Situated Just A Few miles from Bury St Edmunds, Felixstowe, Ipswich and Woodbridge We Offer battery storage installation, Repair & Maintenance Services Across Suffolk
Installing solar panels is a significant step toward sustainability, but adding a battery storage system is what truly allows you to master your energy usage.
At Smith & Saunders Electrical, we provide advanced battery solutions that capture the surplus energy your solar panels generate during the day, storing it for use when the sun goes down or during peak tariff periods.
Based in Rendlesham, our specialist team helps homeowners and businesses across Suffolk transition from being simple energy producers to becoming energy independent. By retaining your own green electricity instead of sending it back to the grid, you can power your home through the evening and significantly reduce your reliance on expensive utility providers.
A tailored battery storage system does more than just save you money; it provides security and flexibility. Our expert installers work with leading brands such as Anker, Solix, GivEnergy, and Fox, ensuring we can specify a system that matches your specific household capacity and discharge requirements. Whether you are looking for a compact 5kW unit for a smaller home or a large scale commercial storage array, we ensure a professional installation that integrates seamlessly with your existing solar PV setup.
As an MCS certified and NICEIC approved company, we handle the entire process from the technical design and electrical integration to the final configuration of your smart monitoring tools, giving you complete visibility over your stored power.
Beyond the daily savings, battery storage is a future proof investment that adds tangible value to your property. With the current 0% VAT incentive on energy saving materials, there has never been a more cost effective time to upgrade your system.
Our local Suffolk engineers are on hand to provide honest, jargon free advice on the best storage technology for your needs, ensuring you get a system that is reliable, safe, and built to last for thousands of charge cycles.
From Woodbridge to Bury St Edmunds, we are dedicated to helping our community achieve a smarter, greener future through professional electrical excellence.

How long does a home battery storage system last?
Modern Lithium Iron Phosphate (LFP) batteries typically last between 10 and 15 years and are rated for 6,000+ charge cycles. Leading manufacturers such as GivEnergy, Fox ESS, and Anker Solix back their systems with 10-year warranties.
Can I install a battery storage system without solar panels?
Yes. A standalone battery can charge directly from the grid during cheap off-peak hours on smart electricity tariffs. You can then discharge that low-cost energy to power your property during peak price hours, cutting your energy bills without needing solar panels on your roof.
How much money can a battery storage system save on energy bills?
Combining solar PV with battery storage typically reduces grid electricity reliance by 70% to 90%. If charging from the grid on an off-peak tariff (such as Octopus Go or Flux), homeowners can reduce daytime electricity costs by up to 60%.
Will my battery storage system work during a power cut?
Standard grid-tied battery systems automatically shut down during a power outage to protect engineers working on external power lines. However, Smith & Saunders can install an Emergency Power Supply (EPS) module or automatic backup switch, allowing key circuits (or your entire home) to stay powered during a local blackout.
What size battery storage system do I need for my property?
An average UK household uses between 8kWh and 12kWh of electricity per day. A 5kWh to 10kWh battery suits most 2–4 bedroom homes, while larger properties with heat pumps or electric vehicles often benefit from 13kWh to 20kWh+ systems. Our Suffolk team calculates your exact daily usage profile to recommend the correct capacity.
Can I add battery storage to my existing solar panel system?
Yes. We regularly install AC-coupled battery storage systems alongside existing solar PV arrays. This retrofit option connects directly into your main consumer unit without altering your existing solar panels, inverter, or Feed-in Tariff (FiT) payments.
Is there VAT on battery storage installations in the UK?
Residential battery storage installations qualify for 0% VAT under UK government energy-saving materials tax relief. This 0% rate applies to both standalone battery installations and joint solar-and-battery projects.
Where can a battery storage unit be installed?
Batteries can be mounted on internal walls in garages, utility rooms, or under stairs. Many modern batteries (such as Anker Solix and GivEnergy) feature IP65-rated weatherproof enclosures, allowing safe installation on external house walls if indoor space is limited.
How does smart tariff charging work with a battery?
Your battery's smart inverter connects to your home Wi-Fi network and integrates with your energy supplier's app. You can schedule the battery to automatically charge overnight when energy prices are lowest, then use that stored energy during the day when electricity is most expensive.
Do I need DNO approval to install battery storage in Suffolk?
Yes. Connecting energy storage equipment to the grid requires approval or notification with UK Power Networks (the Distribution Network Operator for Suffolk). Smith & Saunders Electrical manages all G98 or G99 DNO applications and paperwork on your behalf.
