§UK HPI July 2026 annual-change forecast
Framing and exact resolver: the target is the UK House Price Index full-file Annual Change field for sourceSeriesId UKHPI:K02000001:all-property-types:annual-change, United Kingdom row, July 2026, first print only. The registered ledger source URL is the GOV.UK UK HPI reports collection; the exact resolving artifact should be the July 2026 data-download full file linked from that collection.
Checked GOV.UK About the UK House Price Index calendar release dates and UK HPI reports collection.↳ The official calendar lists July 2026 UK HPI publication at 9:30am on 16 September 2026; the reports collection also states the July 2026 UK HPI will be published at 9.30am on Wednesday 16 September 2026.Fetched recent official UK HPI headline annual-change prints for the UK from GOV.UK UK HPI monthly summary/report pages.↳ Recent UK annual price-change prints fetched: January 2026 1.3%, February 2026 1.2%, March 2026 0.0%, April 2026 3.8%, May 2026 2.7%, June 2026 2.0%; June also reported monthly change 0.1% and average price GBP272,000.Fetched base-effect anchors from GOV.UK UK HPI July 2025 summary and June 2026 report.↳ July 2025 UK HPI summary reported annual change 2.8%, monthly change 0.3%, and average price GBP270,000; June 2026 report reported annual change 2.0%, monthly change 0.1%, and noted the rate was down from a revised May 2026 estimate of 3.0%.Fetched housing-demand and transactions indicators from Bank of England Money and Credit July 2026 and HMRC monthly property transactions commentary.↳ Bank of England reported house-purchase mortgage approvals decreased to 56,100 in July 2026 from 58,200 in June, net mortgage borrowing decreased to GBP4.3bn from GBP7.7bn, and the newly drawn mortgage rate rose to 4.45% from 4.35%; HMRC reported July 2026 seasonally adjusted residential transactions of 96,710, 2% lower than June 2026, and non-seasonally adjusted residential transactions of 106,620, 3% higher than June 2026.Prior/update/interval: persistence prior is the June 2026 UK HPI annual change of 2.0%, with a reference class/base rate from the six recent first-print annual changes [1.3, 1.2, 0.0, 3.8, 2.7, 2.0], whose mean is 1.83%. For the level-to-annual update, June annual 2.0 plus forecast-assumed July 2026 monthly change 0.4 minus July 2025 monthly base 0.3 gives 2.1%. Components: level 2.0, momentum +0.1 from a normal summer monthly gain versus the 0.3% base month, one-off SDLT base effect mostly fading after the April spike, policy/credit mechanism -0.1 from softer approvals and higher mortgage rates, offset by still-positive completions. Interval method uses the fetched annual-change values themselves as the registered prompt proxy for a change-rate series, treating recent level dispersion as uncertainty over the first-print annual rate rather than realized forecast-error backtesting: sample sigma = 1.32, so 1.28*sigma = 1.69; point 2.1 +/- 1.7 gives an 80% interval of 0.4 to 3.8 after rounding.
Counter-considerations: upside risk is a stronger-than-assumed July NSA price gain if late spring completions and Northern Ireland/Scotland strength lift the UK aggregate, which would land above the interval if the first-print annual change exceeds 3.8%. Downside risk is a sharper credit-led fall or weak London/southern England mix effect, which would land outside the interval below 0.4%. The most important falsifier is a large July 2026 monthly move rather than a revision, because resolution is first print only.
Review disposition: accepted the interval critique by explicitly labeling recent annual-rate dispersion as the uncertainty proxy rather than realized forecast-error dispersion, clarified that the 0.4% July 2026 monthly input is a forecast assumption, and tightened the first-print rule to match the ledger without adding same-day correction exceptions.
