How to Build an Appliance Inventory and Asset Register Before PAT Testing Begins

Creating an accurate appliance inventory and asset register before PAT testing is the most effective way to streamline the testing process, reduce downtime, strengthen compliance and ensure nothing is missed. A well-structured register helps you manage risk, prioritise high-risk equipment, track asset history and demonstrate your duty of care.

This guide explains the purpose of an appliance inventory, what information to include, how to build one step-by-step and how Global Compliance UK supports you throughout the process. If you'd like to arrange a visit or discuss your testing needs, please use the contact page.

Why an Appliance Inventory Matters Before PAT Testing

Building an inventory is more than a paperwork exercise. It is a safety tool, a compliance resource and a planning mechanism that ensures your PAT testing runs smoothly. An accurate and up-to-date register gives you full visibility of all the portable electrical appliances across your site, including the ones that are easy to overlook.

Supports Efficient and Accurate PAT Testing

A clear inventory ensures the PAT engineer can move through each area quickly and systematically. It eliminates guesswork, reduces missed items and allows the tester to prepare the correct equipment for different appliance classes. The result is faster testing and minimal disruption to workspaces, tenants or operations.

Strengthens Electrical Safety Compliance

UK duty holders are required to ensure electrical equipment remains safe for use. A documented asset register demonstrates that you are taking reasonable steps to comply with HSE guidance and managing equipment responsibly. It also helps you maintain consistent inspection and testing intervals.

Provides a Reliable Audit Trail

Many organisations, especially in housing, education and commercial workplaces, must provide evidence of appliance safety. An asset register becomes part of your audit documentation and allows you to track test dates, failures and repairs throughout the equipment lifecycle.

Improves Budgeting and Asset Management

Knowing what appliances you own, their age and their condition helps you plan replacements before faults occur. A register also prevents unnecessary PAT testing on outdated or unused equipment that should already be retired.

Reduces Risk Across the Workplace

Unlisted or forgotten equipment often goes untested, which increases the risk of electrical faults or fire. A complete register reduces these blind spots and ensures every appliance is included in safety checks.

What Your Appliance Inventory Should Include

A strong inventory captures detailed information about each piece of portable electrical equipment. It must be clear, consistent and structured in a way that supports future PAT cycles.

Core Information for Each Appliance

Your asset register should include:

• Item description such as “Desktop computer” or “Toaster”

• Unique ID or asset tag to link the physical item to the register

• Location including building, floor and room

• Department or owner if applicable

• Appliance class such as Class I or Class II

• Voltage for example 230V

• Plug type and fuse rating

• Serial number or model number

• Condition notes for visible wear, damage or previous issues

• Date added to inventory

• Date last tested or inspected

• Next due inspection/test date

• Access notes such as "kept in locked cupboard"

Including these fields helps streamline testing, avoids duplicate entries and improves record accuracy.

Optional but Useful Information

Additional fields can strengthen long-term asset management:

• Manufacturer and model

• Purchase date or installation date

• Estimated replacement year

• Risk rating based on usage, environment and movement

• Maintenance history

• Test outcomes for pass, fail or repair

• Disposal or retirement date

These fields are particularly useful for organisations with a large number of appliances across multiple sites.

Step-by-Step Guide to Building Your Inventory and Asset Register

Creating an asset register may seem like a large task, but following a structured process turns it into a manageable and effective exercise.

Identify All Portable Appliances Across Your Site

Start with a walk-through of the entire premises. Include all rooms, storage areas, staff-only areas and tenant-occupied spaces if applicable. Portable appliances are not just obvious items like kettles or fans. They include:

• Chargers

• Extension leads

• Desktop equipment

• Portable tools

• Kitchen appliances

• Cleaning devices

• Heaters

• Lamps

• Audio-visual equipment

Everything that plugs into the mains or is powered through a portable supply should be included.

Record Key Information Immediately

As you identify each appliance, collect its essential details in your register. Using a mobile device or tablet can make this process much faster. Begin with the basic fields:

• Description

• Location

• Class

• Condition

• Unique ID

Once these are captured, you can refine and expand the data later.

