Why Choosing a TrustMark Installer Matters for Your Home Improvements

When it comes to home improvements—whether it’s installing a new boiler, insulating your loft, or making your home more energy efficient—trust is everything. With so many tradespeople and companies offering services across the UK, it can be difficult to know who to rely on. That’s where TrustMark installers, like Fairway Energy, come into play.
If you’re unfamiliar with the term, TrustMark is a government-endorsed quality scheme that aims to help consumers find reputable and trustworthy tradespeople. In this article, we’ll explore what TrustMark is, why using a TrustMark-registered installer matters, and how to make sure your chosen contractor is properly accredited.
What is TrustMark?
TrustMark is the only government-endorsed scheme in the UK covering work a consumer chooses to have carried out in or around their home. It covers everything from plumbing and heating to energy efficiency upgrades and general building services. The scheme’s primary goal is to provide assurance that registered tradespeople are competent, qualified, and working to a high standard.
To become a TrustMark-registered installer, a tradesperson or business must go through a thorough vetting and onboarding process. This includes checks on their technical competence, trading practices, and customer service. They must also commit to continuous improvement, follow the TrustMark Code of Conduct, and agree to be inspected by the relevant scheme providers.

Why Use a TrustMark Installer?
- Peace of Mind
When you choose a TrustMark installer, you’re getting more than just a tradesperson—you’re getting the peace of mind that comes with government-backed quality assurance. You’ll know that the work will be done to a recognised standard and that any issues can be addressed through proper channels. - Consumer Protection
TrustMark provides added consumer protections that standard tradespeople may not offer. This includes dispute resolution services, access to complaints procedures, and even insurance-backed warranties in some cases. This is especially important for larger projects like insulation, heating systems, or renewable energy installations. - High Standards of Workmanship
All TrustMark installers are subject to regular quality checks and audits. This means they must consistently deliver high-quality work in line with both industry and TrustMark standards. The accreditation is not a one-time badge—it’s something that must be maintained. - Eligibility for Government Schemes
If you’re looking to take advantage of schemes like the ECO4 grant, the Great British Insulation Scheme, or other energy efficiency funding, you’ll usually need to use a TrustMark-registered installer. These schemes are designed to improve the UK’s housing stock, reduce emissions, and lower energy bills—but they also come with strict guidelines, one of which is ensuring the work is carried out by accredited professionals.
What to Expect from a TrustMark Installer
A reputable TrustMark installer should demonstrate professionalism from the very beginning. Here’s what you can typically expect:
- Transparency: You should receive clear and detailed scope of work, materials used, timelines, and any potential extras.
- Documentation and Guarantees: Expect to receive all necessary paperwork, including contracts, guarantees, warranties, and any relevant compliance certificates.
- Polite, Respectful Conduct: Good customer service is a key part of the TrustMark standard. Installers should communicate clearly, arrive on time, and respect your property.
- Aftercare and Support: Should anything go wrong after installation, a TrustMark installer will be expected to respond promptly and professionally, ensuring you’re not left stranded.
How to Find a TrustMark Installer
Finding a TrustMark-registered installer is straightforward. Simply visit the official TrustMark website to verify an installer’s credentials.
Before hiring an installer, be sure to:
- Check Reviews and References: While TrustMark provides a baseline of trust, it’s still wise to check independent reviews or ask for references.
- Verify Credentials: Some trades require additional qualifications or registrations (e.g., Gas Safe for gas work or MCS for renewables). Ensure your installer is appropriately accredited.
- Ask Questions: Don’t be afraid to ask how long the installer has been in business, what similar projects they’ve completed, and what kind of guarantees they offer.
Common Trades Covered by TrustMark
Here are just a few of the services that TrustMark-registered professionals typically offer:
- Home insulation (loft, cavity wall, solid wall)
- Central Heating
- Ventilation
- Renewable energy solutions (solar panels, heat pumps)
- and other home improvement work
Whether you’re upgrading for comfort, value, or energy efficiency, choosing a TrustMark-accredited installer is a wise choice.
TrustMark and the ECO4 Grant Scheme
The ECO4 (Energy Company Obligation) scheme provides funding to help UK households improve their energy efficiency. This includes improvements such as insulation, boiler replacements, and solar PV installations. Crucially, only work completed by TrustMark-registered businesses qualifies for the grant.
This requirement ensures that public money is spent wisely, and that installations meet strict quality, safety, and efficiency standards. If you’re thinking about applying for ECO4 funding, make sure any company you engage is both TrustMark certified and holds other relevant accreditations for renewables or gas.
Final Thoughts
In a world where rogue traders and fly-by-night companies still pose risks to homeowners, TrustMark offers a layer of protection and reliability. By choosing a TrustMark-registered installer, you’re not only safeguarding your home and finances—you’re also helping to raise the standard of work across the UK’s home improvement sector.
Whether you’re opting for energy efficiency, safety upgrades, or general improvements, working with a TrustMark installer ensures your project is in safe hands from start to finish.
