Tariq... Unfortunately your plumbing works are not quotable over the internet, you will need a quotation in person from your chosen local plumber. I can say that due to the pipework being in concrete or screed, the Plumbing for the new radiator would be complicated, if your option is to move the pipes in the concrete or screed. It may be the case that the pipework runs underneath the floor, but I very much doubt it due to the type of property that you live in I hope this helps! J Ireland Plumber
