Real Protection, Not Badges
LAMTANS Engineering Ltd holds recognised industry accreditations covering quality, safety and consumer protection. These accreditations are not just badges on a wall — they are what stand behind your project.
Choose Carefully
Hiring an unaccredited contractor can lead to poor workmanship, a lack of financial protection and no formal dispute resolution if issues arise after completion. Unregulated work may also fail to meet government scheme requirements such as ECO4 or Warm Homes Plan standards, resulting in rejected applications or additional costs for homeowners.
Our Credentials
Every credential below is one you can rely on and verify. Together they cover workmanship quality, retrofit best practice, renewables consumer protection and government grant-scheme eligibility.
TrustMark is the government-endorsed quality scheme for home energy improvements. All ECO4 insulation measures must be installed by TrustMark-registered businesses. As a registered installer, we commit to:
PAS2035 is the British standard for the retrofit of domestic properties. It is required for ECO4 insulation work and represents best practice for any insulation project. As a compliant installer, we commit to:
RECC is the consumer protection code for renewable energy installations including solar panels, battery storage and heat pumps. As a RECC-accredited installer, we comply with RECC consumer protection standards:
Because we are TrustMark registered and work to PAS2035, LAMTANS is eligible to deliver ECO4-funded insulation and heating measures — government grant schemes require exactly these credentials. Renewable installations that access grants such as the Boiler Upgrade Scheme are carried out to the required UK certification standards, so your project qualifies.

Common Questions
Yes. LAMTANS is RECC accredited, the consumer protection code for renewable energy installations. Grant-funded solar and heat pump work — such as the Boiler Upgrade Scheme — is carried out to the required UK certification standards, so your project qualifies and meets the necessary quality and consumer-protection requirements.
RECC accreditation means transparent pricing, no high-pressure selling, written contracts, a 14-day cooling-off period and access to independent dispute resolution — so your renewable energy project is fully consumer-protected.
