Consumer Unit Upgrades in Willingham

Fuse board specialist, finished with a CAD circuit diagram of your home

Consumer Unit Upgrades

Consumer unit upgrades are what Peacock Electrical does best. A new board starts from £600 supplied and fitted, fully certified, with individual RCBO protection and surge protection fitted as standard. Every upgrade is finished with a professional CAD circuit diagram of your home, so you always know exactly which circuit controls what. It is a speciality, not just another job.

Your consumer unit is the heart of your home's electrical safety, so it should not be treated as just another job. Fuse board upgrades are what I specialise in, and every one is carried out to the highest standard: fully certified, properly planned, and finished with a professional CAD circuit diagram of your home.

A modern board gives each circuit its own RCBO protection, so a fault on one circuit no longer takes out half the house. Surge protection is now fitted on every replacement to guard your appliances and electronics against spikes on the supply.

The circuit diagram is something you will not get from most electricians. It is a clear computer drawing showing where your lights and sockets are, each labelled with the circuit that isolates it. If something trips, you can see exactly which circuit to check and which sockets are connected, which makes finding a fault far easier.

A typical upgrade starts from £600 supplied and fitted, depending on the size of the board and any remedial work needed. I will explain everything clearly, keep the work tidy, and leave you with a safer, better documented installation.

What Our Customers Say

Very impressed with the high standard of the work completed. When we purchased our home one of the first things we found was a distinct lack of electrical outlets, Sam did a fantastic job installing multiple new sockets around the house along with a new TV aerial point. He left everywhere really clean and tidy, the routing of the new aerial from the living room to the loft is very neatly hidden and professionally finished, and his clear attention to detail and care for our home is really refreshing to see.I would highly recommend and wouldn't hesitate to use your services again. Thank you!

Sam Peacock of Peacock Electricals has been very reliable over three visits to my home (a late 16th century listed cottage with electrical circuits fitted when plugs with circular pins were still in use) to deal with three different electrical problems. He does a good clean job and charges a fair price. He also has a very good set up with a real person taking his messages when he is not available. I will be using him again when needed.

Excellent and efficient service by Sam!Sam is a friendly and extremely efficient electrician. It was easy to set up an appointment and he was able to do the work at a convenient day and time. He wired 2 lounge ceiling lights and fitted the lights very well, no mess afterwards and the job was done within the hour at a very reasonable price. I’d highly recommend peacock electrical, I’ll be using them again in the future.

Sam recently completed a consumer unit upgrade at my home, he was polite and explained everything that needed doing.On the day he was changing the consumer unit I had some doubts on the location I had originally chosen, we discussed all the possibilities then put it in a new location that works much better than the original idea. Having a patient tradesman that understands an extra 10 minutes of downtime will not break the bank is refreshing.I’m looking forward to working with Sam again when I re do my kitchen

Sam has undertaken a few jobs for us and more recently I needed an EV charger installed. He recommended a Zappi over the brand I had been looking at. He visited quickly to quote and he carried out the work in good time. His workmanship was neat and tidy and the cost was as quoted which was reasonable for the job.

Peacock Electrical came to investigate electrical issues by previous contractor and quote work for in the future.Sam spoke me through the issues with bathroom earthing from a previous contractor and how he would rectify moving forward, clearly communicating to me what needed doing and how he would be doing it. During the works he had noticed a dangerous fault, which he immediately made safe and explained to me.During a quote for power to my shed, he explained the different options, timescales and showed me what he had in mind. I didn't feel pressured and he listened to my needs as a customer.From the Professional service I recieved, the immaculate loft/hallway when he left and price I am happy with Peacock.I Will be using Sam again.

I've used Peacock Electrical three times now and he's always done a great job and been very professional. The first piece of work he did was to check my installation of outdoor lights, and then he provided an electrical survey of my new house, and finally installed two modern fuse boxes into my new house. I can only highly recommend using Sam for any electrical work you need.
Jamie Fuller

Sam from Peacock Electrical recently changed my consumer unit in my home and and ran power to the garage and fitted a new consumer unit there too. I am very happy with the work done, Sam is extremely friendly and professional and a pleasure to deal with. The work was completed to a high standard and is very neat. I will not hesitate to contact Sam again when I need more electrical work! Many thanks.

