Legionella risk assessment in Braintree

Updated 15 September 2026

Braintree's textile heritage, from the Courtauld and Warner silk and crepe mills, has left a legacy of large industrial buildings, some now converted to offices, outlets, or apartments with replumbed but often re-routed-in-stages water systems. Freeport Braintree and the town's retail and distribution sites bring heavily used welfare facilities, and rapid housing growth at Great Notley and the town's fringes adds modern boosted systems alongside the older stock. Braintree Community Hospital and a scattering of care homes cover the healthcare end. The town sits in Anglian Water's north Essex supply area.

Local water supply

The mains water supplier for Braintree is Anglian Water (Anglian 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 Braintree area is classed as Very hard on the Drinking Water Inspectorate hardness scale (around 350 mg/l as CaCO₃), according to MyTapWater water quality data (single source - 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: the national picture

UKHSA does not publish a separate surveillance figure for the East of England, 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 Braintree still needs a risk assessment, a control scheme, and the records to show the scheme is being followed.

Typical cost in Braintree

Legionella risk assessment costs in Braintree 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.

Legionella enforcement in the East of England

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. No case in our tracker is recorded in Braintree itself; the cases below are the most recent recorded elsewhere in the East of England, shown as regional context rather than local history. They are drawn from our legionella enforcement tracker, which records each one against its primary source:

Bupa Care Homes (BNH) Limited, 2018 (Care home) — fined £1.5m. An 86-year-old resident died of Legionnaires' disease at a Brentwood care home in 2015, months after refurbishment. The company failed to flush and disinfect the system, the manager lacked training, warnings were ignored and records were falsified. Fined £3m, reduced to £1.5m by the Court of Appeal.

Tendring District Council, 2018 (Local authority leisure) — fined £27k. A member of the public contracted Legionnaires' disease from the water system at the council-run Walton-on-the-Naze leisure centre. HSE found inadequate risk assessments, insufficient staff training and a lack of monitoring across several council leisure sites. Fined £27,000 plus £7,197 costs and a £170 victim surcharge at Colchester Magistrates' Court in December 2018.

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 Braintree

We are building a directory of qualified water hygiene assessors in Braintree 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 Braintree area
• Will quote against a clear scope (number of outlets, inclusion of hot and cold surveys, whether sampling is included)

Legionella testing labs covering Braintree

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 Braintree 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.
