Solar Panel Installation in Woking

For a typical Woking home, solar panels usually cost between £5,000 and £9,500. As a guide, 3kW systems start at around £5,000, 4kW systems typically cost £6,500 to £8,000, and 5kW systems £7,500 to £9,500, while larger installations of 6kW or more start at around £9,000. These prices include the 0% VAT rate that currently applies to domestic solar. The exact cost depends on your roof, access and equipment, and we confirm a fixed price after surveying your property.

Many Woking households with a 4kW system save somewhere around £500 to £700 a year, but your own figure will depend on your usage and tariff. The more solar electricity you use directly — running the dishwasher or washing machine during the day, for example — the greater the saving. Pairing panels with a battery, an EV charger or a smart tariff can increase savings further. We base our savings estimate on your actual bills, so the figures you see in our proposal reflect your home rather than a national average.

Usually not. Solar panels fitted to the roof of a house are generally permitted development, as long as they do not project more than 200mm from the roof surface and are positioned to minimise their visual impact where practical. Extra considerations apply if your home is listed or sits in one of Woking’s conservation areas, where panels on walls fronting a road are not permitted development and a more careful design may be needed. Our survey includes a check of your address so you know where you stand before any work is booked.

Woking Borough Council has designated conservation areas including the Basingstoke Canal, Horsell, Old Woking, St Johns, Wheatsheaf, Byfleet Corner, Mount Hermon, Aviary Road in Pyrford, and Old Avenue and Birchwood Road in West Byfleet, among others. You can check using the council’s online mapping, or we will check for you. Being in a conservation area does not rule solar out — roof-mounted panels are often still possible — but it does make siting and appearance more important, so we may recommend a rear roof slope, black panels or an in-roof system.

Not necessarily. The difficulties people hear about mostly relate to older “rent-a-roof” or free solar schemes, where a third party leases the roof space for many years and buyers or mortgage lenders may want the lease reviewed. When you own your system outright, as with every installation we carry out, the panels simply transfer with the house. Keeping your MCS certificate, electrical certificates, warranties and SEG paperwork together makes the process straightforward, and many buyers see lower energy bills as a positive.

Surrey’s councils, including Woking Borough Council, have supported Solar Together Surrey, a group-buying scheme that runs in rounds with set registration windows — the most recent round opened for registrations in summer 2025. Outside those windows, you can still reduce the cost of going solar: domestic installations currently have 0% VAT, and an MCS-certified system allows you to earn Smart Export Guarantee payments. We are happy to give you an independent quote to compare against any group-buying offer. Read our guide to 0% VAT on solar panels.

Quality panels are designed for a long working life. Most carry a manufacturer performance warranty of around 25 years, and systems often keep generating well beyond that, with output reducing only gradually over time. Inverters generally have 10 to 12-year warranties and may need replacing once during the life of the system. Keeping the panels reasonably clean and checking your monitoring from time to time is usually all the maintenance needed. See our solar panel maintenance page for more.

The Smart Export Guarantee (SEG) requires larger energy suppliers to pay you for surplus electricity your panels send to the grid. You choose an SEG tariff — which does not have to be with your current electricity supplier — and are paid per kWh exported, with rates that currently vary widely between suppliers and tariffs. To qualify, your system needs to be MCS certified and have a suitable smart or export meter. We provide the documentation you need to apply. Our SEG guide for 2026 explains the options.

The right size depends on how much electricity you use each year, how much suitable roof space you have, and your plans for the future. As a broad guide, smaller households often suit a 3kW to 4kW system, while larger families, or homes planning an electric car or heat pump, may benefit from 5kW, 6kW or more. We work from your actual consumption during the survey, so your Woking system is sized to your home rather than to a standard package.

Yes. A smart EV charger can be set up to use surplus solar generation, so on bright days your car charges from your own panels. In winter, or when the car is away during daylight, the charger can draw from the grid, ideally on an off-peak EV tariff. Many Woking homeowners install panels, a battery and a charger together so everything is designed to work as one system. Find out more in our guide to solar EV charging.

Solar is a considerable investment, and we can talk you through payment options that may help spread the cost. Get in touch and we will explain the current arrangements available to Woking homeowners, so you can decide what works best for your budget.
