Paying for More Electricity Capacity Than You Use? We'll Show You the Savings
Free kVA Capacity Review for Half-Hourly Meter Users
Many businesses overpay for electricity capacity by £3,000–£10,000+ per year without realising it. Our free review identifies exactly how much you could save — no supplier switch required, no obligation, just savings that apply to your current contract.
Why kVA Capacity Reviews Matter
What happens when you ignore excess capacity charges
Paying for Unused Capacity
Many businesses overpay by thousands annually because their kVA was set based on estimates, not actual usage. You're paying for capacity you never use.
Rising Energy Bills Without Reason
Capacity charges compound annually. A 180 kVA setting you don't need could cost £3,200–£5,100 per year that simply disappears into rising bills.
No Visibility Into Your Peak Demand
Without analysing your half-hourly data, you're flying blind. You don't know your actual peak demand, so you can't optimise your kVA setting or negotiate better capacity rates.
Stuck on Outdated Capacity Settings
Without real peak demand analysis, you can't challenge your kVA setting with your DNO. You're locked into capacity charges that were set years ago and may be completely wrong.
A single incorrectly set kVA capacity can waste £10,000+ annually. That's money hemorrhaging from your business every month for electricity capacity you never actually use. A proper kVA analysis could reclaim those savings permanently.
Here's What We Do Differently
We analyse your real 24-month peak demand data directly from your DNO, identify exactly how much kVA capacity you actually need, and coordinate the implementation with your Distribution Network Operator — no supplier switch required, no obligation, just immediate capacity charge reductions.
Why Not Cut Out Your kVA Costs Altogether?
Have a half-hourly meter with low usage? If your consumption is under 100,000 kWh annually, you might be paying kVA capacity charges for sophisticated metering you don't actually need. A Change of Measurement Class (CoMC) could eliminate these costs entirely and reduce your standing charges significantly.

We Access Your DNO Data
We work directly with your Distribution Network Operator to retrieve your actual 24-month peak demand data — the real numbers that determine your ideal kVA.
Receive Your Savings Report
We'll send you a clear, jargon-free report showing your ideal kVA, current overpayment, and exact annual savings. No obligation to proceed.
We Implement Your Savings
If you're happy with the recommendation, we handle everything with the DNO. Your new kVA is applied, and savings appear on your next bill (30–60 days).
Frequently Asked Questions
Everything you need to know about kVA capacity reviews
kVA (kilovolt-ampere) is the maximum amount of electricity your site can draw from the grid in any half-hour period. Your supplier sets this when you sign your contract and charges you a daily capacity charge based on this figure — regardless of how much you actually use. If your kVA is set too high, you're paying for capacity you don't need, potentially costing thousands annually.
You likely don't — that's why our review exists. Your kVA was probably set years ago based on estimates, not your actual usage. Most businesses discover they've been overpaying by thousands once we analyse their real half-hourly data. The only way to know for sure is to look at your 24-month peak demand history — which is exactly what we do.
Just your MPAN (Metering Point Administration Number) and contact details. We retrieve your 24-month half-hourly usage history directly from your Distribution Network Operator. You don't need to provide anything else — we handle the data request with the DNO for you.
The process typically takes 7–14 days. We collect your MPAN (5 minutes), request data from your DNO (5–7 days), analyse it (1–2 days), and send you your savings report (same day). You receive a clear report with no obligation to proceed — take your time deciding.
Absolutely not. This is a free, no-obligation service. You receive your personalised savings report and can decide what to do with the information. If you want to proceed, we handle everything with the DNO. If you'd rather not, that's completely fine — there's no pressure or hidden costs.
It's completely free. There are no charges for the review, analysis, or report. If you decide to proceed with implementation, there are no charges then either. We don't charge any fees — we're here to help you identify and reclaim your savings.
You can always increase your kVA if your business needs change. However, our recommendation is based on your real 24-month peak demand data — if you've never exceeded that peak, you won't need more capacity. We'll discuss this thoroughly in your report so you're confident in the decision.
No. Your electricity supply and service quality remain exactly the same. Reducing kVA only changes what you're charged for capacity — it doesn't affect the reliability or availability of your electricity. You'll still have access to the same electricity; you're just paying for the right amount instead of overpaying.
No, kVA capacity charges only apply to half-hourly (HH) meters. If you're on a standard meter (AMR or manual read), you won't have a kVA charge. However, if you've recently moved to a half-hourly meter or think you might be on one, we can help you check.
Once your new kVA is implemented (typically 30–60 days after approval), your capacity charge on future bills will be lower. The savings compound month-on-month, so a £4,200 annual saving appears as roughly £350 per month on your bill. You'll see the reduction immediately once the change takes effect.
