Solar and battery for Faversham homes, priced before you ask.

As of October 2026 we estimate about £5,500 to £7,500 for 4 kWp of solar, and about £8,500 to £12,500 for 4.5 kWp with a 5 kWh battery. A 5 kWh battery fitted to solar you already have is about £2,750 to £4,750. These are our estimates, set against Energy Saving Trust costs, and they are not quotes.

On savings alone a battery usually pays back slowly, often longer than its 10 to 12 year life, unless you can fill it on a cheap overnight tariff or you run an electric car or heat pump. The Energy Saving Trust says savings will not always justify the cost on their own. The estimator shows the sums for your house, and we will tell you if a battery is not worth it.

On 31 March 2027. GOV.UK VAT Notice 708/6 sets the zero rate to that date and the reduced rate of 5% from 1 April 2027, unless the rules change. A battery installed on its own gets the same treatment.

Most house roofs in England are permitted development. In a conservation area, panels must not be fitted to a wall, balcony or roof enclosure that fronts a highway, and listed buildings need consent. Equipment has to be sited, so far as practicable, to minimise its effect on appearance. Swale Borough Council supplies records for around 50 conservation areas, including Faversham Town, Ospringe and Preston-next-Faversham, and its own advice may be stricter, so we check your address first.

Plug-in solar has been legal in Great Britain since 27 August 2026 for approved kits, with written permission from your landlord or freeholder. A battery inside the home is another route, again with permission. Our plug-in solar page sets out the rules and what each option can and cannot do.

UK Power Networks runs the local network, through its South Eastern Power Networks licence area. Your installer notifies them, and larger systems need their approval before work starts. We handle the paperwork and confirm the operator from your meter number.

Under the Smart Export Guarantee every rate must be above zero. On 7 October 2026 supplier pages showed 3p to 18p per kWh: 4.1p for a plain Octopus SEG, 12p at British Gas for its electricity customers, 17.5p at E.ON Next for E.ON-installed systems and 18p at EDF for systems bought from EDF. The Energy Saving Trust says typically about 12p.
