Legionella Risk Assessments & Control in Dorset, Wiltshire, Hampshire & Somerset

Protect Your Business, Staff & Visitors with Safe Water Management

Legionella can cause Legionnaires’ disease, a serious form of pneumonia that can be contracted when people inhale tiny droplets of contaminated water — for example from showers, taps, spray outlets or certain plumbing systems.

At Total Energy Services, we support commercial clients across Dorset, Wiltshire, Hampshire and Somerset with water system improvements and practical control measures designed to reduce Legionella risk and keep systems running safely and reliably.

We’re a trusted, family-run heating and plumbing company based in Blandford, Dorset, working in a wide range of commercial and public premises including schools, hotels, medical centres, churches and community buildings.

What Is Legionella and Why Does it Matter?

Legionella is a type of bacteria that can grow in water systems under certain conditions — especially where water becomes stagnant or sits within the temperature “risk zone”.

The bacteria can multiply more easily in:

• stored water tanks
• poorly maintained hot water systems
• dead legs (pipework sections with little/no flow)
• low-use outlets (rarely used taps/showers)
• systems with scale, corrosion or sediment

If contaminated water becomes aerosolised (fine droplets) and inhaled, it can lead to Legionnaires’ disease — particularly in older people or those with weakened immune systems.

Who Needs Legionella Risk Management?

Legionella risk control is relevant for most premises with water systems, especially:

Hospitality & Tourism

• hotels and rural hotels
• holiday parks and accommodation sites
• pubs with accommodation
• leisure and spa facilities

Education & Community Buildings

• schools and nurseries
• churches and village halls
• sports clubs and community centres

Healthcare & Workplace

• medical centres and clinics
• care settings
• offices and business parks
• warehouses with staff welfare facilities

If your building has any combination of hot water, storage tanks, or multiple outlets — it’s worth taking Legionella risk seriously.

Common Legionella Risk Factors in Commercial Buildings

Many buildings unknowingly have risk factors such as:

• hot water not reaching appropriate temperatures
• cold water warming above recommended levels
• tanks that aren’t insulated correctly
• pipework with dead legs / unused branches
• outlets that are rarely used
• systems that haven’t been serviced for years
• scale build-up reducing temperature control and flow

This is especially common in older rural buildings and community premises like churches, village halls and older schools.

Practical Steps to Reduce Legionella Risk

Legionella control is usually about water temperature, cleanliness, flow and maintenance.

Depending on the building, this can include:

✅ Temperature Control

• ensuring hot water is stored/distributed at safe temperatures
• checking cold water remains cold
• investigating systems where hot water is too low / too slow

✅ System Flushing & Outlet Management

• flushing low-use outlets
• ensuring little-used bathrooms or kitchens are included in a plan

✅ Improving System Layout & Flow

• removing dead legs
• modernising pipework sections
• improving circulation and return loops (where needed)

✅ Servicing of Water Heaters & Hot Water Equipment

• maintaining water heaters, cylinders and controls
• addressing scale issues (especially in hard water areas)
• improving recovery time and temperature stability

How Total Energy Services Can Help

While formal Legionella risk assessments are often carried out by specialist assessors, many businesses need a qualified plumbing/heating contractor to put the control measures into action.

We can support by:

• improving hot water temperature performance
• upgrading or replacing inefficient water heaters / cylinders
• installing point-of-use heaters to reduce stagnation
• replacing outdated valves, controls and pipework
• tidying plant rooms and improving system access
• providing planned servicing for hot water systems
• advising practical improvements for low-use outlets

For many premises, simple system upgrades can massively reduce risk and improve reliability.

Water Systems We Commonly Work On

We support hot water and plumbing systems using common commercial equipment such as:

• Rinnai water heaters
• Andrews water heaters
• Lochinvar water heaters
• Ariston under-sink heaters (for point-of-use supply)
• plant rooms and hot water cylinders
• booster pumps and break tanks (where water flow issues exist)

This makes us well placed to support properties that need both performance upgrades and safer system management.

Legionella Control for Older Buildings (Churches, Halls & Rural Sites)

Some of the most at-risk premises can be buildings that aren’t used every day — where water sits stagnant for long periods.

This is common in:

• churches
• village halls
• community centres
• seasonal holiday accommodation
• low-occupancy buildings

We can help put sensible upgrades in place to reduce stagnation and help maintain safe hot water performance.
