What to do when your boiler breaks down in Leicester — repairs, emergencies and replacement

Fast safety checks

1. If you smell gas or suspect a gas leak — get everyone out, avoid using electrical switches or phones inside the property and call the National Gas Emergency Service on 0800 111 999 immediately. Gas leaks are an emergency.  

2. If the boiler is leaking heavily — turn off the boiler and the mains water stopcock if you can reach it safely. Call a local heating engineer; leaks can be caused by corroded pipework, a failed valve, or a damaged heat exchanger.  

3. No heating or hot water? Check your boiler pressure gauge (often a needle or digital readout). Low pressure is a common cause and may be fixable by re-pressurising the system (if you’re comfortable doing this). If you’re unsure, call a Gas Safe registered engineer.  

Common problems Leicester homeowners search for

• “Boiler not working / boiler breakdown Leicester” — causes include loss of power, thermostat faults, or internal component failure. Many local engineers offer emergency callouts.  

• “No hot water but heating works” / “hot water but no heating” — often a diverter valve or pump issue.  

• “Radiators not heating / cold radiators” — could be trapped air (bleed valves), sludge/scale in system, or a failing motorised valve. Radiator repairs and balancing are common local jobs.  

• “Boiler leaking” — may indicate corroded pipework, pressure issues, or internal damage; some leaks require full part replacement or a new boiler.  

When to repair vs replace

• Repair if the fault is a simple, low-cost part (pump, valve, seal) and the boiler is under warranty or less than ~8–10 years old. Regular servicing often prevents these faults.  

• Replace if the boiler is old (frequent breakdowns), the heat exchanger is corroded, repair costs approach the price of a new unit, or if you want a more efficient model to reduce bills. Local Leicester installers advertise rapid replacements and weekend/evening installs for urgent cases.  

Step-by-step: arranging a safe, effective repair or replacement

1. Do the safety checks above (smell of gas, heavy leak, evacuate if needed). Call 0800 111 999 for gas emergencies.  

2. Contact a local Gas Safe registered engineer with good reviews and clear emergency availability. Use local directories (Yell, Checkatrade, TrustATrader, Gas Safe register) to verify.  

3. Get a diagnosis and a written quote before authorising repairs. For replacements, obtain at least two competitive quotes and ask about warranties and efficiency ratings.  

4. Ask about part warranties, operator training and handover (how to use controls, where isolation switches are). A good installer will leave documentation and register warranties.
