Barnett formula

The Barnett formula is a mechanism used by the Treasury in the United Kingdom to automatically adjust the amounts of public expenditure allocated to Northern Ireland, Scotland and Wales to reflect changes in spending levels allocated to public services in England, England and Wales or Great Britain, as appropriate.

The formula is named after Joel Barnett, who devised it in 1978^[1] while Chief Secretary to the Treasury, as a short-term solution to minor Cabinet disputes in the runup to planned political devolution in 1979. Despite the failure of that initiative, the formula was retained to facilitate additional administrative devolution in the Conservative Governments of 1979 to 1997 under Prime Ministers Margaret Thatcher and John Major, and then in the context of the political devolution of the Labour Governments led by Tony Blair and Gordon Brown, and the coalition Government of David Cameron. The Government still declares its intention to continue to use it as the basis for funding the three devolved governments.

The Barnett formula is said to have "no legal standing or democratic justification",^[2] and, being merely a convention, could be changed at will by the Treasury. In recent years, Barnett himself has called it a "terrible mistake".^[3] In 2009, the House of Lords Select Committee on the Barnett Formula concluded that "the Barnett Formula should no longer be used to determine annual increases in the block grant for the United Kingdom's devolved administrations... A new system which allocates resources to the devolved administrations based on an explicit assessment of their relative needs should be introduced."^[4]

Following the September 2014 Scottish independence referendum, the Barnett formula came to widespread attention amid concerns that in a last-minute government bid to sway voters against independence, Scotland had been promised continued high public spending.^[5]

How the formula works

The formula consists of a baseline plus increases to central Government funding to Scotland, Wales and Northern Ireland based on increases in public spending in England in comparable programmes, applied in proportion to current populations:^{[2] [6]}

For example, in 2000, the Scottish and Welsh populations were taken to be 10.34% and 5.93% (respectively) of England's population. For programmes in the Department of Health, the comparability factor for Scotland and Wales was 99.7%. Therefore, if £1 billion was to be added to planned health expenditure in England, then the extra amount added to the Scottish block, compared to the year before, would be £1bn x 10.34% x 99.7% = £103 million, and the amount added to the Welsh block would be £1bn x 5.93% x 99.7% = £59.1 million.^[2]

The original calculation was based on incorrect population estimates, and no attempt has been made to adjust for these errors.^[7]

The formula applies only to expenditure on issues which the devolved administrations (as opposed to UK central government) are responsible for. Its principle is that any increase or reduction in expenditure in England will automatically lead to a proportionate increase or reduction in resources for the devolved governments in Wales, Scotland and Northern Ireland. Analogous arrangements apply to categories of expense which are only controlled by some of the devolved governments. The formula is not applied to all public expenditure, but is the default option if no other decisions are made. Expenditure is allocated en bloc, not by service, allowing each devolved administration to allocate these funds as it believes appropriate.

Proportional to population

The ultimate predecessor of the Formula was the 1888 Goschen formula, introduced by George Goschen when Chancellor of the Exchequer, as part of the proposals for Irish Home Rule. This allocated 80% of funding to England (including Wales), 11% to Scotland and 9% to Ireland; hence the Scottish share was 13.75% of the English amount.

By 1970, in preparation for devolution, changes in the relative populations were examined. By then the relative populations were 85% in England and 10% in Scotland, meaning that the new Barnett formula set changes to Scottish expenditure at 10/85th of the change in England (or 11.76%), 2% lower than the change that was being received under Goschen. The population percentages have been recalculated annually since 1999, and the Scottish share of changes was in 2002 set at 10.23% of the English amount.

Political unwillingness to manage the task of making the changes necessary to rebalance existing expenditure meant that the Barnett formula was applied only to changes. Nevertheless, the expectation was that as inflation led to repeated application of the formula, average expenditure per head on devolved services in Scotland would over the years fall nearer and nearer to the English figure (the so-called 'Barnett squeeze').

