Energy Mediation

Billing disputes sorted.
Properly.

Energy billing errors are more common than most businesses realise. Meter reads, standing charges, VAT classifications, contract start dates — all of them can go wrong. We fix it.

What we handle

We take on the supplier, so you don't have to.

Billing error investigation

We review your bills in detail — meter reads, unit rates, standing charges, VAT, and contract terms. We find the error, put a precise figure on it, and tell you what you're owed.

Formal dispute representation

We raise the dispute with the supplier on your behalf. We know the process, the correct escalation routes, and the timescales they're legally bound to.

Ombudsman escalation

If a supplier refuses to resolve the dispute within 8 weeks, we're entitled to escalate to the Energy Ombudsman. We prepare the full case and manage the submission.

Overcharge recovery

Where a supplier has overcharged, we pursue a credit or refund until it's resolved. We've recovered significant sums for clients — including VAT misclassification that had been running for years.

Ongoing monitoring

Once a dispute is resolved, we continue monitoring future bills to make sure the problem doesn't recur. One point of contact, indefinitely.

Many businesses are unaware their energy bills contain errors. Incorrect meter reads, wrong VAT rates (20% instead of 5%), and contract start date discrepancies are among the most common. If you suspect something is wrong, we'll review it — no charge if there's nothing to recover.
Questions about mediation

Common questions.

Does it cost anything to use the mediation service?

No. Like our procurement service, we're paid by the supplier when a resolution is reached. If no money is recovered, there's no fee.

How long do disputes take to resolve?

Simple billing errors are often resolved within 2–4 weeks. Formal disputes can take 6–12 weeks, particularly if Ombudsman involvement is needed.

What if the supplier just ignores us?

We escalate. After 8 weeks without resolution, we're entitled to take the case to the Energy Ombudsman. Suppliers take Ombudsman referrals seriously.

Can you help with VAT disputes?

Yes. Business energy VAT is 20% by default, but many businesses qualify for the 5% reduced rate. If you've been incorrectly charged the higher rate, we'll recover it.
