What Health and Safety Issues Arise from Faulty Commercial Heating Systems?

In commercial buildings, heating systems don’t just keep people warm—they’re essential for maintaining a safe and legally compliant environment. But when these systems go wrong, the consequences can be far more serious than a chilly office. From gas leaks to carbon monoxide poisoning, faulty commercial heating systems present real risks to health, safety, and business continuity.

At Pleasant Plumbers, our team of Gas Safe heating engineers in London supports facilities managers, landlords, and commercial tenants by identifying faults before they become hazards. Here’s what you need to know.

1. Carbon Monoxide Exposure

The silent killer. Faulty gas boilers or poorly ventilated flues can release carbon monoxide (CO) — an odourless, colourless gas that can be fatal. In commercial settings like offices, care homes, and schools, CO leaks put staff and the public at serious risk.

Prevent it:

  • Schedule annual gas safety checks
  • Ensure carbon monoxide detectors are fitted and tested regularly
  • Only use Gas Safe registered engineers in London like Pleasant Plumbers

2. Gas Leaks

Faulty connections, old pipework, or failing boilers can result in dangerous gas leaks, which carry the risk of explosion or fire.

Warning signs include:

  • Rotten egg smell
  • Hissing near pipes or appliances
  • Headaches, dizziness, or nausea indoors

Act immediately: evacuate, call the National Gas Emergency line, then contact a professional commercial plumber in London like Pleasant Plumbers to investigate.

3. Overheating & Scalding Risks

A malfunctioning commercial boiler may cause overheated water or uncontrolled radiator temperatures, increasing the risk of burns or scalds—particularly in schools, care settings, and hospitality venues.

Control measures:

  • Use thermostatic mixing valves (TMVs)
  • Regularly test outlet water temperatures
  • Ensure pressure relief valves are operational

4. System Leaks & Slip Hazards

Leaks from boilers, pipes, or radiators don’t just waste water—they can also create slip and fall hazards. In busy commercial settings like office corridors or communal areas, even a small leak can lead to injury and liability.

Solution:

  • Regular visual inspections
  • Prompt repair of any signs of moisture or corrosion
  • Planned preventative maintenance (PPM) contracts

5. Legionella Risk

In systems where water is stored (e.g., old commercial hot water tanks), legionella bacteria can thrive if temperatures aren’t properly maintained, leading to Legionnaires’ disease—a potentially fatal type of pneumonia.

Prevention:

  • Keep hot water above 60°C and cold below 20°C
  • Avoid water stagnation
  • Book a regular inspection with a heating engineer in London like Pleasant Plumbers
