How to Choose a PAT Testing Company

Not all PAT testing providers are equal. Here's what to look for — and what red flags to avoid — when selecting a PAT testing company for your business.

With many providers offering PAT testing services, choosing the right one can be confusing. The lowest price isn't always the best option — a poorly conducted PAT test provides no real safety benefit and may not satisfy your insurance or regulatory requirements. Here's what to look for.

Essential Qualifications to Check

  • NICEIC approval — confirms the company meets rigorous technical and business standards
  • City & Guilds 2377 qualification for individual engineers
  • CSCS cards for engineers working on construction sites
  • Full public liability insurance (minimum £1 million, ideally £5 million+)
  • Professional indemnity insurance

What to Look for in the Service

  • Certificates and appliance labels included in the price (not charged separately)
  • Digital certificates provided same day
  • Secure online storage of historical records
  • Clear, itemised test reports listing every appliance with results
  • Out-of-hours and weekend availability
  • Annual renewal reminders

Red Flags to Avoid

  • Prices that seem too low to include a qualified engineer and proper certification
  • Certificates that don't include engineer qualifications or certification body details
  • No willingness to provide references or evidence of qualifications
  • No public liability insurance
  • Inability to provide emergency lighting or fixed wire testing if needed
