Meet Gary..
Professional electrical safety testing with a friendly, personal approach built around your business.
I began working in the electrical industry at Heathrow Airport when I was just 18 years old and now have over 25+ years of practical experience helping businesses stay safe and compliant.
After being made redundant during the pandemic, I saw an opportunity to use my knowledge to support local businesses, schools, landlords and organisations with professional electrical safety testing.
That decision became GT PAT Testing & Maintenance.
Today I work with schools, nurseries, care homes, hotels, offices, landlords, restaurants and commercial businesses across London and the surrounding Home Counties.
My aim is simple...
To provide a reliable, friendly service with minimal disruption to your business and complete peace of mind.
