METS - Specialists in PAT Testing

Portable appliance testing is vital to protect your business and its employees. We aim to give the best service in Ireland to enable our customers to fulfill their obligations with regard to equipment safety.

Electrical safety obligations are not limited to businesses, of course; landlords are also responsible for ensuring the regular testing of all appliances they provide for their tenants. All portable appliances with mains plug need testing. This includes:

Thermal Imaging Services Bullet Point  Computers, monitors and peripherals requiring mains power
Thermal Imaging Services Bullet Point  Audio and telephone equipment requiring mains power
Thermal Imaging Services Bullet Point  Kettles, microwave ovens and other kitchen appliances
Thermal Imaging Services Bullet Point  Vacuum cleaners

We use the latest PAT equipment to test both 230V and 110V appliances and, as specialists in PAT testing, we are best placed to help you comply with your legal obligations. All our testing is carried out in accordance with The Institute of Electrical Engineers ' (IEE) code of practice.

Make sure your appliances are safe! Make sure they are TESTED!
Why PAT Test?

PAT testing service
The applicable legislation namely Part 3 Section 81(Electricity) of the Safety Health and Welfare at Work General Application Regulations 2007 states that the Employer shall ensure that portable electrical equipment is periodically inspected and tested by a competent person. The legislation also states that the equipment should be certified as to whether it was safe and without risk to persons coming into contact with the equipment.

PAT testing is generally regarded as being the best way of meeting the electrical regulations that exist to protect employees, customers and tenants. Without it you could be in a very difficult situation if an electrical accident were to occur.

All portable electrical equipment is subject to getting damaged during use, and this damage could render the equipment dangerous to the user. Without a regular programme of testing and inspection, you have not taken reasonable steps to ensure the safety of users.

Tests and inspections should be made at reasonable and regular intervals, bearing in mind the rate of use of both portable and fixed appliances.

Failure to comply with the Electrical Regulations may constitute a criminal offence under the Consumer Protection Act 1987 which carries a maximum penalty on summary conviction Landlords and letting agents could also be sued in Civil Law under the duty of care for failure to ensure the tenants safety and as a result, face punitive damages.

PAT Testing for Bussiness


As a business, you have a duty to prevent any harm coming to your employees and customers. Portable appliance testing is one of the ways that you can comply with this obligation. Failure to implement a programme of regular appliance testing can also have insurance implications.

Insurance companies assume that when giving insurance cover to a business, the owners of that business are complying with all regulations necessary. An insurance company may reduce, delay or even refuse to pay on a claim for damage if an appliance that has not been tested has caused the damage.

The responsibility of employers

Electricity at work regulations 1989
Regulation 4 (2): 'As may be necessary to prevent danger all systems shall be maintained so as to prevent so far as is reasonably practicable such danger.'

To meet the requirements of the 1989 Electricity at work regulations, it is widely regarded to be necessary to implement a programme of planned inspection and testing of portable appliances.

In the Health & Safety at Work Act 1974, all employers have a legal duty to provide safe plant and equipment and every employer must ensure that equipment must be maintained in an efficient state, in efficient working order and good repair.


PAT Testing for Landlords

As a landlord, you have a duty to prevent harm to your tenants from electrical appliances that you supply. Portable appliance testing is widely regarded as being the best way of complying with this obligation. Without a programme of planned appliance testing and maintenance, you could be legally liable for damages resulting from your untested appliances. This covers all portable appliances that you supply, including fridges and freezers, microwave ovens, televisions and vacuum cleaners.

The regulations on electrical appliances for landlords and/or letting agents

The Electrical Equipment (Safety) Regulations 1994, mandatory since 1 January 1997 , state that all electrical appliances supplied with let accommodation must be safe. This applies to both new and second-hand appliances and covers all electrical items supplied for the intended use of the Tenant. The only sure method of ensuring that these appliances are safe is to have them tested by a trained competent person using the appropriate calibrated portable appliance testing equipment.



The PAT Testing Process




Portable appliance testing includes a thorough visual check of the appliance and a series of tests on professional PAT testing equipment.

The appliance or lead being tested is checked for a variety of faults, and given a pass or fail sticker as appropriate. A certificate of testing is also provided for the business showing the results of all tests. We will effect minor repairs at the time of testing (for example an incorrect fuse rating or damaged plug or IEC lead) in order that the equipment is safe to use and can be passed; more significant faults or damage will be reported to the manager.

The testing will involve switching items off if they are already on. To minimize disruption to staff and customers, the testing can be done out of hours in most circumstances - contact us for details.

All testing is carried out in accordance with The Institute of Electrical Engineers ' (IEE) code of practice, with full public liability insurance.

Test Procedure is as follows



Visual inspections should be carried out by persons competent to do so. The following must be considered when carrying out the inspection.

  • Thermal Imaging Services Bullet Point  The flexible cable
  • Thermal Imaging Services Bullet Point  The socket outlet, if known
  • Thermal Imaging Services Bullet Point  The appliance
  • Thermal Imaging Services Bullet Point  The plug head
  • Thermal Imaging Services Bullet Point  Some non rewire able plugs cannot be opened for inspection.
  • Thermal Imaging Services Bullet Point  Signs of overheating burnt odors, stressed cables.
  • Thermal Imaging Services Bullet Point  Security of all terminal screws.
  • Thermal Imaging Services Bullet Point  Correct fuse - BS, ASTA marked.



We use the Robin 5500 instrument for conducting our tests. The units are independently calibrated and certified.

1Earth Bond

The first required test is the Earth Bond test. This verifies the integrity of the earth on the appliance. Our testers can also check IT equipment through an approved test that uses a reduced test current which will not damage electronic equipment.

2Insulation Test

The next required test is the Insulation test. This verifies that the insulation on cables and tracks in the appliance is sufficient to isolate the live conductors from the earthed parts of the appliance.

3Earth Leakage Test

This is a further test of the insulation under operating conditions. This can be useful for finding if an appliance is causing nuisance tripping of RCD's.


4Run Test

This can be used to ensure that the appliance is not drawing excess current at startup.

5Flash Test

This is an insulation test carried out at more vigorous test voltages and should be used with caution.

6Polarity Test

This is used to verify the polarity of leads etc.
