Central Heating Upgrades Across Bedfordshire, Hertfordshire, Buckinghamshire and North London

Upgrade your central heating to be more efficient, controllable and cheaper to run. Our heating engineers modernise heating systems across Bedfordshire, Hertfordshire, Buckinghamshire and North London.

Central Heating Upgrades We Offer

Modernise your heating to save energy, improve comfort and reduce bills.

Smart Heating Controls

Installation of Hive, Nest, Tado or similar smart thermostats. Control your heating from your phone, set schedules and use geofencing to heat your home only when you need it. Can reduce heating bills by up to 30%.

Radiator Upgrades

Replace old single panel radiators with modern double panel convector radiators. New radiators heat rooms faster and more evenly. We size each radiator correctly for its room.

System Conversion

Convert from a vented heating system with loft tanks to a sealed pressurised system. Better pressure, no loft tanks, fewer leaks and quieter operation. We install the expansion vessel and fill loop.

Zoned Heating Controls

Split your heating into zones so you can heat different parts of the home independently. Bedrooms warm in the morning, living areas in the evening. Saves energy by not heating empty rooms.

Thermostatic Radiator Valves

Fit or upgrade thermostatic radiator valves on every radiator. Set each room to its own temperature. Modern TRVs are more accurate and reliable than older types.

Pipework Upgrade

Replace old imperial copper or failing microbore plastic pipe with modern 15mm copper or barrier plastic pipe. Improves flow rates and eliminates leaks from ageing pipework.

Central Heating Upgrade FAQs

Common questions about central heating upgrades

Are smart heating controls worth it?

Yes. Smart controls like Hive, Nest and Tado typically pay for themselves within two years through lower energy bills. They let you heat only when needed, learn your routine and can be controlled from your phone anywhere.

How much can I save by upgrading radiators?

Modern double panel convector radiators heat rooms faster than old single panel radiators so your boiler runs for shorter periods. Combined with thermostatic radiator valves you can save 10-15% on heating bills.

What is the benefit of a sealed heating system?

Sealed pressurised systems have no loft tanks so there is less risk of leaks, no tank freezing risk, better hot water pressure and quieter operation. Most modern boilers work best on a sealed system.

Can you upgrade my heating without replacing the boiler?

Yes. We can upgrade radiators, controls, pipework and convert to a sealed system while keeping your existing boiler if it is in good condition. We will advise if the boiler is worth keeping.

How disruptive is a heating upgrade?

Upgrading controls and radiators causes minimal disruption and is usually completed in a day. Pipework replacement is more involved. We protect your floors and furniture and clean up thoroughly.

Do I need thermostatic radiator valves on every radiator?

Building Regulations require thermostatic radiator valves on all radiators except the one in the room with the main thermostat. They give individual room temperature control and improve efficiency.
