PAT Testing Qualifications and Training: What You Actually Need

For PAT testing, the key requirement is that the work is carried out by a competent person. Competence means having the knowledge and practical skill to choose the correct inspections and tests, carry them out safely, and interpret results properly. In other words, PAT testing doesn’t have to be done by a qualified electrician.

This page explains what “competent” means in practice, when a formal qualification (such as City & Guilds 2377) is useful, and which route makes sense depending on whether you’re managing PAT testing, doing it in-house, looking for a job, or planning to offer PAT testing commercially.

Quick guide: which route applies to you?

• I’m responsible for safety as a manager / duty holder: see Managing PAT testing in the workplace.
• I want to do PAT testing in-house: see Can I do my own PAT testing?.
• I want a job as a PAT tester: see How to become a PAT tester and our PAT testing job vacancies.
• I’m starting a PAT testing business: see Starting a PAT testing business.
• I’m a landlord supplying appliances: see PAT testing for landlords.
• I’m a charity shop / selling donated goods: see PAT testing in charity shops.

What does 'competent person' mean?

A competent person should be able to:

• understand what falls within scope (and what doesn’t) – see what PAT testing covers
• carry out a proper formal visual inspection (where most faults are found)
• select appropriate tests for the equipment type and construction (Class I, Class II, Class II FE, etc.)
• interpret results, including knowing when readings can be misleading
• record results properly (including measured values, not just pass/fail) – see PAT testing records and labels

In short: PAT testing is really in-service inspection and testing of electrical equipment. The inspection is fundamental, and testing only adds value when the correct tests are applied and interpreted correctly.

Do you need a qualification?

There is no legal requirement to hold a specific PAT qualification. However, qualifications can be useful because they provide evidence of training and competence, and many employers or clients expect them.

As a general rule:

• In-house testing (schools, offices, facilities teams, landlords, charities): a practical one-day competence-focused course is often the most suitable route, provided you only test within your organisation and you understand your limitations. See doing PAT testing in-house.
• Commercial PAT testing / career route: employers often look for City & Guilds 2377 (or equivalent), particularly for full-time PAT roles and contractor work. See how to become a PAT tester.

City & Guilds 2377: when does it matter?

City & Guilds 2377-77 is the current widely-recognised qualification for in-service inspection and testing of electrical equipment. It is often requested by employers, larger clients, and some insurance schemes for businesses offering PAT testing as a service.

Doing PAT testing in-house: why it works well

For many organisations, in-house PAT testing is the simplest way to stay in control: you can test equipment when it suits you, reduce disruption, avoid missed items, and set sensible frequencies based on your own environment and equipment. The key is making sure the person doing the work is trained, uses the right equipment, and follows a consistent record and defect process.

Starting a PAT testing business: competence still comes first

PAT testing has relatively low barriers to entry, which is both the opportunity and the risk. If you’re offering PAT testing as a service, you need a professional approach to competence, records, equipment selection, calibration, insurance, and customer expectations.

Landlords and charity shops: extra care with supplied equipment

If you supply electrical appliances as part of a tenancy or resale (including charity shops), you’re taking on additional responsibility for safety. Inspection and testing is widely used as a practical way to demonstrate due diligence, but it needs to be done properly, with clear records and an effective fail/removal process.

Training and next steps

If you want to carry out PAT testing competently (whether in-house or professionally), hands-on training is the quickest way to build confidence with inspection technique, test selection, limits, and record keeping. Our PAT testing courses cover the practical skills needed to carry out inspection and testing safely and correctly.
