PAT Testing Costs: What You'll Actually Pay in 2026

PAT testing costs between £1 and £3 per appliance for outsourced testing in most of the UK. For a typical office with 80 appliances, that's £120–£240 every testing cycle. It's one of the cheapest compliance obligations most businesses will deal with — but pricing varies enough that it's worth understanding what drives it.

Here's a full breakdown of what you'll pay, whether you outsource or do it yourself, and where the real costs hide.

Outsourced PAT testing costs

Most UK businesses outsource PAT testing to a contractor who visits the premises, tests everything, and provides records. Pricing is almost always per-appliance, with discounts for volume.

Typical per-appliance pricing

Number of appliances	Cost per appliance
1–50	£2.00–£3.00
50–200	£1.50–£2.00
200–500	£1.00–£1.50
500+	£0.80–£1.20

These are approximate ranges based on the UK market. Prices vary by region. London and the South East tend to be at the top end; the Midlands and North are typically lower.

Minimum call-out fees

Most contractors charge a minimum call-out fee of £50–£80, regardless of how many appliances you have. If you've only got 10 items, you'll pay the minimum — not 10 × £2.50. This is the main reason very small businesses pay more per appliance than larger ones.

Some contractors absorb the call-out fee once the job reaches a certain size (often around 30–40 appliances). Ask before booking.

What's included in the price

A standard outsourced PAT testing visit typically includes:

Combined inspection and testing — visual inspection plus electrical tests (earth continuity, insulation resistance) using a calibrated PAT tester
Pass/fail labels — applied to each appliance after testing. For more on what these labels mean, see our guide to PAT testing labels
A test record or certificate — either a paper register, a spreadsheet, or a digital report. The format and quality varies significantly between contractors
Failed item identification — appliances that fail are labelled and noted in the report. Repair or disposal is usually your responsibility

What's not usually included: replacement fuses, replacement plugs, rewiring of faulty leads, or disposal of failed equipment. These are extras, and contractors charge for them separately.

Certificates vs register entries

Some contractors offer "PAT testing certificates" as an upsell, sometimes charging £10–£25 per certificate on top of the per-appliance fee. The IET Code of Practice doesn't require individual certificates for each appliance — a properly maintained register with the correct fields is sufficient for compliance. Don't pay extra for certificates unless your insurer or a specific regulation applicable to your sector explicitly demands them.

What you do need is a complete PAT testing record with appliance ID, test date, results, tester name, and next test date. Any contractor worth hiring will provide this as standard.

In-house PAT testing costs

For organisations with a larger number of appliances, bringing PAT testing in-house can be significantly cheaper over time. Here's what you'll spend.

PAT tester purchase

Category	Price range	Suitable for
Entry-level	£200–£350	Basic pass/fail testing, small inventories. Manual recording of results. Limited test functions.
Mid-range	£400–£700	Most in-house testing needs. Typically includes earth continuity, insulation resistance, lead polarity, and earth leakage tests. Many models offer digital storage or Bluetooth download of results.
Professional	£800+	High-volume testing, advanced diagnostics, built-in barcode scanning, direct database upload. Aimed at professional PAT testing contractors.

For a typical office or small multi-site organisation, a mid-range tester in the £400–£600 bracket covers everything you need. Entry-level units work fine for the electrical tests themselves, but the time you'll spend manually recording results adds up quickly.

Training

The person carrying out PAT testing must be competent. The Electricity at Work Regulations 1989 require it, though they don't prescribe a specific qualification.

A one-day PAT testing training course costs £150–£300. These courses cover the IET Code of Practice requirements, how to use a PAT tester, how to interpret results, and how to maintain records. City & Guilds 2377 is the most widely recognised PAT testing qualification, though it's not legally required.

Some PAT tester manufacturers offer free or discounted training when you buy their equipment. Check before purchasing separately.

