A fuse box upgrade in Aberdeenshire from Faithful Spark Electricians costs from £550 + VAT for a typical domestic consumer unit, with a guide of up to £950 + VAT on larger or more involved boards. A surge protection device adds £40 to £80 + VAT, and a new board fitted together with an EV charger circuit is £750 to £1,000 + VAT. Older, rural and TT earthed properties often need checks a town semi does not, such as testing the earth rod or a second board in a garage or steading, so we survey and test before we fix the price.

How much a consumer unit replacement costs in Aberdeenshire
A new consumer unit for a typical Aberdeenshire home costs from £550 + VAT. The figure rises with the number of circuits, the state of the earthing and how many boards the property has. All prices below exclude VAT.
Our prices
| Consumer unit, typical home | from £550 + VAT |
| Bigger or more complex board | up to about £950 + VAT |
| New board with an EV charger circuit | £750 to £1,000 + VAT |

| Extra RCBO, per device plus fitting | £25 to £30 + VAT |
| EICR, main board and first 5 circuits | from £150 + VAT |
What changes the price out here
- The earth rod. On a TT supply we test the electrode before anything else. A corroded clamp or a poor reading means a new rod first.
- More than one board. A garage, workshop or steading fed from the house has its own board and its own cable run to check.
- Circuit count. Every circuit is a device to fit and a set of tests to record.
- Meter tails and bonding. Old tails or missing bonding to water and oil pipes are put right before the board goes on.
- What the testing finds. A circuit that fails is priced separately and shown to you first.

Is it worth upgrading an old fuse box in Aberdeenshire?
Upgrading is worth it when the board gives no protection against earth faults, shows heat damage, or has no room for something you need to add. A board being old is not, on its own, a reason. In the granite cottages, farmhouses and older terraces of the shire, these are the boards we find most.
- Rewireable fuse boards. Fuse wire in pull out carriers to BS 3036, often in a wooden or bakelite box under the stairs or in a porch. Overload protection only, and no RCD anywhere, so nothing guards against current leaking to earth.
- Breaker boards with no RCD. Easier to reset than fuses, with the same gap in earth fault protection.
- Early split load boards. One or two RCDs, each covering a bank of circuits, usually in a plastic case. These are compliant. Their weakness is that one fault on, say, the outside sockets switches off half the house with it.
- Boards that have grown sideways. Rural installations collect add on switches, timers and small boards for a garage, a borehole pump or off peak heating. Each was fine when fitted. Together they can be hard to isolate safely and hard to fault find.
- Full boards. Working, but with no spare way for a shower, an EV charger, a heat pump or a new outbuilding circuit.
Electrical Safety First makes the same point we do: an older board without RCDs is not automatically unsafe, and an inspection is how you find out. If you are unsure, an EICR in Aberdeenshire from £150 + VAT tells you whether the board needs replacing before you spend more. If it does, the board itself is the job we quote.
Upgrading a consumer unit on a TT earthed rural supply
Many rural Aberdeenshire properties fed by an overhead line have no earth from the network. The house earths through its own electrode, a rod in the ground. That is a TT supply, and it changes how the new board is designed and tested.
Because the earth fault path runs through the soil, its resistance is high, and ordinary circuit breakers cannot clear an earth fault quickly enough by themselves. Fault protection on a TT installation therefore depends on RCDs. Our normal design is an RCBO on every circuit, often with a time delayed 100 mA RCD at the front, so a fault on one circuit trips that circuit and the delayed device only acts as a backup. The regulations set the outcome and leave the design to the installer, so we explain ours rather than quote a regulation number for it.
What we test before the old board comes off
- The earth electrode resistance, measured, not assumed
- The rod, its clamp and the earthing conductor back to the main earthing terminal
- Whether the rod is still where the paperwork says, and not buried under a new path or extension
- Main bonding to water, oil and any other incoming metal services
If the rod is corroded, damaged or reads too high, it is replaced or supplemented before the new board is energised. A town house on a network earth has none of this, which is why a like for like price from a city quote rarely fits a farmhouse. Overhead supplies are also more exposed to lightning and switching surges, so on a TT property we normally recommend a surge protection device at £40 to £80 + VAT.
