TrustMark saves energy with Stroma

This approval will enable members to apply for TrustMark status so that they can be found by homeowners using the TrustMark postcode search facility. Already this year, just under five million search results were provided to homeowners who used TrustMark’s website and telephone helpline to find expert tradespeople. 

All Stroma Certification installer members who qualify will be able to carry the TrustMark badge to give further protection and reassurance to their customers. This opens up a fresh advertisement channel for Stroma-certified installers and an opportunity to promote their installation services to a captive audience.

Andy Sharp, commercial manager of Stroma Certification, said: ‘Becoming a TrustMark Scheme Operator is a huge endorsement for us and it is a badge that our installers can show the customer, proving that they have been properly assessed and inspected and will work to government-endorsed standards.’

Simon Ayers, chief executive of TrustMark, said: ‘Stroma Certification put in an excellent application which the Board was pleased to approve and it has demonstrated a readiness to embrace the high standards and responsibilities we expect of all scheme operators.’

The TrustMark scheme operator license was awarded to Stroma Certification in July 2015 following a thorough assessment of all its processes for vetting and inspecting installers as well as its customer service policies, compliance audits, quality management and complaint handling procedures.
