Residential Renewables: battery storage for homes across the UK

Residential Renewables Ltd is a UK installer focused on home battery storage. The company presents itself as a partner for sustainable energy solutions and now offers battery installation as a complement to an existing solar system. Its core proposition is storing surplus solar generation during the day and charging from cheap off-peak tariffs at night.

The company states that it covers all areas of the UK and describes itself as an experienced energy storage installer. Its listed competencies are NAPIT, City & Guilds 18th Edition, BPEC Solar PV & Battery Storage and NVQ 3.

Adding storage to an existing solar system

A central part of the offer is retrofitting batteries to a solar PV installation that is already in place. According to the company, this is done with an AC-coupled inverter that works alongside the existing system without requiring it to be altered, so a current Feed-in Tariff agreement is unaffected and the household continues to be paid for generated energy while storing the surplus.

Batteries can also be charged directly from the grid to take advantage of low off-peak rates, which the company presents as a way to reduce bills and protect against rising energy costs. Systems are described as suitable for any home or property, with or without solar panels.

Capacity, inverters and monitoring

The company recommends starting with 12 kWh of storage. Because the batteries are modular, capacity can be expanded later, with systems ranging from 5.2 kWh to 47.5 kWh. A GivEnergy AC inverter accepts up to five batteries, reaching the 47.5 kWh maximum, and a household can have two AC inverters wired in parallel for a total charge and discharge rate of 6 kW.

Monitoring and control are handled through an online application and dashboard, accessible from a phone, computer or tablet. The company also states that the battery can be used during a power cut, subject to discussing requirements.

Installation times and warranty

Residential Renewables aims for a turnaround within 30 days from enquiry to installation, noting that lead times vary by system brand. It cites a manufacturer warranty of around 10 to 12 years for professionally installed home batteries, and its product description refers to a 12-year manufacturer warranty on GivEnergy solar batteries. The company adds that modern systems can be expected to last many years beyond that period if properly charged, discharged and maintained.

GivEnergy administration and servicing

The site carries a notice stating that GivEnergy entered administration on 09/04/2026. Residential Renewables says it continues to maintain and install batteries for existing systems and invites owners to get in touch for servicing, battery storage capacity upgrades or general assistance.

Residential focus with business enquiries

Installation work is primarily aimed at residential properties, although the company says it can assist with business enquiries on request. It also highlights after-sale support as part of its service and points readers to Trustpilot for reviews, describing them as five-star. The site lists solar and battery inverter work and battery storage among its services, and notes that a new-generation 9.5 kWh unit is available.
