get independent evidence first and compare more than one quote.
- An independent inspection is evidence for your own decision: keep, remove or adjust the price. It is not a report for a lender, and no one can promise what a buyer's lender will do.
- If you want independent evidence of what is in your loft before you list, see the inspection below.
Get an independent record of the loft before you list
A pre-sale inspection gives you photographed evidence of the loft before buyers ask, so you can decide whether to keep the foam, remove it or adjust the price.
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's yours to use as you choose. It doesn't predict what a buyer's lender will decide.

Questions people ask
Do I have to tell buyers about spray foam?
The Law Society says sellers must answer the TA6 truthfully, and that a buyer given misleading information may be able to claim compensation after completion[1]. Ask your conveyancer how the foam and its paperwork should be described on the form. This is general information, not legal advice.
Should I remove spray foam before selling?
Not automatically. The government has said an installation meeting scheme standards would not be expected to need removal or to prevent a mortgage[10]. Trading Standards advises an independent report before agreeing to removal[2], and at least one lender, Accord, lists removed foam as unacceptable (checked 20 Oct 2026)[4].
Will spray foam stop my buyer getting a mortgage?
It can with some lenders. In the BBC's November 2024 survey, five of the 20 largest lenders would not lend and most decided case by case[3]. Have the installation paperwork ready before the buyer's survey. No one can promise what a buyer's lender will decide.
