Who We Work With

Utility Providers.

You have obligation targets to hit. We have the team, the accreditations and the track record to deliver the measures on the ground. One installer, full compliance, audit-ready every time.

We deliver the measures. You hit the targets.

Finding installers who can deliver at volume without causing compliance headaches is harder than it should be. Missed lodgements, inconsistent documentation, failed audits — it all comes back on you. We take a different approach.

When you sub work to Three Phase, you get one company handling assessment, coordination and installation. Our Retrofit Assessors survey the properties, our Coordinators manage the programme, and our own installers carry out the Solar PV, heat pumps, storage heaters, insulation and all associated electrical works. Every job is photographed, evidenced and lodged through TrustMark before we move on.

We have been through the Ofgem audit process. We know what they look for, we know how the documentation needs to be structured, and we make sure it is right before it leaves our hands. Your compliance team should not be spending their time chasing paperwork from the field — that is our job.

We are not a broker or a managing agent farming work out to whoever is available. We are the people who actually turn up, do the work and lodge it. That is a simpler relationship and it means there is one company accountable for the quality and the compliance behind every measure.

We delivered extensively under ECO4 and have a strong track record through the CHiL framework in Lancashire with 731 measures installed. As the obligation landscape evolves, we are positioned and ready to deliver under whatever comes next. The accreditations are current, the team is in place, and we are actively looking for utility partners who need reliable delivery on the ground.

Why utility providers work with us.

We have delivered thousands of funded measures across multiple programmes. Here is what that experience means for your obligation delivery.

Audit-ready documentation

Every installation is photographed, documented and lodged through TrustMark before we move on. When Ofgem comes knocking, the paperwork is already where it needs to be. No chasing, no gaps, no surprises.

One installer, not a supply chain

We are not a managing agent subbing work out to whoever picks up the phone. We are the assessors, the coordinators and the installers. One company, one point of accountability. That is a cleaner relationship and a lower risk profile for your programme.

Geographic reach

From Scotland to Penzance. We deliver in areas that other installers find difficult — off-gas properties, island communities, rural locations. We handle the logistics so the measures still get installed to the same standard wherever they are.

Volume without cutting corners

731 measures through CHiL, extensive ECO4 delivery, and a team structured to scale when a programme needs it. We know how to ramp up without the quality dropping off. Your obligation targets are met and the compliance holds up under scrutiny.

Every measure, fully accredited.

Whatever the obligation requires, we can install it. Solar PV, heat pumps, storage heaters, insulation and all associated electrical works. Every measure is carried out by our own qualified people, not passed on to a third party.

We hold MCS certification for Solar PV and heat pumps, NICEIC approval for all electrical works, and PAS 2035 qualification for retrofit assessment and coordination. ISO 9001, 27001 and 45001 certifications are current and independently audited.

That means when your compliance team checks our credentials against the programme requirements, everything stacks up first time.
