Radiator Valves

Radiator valves are an integral component of the radiator, allowing you to control the heat output so you can manually set the temperature of the room to one that is comfortable for you. They are essentially what connects your new radiator to your central heating system, outwardly.

Radiator valves are an integral component of the radiator, allowing you to control the heat output so you can manually set the temperature of the room to one that is comfortable for you. They are essentially what connects your new radiator to your central heating system, outwardly.

They do not come with the radiator and need to be chosen separately due to the fact that not all pipework is the same, so you need to choose a valve based on how your pipework is set up and the position of the valve inlets on your new radiator. And on your interior décor tastes of course!

Radiator valves are either manual or thermostatic – but then come in a variety of shapes, sizes and finishes. Ensure that you choose one you like the look of, as the valve will be very visible and, in a way, completes the look of your radiator. They always come in a set.

We have a selection of manual, corner, thermostatic and modern valves as well as straight, traditional, square and angled valves. We offer 10 types of finish as well, including stylish chrome, copper, black nickel and pewter.

Radiator Valves FAQs

A radiator valve is responsible for allowing the pressurized water into your radiator. The radiator valve controls the water that flows into your radiator, allowing for the effective and efficient heating of your home. The radiator valve comes in a variety of shapes and sizes, also holding a variety of functions for the different radiators out there.

There are many sizes, styles and materials for radiator valves:

  • Angled Radiator Valves
  • Corner Radiator Valves
  • Manual Radiator Valves
  • Modern Radiator Valves
  • Square Valves
  • Straight Radiator Valves
  • Thermostatic radiator valves (& angled TRV)
  • Traditional Valves
  • Lockshield Valves
  • Depending on the positioning of your plumbing system and radiators, not all with be suitable for you. Please contact us to help choose your perfect radiator valve.

    They are more commonly known as TRVs and their main function is to control the air temperature of a space by automatically adjusting the amount of hot water that enters the radiator. A TRV will allow you to have a little more control over the temperature in the room, creating a warm and inviting space whilst also remaining energy efficient.


    If you set up a TRV in the correct way, it will allow you to create different heating zones throughout your home, despite only having one centralised boiler system providing your main source of heat. We have multiple designs available, such as an angled thermostatic valve and more traditional radiator valves.

    Straight radiator valves don't incorporate any curves or bends. They connect to a radiator or towel rail up from the floor. Angled valves are usually used to provide a clean finish, concealing pipework and plumbing more effectively than their straight counterparts.
