291 Harrow Road Housebuilder warranty
Authority: Westminster City Council (Local council)
What is being bought
Published requirement descriptionSuppliers are encouraged to review the Preliminary market engagement document on the Jaggaer Portal. Further detail is below.
The requirement:
The Council requires a housebuilder warranty and insurance policy for the 291 Harrow Road development. The Council, acting as the developer, has appointed a main contractor to undertake pre-construction services and ultimately to construct three towers at the 291 Harrow Road site. In total the three towers will deliver 144 new homes. Construction is due to commence in late 2027.
Council requires a suitable warranty and insurance provider for the new build including cover for the works and structural warranty post-completion.
The requirement is for a 12-year policy, including the two-year defect liability period after the practical completion. It must cover both the private sale and social rent units.
The policy must protect purchaser deposits if the contractor becomes insolvent before completion, a warranty for the private sale building block (which is attached to an existing already insured Private Accommodation Building), and appropriate for both UK and overseas purchasers.
Further detail on the opportunity and requirement are in a draft scope of services available to the market on the Council's Jaggaer eProcurement Portal (link below).

How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Here, local means registered in Greater London.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside Greater London.
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced within 99 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
The market share is a minimum: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
