New Smart Meter Rights 2026 — What Ofgem’s New Rules Actually Mean For You
THE SHORT VERSION
If your smart meter is not working properly — or you have been waiting too long for a first-time smart meter installation — you now have stronger legal rights.
From 23 February 2026, Ofgem’s new smart meter Guaranteed Standards started applying to suppliers. These are legal obligations, not guidance. If your supplier breaches one of these rules, they may owe you £40 automatic compensation.
Here’s what changed, what is live now, and what is still not in force yet.
What are Guaranteed Standards of Performance?
Guaranteed Standards are legal minimum service levels that energy suppliers must meet.
If they fail, compensation should usually be paid automatically. You should not have to fight for it or take your case to the Ombudsman just to trigger the payment.
Before February 2026, Guaranteed Standards already covered other supplier failures such as missed appointments and delayed payments. From 23 February 2026, smart meter problems were added too.
The three new smart meter rules — in plain English
Rule 1 — The 6 Week Installation Rule
What it says:
If you request a first-time smart meter installation, your supplier must offer a domestic appointment within six weeks.
What it means for you:
If you asked for your first smart meter and your supplier still has not offered you an appointment within six weeks, you may be owed £40.
Important: this rule is about first-time smart meter installs only. It is not a blanket rule for every engineer appointment or every replacement visit.
What to do:
Ask your supplier to confirm the date you first requested the installation. If it has been more than six weeks without an offered appointment, raise a formal complaint and reference GSOP 1.

Rule 2 — The Failed Installation Rule
What it says:
If an engineer attends for a smart meter installation and the installation fails because of something within the supplier’s control, you may be owed £40.
What it means for you:
If the engineer turned up but the job failed because of supplier planning, missing information, supplier systems, wrong equipment, or another issue within the supplier’s control, this may count.
It does not mean every failed visit qualifies. If you were not home, there was no safe access, or there was a genuine site problem outside the supplier’s control, compensation may not apply.
What to do:
Ask your supplier one simple question in writing: “Was this failed installation due to a fault within your control?” If the answer is yes, ask for the automatic compensation payment.

⚠️ The doubling rule — most customers never know this exists
If your supplier fails to pay compensation within 10 working days of the breach, the payment can double under the wider Guaranteed Standards rules.
Example: two failed installation visits, with compensation still not paid on time:
- Failed visit 1 — £40 + £40 = £80
- Failed visit 2 — £40 + £40 = £80
- Total owed: £160
Many customers never realise late compensation can create a second payment. Keep records and check dates carefully.
Rule 3 — The 5 Working Day Smart Meter Investigation Rule
What it says:
If you report a smart meter problem, your supplier must carry out an initial assessment, take any appropriate action that helps identify the issue, and offer to provide written confirmation of what it found and what it did — within 5 working days.
What it means for you:
This is the most important new rule for many customers. Once you report a smart meter problem, your supplier should not just leave the case sitting there. They should assess whether the problem relates to the smart meter, the in-home display, or both, and start taking steps that help identify the cause.
Important: this rule does not say the smart meter must be fully fixed within 5 working days. It is about proper early action, investigation and communication.
A weak response to watch for:
“Thanks for contacting us, we’ve logged your issue and will be in touch.”
That on its own may not be enough if there is no sign of an actual assessment or action.
A stronger response would usually show:
- that the supplier has reviewed the issue
- what it believes may be affecting the meter or IHD
- what checks or actions it has taken so far
- an offer to confirm the outcome in writing
What to do:
If your supplier only sends a generic acknowledgement, reply in writing and ask them to confirm the actual assessment carried out, what action has been taken so far, and whether they are treating the matter as a GSOP 3 case.
Suggested wording:
“Thank you for your response. Under Ofgem’s smart meter Guaranteed Standards, I understand you are required to carry out an initial assessment, take appropriate action to help identify the issue, and offer written confirmation of the outcome within 5 working days. Please confirm what assessment has been completed, what action has been taken, and whether you accept this case falls under GSOP 3.”

💷 Quick reference — what you may be owed
| Situation | Amount |
|---|---|
| Waited more than 6 weeks for a first-time installation appointment | £40 |
| Engineer attended but could not install due to supplier fault | £40 per failed visit |
| Reported a smart meter problem and no proper initial assessment/action followed within 5 working days | £40 |
| Compensation not paid within 10 working days | Additional £40 |
| Smart meter not in smart mode after 90 days | Not live yet — proposed only |
What is still not live yet — GSOP 4
There was a fourth smart meter compensation rule proposed, but it has not been finalised yet.
The proposal was: if your smart meter is not operating in smart mode for more than 90 days, automatic compensation could apply.
The current position: this rule is not in force yet.
Why it has been delayed:
Ofgem says more work is still needed on accountability, technical issues, the role of the DCC, wider smart meter policy, and how responsibility should work where more than one party affects whether the meter is operating properly.
When it may come:
Ofgem says it plans to take final decisions on GSOP 4 in the latter half of 2026.
What to do now:
If your smart meter has been stuck out of smart mode for months, still complain in writing, keep records, and build evidence. Automatic compensation under GSOP 4 is not live yet, but the issue is clearly on Ofgem’s radar.

What happens if your supplier ignores the rules?
- Step 1 — Formal complaint: send a written complaint referencing the specific GSOP breached. Our complaint letter generator helps you do that quickly.
- Step 2 — Keep the evidence: save emails, call dates, screenshots, engineer visit dates, missed promises, and any account notes you can get in writing.
- Step 3 — 8 week deadline: if your complaint is still not resolved after 8 weeks — or your supplier sends a deadlock letter sooner — you can escalate for free.
- Step 4 — Energy Ombudsman: the Ombudsman can order the supplier to put things right, make payments, and explain what went wrong.
- Step 5 — Log everything: the issue timeline is built to help you build a proper timeline of the problem.
The bottom line
Ofgem has given customers real protection here — but most people still do not know these rules exist.
A complaint that cites the right rule, explains the dates clearly, and asks for the correct remedy is far more powerful than a vague email saying “please help.”
Your supplier employs teams of people who understand these regulations. Now you can use them too.
