About Cosgrove & Drew

Cosgrove & Drew offer a wide-range of mechanical services, from domestic heating and plumbing installations to large commercial plant rooms and everything in between.

Our founders, Zac (Cosgrove) and Luke (Drew), are the drivers behind the company’s success, comprising a team of two engineers who have quickly embedded themselves into the world of business from the manual labour and tools environment. Their own development has enabled the company to grow rapidly over the last 5 years from a team of 2 to 48, while our customers recognise and recommend us for collaborative working practices, excellent service, and quality of workmanship.

Cosgrove & Drew boast an unrivalled passion for supporting our hardworking and dedicated workforce. Our award winning team is made up of highly skilled industry specialists alongside driven apprentices that form the foundations of a promising future for the business and our industry.

who we work with

Since we began back in 2014, we have had to build our client base from a name nobody had ever heard of to a position where we feel our client base and reputation within the industry is second to none.

The ability to work collaboratively with our clients to deliver bespoke and complex solutions sets us aside from our competitors; we treat our clients as we would our own employees – with respect, an honest approach, and while always striving for the best outcome.

We provide expert mechanical engineering services to the following sectors:


"I have subcontracted elements of multiple M&E projects to Cosgrove & Drew over the last 3 years ranging in value from £10k to £500k and have always been impressed with their professionalism and dedication to delivering a first class service and end product. As with all projects we have faced a number of challenges, both anticipated and unexpected and in all circumstances Cosgrove & Drew have worked collaboratively and without alternative agenda to overcome the issues and deliver the project on time and to a very high standard. In my opinion this is what sets Luke & Zac apart from other contractors."
