Asked by: Desmond Swayne (Conservative - New Forest West)
Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what estimate she has made of the potential impact of the exclusion of refined products from the Carbon Border Adjustment Mechanism from January 2028; and what estimate she has made of the potential impact on the UK economy were refined products to be included in the mechanism.
Answered by Dan Tomlinson - Exchequer Secretary (HM Treasury)
The government recognises the role that refineries play in energy security and the UK’s industrial base. The Government published a call for evidence (https://www.gov.uk/government/calls-for-evidence/future-of-the-uk-downstream-oil-sector/future-of-the-uk-downstream-oil-sector-call-for-evidence) on the future of the fuel sector on 23rd February 2026 in order to help understand the current state of the refining sector.
Following a strategic and technical assessment by HMG, it has been decided not to expand the Carbon Border Adjustment Mechanism (CBAM) to refined oil products in January 2028. Assessing the case for and feasibility of including refined oil products within the Carbon Border Adjustment Mechanism at a later date is a priority. We are continuing to work with the sector to assess the options.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, if she will make an assessment of the potential merits of further income tax power devolution to Wales following her announcement on 17 March 2026 to pursue devolution of income tax powers in England.
Answered by Dan Tomlinson - Exchequer Secretary (HM Treasury)
The Chancellor announced on 17th March that she will set out a roadmap at Budget for giving English regional leaders a share of some national taxes. This will include looking at income tax, alongside other taxes. It is not about new taxes or higher tax rates.
The Welsh Senedd already has significant income tax powers. This was the product of a lengthy process of debate and development, including the Silk Commission’s first report, the Wales Act 2014, and the Wales Act 2017. Consideration of any further income tax devolution would be a matter for discussion between the Welsh and UK Governments and be subject to consensus in Wales and the agreement of both the UK Parliament and the Senedd.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, for what reason Northern Ireland has been allocated £17 million of the £53 million home heating oil support package announced on 16 March 2026; and if she will publish the methodology used to determine that figure.
Answered by James Murray - Chief Secretary to the Treasury
The government has acted quickly to provide timely, targeted support to low-income households struggling with the rising price of heating oils, based on the latest census data.
This means the funding is distributed in line with where the most vulnerable oil-heated homes are concentrated. It is for the Northern Ireland Executive to allocate the funding in Northern Ireland as they see fit.
Asked by: Ben Lake (Plaid Cymru - Ceredigion Preseli)
Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what consultations were had with the (a) fuel distribution industry and the (b) Welsh government on the development of the support package for households in Wales using heating oil and Liquid Petroleum gas as heating methods announced on 16 March 2026.
Answered by James Murray - Chief Secretary to the Treasury
The government has acted quickly to provide timely, targeted support for those households struggling with the rising price of heating oil.
Officials from the Department for Energy Security and Net Zero have coordinated closely with industry since the conflict in the Middle East began, and continue to do so.
I have discussed this support with all devolved government Finance Ministers. In Scotland, Wales and Northern Ireland, it is for the relevant devolved government to deliver support as they see fit.
Asked by: Ben Lake (Plaid Cymru - Ceredigion Preseli)
Question to the HM Treasury:
To ask the Chancellor of the Exchequer, if she will make an assessment of the potential merits of including household Liquid Petroleum Gas (LPG) data in the methodology used to allocate support funding to each UK nation for heating oil and LPG‑heated properties announced on 16 March 2026.
Answered by James Murray - Chief Secretary to the Treasury
The government has acted quickly to provide timely, targeted support to those households struggling with the rising price of heating oil.
In England, Crisis Payments can be provided by local authorities to support the purchase of any form of fuel that is used for domestic heating, cooking or lighting.
In Scotland, Wales and Northern Ireland, it is for the relevant devolved government to deliver support as they see fit.

Question to the HM Treasury:

Answered by James Murray - Chief Secretary to the Treasury

This means the funding is distributed in line where the most vulnerable oil-heated homes are concentrated.
Asked by: Gregory Campbell (Democratic Unionist Party - East Londonderry)
Question to the HM Treasury:
To ask the Chancellor of the Exchequer, if she will consider the potential merits of excluding hybrids cars from the Vehicle Excise Duty Expensive Car Supplement (a) after three years from the date of first registration and (b) when their resale value falls below £28,000.
Answered by Dan Tomlinson - Exchequer Secretary (HM Treasury)
The ECS applies to new petrol/diesel and hybrid cars with a list price of £40,000 or more, while as announced at Budget 2025, from 1 April 2026 the ECS will apply to new zero-emission cars with a list price of £50,000 or more which are first registered on or after 1 April 2025. The additional charge was introduced so that those who can afford to access the most expensive cars make a fair contribution.
The Government continues to view the Expensive Car Supplement (ECS) as a suitable way of distinguishing the more luxury end of the new car market. Although average list prices of cars have increased since the ECS was introduced, nearly two-thirds of petrol, diesel and hybrid vehicles still fall below the £40,000 threshold.
The Government annually reviews the rates and thresholds of taxes and reliefs, including Vehicle Excise Duty and the ECS, to ensure that they are appropriate and reflect the current state of the economy.
