Spray foam isn’t just causing problems in your loft — it’s blocking home sales across the UK.
Over the past year, more and more estate agents have been raising concerns about spray foam insulation. What used to be considered a clever energy-saving upgrade is now becoming one of the most common dealbreakers in the UK housing market.
So, what’s going on?
And why are estate agents urging sellers and buyers alike to think twice?
🚫 Sales Falling Through at Survey Stage
When a home goes on the market, one of the first hurdles is the mortgage valuation. Lenders send out surveyors to ensure the property meets lending criteria — and spray foam insulation in the loft is now a major red flag.
In many cases, lenders are:
- Flatly refusing to lend on spray foam-insulated homes
- Demanding costly removal before offering approval
- Withdrawing mortgage offers mid-sale
This puts estate agents in a tricky position — they can list the property, but they can’t guarantee any sale will go through.
🏡 Buyers Are Backing Out
Even cash buyers are growing wary.
Buyers are being advised to steer clear of spray foam altogether due to concerns about:
- Long-term structural damage
- Hidden roof ventilation issues
- Future difficulties when they want to sell
For estate agents, this means fewer viewings, longer time on the market, and frustrated clients stuck in property limbo.
🧊 It's Chilling the Market
Homes with spray foam insulation are increasingly being:
- Downvalued
- Removed from portals
- Delayed or cancelled mid-sale
And some estate agents are now outright refusing to list properties with spray foam in the loft unless the seller has a removal plan in place.
It’s not just about energy savings anymore — it’s about marketability and risk.
🧠 Estate Agents Are Noticing a Pattern
Most agents we speak to say the same thing: the problems caused by spray foam insulation are becoming too common to ignore.
Sellers are often unaware that their insulation is the reason they’ve had no offers. Some are even blindsided at the point of sale when a buyer’s survey flags it as a serious issue.
In short: the foam you were told would add value may now be doing the opposite.
