Phase Energy: solar PV, battery storage and EV charging installation

Phase Energy SE Ltd is a UK solar company that designs and installs bespoke photovoltaic systems, battery storage and electric vehicle charging for residential and commercial clients. The company states it has a team of more than 35 specialists and completes around 50 installations a month, and describes itself as one of the UK's largest solar companies and a leading Growatt installer.

Systems and equipment

The core offer is a tailored solar PV system, designed around each property's consumption and roof characteristics. For storage, Phase Energy installs battery systems that retain surplus daytime generation for use at night or during periods of low sunlight, and presents itself as one of the largest installers for Growatt and Tesla storage products. On the generation side, it identifies Aiko and Tesla as brands it is a trusted installer of. EV charging completes the range, aimed at drivers who want to charge at home.

• Solar PV: high-performance panels, system design and installation for homes and businesses.
• Battery storage: storage of excess solar energy to increase self-consumption.
• EV charging: charging solutions for electric vehicles.

Accreditations and consumer protection

The company operates under the HIES Consumer Code and states that its work carries an insurance-backed guarantee intended to protect customers even if the firm ceases trading. It is NICEIC and MCS accredited, which it presents as evidence that electrical work and renewable installations meet current safety, quality and performance standards. It is also a member of Checkatrade and TrustATrader, directories that verify and publish customer reviews.

Process and timelines

According to the company's own explanations, a project runs from initial consultation and system design through installation to commissioning, with ongoing maintenance and monitoring offered afterwards. It indicates that a typical residential solar installation can be completed in one to three days, although the duration varies with the complexity of the project. On planning, it notes that most residential installations in the UK fall under permitted development rights, with exceptions for listed buildings, conservation areas and other designated zones.

Savings and payment

Phase Energy presents competitive pricing and flexible payment options as part of its effort to make renewable energy accessible. It cites an average reduction in electricity bills of up to 80% for UK homeowners, a figure that depends on energy usage and system size, and notes that adding battery storage can increase savings by shifting consumption away from peak tariff periods.

Two bases in England

The company gives a registered address at Springfield Rag Room, Springfield House, Mill Lane, Maidstone, and lists a second location at 1115 Hessle Road, Hull. Both appear in the contact details published on its site.
