Fuse box upgrade in Aberdeenshire, for the boards a city electrician rarely sees.

Not automatically, but they are assessed together as one installation. A farmhouse with a board in the house and another in the steading or workshop is common here, and each board is inspected on its merits. Sometimes only the main board needs replacing, sometimes an outbuilding board is the priority. We look at the whole installation and tell you what actually needs doing rather than replacing everything by default.

It means your property has its own earth rod rather than an earth from the network, which is common where the supply comes in overhead. Because the earth fault path runs through the soil, ordinary breakers cannot clear a fault quickly enough on their own, so the whole installation relies on RCD protection. We fit every circuit on an RCBO and, on many TT properties, a 100 mA time delayed main switch so the board discriminates properly and one fault does not black out the whole place.

It is strongly worth it. Surge protection is now the default on a new board unless a risk assessment allows it to be omitted, and an overhead rural supply is more exposed to lightning and switching surges than an underground one. It protects the things a modern home depends on, such as heat pump controls, an EV charger and anything with electronics in it. We will tell you honestly whether your situation justifies it.

For an ordinary home, no. Arc fault detection devices are only a requirement in specific higher risk premises such as houses in multiple occupation, purpose built student accommodation, care homes and higher risk residential buildings. For a normal farmhouse or cottage they are a recommended option you can choose to add, not a legal must, and we will not pretend otherwise.

We try to find that out before we start, which is why we assess and test before giving a firm quote. Older rural wiring sometimes hides borrowed neutrals or lighting circuits with no earth, which a modern RCBO board will not tolerate. Where that turns up, the honest answer is that some remedial work or a partial rewire is needed first. We will set that out clearly rather than discover it with the old board already off the wall.

For a straightforward change we isolate the supply safely ourselves. The main fuse and cut out belong to SSEN, the network operator, so where the main fuse rating, the meter tails, the cut out or the main earthing need attention, they are the party to involve. On a rural upgrade that is a normal part of the job and we coordinate it for you.

The power is off for the changeover, usually a few hours rather than the whole day, and most straightforward upgrades are a one day job. On a larger rural installation with several boards it can take longer, and we will give you a realistic timescale at the survey so you can plan around it, especially where there are freezers or water pumps to think about.

Usually yes. An EV charger and a heat pump both need a spare way and enough capacity on the board, assessed against the property's maximum demand, and an old full board has neither. The sensible approach is to size the new board once for what you are planning to add, rather than upgrade it twice. We can scope the board and the charger together.
