PAT Testing (now ITEE)

Why Has The Name Changed? Because electrical safety is no longer optional. The term “PAT Testing” was misleading and gave the impression only portable items needed checking. That’s no longer acceptable.

Here’s what sets us apart…

TISS Electrical – Electrical Testing & Compliance Services

Working to the latest 18th Edition BS7671:2018+A2:2022 standards.

TISS Electrical provides ITEE testing, emergency lighting testing, RCD testing and fixed wire testing for businesses across the UK. Whether you need 10 items tested or 250,000, we have the Engineers and the processes to handle it with minimal disruption to your business. We have successfully completed jobs ranging from 1,000 to over 250,000 individual tests and this is what we do every single day.

A Nationwide Electrical Testing Company

With offices in Chelmsford, Cambridge, Ipswich and Sheffield, we provide experienced teams of 2 to 20 Engineers across the UK. Every Engineer works together throughout the year, not just when a big job comes in. That consistency shows in the quality and efficiency of every visit.

Limited access? Only have the caretaker available for two days during half term? We have been there and we know exactly how to work around it. Every site presents different challenges and we bring the experience to handle them without fuss.

High Volume Testing

One or two testers would take weeks to complete 5,000 tests at a university. Our coordinated teams work together year round so large jobs get completed accurately and on schedule without anyone cutting corners.

We use Bluetooth data loggers on every job which eliminates manual data entry on site. Large projects are managed with shift based working to keep everything moving and flexible planning so we can adapt when things change.

Need to Split Testing Over the Tax Year?

Many clients opt for a 50/50 split, testing half in March to use up the current year’s budget and the other half in April for the new financial year. We arrange this regularly for education facilities and it works well for everyone involved.

Why Choose TISS Electrical?

Here is what you get on every job.

  • Teams of 2 to 20 experienced Engineers
  • Bluetooth data logging included at no extra cost
  • Photographic evidence of every failed item
  • Free advisory photos of anything else we spot on site
  • Clear reports and certificates written in plain language
