Are you planning a home retrofit? Whether you are upgrading insulation, adding solar panels or replacing your home’s heating system, choosing the right contractors is essential to ensure a smooth process. That’s where TrustMark and their licensed Scheme Providers come in. 

In this blog, we introduce TrustMark and how it helps to protect homeowners and landlords throughout the retrofit process. We’ll explain why it matters and how Digital Buildings, a TrustMark licenced Scheme Provider, is your ideal partner for your home improvement project.

 

What is TrustMark?

TrustMark is the only UK Government Endorsed Quality Scheme for work carried out in and round your home. When you choose a TrustMark Registered business, you are engaging in a business that has been thoroughly vetted to meet required standards and has made a commitment to good customer service.

The TrustMark quality schemes are mainly designed for:

  • Contractors and installers who want to demonstrate competence 
  • Surveyors and assessors working to official standards
  • Trade and certification bodies in the construction industry
  • Service providers like Digital Buildings 

In addition to meeting its TrustMark obligations Digital Buildings oversees the entire retrofit process at every stage through its Retrogreen service, which enforces guarantees and best practices throughout the customer journey.

 

Why TrustMark Matters for Retrofit Projects

This scheme plays a crucial role in the world of home retrofitting and energy efficiency upgrades. It helps to ensure that the work done on your property is compliant and completed to a high standard. Leaving your retrofit to cowboy contractors can cause costly mistakes. For example, poorly installed insulation can cause damp and mould.

That’s why TrustMark is important, as it ensures:

  • Only competent, vetted professionals carry out work on your home
  • Where required home improvements comply with PAS 2035, the British Standard and framework for achieving quality in energy retrofits of existing homes. 
  • Businesses adhere to high standards of workmanship, technical ability and customer service

 

Benefits for Homeowners and Landlords

Consumer protection

You’re covered by a formal complaints process and financial protection mechanisms.

Quality assurance

You know the work will be undertaken in accordance with official standards.

Increased property value

Quality-assured energy upgrades done correctly can enhance your home’s value or rental appeal.
