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:
- Lithium systems. Strong, reliable, rugged and safe LiFePO4 based power.
- Custom alternator & charging system upgrades: Primarily for lithium – enabling powerful and unstrained charging.
- External alternator regulators: Total alternator control. Superfast, optimised, reliable lithium charging with BMS integration.
- Top quality solar power installations: Panels mounted flat tightly against the roof on my stainless steel bracket set. 180 degree tilt option.
- 3.5 Travel Power generators.
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.
