Battery Storage Installation & Integration
Home Battery Installation
Battery systems designed around your household electricity consumption, available space, supply capacity and future energy requirements.
Solar PV Integration
Store surplus electricity generated by your solar panels and use it later, helping reduce the amount of electricity purchased from the grid.
Tesla Powerwall
Assessment and integration of Tesla Powerwall systems, subject to product suitability, site requirements and current manufacturer specifications.
Off-Peak Energy Storage
Explore battery charging during lower-cost tariff periods and using stored energy when electricity prices are higher.
Backup Power
Assess backup options for essential circuits during power interruptions. Backup capability depends on the equipment and installation design.
Electrical Upgrades
Consumer unit assessments, protective devices, earthing arrangements, cabling and other electrical work needed to support a safe installation.
A Properly Designed Installation
Battery storage is more than connecting equipment to a consumer unit. Every installation needs to be assessed for electrical safety, equipment compatibility and grid connection requirements.
- Existing electrical supply and maximum demand assessment
- Battery and inverter compatibility checks
- Earthing, protection and isolation arrangements
- Suitable battery location and manufacturer clearances
- DNO notification or application under G98/G99, where applicable
- Testing, commissioning and appropriate certification
All electrical installation work is assessed against applicable requirements of BS 7671 and relevant manufacturer instructions.

5. Handover: We explain system operation, monitoring and any relevant maintenance considerations.
Frequently Asked Questions
Can I install battery storage without solar panels?
Yes. Some battery systems can charge using grid electricity, potentially benefiting from off-peak tariffs. The financial benefit depends on your tariff, usage and equipment costs.
Will my battery work during a power cut?
Not necessarily. Backup operation requires compatible equipment and an appropriately designed backup arrangement. Standard grid-connected installations may shut down during an outage.
Do I need DNO approval?
Grid-connected battery systems may require notification or prior approval depending on the inverter and overall generating capacity. We assess the applicable G98/G99 process for the proposed installation.
What size battery do I need?
This depends on your daily electricity consumption, solar generation, tariff and desired backup capability. A site assessment helps establish suitable capacity.
