What is being bought

Published requirement description

London Borough of Tower Hamlets is recommissioning a borough-wide, world-class adult substance misuse treatment system, aligned with the Combatting Drugs Partnership Strategy (2024–2027). Currently Tower Hamlets commission and deliver a range of substance misuse treatment and recovery services for residents aged 18 plus, collectively branded as “Reset”. These services meet the needs of Tower Hamlet’s residents facing the challenges of substance misuse by equipping individuals with the tools to move towards a life where drugs and alcohol do not negatively impact on themselves, their families, and/or the wider community.

The borough’s substance misuse treatment and recovery services have undergone significant change over the last six years. The “Reset” service model was launched in October 2019, followed by a challenging period of mobilisation during the pandemic years. More recently the borough has seen a substantial increase in investment, through time-limited grant programmes in support of the national drug strategy, From Harm to Hope. This has resulted in a series of iterative, short-term investments to improve the quality and outcomes of services, with the aim of increasing the numbers of individuals accessing and sustaining treatment.

Following a period of review the borough is seeking to re-procure these services; providing an opportunity to build on the successes of the last few years and refresh our model within the context of a more sustainable funding framework.

How the contest usually goes

Winner shares use published awards; bid and price charts use contested lots.

Question for the bid
This buyerTower Hamlets · division 85
The marketHealth and social work services (CPV 85) · Greater London
What to do with it
How often do SMEs win?
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.

Last 36 months.

Buyer: 18 of 39 known-size awards · market: division 85 · Greater London, n=960
46%42%

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
i

How often local firms win similar work.

Winners with a registered address in the delivery region, out of awards with a known address.

Local means the winner is registered in the region where that award was delivered. The market figure counts awards delivered in Greater London.

A local branch does not count if the registered address is elsewhere.

Last 36 months.

Buyer: 42 of 43 known-location awards · market: division 85 · Greater London, n=1,301
98%60%

Most of this buyer’s recorded winners were registered in the region where that award was delivered. More of this buyer’s work stays local than in this market: 98% against 60%, n=43.

How long to a decision?
i

How long buyers here take to decide after bids close.

Middle value in days from the bid deadline to the award date, on competitions that published both.

Only decided tenders count, so slow ones still waiting are not in.

Last 36 months.

Buyer: 13 decided notices · market: division 85 · Greater London, n=190
47 days62 days

Half of these awards have an award date within 47 days of the bid deadline.

How often single-bid or direct?
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.

Last 36 months.

Buyer: exactly 12 of 34 procurements with awards had no recorded rival · market: division 85 · Greater London, n=1,223
35%67%

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.

Past bids do not predict this tender.

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.
