Glenigan’s September 2026 Construction Review (three months to end-August) shows starts still soft while residential awards and planning approvals strengthen. For contractor-led and Pro teams, the useful move is to separate pipeline from on-site reality — then decide when to lock contingency before you bid private, social or non-residential work as if they were one market.

ConstructUK summarised Glenigan’s September 2026 Construction Review on 17 September 2026, covering the three months to end-August (major and underlying projects; underlying figures seasonally adjusted):
Source: ConstructUK — Glenigan Review: Starts Stall But Contract Awards Point to Recovery (17 Sep 2026).
Earlier the same month, Glenigan’s Index of construction starts (underlying work under £100m, three months to end-August) reported residential starts −15% vs the preceding three months / −36% year-on-year, with private housing −8% q/q / −37% y/y and social housing −29% q/q / −30% y/y. Treat that as the under-£100m cut — the Review figures above are the all-project story we lead with.

Awards climbing while starts stall is not a contradiction — it is a timing gap. SMEs reading the market for the next tender need that split before they stretch labour, plant or quote validity.
A start means work has begun on site. Glenigan’s September Review shows that barometer still weak: overall starts down sharply on the quarter and year, with residential starts −33% year-on-year. Soft starts are crews, draws and supplier risk on jobs that did start — not a full order book.
Main-contract awards and detailed planning approvals describe work entering the pipeline. Residential awards +77% y/y and detailed planning +7% y/y are encouraging signals — they are not cash in the bank or a start date you can staff to yet.
Glenigan’s Index (underlying starts under £100m) for the same three months to end-August shows residential still weaker on that cut (−15% q/q / −36% y/y). Use the September Review for the all-project story; use the Index when you are bidding mid-size underlying work — do not mash the two series into one headline.
This is not a “we win social housing” pitch. Social starts were weak in both the Review and Index cuts. Stronger awards and planning are a medium-term pipeline signal — convert them to committed work and contingency discipline, not a vertical sales claim.
Practical reading of private vs social vs non-residential when bidding — and when to lock contingency if awards outrun starts.
In the Review period, private housing still held the largest residential share but fell hard year-on-year; social housing starts also declined. Non-residential and public verticals (health, community) show different award and approval shapes. Bid the vertical you can actually staff — not a blended “housing is recovering” line.
ConstructUK’s write-up of the Review notes the second-staircase requirement (end of September 2026) may pause or redesign some residential schemes, while levy and viability pressure keep developers reviewing sites. Pipeline strength can sit next to delayed shovels — plan contingency and programme for that lag.
When awards climb and starts stall, price and programme risk often sits in the gap: materials, prelims, and client changes between award and mobilisation. Lock contingency bands and quote validity on remaining work before you treat an award spike as committed turnover.
Seasonally adjusted national figures describe the market, not your tender list. Use Glenigan as context — then update committed vs remaining on each live job from invoices, POs and change orders.
