Britain’s Economy Was Bigger Than Thought, but It Never Grew Any Faster
The Office for National Statistics published its annual national accounts benchmarking this morning, and it has raised Britain’s measured economic output.
Cumulative volume growth from 1997 to 2024 has been revised up from 59.2 percent to 61.7 percent. In cash terms the 2024 level is 0.5 percent higher, at 2,905 billion pounds.
Three different numbers are in circulation from this release and they are not interchangeable. The 2.5 is the difference between the two cumulative growth estimates in percentage points, 61.7 against 59.2. Carried through to the level of real output, moving from an index of 159.2 to 161.7 is a relative difference of about 1.6 percent. In cash terms the office puts the 2024 uplift at 0.5 percent. The statistical office’s own article does describe the revisions as adding “2.5 percent to the level of GDP by 2024” — that phrasing is loose against its own figures, and we do not adopt it here.
One consequence is a rewritten recovery date. On the revised figures the economy regained its pre-financial-crisis peak in the second quarter of 2013, a quarter earlier than previously recorded.
The growth path barely moved
The level went up. The pace did not. Average annual volume growth from 1998 to 2024 is unchanged at 1.8 percent, and average quarterly growth is unchanged at 0.5 percent to one decimal place. The mean revision across the annual growth rates is positive 0.06 percentage points.
Recent years shifted by a tenth here and there: 2022 volume growth revised down from 5.1 to 5.0 percent, 2023 up from 0.3 to 0.4 percent, and 2024 up from 1.0 to 1.1 percent. In current prices, 2023 was revised from 6.6 to 6.8 percent and 2024 was unrevised at 5.0 percent.
The office attaches an unusual caution to the most recent year, noting 2024 growth “was estimated to be in a range of 0.8 percent to 1.2 percent” at this stage of the cycle. It is the first year balanced through annual supply-use tables.
What produced the revisions
The largest single change is the first incorporation of the Annual Survey of Goods and Services, applied from 2007 onwards, which improves measurement of the service sector. It raised the secondary production captured by the survey by 35.1 percent in 2023 current prices — this is the measure of secondary products produced by businesses, not a revision to the industrial sector as a whole — with the biggest contributions from business support, professional and scientific activities, and wholesale and retail.
Working the other way, a revised treatment of actual and imputed rentals reduced the GDP level by an average of 0.3 percent across 1997 to 2024. Alignment with the public sector finances took a further 0.1 percent off the level from 2019.
Other inputs include a review of the energy industries covering 2017 to 2024 conducted with the energy department, new estimates of household own-account electricity production, a change to the treatment of precious metals in goods trade, double deflation applied to 2024 volumes, and new survey and administrative data for 2022 to 2024.
The industry picture changed more than the aggregate
Services now account for 81.2 percent of gross value added in 2024, up from 80.4 percent.
Individual industries moved sharply. Financial and insurance activities went from minus 2.2 percent to plus 1.4 percent growth in 2024. Wholesale and retail went the other way, from minus 0.3 percent to minus 3.6 percent. Professional and scientific activities fell from 2.4 to 0.5 percent. Manufacturing rose from 0.3 to 1.5 percent, with pharmaceuticals revised from 0.7 percent to 7.3 percent. Agriculture went from 0.3 percent to 6.5 percent.
The energy industries saw the largest revision of all: the decline over 2019 to 2024 was cut from 42 percent to 24 percent, and electricity, gas, steam and air conditioning growth in 2020 fell from 10.5 to 4.1 percent.
On the expenditure side
Household consumption accounts for most of the downward current-price revision from 1997 to 2006, a consequence of the rentals change, with the effect persisting to 2017 and diminishing sharply thereafter. Gross fixed capital formation contributes upward from 2010. Net trade contributes upward from 2007 and was the largest single upward contribution to the 2023 volume growth revision. Government consumption contributes downward from 2019.
Next
The revised figures enter the official estimates at the quarterly national accounts release on 30 September, with the full Blue Book and Pink Book, and a further revisions article, due on 30 October. This release does not cover the sector or financial accounts, so no revision to the household saving ratio has been published.
