Genuine Myson specialists
We specialise in genuine Myson heating controls and spares — from TRV2 thermostatic radiator valves and manual valves to MPE motorised valves, room thermostats, Kickspace fan convectors and Floortec underfloor heating. Because we focus on authentic, fully warranted parts sourced through official channels — never unbranded copies — the component you fit is the one that's designed for your system and built to last. If you're replacing a like-for-like Myson part, we'll help you identify the exact match.
Thermostatic radiator valves (TRVs)
A thermostatic radiator valve (TRV) automatically controls the temperature of an individual radiator, saving energy by only heating rooms to the level you need. We stock genuine Myson TRV2 thermostatic radiator valves in 10mm and 15mm sizes — including angled, straight and pushfit options — plus complete radiator packs with matched lockshields. New to TRVs? Read our guide on how a TRV works.
Heating controls & thermostats
From simple dial room thermostats to programmable and smart wireless (RF) controls, the right heating control keeps your home comfortable and efficient. Browse our electronic heating controls and thermostats from trusted brands including Myson, Danfoss, Drayton and EPH, with OpenTherm-compatible options for modern combi and system boilers.

Frequently Asked Questions
Are your Myson parts genuine?
Yes. We only supply genuine, fully warranted Myson heating controls, valves and spares sourced through official channels — never unbranded copies.
Do you offer free UK delivery?
Yes, we offer free standard delivery on all in-stock products across mainland UK, with no minimum order.
How quickly are orders dispatched?
In-stock orders placed before 12:00pm (Monday to Friday) are normally dispatched the same working day. Orders placed after this are dispatched the next working day.
Can I order as a trade customer or in bulk?
Absolutely. Installers and merchants can request tailored trade pricing using the 'Request a trade quote' button on any category page, or by contacting us directly.
What if I can't find the product I need?
Send us a message with the product details and we'll do our best to source it and get you a quote — we supply far more than is listed online.
What size TRV or radiator valve do I need — 10mm or 15mm?
Most UK domestic radiators use 15mm valves, while microbore heating systems use 10mm. Check the outside diameter of the copper pipe running to your radiator, or measure the existing valve's compression nut. If you're unsure, send us a photo and we'll help you identify the right size.
What's the difference between compression and pushfit valves?
Compression valves seal onto copper pipe with a brass olive and nut and are the traditional installer's choice. Pushfit valves simply push onto the pipe for a tool-free connection, which is quicker for DIY. Both are reliable when fitted correctly — choose whichever suits your pipework and confidence level.
What is your returns policy?
Unused items can be returned within 30 days in their original condition and packaging (a 20% restocking charge applies to non-faulty returns). Faulty items are covered by the manufacturer's warranty.
