1980s Oil Boom Estates
The first wave of Kingswells family homes, now around 40 years old. Original boards are typically rewireable or early plastic. Full RCBO upgrade is the usual outcome.
Faithful Spark Electricians upgrade the fuse boxes across Kingswells, from the original boards in the 1980s and 1990s estates off the A944 to neat additions on the new build plots at Countesswells and The Reserve at Eden. Modern metal enclosure, an RCBO on every circuit, surge protection fitted as standard, and a clean BS 7671 certificate. Every board led personally by Steven Watt.
Kingswells sits about five to six miles west of Aberdeen city centre, north of the A944 and east of Westhill across the AWPR bypass that opened in 2019. Around 5,000 people live here, many commuting the short hop to Prime Four Business Park. Unlike the granite tenements closer to town, almost every Kingswells home is modern brick and render that went up from the 1980s onward, so these are not period properties. They are estate houses now roughly 35 to 45 years old, which is exactly the age where the original consumer unit, often an early plastic board with limited or no RCD protection, has earned a replacement. A modern RCBO board to the 18th Edition is the fix, and Steven Watt fits every one himself.

A modern RCBO board in a Kingswells home. Every circuit gets its own breaker, so a fault on one no longer blacks out the house.
A consumer unit does not have to be sparking to be worth upgrading. On a 1980s or 1990s Kingswells estate home, any one of these is reason enough to book a survey.
A board with porcelain carriers and lengths of fuse wire instead of breakers. No RCD, no overload protection beyond the wire melting.
The original cream or grey plastic board common to estate homes of this era. The 18th Edition now expects a non combustible metal enclosure.
No test button, or a single device covering everything. RCD protection is what disconnects the supply before an earth fault becomes a shock.
An inspection report listing C2 codes against the board. A single board upgrade often clears several of those codes at once.
Frequent nuisance tripping, brown scorch marks at a terminal, or a faint burning smell. Switch off the main switch and call us the same day.
A new charger, a renewables install, a rewire, or a renovation that adds circuits often needs the board upgraded at the same time.
Kingswells is not one age of housing. Where your home sits on this timeline is the single best clue to what is behind the fuse box door.
The first wave of Kingswells family homes, now around 40 years old. Original boards are typically rewireable or early plastic. Full RCBO upgrade is the usual outcome.
The second estate wave. Often an early plastic board with a single RCD covering some circuits and not others. An EICR or an EV install commonly tips these into an upgrade.
The newest Kingswells plots. These usually already have a modern RCBO board, so no upgrade is needed unless you are adding a heavy new load such as a charger.
Newer terraces and the rentals scattered across the suburb. Where a board is flagged on a landlord EICR, we carry out the upgrade and reissue the certificate.
A consumer unit, a fuse board, and a fuse box are all the same thing. It is the unit that takes the incoming mains supply and distributes it to the individual circuits around your Kingswells home, the cooker, the shower, the sockets, the lights, an EV charger if you have one. Just as importantly, it protects each of those circuits against overload and earth faults, which is your first line of defence against an electrical fire or a shock.
A board built to the current BS 7671 18th Edition has four things an older estate board usually lacks. A non combustible enclosure, which in practice means metal rather than plastic. An RCBO on every circuit, combining overload protection and earth fault protection in one device. A surge protection device (SPD) to guard sensitive electronics against transient spikes. And, where it is appropriate to the circuit, an AFDD to detect arcing faults before they can ignite.
The practical win for the homeowner is simple. On an old board, one earth fault can take out half the house through a shared RCD. On a full RCBO board, only the single faulty circuit trips and the rest of the house carries on.

When the Kingswells estates went up through the 1980s and into the 1990s, the boards fitted as standard were either rewireable wire fuse units or early plastic consumer units. Both were perfectly normal for their day. Neither matches what the 18th Edition expects in 2026, and after roughly four decades of service the components themselves are simply tired.
What the original estate board often cannot do:
A straight swap for a modern Hager or MK RCBO board takes one to two hours on site for a typical Kingswells supply, and starts at £550 + VAT. We test every circuit afterwards and hand you a BS 7671 certificate.

