I found a quote so far and woud like to know if it is good. based on estimated floor plan. I expect the kitchen to be smaller after draws are fitted.

So that's for supplying the materials?

So you need to find an installer happy to fit materials you've bought. That going to be a nightmare if there's a problem later on. You still have the issue of the builder allowing them onsite and laying the sub froor to the correct specifications. You'll also have the cost to screed the downstairs after it's been installed.

Yes

I agree this is not exactly what i want. i actually am looking for someone that will do everything for me. most of these online sites just provide parts and design plans

Speak to the builder to see if they'll allow it then some local plumbers for a price.

So they haven't undertaken any heat loss calculations to determine what you actually need, and haven't taken into account what floor finish you are installing (and therefore what maximum water temperature can be used within the underfloor system - I can guarantee that you won't be able to run at 55 degrees Celsius.

If you're then removing floor area for kitchen cupboards etc, then you need to assess whether the underfloor htg can actually provide sufficient heat output, or whether additional radiators etc are needed anyway.

Too many suppliers/installers use generic figures that don't reflect the actual room.

So i have found developer will provide no access to anyone until completion
I still have not found anyone that can do it all. They told me without flooring the ground floor will be all concrete.

Can installer not dig the concrete to make space for the plumbing so floor level wont increase. Also the kitchen will be installed with cupboards, would thy need to take them all off to install plumbing in kitchen?

I was thinking to get flooring done for only for staircase and bedrooms and hallways upstairs for now.

You want an installer to dig up the concrete :rotfl::rotfl::rotfl::rotfl:

If you are buying a new build, things like UFH should have been specified before construction began. Adding it as an afterthought is a recipe for disaster.

You want to look for 'retrofit underfloor heating'

There are companies that effectively rout the concrete screed, like https://www.jk-gb.com/jk-in-ground-ufh.php , and there other low build-up ones, but I can't see the point on an already finished house. There will be some serious knock-on effects to the finish that will incur additional costs.

Radiators are designed to do the job pretty well, UFH isn't so superior and there's a wide choice of rads if you're inclined to make a feature of them, but no developer is going to warranty any heating system that's been tampered with.

Thanks alot thats exactly what i need. Is that retrofit company good?

The developer providing cheap single rads and boiler. I would probably upgrade the boiler to provide better water pressure

Upgrade the boiler to what?
