Understanding Home Improvement Badges: What Do They Mean for Your Home?

8th May 2025 - By Danelle Vanstone

When you’re hiring someone to work on your home, the logos and badges displayed on their van, website, or paperwork can feel reassuring — but how much do you know about what they represent?

This guide breaks down the most common trade badges in the UK so you can understand what’s essential, what’s good to have, and what matters when it comes to ensuring compliant, safe, and legal work in your home.

What Do These Badges Mean?

TrustMark (Government-Endorsed Quality)

• What it is: A government-endorsed quality scheme covering a wide range of trades in the home improvement sector.
• Who’s behind it: Endorsed by the Department for Energy Security & Net Zero (DESNZ), operated independently.
• What it means for you: Installers must meet strict standards for customer service, technical competence, and trading practices. They are subject to regular audits.
• Watch out for: TrustMark is an umbrella scheme — having the badge doesn’t automatically mean a trader is qualified for your specific project unless they hold relevant trade-specific membership. Also, notifiable work (like window replacements) still needs a separate Building Regulations Compliance Certificate (BRCC).

Federation of Master Builders (FMB)

• What it is: A trade association representing small to medium-sized building companies across the UK.
• Who’s behind it: An independent organisation that vets and inspects members.
• What it means for you: Members agree to a code of practice and meet certain quality standards. FMB also offers dispute resolution services.
• Watch out for: FMB membership focuses mostly on general building work — always check the installer’s specific experience for your type of project.

Which? Trusted Trader

• What it is: An endorsement scheme run by Which? that vets traders for compliance with a code of conduct and customer service standards.
• Who’s behind it: Which?, the well-known consumer rights organisation.
• What it means for you: Businesses undergo checks, interviews, and an assessment of their past work. Maintaining membership requires ongoing compliance.
• Watch out for: It’s a paid-for scheme — while useful, many excellent tradespeople may not be listed. Always verify trade-specific qualifications as well.

Checkatrade

• What it is: A lead generation platform and directory for tradespeople, featuring customer reviews.
• Who’s behind it: Privately owned marketing business.
• What it means for you: Traders agree to a code of conduct and provide insurance and ID checks. Past customer reviews offer insights into their work.
• Watch out for: Membership is paid. Once initial checks are passed, not all members are subject to ongoing vetting.

TrustATrader / MyBuilder / Bark

• What they are: Online platforms connecting homeowners with tradespeople who bid for work or advertise services.
• What it means for you: Access to reviews and comparison quotes. Some platforms offer basic vetting of tradespeople.
• Watch out for: Quality varies widely. While helpful for sourcing options, these platforms don’t verify compliance with Building Regulations — you must confirm/obtain certification yourself.

Google Reviews

• What it is: Public star ratings and reviews left by previous customers.
• Who’s behind it: Open to anyone with a Google account.
• What it means for you: Provides a snapshot of customer experiences and can indicate reputation.
• Watch out for: Reviews can be manipulated, fake, or lack context. Look for consistent patterns and combine feedback with official certification for the full picture.

Certass & Certified Competent

• What it is: Certass is a Government-licensed Competent Person Scheme (CPS). It certifies window and door installers to self-certify their work as compliant with Building Regulations. Certified Competent is backed by Certass and offers homeowners an online directory of competent tradespeople, customer reviews, galleries of past work, details of certifications, and helpful advice for choosing a reliable installer.
• Who’s behind it: Certass Ltd, audited annually by UKAS and licensed by the Government.
• What it means for you:
  • When you hire a Certass Certified Competent installer, your completed installation will be registered with local authority building control.
  • You’ll receive a Building Regulations Compliance Certificate (BRCC) — a legally recognised document required when selling your home (also referred to as a “FENSA certificate” but issued by Certass instead).
  • All Certass installers are subject to regular audits and are supported with technical updates and ongoing professional development (Mandatory Technical Competence – MTC).
• What is notifiable work?
  • Replacing windows and external doors within the thermal envelope of your home is notifiable, meaning it must legally be reported to building control.
• Watch out for:
  • Don’t be confused by brand names. Whether you receive a “FENSA certificate” or a Certass-issued BRCC, they are legally the same.
  • Make sure your installer provides the BRCC after the job is complete and keep it safe for future property transactions.

The Bottom Line:

Not all badges are created equal. Some offer customer reassurance. Some are simply directories or review platforms. Only Certass (and similar Competent Person Schemes) provide the legal paperwork you need for compliant, safe, and lawful improvements to your home.
