Growing the UK Economy
How effectively Britain turns capital, energy, infrastructure, skills and institutions into rising productivity and living standards — the headline picture, how the pieces connect, and what the data itself shows is constrained. Every figure below traces to an official source; nothing on this page is UK Stat Pack's own forecast or policy recommendation.
Three headline facts
Investment
18.9%
Whole-economy investment (GFCF) as a share of GDP, 2026 Q1 — the lowest of the G7
Current prices, seasonally adjusted. ONS publishes the G7 ranking alongside this measure, using OECD data for the other six countries; those comparators are provisional and subject to revision. ONS, Business investment, Jan–Mar 2026.
Industrial electricity
25.1p/kWh
UK Medium-band price, 2025 H2, vs 10.6p France and 16.7p Germany, same band and period
See Powering Britain for the full international comparison.
Pensions — two separate quantities
£1.07tn funded DB assets
£1.4tn unfunded PAYG liability
Never add or subtract these — one is invested money, the other is a pay-as-you-go promise with no fund behind it.
Total investment (GFCF) as a share of GDP
UK investment averaged 21.3% of GDP across the 1970s and 20.8% across the 1980s, peaking at 24.4% in 1989. It has not been near that since: the 2010s averaged 17.7%, the weakest decade in the series, and the 2020s so far average 18.8%. This is the longest-running weakness in the UK economy, and the thread most of the pages below connect back to.

How the pieces connect
Our reading — a framework, not a finding
This is UK Stat Pack's own way of organising the pages on this site — a conceptual map, not a quantified model. No arrow here carries a measured effect size; it is a way of asking questions, not a claim about how the economy actually works.
Enabling inputs — all required, none sufficient alone
Energy cost and availability · planning and consenting speed · grid and infrastructure capacity · skills and supply chain · capital availability.
The chain this site tracks
Business investment → productive capacity per worker → productivity → real wages, profits and competitiveness → the tax base and household savings → pension assets → reinvestment.
Where this is too simple: GDP does not automatically become living standards, and the productivity-to-income link is more weakly measured than commonly assumed (see the international comparators' own decomposition work, cited on the relevant pages). Government expenditure is not the same as government investment. Capital allocation is not automatically optimal in either direction.
What the data itself shows is constrained
Built from this site's own already-sourced series — not a ranked opinion about which constraint matters most, just what the underlying data actually shows is binding, stalled or structurally smaller than it used to be.
Grid connections are the binding constraint on new supply
NESO's own reform confirms two separate figures that must not be merged: a 283 GW generation/storage pipeline, and separately ~100 GW of new transmission-connected demand (data centres, electrolysers, industrial loads) identified alongside it. NESO's own words: this reform "isn't a silver bullet" — queue admission is not the same as an actual connection.
See the full data →Housebuilding remains well below the government’s own target
England completed 142,040 net additional dwellings in 2025 — short of the 300,000-a-year target, and lower than each of the previous three years, even as the planning approval rate for decided applications sits above 85%. Approvals are not completions.
See the full data →Major residential planning volume has structurally fallen since the financial crisis
Major residential planning decisions ran at roughly 1,700 a quarter in 2000; by early 2026 that was down to around 1,000 a quarter — a lower-volume planning system, not just a slower one.
See the full data →Unfunded public-service pensions are the second-largest government liability — and are excluded from the headline debt figures
The second-largest UK government liability after gilts. Excluded from Public Sector Net Debt (PSND) and Public Sector Net Financial Liabilities (PSNFL) under ESA10 accounting rules (treated as a contingent, not a concrete, liability) — only appears on the broadest measure, Public Sector Net Worth (PSNW). A reader tracking only PSND or PSNFL will not see this £1.4tn liability at all.
See the full data →Business R&D growth is slower once inflation is stripped out
UK business R&D spending has grown steadily in current-price terms, but the real-terms (constant-price) series shows slower, less consistent growth — a reminder that a current-price headline alone can overstate genuine innovation-spending growth.

How this whole module is sourced, and what "evidence class" means
- A — Observed official statistic and B — Official/admin statistic with methodological limitations account for the large majority of figures across this module — official measurements and statutory-body estimates, never a think tank or campaign group where an official series exists.
- C — Derived by UK Stat Pack from official data figures always name their exact formula and inputs — UK Stat Pack's own calculation, never presented as an official statistic.
- D/E — Forecast or scenario (see forecastSource) figures are always labelled as a projection or model output, with who made the forecast stated.
Every section uses the same evidence-classification scheme, above. Where a figure is genuinely disputed by credible parties, or where a publisher acknowledges a defect in its own source, that is shown inline next to the number — never hidden behind a "read more". Every figure across these pages traces to a named official release.
