Central Heating – We cover all aspects of your central heating from complete installs to replacing radiators. This also includes installation of under floor heating.

Powerflushing – We offer a full power flush to remove limescale and sludge, which will enhance the performance and efficiency of your central heating system.

We install filters to treat water in the heating system and fill with inhibitors so your system performs more efficiently and lasts much longer minimizing the impact on your boiler while increasing it’s life span.

If you are looking to treat your heating system, service it or change the old valves to new thermostatic valves we would be delighted to help.


Whether your boiler needs servicing, repairing or you want to upgrade it we will be happy to help. A qualified and experienced Gas Safe engineer will asses, estimate and install a boiler of your choice.

You can supply any boiler or discuss alternative options and be advised accordingly regarding the make and model that will suit your needs and expectations. New boilers can be mounted on the same wall and be positioned as your old one in case of boiler replacement or any other suitable wall after confirmation with us.

All necessary Gas Safety tests will be carried out and a Gas Safe Certificate will be provided.

Heating Upgrades

At Heating Principles we will concentrate on those heating upgrades where you will see the sustained returns in years to come, keeping your home warm and efficient, as well as keeping the running costs down.

  • Thermostatic radiator valves – this regulates flow of hot water to your radiators and keeps your room at a temperature you desire.
  • Radiators – if you have old radiators, replacing them for new and much more efficient ones would benefit you and your home immensely.
  • Power flush – removing sludge and preventing corrosion will enable the system to run more efficiently.
  • Magnetic system filtration – filter fitted onto your central heating pipework provides an extra protection to your central heating system from build up and corrosion.
  • Insulation – depending on your budget, systematically installed insulation will simply reduce draft which will save you money on your energy bills.
