A Critique of the Barnett Formula — and the Alternatives Scotland Could Use Instead

20th June 2026

The Barnett Formula has shaped Scotland’s public finances for nearly half a century. It was introduced in 1978 as a temporary fix, yet it remains the backbone of how Scotland’s block grant is calculated today. For something so central to Scotland’s budget, it is surprisingly controversial — and surprisingly outdated.

Below is a Scotland‑specific critique of the formula, followed by the main alternatives that economists, commissions, and governments have proposed over the years.

1. The Core Criticisms of the Barnett Formula
1. It ignores Scotland’s needs
The formula does not consider:

Rurality

Island geography

Higher health needs

Ageing population

Poverty levels

Transport costs

Energy costs in remote areas

Scotland has higher per‑capita service costs than England, but the formula does not recognise this.

This is the single biggest criticism.

2. It is based on outdated population data
The population share used in the formula is updated only periodically, not annually.

Scotland’s population has grown more slowly than England’s, meaning the formula gradually reduces Scotland’s share — but with a lag that creates distortions.

3. It was meant to be temporary
The Barnett Formula was introduced as a short‑term administrative tool.
It was never designed to last decades or to manage a devolved fiscal system.

Yet it became permanent by default.

4. It does not determine Scotland’s overall funding
This is widely misunderstood.

The formula only adjusts the change in funding — not the baseline.
Scotland’s higher per‑capita spending comes from historical baselines set in the 1970s, not from Barnett itself.

This makes the system opaque and politically contentious.

5. It creates the “Barnett Squeeze”
Over time, the formula pushes Scotland’s per‑capita spending closer to England’s, because increases are population‑based.

In theory, this should equalise spending.
In practice, it has narrowed the gap but not eliminated it.

Critics argue this “squeeze” does not reflect Scotland’s structural needs.

6. It is vulnerable to UK policy decisions
If the UK Government increases spending in England, Scotland gets a share.
If it cuts spending, Scotland’s budget falls.

This means Scotland’s funding is tied to political decisions made for England, not Scotland.

7. It is too simple for a complex fiscal system
Since 2016, Scotland has:

Devolved income tax

Devolved social security powers

Block Grant Adjustments

Tax reconciliations

Borrowing powers

The Barnett Formula was never designed for this level of fiscal complexity.

2. Alternatives to the Barnett Formula
Economists, commissions, and governments have proposed several alternatives.
Here are the main ones — with their implications for Scotland.

Alternative 1: A Needs‑Based Formula
This is the most widely discussed alternative.

It would allocate funding based on measurable indicators such as:

Age profile

Rurality

Health needs

Poverty levels

Transport costs

Population density

Island status

Pros
Fairer and more transparent

Reflects Scotland’s higher service costs

Used in many federal systems (e.g., Australia, Canada)

Cons
Politically contentious

Requires agreement on what “need” means

Could reduce funding for some regions

Impact on Scotland
Most studies suggest Scotland would gain from a needs‑based system because of:

Higher health needs

Rural and island costs

Ageing population

Lower population density

Alternative 2: Full Fiscal Autonomy (FFA)
Scotland would raise all its own taxes and pay a contribution to the UK for shared services (defence, foreign affairs, etc.).

Pros
Maximum control

Clear accountability

Removes Barnett entirely

Cons
Scotland would bear full revenue risk

Volatile tax base (oil, income tax)

Requires major constitutional change

Impact on Scotland
Depends heavily on economic performance.
Could increase flexibility but also increase risk.

Alternative 3: A Hybrid System (Barnett + Needs Adjustment)
This would keep the simplicity of Barnett but add a “needs top‑up” for Scotland, Wales, and Northern Ireland.

Pros
Politically easier than full reform

Recognises structural differences

Maintains stability

Cons
Still tied to England’s spending decisions

Needs assessment could be contentious

Impact on Scotland
Likely positive, especially for health and transport.

Alternative 4: A Per‑Capita Funding Model
Scotland would receive funding strictly based on population, with no historical baseline.

Pros
Simple

Transparent

Cons
Ignores need

Would reduce Scotland’s funding significantly

Impact on Scotland
Negative — Scotland’s per‑capita spending would fall.

Alternative 5: A Federal‑Style Equalisation System
Used in countries like Germany and Australia.

Each region raises its own taxes, and a central fund redistributes money to ensure comparable public services.

Pros
Balances autonomy and fairness

Transparent

Widely used internationally

Cons
Requires major constitutional reform

Politically difficult

Impact on Scotland
Likely positive, depending on the equalisation formula.

3. So What’s the Best Option for Scotland?
There is no perfect system, but most independent reviews (including the Holtham Commission and House of Lords Select Committee) conclude:

A needs‑based formula would be fairer and more transparent than Barnett.

It would reflect Scotland’s:

Higher health needs

Rural and island costs

Ageing population

Lower population density

But it would require political agreement across the UK — which has been elusive.