Overhead supply or an earth rod at your property?
Tell us when you call. We plan the electrode test into the survey so the price holds on the day.
Fuse boxes in garages, workshops and steadings
A second board in a garage, workshop or steading is common on Aberdeenshire properties, and it is assessed as part of the same installation as the house. Sometimes only the main board needs replacing. Sometimes the outbuilding board is the urgent one.
The cable run to the outbuilding
The supply cable from the house to a garage or steading is often the oldest part of the job. We check its size, how it is protected along the route and how it is terminated at each end. An undersized or damaged run is replaced before the new board relies on it.
Earthing at the outbuilding
An outbuilding can take its earth from the house or need its own arrangement. That is a design decision we make after testing, not before, and we explain it on the quote.
Damp, dust and livestock
A board in a steading or byre lives a harder life than one in a hall cupboard. Position, enclosure and how cables enter it matter more, and we price for a board that suits the building.
Inspecting every board together
If you want an inspection first, our EICR covers the main board and first 5 circuits from £150 + VAT, and each extra board is £70 + VAT plus £15 + VAT per circuit on it. You then know which board needs work before paying for any.
Adding a room rather than a building? Our page on a consumer unit upgrade for a home extension covers that case.
Why we fit an RCBO on every circuit in rural homes
An RCBO gives each circuit its own overload and earth fault protection, so one fault switches off one circuit and the rest of the property stays live.
On a split load board, a single earth fault on a garden socket or the workshop lights can drop a whole bank of circuits at once. In town that is an inconvenience. On a farm or a remote cottage it can mean the heating, the water pump and the freezers go off together, sometimes while nobody is there to notice.
- A fault in one building does not darken the others
- No shared RCD to nuisance trip a whole bank on a damp morning
- The tripped device tells you where the fault is
- Spare ways planned for the loads you are likely to add next
To be straight about it: an all RCBO board is better practice, not a legal requirement, and a working split load board remains compliant. We recommend RCBOs because of what happens when something goes wrong, not because a rule forces it.
How long a fuse box upgrade takes in Aberdeenshire
Most single board upgrades in an Aberdeenshire home take one working day, and the power is off for a few hours of it rather than the whole day. A property with an outbuilding board, a new earth rod or circuits that need repair takes longer, and we tell you that at the survey. For the hour by hour detail, read how long a consumer unit replacement takes.
- Step 1
Survey and test
Board, earthing and the circuits behind it, so the price is fixed on facts.
- Step 2
Plan the switch off
We agree a window around freezers, borehole pumps, heating and anyone working from home.
- Step 3
Change the board
Isolate, remove the old board, fit the new one and connect each circuit to its own device.
- Step 4
Test everything
Continuity, insulation resistance, polarity, earth fault loop impedance and RCD trip times, circuit by circuit.
- Step 5
Certificate
You receive the Electrical Installation Certificate and a walk through of the new board.
When old wiring will not take a new board
A modern RCD board is far less forgiving than the fuse board it replaces. On older rural installations the testing can turn up a borrowed neutral shared between two circuits, lighting wired without an earth, or rubber insulated cable that leaks to earth. The old fuses never noticed. The new board will trip on them.
Where that happens you see the reading, the options and the price before anything changes. Sometimes it is a small repair. Sometimes part of the property needs rewiring before a new board can be signed off safely. Testing at the survey is how we keep those surprises off the day itself.
Want the board changed in one visit?
We book weekday slots and plan the switch off around your pumps, freezers and heating.
What Amendment 4 means for a new board in Aberdeenshire
Boards are now fitted to BS 7671:2018+A4:2026, which is still the 18th Edition. Quotes and national websites often overstate what it demands. This is what applies to a board in an ordinary Aberdeenshire home.
Metal enclosure for new boards only
Regulation 421.1.201 requires a non combustible enclosure, in practice metal, for a consumer unit fitted in a home today. It does not make your existing plastic board a fault or a reason to replace it.
