Sunmoon London Ltd, which traded as Sunmoon Energy, is recorded as inactive by the Energy Ombudsman, with a membership period running from 2022-12-01 to 2026-05-051. The company is listed as an energy broker rather than a supplier, with company number 09676886 and membership number C35SUNM011.
The ombudsman states that Sunmoon Energy is not signed up to its scheme, so it cannot review disputes brought against the company1:
"This Energy Broker isn't signed up to our scheme, so unfortunately we can't review your dispute."
The same page carries a general line for consumers whose broker is still trading, advising them to contact the broker directly to confirm its Alternative Dispute Resolution provider1. That wording is written for brokers that remain active; the Sunmoon Energy entry itself is marked inactive1.

The ombudsman page does not state why the membership ended, whether the company has ceased trading, or what has happened to any outstanding complaints. None of that has been reported in the material available1. The page also does not say how many households were affected or whether another body has taken on dispute handling for the firm's former customers1.
Why it matters for households
The Energy Ombudsman is the backstop for unresolved complaints about energy companies in Great Britain, but it can only review disputes involving companies signed up to its scheme1. Where a broker is not in the scheme, that route is closed, and the ombudsman's own page says so plainly1.
For a household, the practical effect is that a dispute with a broker in this position has no ombudsman route. Brokers sit between households and suppliers, and the terms a household agrees through a broker, including any cooling off period when switching energy supplier, are set by that arrangement rather than by the ombudsman scheme. The wider question of how intermediary firms affect a home's energy independence is separate from the ombudsman's remit, which covers complaint handling only.
The ombudsman's page does not set out what a household should do where a broker is inactive, and no alternative dispute route for Sunmoon Energy customers has been reported1.
What happens next
No dated next steps are given. The ombudsman page records the leaving date of 2026-05-05 and an inactive status, and does not state what follows for the company or its former customers1.
