Central Heating Installation & Upgrades
PHC Services installs and upgrades central heating systems across the coverage area — from individual radiator replacements to full system overhauls. All work is planned around the specific property type and existing infrastructure.
About Our Central Heating Installation & Upgrades Service
A central heating system that is correctly specified and properly maintained is fundamental to a comfortable and efficient home. PHC Services carries out central heating installation and upgrades across London, with coverage extending into Essex and Hertfordshire — including radiator replacement, pump and valve repair, system rebalancing, and full system upgrades in properties where the original installation is no longer performing adequately. In older Victorian and Edwardian properties, we work carefully around original pipework runs and chimney-flue heat routes. In Essex and Hertfordshire, where the chalk water supply creates consistent limescale loading on heating components, we assess and address scale-related restrictions as part of any significant heating work. For 1930s semi-detached properties across the London fringe and Hertfordshire, system boiler upgrades are among the most common jobs we handle. All central heating work is fully insured.

Yes — we can extend an existing central heating system with additional radiators, provided the boiler has sufficient output capacity. We assess this as part of the job planning and advise on any boiler upgrade that may be needed.
Banging, gurgling, or whistling from a central heating system can indicate airlocks, pump faults, sludge, scale build-up, or a failing valve. Contact PHC Services and we will carry out a diagnostic inspection.