Kingswells is a suburb of off street driveways and commuters, so home EV chargers are everywhere here. An EV charger needs its own dedicated 32A circuit with the right RCD protection. On a modern board, that is a simple addition in a spare way. On an original estate board it is rarely that tidy.
An older single RCD can be too quick to trip on the rapid switching of a charger, which then takes out half the house every time the car is plugged in. Many of these boards also have no spare ways and no provision for a modern charger circuit. In those cases the honest answer is to upgrade the board alongside the charger.
We offer bundle pricing for exactly this, a full board upgrade fitted together with the EV charger from £750 to £1,000 + VAT. One visit, one set of testing, one certificate, and no second call out when the board would otherwise have struggled with the new load.
See our wider EV charger installation service or the dedicated EV charger in Kingswells page for the charger detail.

If an EICR on your Kingswells home or rental has flagged the consumer unit, a full board replacement is usually the fastest and cleanest remedy. A single visit can resolve several C2 codes together, gives you a fresh certificate that supersedes the old report, and brings the installation up to the current regulations in one move.
The board related findings we see most often on Kingswells estate homes:
For landlords, we can pair the board upgrade with the full EICR retest in the same visit. The detail of the inspection itself lives on our EICR in Kingswells page, and the wider service on the consumer unit replacement page.

An older board usually warns you before it fails, but the signs are easy to live with for too long. In every case the right response is the same. Turn off the main switch and call a qualified electrician the same day.
If you see any of these in your Kingswells home, switch off at the main switch, the largest switch in the centre of the board, and call us on 07304 027013. We can usually attend the same working day for an urgent board fault.

The same clear process whether it is an original 1980s board or a tidy addition on a newer plot.

Call 07304 027013Wondering whether your board has actually earned a replacement? Our guide on whether a consumer unit upgrade in Aberdeen is worth it is a useful read before you call.
The qualification that matters most for a consumer unit is BS 7671, the wiring regulations a board is certified against. Steven Watt holds the City and Guilds 2382-22 award in BS 7671 18th Edition, backed by his Level 3 Diploma in electrical installations and his inspection and testing award. These are individual City and Guilds qualifications, held on top of our NICEIC approved contractor status.
Anyone can claim to be qualified. Steven's City and Guilds awards are genuine and named to him, not decoration.



A consumer unit upgrade is one of the riskier jobs an electrician does. The supply stays live behind the main switch even when the switch is off, the order of terminations matters, and the wrong device type can leave a circuit unprotected. It is not a job for a handyman or a weekend favour.
Every Faithful Spark board is signed off with a BS 7671 Electrical Installation Certificate that carries our NICEIC registration. That certificate is what insurers, letting agents, and Aberdeen City Council want to see. Our registration is publicly searchable, and we will always show you the qualifications behind the work.

Very likely worth a look. Most original boards from that era are rewireable wire fuse units or early plastic boards with limited or no RCD protection, and after 35 to 45 years the components are tired. The clearest signs are nuisance tripping, scorch marks, no test button, or a home that blacks out fully when one appliance faults. We test the existing installation first, then advise honestly. A full RCBO upgrade in Kingswells starts at £550 + VAT.
Usually not. The newer Kingswells plots are typically fitted with a modern RCBO board already, so there is nothing to change unless you are adding a heavy new load such as an EV charger or a renewables system. We are happy to confirm what is behind your board on a quick free survey rather than have you guess.
Yes. Consumer unit, fuse board, and fuse box are three names for the same thing, the unit that distributes the mains supply to your circuits and protects each one. The word "fuse box" stuck from the era of wire fuses. A modern equivalent uses an RCBO on every circuit instead of a fuse, in a metal enclosure to BS 7671.
It depends on the existing board. On a modern board it is often a simple addition in a spare way. On an original estate board, a shared RCD can trip every time the car plugs in, and there may be no spare ways for a charger circuit. Where that is the case we fit the board and the charger together, bundled from £750 to £1,000 + VAT, in a single visit.
Not long. A typical Kingswells board takes one to two hours on site in total, and the supply is off the main switch for roughly the middle hour of that while we move every circuit onto its new RCBO. We then test everything and energise. We agree the timing with you up front so it fits a Prime Four working day.
A board properly installed and certified by a NICEIC approved contractor is universally accepted by UK home insurers. We provide a BS 7671 Electrical Installation Certificate at completion. The opposite is the risk, an uncertified or DIY board can invalidate cover, so the certificate matters as much as the board itself.
