Everything is included.

No, Really.

Nobody likes hidden fees and extra charges. So with the Heat Pump Plan we give you one simple number: your monthly plan payment.

And because we take care of everything, you can sit back and enjoy up to 12 years of comfort and peace of mind.

Market leading support.

Every step of the way, we are there to make sure that you get the best outcomes, year after year. From pre-installation design review through to remote monitoring, and regular maintenance, everything is included in your single monthly payment.

And better still, in the unlikely event that anything does go wrong, we fix it at no cost.

  • All equipment installed as part of your Heat Pump Plan is included.

    Any existing equipment and pipework that is retained as part of your system is not covered by the guarantee.
