Octopus Trusted Partners
How our Octopus partnership works
When Octopus can't carry out a heat pump installation directly - for example, if you're outside their area - they may recommend us as a trusted local partner. Here's what that means for you.
Octopus refers you to us
They share our name and a link to this page. You're free to choose any installer; there's no obligation to go ahead with our quote.
You become our customer
Once you get in touch, our own team handles everything: survey, quote, design, installation and aftercare.
Your contract is with us
Any installation agreement is between you and Lacey Heating Ltd. Octopus Energy isn't a party to the contract and doesn't supervise the work on site.
Recognised by Octopus Energy
Selected, vetted and monitored
When Octopus can't carry out a heat pump installation directly - for example, if you're outside their area - they may recommend us as a trusted local partner.
We're an independent company. Octopus doesn't set our prices or take on our project risk.
