Legionella risk assessment in Berwick-upon-Tweed

Updated 7 September 2026

Berwick-upon-Tweed sits on the border with Scotland at the mouth of the Tweed, and its legionella work is shaped by tourism, fishing, and the surrounding agricultural economy: hotels, pubs with rooms, and self-catering cottages inside the Elizabethan walls, harbour and marine businesses at Tweedmouth and Spittal, and holiday parks along the coast. The historic core's buildings have been converted and re-converted over centuries, so cold water storage and retained pipework are typical survey findings. The wider rural hinterland brings farms, estates, and village halls into scope, with private water supplies common on outlying properties that sit outside the mains-fed regime.

Local water supply

The mains water supplier for Berwick-upon-Tweed is Northumbrian Water (Northumbrian 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.

Northumbrian Water describes the water it supplies in the Berwick-upon-Tweed area as soft to slightly hard (~50-115 mg/l by zone) — the company's own statement, not a measured town figure, so no mg/l value is published (source: Northumbrian Water). Water hardness still matters for scale: scale inside calorifiers, cylinders, and mixing valves gives legionella a foothold while blunting temperature control, so descaling and inspection belong in the written scheme of control. Check the supplier's postcode water-quality checker for the figure for your exact supply zone.

Legionnaires' disease in the North East

The most recent regional surveillance figures recorded 17 confirmed cases of legionellosis in the North East in 2023, a rate of 0.6 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 Berwick-upon-Tweed still needs a risk assessment, a control scheme, and the records to show the scheme is being followed.

Typical cost in Berwick-upon-Tweed

Legionella risk assessment costs in Berwick-upon-Tweed 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 North East 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 Berwick-upon-Tweed itself; the cases below are the most recent recorded elsewhere in the North East 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:

Faltec Europe Limited, 2018 (Manufacturing) — fined £800k. Legionella grew to potentially lethal levels in recirculating cooling water at a car-parts factory in 2014 to 2015; five people including a local resident contracted the disease. The HSE had repeatedly warned of dead legs and damaged drift eliminators.

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 Berwick-upon-Tweed

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

Legionella testing labs covering Berwick-upon-Tweed

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 Berwick-upon-Tweed 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.
