Started on the tools. Now delivering advanced PPM & PC projects.

ADS began in 2004 as a small electrical firm working across Preston and South Ribble. Clients kept asking whether we could look after the mechanical side too — the boilers, the ventilation, the hot water plant. So we trained, recruited and built the second half of the business.

Today we deliver planned preventative maintenance contracts and act as principal contractor on projects nationwide. The work has grown; the way we run it hasn’t. Engineers are employed, not agency. The person who surveys your site is the person who signs off the plan.

We are based on Dollywaggon Way in Bamber Bridge, which puts a van on most sites in Lancashire well inside our four-hour response commitment.
