How much does it cost to replace a consumer unit in Kingswells?
Most Kingswells homes come in between £550 and £950 + VAT. Where yours lands depends mainly on how many circuits the board feeds and how much tidying the surrounding wiring needs. Every figure on this page is before VAT. Our guide to how much a fuse box upgrade costs breaks it down by board type.

Why two Kingswells quotes differ
- Additions over the years. Conservatories, loft rooms and garage sockets each bring a circuit that needs its own device.
- Board position. A unit squeezed into a hall cupboard or garage corner is slower to change than one on a clear wall.
- Bonding. Missing or undersized earth clamps on the water or gas pipe are corrected while we are there.
- Meter tails. Tails that are old or too short for the new layout are replaced.
- Your plans. A charger, electric shower or heat pump on the horizon means we leave room for it now.

Is your Kingswells consumer unit due for replacement?
It is due when it has no RCD protection, still uses fuse wire, shows heat damage, or has no room for a circuit you need. Most of Kingswells went up from the 1980s onward, so many houses still run on the board they were built with, and those first boards are now old enough that an inspection tends to look hard at them.
| When the house was built | What we tend to find | What we usually recommend |
|---|---|---|
| 1980s estates | The original board, in some homes with no RCD protection at all | Replace the board. The cable behind it is often sound, so test it before anyone mentions a rewire |
| 1990s homes | A split load board with one or two RCDs, each covering a group of circuits, plus decades of extra circuits | Often compliant as it is. Replace for capacity, for a charger, or because one fault drops half the house |
| 2000s and later | A newer board with RCD protection and fewer surprises | Usually keep it. A new circuit generally fits a spare way, and we tell you when nothing more is needed |
Split load and dual RCD boards
A split load board shares two RCDs between banks of circuits. It still gives earth leakage protection to the circuits under each RCD, which is why it is not automatically a defect. The weakness is that one leaking appliance can trip every circuit on its side, so the fridge, the lights and half the sockets go off together. An RCBO on each circuit isolates the fault to one circuit instead. Our article on split load and dual RCD consumer units compares the two layouts.
Five signs a Kingswells board should go
- Rewireable fuse carriers instead of switches
- No RCD test button on the board anywhere
- Trips you cannot explain, or a hum from behind the cover
- No spare way left for an extension, shower or charger
- An EICR that names the board itself as a problem
Switch off at the main switch and call us if
- You see scorch marks or melted plastic on or around the board
- There is a smell of hot plastic near it
- It crackles, or a switch feels hot
Only reach for the main switch if it is safe to do so, then phone 07304 027013 during opening hours.
How long does a consumer unit replacement take?
Allow one working day in a Kingswells house. The electricity is off for roughly 4 to 6 hours of that, and if bonding, new tails or a board move will add time, the survey tells you before the day is booked.
- Readings from the old installation. We test the existing circuits while the old board is still in, so a cable fault is found before the swap rather than blamed on it.
- Power off, old board out. The supply is isolated, the old unit comes off the wall and the new enclosure goes up. Earthing and main bonding get checked at the same stage.
- Circuits connected one by one. Each circuit goes onto its own device and is labelled, with everything left off until tested.
- Testing. Continuity, insulation resistance, polarity, earth fault loop impedance and RCD operating times are measured and recorded.
- Power on and handover. The board goes live, you get the certificate, and we show you the main switch and how to use the test buttons.
On the day: keep the area around the board clear, and tell us in advance about anything that cannot lose power, such as medical equipment or a well stocked freezer, so the shutdown is planned around it. Expect to reset clocks, timers and the broadband router afterwards.
Has an inspection flagged your board?
Send us the report. We will tell you if the board needs a repair, a replacement or no work at all.
What the current wiring regulations mean for a Kingswells board
New boards are fitted to BS 7671:2018+A4:2026, the amendment published on 15 April 2026, which is still the 18th Edition. It sets the standard for the board going in. It does not force a working board out.
