UK Budget Devolution: Growth in Every Postcode or Empty Promise 2026

Will the UK budget deliver growth in every postcode? That's the question on everyone's lips after John Healey's first budget outlined a major devolution drive. The plan promises to shift power and money from Westminster to local leaders, but skeptics wonder if it's more rhetoric than reality.

The budget set ambitious milestones, including a 2028 commitment to devolve some income tax receipts to mayors of strategic authorities (MSAs). It also pledged that next year, 20% of business rates revenues will go to mayors, rising to 100% by the end of the decade. These are significant fiscal levers that could reshape local economies.

What the Devolution Deal Includes

At the heart of the plan is a new wave of devolution deals across England, with negotiations also underway in Scotland, Wales, and possibly Northern Ireland. The goal is to rewire Britain's political landscape, giving more local control over spending and taxation. According to Healey, this is "the biggest wave of devolution in a generation."

Key elements include:

• Income tax devolution: By 2028, mayors of strategic authorities could receive a share of income tax receipts.
• Business rates retention: Mayors will get 20% of business rates revenues next year, with a path to 100% by 2030.
• Tourism levy: New powers for mayors to impose an overnight visitors levy on hotels and B&Bs.
• Expanded mayoral map: Dozens of new mayors could be elected within two years, each controlling billions in spending.

These measures are designed to give local leaders the tools to drive growth tailored to their areas. But will they work?

The Promise vs. the Practicalities

Andy Burnham's signature phrase, "good growth in every postcode and hope in every heart," encapsulates the ambition. Yet delivering on that promise is fraught with challenges. Not all areas have the same economic starting point, and devolving powers without adequate funding could widen regional inequalities.

For instance, business rates retention may benefit wealthy areas with high property values more than deprived ones. Similarly, income tax devolution could incentivize mayors to focus on high-earning residents rather than broad-based growth. The government insists it will monitor outcomes, but details are scarce.

What It Means for Local Economies

If implemented effectively, devolution could unleash local innovation and investment. Mayors would have a direct stake in growing their tax base, potentially leading to more business-friendly policies and infrastructure projects. The tourism levy, for example, could fund local improvements that attract visitors.

However, without careful design, these powers could also lead to a postcode lottery in public services. The government must ensure that funding formulas account for need, not just tax potential. Otherwise, the gap between prosperous and struggling areas could widen.

Comparing Devolution Models

Different regions will have varying levels of control. The table below summarizes the key differences in the current proposals.

This comparison highlights the scale of the shift. But the success of these policies hinges on execution and oversight.

Challenges and Opportunities

One major challenge is capacity. Many local authorities lack the expertise to manage new fiscal powers effectively. The government has promised support, but training and resources will be crucial. Another issue is accountability: with more power at the local level, voters must be able to hold mayors to account.

On the opportunity side, devolution could foster experimentation. Different regions can try different approaches to growth, and successful models can be scaled. This is the essence of "supply-side economics" that Healey mentioned—giving people the tools to create growth from the bottom up. The background to this story is set out in Business: latest articles.

What to Watch Next

The next milestone is the rollout of 20% business rates retention next year. How mayors use these funds will be an early indicator of success. Also watch for the negotiations with Scotland, Wales, and Northern Ireland, which could set a precedent for asymmetric devolution.

Ultimately, the test will be whether "growth in every postcode" becomes a reality or remains a slogan. With the next election on the horizon, the government will be eager to show tangible results. For now, local leaders are cautiously optimistic but demand clarity on funding and powers. Anyone following the wider picture can start with John Healey's First Budget: Who Wins and Who Pays.
