Tendring District Council: one illness, failings across several leisure sites
On this page
Key points
- £27,000 fine plus £7,197 costs and a £170 victim surcharge for Tendring District Council in December 2018, after a member of the public contracted Legionnaires’ disease at the Walton-on-the-Naze leisure centre.
- The HSE found the failings were not confined to one site: inadequate risk assessments, insufficient training and missing monitoring ran across several council leisure centres.
- The case was heard at Colchester Magistrates’ Court under HSWA 1974 section 3(1) — magistrates’ courts now have unlimited fining powers for these offences.
- The council was prosecuted as an operator, not treated differently for being a public body.
- The lesson: a portfolio of similar sites needs portfolio-level control, because an outbreak at one site exposes the regime at all of them.
Tendring District Council was fined £27,000 in December 2018 after a member of the public contracted Legionnaires’ disease from the water system at the council-run Walton-on-the-Naze leisure centre. When the HSE looked beyond that one building, it found the same failures — weak risk assessments, undertrained staff, missing monitoring — at several of the council’s leisure sites.
The case sits in the local authority leisure sector of our legionella enforcement tracker, alongside the far deadlier Barrow-in-Furness outbreak.
What happened
Walton-on-the-Naze’s leisure centre is exactly the kind of premises where a water-system failure finds its victims: a public building full of showers, with warm water systems worked hard by a constant flow of visitors. A member of the public who used the centre contracted Legionnaires’ disease, and the infection was linked to the centre’s water system.
The HSE investigated. What lifted the case beyond a single-site incident was what inspectors found when they widened the lens: the inadequate risk assessments, insufficient staff training and lack of monitoring were not local quirks of one building. They were features of how the council was running water safety across several of its leisure sites.
In December 2018, at Colchester Magistrates’ Court, the council was sentenced for breaching section 3(1) of the Health and Safety at Work etc. Act 1974: a fine of £27,000, costs of £7,197, and a £170 victim surcharge.
The failings the inspectors found
Three failures, each one systemic rather than local:
- Inadequate risk assessments. The documents existed but did not meet the standard — the same failing that runs through the prosecutions record. An assessment that misses the risk is treated as no control at all, which is why BS 8580-1 exists as the benchmark for what an assessment should contain.
- Insufficient staff training. The people doing the checks did not have the competence ACOP L8 expects of them.
- Lack of monitoring. Without routine temperature monitoring and the other scheduled checks, there was no functioning control regime to evidence — at the outbreak site or at the others.
That word “several” is the one that should worry any multi-site operator. One illness at one leisure centre exposed the regime at all of them.
The fine and costs
| Fine | £27,000 |
|---|---|
| Costs | £7,197 |
| Victim surcharge | £170 |
| Charge | Health and Safety at Work etc. Act 1974, section 3(1) |
| Court | Colchester Magistrates’ Court, December 2018 |
| Illness or death | One member of the public contracted Legionnaires’ disease; no death recorded |
Compared with the seven-figure fines elsewhere in the tracker, £27,000 looks modest. The sentencing guideline sizes fines by culpability, harm and the defendant’s means, and a district council is not a national corporation. But the conviction is identical in kind to the million-pound cases: the same Act, the same section, the same findings.
The lesson for duty holders
For anyone running leisure centres or any portfolio of similar public buildings — councils, trusts, operators with multiple sites — the lessons are:
- Standardise the regime across sites. A control regime that depends on each building’s local habits will fail at the weakest site, and the investigation will then read every site’s records.
- Public bodies are prosecuted like anyone else. Operating as a council, trust or charity is no shield; the duty is identical.
- Showers are the exposure point. In a leisure centre the infection route is the shower aerosol, so shower head descaling and disinfection and flushing of little-used outlets are front-line controls, not housekeeping.
- Magistrates can fine without limit. The old £20,000 cap is gone for health and safety offences, so a magistrates’ hearing is not the soft option it once was.

The illness happened at one leisure centre. The failings were found at several. When you run a portfolio, an outbreak anywhere is an audit of everywhere — and the records at every site had better tell the same story.
The starting point is a proper legionella risk assessment per site, backed by a monitoring regime that runs identically across the portfolio and a log book that proves it. The risk assessment builder is an indicative starting point for structuring each assessment; it records and organises what you find, and it never certifies a system as safe.

Frequently asked questions
Why was Tendring District Council fined over legionella?
A member of the public contracted Legionnaires’ disease from the water system at the council-run Walton-on-the-Naze leisure centre. The HSE found inadequate risk assessments, insufficient staff training and a lack of monitoring across several of the council’s leisure sites. Tendring District Council was fined £27,000 plus £7,197 costs and a £170 victim surcharge at Colchester Magistrates’ Court in December 2018, for breaching section 3(1) of the Health and Safety at Work etc. Act 1974.
Can a council be prosecuted for legionella at its own leisure centres?
Yes. A local authority that operates leisure centres is a duty holder like any other operator, and the HSE prosecutes councils in the same way it prosecutes private companies. Tendring District Council is one of several councils in the UK enforcement record — the Barrow-in-Furness outbreak, which killed seven people, was traced to a council-run arts centre. Being the enforcing authority for other people’s premises gives a council no exemption for its own.
Why are leisure centre water systems a legionella risk?
Leisure centres combine the highest-risk features in one building: showers producing aerosol at close range, pools and often spa pools held warm, large and complex hot and cold water systems with long pipe runs, and heavy but intermittent use that leaves outlets standing. The control regime under HSG274 needs to cover every one of those, with shower heads descaled and disinfected, temperatures monitored, and any spa pool run to the HSG282 standard. A failing anywhere in that chain is what members of the public inhale.
What is a victim surcharge in a health and safety case?
The victim surcharge is a statutory charge added to fines in criminal cases in England and Wales, funding victim services. It appears on the sentencing order alongside the fine and costs. In the Tendring case it was £170 on top of a £27,000 fine and £7,197 costs. It is small relative to the fine, but its presence on the order underlines that a health and safety conviction is a criminal sentence with the same trappings as any other.
