Oral Answers to Questions

Debate between Kieran Mullan and Katie White

Tuesday 2nd June 2026 Commons Chamber

[Dr Kieran Mullan (Bexhill and Battle) (Con)]

2. What steps he is taking to help support the development of deep geothermal energy.

[The Parliamentary Under-Secretary of State for Energy Security and Net Zero (Katie White)]

I pay tribute to the hon. Member for championing deep geothermal. This Government recognise the potential that deep geothermal represents, particularly as a source for heat networks. Our priority is building out heat network infrastructure, which can then connect to any heat source. The green heat network fund and contracts for difference offer opportunities for geothermal projects to demonstrate the potential to de-risk both heat and power.

[Dr Mullan]

Deep geothermal has great potential for left-behind communities in this country, and it is a first-class transition industry for our oil and gas workforce. I welcome the Minister’s comments and the positive engagement with the Minister in the other place, who is a huge champion of deep geothermal, but the message from industry is that that is not enough, and that the funds that the Minister mentions are not doing the job. A deep geothermal strategy, giving the Government’s vote of confidence in deep geothermal, could go a long way, and would not necessarily cost very much. Industry tells us that that in itself would drive growth. Will the Government consider a strategy for deep geothermal?

[Katie White]

I thank the hon. Gentleman once again for championing this issue. I know he has been calling for it, and I welcome the engagement. It was exciting to see the first deep geothermal project being opened in February, as a result of the contracts for difference, and more projects are coming online as a result. We are prioritising the heat network, but I would welcome more conversations with him to ensure that we are making all the right choices.