4. The Bottom Line
The Barnett Formula:

Is simple

Is stable

Avoids annual political fights

But is outdated

Ignores need

Was meant to be temporary

And does not reflect Scotland’s real costs

Most experts agree that reform is overdue.
The debate is not whether Barnett is perfect — it isn’t — but what should replace it, and how Scotland’s fiscal future should be shaped in a changing UK.

Deep dive: How a needs‑based formula would change Scotland’s budget
Let’s treat this like what it really is—a question about fairness, risk, and what Scotland actually needs, not just what it’s historically been given.

1. What a needs‑based formula actually means
A needs‑based formula allocates funding according to measurable indicators of need, not just population or history.

Typical factors:

Age profile

Health needs (chronic illness, disability, life expectancy)

Poverty and deprivation

Rurality and population density

Island and remoteness costs

Housing need and homelessness

Instead of:

“Scotland gets X% because it’s Y% of England’s population”

…it becomes:

“Scotland gets X% because its people are older, sicker, more rural, and more expensive to serve in key areas.”

For Scotland, that shift is huge.

2. Where Scotland’s “needs” are higher than the UK average
Scotland scores above the UK average in several cost‑drivers:

Health: higher rates of long‑term conditions, heart disease, and poor health in deprived areas.

Ageing: a growing older population needing more health and social care.

Rurality: large rural areas with sparse populations.

Islands: Orkney, Shetland, Western Isles—high transport, energy, and service delivery costs.

Deprivation pockets: Glasgow, Dundee, parts of Ayrshire, Inverclyde, etc.

Under a pure population formula, none of this matters.
Under a needs‑based formula, it matters a lot.

3. Where Scotland might gain under a needs‑based system
Health and social care
Scotland’s health needs and geography make delivering services more expensive per person. A needs‑based formula would likely:

Increase Scotland’s relative share of health funding

Justify higher per‑capita spending on social care

Recognise the cost of remote and island healthcare

Transport and infrastructure
Serving remote communities, ferries, rural roads, and island links is structurally more expensive.

A needs‑based formula could:

Allocate more for rural transport

Recognise island connectivity as a cost driver

Support higher capital spending per head

Anti‑poverty and social programmes
Higher deprivation in some Scottish communities would:

Justify more funding for targeted social programmes

Support early years, education, and public health interventions

In short: Scotland’s geography and health profile would likely mean more money per head than a simple population share would give.

4. Where Scotland might not gain—or could even lose
A serious deep dive has to admit this: a needs‑based formula is not a one‑way ratchet in Scotland’s favour.

Areas where Scotland is closer to the UK average
In some services—like certain education metrics or crime rates—Scotland may not stand out as clearly “higher need” than other nations or regions.

Competition with other high‑need areas
A needs‑based system would also recognise:

High deprivation in parts of Northern England

Health needs in Wales

Rurality in Northern Ireland

So while Scotland would likely gain relative to a pure per‑capita model, it would be one of several high‑need territories, not uniquely privileged.

5. How big could the change be?
We can’t put a precise number on it without a full model, but we can outline the direction:

Compared to a pure population formula, Scotland almost certainly gains.

Compared to current Barnett + historic baseline, it’s more nuanced:

In some areas (health, rural transport, social care), Scotland might gain or at least protect its current advantage.

In others, the historic baseline might already be generous, and a strict needs test could trim some of that.

The key point:
A needs‑based formula would lock in Scotland’s higher costs where they are objectively measurable, rather than relying on historical accident.

6. What would change in practice for Scotland’s budget?
More explicit justification
Instead of:

“Scotland gets more because it always has”

…it becomes:

“Scotland gets more because its people are older, sicker, more rural, and more expensive to serve.”

That’s a stronger position in any political argument.

More transparency
A needs‑based system would require:

Regular data on health, poverty, and demographics

Published assessments of relative need

Clear formulas for how money is allocated

Scotland’s funding would be defensible in public, not just in Treasury spreadsheets.

More vulnerability to data
If Scotland’s health outcomes improve, or its demographics shift, its “need score” could fall.
That’s fair—but it also means funding becomes more dynamic and less guaranteed.

7. Political and practical trade‑offs
A needs‑based formula sounds obviously fair—but it comes with trade‑offs:

Winners and losers: some English regions might gain at Scotland’s expense, or vice versa.

Complexity: the system becomes more technical and harder to explain.

Negotiation: every indicator (health, poverty, rurality) becomes a political battleground.

Stability vs fairness: Barnett is simple and stable; needs‑based is fairer but more volatile.

For Scotland, the question isn’t just “Would we get more?”
It’s also:

“Do we want our funding tied to measurable need, even if that changes?”

“Are we comfortable with a system that could both protect and challenge us over time?”

8. The honest bottom line
A well‑designed needs‑based formula would almost certainly:

Recognise Scotland’s higher structural costs

Protect or enhance funding for health, social care, and rural services

Make Scotland’s funding more defensible and transparent

But it would also:

Expose Scotland to more scrutiny and comparison

Reduce the comfort of historical baselines

Force a more grown‑up, data‑driven conversation about what “fair” really means
