Legionella risk assessment in Birmingham

Updated 16 August 2026

Key points

  • Legionella risk assessments in Birmingham are required for any non-domestic premises with a water system that can aerosolise water
  • Your mains water supplier is Severn Trent Water
  • Typical cost: £150 to £600, depending on the size and complexity of the water system
  • Use our cost calculator for a specific estimate

Birmingham's post-industrial economy and ongoing city centre regeneration have produced a wide variety of legionella-relevant premises, from care homes and schools in the residential suburbs to large mixed-use commercial estates at sites like Paradise, Smithfield, and the Jewellery Quarter. The city also has a significant hospital estate including the Queen Elizabeth teaching hospital, several large private hospitals, and a large base of dental practices, all of which fall under the stricter healthcare water safety regime.

Local water supply

The mains water supplier for Birmingham is Severn Trent Water (Severn Trent 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.

Water in the Birmingham area is classed as Soft on the Drinking Water Inspectorate hardness scale (around 72 mg/l as CaCO3), according to MyTapWater water quality data (two agreeing sources - unverified). Harder water lays down scale inside calorifiers, cylinders, and mixing valves, and scale gives legionella a foothold while blunting temperature control, so in hard-water areas descaling and inspection belong in the written scheme of control. Check your supplier's postcode water-quality checker for the figure for your exact supply zone.

Legionnaires' disease in the West Midlands

The most recent regional surveillance figures recorded 71 confirmed cases of legionellosis in the West Midlands in 2023, a rate of 1.2 per 100,000 residents.

71Confirmed cases, West Midlands, 2023
1.2Rate per 100,000 residents

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

Typical cost in Birmingham

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

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.

Legionella enforcement in the West Midlands

Prosecutions for legionella failings are usually brought under the Health and Safety at Work etc. Act 1974, whether by the HSE, a local authority, or (in Scotland) the Crown Office and Procurator Fiscal Service. These cases, recorded in Birmingham and the West Midlands, are drawn from our legionella enforcement tracker, which records each one against its primary source:

Riaar Plastics Limited, 2023 (Manufacturing) — fined £50k. Five people, including members of the public, contracted Legionnaires' disease near a West Bromwich plastics factory in 2020, one needing intensive care. The site's cooling towers were in extremely poor condition.

Isher Hangers (K & S Chatha), 2020 (Manufacturing). The owners of a Birmingham hanger manufacturer failed to control legionella from a cooling tower, ignoring their own consultants' warnings and having no risk assessment, on a site near two hospitals. Each received a 12-week sentence suspended for 12 months, a rare custodial legionella outcome.

The failings behind these cases are consistent: no suitable risk assessment, no written scheme of control, monitoring not carried out, or records that could not show the controls happened. The full dataset is on the enforcement tracker, and legionella fines and prosecutions explains how the courts approach sentencing.

Find a legionella risk assessor in Birmingham

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

Legionella testing labs covering Birmingham

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 Birmingham itself, so the nearest UKAS-accredited labs are listed below — all accept postal samples, and posted sampling is how most premises use them:

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.
