About us

In 1976, Trevor Walston left Esso Petroleum and became Operations Director of Dewco Services Limited, a company based in London and Ringwood, which specialised in the design, installation and maintenance of centralised oil distribution systems for housing and industrial estates.

Trevor formed a heating division in 1978 and, in 1980, he left and formed Dewco Limited in order to specialise in the design and installation of mechanical building services. The base was initially at Ringwood, and moved to Bournemouth in 1982. The Company subsequently returned to Ringwood in December 2004.

Much of Dewco’s success is due to its policy of employing a direct labour force that is fully trained together with a dedicated staff with many years of service. Our Contracts Director was our first fitter in 1979, and became a foreman in 1980. One of our Project Managers, with over 20 years of service, joined as an apprentice and became a foreman, before his present appointment. The other Project Manager, now with over 40 years experience, joined us in 1980. Our Contracts Supervisor, has also been with us for over 20 years progressing from fitter to foreman to his present position.

The company is now in the hands of Trevor's son, Robert Walston, although Trevor is still involved as Executive Director.
