Specialists in the maintenance, testing and inspection of electrical installations

ETTS is a Pembrokeshire based company specialising in electrical installations; from commercial and industrial installations, through caravan parks and filling stations to armouries and oil seperators, we look after them all.

Started in 1953 by Colin Butherway, the business has evolved over the years to become the specialist contractor it is today.

From wiring Roch Castle back in the 1950’s, through all electrical installation, refrigeration, as well as appliance sales and repairs, the business now specialises in Electrical Testing and Maintenance of electrical installations. We at ETTS can look after your equipment to ensure both compliance with current legislation, and efficient and reliable operation. Whether a full maintenance and compliance contract to one-off repairs and testing, we are here for you.

At the core of ETTS are our directors, both JIB-qualified electricians, who bring over 50 years of combined experience to the table.
