Heat Trust has developed a Heat Cost Calculator that allows a customer to gain an indication of the annual heating and hot water cost for a similar-sized property if it had a modern gas boiler.

It has been developed specifically for use by residential customers only.

It will be most relevant to new build properties that are heat-metered. The results are for information purposes only and it will not provide a bespoke assessment for your particular situation.

To accompany the Heat Cost Calculator, we have developed an accompanying customer information sheet to explain the difference between heating and hot water costs associated with a gas boiler compared to district heating. This customer information sheet also explains that for some customers who are tenants, there are costs which their landlord may collect in a different bill. A suite of frequently asked questions has also been prepared and all the background assumptions are available in a further information document. Please use the links to the tabs on the left to access each of these documents.

We are looking to develop the Heat Cost Calculator further to provide a comparison against electric heating at a future date. The consultation for this has now closed and responses are being analysed. Please see our Consultations page for further updates.
