One-Stop Shop for Domestic Retrofit in Essex
Authority: Essex County Council (Local council)
What is being bought
Published requirement descriptionEssex County Council (ECC) is exploring the development of a One‑Stop Shop (OSS) for domestic retrofit to make it easier for residents, homeowners, and landlords to improve the energy performance of their homes. This will support the ambitions of the UK Governments Warm Homes Plan, which sets out we will help people find ways to save money on energy bills and transform our ageing building stock into comfortable, low-carbon homes that are fit for the future.
ECC aims to develop a OSS that provides a comprehensive, end to end customer journey, including project management, that strengthens and grows the local retrofit economy by supporting trusted local installers, assessors, SMEs, and trades. Additionally, the OSS will provide access to funding and financial support, all with tailored advice to residents to enable easier decision making, seamlessly integrating with our existing delivery mechanisms (Warm Homes Local Grant etc.). The OSS will also recognise the importance of area based approaches to deliver retrofit at scale, community‑led retrofit and working with trusted local networks to increase participation, particularly among hard‑to‑reach groups and how this fits in with the Local Power Plan.

It is important to note that this market engagement exercise is not a call for competition and as such you will need to express your interest in any future tender opportunity once the contract notice is published on Find a Tender.
It should also be noted that this market engagement exercise invites individuals and organisations to express an interest in this exercise only, and it is NOT a pre-qualification questionnaire, and is NOT part of any pre-qualification or selection process.
This market engagement exercise is intended as an awareness, communication, and information gathering exercise. An expression of interest is no indication of a commitment to participate in any future tendering process nor does it infer any preferential or special status on those individuals

How Essex County Council buys Consultative engineering and construction services (CPV 7131), and who usually turns up
Essex County Council’s published record next to the market for the same work. Frameworks and DPS are left out: they draw different bid counts. Whole-market view: Consultative engineering and construction services (CPV 7131) →
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.
Local means the winner is registered in the region where that award was delivered. The market figure counts awards delivered in East of England.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners were registered in the region where that award was delivered.
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.
Half of these awards have an award date within 51 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.
Awards are recorded, but published direct routes and bid counts do not establish this buyer’s share.
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.

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.
