Hive Single Channel Receiver Installation in London
Updated
Hive's single channel receiver is the one for combi boilers and for extra heating zones. It runs on mains power and switches the boiler's call for heat, mains or low voltage, when the thermostat asks. A vetted JACK pro fits or replaces it where your old controls were, for a fixed price before you book.
In short
Yes. A JACK pro in London fits or replaces Hive's single channel receiver (SLR1) for combi boilers and extra zones, in place of an existing timer, receiver or programmer on the same wiring, then tests the boiler. Hive's guide calls for a switched fused spur with a 3 A fuse. If your combi has never had external controls, the first connection at the boiler needs a Gas Safe engineer.

How the Single Channel Receiver is powered and mounted
Inside, the single channel receiver is a switch with volt-free contacts, which is why Hive says it can switch either a low-voltage or a mains boiler control signal: the voltage being switched comes in on the common terminal. That makes it the flexible choice for combis, whose control inputs vary by make.
Hive's guide wants it near the boiler or central heating controls, at least 30 cm from large metal objects, and clear of buried cables and pipes. On a combi in a kitchen cupboard, that usually means the wall beside the boiler where the old timer or receiver sat.
What the pro checks first
- That the boiler is a combi, or that this receiver is for an extra zone
- Whether the boiler's call for heat is mains or low voltage
- That the old controls connect at the wall, not only inside the boiler
- The fused spur's rating and condition
What the pro does on the Single Channel Receiver
- Supply isolated at the fused spur and proved dead
- Old timer or receiver removed; a stand-off or decoration plate (sold separately) fitted if needed
- Receiver backplate fixed with its terminals at the top, existing wiring connected
- Switch set to the standard relay position for a combi
- Boiler fired and stopped from the receiver's heating button, then paired
Before you book: what to send
- A photo of the boiler label and of the controls next to it
- A photo of the fused spur supplying them
- Whether this receiver is for the main heating or an extra zone
How Hive installation is priced
A vetted pro prices your job from photos of the boiler, your existing controls and the Hive kit, and the JACK app shows you that fixed price before you book.
Full pricing guide for Hive installationFrequently asked questions
Can a single channel receiver control hot water?
No. It has one channel, for heating. A combi heats water on demand, so it does not need one; a boiler with a hot water cylinder needs Hive's dual channel receiver instead.
My Hive receiver has no lights. Is it broken?
Hive's support says no lights usually means the boiler and controls are not getting power, so check the boiler's isolation switch and your fuse board first. If power is there and it is still dark, a pro can test the supply and the receiver.
How much does Hive Single Channel Receiver installation cost in London?
It is a fixed price for your Single Channel Receiver, worked out by a vetted pro from the model, a photo of where it is going and what power is there now, and shown in the JACK app before you book. Other devices can go on the same booking for one price. If you would rather pay for time, hourly hire for smart home is typically £45–£95 per hour as a guide.
