01 Why Are My Radiators Hot at the Top but Cold at the Bottom? The radiator heats unevenly and the lower section stays noticeably cooler +
QUICK ANSWER

A radiator that is warm at the top but much cooler at the bottom can be linked to poor circulation, system deposits or another central-heating issue. The wider system may need checking, particularly if several radiators are affected.

The problem may involve

  • Poor system circulation
  • Heating-system deposits
  • Radiator flow problems
  • System balancing
  • Heating-system condition

Useful details to note

  • How many radiators are affected
  • Whether the top gets fully hot
  • Whether heating performance has worsened gradually
  • Current boiler pressure
  • Whether some rooms heat normally
RADIATOR PERFORMANCESeveral radiators heating unevenly?

A heating-system assessment can help identify whether circulation or another system issue is affecting performance.

02 Why Is Upstairs Warm but Downstairs Still Cold? Different parts of the property are heating very unevenly +
QUICK ANSWER

Large temperature differences between floors can involve heating balance, radiator flow, controls, zoning or circulation. The boiler may still be operating normally while the wider central-heating system distributes heat unevenly.

Possible causes

  • Heating-system imbalance
  • Radiator valve problems
  • Circulation issues
  • Heating zones or controls
  • Different room heat requirements

Useful information

  • Which floor heats properly
  • Which radiators remain cold
  • Whether all radiator valves are open normally
  • Whether the problem is recent
  • Whether separate heating zones are fitted
UNEVEN HOME TEMPERATURESOne part of the property staying cold?

Tell us which rooms or floors are affected so the heating-system problem can be assessed.

Arrange Heating Check →
03 Why Are My Heating Pipes Making Banging or Ticking Noises? Noises appear when the heating starts, stops or changes temperature +
QUICK ANSWER

Heating-system noises can have several causes. Pipe expansion, circulation, trapped air, valves or other components may all contribute depending on where and when the noise occurs.

The noise may relate to

  • Pipe expansion and movement
  • Heating circulation
  • Trapped air
  • Radiator or control valves
  • Another system component

Useful information to record

  • Whether it is banging, ticking or gurgling
  • Where the noise is loudest
  • Whether it starts when heating comes on
  • Whether radiators still heat normally
  • Whether boiler pressure changes
NOISY HEATING?Noise becoming persistent?

Tell us where the noise appears and whether it is affecting normal heating performance.

04 Can a Heating Engineer Replace My Thermostat? Your thermostat is unreliable, outdated or no longer controlling the heating correctly +
QUICK ANSWER

A heating engineer can assess heating controls and help determine whether an existing thermostat or related control needs replacement. Compatibility depends on the boiler and current heating-control setup.

You may need help if

  • The thermostat no longer responds
  • Heating comes on unexpectedly
  • The displayed temperature appears inaccurate
  • The receiver loses communication
  • You want updated heating controls

Compatibility can depend on

  • Boiler make and model
  • Existing thermostat
  • Wired or wireless controls
  • Existing heating zones
  • Current control wiring
HEATING CONTROLSThermostat causing problems?

Tell us what controls are currently fitted and how the heating is behaving.

Check Heating Controls →
05 Why Is Water Leaking From a Radiator Valve? Water is appearing around the valve or connection beside a radiator +
QUICK ANSWER

Water around a radiator valve can come from the valve, connection or nearby pipework. Even a small leak can contribute to gradual heating-system pressure loss, so persistent leaks should be checked.

Possible sources

  • Radiator valve
  • Valve connection
  • Radiator connection
  • Nearby heating pipework
  • Another fitting

Useful checks

  • Note exactly where water appears
  • Check whether boiler pressure is falling
  • Keep water away from electrical equipment
  • Do not dismantle heating components yourself
  • Report a worsening leak promptly
HEATING SYSTEM LEAKRadiator valve continuing to leak?

A heating engineer can assess the valve, connection and wider pressure behaviour.

Report Heating Leak →
06 Can My Existing Heating System Be Upgraded? The system works but you want better controls, radiators or performance +
QUICK ANSWER

Existing heating systems can sometimes be improved without replacing everything. Depending on the property, options may include controls, radiator changes or other system alterations. The existing boiler and heating layout should be considered first.

Possible improvements

  • Updated heating controls
  • Radiator changes
  • Radiator valve upgrades
  • Heating-system balancing
  • Wider heating alterations

Before deciding

  • Consider boiler condition
  • Assess current radiator performance
  • Look at existing controls
  • Consider property heat requirements
  • Identify the main problem you want to solve
HEATING IMPROVEMENTWant better heating control or performance?

Tell us what you would like to improve so the existing heating setup can be assessed.

07 What If My Boiler Works but the Heating Does Not? Hot water may still work while the radiators remain cold +
QUICK ANSWER

If hot water works but the central heating does not, the problem may involve controls, circulation, heating zones or part of the boiler’s heating operation. Fault diagnosis can determine whether the issue is boiler-related or within the wider heating system.

Possible causes

  • Thermostat or programmer problem
  • Heating controls fault
  • Circulation issue
  • Heating zone problem
  • Boiler heating-mode fault

Safe checks

  • Check thermostat settings
  • Check the heating programme
  • Check boiler pressure
  • Look for a fault code
  • See whether every radiator is affected
