NICEIC electrical services across Somerset

Consumer-unit changes, fuse-board upgrades, rewires and small-commercial fit-outs

Electrical work, properly certified

Renewables grew out of our electrical roots, and we still take on day-to-day electrical work for the homes and businesses we serve. Consumer-unit changes, fuse-board upgrades, partial rewires, kitchen and bathroom circuits, garden offices, and small-commercial fit-outs all sit comfortably in our range.

Every job is signed off under Part P with NICEIC notification, which means you get the building-control paperwork without having to chase your council yourself. If we need to coordinate with the DNO for a supply upgrade or a metering change, we handle that too.

We turn up when we say, work tidy, and explain options before we make changes. If your job overlaps with a planned solar or EV install, we will quote it as one piece of work so the wiring lands in the right place first time, and you do not pay twice for cable runs.

Public liability cover is £5 million, every electrician on the team is qualified and registered, and you get the same point of contact through Chris from quote to sign-off.

Chris from Totum Renuables was recommended to me by my roofer Roof Care 365, they worked together to install a new slate roof and a 6 panel integrated solar system with a 5kw battery. Chris came round and explained everything very clearly and we were ready to go. Installation of the solar system was seamless and Chis keep in constant contact throughout. We are over the moon with the end result and are already reaping the benefits of our investment, being 89% self sufficient after just 17 days! A big thank you to Chris and the team from Totum for making our solar journey a enjoyable experience

We had Totum Renewables install our EV charger, after seeing their workmanship we are now considering having solar & battery storage after discussing our options as Chris made solar seem easy with his in depth knowledge.

I would like to say a big thank you to Totum Renewables and its owner Chris Williams for what has been a fantastic first experience into all things solar and batteries.I started down the Octopus route which limited our installation due to their self imposed rules which didn't work for us. Totum Renewables designed a system for our needs and managed to install the panels where we wanted. Even when we decided we wanted a gateway halfway through the install he sorted this in a few days without issue.Now have 20 Aiko 510 panels fitted along with an Sig Energy gateway (sorry Chris), 4x10kw batteries and an 8kw inverter. They sorted the G99 request in days and ensured a very detailed handover.A professional and very transparent service from Chris throughout, and the fitting was done with a lot of care and attention to detail. We couldn't recommend him highly enough and if you live in the South West he is definitely worth a call.All we need is sun now!Thanks Chris.

Rang for a quote and Chris was incredibly helpful from the start, especially as we were novices and the initial enquiry was the start of us collecting information about solar panels and whether they would work on the roof of our Georgian house. Not pushy at all, answering all questions honestly and explaining everything in easy to understand language. We felt fully informed. For the full site survey a drone was sent up to the roof to take photos, questions asked about energy usage etc. Our bespoke quote came with a full breakdown of costs, when we would be expected to pay back the initial costs and a video explaining the installation process.Would certainly recommend Totum Renewables for their customer service. Thank you Chris.

Having solar is a game changer even on dull days already making such a difference to electricity spend. Chris and team were professional from the outset. From planning to scaffolding to install. All really clean and smooth would not hesitate in recommending them. We also got a power supply from our solar battery in case power failure as have marine fish. Great outcome cannot wait till the sunnier days but also cloudy days the system still generates. I also previously had an EV charger installed by Chris and that’s great too. I drive now for so much less cost. I love solar and EVs thanks Chris and team. Good job ☺️

Chris came to do a full site survey, and out of the 3 solar companies that came out, he was the only one who said he thought I needed a new roof. We have parked the project till next year when the weather is better. But would highly recommend Chris and Totum.

“Chris and the team at Totum were brilliant from start to finish. I first got in touch about an EV charger, but when Chris came to do the survey he explained the benefits of adding solar too. I’m absolutely over the moon with the results. The whole process was clear and straightforward, and the installation was booked and completed the following week. I’m now expecting to save over £1,000 a year on my energy bills and couldn’t be happier with the service or the outcome.”

We first used Chris and his team for an EV charger install and were really impressed with the work. When my energy bills went up, I spoke with Chris and he came out to do a full site survey, explaining the whole process clearly. The installation team were in and out in a day, very neat, polite, and tidy. The system has been saving us money from day one. Really impressive service and I’d highly recommend Totum Renewables.

Totum Renewables were recommended to me by a friend and I’m so glad I got in touch. Chris came around to do the survey and explained everything really clearly, which gave me a lot of confidence in the process. The installation itself was seamless and handled really professionally. The system has been working brilliantly and the savings so far have been great. I’d happily recommend Totum to anyone thinking about going solar.

