Cost of gas central heating installed?

[Angela234]

Hi Our estate is having gas installed we have the option to have the mains gas brought to the outside of our house for a cheaper rate as they are doing the whole estate (council estate we have brought ours)
Does anyone know how much it cost to have gas brought into our house and boiler/radiators etc we have a 3 bed house
I just want a rough idea as i have no idea at all.

Thanks for any help
