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
- Enhanced DBS checks for work in schools, care homes, and sensitive premises
- 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
