The job
On Monday 2 November we were in Chelmsley Wood, B37, to fit a smart thermostat. The customer had an old two-wire Honeywell thermostat, which you can see in the first photo after we took it off the wall.
The Hive
We fitted a Hive smart thermostat, which we supplied, in place of the old one, and tested it with the heating on Boost. The last photo shows the Hive receiver beside the boiler, with its two green lights on. Our smart thermostats page compares Hive with the other makes we fit.
Set up on the customer’s phone
Before we left, we set up the Hive app on the customer’s phone and explained how to use it, so they can control their heating from the app.

“Excellent service from Saeed installed my Hive smart heating system. He left everything clean and tidy, explained how to use Hive. I would have no hesitation recommending Saeed.”

Common questions
Can a Hive replace an old wired thermostat?
Often, yes. Here the old thermostat was a two-wire Honeywell, and the Hive went in its place. We check the existing wiring and the boiler before fitting, as our smart thermostats page explains.
Do you set up the app?
Yes. On this job we set up the Hive app on the customer’s phone and showed them how to use it before we left.
What does Boost do?
Boost turns the heating on for a set time, whatever the schedule says. In the photo the new thermostat is on Boost, with 43 minutes left, while we tested it.
How much does it cost to fit a smart thermostat?
This Hive was £320, supplied and fitted. Smart thermostats are supplied and fitted from £200, depending on the model. If you already have your own thermostat, fitting it is quoted, typically 1–2 hours.

Rust at the back of the heat exchanger and a carbon monoxide reading on the analyser, in a house with a young family. We capped the boiler off, told the tenant and landlord, and replaced the cracked flue collector and gaskets with the landlord's permission.
Mentioned at the boiler service: one room never got warm enough. The radiator was working, just too small, so we replaced the single-panel radiator with a double.
The customer mentioned the leak and the heating staying on when we arrived for the service. The diverter valve had rust and corrosion around its ports, so a new one went in. Combustion tested clean.