Assign Asset Tags or Labels

Attach a durable tag or label to each item. This ensures the appliance can be correctly matched to its entry in the register. Tagging also prevents duplication and confusion, especially in environments where equipment moves between rooms or departments.

Labels should be clear, consistent and placed somewhere easy to see but not easily damaged.

Group Appliances by Area or Category

Organising appliances makes future PAT testing faster and reduces downtime. You can group items by:

• Room or floor

• Department

• Voltage type

• Appliance class

• Risk rating

Grouping also helps with scheduling. For example, you may decide to test all kitchen appliances on the same day or focus on high-risk workshop tools first.

Identify High-Risk and Low-Risk Equipment

Not all appliances need the same level of testing or the same frequency. As you record each item, assign a simple risk rating based on factors like:

• How often it is used

• How often it is moved

• Who uses it

• Environmental exposure such as dust, heat or moisture

Hand-held tools, extension leads and frequently transported equipment are typically high-risk. Office monitors or desktop printers are usually low-risk.

Risk classification helps you build an efficient testing strategy.

Note Any Faults or Damaged Items

If you identify damaged appliances during your inventory walk-through, make a note of them and remove them from service until inspected. Examples include:

• Frayed cables

• Exposed wiring

• Cracked plugs

• Burn marks

• Overheating smells

• Loose components

Logging faults early prevents unnecessary testing and improves safety immediately.

Decide on a Register Format

You can create your register using:

• A spreadsheet

• Asset tracking software

• A cloud-based facilities management platform

• A PAT testing management tool

Small businesses often start with a spreadsheet, while large organisations may prefer dedicated software that supports scanning, tracking and automated reminders.

Review and Update the Register Regularly

An asset register must be kept current. After PAT testing, update each entry with:

• Test results

• Date tested

• Next due date

• Repairs or changes

Your register should be reviewed whenever:

• Equipment is added or removed

• Tenancies change

• Faults are reported

• Sites are reorganised

The more accurate your register, the safer your workplace becomes.

Linking Your Register to PAT Testing

Your appliance inventory becomes a core part of your PAT testing process. Here’s how the two connect:

Helps PAT Engineers Plan Their Visit

Providing your register in advance allows your PAT provider to plan the visit properly. They can:

• Estimate the time required

• Bring the correct equipment

• Prioritise high-risk items

• Minimise disruption around busy areas

This saves both time and cost.

Supports Risk-Based Testing Intervals

HSE encourages a risk-based approach to PAT testing, and your register’s risk classifications help determine testing frequency. High-risk appliances may require annual or more frequent checks, while low-risk office equipment may only need periodic inspections.

Improves Documentation and Record-Keeping

Your register becomes the master record of all appliances. PAT results, labels and next due dates are recorded directly against each item, making future testing cycles easy to manage.

Highlights Trends and Recurring Faults

If the same appliance type fails repeatedly, or a specific room has multiple issues, your register will highlight this pattern. You can then implement targeted repairs or replacements.

Supports Safety Audits and Insurance Requirements

A complete and well-maintained register demonstrates that you are managing electrical safety responsibly. Insurers and auditors regularly ask for proof of testing and equipment history. Your asset register provides this instantly.

Common Mistakes to Avoid When Building Your Register

Even well-organised businesses encounter challenges when building their inventory. These are the most common pitfalls:

Missing Hidden or Low-Visibility Equipment

Items stored in cupboards, back rooms or tenant cupboards are easily missed. A complete walk-through prevents these gaps.

Using Inconsistent Naming or Labelling

If appliances are labelled inconsistently, your register becomes confusing and hard to use. Use a standard naming format throughout your inventory.

Failing to Remove Retired Equipment

Old or unused equipment often remains in registers for years. Remove these items to avoid unnecessary testing.

Not Updating the Register Regularly

A register is only valuable if it is accurate. Ensure it is updated after each PAT visit or equipment change.

Not Linking Testing Results to the Register

Your register and PAT testing schedule must connect. Missing this link reduces the value of both systems
