What is a TrustMark renewable energy installer?
A TrustMark renewable energy installer is a business shown in the live TrustMark directory with licensed trades relevant to work in and around the home. TrustMark describes itself as the UK’s Government Endorsed Quality Scheme and says it works through Scheme Providers that license registered businesses against standards of technical competence, trading practices and customer service.
For a homeowner, the useful point is that the listing has a defined scope. Therefore, it is sensible to check the live business record, legal company name and licensed trade before treating a logo on a quote or advertisement as current. A directory record is a valuable due-diligence step, but it does not decide whether a particular property, system design or proposal is right for you.
Start with the official TrustMark directory
The best starting point is the TrustMark Find a Tradesperson directory. Search for the business, then open its own record rather than relying on an image of a badge.
Take time to check the legal business name, published contact details, licence number, listed Scheme Provider and the licensed trades. It is also worth comparing the name on the proposal with the name in the directory. If the names differ, ask who will contract for, install and support the work before you proceed.
What should you check alongside the listing?
TrustMark says its registered businesses are required to meet standards of technical competence, customer service and trading practices. Its consumer guidance also says every registered business must have a clear, fair and transparent complaints process.
TrustMark states that registered businesses provide a minimum two-year guarantee for work carried out in and around the home. However, the documents for a renewable-energy project can still be different: there may be separate terms for equipment, workmanship, installation scope, servicing and any other cover. Read the documents for your own project carefully, including the provider, duration, exclusions and route for raising a concern.
In addition, ask for a clear written proposal. For solar, that should explain the intended panel layout, assumptions and scope. For a battery, it should make clear whether the proposal is for a new solar-and-battery system, a retrofit or a battery-only route. For heating, the right solution depends on a survey and the property’s existing system. A general TrustMark listing cannot make those design decisions for you.
TrustMark and MCS check different things
TrustMark and MCS are separate checks. TrustMark’s record shows a business’s licensed trades and Scheme Provider, while the MCS certified solar installer guide explains how to check the separate MCS technology record.
Where either directory matters to your decision, check both live records and make sure the legal entity and the relevant technology or trade line up with the proposed work. Do not treat a directory entry as an automatic grant decision, confirmation of warranty cover, product approval, performance promise or property-suitability assessment.
What HEG’s current TrustMark record shows
The official TrustMark business record was checked on 15 October 2026. It lists Home Energy Group Ltd, licence number 3900333, for Solar Panel Installers (PV), Battery Storage Systems and Air Source Heat Pump Installers. The record names The Installation Assurance Authority as the Scheme Provider.
These are directory-scope facts only. They do not guarantee that every property, product, design, installation date, funding route or customer outcome will be suitable. HEG confirms the appropriate route through the normal conversation, survey and written proposal process. You can check the current record directly in the official Home Energy Group Ltd TrustMark listing.
Use the record as part of a practical comparison
Start with the live directory record, then compare the written scope, property survey and support arrangements. For a solar starting point, HEG’s Solar Panels page and Solar Tool can help you explore the main questions before a survey-led quote. If you are considering storage or heating, the Battery Storage and Heat Pumps pages explain the different HEG journeys.
A written proposal and a property-specific survey remain the right place to confirm the final design, scope, responsibilities and price. Call HEG on 01535 210050 or request a survey-led quote to discuss the right next step for your home.
