Planning a loft conversion in London? Trust and quality are essential. That’s why LMB Group is proud to be accredited by TrustMark, the only government-endorsed quality standards scheme for trades operating in and around the home.
This accreditation isn’t just a badge—it’s a promise. It means that when you work with LMB Group, you’re choosing a company that meets strict standards for workmanship, customer care, and reliability. In this article, we’ll explain what TrustMark is, why it matters, and how it benefits you as a homeowner.
What is TrustMark?
TrustMark is the UK’s only government-endorsed quality scheme for tradespeople. It was created to give homeowners peace of mind when hiring companies for work in and around the home. Whether you’re looking for a loft conversion, insulation, solar panel installation, or double glazing, TrustMark ensures that the company you choose operates to the highest standards.
Every TrustMark member must follow a Code of Conduct and Customer Charter, which guarantees fairness, transparency, and professionalism. This means you can expect:
- Competence: Your chosen company has the skills and knowledge to deliver exceptional results.
- Quality Assurance: Work is regularly inspected to maintain high standards.
- Customer Care: You’ll be treated fairly, and your interests will always come first.

Why TrustMark Matters for Homeowners
Home improvement projects can be stressful. From choosing the right design to managing budgets, there’s a lot to think about. TrustMark takes away some of that stress by giving you confidence in the company you hire. Here’s why it’s so important:
- Peace of Mind
TrustMark accreditation means your contractor has been vetted and approved. You’re not just relying on word-of-mouth or online reviews—you have government-backed assurance that the company meets strict standards. - Financial Protection
For government-funded projects like ECO (Energy Company Obligation), TrustMark membership is mandatory. This ensures that if a company ceases trading during the guarantee period, you’re still protected. - Fair Treatment
The Customer Charter ensures that you’ll be treated fairly throughout the process. From the initial quote to the final handover, your rights as a consumer are safeguarded. - Regular Inspections
TrustMark members are subject to ongoing checks and inspections. This means standards aren’t just met once—they’re maintained over time.

How to Spot a TrustMark Company
When choosing a contractor, look for the TrustMark logo. It’s a symbol of reliability and quality. You can also check the official TrustMark website to verify membership. If a company claims to be accredited but isn’t listed, that’s a red flag.
