T1184 - IP20 Blood Sample Collection
Authority: University of Essex (Education)
What is being bought
Published requirement descriptionUnderstanding Society: the UK Household Longitudinal Study (UKHLS) is a longitudinal social survey of households and individuals living in the UK. Data collection began in January 2009 and participants are interviewed annually. In Waves 2 and 3 of the Study (2010-13) a wide range of objective health measures were collected via a nurse visit, including venous blood samples from which we produced a range of analytes, extracted DNA and produced genetic and epigenetic data. A similar exercise is being undertaken at Wave 16 (2024-26), where the nurse visit has been replaced by participants collecting samples/measurements themselves.
This contract covers the data collection and analysis for a further bio-data collection on the Study's Innovation Panel (2027) ahead of a potential roll out on the main Study sample at Wave 22 (2030-32). The Study is designed and managed by the Institute for Social and Economic Research (ISER) at the University of Essex ("the University"). The Principal Investigator of the Study is Professor Michaela Benzeval. Survey fieldwork is carried out by Verian. The Study is funded by the Economic and Social Research Council (ESRC), and pseudo-anonymised data are shared with broader research community.

How University of Essex buys Hospital and related services (CPV 8511), and who usually turns up
University of Essex’s own published record, next to the published market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Hospital and related services (CPV 8511) →
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 East of England.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside East of England.
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 61 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.
Both shares are minimums: 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.
Past bids do not predict this tender.

How did awards compare with estimates?

Where winning prices landed against estimates.

Past prices are a guide, not a bid price.

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.
