Frequently Asked Questions
How do I check if I've been overcharged?▼
(1) Compare your bills to industry benchmarks (Ofgem publishes average unit rates by region). (2) Check if you've been on estimated bills for months or years without a meter read. (3) Review your actual usage (meter readings) against the units charged. (4) Check Which? consumer reports comparing supplier rates. (5) Request a detailed account audit from your energy company.
Can I get a refund for overcharged energy bills?▼
Yes. Energy suppliers must bill accurately under Ofgem licence conditions and Consumer Rights Act 2015. If you've been overcharged, you can demand a refund. You can claim back up to 6 years of overbilling under Consumer Rights Act, though suppliers often negotiate shorter periods.
How long does it take to get a refund?▼
Energy companies must respond to complaints within 8 weeks under Ofgem DISP rules. Some may refund within days if the error is clear. If you escalate to Ofgem, it can take 2-6 months for Ofgem to investigate and issue a decision. Keep pushing—they will enforce refunds.
What if my energy company refuses to refund?▼
File a formal complaint with Ofgem at www.ofgem.gov.uk/complaint. Ofgem can: (1) Force the energy company to refund the overcharge. (2) Order compensation for distress and inconvenience. (3) Fine the energy company for breaching licence conditions. Ofgem decisions are legally binding.
How far back can I claim for overcharging?▼
Under Consumer Rights Act 2015, you have 6 years to claim. However, in practice, most energy suppliers will only honour claims going back 3-4 years unless you have clear evidence of continuous systematic overcharging. Ofgem may support claims further back if there's a pattern of breaching licence conditions.
What evidence do I need for an energy bill complaint?▼
Keep: (1) All bills from the past 6 years (or as far back as you have). (2) Your actual meter readings. (3) Proof of what tariff you were on. (4) Any correspondence with your energy company about rate changes. (5) Industry benchmark reports (Ofgem, Which?) showing you were overcharged. (6) The energy company's written refusal to refund (if applicable).
