Authority: Caerphilly County Borough Council (Local council)
What is being bought5 lots · detail below
Published requirement descriptionCaerphilly County Borough Council (the “Authority”) is seeking to establish a Contract for the Provision of Window Cleaning and Associated Cleans for Caerphilly County Borough Council’s Corporate Properties (the “Contract”).The requirement includes the cleaning of all external glazing, internal communal windows, canopies, and guttering, supporting the overall upkeep of the Council’s estate and helping to prevent deterioration of building fabric. This service will contribute to providing a safe and professional environment for staff, residents, and visitors while maintaining asset value.
Following the original publication of this opportunity, the clarification and tender submission deadlines were subsequently extended and communicated through the Authority's e-tendering system (Proactis). The revised timetable was not reflected in a corresponding notice on Sell2Wales.
This notice is therefore being issued to ensure transparency and equal visibility to the market and to formally publicise the revised procurement timetable applicable to this procurement exercise.
- The authority expects to re-tender this requirement around 1 Jun 2030, 23:59 BST.
- How the procedure runs: As detailed in the tender documents.

How Caerphilly County Borough Council buys Cleaning services (CPV 9091) — and who usually turns up
Caerphilly County Borough Council’s own published record, next to the Wales (Cymru) market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Cleaning services (CPV 9091) →
How the contest usually goes
Left: this authority. Right: the market where the work is delivered. Bids and award-vs-estimate pairs are per lot, from contested contracts only — direct awards (including PA 2023 transparency notices) report one bid by definition and are left out. On Procurement Act 2023 notices the count is the tenders assessed at the final stage, not every submission received; pairs compare like with like (VAT-exclusive, or VAT-inclusive on both sides). Empty means nothing was published, not filled in from elsewhere.

Matched by the nightly worker on class wins, buyer history, delivery geography, scale and notice text; relevance is a 0–100% heuristic score, not a probability of bidding. “Their award vs estimate” is that supplier’s median on its own comparable single-supplier wins, CPV 9091 first. Nobody here is known to be bidding.
Coverage and what to read with care
- Each tile explains itself. The on a figure says what it is, how it is counted and which scope this notice’s own record came from (class, division, all categories, or the authority’s 24-month row). The two columns are never blended and nothing is filled from a UK-wide figure; an empty tile means the source published nothing usable. Long form: Methodology.
- Coverage. Roughly 40 % of notices publish a bid count; about half publish an ITL1 delivery location, so the market column reads the authority’s registered region when the notice has none (labelled). About 30 % of award-vs-estimate pairs are exact matches — the buyer published the award at the estimate. n is on every figure; a thin sample is muted, never hidden.
- “Match” and “relevance” are model scores from the nightly matcher, not published facts. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
