Construction Intelligence
Methodology, publication notes and corrections
We publish official statistics with their original sources, explain definitions and limitations, and keep a clear line between confirmed facts and our interpretation.
Methodology
Figures are taken from official UK statistical releases. Each value records its indicator, reporting period, the date the source released it and its revision number. We do not estimate, model or fill gaps in official data.
Where sources cover different geographies (for example England, Great Britain or the UK) or different periods (monthly, quarterly or rolling annual), we label each figure and do not combine incompatible series without explaining the difference.
Official statistics are often revised. When a source revises a figure, we record the new value as a new revision and keep the earlier value in our records.

Research categories and definitions
Our reporting covers three categories with equal prominence: Residential Construction (housebuilding starts and completions, residential construction output and new orders), Commercial & Industrial Construction (private commercial and private industrial construction output and new orders) and Construction Industry Indicators (company registrations, insolvencies, material prices, labour earnings and overall construction activity).
"Commercial construction" means building and development activity as measured by official construction statistics. It does not refer to commercial property investment prices, rents or yields.
Private commercial, private industrial, public non-housing and infrastructure work are kept as separate statistical categories, exactly as the Office for National Statistics defines them. They are only combined where the source publishes an official total.
Each figure states its geography (United Kingdom, Great Britain or England) and its period. Construction output is monthly; new orders and housebuilding starts and completions are quarterly. Quarterly figures are never presented as monthly figures.
Companies House counts: a company can list several SIC codes. It is counted once in each matching category (for example both commercial building, SIC 41201, and domestic building, SIC 41202) and once in the overall construction total. We publish the number of companies listing both codes so the overlap is visible.
Publication notes and workflow
The UK Construction Market Monitor (Residential & Commercial Construction Intelligence) is planned as a monthly publication. Every report and figure passes through four stages before it is visible:
- Draft — an editor enters figures (manually or by CSV import) and writes the report.
- Under review — a second person checks every figure against the official release and confirms the source's licence and attribution.
- Approved — an administrator approves the content.
- Published — an administrator publishes it immediately or on a scheduled date. Only published, verified figures appear on public pages.
Imported data never overwrite published figures automatically: new or revised values enter as drafts and must be reviewed and approved. Each edition keeps its own permanent web address and is never replaced by the following month's report.
Corrections policy
If we find an error, or an official source revises a figure we have published, we correct the page promptly and record the date and nature of the correction on the affected report. We do not silently change published conclusions.

- 12 October 2026 — Housing starts and completions (England, Q2 2026) were shown using MHCLG's not seasonally adjusted series (Live Table 213) instead of the seasonally adjusted headline series (Live Table 222). Housing starts corrected from 38,510 to 35,910 (+20% on Q2 2025, +6% on Q1 2026). Housing completions corrected from 37,530 to 35,800 (+1% on Q2 2025, −3% on Q1 2026). Earlier quarters and charts now use the seasonally adjusted series.
