tado Radiator X Quattro Pack review
tado Smart Radiator Thermostat X Quattro Pack
By Tom Calder
We no longer recommend this model, so it no longer appears in our buying guides. In its place, we now recommend tado° Smart Radiator Thermostat X — Trio Pack in our Radiator & heating efficiency guide.
Key specs
The maker's figures.
- What it is
- 4x smart radiator valves (tado X range)
- How it works
- Requires a tado Bridge X or compatible Thread
- Fits
- M30x1.5mm valve thread
- Install effort
- Tool-free DIY swap onto the existing valve body
A tool-free way to put smart control on four radiators at once — it swaps straight onto the existing valve with no plumber and no draining the system. Just budget for the Bridge X hub separately: it's a TRV-only pack, and tado's app control needs a hub to talk to.
- Best for
- Homes with several radiators wanting whole-house smart heating control in one purchase, on tado's current X platform.
- Skip it if
- You don't already have a tado Bridge X or compatible Thread router

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Rechargeable battery via USB-C, no disposable AA cells to keep replacing
- Screws onto the existing valve body — no plumber or drained system required
- Matter/Thread support, so it fits wider smart-home setups, not just tado's own app
Worth knowing
- Bridge X (or another Thread border router) is sold separately and adds £59.99 if you don't already own one
- Geofencing, adaptive scheduling and energy reports sit behind the £3.99/month AI Assist subscription

Who shouldn't buy this
Don't buy this pack on its own if you don't already have a tado Bridge X or compatible Thread router — without one it won't connect to the app at all, and the real all-in cost rises once you add one. Check tado's bundled starter kits first if this is your first tado purchase.
This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the UK price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.
