I kept it on for over an hour to determine whether or not it was the delay of the app/thermostat. Neither can turn the boiler off on command
Hive thermostat installation

The Hive receiver is only a switch. It simply connects and disconnects the two wires on terminals one and three.
You could try removing the receiver once the boiler has turned on (be careful, as the contacts on the backplate will be live).
If the boiler turns off (after a short overrun), the Hive/receiver may be at fault. If the boiler still doesn't turn off, the problem could be with your boiler/wiring.

Yep, sounds more like a boiler/thermostat/wiring issue, than just the app.
When I turn the switch on, with the wired settings I've attached, the boiler starts up automatically and stays on. Whatever I do on the app/thermostat it won't turn the boiler off, but I'm convinced i can't be the wiring if you guys suggest it's ok.
I'm using a Biasi combi boiler and the hive receiver is a Dual Channel receiver wiring, not sure what else to do from here

That would explain it.
Why do you have a dual channel Hive, when your original controller was single channel and you have a combi?
You've also added an unnecessary link between L and 1.
Ps. Single channel Hive was mentioned in post#2!
Note to self, always ask if the Hive is single or dual channel...

Yep, this time assume did make an ass of u and me!
Actually when I bought it there was no mention of single or double it was just...hive thermostatThat would explain it.

Ok I've done what you said and attached a photo of the new setup, this will still work on a combi boiler with a dual channel?

Leave blue out of terminal 1 and safely isolate in a connector block, move brown in terminal 3 to terminal 4 and see how you get on.

No, I mean one of these: https://www.toolstation.com/connect...VCdrtCh2SKQ0JEAQYAiABEgIp2PD_BwE&gclsrc=aw.ds - called other names too.
The one you wanted would have been named Hive Heating, or some call it Hive for Combi.
Your previous thermostat had volt free switching.
This meant that when there was a call to heat, it simply connected together the blue and brown wires.
The dual channel Hive works differently, it connects the terminals directly to Live.
You may have been very lucky. Some boilers use 24V switching - sending live down the cable, as you have done, could have killed the PCB.
As your boiler is still operating, it will probably be mains switching anyway.
As @CBW has said above, safely isolate one of the cables and connect the other to terminal 4.
As your heating was constantly on before, I suspect you need to connect the blue wire to terminal 4.