Metal for new installs
Regulation 421.1.201 calls for a non combustible enclosure, normally steel, on any consumer unit installed in a home. That applies at the point of fitting, so the plastic board you already have is not a fault because of it.
Arc fault detection
AFDDs are mandatory on socket circuits up to 32 A only in high rise residential buildings, HMOs, purpose built student accommodation and care homes. For a Kingswells house they are recommended, and we price them if you want them.
Surge protection
In a single home the owner can turn down a surge protection device, and that decision is recorded on the certificate. We suggest one, at £40 to £80 + VAT, where a home office, a heat pump or a lot of electronics are involved.
RCBOs throughout
Not a legal requirement. A dual RCD board still complies. We recommend RCBOs because a single fault then switches off a single circuit, and that is the whole argument.
No Part P in Scotland
National articles often say a new board must be notified under Part P or signed off by Building Control. Those are rules for England and Wales and do not apply in Kingswells. In Scotland the Building (Scotland) Regulations 2004 apply, including building standard 4.5 on electrical safety, with the domestic Technical Handbook pointing to BS 7671.
A like for like replacement of an electrical fixture is work that needs no building warrant under Schedule 3, type 24, provided the installation ends up no worse than it was. The work must still meet the regulations, the owner is responsible for that, and in Kingswells the authority is Aberdeen City Council.
Can I replace a consumer unit myself in Scotland?
You would struggle to do it in a way anyone could rely on. Isolating the board usually means removing SSEN's sealed main fuse, and SSEN's supply FAQ says electricians are not accredited to work on its equipment either. After that, every circuit needs testing with calibrated instruments and recording on an Electrical Installation Certificate, which is the document a buyer, insurer or letting agent will ask for.
Do Kingswells landlords need a new consumer unit?
Only where the main board has no 30 mA RCD protection. For a let property the Repairing Standard sets that minimum, and a working split load board will often already meet it.
The Repairing Standard wording
"there must be one or more Residual Current Device (RCD) with rated residual operating current not exceeding 30 mA in the main or principal consumer unit. Normally, as a minimum, this will cover the socket-outlet circuit."
Source: Repairing Standard statutory guidance, Annex D3, paragraph D.55.
What that means for your let
- No RCD on the main board: work is needed, and a new board is the usual answer.
- Split load with the sockets under an RCD: generally meets D.55.
- The guidance does not ask for an RCBO on every circuit.
- A new board does not replace the EICR you need every five years.
Not sure where the property stands? Book an EICR in Kingswells from £150 + VAT. Under BS 7671:2018+A4:2026 only C1 and C2 codes make a report unsatisfactory. C3 and FI are advisory, though an FI against the board in a rented home should still be investigated promptly.

Can I get a free consumer unit replacement from the government?
We have found no Scottish or UK scheme that pays for a consumer unit on its own. A free main fuse upgrade from SSEN is a different thing, and that one does exist.
What Home Energy Scotland covers
We read the Home Energy Scotland funding page on 6 October 2026. Its grants, loans and Warmer Homes Scotland help are aimed at insulation, heating and heat pumps, with nothing listed for consumer units or wiring. If anyone offers a Kingswells household a free board through a grant, ask which scheme is paying and check with Home Energy Scotland first.
SSEN and the main fuse
Kingswells is on SSEN's network. SSEN's FAQ says older properties often have 30A or 60A fuses and that it can upgrade these to an 80A or 100A fuse free of charge. You request that from SSEN yourself. During our survey we read the rating on your cut out and tell you whether to apply before a charger or shower is added.
Who owns what at the meter
- SSEN: the sealed cut out and the main fuse in it.
- Your energy supplier: the meter.
- You: the meter tails, the consumer unit and every circuit beyond it. This is the part we replace.
If SSEN or your supplier has to do something first, we tell you at the survey.
Ask about your supplyNew board, EV charger or rewire in Kingswells?
