Southampton Development Exit Report, H1 2026

Methodology and sources

Companies House charges (security instruments, not loans: no amounts, LTVs or rates). Development lending = charges held by specialist development lenders, or by development-active mixed lenders where the borrower carries SIC 41100/41202, the charge wording names development land or a site, or the borrower is a newly incorporated (within 12 months) SIC 68100 company with no buy-to-let SIC (the same rule as the national Development Exit Demand Tracker). Exit-type lending to developers = charges registered by bridging, specialist-bank and private-credit (funder) lenders against companies carrying SIC 41100/41202. A charge is placed by its charged-property postcode, or failing that the borrower's registered office. 'Satisfied' is the filed repayment of a charge: the exit. Exit refinance events are new charges registered on the same title after a specialist development lender's charge was repaid or released (charge stacks, same-group and same-company pairs excluded). Satisfactions are filed late, so the most recent six months are provisional and will rise. Lender categories come from the Construction Capital lender register; lenders are never named.

Land Registry registers new-build plot sales up to a year after completion, so new-build counts, shares and premiums are read only over the settled 12 months ending a year before the data vintage (settled12m) and compared with the 12 months before that. New-build figures in the most recent windows are incomplete and are not used for any headline. HMLR Price Paid, standard (category A) residential sales (detached, semi, terraced, flat) in the location's local authorities. New-build premium compares the median new-build price with the median existing-stock price within flats and within houses; it is a transaction-sample median, not a constant-quality index. Registrations lag completions by weeks to months, so the most recent months (and new-build plots especially) understate final counts; trailing-12-month figures are the steadier read.

Residential planning applications (new build, conversion, prior approval, mixed use, HMO, demolition and rebuild) from the Construction Capital council-portal scrapes, one record set per authority, over each council's rolling 12-month scrape window. Unit counts are stated only on some applications, so totals undercount. Councils not yet scraped are listed as missing, never estimated.

New companies with SIC 41100, 41202 or 68100 by registered-office postcode. The register snapshot holds live companies only, so earlier windows lose companies since dissolved; read year-on-year change as indicative.
