Leeds Building Society and spray foam insulation
Our contractors: 15,123 verified reviews across 8 platforms, rated 4.9 on GoogleLeeds Building Society is reported to decline mortgage applications on properties with spray foam insulation in the roof, largely without reference to the foam's condition. Last verified September 2026, and worth checking directly with a broker before you make any decision around it.
Leeds Building Society's reported position
Trade press and broker sources place Leeds Building Society among the lenders reported to refuse spray foam cases outright, consistent with the BBC's November 2024 survey of major UK providers, which found around a quarter would not lend on a foamed roof at all. Leeds has not published its own spray foam criteria, so this is a reported position, last verified September 2026.
What this means for you
As one of the larger regional building societies, Leeds is reported to run a conservative underwriting book, and spray foam is one of a small number of building types and features treated as an automatic exclusion rather than referred to a specialist surveyor. That makes the usual first move, commissioning an inspection report, less likely to change the outcome with this particular lender than with several others.
The inspection is still worth having regardless, because it tells you what you are actually dealing with. A roof that turns out to be sound is good news whichever lender ends up on the mortgage, and a roof with a real defect needs addressing whatever anyone's policy says.
This is not Leeds Building Society's published policy. No lender in this market publishes its spray foam criteria, so treat this as a reported starting point, last verified September 2026, and have a broker confirm the current position before you rely on it.
What to do next
The three routes, weighted for a lender in this group.
- Inspect first, always. Free, and around two thirds of the lofts inspected by the Property Care Association had no defect at all.
- Remove and document if the foam has to go, so the evidence works for any lender the mortgage eventually sits with.
- Talk to a broker about a lender assessing case by case. With Leeds reported to decline this consistently, moving the mortgage is generally quicker than trying to change one lender's underwriting rule.
No obligation, no deposit
Get the loft looked at properly
Whatever your lender's position, the starting point is the same: know what is actually up there. An inspection gives you a written verdict and photographs, and if the foam is sound that is what the report says.

Two steps. No deposit, and nothing to pay if the foam is sound.
Leeds Building Society and spray foam, common questions
Does Leeds Building Society treat open cell and closed cell foam differently?
Not according to reported experience. A blanket-refuse position like this one is described as applying regardless of foam type, which is the main thing separating it from a case-by-case lender's assessment.
Will Leeds reconsider once the property has been re-insulated?
Re-insulation on its own does not address the underlying reason for refusal, which is reported to be the presence or history of spray foam rather than the current insulation standard. Documented full removal is the more relevant evidence, if evidence is going to help at all with this lender.
Is there a route to appeal Leeds Building Society's decision?
Ask your broker whether an appeal is realistic in your specific case; broker experience with blanket-refuse lenders generally does not report much success. Moving the application to a case-by-case lender is usually the more productive use of time.
How current is this information on Leeds Building Society?
Last verified September 2026, from press reporting and broker sources, not from Leeds Building Society's own published criteria. Positions in this market move without announcement, so confirm it again before you act.
Does Leeds Building Society's stance differ for a second home or holiday let?
Reported experience does not draw a clear distinction. Brokers describe the exclusion applying wherever spray foam is identified in the roof, regardless of whether the property is a main residence, a second home or a holiday let.