Details of the funding arrangement can be found in HM Treasury's Statement of Funding Policy.^[8]

Public expenditure by region

Calculating Government spend by region is difficult because some spend (such as roads and hospitals) benefits not just the local population but also visitors to the region, and because some spend (such as defence and debt interest) is deemed to be for the benefit of the entire UK regardless as to where the money is actually spent. There are also the difficulties associated with estimating the populations in different regions. Also, looking at changes in regional spending over time is difficult due to changes in definitions, classifications and accounting rules, and these changes can retrospectively change estimates of spending for a given year.

Estimates of Government spend by region are given in HM Treasury's annual publication Public Expenditure Statistical Analyses (PESA).^[9][10] These estimates of the spend per person have consistently shown highest levels of spending in Northern Ireland, followed by Scotland, then Wales, and finally England. For example:

The persistence of per capita public expenditure being lower in England than the other regions continues to attract calls for the formula to be renegotiated.

As these variations were not ever a consciously decided policy of the Treasury or Parliament, this inequality has been cited as a reason for reform. Moreover, the erosion of these differences over time has been very slow and uneven. The change in Scottish identifiable expenditure as a percentage of English expenditure from 2001/02 to 2012/13 was 121.3%^[12] to 119.0%.^[13] Previous estimates that these differences would disappear in 30 years now appear unlikely.

The average UK total identifiable expenditure on services is approximately £8,788. Instant abolition of the Barnett formula, and adjustment of the four countries' spend to this average would result in a large decrease for each person in Scotland, Wales and Northern Ireland, but an increase of about 3% per person for England.

Although not subject to the Barnett formula, there are also significant variations in identifiable spending between the regions of England, in 2012/13 ranging from £7,638 in the South East (87% of the UK average), to £9,435 in London (107%).^[13]

Based on need

As noted below, no account is made of the amounts raised by taxation in each of the home nations, nor the relevant fiscal need (based on factors such as sparsity of population, cost of travel, unemployment rates, health, age distribution of the population, road lengths, recorded crimes, and numbers of sub-standard dwellings) in each area. The Barnett formula never claimed to address these issues and was a basic calculation on the basis of proportions of the population.^[14][15]

A Needs Assessment Study was undertaken by the Treasury in 1979 in preparation for planned devolution, to assess the relative needs just with respect to the policy areas which were to be devolved (i.e. excluding non-devolved Government spending such as social security). This study was updated in 1993. Both studies found the highest need for devolved services in Northern Ireland, followed by Scotland, then Wales, and finally England. In 1979, Northern Ireland and Scotland received more to spend on services which would have been devolved than the Needs Assessment suggested they should, and Wales less. By 1993, all three countries had increased the gap between the Needs Assessment and actual spend. However, this does not necessarily reflect the total need and spend, including non-devolved services.

Barnett was to eventually view the formula that he devised as unfair. In The Scotsman in January 2004 he wrote, "It was never meant to last this long, but it has gone on and on and it has become increasingly unfair to the regions of England. I didn't create this formula to give Scotland an advantage over the rest of the country when it comes to public funding."

According to Scotland on Sunday,^[17] moving to a needs-based allocation of government finances would cost Scotland around £2.5 billion a year, but the Audit Commission (for England and Wales) concluded in a 1993 report that "needs assessment can never be perfect or fair."

Funding mechanism

Since devolution, once levels of funding for Scotland, Wales and Northern Ireland have been determined by central Government in a spending review using the Barnett formula, the UK Parliament votes the necessary provision to the Secretaries of State for Scotland, Wales and Northern Ireland as part of their central Government departments' Departmental Expenditure Limits (DEL).^[18] The Secretaries of State then make payments to the devolved administrations from the DEL as block grants, which means that they can be spent by the devolved legislatures on any devolved responsibility however they see fit.^[19]

