Why homeowners choose Selenium
One qualified electrician, start to finish
Most solar companies send a salesperson, then a stranger with a van. Selenium Energy is family run: Steve surveys your property, prices it honestly and does the installation himself with his own small team. That is why every Google review so far is five stars.

Free survey, quote in 48 hours
A clear written price with the exact panels, inverter and battery listed: usually back with you inside two days of the visit.
0% VAT applied
Often done in a day
Typical domestic solar and battery installs are completed in one day, EV chargers in a few hours, with everything tidied before we leave.
Guaranteed and protected
Two-year workmanship guarantee plus manufacturer warranties up to 30 years, and 0% VAT on solar and battery installations.
What we install
Renewables and electrical work under one roof
Solar, battery and EV charging backed by a working electrician, so the wiring, consumer unit and certification are handled by the same person, not passed to a third party.
Every roof is different, so solar is quoted individually rather than sold off a price list. These are recent systems we installed and what they cost.
£6,995
installed
10 panels · Fox EP6 5.76kWh battery · Fox inverter
A full domestic solar and battery system, installed and commissioned with 0% VAT applied to the quote.
£8,500
installed
13 panels · 2 × Fox 5kW batteries · Fox inverter
A larger array with twin battery storage, so daytime generation is still available in the evening.
£8,900
installed
12 panels · Sigenergy 10kW battery · 5kW inverter
Solar with 10kW of storage and app monitoring, set up to charge when electricity is cheapest.
EV charger installations start from £900 supplied and fitted, or from £500 to fit a charger you have already bought. Solar and battery installations carry 0% VAT.
How it works
Three steps from enquiry to a lower electricity bill
01
Free survey, no salespeople
Steve visits, checks your roof or fuse board, looks at your usage and tells you straight whether the job stacks up.
02
Fixed written quote in 48 hours
A clear price listing the exact equipment, with 0% VAT applied on solar and battery. A 25% deposit secures your date.
03
Installed, tested and certified
Usually a single day on site, then full certification, a walkthrough of your app and a two-year workmanship guarantee.
Winchester is home, and most weeks are spent on roofs and driveways across Hampshire. We also travel to Salisbury, Reading and Oxford for solar, battery and EV charger installations.
Steve is MCS-qualified for solar PV and battery installation and the company's MCS accreditation is currently in progress. We are registered with RECC, the Renewable Energy Consumer Code, and are OZEV-authorised for EV charger installations.
What does a solar and battery system cost?+
Every roof is different, so solar and battery work is quoted individually rather than sold off a price list. Recent installs have ranged from £6,995 for 10 panels with a Fox EP6 battery to £8,900 for 12 panels with a Sigenergy 10kW battery. Solar and battery installations also carry 0% VAT.
How quickly will I get my quote?+
Surveys and quotes are free and are typically with you within 48 hours of the visit. You deal directly with Steve throughout: there are no salespeople and no follow-up pressure.
How long does an installation take?+
Most domestic solar and battery systems are completed in a single day, and a standard EV charger install is usually a few hours. Rewires and larger electrical projects are scheduled around your household.
Am I covered if something goes wrong?+
All workmanship is guaranteed for two years, on top of manufacturer warranties on the equipment supplied: up to 30 years depending on the brand. All electrical work is certified to the 18th Edition BS 7671 wiring regulations under NAPIT and Part P.
How does payment work?+
A 25% deposit secures your installation date, with the balance due on completion once you are happy with the work.
Why Selenium
An independent installer, not a national sales operation
“The person who prices your job is the person who fits it: there is nobody in the middle adding commission to your quote.”

Deposit, balance on completion
Selenium Energy was set up by Steve Higgins after 25 years as an electrician, much of it spent working for larger companies where the sales pitch mattered more than the installation. Going independent means the person who prices your job is the person who fits it, and there is nobody in the middle adding commission to your quote.
That electrical background is what separates a solar install done properly from one that causes problems later. Panels, inverters and batteries are only as good as the wiring, isolation and consumer unit behind them. Because Steve holds City & Guilds 2391 inspection and testing and the 18th Edition qualification, and is NAPIT registered and Part P approved, the whole system is designed, wired and certified by one accountable person: including any board upgrade the installation needs.
The same applies to EV charging. As an OZEV-authorised installer we fit Fox, Zappi, Ohme and Wallbox units, tie them into an existing solar array where it makes sense, and load-test the supply first so your charger is not sharing capacity it does not have. Most home charger installations take a few hours, and pricing starts from £900 supplied and fitted or from £500 to fit a unit you have bought yourself.
Alongside the renewables work we still do everything a household needs from an electrician: consumer unit upgrades, full and partial rewires, EICR safety inspections and certificates for homeowners and landlords, extra sockets and lighting, outdoor and outbuilding supplies, smart home and energy monitoring, and fault finding when something trips and nobody can say why. Emergency call-outs are available outside standard hours, and enquiries can be sent through this site at any time of day.
On money: solar and battery installations carry 0% VAT, a 25% deposit secures the installation date, and the balance is only due once the work is complete and you are happy with it. Workmanship is guaranteed for two years and equipment carries manufacturer warranties of up to 30 years depending on the brand: Fox ESS is the preferred system and Duracell battery installations are also covered. MCS accreditation for solar and battery is currently in progress, and we would rather say that plainly than overstate it.
If you are weighing up solar, a battery retrofit, a home charger or a rewire, the next step is simple: book a free survey. You will get an honest assessment, a written quote within about 48 hours, and no follow-up pressure.
