What sits behind the meter in a Holywell home
A hamlet of this size is made up of individual houses rather than estates, each built and altered at its own pace. That shows on the board: we expect cartridge fuse boxes in some homes, early plastic units with a single RCD in others, and a few that have gained extra switches over the years for a shower, a kitchen extension or a garage.
Whatever is there now, the new board is chosen to suit the house. Dual RCD boards begin at £425, but for £625 upwards a full RCBO board stops one fault switching off half the home, which counts for more out in the lanes when the nearest help is a drive away.
- Old fuse carriers removed
- Extra switch boxes tidied away
- Main bonding to gas and water checked
- Circuit chart written up for you

When your earth comes from a rod in the garden
Out in the lanes beyond Lindfield, many properties are fed by overhead lines from UK Power Networks, and on those supplies the earth often comes from a metal rod set into the ground at the house rather than from the network cable. This is called TT earthing, and it depends entirely on RCDs to cut off a fault quickly.
With every board change we find the rod, check its clamp and conductor, and measure its resistance. If the reading is poor or the rod cannot be found, we tell you before any work starts, and the new board gives RCD protection to every circuit, which a TT supply needs.
- Earth rod located and inspected
- Resistance measured and recorded
- RCD cover on every circuit
- Findings explained before work starts

Asked in Holywell
Call for a straight answer from an installer, not a call centre.
Call 0333 360 8691Look near your meter. If the main earth cable disappears through the wall or floor instead of connecting to a clamp on the incoming supply cable, there may be a rod outside. The simplest way is to text us a photo of the meter, the main fuse and the board. We can usually tell from that, and we confirm it with a test on the day.
If the rod is corroded, loose or gives too high a reading, it has to be put right before the new board can be signed off. We explain what we found and give you a price before doing anything. Often the fix is straightforward, such as a new clamp, a new conductor or an additional rod.
Yes. Replacing a consumer unit is notifiable under Part P of the Building Regulations, so we notify Building Control on your behalf. Within two days you have our Electrical Installation Certificate in your email, and the compliance certificate follows later. Keep both with your house documents, because a buyer's solicitor will usually ask to see them.
