I’m a long established (20+ years) hard working Narrowboat Electrician and take pride in my work. I really enjoy my job particularly the specialist work I get involved in. I’m only interested in working for customers who appreciate me & my approach and share my values. 

Checkout my new Instagram account which illustrates the type of the work I’m getting involved in.

I’ve made the decision to focus on my 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 my work is done to the very highest professional standards using only the best parts and equipment. 

Based from my workshop near Leek, Staffordshire, my central location covers many popular canals and marinas. And I am fully insured to work in any Boatyard or Marina.

Call Ed Shiers 07922 163072. fourcountiesmarineservices@gmail.com Please only call to make initial contact. If I don’t answer send a text or WhatsApp message and I will always call back ASAP. It’s just me and I’m always busy so most jobs need to be booked in well in advance. Breakdown jobs which include a callout fee can occasionally be done at short notice.
