What this means for your bid
  • “Drain Cleansing” is a dynamic market: the contest is a place on its panel, not a single contract.

Pipeline intelligence · planning stage: how this market runs before the tender is published

Competition for Pipeline, piping, pipes, casing, tubing and related items (CPV 4416), and who usually turns up

COASTLINE HOUSING LIMITED has too little published record in this market to describe on its own. Published market evidence for the same work stands beside whatever it has. This notice is a framework or DPS, so only frameworks and DPS are compared. Whole-market view: Pipeline, piping, pipes, casing, tubing and related items (CPV 4416) →

How the contest usually goes

Question for the bidWhat 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.

Market: CPV 4416 · UK-wide, n=9
89%

Across this market, small firms won 89% of awards with a known supplier size.

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.

Here, local means the winner is registered in the region where that contract was delivered.

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

Last 36 months.

Market: CPV 4416 · UK-wide, n=16
19%

Across this market, 19% of winners were registered in the delivery region.

How long to a decision?
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.

Last 36 months.

Market: division 44 · UK-wide, n=46
77 days

Half of these awards were announced within 77 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.

Market: division 44 · South West England, n=6
50%

Across this market, at least 50% of awarded procurements had no recorded rival.

How many bids did past lots attract?

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?

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.

Last 36 months.

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.

Where the award price may land.

The forecast uses similar awards and the buyer’s estimate. The band covers the middle half of likely prices.

No comparable awards for this lot yet.

A statistical guide from past awards, not a price to bid.

—Priced at call-off
On a framework or DPS the price is agreed on each call-off, so there is no award price to forecast here: the published figure is a ceiling.

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.

    Key Considerations The geographical spread of properties across Cornwall presents logistical and operational challenges that require robust planning and local knowledge so a locally based team will be essential. There is a strong emphasis on social value, sustainability, and local economic impact, which may require additional reporting and commitments. Contractors will be expected to demonstrate alignment with these priorities. The contract will be procured under the Procurement Act and associated Regulations. The contractor will be required to access Coastline's online contractor portal to provide all necessary documentation and confirm completion of all works before the end of every working day.

    The ability to provide planned, reactive, and emergency drain cleansing and maintenance services across Coastline Housing's entire property stock. Services must include blockage clearance both internal and external, high-pressure water jetting, surface water drainage system cleansing and maintenance, CCTV drainage surveys, tankering services, waste disposal, emergency response to flooding internally and externally, and ability to identify, recommend and complete drain repair and maintenance works. Proven experience in delivering services across all areas of work and specified system types Capacity to manage emergency response A commitment to ensure that Coastline meets all Regulatory standards Coastline Housing Ltd are a Living Wage Accredited Organisation and we expect supplier employees who are directly delivering Coastline projects or completing works at Coastline Housing sites to be paid in line with the current living wage.
