Our commitment
Most things go right at Geko — but when they don't, we want to hear about it and fix it. This policy explains how to raise a complaint, what we'll do, and what your options are if we can't resolve it ourselves.
How to raise a complaint
The fastest way is to email info@geko.energywith the subject line “Complaint”. Please include:
- Your full name and the address of the install.
- Your Geko quote or install reference number (if you have one).
- A description of what's gone wrong.
- What outcome you'd like.
- Any supporting photos or documents.
You can also call us on 07469 828229 or write to Geko Energy Ltd, Alpha House, Terrace Street, Oldham, OL4 1HG, United Kingdom.
What happens next
- Within 1 working day— we'll acknowledge receipt of your complaint by email and assign a case owner.
- Within 5 working days— we'll respond with either a resolution proposal or an explanation of how long we need to investigate.
- Within 8 weeks— we'll give you a final written response. If we need longer (e.g. a third-party warranty claim), we'll explain why and give you a new timeline.
Throughout the process, your case owner is your single point of contact. We'll keep you updated even if we're still working on it.
If you're not happy with our response
If we haven't resolved your complaint within 8 weeks, or you remain unhappy with our final response, you can escalate through one of the independent routes below. All are free for consumers.
