What should you ask before spray foam comes off?
In Cheshire, spray foam on the underside of a roof should be looked at by a specialist surveyor before you agree a removal. No price is printed for taking foam out of a loft, a roof or an attic.
Last reviewed:Look before anyone prices the foam
Spray foam is a liquid insulation that expands and sets into a firmer layer, and it is used in roofs, lofts and attics [S1]. In Cheshire, people are being offered removal after a cold call or a survey flag, sometimes before anyone has said the foam should come off. You can often see it yourself: a solid layer across the underside of the roof [S1]. Seeing it is not the same as deciding it has to go.
GOV.UK says spray foam can be used effectively in many settings, and also that it is not always the right product for some homes and may need to be fixed or removed [S1]. Before any decision, take advice from a specialist surveyor [S1]. Only specialist surveyors experienced in spray foam application can tell you if the foam should be removed [S1]. You can find a specialist through the Property Care Association [S1]. That body is named from the GOV.UK sentence. No finder tool is linked.
Read the GOV.UK page itself if you are about to sign a removal contract. The questions below are what to ask. They are not a method for scraping foam, and no price is printed. No removal figure appears on the GOV.UK page used here.
The survey comes before the contractor
Make sure the surveyor knows the Spray Foam Insulation Inspection Protocol of March 2023 [S1]. Ask them to say, in writing, whether the foam should stay, should be repaired, or should be removed, and what they saw: which slopes, how thick it looks, and whether the roof covering or the timbers are part of their comment. If they will not separate "remove" from "leave", you do not yet have a decision you can price.
Discuss it with your lender as well [S1]. Removing the foam will not always mean they will still lend, and improper removal could lead to further issues [S1]. That sentence is why a cheap scrape is a poor saving. A removal quote that starts before the survey is a quote for a job you might be told not to do.
Many mortgage providers are open to lending on properties with spray foam, subject to their own requirements [S1]. GOV.UK publishes a list and says lenders can be added at any time [S1]. The list is not frozen, so the names are not copied. Open the page, and talk to the lender who is actually on your mortgage. Have the installation paperwork ready. If you do not have it, the installer or the manufacturer should be able to provide it afterwards [S1].
HSE: work at height. QuoteZila is not affiliated with this organisation.
The definition used above is the one on the HSE work at height FAQ [S2].
Reaching the foam is part of the job
Foam on the underside of a roof is above the loft floor or above a ceiling. HSE defines work at height as work in any place where, if precautions were not taken, a person could fall a distance liable to cause personal injury [S2]. You are working at height if you work above ground or floor level, or could fall from an edge, through an opening or a fragile surface, or into an opening in a floor or a hole in the ground [S2]. A slip on the level is not work at height, and neither is walking a permanent staircase [S2].
The Work at Height Regulations 2005 apply where there is a risk of a fall liable to cause personal injury [S2]. They place duties on employers and on those who control the activity, such as facilities managers or building owners who may contract others to work at height [S2]. If you are the householder hiring the firm, ask how the work will be planned, who is competent, and what equipment they will use. The duties include planning the work, using competent people, assessing the risks and choosing equipment, managing fragile surfaces, and inspecting and maintaining the equipment [S2].
Ladders are allowed only when a risk assessment has shown that equipment with a higher level of fall protection is not justified because of the low risk and short duration, or because existing features of the workplace cannot be altered [S2]. Short duration is not the deciding factor. The risk comes first. As a guide, if the task would require staying on a leaning ladder or a stepladder for more than 30 minutes at a time, HSE says consider alternative equipment [S2]. Use ladders only where they can be level and stable and, where reasonably practicable, secured [S2]. No method is set out for footing a ladder or for entering a loft. Ask the firm what they will use, and do not start the removal yourself.
If a scheme paid for the installation
All installations under government schemes since 2020 must be by TrustMark-registered installers [S1]. If you have found a problem, the installation was completed less than 6 years ago, and the installer is still trading, you can use the TrustMark dispute resolution process [S1]. The paperwork from the installation names the installer and the scheme provider. Contact them [S1]. If you do not know the scheme provider, GOV.UK says to search for the registered business on TrustMark's Find a Business page [S1]. If you still need a resolution after those contacts, contact the Dispute Resolution Ombudsman [S1]. Use the names on your paperwork and the route on the GOV.UK page.
If the installer is no longer trading, contact the insurance-backed guarantee provider [S1]. Check the details on the paperwork. Typically this may last up to 10 years [S1]. If the paperwork is missing, contact TrustMark to find that provider [S1].
If the insulation was installed before the 2020 TrustMark requirement for government schemes, check whether the original installer is still trading [S1]. If not, look at the paperwork for an insurance-backed guarantee or the name of a scheme, a certification body or a quality mark, and contact that organisation [S1].
