What TrustMark does

TrustMark is the only UK Government-Endorsed Quality Scheme for home improvements, established in 2005 and headquartered in Basingstoke. It operates as a not-for-profit social enterprise under a Master Licence Agreement with the Department for Business & Trade, with oversight from the Department for Energy Security and Net Zero (DESNZ) on energy efficiency programmes. TrustMark functions as a three-tiered trust and certification platform: it licenses 40+ Scheme Providers (trade associations and certification bodies including FENSA, NAPIT, NICEIC, NFRC, MCS, and ECA), which in turn vet and manage 18,000+ Registered Businesses across 115 service types ranging from plumbing and electrical work to landscaping and retrofit installations. End consumers (UK homeowners) access these vetted tradespeople through the Find a Tradesperson directory, the Homeowner Portal, and the Home Improvement App developed with the Health and Safety Executive.

Direct peers

• Bark.com: UK-based services marketplace connecting consumers with local professionals across many categories including home improvement. Competes with TrustMark's directory for the same consumer demand-generation funnel.
• Checkatrade: UK's largest privately-run vetted-tradesperson directory. Directly comparable to TrustMark as a consumer-facing directory that vets and monitors tradespeople across the same home improvement categories, but without government endorsement.
• TrustATrader: UK directory that vets and rates tradespeople by region and trade. Closely comparable positioning to TrustMark as a vetting-led directory, though smaller in scale and without a government licence.
• Rated People: UK online marketplace that matches homeowners with tradespeople based on reviews and ratings. Directly competes with TrustMark's Find a Tradesperson directory for the same homeowner hiring flow.
• MyBuilder: UK tradesperson marketplace where homeowners post jobs and tradespeople quote. Overlaps TrustMark's core homeowner-to-tradesperson matching use case across the same trades.
• Local Heroes: British Gas-owned UK platform for booking vetted tradespeople for home repairs and improvements. A direct competitive overlap with TrustMark's homeowner-facing directory, though backed by a utility rather than government.
• Which? Trusted Traders: Consumer-organisation-backed directory of vetted UK tradespeople run by Which?. Closest direct peer to TrustMark in terms of vetting, endorsement-style positioning and consumer-trust brand, albeit backed by Which? rather than the UK Government.

Others

• NICEIC: UKAS-accredited electrical certification body and one of TrustMark's core Scheme Providers. Comparable as a trade accreditation body, but functions as a partner/distributor channel into TrustMark rather than a competing consumer brand.
