About Us

We are a family-run business established by Callum (our Managing Director) and we have more than 50 years of experience between our highly qualified team of experts. Since the company began, we’ve worked across every conceivable sector from newly built housing projects to huge commercial and industrial businesses. There’s no electrical contracting service we can’t provide.


Who Are We?

We are NAPIT-approved contractors (a government-authorised accreditation service) meaning we are fully qualified for any electrical work, ensure compliance with regulations and hold the relevant insurance. Our teams are all highly trained and CHAS-certified (Contractors Health and Safety Assessment Scheme) as well as holding DBS certification and IPAF (International Powered Access Federation) cards for safe working at heights.

We are a company that is fully dedicated to customer satisfaction and top-quality results. We take pride in delivering meticulous work with integrity throughout the West Midlands and across the country. We’re excited to see how far we’ve come, and we’re aiming to continue our rapid growth and success in the years ahead.