Keep the dispute route and the removal quote apart. A firm that offers to "sort the lender" and remove the foam in one visit is asking you to skip the survey GOV.UK puts first.
Cold calls
The growth of spray foam removal has come with more cold calls and unsolicited offers to sell or remove it [S1]. You can report those to trading standards [S1]. If you believe an installer shared your details with a removal company, you can complain to the Information Commissioner's Office [S1]. A call that urges you to book this week, before a survey, is a reason to slow down, not a reason to post a job with no description.
What a removal quote is allowed to assume
Only price removal after a surveyor has said the foam should come off [S1]. Give every firm the same pack:
- The surveyor's written view, or a clear statement that you do not have one yet and you are pricing advice, not removal.
- Which roof slopes, and whether the foam is on the underside, in a loft, or in an attic room.
- Whether you live in the house during the work, and how the loft is reached.
- The paperwork: installer, scheme, date, and any insurance-backed guarantee.
- Whether the lender has already written to you, and what they asked for. Do not send them a removal contract as if it answered a valuation.
- Who takes the waste, and who makes the ceiling or the roof good if the work opens it. Improper removal can lead to further issues [S1]. Ask the firm to describe "proper" for this roof in writing.
Citizens Advice says a quote is a fixed price and an estimate is a rough guess that can rise [S3]. Ask for a fixed total for the slopes the surveyor named. The paper should break the work down, say whether VAT is included, and say how long the price lasts [S3]. Do not rely on a spoken figure [S3]. After you accept, the agreement can bind you even without writing, so write it [S3]. The firm should not add charges unless you asked for extra work, you agreed an extra, or there was a genuine pricing mistake [S3].
Try for at least three written quotes on that pack [S3]. A price a lot lower than the others may mean they are not quoting for the same work, or that they lack the skills or are not being honest [S3]. Ask whether waste, protection of the rooms below, and making good are on each paper. Some firms charge to quote. Ask before the visit [S3]. If they advertise no call-out charge, that claim is fair only when there is no fee for travel, for the first diagnosis, or for any other charge before you agree [S5].
If the work will take a long time and a deposit cannot be avoided, do not agree more than 25 per cent, and take a receipt [S3]. Ask to see insurance that covers damage to the building [S3]. VAT registration applies when taxable turnover for the last 12 months is over £90,000 [S4]. Ask whether your total includes it.

Jobs you might post
These are examples, not taken from real job posts.
- Loft in Crewe with a solid foam layer on the underside of the roof. Customer wants a specialist survey first, not a removal price. Household will not enter the loft for the survey.
- Survey already says the foam on the rear slope of a Nantwich house should be removed. Quote the removal of that slope only, including waste and how the firm reaches the work. Customer has the 2021 installation paperwork.
- Cold call offered to strip foam in Sandbach this week. Customer wants a written opinion from a specialist surveyor, and does not want removal booked.
Anyone in the UK can post or register. Name the town and say whether a survey exists. Do not describe a scraping method.

Questions about spray foam
Why is a single removal price not printed?
GOV.UK does not publish a price for taking spray foam out. A small patch and a whole roof slope are different jobs, and removal is not always the right step. A specialist surveyor has to say whether the foam should come off. Ask that question before you collect removal totals, or the totals are for a decision you have not made.
Who can say the foam should be removed?
Only specialist surveyors who are experienced in spray foam application can tell you if it should be removed. GOV.UK says to take that advice before any decision, and to find a specialist through the Property Care Association. Discuss the same question with your lender. A general description does not decide a particular roof.
Will the lender still lend if the foam is removed?
Not always. GOV.UK says removing the foam will not always mean a lender will still lend, and that taking it off badly can cause further problems. Many mortgage providers are open to lending on homes that still have spray foam, subject to their own requirements. The GOV.UK page keeps a list of lenders that can change. Check that page and speak to your lender. Do not treat any copied list as complete.
Is a loft visit work at height?
HSE says work at height is work where, if precautions were not taken, a person could fall a distance liable to cause injury. That includes work above floor level. It does not include a slip on the level or walking a permanent staircase. Employers, and people who control the activity, including a building owner who contracts others, have duties under the Work at Height Regulations 2005. Ask the firm how they will reach the foam. Do not climb to start the job yourself.
What if the install was under a government scheme?
Installations under government schemes since 2020 must be by TrustMark-registered installers. If there is a problem, the work was finished less than 6 years ago, and the installer is still trading, GOV.UK points you to the TrustMark dispute route, using the installer and scheme provider on your paperwork. If the installer has stopped trading, contact the insurance-backed guarantee provider. That cover may last up to 10 years. Check the paperwork.
