How Much Does an Electrician Cost in Plymouth

Published August 2026 | How much does an electrician cost in the UK

A homeowner in Plymouth noticed something unsettling one Tuesday evening in late winter. Every time she ran the kettle while the microwave was going, the kitchen lights flickered before the entire ground floor circuit tripped. She reset the consumer unit three times in a single week before she finally picked up the phone to call an electrician. What started as an irritating inconvenience turned into a proper electrical overhaul and a solid lesson in what professional electrical work actually costs.

What Was Actually Going On

The property was a 1970s semi-detached in Plymstock, one of those parts of Plymouth with a significant amount of pre-1980s housing stock. When our engineer arrived, the problem became clear almost immediately. The consumer unit was original to the house, fitted with old rewirable fuses rather than modern circuit breakers, and it had long since reached the end of its useful life. Rewirable fuse boards were standard in UK homes built before the late 1980s. They work up to a point, but they have real limitations. The fuse wire degrades over time, the contacts corrode, and critically they offer nowhere near the level of protection that a modern unit with residual current devices (RCDs) provides. An RCD cuts power within milliseconds if it detects a fault, protecting both the building and anyone inside it. The old ceramic fuse board had none of that. The trips she had been experiencing were actually the fuse wire doing its job, blowing to protect the circuit when the load exceeded its capacity. The kitchen had been on a single 6-amp circuit since the house was built, and modern kitchen appliances draw far more current than anything that circuit was designed for in 1973. A standard kettle pulls around 3,000 watts. Add a microwave, a fridge running its defrost cycle, and a toaster going simultaneously and you have a recipe for a blown fuse every time. Using the Voltrade GoFIX diagnostic process, our engineer also identified that two existing circuits showed signs of insulation deterioration. This was not visible to the naked eye and was not something the homeowner could have spotted herself. It improved the job from a like-for-like fuse board swap to a more comprehensive piece of work, and it was important to flag before quoting rather than partway through. The core diagnosis: an outdated 1970s consumer unit with rewirable fuses, an undersized kitchen circuit, and deteriorated cable insulation on two existing ring mains.

How the Problem Was Resolved

The job was planned over two days. Day one covered removal of the old consumer unit, temporary isolation of all circuits, and a thorough inspection of the cabling throughout the property. Our engineer was registered with NICEIC, the competent persons scheme covering electrical work in England and Wales. Any electrician carrying out notifiable electrical work needs to be registered with an approved scheme, whether that is NICEIC, NAPIT, or ELECSA, so they can self-certify the completed work and issue the relevant Building Regulations certificate. The old board was replaced with a modern dual-RCD consumer unit, with circuits reorganised so the kitchen had its own dedicated 32-amp ring main rather than sharing a circuit with the living room. The two circuits with deteriorated insulation were re-run using modern twin-and-earth cable where accessible, with the work neatly channelled back into the existing plasterwork. Day two covered testing, final certification, and a full walkthrough with the homeowner. By the end she understood exactly what had been replaced, why it had been replaced, and what the new installation gave her in terms of protection that the old one never provided. All work was notified to Plymouth City Council's building control department through the electrician's competent persons scheme. This is a detail many homeowners miss. When a registered electrician completes notifiable electrical work, they handle the local authority notification themselves. If you use someone who is not registered with an approved scheme and they do notifiable work without the proper certification, you will face real difficulties when you come to sell or remortgage the property.

What This Cost and How Long It Took

The total invoice came to £820, covering parts and labour across two days. For the scope of what was done, that represents reasonable value. Here is how it broke down. Parts:

Dual-RCD 18-way consumer unit: approximately £180
Cable for two circuit re-runs: approximately £90
Sundries including connectors, fixings, and conduit: approximately £40

Labour:

Day one, isolation, removal, and installation: 6 hours at £55 per hour = £330
Day two, testing, certification, and EICR: 4 hours at £55 per hour = £220

The EICR was included as part of the overall job at no additional charge, which is worth noting given that a standalone EICR for a three-bedroom house typically costs between £150 and £280 depending on the number of circuits and condition of the existing installation. For broader context, here are typical costs for common electrical jobs across Plymouth and Devon:

Consumer unit replacement, like-for-like: typically £400 to £700
Consumer unit replacement with additional circuit work or remedial wiring: typically £650 to £1,100
Additional double socket, surface-mounted: typically £80 to £130
Additional double socket, flush-fitted with plasterwork: typically £130 to £200
EICR for a three-bedroom house: typically £150 to £280
Full house rewire, three-bedroom property: typically £4,000 to £7,500, depending on accessibility and whether the property is occupied during the work
Call-out fee: typically £50 to £80, often absorbed into the first hour of labour
Hourly rate for a qualified electrician: typically £45 to £70 per hour

Rates in Plymouth generally sit in the middle of the national range. You will not pay London rates in Devon, but you also will not find the rates typical of some rural areas further north. Demand for consumer unit replacements and rewires is consistent across the city given the age of much of the housing stock, which keeps local electricians busy throughout the year. The job took just under two days as planned. Had the cable deterioration been more widespread, it could have run into a third day. This is exactly why it matters to have an electrician carry out a proper inspection before giving you a price, rather than quoting over the phone without having seen the installation.

