Official UK procurement notice
Water Management - Legionella
Authority: Northern Lighthouse Board (Central government)
What is being bought
Published requirement descriptionThe Northern Lighthouse Board has 208 lighthouses protecting the coastline of Scotland, the Northern Isles, The Western Isles and the Isle of Man as well as an office in Edinburgh, and bases in Oban, Inverness, Lerwick and Kirkwall. The lighthouse stations are infrequently visited, with some being annual or biennial maintenance visits of varying lengths as detailed in the requirements document. This should be taken into account in the risk assessment.
Of these buildings 66 have a water system that is supplied from either mains, private or stored water supplied by NLB tender. NLB has a duty to ensure those systems are assessed, compliant and maintained to ensure they pose no risk.
It should be noted on all lighthouse station sites that the water system is used for washing, showering and flushing toilets, bottled water is provided for drinking and cooking. For mains sites bottled water is still the preferred means for drinking water.
All stations with water have UV and particulate filters within the water system, unfortunately the UV system is switched off between visits and is not optimally maintained. NLB supplement the UV system by storing water automatically dosed with a silver stabilised hydrogen peroxide solution at 250 parts per million.

Competition analysis · published record, not a forecast of who will bid
How Northern Lighthouse Board buys Construction work for pipelines, communication and power lines, for highways, roads, airfields and railways; flatwork (CPV 4523) — and who usually turns up
Northern Lighthouse Board’s own published record, next to the Scotland market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Construction work for pipelines, communication and power lines, for highways, roads, airfields and railways; flatwork (CPV 4523) →
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.

| Supplier | Evidence | Last award | Their award vs estimate | Relevance |
|---|---|---|---|---|
| Andrew Sinclair Ltd SME | 2 class wins · 2 lots for this buyer | 10 months ago | no comparable pairs | 74% |
| Leiths (Scotland) Ltd SME | 10 class wins · 1 lots for this buyer | this month | no comparable pairs | 57% |

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 middle value on its own comparable single-supplier wins, CPV 4523 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.
