Why Battery Storage Matters in 2025
Battery storage has evolved from an optional add-on to a central component of modern energy systems. In 2025, the UK market is experiencing rapid adoption driven by:
Time-of-Use (ToU) tariffs – Store low-cost electricity during off-peak hours and use it when rates are higher.
Grid flexibility and resilience – Support the national grid and maintain power during local outages.
Rising demand for self-consumption – Use more of your solar generation instead of exporting it.
LFP (Lithium-Iron Phosphate) chemistry – Offering enhanced safety, longer cycle life, and improved sustainability.
Integration with EV charging and smart homes – Pairing battery storage with EV chargers for maximum efficiency.
According to UK industry insights, home and commercial battery installations are forecast to grow by over 30% in 2025, with systems like Sigenstor and Powerwall 3 leading the transition toward energy independence.
Our Battery Storage Systems
We supply and install modular, scalable battery systems tailored to both domestic and commercial requirements.
Typical configurations range from 5 kWh compact units to 20 kWh+ setups for high-demand homes or small businesses.We install:
Sigenstor Smart Battery Systems – next-generation hybrid energy storage with built-in inverter and intelligent management.
Myenergi Libbi - everything can be monitored and controlled in one app from the range of MyEnergi solutions.
GivEnergy Home Batteries – UK-engineered systems with full app monitoring and cloud connectivity.
Tesla Powerwall 3 – market-leading efficiency and capacity, with seamless solar integration.
Each system is designed to operate safely in domestic settings — including garage, utility room, or loft installations — with compact form factors and silent operation.

Frequently Asked Questions
What size battery do I need?
Most homes benefit from a system between 5 kWh and 10 kWh, depending on your daily energy use, solar generation, and tariff. We size every system individually based on your energy profile.
Can batteries charge from the grid?
Yes. Modern systems such as Sigenstor and GivEnergy allow smart grid charging during off-peak periods, letting you store low-cost electricity for later use.
Can I retrofit battery storage to an existing solar PV system?
Absolutely. We specialise in both hybrid and AC-coupled installations that integrate seamlessly with your existing solar panels and inverter.
Where can batteries be installed?
Typical locations include garages, utility rooms, outbuildings, or lofts. All installations are safety-assessed for ventilation, access, and compliance with UK regulations.
Do batteries provide backup during power cuts?
Yes — depending on the model. The Tesla Powerwall 3 and Sigenstor both include backup power functionality to keep essential circuits running during an outage.
How long do batteries last?
Modern LFP (Lithium-Iron Phosphate) batteries typically provide 6,000 + charge cycles — around 15 years of daily use — and come with up to 10-year manufacturer warranties.
What maintenance is required?
Battery systems are sealed units that require minimal maintenance. Remote diagnostics and firmware updates ensure long-term reliability with no on-site servicing needed.
What are the financial benefits?
Customers typically see 30 – 60 % savings on annual electricity bills by storing solar energy or off-peak grid power. Payback periods vary depending on usage patterns, export tariffs, and battery size.
