PAT Testing in Server Rooms

Share via:

If you have a server room or data center in your office building, you may need to know if the computer equipment in it needs PAT testing.

PAT testing is one of the best ways to identify faults with electrical equipment and ensure it stays safe. However, some electrical equipment is easier to test than others!

One of the questions we are frequently asked is ‘are server rooms exempt from PAT testing?’

If you’re unsure whether your server room needs PAT testing, we’ve put this guide together to help.

Are server rooms exempt from PAT testing?

It’s important to remember that PAT testing is not a legal requirement in offices and commercial buildings. However, it can be one of the most effective ways of ensuring electrical equipment stays safe in line with health & safety legislation.

The 5th Edition of the IET Code of Practice for In-Service Inspection and Testing of Electrical Equipment was published in September 2020. This code contains guidance about equipment racks and bays, like those found in server rooms.

As the equipment in server rooms is permanently mounted, it is at low risk of damage compared to other electrical equipment in an office building.

Equipment in server rooms is typically only removed when it is repaired or replaced. This is when damage is most likely to occur.

It’s recommended that equipment is tested before it’s installed in the server room to ensure a reliable benchmark.

If testing takes place, it’s vital for the person carrying out the work to be fully aware of the equipment they are testing. Any errors or damage can cause servers to shut down, causing inconvenience for staff and customers.

The need for risk assessments in server rooms

It’s recommended that businesses carry out risk assessments to determine how often PAT testing needs to be carried out in their server rooms

A risk assessment will take into consideration:

  • The current state of repair of the equipment
  • Who has access to the equipment and whether they have the technical expertise to maintain it
  • What maintenance programmes are currently in place, and how frequently they occur
  • How often the equipment is replaced or moved
  • What safety measures are in place, for example, RCDs

This will give your business the necessary information to identify how often PAT testing is needed. For most server rooms, PAT testing is typically carried out every two years, but this frequency can vary.

In summary: PAT testing can be of benefit for server rooms

We recommend that businesses carry out PAT testing for the electrical equipment in their server rooms, as malfunctioning equipment can overheat, causing fires and downtime.

However, as the equipment is static, it does not have to be tested often. A risk assessment will help you determine the right frequency for your business.

Electrical equipment must be turned off and unplugged during a PAT test. Some server rooms have a dual power source in the case of power cuts, which means the server can keep running. If not, PAT testing should occur during a time when the impact will be minimal, such as evenings and weekends.

Both very professional, approachable and very well organised, which made the whole process run smoothly. Everything was explained clearly, disruption was kept to a minimum, and it was obvious they take pride in doing the job properly.

Several people commented on how efficient and pleasant you were to deal with.

Thanks again for your hard work — it was genuinely appreciated. We would be more than happy to have the same engineers again next year.

I’ve been using Hawkesworth for over seven years across various businesses for PAT testing, and they have consistently delivered an outstanding service. The booking and planning team are always friendly, helpful, and efficient, making the process smooth from start to finish.
The engineers they send are professional, polite, and trustworthy, qualities that really matter when working on-site in financial businesses. Our regional office managers have repeatedly commented on how impressed they were with the care and consideration shown during testing, both for our property and our staff.
Hawkesworth truly go above and beyond to provide a turnkey solution that ensures PAT testing is carried out correctly and with minimal disruption. I would 100% recommend them to anyone looking for a reliable, customer-focused company.

Thank you, Hawkesworth!

As a new customer of Hawkesworth, I wanted to share my positive experience after using multiple services. From the moment I submitted an online enquiry, I received an immediate response—Debbie was incredibly helpful in explaining all the services Hawkesworth offers.

The follow-up process was seamless, with appointments scheduled promptly and honored as agreed. Every engineer who visited our site delivered exceptional service. They kept us informed about upcoming visits, arrived on time, and throughout the work, they were attentive to our company’s needs, going above and beyond to ensure excellent customer care.
The services provided included PAT testing, fire extinguisher checks, and emergency lighting inspections.

Based on this experience, I would highly recommend Hawkesworth to other businesses.

GeneFirst Ltd has been using Hawkesworth Appliance Testing for the last 2 years at our current site location.
Last year I had the pleasure of meeting Kobla Dogbatse the PAT engineer from Hawkesworth and he was fantastic.
Kobla, was efficient and thorough with his work, he was polite and pleasure to have on site.
He was respectful to all staff members by trying to limit any distraction or disturbance when conducting his work on any appliances that the team would be using.
This year I was lucky enough to have Kobla come back and I was thrilled to have him back as I knew the work would be done to the highest standards.
I allowed him to continue with his work without supervision and once finished he came into my office with a smile on his face and said everything is done and its all good.
I would highly recommend Hawkesworth to other companies as they are efficient with their communication and their engineers are a pleasure to have on site.
Thank you again for the great work and I hope to continue using your services in the future.
