FAQs about PAT Testing Frequency
How often do I need PAT testing done?
PAT testing needs to be done as often as a risk assessment recommends… that’s what the guidance says. You or another competent person should carry out an electrical / fire prevention risk assessment on all electrical appliance types and determine what maintenance is required and what risks could arise from the use of the appliance. We can do this for you too.
To make the process easier the Health and Safety Executive offer excellent guidance on retest periods based on environment types; for example equipment on a building site should be tested every 3 months; whilst stationery equipment in an office only needs a test every 4 years.
Best practice still recommends that you get tested every 12 months; especially if you are not planning to do anything in-house.
When you get your PAT testing done by us we will automatically assess your risks, and recommend appropriate intervals for you; saving you the hassle.
But how often is PAT testing required by law?
Sorry but there isn’t a straight answer for this one; we wish there was – it would make our job much easier! It comes down to a risk assessment every time.
How long does a PAT test last?
When you get the MOT done on your car, you can drive it away having successfully passed then on the way home your headlight goes off.. that would have been a failure a few minutes earlier. And if the Police spot you driving at night they may stop you and give you a ticket. You are now responsible for getting the fault fixed and should get the MOT done again, although few of us actually do as it is not a legal requirement.
It’s the same with PAT testing – you get the PAT done on your appliance, let’s say an electric drill; it passes and gets a pass label put on. You start using it again, and accidentally catch the cable with the drill bit and cut through it. It’s no longer safe and needs repairing; so you repair it. As an employer or self employed person, or even an employee you are responsible for health and safety, and are required to do a ‘user check‘ on an appliance before use. If the lead is damaged you should not use it and get it repaired by a competent person. Covering it in insulation tape is not acceptable.
After the repair it should get tested again, because in this case the lead will have had to be cut back and a new plug fitted, or the lead replaced fully, so the existing PAT test results are no longer valid; but not many people do this as it is not a legal requirement.
So, how long does a PAT test last? It is over as soon as it is over; it doesn’t have an expiry. It is only really valid at the time it is done, although we can assume if an appliance is tested, passes, then never moves or gets damaged in any way, the chances of a defect occurring are very low, so it should be ok to continue using until the recommended retest period. Its because of this supposed grey area that many get tested annually because that seems the obvious choice, although generally not the most appropriate.
How do we determine the risk?
The environment an appliance is used in is actually what is taken into account the most; most guidance tables you’ll find focus on the environment, because this is what people can most easily relate to. For example, an office is likely much safer than a building site – the office is low risk, whilst the building site is high risk.
In an office a computer on a desk never moves, so it is very low risk, so does it need testing every year? No. Maybe every 2-4 years. However power tools on a site get bashed around, they get wet and muddy, so they need testing a lot more often – every 3 months is the norm, with inspections every month and before each use by the user.
However, sometimes the user has to be consider too – a school is a fairly safe environment so you’d say the school is low risk; but children have a habit of breaking things, so the risk goes up, probably not up to high risk, but certainly medium – but is all equipment medium risk? No, because staff tend to look after their equipment better. So all the office equipment for example, could be low risk. This means in a school the office equipment may only need testing every 2-3 years, whilst the equipment in classrooms should be tested annually. But the risk is probably higher than annual so there is a reliance on the teachers to check and report any faults that arise in the mean time.
These are just examples, but are factors that need to be taken into account.
When should PAT testing be done and how often should you pat test?
PAT testing should be done initially and then it should be done as often as is necessary to maintain safe equipment. These are not questions easily answered in a short answer on a website, but can be easily answered after we have seen your site, and tested your equipment so the first thing to do is book us to do your initial testing.
How often should you get PAT testing done?
PAT testing should be completed as often as is necessary depending on the risks associated with the equipment use, and the environment it is being used in. We can assess this and guide you into what would be the most appropriate frequency for your business when we do your testing. When you do a risk assessment you must always consider your insurance policy as that may insist on annual testing, but as a general rule the following usually applies:
- Equipment that never moves in an office like a server or fixed appliance should be tested every 5 years
- Other office equipment such as computers should be tested every 2 years (at most)
- Equipment in a factory or workshop should be tested every year
- And tools used on a building site should be tested every 3 months
How often will our Server need testing?
Server systems are made up usually of IT equipment, and are stationery appliances, usually powered off a large surge protected socket extension, contained in a controlled ‘cage’ system. A server is usually monitored and maintained by a specialist engineer from an IT team; this should reduce the risk.
Being stationery IT equipment, that is managed a server shouldn’t need testing as often as say a computer in an office, so it is generally accepted that a full test every 5 years is sufficient; although this should be every 5 years from install, not from the start of a PAT testing programme.
If interim inspections are required, without unplugging the items there is little an engineer can do but look at what they can see; some companies will still label up each part, which isn’t totally wrong but some would question what they are actually doing. To enhance this, we have a thermal image camera; although not carried by all engineers we can arrange for this to be carried out to check for any overly hot spots in the system.
Our Equipment is used by the public, how often should it be tested?
Equipment used by the public should be tested on an annual basis to make sure it is maintained in good condition – you should also make sure you inspect it regularly because a year is a long time and issues can occur in-between tests.
