Authority: Leeds City Council (Local council)
What is being bought
Published requirement descriptionLeeds City Council’s internal service provider (ISP) for construction and repair works, Leeds Building Services (LBS) are responsible for installing Specialist Flue Systems in line with Gas Safety Regulations. This will involve the design, supply, installation and commission of bespoke flue systems including pressure testing.
The contractors will be expected to survey, design, supply components, install and commission bespoke chimney/flue systems for combustion appliances (mainly natural gas but may on occasion include heating oil and wood pellet fuelled appliances). Each installation will be unique to the individual site. The overall contract may include some maintenance and repair work to existing flue systems.
A typical installation project will include:
- Site survey of proposed location with details of proposed appliances.
- Provide a design compliant with BS EN 13384.
- Supply and install components.
- Commission system to BS EN 15287. To include a positive pressure test where the flue is P1 pressure or above. (This will be the case in the majority of projects). Leakage rates to be less than the maximum permissible listed in IGE UP/10. Provide pressure test result certificate.
- Supply and fit flue notice plate, including the designation of flue as described by BS EN 1443.
- All design, install and commissioning with due regard to Gas Safe technical bulletin 163.
Expected exclusions. Some services may not be provided by the specialist contractor including:
- Removal of redundant flues at the site.
- Installation of condensate drainage pipework.
Leeds City Council are looking to establish a multi-supplier framework (up to three suitably qualified contractors) with mini competition call-off arrangements. The Framework cannot guarantee a minimum volume or value of works and requirements will arise on an ad hoc basis.
The procurement will be conducted as a below threshold tender in line with Leeds City Councils Contract Procedure Rules (CPRs) and the Procurement Act 2023.

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 Yorkshire and the Humber.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered in Yorkshire and the Humber.
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 89 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.
Missing bid counts may hide more single-bid awards. This share is a minimum.
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.
1 bid0% / 28%
2–30% / 11%
4–618% / 44%
7+82% / 17%
How did awards compare with estimates?
i
Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
On a framework or DPS, prices are agreed when work is called off.
Past prices are a guide, not a bid price.
Not comparable on a framework or DPS. The notice sets up a supplier panel and a ceiling value; what the work actually costs is agreed later, on each call-off or mini-competition, and those publish as contract notices of their own. The award-vs-estimate record of this market therefore sits on the call-offs; this page shows it on the contracts, not on the panel that frames them.

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.
