Aqara Radiator Thermostat, Floor Heating and Water Valve Installation in London

• It screws straight onto M30 x 1.5 valve bodies, and six adapters in the box cover RA, RAV, RAVL, Caleffi, Giacomini and M28 x 1.5 valves
• Two AA batteries last up to two heating seasons, on Aqara's estimate
• In Thread mode it joins Matter apps; schedules, frost protection, an external sensor and the W100 link need Zigbee mode in the Aqara Home app, with an Aqara hub
• Open-window detection needs a door and window sensor on that window

• A smart head screwed onto a thermostatic valve that is already there leaves the water sealed in, and involves neither gas work nor electrical installation work
• A radiator with a plain manual valve needs a thermostatic valve body first, which usually means draining down and refilling the system; the HSE allows that wet work without Gas Safe registration, but it is plumbing and booked separately
• A valve that no adapter in the box fits needs a third-party adapter or a new valve body
• A valve that leaks, is seized or is corroded is flagged from your photos rather than forced

• Swapping an existing thermostat on the same circuit is a replacement and not notifiable, once the pro has checked that the circuit, fuse and RCD suit the heating load
• Aqara gives 86 x 86 x 45 mm as its overall size but no depth inside the wall, so the back box is checked from your photos
• JACK books no fixed electrical work inside bathroom zones, so for a bathroom or en-suite floor, show where the thermostat sits in relation to the bath or shower
• A brand-new 16 A circuit for the heating is for a registered electrician; JACK does not book it
• The battery-powered W100 Climate Sensor, a temperature and humidity display, can control the W500 or W600 in Zigbee mode

• Aqara's UK shop suggests the Dual Relay Module T2 can control a boiler that accepts dry contacts, but that connection is made at the boiler
• Gas Safe Register's guidance says a boiler case held on by several screws is normally part of the sealed combustion system and should only be opened by a Gas Safe engineer; as its own rule, JACK sends any wiring at the boiler itself to a Gas Safe registered engineer
• Replacing an old programmer or room thermostat at the wall is not gas work under the HSE's code of practice, and heating controls built for UK boilers, such as Hive or tado°, do that job; JACK pros fit both

• Aqara lists it for lever or butterfly-handle valves on DN15, DN20 and DN25 pipes, on four AA batteries lasting up to 2 years, with a compatible Aqara Zigbee hub
• Paired with Aqara water leak sensors, such as the Water Leak Sensor T1, which its Amazon UK listing suggests placing under sinks and near boilers, it can close the valve automatically
• Aqara's UK shop markets it for water and gas valves; JACK fits it on water valves only and never on a gas valve, whatever the listing says
• The handle has to be a lever or butterfly type, so send a photo of the valve itself

A vetted pro prices your Aqara job from the models and your photos, and the JACK app shows that fixed price before you book.

What the job touches moves the price more than the device does. Pairing a hub, fixing sensors, clipping a Curtain Driver E1 onto a rail or fitting radiator thermostat heads is set-up work. A smart lock is locksmith work on the door. An H1 or H2 switch, a Dual Relay Module T2 or a 230 V blind motor is mains work on an existing circuit, priced for isolating, connecting and testing.

The home comes next: a multipoint door that needs adjusting before a lock goes on, a bell transformer too weak for the doorbell, a PoE cable through solid brick. Where a job needs a second pair of hands, your pro can ask another pro on JACK to help through the Pro2Pro feature. Several devices, Aqara or other brands, go on one booking for one fixed price.

You buy the Aqara products; JACK does not sell them. Accessories the job needs, such as a replacement cylinder, a deeper back box, a 12 V plug-in supply or a PoE injector, are agreed and added at cost before you book, and so is parking where it has to be paid for. Prefer to pay for time? As a guide, hourly hire is typically £45–£95 per hour for smart home work, £55–£110 for electrical work and £60–£130 for locksmith work, and a full-day handyman booking is a flat £350–£400 for up to 8 hours on site.
