How does this year’s NHS budget compare historically?

Jeremy Hunt has claimed recently that in 2016/17 the NHS will receive the sixth biggest funding increase in its history. The claim made health economists like us stop in our tracks, as it appears to describe a very different situation for the NHS to the one we recognise.

To check, we decided to calculate for ourselves how this year’s increase compares. We’re afraid to say, although perhaps not surprised given our previous research, that we have a very different figure. We find that – in real percentage terms – this year it is in fact the 28^th largest funding increase since 1975/76.

This might appear a simple issue, but there are important factors to consider for a fair comparison. For clarity this is how we’ve reached our estimate.

The first factor is that full spending data for the NHS in England is not available in a detailed enough form back to the inception of the NHS in 1948. The source we would use is one compiled by the House of Commons Library, and available back to 1975/6. Prior to this only UK data is available, so we can’t make a like-for-like comparison.

Next we need to remove the effect of inflation. This is standard practice when looking at funding over time, to address the fact that while some years’ increases may be larger than others in cash terms, if prices rise by more in those years then the actual additional purchasing power available may in fact be lower. This is done by comparing spending over time to prices in a chosen base year – usually the current year (e.g. 2016/17) – thereby removing the effects of inflation.

Another possible pitfall is that we need to compare like-with-like, and so need to be careful with the distinction between the budget for NHS England (NHSE) and for the Department of Health (DH). The government will often quote the extra £3.8bn for NHSE this year. But as we pointed out in our joint briefing on the Spending Review, the correct measure of total NHS spending is the DH budget, which will rise by the lower figure of £1.8bn. This includes training of staff, investment in public health, regulation of quality, and national planning and support for providers. These are fundamental aspects of the quality of the NHS as a whole, and there is no logical reason to consider just one part of the NHS budget.

The DH budget, or total NHS budget, rise of £1.8bn includes the dedicated DH capital budget. Often comparisons are made excluding the long-term capital investments, but investment in equipment and infrastructure is crucial for high-quality sustainable care, so it is important to consider the whole of the NHS budget.

The proper comparison is to look at the percentage change in real-terms increases in funding. Clearly an increase of £1.8bn would have had a much larger impact in 1975/76 when the budget was around £30bn (in 2016/17 prices) compared to today’s budget of £120bn. It would be 6.7 per cent for the 1975/76 budget, compared to 1.6 per cent today. So the fairest comparison is to measure the real-terms percentage increase in each year.

On this basis we calculate that this year’s total NHS real-spend increase of 1.6 per cent is the 28^th largest increase since 1975/6 (see the chart below).

Getting public spending figures right is important, otherwise they can mislead and detract from the real issues. The fact is that the NHS is halfway through its most austere decade ever, with all NHS services facing huge pressures. Accuracy and transparency about of the scale of the problem are crucial steps toward a solution.

Note: For completeness, the additional £1.8 billion for DH in 2016/17 ranks as the 20^th largest real-terms increase since 1975/76 in value rather than percentage terms. Additionally, for revenue alone this year’s increase ranks as the 31^st biggest since 1972/73. Although these are technically correct, we recommend using percentage terms as explained above.
