Eighteenth Edition BS7671

Appleby Electrical is now fully qualified to the latest 18th Edition wiring regulations.

Some of the big changes are –

lighting circuits in domestic dwellings must have additional protection by RCD or deemed as potentially dangerous.

split load consumer unit – the circuit breakers to the right of the blue switch are non RCD protected. (usually lights / cooker / immersion heater / boiler). The circuit breakers to the left of the switch on the right with the yellow test button are protected by RCD (sockets / shower etc). This consumer unit would now need to be upgraded and replaced.


Surge protective devices are being introduced at the origin of the installation – either by way of it’s own enclosure or within a new consumer unit / distribution board. This is down to all the expensive vulnerable electrical equipment that can be damaged from power surges – including in domestic dwellings (boiler’s, computers, Tv’s, game consoles sky boxes etc).

A home in the uk – 20 houses on the same street all had a power surge at the same time.
A SPD (surge protective device ) would have prevented this from happening .

There’s also the introduction of Arc fault detection devices to cosumer units to prevent dangerous electric arcs.


A consumer unit in Bradley, Hudddersfield last year. Could have done with an arc fault detection device!
