Yes. Hadleigh is within our core service area, 48 miles from our Isleham base. We install Fox ESS, SolarEdge, and Tesla Powerwall battery storage systems for homes and businesses across Hadleigh and the surrounding area.

Battery storage in Hadleigh typically costs £2,800–£6,500 installed, depending on capacity. A 5kWh battery costs approximately £2,800–£3,800. A 9.5kWh battery costs £4,000–£5,200. All installations include 0% VAT. When combined with solar panels, the total system cost is eligible for 0% VAT until March 2027.

Yes. We retrofit battery storage to existing solar panel systems across Hadleigh. We first assess your current inverter — if it is a hybrid-ready model (Fox ESS, SolarEdge, Huawei) a battery can be added directly. Older string inverters may require an AC-coupled battery such as the Tesla Powerwall. We assess this during your free survey.

A 9.5kWh battery added to a 4kW solar system in Hadleigh typically saves an additional £300–£600 per year compared to solar alone, by capturing surplus daytime generation for evening and night use. With a smart tariff like Octopus Agile, savings increase further by charging the battery on cheap overnight electricity (typically 2–8p/kWh).

Battery storage is most cost-effective when you already have or plan to install solar panels, have high evening electricity use, or can use a smart tariff. For most Hadleigh homeowners with solar, battery storage reduces grid dependency to under 20%, with payback typically in 7–9 years. Properties with an EV also benefit significantly — battery-charged EV charging can cost as little as 2p/mile.

A battery storage installation typically takes 4–6 hours for a single unit. Combined solar and battery installations take 2–3 days. We can usually schedule Hadleigh installations within 3–5 weeks of survey. Our proximity means we prioritise same-week callouts for Hadleigh customers when availability allows.

The Fox ESS EVO (5–10kWh) is our most-installed battery for Hadleigh homes. It uses modular LiFePO4 chemistry with smart tariff integration and a 10-year warranty. For homes with existing SolarEdge inverters, the SolarEdge Energy Bank is the natural pairing. For backup power priority, Tesla Powerwall 3 leads the market. We recommend the right system based on your existing setup during the free survey.

No. Domestic battery storage systems are permitted development and do not require planning permission. There are no restrictions on battery storage in conservation areas or listed buildings (unlike solar panels, which may require consent for listed buildings). Batteries are typically installed in a garage, utility room, or purpose-built external cabinet.