Sam is a really genuine tradesman, he is polite, considerate and very hard working.Sam carried out an EICR inspection of my 4 bedroom home and found safety concerns which he promptly quoted for and once I accepted, he undertook the works and made safe and upgraded circuits as required by building regulations. Sam also carried out a list of electrical jobs that I had equested to do.I have every faith and confidence in Sam and will not hesitate to recommend Peacock Electrical!Thanks again Sam 👍

Frequently Asked Questions

Consumer Units Questions

What areas do you cover?

I am based in Willingham and cover Cambridge and the surrounding villages, including Over, Swavesey, Northstowe, Longstanton, Cottenham, Histon, Cambourne, Bar Hill, Waterbeach and Ely. If you are not sure whether you are in my area, give me a call on 07500 500506 and I will let you know.

Are you a qualified, registered electrician?

Yes. Peacock Electrical is NAPIT registered, so all of my work is carried out and certified to current wiring regulations. You get proper documentation with every job, and consumer unit upgrades also come with a CAD circuit diagram of your home.

Who actually does the work?

The electrical work is carried out by me, Sam Peacock. I keep things hands-on and personal so the standard stays consistent on every job, rather than passing you around between subcontractors.

Do you do other electrical work besides EV chargers and consumer units?

Yes. EV charger installations and consumer unit upgrades are my specialities, but I also handle smoke alarms, additional sockets and lighting, fault finding, inspections and full rewires. If you have an electrical job in mind, give me a call and I will talk you through it.

Will you keep the work tidy?

Always. I understand that while I am working it is still your home and not a worksite, and I treat it that way. There is sometimes unavoidable disruption when channelling wires or isolating the supply, but I keep it to a minimum and you will not need to clean up after me.

How do I get a quote?

Just call or message me on 07500 500506, or fill in the enquiry form on this site with a short description of the work. I will get back to you within one working day to talk it through and arrange a look if needed.

How much does a home EV charger cost to install?

A home EV charger starts from £1,000 supplied and fitted. The exact price depends on the charger you choose and how far it needs to run from your consumer unit. I will give you a clear quote before any work starts.

Which EV charger do you recommend?

There are several good options and the right one depends on your car, your home and how you want to use it. I am happy to talk you through the choices, including smart chargers that let you charge on cheaper overnight tariffs, and recommend one that suits you rather than one that suits me.

How is the EV charger connected?

Wherever possible we connect the charger back to your existing consumer unit, which keeps everything neat and in one place. That is our preferred approach. If it is not practical for your setup, we may fit a small additional consumer unit for the charger instead, though that is not our first choice. Either way it goes on its own correctly protected circuit, not spurred off existing wiring.

Will my electrics cope with a charger?

Most homes are fine, but it depends on your existing supply and how much spare capacity you have. I check this as part of the job and will tell you honestly if anything needs upgrading first. Where needed, load management can also let a charger run safely alongside the rest of your home.

Do I get certification for the installation?

Yes. Every EV charger installation is fully tested and certified on completion, and I will talk you through how the charger works before I leave.

How much is a new consumer unit?

A consumer unit or fuse board upgrade starts from £600 supplied and fitted. The price depends on the size of the board and whether any remedial work is needed once the old unit comes off. I will confirm a clear price after taking a look.

Do I actually need my fuse board upgrading?

Sometimes yes and sometimes no, and I will always be honest about it. Older boards without RCD or RCBO protection are worth upgrading for safety, and an upgrade is often recommended alongside other work such as a rewire or an EV charger. If yours is fine as it is, I will tell you.

What is the CAD circuit diagram you provide?

It is a clear computer drawing of your home showing where your lights and sockets are, each labelled with the circuit that isolates it. If a circuit trips you can see exactly which one to check and what is connected to it, which makes finding a fault far easier. Most electricians do not provide this, but I include it with consumer unit upgrades.

What is the difference between an RCD and RCBO board?

On a modern RCBO board every circuit has its own protection, so a fault on one circuit only trips that circuit rather than taking out half the house. It is safer and far more convenient than older split-load boards, and it is what I fit as standard.

Do you fit surge protection?

Yes, on every consumer unit replacement. Surge protection is now a requirement rather than an optional extra, and it guards your appliances and electronics against spikes on the supply.
