Why Choose Us? Why Are We Different?
Most electrical testing companies look the same on paper. Same services, same claims, same language on every website. What actually separates one company from another is what happens on the day, how the Engineers conduct themselves on site and what you are left with when the job is done.
Here is what working with TISS actually looks like.
Engineers Who Work As One
Our Engineers are not strangers brought together for a job. They have worked alongside each other for years and that shared history shows in how every visit runs. No miscommunication, no inconsistency and no one learning the ropes on your site.
We have successfully completed testing programmes ranging from 5,000 to over 300,000 individual tests across the UK. Large sites, complex layouts, tight deadlines. We have been there and we know how to handle it.

Complete Transparency On Every Job
Before work begins you will know exactly who is coming to your site. Every Engineer carries a personalised ID pack containing their full name and photograph, qualifications, calibration certificate, insurance details and Enhanced DBS number.
If we are working with your clients on your behalf, our Engineers represent your business. They carry your brand, follow your standards and conduct themselves accordingly. You will receive a digital pack in advance containing everything you need to know about who is attending.

What The ID Pack Contains
- Full name and photograph
- Qualifications and DBS information
- Insurance and calibration documents
No surprises on site and no questions about who is there or why.
Clear Reports, Sent Securely
Once the job is done your final report, photographs, notes and any advisories are zipped and sent securely by email. Everything you need for your compliance records in one place. If you need a free unzipping tool we can send you a download link.
We are not here to tick boxes. We are here to do the job properly and leave you with something you can actually use.
