Who We Work With

Housing Associations.

Multi-measure energy upgrades across your housing stock. One company, one contract, one team looking after the whole process from the first survey to the final lodgement.

Upgrading housing stock without the headaches.

You know how this usually goes. You appoint a managing agent, they appoint an assessor, a coordinator and two or three different installers. Nobody is quite sure who is doing what, your tenants are getting conflicting information about when the work is happening, and six months in you are still chasing lodgement paperwork.

We take a different approach. When you appoint Three Phase, you get one company doing the assessment, the coordination and the installation. Our Retrofit Assessors survey the properties. Our Coordinators manage the programme. Our installers carry out the Solar PV, heat pumps, storage heaters, insulation and all the electrical works. One contract, one set of invoices, one person to ring.

That means your tenants see the same faces each week. They know who is coming, what is being done, and who to talk to if they have a question. It is a better experience for the householder and far less admin for your team.

We handle tenant liaison directly. Appointment scheduling, access arrangements, pre-install letters and aftercare. Your housing officers are not spending their days fielding calls about when the electrician is coming back, because our coordinator has already sorted it.

Everything is lodged through TrustMark before we move on. EPCs are updated, MCS certificates are issued, and all the compliance documentation is packaged and handed over. When your board or your funder asks for an update, the paperwork is already there.

We know what housing associations need.

We have worked with housing associations long enough to know what keeps asset managers up at night. Here is how we address each one.

Tenant experience

Same team each visit. Pre-install communication handled by us. Appointment scheduling, access coordination and aftercare all managed by our coordinator, not dumped back on your housing officers.

Compliance and audit

PAS 2035 throughout. TrustMark lodgement on every property. MCS certification. EPC updates. All documentation packaged and handed over, not drip-fed months after the work is done.

Programme delivery

Whether it is 20 properties or 200, we scale our team to match the programme. Same quality, same point of contact, same reporting structure throughout. No drop-off as the programme grows.

Reporting and visibility

You know where every property is in the programme at any point. Which ones are surveyed, which are scheduled, which are complete and lodged. No chasing, no guesswork.

Everything under one contract.

One of the biggest headaches for housing associations is coordinating between different contractors for different measures. One company for the solar, another for the heating, another for insulation, and a fourth doing the electrical work. That is four sets of access arrangements, four invoicing streams, and four companies to chase when something needs attention.

We deliver every measure on the list. One procurement, one contract, one invoice per property. It is simpler for your team and a better experience for your tenants.

TrustMark Lodgement and EPC Updates

We work across the major funding programmes.

Whether your stock upgrade is funded through one of these programmes or self-funded, we deliver the same standard of work and compliance.

ECO4 and GBIS

Measures delivered against obligation targets with TrustMark lodgement. We work with the obligated parties directly and handle the compliance end to end.

SHDF and Warm Homes

Social Housing Decarbonisation Fund and Warm Homes Local Grant delivery. Multi-measure programmes with PAS 2035 compliance from assessment through to lodgement.

CHiL Framework

If your housing association works with any of the 15 Lancashire authorities on the CHiL framework, we are already an approved installer. Reference CHiL005.

Self-Funded Programmes

Not every stock upgrade needs to go through a government programme. We deliver the same standard of work, documentation and compliance on self-funded projects.