AFDDs recommended, not required
Arc fault detection devices are required on socket circuits up to 32 A in high rise residential buildings, HMOs, purpose built student accommodation and care homes. In a farmhouse, cottage or family home they are a recommended extra you can choose.
Surge protection: your choice, recorded
The owner of a single home can decline a surge protection device, and that decision is written on the certificate. On an overhead rural supply we usually advise fitting one.
RCBO throughout is good practice
No regulation forces an RCBO on every circuit in a home. A dual RCD split load board is still compliant. On a TT supply the design has to give RCD protection, which is why we use RCBOs there.
Can I replace my consumer unit myself?
We would not advise it, and the result would not be accepted by an insurer, a buyer's solicitor or a letting agent. Safe isolation normally means removing the sealed main fuse, which belongs to SSEN and must not be broken into. The new board then has to be tested circuit by circuit with calibrated instruments and recorded on an Electrical Installation Certificate. In Scotland the building owner is responsible for making sure electrical work meets the building regulations, and BS 7671 is the standard that shows it does.
Building warrants and Aberdeenshire Council
Part P and Building Control notification are England and Wales rules and do not apply here. A like for like board change in a house of up to two storeys does not need a building warrant from Aberdeenshire Council. In flats, maisonettes and buildings of three storeys or more, wider work such as a rewire can need one, and that duty sits with the owner, so we check it at survey. Every board change ends with an Electrical Installation Certificate, which is a different document from an EICR.
Can you sell a house in Aberdeenshire with an old fuse box?
Yes. No Scottish rule requires a new consumer unit before a house goes on the market, and an old board is not automatically a fault.
The Home Report a seller must have is set out in the Housing (Scotland) Act 2006 and its 2008 regulations: a survey report, which includes information on energy efficiency, and a property questionnaire. An electrical test is not one of the prescribed documents. The surveyor looks rather than tests, so if they see an old fuse box they may comment on it and suggest an electrician checks the installation, and buyers' solicitors and lenders often ask about it. Electrical Safety First tells buyers not to rely on the standard survey for electrical safety.
If your sale is coming up, the useful paperwork is an EICR, which shows the real condition, or an Electrical Installation Certificate if you replace the board. We can do either before the Home Report goes out.
Is there a free fuse box replacement in Scotland?
We cannot find any government scheme that pays for a fuse box or consumer unit replacement on its own.
Home Energy Scotland's funding page, checked on 6 October 2026, lists grants and interest free loans for energy saving work such as insulation, heating and heat pumps, Warmer Homes Scotland for eligible households, and a rural uplift for rural and island homes. None of them is a grant for a board by itself. If someone offers a free board through a scheme, ask which scheme, then check it on Home Energy Scotland's funding finder.
How often should a consumer unit be replaced?
There is no fixed replacement age. A board is replaced when it stops protecting properly, is damaged, or cannot take a circuit you need. Inspection is how you find out: every five years for a private let, and Electrical Safety First recommends every ten years for an owner occupied home.
Consumer units in let property across Aberdeenshire
Under the Repairing Standard, the statutory guidance says 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." (Annex D3, paragraph D.55.)
What that means for a rural let or a cottage
- A let with no RCD at all needs work, and usually a new board is the right fix.
- A working split load board whose RCDs cover the sockets generally complies.
- The guidance does not demand RCD protection on every circuit or an all RCBO board.
- The EICR is a separate duty, due every five years.
We fit boards between tenancies and arrange access through your agent, wherever the property is in the shire.
A new consumer unit with an EV charger in Aberdeenshire
A new board fitted together with an EV charger circuit costs £750 to £1,000 + VAT. Doing both in one visit costs less than two separate jobs.
Whether the main board has to change depends on three things: a spare way, the right protection for the charger circuit, and enough supply for the extra demand. On a TT rural supply the earthing needs the same care for the charger as for the board. Sometimes the main board is fine and a small dedicated unit for the charger circuit is the better answer, as in the photo. Our guide to a consumer unit upgrade for an EV charger explains how we decide, and our page on EV charger installation in Aberdeenshire covers the charger itself.
Planning a heat pump as well? Tell us now, so the board is sized once for both rather than upgraded twice.

