MJN Colston has over 500 directly employed staff and craftsmen who work from our offices in Croydon, Bristol, Bridgend and Exeter. Our people, the majority of whom are long serving, take great pride in the quality of our work and this underpins everything that we do.
Our Company is controlled by a Management Board with each and every project assigned to a Contracts Director who has responsibility for your project from inception to completion. The level of repeat business we enjoy is testimony to our non-adversarial approach to our dealings with customers.
Our history goes back to 1890 when Marryat and Place was formed. Marryat and Place joined with Norris Warming and Jackson in 1968 to become MJN. The Colston Electrical Company was formed in 1926 and was merged with MJN in 1982 to form MJN Colston. Our company has a fine heritage of which we are justifiably proud. We believe that our tradition for quality workmanship, combined with our commitment to innovation and continuous improvement, gives us a sound platform for future progress.
