Lights back on today.

I start at the board and work outwards with a clamp meter and an insulation tester. Most faults are found inside the first hour. If it runs longer I phone you before the hour is up and tell you what I have found and what it will cost to finish.

A new board, earth leakage, surge protection, and every circuit on its own labelled breaker. The price moves with the number of circuits and whether the house needs rewiring behind the board. You get the figure before I order anything.

Required when a property is sold, and valid for two years. I inspect, then send a written list of what does not comply with a price against each item. You decide what to do. The certificate is issued once the list is cleared.

Chased into the wall and plastered, or surface trunking if you would rather not open walls. Outside work goes into weatherproof housings. I take the old fittings away with me.

The essentials go onto their own board, so the inverter is never asked to carry the geyser or the stove. Installation only: you buy the inverter and the batteries yourself, which is cheaper than buying them through me.

Shopfitting, lighting changes, extra circuits for equipment. I work after closing if the shop cannot lose a trading day, at no extra rate on weekdays.
