I doubt he’s coming back. if you haven’t held back a retention payment, best put efforts into someone else it will be more productive

I doubt the contractor will be interested. you did some work he did some work, if you haven’t paid in full that’s a bit different as you have some leverage

If you have no glycol you should have anti freeze valves. Is there another zone that isn’t getting tiled that can let the heat pump work? Get in writing what the process is for re introducing the heat, how many degree per day over what period might save a lot of grief later… good luck

We are trying to subdivide the installation into smaller safer components to minimise lots of issues. i cant see the drama in a switched fused spur and it doesn’t then get switched off.

IET. Means of isolation should be provided at the origin, for every circuit, for every item of equipment, for every motor, for every supply. all current using equipment requiring control shall be controlled by a switch Me. switched fused spur just makes sense

New central heating is invasive so is a full rewire

Only time I fit fuse non switches spurs would be intruder alarms, fire alarms, equipment in bathrooms, everything else is a switched fused spur. But you are the home owner expert, so find another spark if you aren’t happy