We had the best experience with Totum renewables. From the time Chris Williams came to our house to do the survey to his last visit to set us up on the various Octopus tarriffs we have been so impressed. He kept us up dated daily with when the scaffolding was coming, panels delivered etc.When Chris and his team came on the day of the installation they arrived really early and didn't stop until the installation was done. They were all very polite and insisted on taking their shoes off when inside the house! Cleared up at the end of the day and left our drive cleaner than when they arrived!!We would highly recommend Chris for solar and EV installations.

Chris came out to review our property for a solar and an ev charge point to see what was the best way to get it done.We went through with the installation and we couldn’t be happier. The money we are saving is better than expected and his team couldn’t have worked harder to get the job done.I can’t recommend this company highly enough.Thank you so much, just wish we came to you sooner!

Chris from Totum Renewables provided me a fantastic service from designing our solar system to installing it which was carried out to a high standard. Chris was very knowledgeable and provided us with all there information we required which made the whole process easy. Since we've had our system installed a few months ago we've received a better performance than initially expected which has been great.

Chris and the team at Totum Renewables did a great job installing solar at my property. Chris came out personally to do the survey, which was really helpful as I had lots of questions. He took the time to explain everything clearly and designed a bespoke system tailored to the layout and needs of the house. The installation was smooth, and we’ve already started seeing significant savings on our energy bills.He’s now due to survey my parents' house too. They’ve got high usage, so I know he’ll tailor a cracking solution for them as well.

Frequently Asked Questions

Electrical Questions

What areas do you cover? ▼

We cover Somerset and the wider South West, including Taunton, Yeovil, Bridgwater, Wellington, Tiverton, Minehead, Highbridge, and Weston-super-Mare. If you are unsure whether you are in our regular catchment, call 01823 212 770 or message us on WhatsApp and we will confirm before booking a survey.

Are you MCS certified and NICEIC registered? ▼

Yes. Totum Renewables is MCS certified for solar PV and battery storage installs, NICEIC approved for general electrical work, a RECC code member for consumer protection, and TrustMark Government Endorsed Quality registered. We carry £5 million of public liability insurance, and our certificates are available on request.

Do you offer free quotes? ▼

Yes. We provide a free, no-obligation site survey for solar, battery, EV chargers and electrical work. The survey takes about an hour, we look at your roof, consumer unit, usage data where available, and we follow up with a written quote that itemises the work clearly. You are not committed to anything until you sign.

Do you offer finance? ▼

Yes. Totum Renewables is an Introducer Appointed Representative of Phoenix Financial Consultants Limited (Financial Services Register No. 1036089), and we can arrange finance options through them for customers who would rather spread the cost of a renewables install. We will explain the options at survey if it is something you would like to consider.

What payment methods do you accept? ▼

We accept bank transfer and major card payments. Payment terms are typically in line with MCS guidelines, with a 25% deposit taken on order, protected under deposit protection. A further stage payment is usually taken on material delivery, with the remaining balance due on completion of the installation. All payment schedules will be agreed with you in writing before work begins.

How long have you been trading? ▼

Chris founded the business after returning from several years working on major construction and renewables projects in Australia, and the move to a renewables-focused offer happened as battery technology started to make domestic installs genuinely worthwhile. The team has worked across solar, battery, EV, and electrical for several years now, and the operating company Electric Plus Ltd is registered at Companies House under number 11967489.

How much does a solar install cost? ▼

A typical Somerset domestic install lands between £7,000 and £24,000, depending on system size, panel choice, inverter, and whether storage is included. We give a fixed written quote after a free survey so you know the price before committing, and finance is available through our Phoenix Financial relationship if you would prefer to spread the cost.

How long does a solar install take? ▼

A straightforward 4 kW to 6 kW domestic rooftop install usually takes one to two days for a small in-house team. Larger systems with storage or commercial arrays take a little longer, and scaffolding sometimes adds a day either side. We give you a clear timeline as part of the written quote so you can plan around it.

What panels and inverters do you use? ▼

We work with Tier-1 panel manufacturers and proven inverter brands including Solis, Growatt, SolaX, and Sigenergy. We do not push a single brand because every roof and every household uses power differently. We will recommend the panel and inverter combination that suits your roof, your usage, and your budget.

Will solar panels really save me money? ▼

On a properly designed system, yes. The exact saving depends on your roof orientation, your daytime usage, and whether you add storage or an EV. We model the realistic payback based on a year of your actual half-hourly usage where we can pull it, and we are upfront if a system would not pay back inside its 25-year warranty.

Do you handle the DNO and MCS paperwork? ▼

Yes. Every install includes the local DNO notification, MCS certificate, and the relevant building-control documentation. You receive the paperwork pack on handover, and we are happy to send digital copies to your conveyancer or insurer if needed.

