We train our teams to meet TrustMark’s technical standards on every grant job. Private homes get the same standard, plus the design, finish and attention to detail their owners expect.

Who checks our work
Each home is surveyed and designed first, then signed off before the scaffold comes down.
ROCKWOOL Wall Systems reviews photos of every stage before issuing the materials guarantee.
Cotality, our independent retrofit coordinator, signs off every grant job against PAS 2035.
The BBA and the Installation Assurance Authority inspect a sample of our jobs on site.
Grant jobs are lodged with TrustMark, which can inspect any of them once the work is finished.
Every inspection moves our training forward.
Our record
Our grant-funded jobs are lodged with TrustMark, the government-endorsed quality scheme, and TrustMark can inspect them once finished. On ECO4, TrustMark aimed to inspect every job.
Across more than 500 lodged jobs, the record stands at zero remediations required. In 2025, TrustMark removed a number of insulation installers from its register for poor quality. We were not among them.

TrustMark registered
External wall insulation since 2012. Today, nine TrustMark registered measures. Planned together, they work as one.

Roofs
And more
We do it all from one scaffold, so the job is done once. One scaffold, one mess, one tidy-up, and every measure planned to work with the next.
Every job starts with a plan. We survey the house, we design the work, and we follow PAS 2035. On grant work, we follow it to the letter. On private work, we follow its principles.
What it means for your home
Our certification bodies inspect a sample of our jobs, during or after the work, against their own standards.
Up to 25 year insurance backed guarantee from SWIGA or the IAA, plus the ROCKWOOL materials guarantee.
Grant or private, every home gets a trained Pioneer team and the same standard of work.
