Install heat pumps under our MCS certification.
The MCS Master Partner Plan lets you offer MCS-accredited heat pump installations without holding your own certification — we handle design, compliance and certification while you focus on the installation.
Why join the MCS Master Partner Plan?
Offer fully certified installations — with the design, paperwork and grant admin handled by our team.
BUS grants for your customers
Eligible customers can access Boiler Upgrade Scheme support through our MCS certification. We handle the application process and check which grant applies.
No paperwork burden
We manage MCS documentation, building-regulations notifications, DNO applications and certification. You focus on the installation.
Expert system design
Our engineers provide complete system designs with MIS 3005-D-compliant heat-loss calculations, equipment specifications and schematics.
Technical support
Guidance from our experienced technical team throughout the installation, with phone support and site visits available when needed.
Equipment at trade prices
Heat pumps, cylinders and components supplied at trade prices through your Thermal Earth account.
Room to grow
Enter the heat pump market without the cost and complexity of maintaining MCS certification — build experience and grow at your own pace.

We provide an initial estimate from property details, then visit the site with you to complete heat-loss calculations and produce a detailed quotation.
Ordering & documentation
The customer signs with Thermal Earth — essential for MCS compliance. We handle sub-contractor agreements, deposits and equipment for delivery.
Pre-install meeting & install
Our project team meets you on site to review technical requirements. You complete the installation to our design, with technical support throughout.
