How the UK Budget Process Works: Inside HM Treasury and the Role of the OBR

How does HM Treasury build a Budget — and who really shapes the final decisions?

In this episode of Negotiating Government, former Chief Secretary to the Treasury David Gauke and former senior Treasury official John Hall explain how the UK Budget process actually works, from early internal negotiations to last-minute fiscal decisions.

They explore:

• How HM Treasury works with the Office for Budget Responsibility (OBR)
• The strategic choices facing the Chancellor ahead of a Budget
• How fiscal rules and “headroom” influence tax and spending decisions
• Why some measures appear late in the process
• When and how businesses can influence Treasury thinking

Drawing on first-hand experience inside government, this episode reveals the months-long negotiation process that sits behind every UK Budget — and what it means for sectors likely to be affected by tax or spending changes.

If you want to understand how to negotiate with the Treasury, anticipate fiscal shifts, or engage government effectively during a Budget cycle, this episode provides an insider’s guide to how decisions are really made.
