Legionella risk assessment in Selby

Updated 7 September 2026

Selby is a small market town with an outsized industrial hinterland: the nearby power stations and the Ouse corridor's manufacturing and logistics sites bring commercial and welfare-block water systems into the local workload, while the town itself centres on the Abbey, its schools, and a growing commuter population. Much of the housing is post-war estate and older brick terrace, with a private rented sector that brings individual landlords into duty-holder scope. Small industrial estates, haulage depots, and agricultural businesses around the town add premises with showers, canteens, and washdown points that need the same documented controls as larger commercial sites.

Local water supply

The mains water supplier for Selby is Yorkshire Water (Yorkshire Water website). The mains supply is treated and controlled by the supplier, so your legionella duties begin where the water enters your premises. Anything downstream of the boundary stop tap (storage tanks, calorifiers, pipework, outlets) is your responsibility.

Legionnaires' disease: the national picture

UKHSA does not publish a separate surveillance figure for the Yorkshire & Humber, so no regional number is shown here. The most recent national figure recorded 472 confirmed cases of legionellosis across England and Wales in 2024 — the England & Wales average context, not a count for this region.

UKHSA states figures explicitly for only a handful of regions; a full region-by-region table is not published, and surveillance counts only laboratory-confirmed, reported cases, so the national total is a floor rather than the true number of infections. The full picture, with the trend since 2017, is on the Legionella Data Index. The absence of a regional figure changes nothing about your own duties: a non-domestic water system in Selby still needs a risk assessment, a control scheme, and the records to show the scheme is being followed.

Typical cost in Selby

Legionella risk assessment costs in Selby depend more on the water system than on the location. A rough guide:

• Small premises, mains-fed only, no storage: £150 to £250
• Typical office or shop with a hot water cylinder: £200 to £400
• Care home, hotel, or school with stored hot and cold water: £400 to £800
• Premises with a cooling tower or evaporative condenser: from £800, often much higher

Cooling towers drive the cost up because they are notifiable to the local authority under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992, and they need quarterly sampling and extensive cleaning. Get a tailored estimate with our cost calculator.

Find a legionella risk assessor in Selby

We are building a directory of qualified water hygiene assessors in Selby and across the UK. In the meantime, look for assessors who:

• Work for a company registered with the Legionella Control Association (the LCA is the main UK trade body for water hygiene)
• Hold a City & Guilds or equivalent qualification in legionella risk assessment
• Can provide references from similar premises in the Selby area
• Will quote against a clear scope (number of outlets, inclusion of hot and cold surveys, whether sampling is included)

Legionella testing labs covering Selby

Routine temperature monitoring is done on site, but where your risk assessment or written scheme calls for water sampling, the samples go to a laboratory for culture. None of the UKAS-accredited laboratories in our directory is based in Selby itself, so the nearest UKAS-accredited labs are listed below — all accept postal samples, and posted sampling is how most premises use them:

• Feedwater Laboratories (UKAS no. 2234), turnaround ~10 days, from £82.68 per sample
• Eurofins Water Hygiene Testing UK Limited (UKAS no. 9658)
• ALS Environmental (ALS Laboratories (UK) Limited) (UKAS no. 1314)

Methods, turnaround times and published prices for the full directory are compared on the legionella testing labs page. Sampling is not a substitute for day-to-day control: a clear result records what was found at that outlet on that day, it never certifies a system as safe, and it sits alongside the routine checks in your written scheme of control, not instead of them.
