Common radiator repairs

Radiator repair covers a range of fixes designed to restore heating performance and stop leaks.

Common jobs include:

• Tightening valves
• Replacing damaged pipework
• Repairing pinholes
• Bleeding air from the system

In some cases, a power flush may be required to clear sludge buildup that prevents radiators from heating evenly.

A qualified plumber or heating engineer can inspect your system, pinpoint the issue, and advise whether a simple repair or a full replacement is the most cost-effective option.

How much does radiator repair cost?

The average radiator repair cost in the UK ranges from £70 to £170, depending on the issue and location.

If your radiator is severely corroded or the system is heavily sludged, your engineer might suggest a replacement radiator or system flush, which will increase the cost.

As a guide:

• Minor valve tightening or spindle leaks: from £70
• Replacement radiator valves: around £100
• Corrosion or pinhole leak repair: between £120–£170
• Removing up to six radiators and flushing the system might cost around £350

Radiator repair vs replacement

Sometimes, repairing your radiator isn’t the most cost-effective solution — especially if the unit is old or showing signs of extensive corrosion. As a general rule:

• Repair your radiator if the issue is localised — e.g., a leaking valve, trapped air, or a pinhole in otherwise sound metal
• Replace your radiator if it’s rusting, inefficient, or over 15 years old, as it may continue to develop new leaks and drive up your energy bills

A new radiator installation can also improve heating performance and energy efficiency.

The average cost to replace a radiator starts from around £200–£300, depending on the size and type.

If you’re unsure which option is right for you, ask a heating engineer to assess your system. They can advise whether a simple repair, power flush, or full replacement will deliver the best long-term value.

How long do radiator repairs take?

Most radiator repairs take under an hour for minor issues such as leaks or airlocks. More complex jobs, like replacing a radiator or flushing the system, can take several hours.

A checked radiator repair service will ensure your heating system is properly rebalanced and safe to use once the repair is complete.

Maintenance tips for your radiators

To prevent future radiator problems:

• Bleed radiators regularly to remove trapped air
• Inspect for leaks or rust spots at least once a year
• Avoid ignoring cold spots, as they often signal sludge buildup
• Book annual boiler servicing, which includes system checks and helps keep your radiators working efficiently