Ongoing costs

Once you own the equipment and have a trained tester, the per-appliance cost drops dramatically. But there are recurring expenses:

Labels and stickers — Pass/fail labels, typically £10–£20 per roll of 500. Budget around £0.02–£0.04 per appliance per test cycle.
Calibration — PAT testers should be calibrated annually. Cost: £30–£60 per year, depending on the manufacturer and service provider.
Replacement leads and accessories — Test leads wear out. Budget £20–£50 per year for replacements.
Time — The biggest ongoing cost. An experienced tester can complete a combined inspection and test in 3–5 minutes per appliance for straightforward items (kettles, monitors, desk lamps). More complex items, or items in difficult-to-reach locations, take longer. Factor in travel time between locations if you're multi-site.

Break-even analysis: in-house vs outsourced

The maths are straightforward. Take a mid-range scenario:

In-house setup costs:

PAT tester: £500
Training course: £200
First batch of labels: £20
Total year-one cost: £720

Outsourced cost for 150 appliances at £1.75 each:

£262.50 per testing cycle

At that rate, in-house testing breaks even after roughly three testing cycles. If you test on the IET Code of Practice's recommended schedule — which for office equipment means combined inspection and testing every 48 months — that's a 12-year payback period. Not compelling.

But change the numbers and it shifts fast:

250 appliances at £1.50 each outsourced = £375 per cycle. In-house breaks even in two cycles.
500 appliances at £1.20 each outsourced = £600 per cycle. In-house breaks even after the first cycle.
If you test more frequently — for example, industrial equipment on 12-month cycles — the break-even comes much sooner.

General rule: In-house testing starts making financial sense at around 100 appliances, and becomes the clear winner above 200. Below 100, outsourcing is usually cheaper and simpler.

The non-financial advantages of in-house testing are worth considering too: you control the schedule, you can test new equipment as it arrives rather than waiting for the next contractor visit, and you build internal competence in electrical safety.

What affects the price

Several factors push costs up or down, regardless of whether you outsource or test in-house.

Number of appliances

Volume is the single biggest factor. Every outsourced PAT testing provider offers lower per-item rates for larger batches. For in-house testing, the fixed costs (tester, training) get spread across more items, driving the per-appliance cost down.

Type of testing required

Not every appliance needs the same level of testing every time. The IET Code of Practice defines three levels:

User checks — free, done by staff, no formal recording needed
Formal visual inspection — no test equipment required, takes 1–2 minutes per item
Combined inspection and testing — requires a PAT tester, takes 3–5 minutes per item

If a contractor quotes you for combined inspection and testing on every appliance every year, question whether that level of testing is actually needed. Many office appliances only need a formal visual inspection annually, with a combined test every 48 months. Over-testing inflates costs without improving safety. See our PAT testing frequency guide for the recommended intervals by appliance type.

Location and travel

Contractors factor travel into their pricing. A business in a major city with easy access will pay less than a rural site an hour from the nearest tester. Multi-site organisations can sometimes negotiate better rates by booking all sites in one contract, allowing the contractor to plan an efficient route.

Access

If the contractor can walk through your premises and test everything in a single visit, the job is efficient. If appliances are locked in offices, mounted in ceiling voids, or scattered across a campus with restricted access, the job takes longer and costs more.

Prepare for the visit. Ensure all areas are accessible, appliances are plugged in and available, and someone is on-hand to unlock rooms. Wasted time on site costs you money.

Record format

Basic testing with a handwritten register is cheaper (from a contractor's perspective) than testing with digital records, barcode scanning, and formatted PDF reports. Most reputable contractors now include digital records as standard, but check what you're getting. A contractor who hands you a clipboard sheet with illegible handwriting is offering a false economy — you'll spend time transcribing records afterwards, or worse, you'll have records that won't stand up to an audit.

Hidden costs of not testing

PAT testing looks like a cost. Not PAT testing looks like a saving — until something goes wrong.

Insurance implications

Most employers' liability insurance policies include conditions around electrical equipment maintenance. If an incident occurs and you can't produce PAT testing records, your insurer has grounds to refuse the claim or increase your premiums. A single refused claim will cost orders of magnitude more than a decade of PAT testing.

