PAT testing

PAT or PA testing is the mainstay of Greenhill's testing business. All portable electrical equipment should be tested yearly (PAT stands for Portable Appliance Test). We offer an outstanding service and great prices.

We provide all standard PA test services and also some specialist services:

  • Testing overnight to minimise office/venue downtime

  • Single item tests (you come to us)

  • We also specialise in audio visual equipment testing - contact us for more details.

We can test and certify your hearing loop to make sure it conforms to the IEC 60118-4 Standard for performance. Hearing loops often fail over time and go unnoticed, or sometimes are not tested after installation.


Our professional and friendly testing service will help you fulfil all your legal requirements for hearing loops and give you peace of mind.


Discounts are available for repeat tests (e.g. yearly).
