One-off payment. Instant download. Word and PDF. Rules checked 24 October 2026.

Billing is the biggest cause of energy complaints: 58% of the 46,532 cases the Energy Ombudsman accepted between January and June 2026. Many people pay bills they don't have to, because they don't know the rules or which words to use.

What's in the kit

  1. Start-here guide: which letter to use, the rules on one page, and the order to do things
  2. Back-billing dispute: the 12-month rule (SLC 21BA)
  3. Wrong or estimated bill: corrected bill and a plain-English explanation (SLC 21B)
  4. Faulty meter: investigation within 5 working days, and independent testing
  5. Direct Debit too high, and refund of your credit (SLC 27.14 to 27.16)
  6. Affordable repayment plan, plus objection to a forced prepayment meter
  7. Not my bill: previous occupant, after you moved out, or the wrong meter
  8. Formal complaint and request for a deadlock letter
  9. £40 Guaranteed Standards compensation claim (appointments, faults, switching, final bills)
  10. Energy Ombudsman checklist and ready-to-paste case summary

Every letter names the exact Ofgem licence condition or regulation, sets a deadline, asks for a complaint reference and a pause on collection of the disputed amount, and has grey notes you delete before sending.

Cut old charges

Suppliers usually can't bill you for energy used more than 12 months before the bill. Find your line with the back-billing calculator.

Questions

Is this legal advice?

No. It is a set of templates and general information. For advice on your situation, contact Citizens Advice (England and Wales) or energyadvice.scot (Scotland), both free.

Where does it apply?

England, Scotland and Wales, where Ofgem regulates energy suppliers. Not Northern Ireland, which has different rules.

Can't I use free templates?

Yes, and Citizens Advice has some good ones. The kit puts every letter you're likely to need in one place, quotes the exact licence condition or regulation for each problem, and adds the 12-month calculator, the compensation table and an Ombudsman case summary.

What format are the letters?

Editable Word (.docx) and PDF, in one zip file. Most suppliers accept complaints by email, so you can paste the text into an email.

Is it up to date?

Checked 24 October 2026 against Ofgem's licence conditions, the Standards of Performance Regulations (including the smart meter changes from 23 February 2026) and the Energy Ombudsman's rules.