Check your policy wording. If it references "maintenance of electrical equipment" or "portable appliance testing," assume that proper records are expected. For more on the legal framework, see our guide on whether PAT testing is legally required.

HSE enforcement

The HSE doesn't proactively audit businesses for PAT testing compliance. But after an electrical incident causing injury, they will investigate. They will ask for maintenance records. If you have none, that's evidence of a breach of Regulation 4(2) of the Electricity at Work Regulations 1989. The penalty for breaching these regulations is an unlimited fine or up to two years' imprisonment.

Civil liability

An employee or member of the public injured by a faulty portable appliance can bring a personal injury claim. Your ability to defend that claim depends on demonstrating that you took reasonable steps to maintain the equipment. A current PAT testing register is the most straightforward evidence of that. Not having one makes your legal position significantly weaker.

Reputational damage

For public-facing businesses — hotels, restaurants, retail — an electrical incident affecting a customer can cause lasting reputational harm. The cost of PAT testing a hotel's portable appliances is a rounding error compared to the cost of negative press coverage or a TripAdvisor review describing an electric shock.

Reducing costs without cutting corners

There are legitimate ways to spend less on PAT testing without compromising safety or compliance.

Group appliances for batch testing

If you outsource, consolidate your testing into a single visit per site rather than calling contractors out multiple times per year. The minimum call-out fee applies each time. One visit to test 100 appliances is cheaper than two visits to test 50.

For multi-site organisations, negotiate a contract covering all sites with a planned schedule. This gives the contractor predictable work, and you get lower rates.

Use formal visual inspections between full tests

The IET Code of Practice doesn't require combined inspection and testing at every cycle. For many office appliances, a formal visual inspection is recommended every 24 months, with a combined inspection and test every 48 months. If you're paying a contractor to do a full combined test on every appliance every year, you're almost certainly over-testing.

Train someone in-house to carry out formal visual inspections. No PAT tester is needed — just competence and a checklist. Use contractors for the combined inspection and testing cycles only. This can halve your outsourced testing costs for office environments.

For the recommended intervals by equipment type, see our PAT testing frequency guide.

Keep your register current

A well-maintained PAT testing register makes every test cycle faster. If the tester (whether in-house or a contractor) arrives and your register accurately lists every appliance with its location and unique ID, they can work through the list systematically. If the register is out of date, they'll spend time hunting for appliances, querying unlisted items, and reconciling discrepancies. That wasted time costs money.

Remove disposed appliances from the active register (but keep their historical records). Update locations when equipment moves. Add new appliances as they arrive, don't wait for the next test cycle. Use our PAT register template generator if you need a structured starting point.

Right-size your testing schedule

Use the PAT testing frequency calculator to check whether your current testing intervals match the IET Code of Practice recommendations for your equipment types and environment. Many businesses test more frequently than necessary because "annual PAT testing" has become received wisdom — despite the IET Code of Practice recommending 48-month combined test intervals for most office equipment.

Testing less frequently where the evidence supports it is not cutting corners. It's following the guidance correctly.

Consider a hybrid approach

For organisations in the 50–150 appliance range, a hybrid approach often offers the best value: purchase an entry-level PAT tester and train a staff member to carry out formal visual inspections in-house, then bring in a contractor for the combined inspection and testing cycles. You get the cost savings of in-house visual inspections with the assurance of professional electrical testing.

The bottom line

PAT testing is cheap. For a typical UK office with 80 portable appliances, outsourced testing costs less than £200 per cycle — and with the IET Code of Practice's recommended intervals, that cycle might only come around every four years for most items.

Compare that to the cost of an uninsured claim, an HSE prosecution, or a civil liability judgment. The numbers aren't close.

The real cost of PAT testing isn't the testing itself. It's the time spent managing records, chasing overdue retests, and preparing for audits. That's the problem PATvault solves — an online appliance register with automatic retest scheduling, audit-ready exports, and a clean interface built for facilities managers doing in-house testing.