An EV charger needs a new board only when there is no spare way, the charger circuit cannot be protected properly, or the supply cannot carry the extra load.
Plenty of Kingswells driveways get a charger without touching the main board, sometimes with a small dedicated unit beside it. Where the main board has to change anyway, doing board and charger on one visit costs £750 to £1,000 + VAT and avoids a second shutdown. Our article on a consumer unit upgrade for an EV charger explains how we decide, and the charger itself is covered on our EV charger installation in Kingswells page.
The readings we take before a board change also show the state of the cable. If they point to wiring that is past its best, we say so and quote it separately rather than adding it to the board price. See our page on a rewire in Kingswells for when that is worth doing.
Ask any installer these three
- Does my current board have a free way?
- Which device will protect the new circuit?
- Can my main fuse carry the new load with the house running?
Every written quote we send answers all three.

Consumer unit questions from Kingswells
Something not covered? Call 07304 027013 or send us a message.
What is the average price to replace a consumer unit in Kingswells?
Most Kingswells homes fall between £550 and £950 + VAT with us. A smaller board with fewer circuits sits near £550 + VAT, a large house with many circuits nearer £950 + VAT, and a board fitted alongside an EV charger costs £750 to £1,000 + VAT. Bonding, new meter tails and repairs to a circuit that fails testing are priced separately after the survey.
Can I get a free consumer unit replacement from the government?
We know of no Scottish or UK scheme that funds a consumer unit on its own. The Home Energy Scotland funding page, read on 6 October 2026, covers insulation, heating and heat pumps rather than electrical work. SSEN can upgrade an older 30A or 60A main fuse to 80A or 100A free of charge, but that is SSEN's equipment, not your consumer unit.
How long does a consumer unit replacement take?
One working day for a typical Kingswells house, with the power off for roughly 4 to 6 hours. Missing bonding, new meter tails or moving the board can add time, and you are told that at the survey.
Can I replace my consumer unit myself in Scotland?
Not in a way anyone could rely on. Part P does not apply in Scotland, but the Building (Scotland) Regulations do, including standard 4.5 on electrical safety, and isolating the board usually means removing SSEN's sealed main fuse. Without full testing and an Electrical Installation Certificate there is nothing to show a buyer, insurer or letting agent.
Does a split load or dual RCD board have to be replaced?
No. A dual RCD split load board still complies with BS 7671:2018+A4:2026. We replace one when it has a fault, cannot take a new circuit, or when you would rather a single fault switched off one circuit instead of a whole bank of them.
Does my plastic consumer unit need replacing?
Not because it is plastic. Regulation 421.1.201 requires a non combustible enclosure for a consumer unit being fitted in a home now, but it does not make an existing plastic board a defect. Replacement is worth it when the board lacks RCD protection, shows damage or cannot take what you need.
Do I need a building warrant to replace a consumer unit in Kingswells?
Not for a like for like replacement, which Schedule 3, type 24 of the Building (Scotland) Regulations 2004 lists as work not needing a warrant, provided the result is no worse than before. The work still has to meet the regulations. Kingswells is in Aberdeen City, so Aberdeen City Council is the building standards authority.
My Kingswells rental board has no RCD. What do I need?
Work on the board, usually a replacement. The Repairing Standard guidance asks for one or more 30 mA RCDs in the main consumer unit, normally covering the socket circuits as a minimum. A split load board with the sockets under an RCD generally meets it, and the five yearly EICR is still a separate duty.
Do I need a new consumer unit for an EV charger?
Not always. It depends on a spare way, the right protection for the charger circuit and enough supply for the added load, and a small dedicated unit is sometimes the answer. If the main board has to change too, board and charger together cost £750 to £1,000 + VAT.
Is Kingswells in Aberdeen City or Aberdeenshire?
Aberdeen City. Kingswells has AB15 8 postcodes and sits on the west side of the city, while neighbouring Westhill is in Aberdeenshire. Warrants and landlord registration for a Kingswells address go through Aberdeen City Council.
