This site isn’t updated regularly. My Instagram account https://www.instagram.com/four_counties_marine/ shows photos of recent jobs and gives a good idea of the type of work I’m getting involved in and what you can expect. Feed recently added to the bottom of this page.


I’m a long established (20+ years) hard working independent narrowboat electrician and take pride in my work. I’ve gained my knowledge, experience and reputation working with top quality Boat Builders and Boatyards and keep right up-to-date with the latest standards and developments in technology.

I specialise in work associated with power:

I’m properly setup with the tools, equipment & knowledge to tackle the jobs that I specialise in and work from a well stocked van & workshop. All of my work is done to the highest professional standards using top-quality parts and equipment.

Based from my workshop near Leek, Staffordshire, my central location covers many popular canals and marinas. And fully insured to work in any Boatyard or Marina. **Feb 2022. Now insured to work on coastal Yachts**

I no longer offer general electrical work and I’m concentrating on the jobs that I specialise in.
