Free Smart Meter Complaint Letter Generator
Your smart meter isn’t working. You’ve called. You’ve waited.
Nothing has changed.
The problem isn’t that you don’t have rights. The problem is
that suppliers know most people don’t know how to use them.
This tool changes that. Answer a few simple questions and we’ll
generate a formal complaint letter that uses the right language,
references the right regulations, and goes to the right people —
in under two minutes.
No legal knowledge needed. No jargon. Just a letter that works.
Who this tool is for
💳 Credit and direct debit customers — smart
meter stopped sending readings, estimated bills, problems after
switching supplier
💰 Prepayment and PAYG customers — topped up
but no credit showing, meter stopped working, disputed debts or
catch-up bills
☀️ Solar, EV and battery customers — SEG export
payments missing or wrong, smart tariff not working, EV not hitting
the cheap rate
What your letter will include
Every letter generated by this tool includes:
- The correct formal complaint language your supplier must respond to
- The specific Ofgem regulation your supplier has breached
- A clear statement of what you want — and by when
- The 90-day rule invoked if your problem has been going on long enough
- Energy Ombudsman escalation warning if applicable
- Priority Services Register language if you or someone in your
home is vulnerable
Your rights — the short version
Under Ofgem’s licence conditions, your supplier must resolve smart
meter issues within 90 days of them being reported.
If they don’t, you can escalate to the Energy Ombudsman — who can
order backdated payments, compensation and remedial action.
Most people never complain formally. Suppliers rely on this.
A formal written complaint — with the right language — changes
everything.
🔒 Privacy guaranteed — everything you enter
stays on your device. We never see, store or transmit any personal
details. The letter is generated entirely in your browser.

Frequently asked questions
Does sending a formal complaint actually make a difference?
Yes — significantly. A formal written complaint triggers a legal
obligation on your supplier to respond within 8 weeks. It also starts
the clock for Energy Ombudsman escalation. Suppliers treat formal
written complaints very differently from phone calls.
What if my supplier ignores the letter?
If you don’t receive a satisfactory response within 8 weeks — or
if your supplier issues a deadlock letter — you can refer your case
to the Energy Ombudsman free of charge. The Ombudsman can order
backdated payments, compensation and remedial action. Suppliers take
Ombudsman referrals very seriously because they cost them money.
Should I send by email or post?
Email first — it’s faster and creates an automatic timestamp.
Always keep a copy of your sent email. For serious cases, follow
up with a printed copy sent by recorded delivery. This gives you
proof of delivery your supplier cannot dispute.
What is the 90-day rule?
Ofgem requires energy suppliers to resolve smart meter issues
within 90 days of them being reported. If your problem has been
going on longer than 90 days, your supplier is in breach of their
licence conditions. Your letter will reference this automatically
if applicable.
What if I’m a vulnerable customer?
If you or someone in your home is elderly, has a medical
condition, disability, mental health condition, or children under
5 — tick the relevant boxes in the tool. Your letter will include
Priority Services Register language, which triggers your supplier’s
enhanced obligations and usually results in faster escalation to
their specialist vulnerable customer team.
Can I use this letter for any supplier?
Yes. The tool covers all major UK energy suppliers including
Octopus Energy, British Gas, OVO Energy, EDF Energy, E.ON Next,
Scottish Power and Utilita. The letter and contact details are
tailored to your specific supplier.
After you’ve sent your letter
The most important thing you can do alongside sending your
complaint letter is log your problem in our
Problem Tracker.
The tracker timestamps your complaint, records every engineer
visit and supplier contact, and builds the evidence pack you’ll
need if this escalates to the Ombudsman. It takes 60 seconds
and costs nothing.
Together — a strong complaint letter and a timestamped tracker
record — give you the best possible chance of a fast resolution
and any compensation you’re owed.
