Searching the registers? Look for CT Eco Ltd

We changed our company name to Alpha Energy Group Ltd on 4 July 2026. It is the same company, the same registration numbers and the same team — company number 12528640 either way. The schemes below are updating their records, so until they do, our entries still appear under our former name, CT Eco Ltd.

Why this page exists

Anyone can put a logo on a website. Every scheme below runs a public register, so you can check us independently rather than taking our word for it — and we would rather you did.

What we install, and what we don’t

Certification is specific to the measure, not the company, so it is worth being clear about the boundary. Our MCS certification covers solar PV and air source heat pumps. Our TrustMark licence additionally covers loft insulation, internal wall insulation, cavity wall internal insulation, gas fired condensing boilers, electric storage heaters, and heating and hot water controls. Battery storage sits under our RECC membership. We install all of these ourselves.

We do not offer external wall insulation. If that is what your property needs, we will say so and point you towards installers who are certified for it, rather than take on work outside our scope.

If any part of a job ever is subcontracted, we remain your point of contact, the work stays covered by our TrustMark registration and our complaints procedure, and we will tell you in advance.
