Whether you run a business around Dovercourt High Street or a busy warehouse near Europa Way, our engineers work through your site with as little disruption to the working day as possible.

TISS Electrical carry out certified PAT testing for businesses across Harwich, keeping offices, warehouses, retail units and commercial premises compliant throughout the year.
Harwich has a strong port and industrial side, with employment sites around Europa Way and the A120 supporting warehousing, logistics and other industrial uses connected with the wider port economy. Dovercourt High Street serves a different mix of local businesses. A warehouse or industrial site can have very different testing requirements from a High Street business, so our engineers plan each visit around the equipment you actually use.
Get in touch through our contact form and we’ll confirm what your premises needs and when your next test is due.

- Clear next steps for any item that fails, whether that’s a repair or a replacement
How Often Does Equipment Need PAT Testing?
It depends on the equipment and how hard it’s used. The IET Code of Practice for In-Service Inspection and Testing of Electrical Equipment sets out suggested starting intervals. Hand-held tools and extension leads used daily on a warehouse or workshop floor may need testing every 3 to 6 months, while office IT equipment that rarely moves can often go well over a year between tests. Your risk assessment sets the final schedule, and we’ll recommend intervals for your site after the first visit.
Is PAT Testing A Legal Requirement?
Not by name, but the duty behind it is. The Electricity at Work Regulations 1989 require employers to keep electrical equipment maintained so it doesn’t cause danger, and the Health and Safety at Work Act 1974 and PUWER 1998 add wider duties to keep work equipment safe. The law doesn’t set a testing method or a fixed interval, so most businesses use regular PAT testing as the clearest way to show they’ve met that duty.
An up to date test record is also useful evidence if an insurer or inspector asks how your equipment has been maintained.
What Happens If An Item Fails?
If an item fails, it’s marked on your report with an advisory photo showing which item it is and where it’s kept. It won’t be labelled as passed while the fault is still there, and we’ll tell you whether it needs repairing or replacing before anyone uses it again.
