Puredrive Energy

British-designed home battery storage behind the Duracell Energy range

Puredrive Energy is a British company that designs, engineers and manufactures home energy storage systems and EV chargers. Its stated aim is to give households more control over how their homes are powered, so they rely less on the grid and are less exposed to price spikes and peak-time rates. The company describes its teams as UK-based, covering everything from product design to customer support for both homeowners and installers.

Since 2022 Puredrive has held a licence to manufacture and sell Duracell Energy battery storage systems across the UK and key European territories. According to the company, it was selected for the partnership on the strength of its engineering and manufacturing standards. Its current generation of products is brought to market exclusively under the Duracell Energy brand, while Puredrive continues to support customers who bought under the Puredrive Energy name.

The Dura series: single-phase systems for UK homes

The catalogue presented on the site centres on the Duracell Energy "Dura" series, aimed at typical UK single-phase households. The published specifications list a ten-year warranty across the range and a choice of power outputs of 3.6 kW, 4.6 kW, 5 kW and 6 kW, with maximum solar capacity of 10 kWp and an MPPT voltage range of 70 V to 540 V. The units can work either as hybrid or AC-coupled systems, support up to nine units in parallel, and are wall-mounted. A tariff intelligence function is described as automating more than 100 energy tariffs.

Dura5 and Dura16 battery modules

• Dura5: nominal capacity of 5.12 kWh, a stated lifespan of 8,000 cycles (described as 33% longer lasting than the market standard), charge and discharge at 100 A (1C), IP65 rating, arrays of up to 32 battery modules (164 kWh) per inverter, wall or stack mounting.
• Dura16: nominal capacity of 16.1 kWh, the same 8,000-cycle lifespan, charge and discharge at 130 A, IP65 rating, arrays of up to 12 modules (192 kWh) per inverter, wall or floor mounting.

The company says it was an early builder around time-of-use tariffs, letting households charge and draw stored power at the cheapest times automatically.

Manufacturing, testing and installer feedback

Puredrive states that its systems are developed, engineered and tested in Britain, with the company based in the Cotswolds. It describes a working method built on time spent with installers, learning what performs in real homes and feeding that back into product design. The company presents its manufacturing capability and quality control as the basis of the Duracell partnership, and says its systems are already running in homes to help households store energy and cut grid reliance.

Customer support and recognition

Support is handled by an in-house team that assists both homeowners and installers, with a technical support page offering FAQs and self-help guidance and a support form as the first point of contact. The site reports a rating of 4.6 on Trustpilot based on customer feedback, and lists three awards: Gold Winner at the UKCCF Awards 2025 in both Customer Experience Team of the Year and Small Contact Centre of the Year, and Winner at the Great British Entrepreneur Awards 2025 for Family Business Entrepreneur of the Year. The published testimonials, dated between December 2025 and February 2026, describe engineer visits for battery faults, broadband-related connectivity problems and firmware updates.

Company background and leadership

Puredrive Energy Ltd is registered in England and Wales. The company traces its origins to CEO Mark Millar installing what it describes as the first UK home battery in his own garage more than a decade before the business was founded. Millar frames the company's purpose around making energy costs more predictable for households, and the firm states that its battery systems and EV chargers are intended to help homeowners and businesses store energy, use solar power and take advantage of cheaper off-peak tariffs, as well as keep homes powered during outages.
