The unanswered questions manufacturers don’t want homeowners to ask

Over the past decade, spray foam insulation was marketed as a miracle energy-saving upgrade. It was sold under trusted names — Icynene, Lapolla, Isothane, Huntsman Building Products, BASF — through an expanding network of UK dealers and installers.

By March 2024, the Royal Institution of Chartered Surveyors (RICS) made its stance clear: any property containing spray foam insulation automatically fails a mortgage survey, regardless of paperwork or certification. For thousands of homeowners, sale chains collapsed, remortgages stalled, and equity release was blocked — with the only realistic way forward being spray foam removal by a reputable, documented specialist.

Manufacturers’ responsibility — where were the safeguards?

Each major manufacturer published technical guidance on safe application, ventilation, and moisture control. On paper, those safeguards should have protected homeowners. In reality, installations routinely breached building regulations, trapped moisture, and covered roof timbers that surveyors could no longer inspect.

The distribution model — profits before protection

Spray foam was largely distributed via independent companies who trained, “certified,” and monitored their own installers. The same firm could sell the product, teach the installer, and approve the work. With minimal external oversight, accountability vanished — and poor-quality installations spread nationwide.

Did the manufacturers know?

It’s difficult to believe multinationals were unaware of widespread misuse. Warning signs mounted: failed surveys, damp and mould complaints, and aggressive cold-calling that claimed foam was “lender approved.” Those claims weren’t true — yet the machine carried on.

Building regulations were clear — so why were they ignored?

UK Building Regulations Part L and Part C require roofs to remain ventilated and free from trapped moisture. Many applications — especially open-cell foam sprayed onto non-breathable felt — breached those principles outright. Roofs couldn’t breathe; moisture became trapped; rot developed unseen behind the foam.

Testing, oversight, and the data problem

When challenged, manufacturers often cited American test data that didn’t reflect UK construction or climate. No independent UK scheme verified consistent installation quality, and many warranties proved worthless once a distributor or installer ceased trading. Homeowners were left with no mortgage, no redress, and no clear route to compensation.

Where is the accountability?

Despite thousands of affected properties, there have been no public investigations or penalties issued to manufacturers or distributors. No recall. No inquiry. No responsibility accepted.

Government inaction — the missing response

As of 2025, there is no compensation scheme and no dedicated oversight. The Department for Levelling Up, Housing and Communities has not launched an inquiry. Homeowners are funding removals themselves — often running into several thousands depending on roof size and foam type.

History repeating — the rise of cowboy removal firms

Many of the same companies that installed spray foam have rebranded as “removal experts,” using the same cold-calling tactics. They scrape off surface foam, leave residue, dispose of waste improperly, and provide no valid documentation — leading to failed re-surveys and double costs for homeowners.

How homeowners can protect themselves

  • Never engage with cold callers.
  • Check VAT registration and a verifiable business address.
  • Request a waste carrier’s licence for legal disposal.
  • Ask for a written quotation and method statement.
  • Request photographic before-and-after proof.
  • Ensure the contractor issues RICS-compliant documentation on completion.

The right way forward: a legitimate process includes product identification, controlled extraction, residue removal, ventilation restoration, licensed waste disposal, and a completion pack. This is what lenders expect to see for RICS-compliant removal.

The moral question — why have manufacturers gone unpunished?

Guidelines were issued, distributors trained installers, and sales scaled — but when the failures surfaced, no one at the top accepted responsibility. Homeowners deserve answers. A government-led inquiry is long overdue.

Learning from the past — preventing the next crisis

Future energy-efficiency schemes must embed independent auditing, certified training, and transparent documentation. Without real accountability, history will repeat — and homeowners will pay the price.

If your home contains spray foam insulation or you’ve been contacted by a removal company, get independent advice before you act. Our team provides clear written quotations, photographic evidence, and full documentation to restore survey-ready status.
