No: in Scotland I got a subsidy for the heat pump install capital cost, and I'm on the old feed in tariff scheme that pays me for every unit of energy produced. Including, oddly, energy I consume myself.

It's not so advantageous for new installs because the point of awkwardness in the UK has switched to storage. It's currently possible for some battery owners to make money from arbitrage because the grid hasn't bought enough batteries and north/south links yet.
