+ Tap a problem to open
01 Why Are All My Radiators Cold Even Though the Boiler Is Running? The boiler appears to operate but heat is not reaching the radiators +
QUICK ANSWER

If the boiler appears to run but every radiator stays cold, the problem may involve heating circulation, controls, valves or another part of the central-heating system.

Possible causes

  • Heating circulation problem
  • Controls or thermostat fault
  • Zone or motorised valve issue
  • Pump or system-flow problem
  • Boiler heating-mode fault

Safe checks you can make

  • Check normal thermostat settings
  • Check the heating programme
  • Check boiler pressure
  • Look for a fault code
  • Check whether hot water still works
NO HEAT TO RADIATORS?Boiler running but radiators still cold?

The wider heating system may need fault diagnosis to establish why heat is not circulating correctly.

02 Why Is One Heating Zone Not Working? One floor or section of the property stays cold while another heats normally +
QUICK ANSWER

If one heating zone works and another does not, the fault may involve zone controls, thermostats, valves or circulation serving that particular part of the system.

The issue may involve

  • Zone thermostat
  • Motorised valve
  • Heating controls
  • System circulation
  • Zone-specific pipework or valves

Useful information

  • Which zone is affected
  • Whether other zones work normally
  • Whether the thermostat responds
  • Whether the fault is intermittent
  • Whether the boiler fires when that zone calls for heat
ZONE PROBLEM?Only part of the property heating?

Tell us which zone or floor is affected and whether the remaining heating works normally.

03 Why Does My Heating Keep Losing Pressure? The sealed system needs topping up more frequently than expected +
QUICK ANSWER

Repeated pressure loss can be caused by a leak somewhere in the heating system or by a boiler-side pressure problem. Continually restoring pressure without finding the cause is not a long-term solution.

Possible sources

  • Radiator valve leak
  • Heating pipework leak
  • Pipe fitting or connection
  • Boiler-side pressure fault
  • Expansion-related problem

Useful checks

  • Record pressure when the system is cold
  • Look around radiator valves
  • Check accessible heating pipework
  • Look underneath the boiler without opening it
  • Note how quickly the pressure drops
RECURRING PRESSURE LOSSConstantly topping up the heating?

Arrange diagnosis so the underlying source of the pressure loss can be identified.

04 Why Is My Central Heating Making Gurgling or Flowing Noises? Noises are coming from radiators, pipework or the wider system +
QUICK ANSWER

Gurgling or flowing-water noises can relate to trapped air, circulation or system-flow conditions. The cause depends on where the noise occurs and whether heating performance is also affected.

The problem may involve

  • Trapped air
  • Heating circulation
  • System pressure
  • Radiator flow
  • Pipework or valves

Useful information to record

  • Where the sound comes from
  • When the sound starts
  • Whether radiators heat normally
  • Whether pressure is stable
  • Whether the noise is getting worse
NOISY HEATING SYSTEM?Noise affecting normal operation?

Tell us where the noise is coming from and whether any radiators or heating zones are also affected.

05 Why Does My Heating Turn Off Before the House Is Warm? The system stops heating even though rooms have not reached the expected temperature +
QUICK ANSWER

Heating that shuts off too early may involve the thermostat, its location, control settings, communication between controls or another heating-system issue.

Possible causes

  • Thermostat behaviour
  • Thermostat location
  • Programmer settings
  • Wireless controls issue
  • Another system-control fault

Safe checks

  • Check target temperature
  • Check programmed heating times
  • Check thermostat batteries where applicable
  • See whether the boiler stops at the same time
  • Note which rooms are still cold
CONTROL PROBLEM?Heating switching off too soon?

A heating engineer can help determine whether the issue is related to controls or another part of the system.

Check Heating Controls →
06 What Should I Do If My Central Heating System Is Leaking? Water is appearing around radiators, pipework, valves or heating connections +
QUICK ANSWER

A central-heating leak can come from radiator valves, fittings, pipework or another system component. Persistent water loss can also cause boiler pressure to fall and should be investigated.

Possible leak points

  • Radiator valves
  • Radiator connections
  • Heating pipework
  • Pipe fittings
  • Boiler connections

Safe actions

  • Keep water away from electrical equipment
  • Note where water becomes visible
  • Check whether boiler pressure is falling
  • Do not dismantle heating components yourself
  • Report a significant or worsening leak promptly
HEATING SYSTEM LEAKWater continuing to escape?

Arrange heating-system diagnosis so the source of the leak can be identified and repaired.

Report Heating Leak →
07 Should I Book Central Heating Repair or Boiler Repair? Choosing the right service when the symptoms overlap +
QUICK ANSWER

Choose boiler repair when the problem clearly relates to the boiler itself, such as fault codes, lockouts or no hot water. Central heating repair is more appropriate for radiator, circulation, heating-zone, control or wider system faults.

Central heating repair may suit

  • Cold or uneven radiators
  • Heating circulation problems
  • Heating zones not working
  • Thermostat or controls faults
  • Heating-system leaks

Boiler repair may suit

  • Boiler fault codes
  • Repeated boiler lockout
  • No hot water
  • Boiler ignition problems
  • Water leaking directly from the boiler
BOILER-SPECIFIC FAULT?Problem appears to be inside the boiler?
