Three live schemes can cover most or all of a heat pump install in Scotland: Boiler Upgrade Scheme (£7,500 grant), Home Energy Scotland Loan (interest-free up to £15,000), and Warmer Homes Scotland (free for low-income households).

Eligibility varies. We can walk you through which scheme fits before you commit to anything. The Alto Energy umbrella means we can install MCS-compliant systems while our own MCS certification is in progress.

Common questions

How long does it take?

What if I'm not eligible for any?

We do fixed-quote installs paid directly. No surprises mid-job.
