KVA REVIEWS

Reduce excess capacity charges, lower standing charges, and make sure your electricity supply matches real business demand.

A kVA review assesses whether your agreed electricity supply capacity still matches how your business operates today.

Your agreed capacity is measured in kVA, or kilovolt amperes. It sets the maximum amount of electricity your site can draw from the grid at any one time and forms part of your fixed electricity costs.

If your kVA is set too high, you could be paying for capacity your business does not need.

Capacity charges are one of the most overlooked areas of a business electricity bill.

Your agreed kVA directly influences your standing charges. The higher your agreed capacity, the more you may pay for access to that level of electricity supply, whether you use it or not.

For businesses with half-hourly meters, larger sites, or multiple locations, even small adjustments to agreed capacity can create meaningful savings over time.

A kVA review compares your actual electricity demand against your agreed supply capacity using half-hourly consumption data.

This helps identify whether your current capacity is:

The aim is to find the right balance between cost reduction and operational security.

Once agreed capacity is set, it is rarely reviewed.

But businesses change. Equipment is replaced, operations shift, sites expand or reduce activity, and energy efficiency improvements are made.

Without regular review, your kVA can quickly become outdated.

If your agreed capacity is higher than your site needs, you may be paying more than necessary through inflated fixed charges.

A kVA review can identify excess headroom and highlight opportunities to reduce capacity safely.

This can help lower capacity charges and may also support a lower Targeted Charging Review band, which is a key driver of standing charges for many businesses.

Reducing capacity too far can create risk.

If your site exceeds its agreed capacity, you may face excess capacity charges and potential supply issues.

That is why a kVA review should be based on accurate usage data, not guesswork.

With RIIO-3 running from 1 April 2026 to 31 March 2031, network costs and standing charges are under increased pressure across the UK energy market. Ofgem has confirmed RIIO-3 as the next price control period, covering major network investment and future energy infrastructure.

For businesses, this makes it even more important to check that fixed electricity charges are aligned with real operational demand.

A kVA review can help your business:

At Flame Energy, we help businesses assess and optimise their agreed electricity capacity using detailed consumption data.

Our team reviews your half-hourly usage, identifies whether your kVA is correctly set, and highlights opportunities to reduce avoidable costs without affecting day-to-day operations.

If your agreed capacity has not been reviewed recently, there may be an opportunity to reduce your electricity costs.

Make sure your business is not paying for electricity capacity it does not need.
