Battery Storage

Commercial Battery Storage for UK Sites

Store cheap grid power or your own solar generation, cut peak demand charges, and keep critical operations running through a power cut.

Why Battery Storage

Get more value from every unit of power

Cut peak charges

Shift consumption away from expensive peak-rate electricity by drawing on stored power instead.

Backup power

Keep essential systems running through outages, without relying on diesel generators.

Pairs with solar

Store your own generated solar power instead of exporting it for a fraction of its value.

Our Process

How a Swift battery storage project runs

01

Usage analysis

We review your site's demand profile and any existing solar.

02

System design & quote

Right-sized capacity with a clear ROI projection.

03

Installation

Delivered by our accredited subcontractor network.

04

Monitoring & handover

Live monitoring set up and documentation handed over.

Funding & Incentives

What's available for battery storage

There's no dedicated capital grant for commercial battery storage currently, but the financial case usually stands on its own:

  • Capital allowances — battery equipment typically qualifies for tax relief against profits
  • Peak-rate charge avoidance — savings start from day one of operation
  • Stronger returns when paired with an existing or new solar installation

We build the full payback picture into your feasibility assessment, grant or no grant.

Is Battery Storage Right For You

Who commercial battery storage works best for

A good fit if

  • Sites already generating solar and exporting excess to the grid
  • Businesses on peak/off-peak tariffs with high peak-time usage
  • Sites where a power outage would be costly or disruptive
  • Businesses looking to reduce grid dependency ahead of future EV or heat pump demand

Worth a conversation first if

  • Your site has very low or flat energy usage year-round
  • You don't yet have solar and aren't planning to install it
  • You're not sure yet — a feasibility assessment will tell you
FAQs

Common questions

How long do commercial batteries last?+

Most commercial systems are designed for a long service life, typically with a manufacturer warranty of 10 years or more — we'll confirm specifics for your chosen system.

Can a battery power my whole site during an outage?+

It depends on system size and what you want covered — some clients back up their whole site, others prioritise critical systems only. We size this around your needs.

Do I need solar panels to install a battery?+

No — batteries can charge from the grid during cheap off-peak periods even without solar, though pairing with solar increases the savings.

How is a battery system sized?+

Based on your actual demand profile and goals — whether that's peak shaving, backup power, or maximising self-use of solar.

Does battery storage require planning permission?+

Most commercial installations don't need planning permission, though this depends on size and location — we check this during design.
