An information site, not an installer
commercialbatterystorageinstallation.co.uk explains how commercial battery energy storage systems are installed in the UK: the grid connection, the fire strategy and siting, the choice between containerised and indoor systems, the tie-in to live switchgear, and the commissioning that proves it all works. It is written for the facilities managers, energy managers, engineers and directors who have to get a project delivered.
The site does not design, supply, install or commission batteries. It holds no installer accreditations, employs no installation engineers and offers no warranty. Where it mentions MCS, NICEIC or other schemes, it is telling you what to check an installer for, not claiming them for itself.
Why the installation, not the sales pitch
The economics of a commercial battery are usually the easy part. The part that decides whether a project succeeds is delivery: the G99 application and the network operator's connection offer, a G100 limitation scheme where the network is constrained, a fire strategy the insurer accepts, the half-hourly metering, and witnessed commissioning. Those are the parts a buyer most often cannot see in a quote, so they are what this site covers in detail.
How the site is funded
The site is published by SEO Dons Ltd, a UK company (Company No. 16766013, registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ). If you ask for installer quotes through a form on the site, your enquiry is passed to third-party installers who cover your area, who may pay the publisher for the introduction. Some of those installers may also be clients of SEO Dons Ltd for marketing services. That is the commercial model, and it is why the privacy notice says plainly that enquiries are shared with installers. Questions sent through the contact form are answered by the publisher and are not passed on.
The standards this site refers to
- BS 7671:2018+A4:2026, the Wiring Regulations, which added Chapter 57 for stationary battery installations in April 2026.
- The IET Code of Practice for Electrical Energy Storage Systems (3rd edition), the main UK design reference for commercial systems.
- BS EN/IEC 62933 (electrical energy storage systems) and BS EN/IEC 62619 (safety of industrial lithium cells).
- The Energy Networks Association engineering recommendations G98, G99 and G100 for connecting generation and storage to the distribution network.
- The NFCC guidance for fire and rescue services on larger battery sites.
- PAS 63100:2024, which covers battery systems in dwellings. It is often quoted for commercial sites, but it is not the commercial standard.
- CDM 2015, which applies to the construction work on any installation.
The fire safety standards guide maps which of these applies to what, and the checklist for choosing commercial battery storage installers turns them into questions to ask.
What the site does not do
It publishes no install counts, star ratings or testimonials, and no case studies of real installations. The worked examples are illustrative scenarios and are labelled as such. It gives no tax, legal or financial advice: the capital allowances page describes the published rules and says to take your own advice. Cost figures are indicative ranges, not quotes.
