1 Battery. 47 Days. £0 Upfront. Here's How
Energy bills have been squeezing UK businesses for years. For most SMEs, the idea of investing in on-site battery storage sounds appealing in theory, but expensive, complicated, and disruptive in practice. The capital outlay alone is enough to push it to the bottom of a very long to-do list. And even when businesses want to act, the process of figuring out what to buy, who to trust, and how to navigate grid applications can feel like a full-time job in itself.
We've spent a long time at VEST thinking about how to change that. And earlier this year, we proved it can be done differently.
A battery installed: no disruption, no invoice
We partnered with a leisure facility in the UK to install a battery energy storage system on their site. This involved no lengthy procurement process, no internal project team and no budget signed off in a board meeting.
Here's what the whole experience looked like from their perspective:
They signed an agreement with VEST Energy
Grid connection approval took 45 days
Our team completed the physical installation in just 2 days
Total time from signing to a fully operational battery: 47 days
Cost to the site: £0
Since the system went live, they've been saving around 10% on their electricity bill - automatically, every single month, with no ongoing involvement required from them. There are no dashboards they need to monitor, no settings to adjust and no maintenance to arrange. The system simply works, and the savings show up in their bills.
They didn't need to hire a consultant. They didn't need to navigate complicated grant applications or understand the intricacies of grid tariffs. They just said yes, and we handled everything else.
Why we do this and who we do it for
VEST was built around SMEs. Small and medium-sized businesses are the backbone of the UK economy. They keep communities running, keep local families employed, and they're typically the ones who feel energy price spikes the hardest - without the procurement teams, energy managers, or capital reserves that large corporates have to fall back on.
That imbalance has always frustrated us. Large businesses have had access to sophisticated energy tools for years: demand management, power purchase agreements, on-site generation. Meanwhile, the average SME is still just absorbing whatever their supplier charges and hoping it doesn't get worse.
We don't install for homes. We don't chase grid-scale projects. We focus entirely on businesses, because we believe that's where the need is greatest, where the impact per installation is most meaningful, and where the right kind of support has been slowest to arrive.
Our funded battery model means we take on the capital cost entirely and you get the savings. It really is that straightforward but that's also by design.
Simple, trustworthy, quick
We know you've probably seen a lot of energy solutions marketed with bold claims and small print that tells a different story. So let's be clear about exactly how this works:
We assess your site and electricity usage - at no cost and no obligation
If there's a strong fit, we fund and install the battery system - you pay nothing upfront
You start saving on your bills from the first day the system is operational
There's no disruption to your business during the installation process
We manage everything - the paperwork, the grid application, the hardware, the commissioning
We want to be honest with you about timescales too, because we think that matters.
The physical installation at the leisure facility was completed in 48 hours.
The grid connection application, which is handled by the network operator and sits outside our direct control, took 45 days.
That's the real answer to "how long does it take."
We'll always give you an accurate picture, not an optimistic one designed to get you to sign something.
If something is outside our control, we'll tell you that upfront. If a site isn't the right fit for a battery system, we'll tell you that too, rather than waste your time or ours pushing something that won't deliver real savings.
Why now is the right time to act
Energy costs aren't going to resolve themselves. The structural pressures driving UK business electricity prices aren't going away. Businesses that take steps now to reduce their exposure are in a far stronger position heading into the next pricing cycle, and the one after that.
Every month you're operating without a battery is a month you're leaving savings on the table. For a business spending £5,000–£10,000 a month on electricity, a 10% saving isn't a rounding error, it's a meaningful, recurring reduction in one of your biggest fixed costs.
We're also being straightforward about capacity: our summer installation slots are filling up. Battery hardware lead times mean that decisions made now translate into systems live before the end of summer. Decisions made in June might not - and that's months of savings lost that you can never get back.
What happens when you get in touch
There's no sales pitch waiting for you. When you reach out, here's what actually happens:
We have a brief conversation to understand your business and your energy usage
We ask for your HH data, a recent bill and whether there is any existing solar on site.
We carry out a no-cost assessment to determine whether your site is a strong candidate
If it is, we'll put a clear proposal in front of you - straightforward, no jargon
If it isn't, we'll tell you honestly and wish you well
No obligation, no hard sell. You'll simply have more information to make a decision with than you did before.
If you're concerned about your electricity bills, or even just curious about whether a battery system could make a difference for your site, call us (07515 879495) or DM us on LinkedIn.
A conversation costs nothing, and it might be the most valuable 20 minutes you spend on your energy costs this year.
