Sized for the load, now and later

We size cables for the actual load, the run length and voltage drop, and allow for growth where you tell us it's planned, so you don't have to run it again next year.

Neat, protected runs

Cables go in tray, conduit or underground as the site needs, clearly labelled at both ends.

    You get a clear, written price before any work starts. No hourly meter running, no surprise bills.

  3. 3

    Job done properly

    Turned up when we said, done safely, tested, and cleaned up after.

The Coast Electrical promise

No surprises. No mess. No chasing.

Fixed price, in writing

You know the price before we start. If something changes, we talk to you first.

We turn up when we say

And if something holds us up, we call you before you have to chase us.

Clean and tidy

We clean up and take our rubbish with us. You won't know we were there, except it all works.

Workmanship guarantee

If anything we did isn't right, we come back and fix it free for 12 months.

Common questions

Do I need sub-mains for a new shed or workshop?

Usually, yes, if it will have its own sub-board for lights, power and equipment.

Can you run sub-mains underground?

Yes. We trench or use existing conduits, with the right depth and marker tape.

Do you liaise with the network for new supply?

Where a job needs a supply upgrade, we'll explain what's involved and who needs to do which part.
