Heating control

Hi, im looking to run HA as a vm on my proxmox box. But ive decided not to do lighting at this time (doing a refurb so gonna recable) but want to have per room heating control. I plan to use rf trv’s, but id like a mix of trv’s with temp sensors combined and separating these. I also have some electric heating I want to call based on room temperature.
Im unsure of what to have. Obviously budget isn’t unlimited but I want something that is reliable and has 2 way comms.
Im UK based.
There are other things I want to add to I have 3 areas I want surround sound in and tv control but I thought id start with heating as im not buying the AV stuff till later in the spring.
Many Thanks for any suggestions

James
