Solar and battery installers for Surrey and South West London
Solar done once.Done properly.
A family-run installer with over 20 years in electrical work. We design every system from your own bills after an in-person survey, and fix your price in writing.
Book your free survey0% VAT on solar and batteries ends 31 March 2027.
Every price rise lands on your bill. Your roof can do something about it.
A well-designed solar and battery system lets you run your home on power you generate yourself, store it for the evening, and get paid for what you export.
Most homeowners hesitate over two things: the cost, and finding an installer they trust. We built the way we work around both. You get a firm, written price after a proper survey, and the people who design your system are the people who stand behind it.
0% VAT until 31 March 2027. From 1 April 2027 the rate on home solar and batteries is due to rise to 5%.

Your own power, long after sunset.
A battery stores what your panels make during the day, so the oven, the heating and the car run on it at night.

Five promises, in writing.
Solar is a 25-year decision. These go into your contract.
Forecast Promise
If your system produces less than we forecast in its first year, for reasons within our control, we put it right at our cost.
Workmanship warranty
Our workmanship is covered by an insurance-backed warranty, so your cover continues whatever happens to us.
Response Promise
A reply within one working day, from someone who knows your system.
Fixed Price Promise
The price on your signed contract is the price you pay. Nothing is added on installation day.
Tidy Home Promise
Scaffolding down promptly, cables hidden or neatly trunked, and your home left as we found it.
Solar that looks like it belongs on your house.
Your home is probably your biggest asset, so the installation should add to it. We plan the layout as carefully as the output.
- All-black panels with black frames, for a clean, even finish
- Symmetrical layouts planned in the design, never decided on the roof
- Cable runs hidden or neatly trunked, inside and out
- Battery and inverter placed where you want them, agreed at the survey
- Bird-proofing mesh available to protect your roof
A father and son, and twenty years of electrical work.
Electrasol is run by a father and son. One has spent more than 20 years as an electrician and has been fitting solar since 2019. The other makes sure every customer knows what is happening, and when.
We started the company after meeting too many homeowners who had been sold a package over the phone, then left chasing a call centre once the scaffolding came down. We run every job the way we would want our own family's installation handled.
Every installation is signed off by our lead engineer before handover. When you call, you speak to someone who knows your system.
We install across Surrey, South West London and north-west Kent.

Get my exact figuresWhat homeowners ask us
How much does a system cost?
It depends on your roof, your usage and whether you add a battery, which is why we price after the survey. Your price is then fixed in writing in your Home Energy Plan.
Is the survey really free?
Yes. The survey and your written Home Energy Plan are free, and there is no obligation to go ahead.
How long does installation take?
Most homes take one to two days once the scaffolding is up.
Do solar panels work in winter and on cloudy days?
Yes, though they produce less than in summer. Panels generate from daylight, so they still work under cloud. A battery lets you keep more of what you generate for the evening.
Do I need planning permission?
Most houses do not, because roof-mounted solar usually counts as permitted development. Listed buildings, conservation areas and flat roofs can have extra rules. We check this at the survey.
Will I be paid for the power I export?
Yes. Under the Smart Export Guarantee, energy suppliers pay you for electricity you send to the grid. We set up your export tariff as part of every installation.
Do I need a battery?
Not always. If someone is home in the day, solar alone can work well. If your home is empty by day and busy in the evening, a battery usually makes a big difference. Your plan shows both options.
What happens if something goes wrong?
You call your project lead. Our workmanship is covered by an insurance-backed warranty, and your panels, inverter and battery carry their own manufacturer warranties.
Is the 0% VAT rate ending?
Yes. The 0% VAT rate on installing solar panels and batteries in homes runs until 31 March 2027. From 1 April 2027 it is due to rise to 5%.