How to Spot the Same Issue in Your Home

Not every electrical problem announces itself with repeated trips. Some warning signs are subtler, and catching them early can save you money and reduce risk. Things to check in your consumer unit and around the home:

Old-style ceramic fuse holders rather than modern circuit breakers. If you can pull out a small cylinder of ceramic with a length of fuse wire running through it, the board is due for replacement. These are found in a large proportion of homes built before the late 1980s.
Circuits tripping regularly without an obvious cause. An occasional trip after a clear overload is normal. Repeated trips with no apparent reason point to a fault on the circuit, a failing RCD, or a board that is struggling to handle the load being put through it.
A faint smell of burning or hot plastic near the consumer unit, near a particular socket, or at a light switch. Switch off the relevant circuit and call an electrician. Do not ignore this.
Lights dimming when you run high-draw appliances, particularly in older parts of the house or on circuits that have not been updated in decades.
Sockets or switches that feel warm to the touch, or that show any sign of discolouration or scorching around the face plate.
You are planning significant building work. A kitchen renovation, loft conversion, or rear extension will require electrical inspection and almost always means the existing board will need upgrading to handle the additional load.

If your home is more than 25 years old and has not had an EICR, that is the first thing to arrange. It gives you a formal assessment of the installation's condition with every issue graded by urgency. For landlords renting out property in England, an EICR is not optional. It is a legal requirement every five years, and the certificate must be provided to tenants.

Lessons: What Every Plymouth Homeowner Should Know

The homeowner in this case had been putting off calling an electrician for months. She was not sure what it would cost and was worried about being quoted for work she did not need. Both concerns are reasonable and worth addressing directly. On getting a clear quote: a reputable electrician will give you a written breakdown separating parts and labour. If someone gives you a single lump sum with no explanation of how they've arrived at it, and resists questions when you ask, that is worth paying attention to. You are entitled to understand what you are paying for before you agree to anything. On checking credentials: always verify that your electrician is registered with a competent persons scheme before work starts. NICEIC, NAPIT, and ELECSA all have searchable registers on their websites. For notifiable electrical work, registration is what gives the electrician the legal authority to self-certify. Without it, you may end up with work that cannot be properly certified, which creates genuine problems at the point of sale. On Devon's housing stock: a significant proportion of homes in Plymouth were built between the 1950s and 1980s, and a great many have never had a full rewire. If your property falls into that category, getting an EICR before planning any substantial work is a sensible first step. It tells you exactly what you are dealing with before any contractor starts quoting. On getting more than one price: for a job like a consumer unit replacement, two or three quotes is a reasonable approach. Where you see a significant difference in price, it almost always reflects a difference in scope. Make sure you are comparing like for like rather than simply choosing the lowest number. On timing: the homeowner in this case saved nothing by waiting. The problem was present and getting worse. Had a circuit failed completely or developed a more serious fault in the meantime, the bill would likely have been higher and the risk greater. Electrical faults in older properties do not resolve themselves. Six months after the work was completed, she has had no trips and no flickering lights, and she has her Building Regulations certificate and EICR stored safely for when the time comes to sell. That is what a properly completed electrical job looks like.

Related Questions

Do I need to be home while an electrician replaces my consumer unit?

Yes, it is sensible to be home or to have a responsible adult present throughout the job. The electrician will need to isolate the power supply to the whole property at the start of the work, which means no electricity to anything in the house for the duration. You will also need to be available at the end for a walkthrough before you sign off and receive your certification paperwork. For a job of this scale, being present throughout is practical as well as a good idea.

How long does a consumer unit replacement take in a typical home?

For a three-bedroom property with a reasonably modern wiring layout, a like-for-like consumer unit replacement typically takes between four and seven hours. If the job includes additional circuit work, fault-finding on older wiring, or remedial work identified during the initial inspection, it can extend to a full day or run into a second day. Our engineers always aim to give a realistic estimate rather than a best-case one, so building in a full day is a sensible default for most homeowners.

Is a consumer unit replacement covered by Building Regulations in England?

Yes. Consumer unit replacements fall under Part P of the Building Regulations, which covers electrical safety in dwellings. If your electrician is registered with a competent persons scheme such as NICEIC, NAPIT, or ELECSA, they can self-certify the work and notify your local authority's building control on your behalf. You will receive an Electrical Installation Certificate as proof the work is compliant. If your electrician is not registered with an approved scheme, the work will need a separate building control inspection, which adds cost and delay to the process.

What is the difference between an EICR and an Electrical Installation Certificate?

An EICR (Electrical Installation Condition Report) is a periodic inspection of an existing electrical installation, assessing its condition and identifying anything that needs attention. An Electrical Installation Certificate is issued when new electrical work is completed, confirming the installation meets current standards. When your consumer unit is replaced or your home is rewired, you receive an Electrical Installation Certificate. If you want an independent assessment of your existing wiring, you need an EICR. Both documents should be kept safely and made available to buyers or their solicitors when you sell the property.