How much does a fuse box upgrade cost in Aberdeenshire?
Our fuse box upgrades in Aberdeenshire start from £550 + VAT for a typical domestic consumer unit, with a guide of up to £950 + VAT on larger or more involved boards. A surge protection device is £40 to £80 + VAT, and a new board with an EV charger circuit is £750 to £1,000 + VAT. A new earth rod, outbuilding boards and repairs found by testing are priced separately after the survey.
Can I replace my consumer unit myself?
We would not advise it. Safe isolation normally means removing the sealed main fuse, which belongs to SSEN and must not be broken into. The new board must be tested circuit by circuit with calibrated instruments and recorded on an Electrical Installation Certificate, which is what insurers, buyers' solicitors and letting agents ask for. In Scotland the building owner is responsible for making sure electrical work meets the building regulations.
Is there a free fuse box replacement through the government?
We cannot find any government scheme that pays for a fuse box or consumer unit replacement on its own. Home Energy Scotland's funding page, checked on 6 October 2026, lists support for energy saving work such as insulation, heating and heat pumps, with a rural uplift for rural and island homes, but no grant for a board by itself. If a free board is offered, ask which scheme is paying and check it with Home Energy Scotland.
Is it worth upgrading an old fuse box?
It is worth it if the board has rewireable fuses or no RCD at all, shows heat damage, or has no room for a circuit you need. An older board without RCDs is not automatically unsafe, so if you are unsure an EICR from £150 + VAT will tell you whether replacement is needed.
How often should a consumer unit be replaced?
There is no fixed replacement age. A board is replaced when it stops protecting properly, is damaged or cannot take a circuit you need. Inspection is how you find out: every five years for a private let, and Electrical Safety First recommends every ten years for an owner occupied home.
Can you sell a house in Scotland with an old fuse box?
Yes. No Scottish rule requires a new consumer unit before a sale, and an old board is not automatically a fault. The Home Report is a survey report, including energy efficiency information, and a property questionnaire, not an electrical test. The surveyor may comment on an old fuse box and suggest an electrician checks it, so an EICR before you market the house answers that question early.
My property has more than one fuse box. Do they all need upgrading?
Not automatically. A house board plus a board in a garage, workshop or steading is assessed as one installation, and each board is judged on its own condition. Sometimes only the main board needs replacing, sometimes the outbuilding board is the priority. An EICR covers extra boards at £70 + VAT each plus £15 + VAT per circuit on them.
What is TT earthing and why does it change the board upgrade?
A TT property earths through its own rod in the ground rather than an earth from the network, which is common where the supply comes in on overhead lines. Earth fault protection then relies on RCDs, so our normal design is an RCBO on every circuit, often with a time delayed 100 mA RCD at the front. We test the earth rod before the old board comes off and replace it if it is corroded or reads too high.
Do I need surge protection on an overhead rural supply?
For a single home it is your choice, and if you decline it the decision is recorded on the certificate. An overhead rural supply is more exposed to lightning and switching surges than an underground one, so we usually advise fitting a surge protection device, at £40 to £80 + VAT.
Is arc fault protection a legal requirement for my house?
Not for an ordinary home. Arc fault detection devices are required on socket circuits up to 32 A in high rise residential buildings, HMOs, purpose built student accommodation and care homes. In a farmhouse, cottage or family home they are a recommended extra you can choose to add.
How long will the power be off?
Most single board upgrades take one working day, with the power off for a few hours of it rather than the whole day. Properties with outbuilding boards, a new earth rod or circuits that need repair take longer, and we give you a realistic timescale at the survey so freezers, pumps and heating can be planned around it.
Does a board change need a building warrant from Aberdeenshire Council?
Not for a like for like board change in a house of up to two storeys. In flats, maisonettes and buildings of three storeys or more, wider work such as a rewire can need a warrant, and that duty sits with the owner, so we check it at survey. Part P and Building Control notification are England and Wales rules and do not apply in Scotland.
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 extra demand. Sometimes a small dedicated unit for the charger is enough and the main board stays. Where the main board needs replacing too, the board and charger circuit together cost £750 to £1,000 + VAT.
