TrustMark Accreditation

Why it pays to be part of TrustMark – the BBA backing quality in construction

TrustMark is a not-for-profit organisation, licensed by Government and supported by trade associations within the construction industry and consumer protection groups. It exists to help consumers find reliable and trustworthy tradespeople to carry out repairs and improvement to their homes.

TrustMark approves trade associations and industry groups who can demonstrate that they meet a strict code of practice. Using a TrustMark-registered tradesperson provides assurance to the householder that any installation work will be carried out efficiently and to a high standard.

The BBA acts as a Scheme Operator for, and provides inspection services to other scheme operators such as:


  • BBA Approved Installers under Cavity Wall Insulation and Loft Insulation
  • Diversity
  • Federation of Master Builders (FMB)
  • Fairtrades
  • The Consumer Protection Association
  • Velux Approved Installer Scheme

TrustMark-registered firms are expected to be of the highest standard and to operate to Government-endorsed standards. Every firm’s technical skills are independently checked through on-site inspections, as well as background checks on its trading records and financial status.

Qualified BBA inspectors undertake these visits, meaning that technical competence, as well as proper business practices and customer satisfaction are properly monitored. All our field Inspectors have an extensive background in the Insulation industry. Their professionalism is the foundation of what the BBA stands for with each having all the knowledge and skill to provide the high standards required in the Energy Efficiency industry.

TrustMark is a scheme that checks all three cornerstones of quality: trading practices, customer care and technical competence. Firms that fail to meet TrustMark standards can be taken through a complaints and disciplinary process, and Scheme Operators offer an effective dispute resolution service to firms and their customers.
