Retrofit Underfloor Heating 2024

Hi, does anyone here have any experience or a recommendation for a company to install retrofit underfloor heating?
We are building an extension and want to get the rest of the house done as well. The existing floors are concrete.
Looking at getting a company to dig out the existing concrete floors. Have a couple of quotes but prices seem dramatically different which makes me nervous…

No recommendations sorry, but if you can provide the number of rooms, area and quotes somebody might be able to say if it seems reasonable or not.

Thanks Zenith63
It’s 160 sqm over 9 rooms. So we need 2 manifolds.
The quotes are €13k and €9k

What’s included in those prices, just break out the old floor and leave it ready for insulating, UFH and screed?
