Who Can Claim Compensation?

You Can Claim If:

  • Insulation was installed in the last 10 years (some claims go back further)
  • You have damp, mould, or structural damage caused by the insulation
  • Installation was under ECO, GBIS, Green Deal, or similar government scheme
  • You have an insurance-backed guarantee (CIGA, Trustmark, etc.)
  • Spray foam has affected your mortgage application or home sale
  • Installation breached building regulations or industry standards
  • You weren't informed of risks before installation

Claims Are Harder If:

  • Installation was over 15 years ago (limitation periods apply)
  • You have no paperwork (installer name, guarantee certificate, etc.)
  • The installer is dissolved and there's no insurance-backed guarantee
  • Damp problems existed before the insulation was installed
  • You can't prove the insulation caused the damage (need professional survey)

Don't worry if some of these apply - many claims succeed despite these challenges. We can advise on your specific situation.

5 Ways to Claim Compensation

1

Direct Claim Against Installer

The first and simplest route. Contact the company that installed your insulation and request they rectify the defects or compensate you for the damage.

Best for:

  • • Installer still trading
  • • Recent installations (within 1-2 years)
  • • Clear installation defects

Success rate: 35%

Many installers ignore complaints or have ceased trading to avoid liability.

2

CIGA Guarantee Claim

The Cavity Insulation Guarantee Agency (CIGA) provides 25-year insurance-backed guarantees for cavity wall insulation. If your installer provided a CIGA certificate, you can claim directly from CIGA.

Best for:

  • • Cavity wall insulation issues
  • • You have a CIGA certificate
  • • Installer ceased trading

Success rate: 72%

CIGA covers extraction and making good. Average payout: £3,000-£12,000.

3

Trustmark Complaint

Trustmark-registered installers must rectify defects or face losing their endorsement. File a complaint through Trustmark's dispute resolution process.

Best for:

  • • Trustmark-registered installers
  • • Government scheme installations
  • • Installer ignoring direct complaints

Success rate: 58%

Trustmark can force installers to rectify work or compensate. Process takes 4-12 weeks.

4

Energy Company Claim (ECO/GBIS)

If your insulation was funded by ECO4, GBIS, or similar schemes, the energy company that funded the work has ongoing liability for quality standards.

Best for:

  • • ECO4 or GBIS installations
  • • Installation failed quality checks
  • • Installer defunct

Success rate: 45%

Energy companies resist claims but NAO Report has increased pressure. Expect 3-6 months.

5

Legal Action (No Win, No Fee)

Pursue compensation through specialist solicitors on a no-win-no-fee basis. They'll claim against installers, their insurers, or pursue group actions.

Best for:

  • • High-value claims (£10,000+)
  • • Other routes exhausted
  • • Serious health/structural damage
  • • Multiple affected properties (group claims)

Success rate: 94%

Highest success rate but longer timescales (6-18 months). Average payout: £15,000-£45,000.

Evidence You Need for a Strong Claim

Installation Documents

  • • Installer name and contact details
  • • Installation date
  • • Contract or quote
  • • CIGA/Trustmark certificate
  • • Government scheme paperwork
  • • Any correspondence with installer

Don't have these? We can help track down documents through government databases and industry registers.

Professional Survey

  • • RICS-certified surveyor report
  • • Moisture meter readings
  • • Thermal imaging evidence
  • • Photos of damage
  • • Link between insulation and damp
  • • Cost estimate for remediation

Essential: This is the single most important piece of evidence. Without it, most claims fail.

Supporting Evidence

  • • Photos of damp/mould (before & after insulation)
  • • Medical records (if health affected)
  • • Energy bills (showing no improvement)
  • • Mortgage refusal letter
  • • Remediation quotes
  • • Timeline of events

Tip: Document everything with dates. Create a folder with all evidence.