In 2011-12, the Scotland Office Total DEL outturn was £27.567bn,^[20] and from this the block grant to the Scottish Parliament was £26.985bn.^[21] The Wales Office Total DEL outturn was £14.625bn, and the Northern Ireland Office Total DEL outturn was £10.465bn.^[20]

The Barnett formula only applies to the devolved administrations' expenditure classified within DEL, which for Scotland is about 85% of the Scottish Parliament's total budget.^[22] Other sources of income for the devolved administrations include:

• The Annually Managed Expenditure (AME) portion of the grant from central Government. (AME is demand-led funding not subject to limits, e.g. student loans. AME can only be allocated by the devolved administration to the purpose for which it is assigned. Further AME can be drawn from HM Treasury if required, while any unspent AME is returned.^[23])
• Scottish Variable Rate of Income Tax^[19][18]
• Borrowing^[19][18]

Controversy

The Barnett formula is widely recognised as being controversial but there is no consensus on how to change it.

1. It takes no account of different needs or different costs in different areas.
2. It does not affect existing levels of public expenditure, even if relative population shares change.
3. Since existing levels of public expenditure are not allocated in proportion to population, a particular expenditure decision will lead to different percentage changes in different areas.
4. It takes no account of different amounts of tax paid in respect of different areas or of changes in these amounts.
5. It does not apply to divisions of expenditure between the different regions of England.
6. Neither the Barnett formula nor needs-based spending is incentive-compatible, so neither plan would give the territories any fiscal incentive to become more productive.^[24]

English criticisms

Taxation and charges applied in only one nation or region controversially affect the Barnett formula. In one example, the top-up tuition fees introduced in England are counted as additional English public expenditure (as the extra income is spent by the universities) and, therefore, an equivalent amount from the Consolidated Fund, paid for by UK-wide taxation, has been transferred to the Scottish Government. It was argued that this meant that only the English paid tuition fees, yet this money is shared with Scottish universities, despite Scottish students studying at those universities not having to contribute any extra fees.

In contrast, if the Scottish Parliament was to use its tax-adjusting powers (often referred to as the 'tartan tax'), the additional (or reduced) revenue would not be considered in any calculations by the Barnett formula of the block grant for Scotland.

Scottish and Welsh criticisms

The lack of a statutory basis for the formula troubles Scottish and Welsh citizens. The devolution legislation states only that the Secretary of State for Scotland (or Wales) will make a grant of such monies as Parliament makes available. This is seen as relying too heavily on the good will of the Westminster Parliament, and infringing the independence of the devolved Executives.

The Scottish National Party pointed to what has been termed the Barnett squeeze.^[25] They point out that rather than protecting the favourable spending position of Scotland, the Barnett formula steadily erodes that advantage: if a 4% increase is needed in expenditure to cover inflation, Scotland will get an increase of only 3% of its total budget, whereas England will get the full 4% (proportional to population share) – after inflation, that would mean a 1% budget reduction for the Scottish Government.

Opponents of that view claim that these are not cutbacks, merely lower growth, and that spending convergence between the home nations is not a policy objective of the current UK Government or Scottish Government.^[26]

Options for change

In 2009, the House of Lords Select Committee on the Barnett Formula concluded that, "A new system which allocates resources to the devolved administrations based on an explicit assessment of their relative needs should be introduced."^[4]

The Scottish Liberal Democrats commissioned Lord Steel of Aikwood to investigate what options existed for changing the present arrangement. The report of the Steel commission^[27] was published on 6 March 2006 and called for greater fiscal powers for the Scottish Government, similar to the Common Purse Agreement that exists for the Manx Government.

The Scottish National Party has called for full 'fiscal autonomy' or 'fiscal independence' for Scotland. Based on ONS regional accounts data, Scotland's GDP per capita was £25,600, or 96% of the UK average of £26,700 in 2005. This figure excludes oil and gas revenue and when adjusted for this Scotland's GDP per capita would rise from £25,600 to between £30,000 and £31,000.^[28]
