Fixed Appliance Testing Explained for Northern Ireland Businesses

Understand how hard wired equipment should be assessed and where fixed appliance testing sits alongside PAT testing and an EICR.

Some Equipment Sits Outside Ordinary PAT Testing

Fixed appliances are connected directly to the electrical installation rather than through an ordinary plug and socket. Common examples include hand dryers, water heaters and some commercial kitchen equipment.

Because the connection and construction differ from portable equipment, the inspection and testing method must suit the appliance. The scope should be agreed by someone who understands the equipment, how it is used and the environment in which it operates.

The connection method, equipment type and operating environment help determine the suitable assessment.

Equipment to Consider

Common Types of Fixed Appliance

These examples help organisations recognise equipment that may not appear on a portable appliance register. The exact testing requirement still depends on competent assessment.

Hand Dryers

Washroom hand dryers are commonly connected through a fused connection unit and should be identified within the equipment review.

Water Heaters

Local water heating equipment may be wired directly into the installation and exposed to regular use or moisture.

Kitchen Equipment

Commercial ovens, dishwashers and other fixed kitchen equipment may need assessment outside the ordinary PAT programme.

Workshop Equipment

Fixed tools and machinery should be reviewed according to their connection, construction and working environment.

Heating Equipment

Storage heaters and similar fixed equipment may require inspection that includes the appliance rather than only the supply circuit.

Other Hard Wired Equipment

A room by room survey can identify appliances that are connected through isolators or fused connection units.

PAT Testing, Fixed Appliances and EICRs

Understand Which Service Covers What

The three services assess different parts of workplace electrical safety. Defining those boundaries helps avoid missed equipment and duplicate work.

PAT testing covers portable and moveable equipment within the agreed programme

Fixed appliance testing assesses suitable hard wired or secured equipment

An EICR assesses the condition of the building electrical installation

The connection point should be identified before deciding the testing method

Visual inspection remains an important part of equipment assessment

The programme should reflect equipment risk and previous findings

A Practical Testing Process

From Equipment Review to Clear Records

The exact tests depend on the appliance and connection, but the management process should remain clear and traceable.

01

Identify

Confirm the equipment, connection method, location and available manufacturer information.

02

Plan

Agree access and any isolation needed to assess the equipment safely.

03

Inspect and Test

Complete suitable visual inspection and electrical tests according to the equipment and competent assessment.

04

Report

Record the item, result, finding and any recommended next action.

Testing Frequency Should Reflect the Equipment

There is no single interval that suits every appliance. Equipment type, environment, movement, use, manufacturer information and previous findings should inform the maintenance approach.

Frequently Asked Questions

Clear Answers Before You Book

A fixed appliance is generally equipment connected directly to the electrical installation through a fused connection unit, isolator or another fixed connection rather than an ordinary plug and socket.

A hand dryer that is wired directly into the installation is normally considered within fixed appliance assessment rather than ordinary portable appliance testing. The connection should be confirmed before the scope is agreed.

An EICR assesses the condition of the fixed electrical installation. A connected appliance may need a separate assessment to cover the equipment beyond its connection point.

No universal annual interval applies to every item. The maintenance approach should reflect the equipment, environment, use, manufacturer information and previous findings.

The record should identify the equipment, location, inspection or test date, result and any finding that requires further action. The exact document format depends on the agreed scope.
