Consumer unit replacement in Crimond
Replacing a consumer unit in Crimond, from rewireable fuse boards and first-generation plastic units through to modern metal-enclosure RCBO boards. Fixed price agreed in writing before we start, full certification on completion.
8 miles from Fraserburgh via the A90, typically 12 to 18 minutes. Village addresses carry no surcharge on larger jobs. Genuinely rural addresses outside the village, and small single-visit jobs, add £25 to £40 for round-trip travel, always declared at quote stage.
In Crimond specifically
What Crimond property means for this job
On TT-earthed rural property the board replacement includes testing the earth electrode, and where its resistance is too high the electrode itself needs improving before a modern board can protect the installation as intended.
The straight answer
Consumer unit replacement, and when you actually need it
A consumer unit, still widely called a fuse box, is the point where your electricity supply is split into the circuits that feed your house, and where each of those circuits is protected. Replacing it means removing the existing board and installing a new one with modern protective devices, then testing and certifying the whole installation.
The reason most replacements happen is protection rather than age. Older boards, whether rewireable fuses or early MCB units, generally have no residual current device, and RCD protection is what disconnects a circuit fast enough to prevent a fatal shock when someone cuts through a cable or a faulty appliance puts voltage where it should not be. Without it, socket circuits will normally be coded as potentially dangerous on an Electrical Installation Condition Report, which is what makes a report unsatisfactory.
Since 2015, consumer units in domestic premises have been required to be enclosed in non-combustible material, in practice a steel enclosure. A plastic board fitted before that change is not automatically unsafe, but it is one of the factors assessed, and it is why virtually every replacement we fit is a metal-enclosure unit.
Worth checking
Signs this applies to your Crimond property
Rewireable fuses
A board with actual fuse wire predates modern protection entirely. It is not illegal and can still be serviceable, but it cannot provide RCD protection.
No RCD anywhere
A plastic board with MCBs but no RCD is the most common configuration we replace. Socket circuits without 30mA RCD protection are normally coded C2 on an EICR.
Repeated tripping with no cause found
Frequent tripping usually means a genuine fault somewhere in the installation. A new board will not fix the cause, so we find the fault first rather than selling you a board that does not solve it.
An unsatisfactory EICR
Where a report flags the board or the absence of RCD protection, replacement is the direct remedy and the report tells you exactly what needs to change.
How it runs
What happens, step by step
- 1
Survey and quote
We inspect the existing board, the incoming supply arrangement, the earthing and bonding, and the meter tails, then confirm the circuit count. You get a fixed written price inside 24 hours. If the earthing or bonding needs upgrading to make a new board work as intended, it is in that quote rather than appearing later.
- 2
Isolation and safe shutdown
Power is off for the working day, typically four to six hours for a straightforward domestic replacement. We agree the day in advance so you can plan around freezers, home working and heating.
- 3
Installation
The old board is removed, the new enclosure fitted, and every circuit reconnected and identified. Where tails, the main earthing conductor or the main protective bonding are inadequate, those are brought up to standard as part of the job.
- 4
Test and certify
The full installation is tested, continuity, insulation resistance, earth fault loop impedance, RCD operation, and you receive an Electrical Installation Certificate. The board is properly labelled so the next person can see what feeds what.
Common questions
Consumer unit replacement questions
How long does a consumer unit replacement take?
For a straightforward domestic property, typically four to six hours, and the power is off for most of that. Where the earthing and bonding also need upgrading, or where circuits need investigating because they are unidentified, it can run to a full day. We tell you which of those applies after the survey rather than on the morning of the job.
Do I legally have to replace my old fuse box?
No. There is no law requiring you to replace a consumer unit, and age alone is not a reason. What creates a practical obligation is letting the property, because a private rented property in Scotland needs a satisfactory EICR every five years under the Repairing Standard, and an installation with no RCD protection on socket circuits will normally fail that. If you own and live in the property, it is a safety decision rather than a legal one, and we will give you a straight assessment rather than a scare story.
RCBOs or a dual-RCD board?
A dual-RCD board is cheaper and groups circuits behind two RCDs, so one earth fault takes out roughly half the house. An RCBO board gives every circuit its own combined overcurrent and earth leakage protection, so a fault isolates to that circuit alone. If losing a freezer, heating or a water pump while nobody is home would matter to you, RCBOs are worth the difference. If not, a dual-RCD board is a perfectly compliant answer. We will quote both if you want to compare.
Will you need to rewire the house as well?
Usually not, and we will tell you honestly if the answer is yes. Replacing the board does not replace the cable behind it. If the existing wiring is sound, a new board works fine on it. If the wiring is at genuine end of life, rubber insulation, damaged cable, or circuits so heavily extended they are unsafe, fitting a new board on top would be putting good protection on bad cable, and we would rather tell you that up front than take the smaller job.
What certification do I get?
An Electrical Installation Certificate covering the work, with the full schedule of test results. That is the document a solicitor, a letting agent, an insurer or a subsequent EICR inspector will want to see, so keep it with the property paperwork.
