Hi, I’d like to have some quick rewiring done under my boiler.
Currently, I have a thermostat which is attached to my wall and this is connected directly to the boiler’s wiring junction box (it’s not wireless). See: https://ibb.co/jb5ZD14
Now I have bought a new wireless Honeywell thermostat which comes with a wireless relay. This relay needs to be connected to the boiler instead and then the new thermostat will connect to that relay wirelessly. Here is an image of the Relay that will connect: https://ibb.co/7Xzq32G
The existing old thermostat on my wall probably has a couple of wires feeding into it from the junction box. See my image of the junction box and the two wires which I have identified as being connected to this old thermostat. https://ibb.co/bNNths5
Along with these two wires, you’ll need 3 other wires (Live, Neutral and Earth) which I believe are currently connected from the junction box to a fused spur. See images:

Wires: https://ibb.co/L0LH9ZG
So these 5 wires are needed to hook into the wireless relay.
I have attached an image of the wireless relay and its terminal points. https://ibb.co/7Xzq32G
All in all, I just need that relay connected to my boiler so it works. The whole job should take 20-30 mins.
I'm looking for someone to do it within £30-40.
I'm in Chingford.
Please let me know.
Thanks.