Can you retrofit a battery to an existing solar system? ▼

Yes. We retrofit AC and DC-coupled batteries onto existing arrays, and we work with Sigenergy, Livoltek, Growatt, and SolaX. We start with a survey of your inverter, consumer unit, and usage data so the storage is sized for the real saving rather than a manufacturer recommendation.

What size battery do I need? ▼

It depends on when you actually use power. We pull your half-hourly usage where the supplier allows, look at evening and overnight consumption, and size the battery to capture the meaningful share of that load without oversizing. A typical Somerset family home is usually well served by 10 kWh of usable storage.

Can I use my battery with Octopus Go or Cosy? ▼

Yes. Time-of-use tariffs work very well with battery storage. We set up off-peak charging windows during the install and link the system to the right monitoring app, so the battery loads up overnight at the cheap rate and discharges through the day. Most battery customers see meaningful bill reductions in the first quarter.

What warranty comes with a battery system? ▼

Most battery systems come with a standard 10 year manufacturer warranty. However, we also offer selected products with 12 and 15 year warranties, which are considered market leading within the industry. Some of these extended warranties are included by the manufacturer as standard, depending on the brand and product chosen.

How much does an EV charger install cost? ▼

A standard 7 kW home charger install lands around £900 to £1,800 depending on cable run, consumer-unit headroom, and earthing requirements. We quote in writing after a quick site survey so the price is fixed before install day, with no surprises.

Which EV charger brands do you fit? ▼

We work with the major brands including QUBEV, Hypervolt, Ohme, EO, and Wallbox. We will recommend the unit that fits your charging pattern, your phone, and your budget, and we will explain the OCPP-compatibility and solar-aware options if those matter to you.

Can I qualify for the OZEV grant? ▼

OZEV grants are still available for some property types, particularly flats and rental properties. We check eligibility at survey and administer the application on your behalf where you qualify. Single-occupancy houses are no longer eligible under current rules, but we will tell you that upfront.

Can I add an EV charger to a solar system later? ▼

Absolutely, and we make it easier when we install the original solar. If you mention an EV is on the horizon at survey, we leave the wiring and consumer-unit headroom in place so the future charger install is faster and cheaper when you are ready.

Should I service my solar system every year? ▼

Yes. An annual check picks up performance drift, isolator faults, and inverter firmware updates before they cost you generation. Our service visit covers DC and AC tests, monitoring health, and a written report. Most customers add it to a once-a-year diary entry alongside their other annual home checks.

What is an EICR and when do I need one? ▼

An Electrical Installation Condition Report is a full inspection of the fixed wiring in a property. Landlords need one every five years by law, businesses commonly need one for insurance, and homeowners often want one before a sale or after major works. We carry out and certify EICRs across Somerset and the South West.

Do you service systems you did not originally install? ▼

Yes. We service solar, battery, and EV charger systems regardless of who installed them. We start with a baseline check, document what we find, and quote any remedial work clearly before proceeding. We are happy to take over annual servicing for portfolios as well as individual properties.

What electrical work do you cover? ▼

All standard domestic and light commercial work: fuse-board (consumer unit) upgrades, full and partial rewires, additional sockets and lighting circuits, fault-finding, EV-charger feeds and isolators, and any electrical work that ties into a solar or battery install. If it's safer to send a separate sparky for a small job we'll tell you straight.

How much does an EICR cost? ▼

Electrical Installation Condition Reports start from £180 for a typical 3-bed semi and go up to £400 for larger or older properties. Price reflects the number of circuits and how accessible the consumer unit is. We provide the formal certificate, a clear remedial list (categorised C1/C2/C3/FI), and an honest quote for any work needed.

Do I need to upgrade my consumer unit before adding solar or an EV charger? ▼

Often, yes. A modern install needs spare ways, RCD protection on the relevant circuits, and adequate main fuse/incoming capacity. We assess your existing board on the survey and only recommend an upgrade if the install genuinely requires it. A consumer unit replacement typically runs £550–£950 fitted.

Are you NICEIC and Part P registered? ▼

Yes. Totum Renewables is an NICEIC Approved Contractor for both general electrical work and solar installations, and we're registered for Part P notification on domestic electrical work. Every job is signed off, documented, and uploaded to Building Control where required, so your property's certification stays clean.

Do you take on commercial electrical work? ▼

Yes, Totum Renewables can assist with both domestic and commercial electrical installations. We are always honest about the type and scale of work we take on, and if we feel a project is outside our scope, we will happily recommend a trusted specialist contractor better suited to the job.
