Heating System Upgrade

What a heating system upgrade can improve

A heating system upgrade targets the distribution side of your central heating, helping your system run cleaner, quieter and more evenly.

• Improve heat distribution so rooms warm up more consistently
• Reduce cold spots, noisy radiators and slow warm-up times
• Optimise pump and system settings for efficiency and reliability
• Replace or upgrade faulty radiators, TRVs, lockshield valves and zone valves
• Diagnose circulation issues, air ingress and pressure-related faults
• Upgrade controls to improve scheduling and temperature control
• Powerflush or clean the system where sludge and debris are affecting performance
• Balance radiators to support even heat across the property

When a heating system upgrade makes sense

This service is a good fit if your boiler works but heating performance is poor. It is also useful after extensions, radiator changes, recurring callouts, or if some rooms never feel warm enough. Landlords and small commercial sites often choose upgrades to improve reliability and reduce tenant or staff complaints.

What’s involved

Work starts with checks to understand how the system is currently operating, then a clear plan of recommended improvements.

1. Assessment and fault finding: radiator temperatures, pressure behaviour, pump performance, controls, and signs of sludge or air.
2. Recommendations and fixed scope: what will be adjusted, repaired, cleaned or replaced, with clear outcomes.
3. Upgrade works: repairs, part replacements, balancing, control improvements, and cleaning where needed.
4. Testing and commissioning: verify heat distribution, hot spots, noises, and correct control operation.

Timing depends on the issues found and the amount of work required, but most upgrades are planned to minimise disruption.

Aftercare and ongoing value

After the upgrade you should see steadier temperatures, fewer symptoms like banging or gurgling, and easier control over heating schedules. Where cleaning work is carried out, you will be advised on best practice to help keep the system protected, such as inhibitor levels and any follow-up checks.
