Thanks all, sticking with gas and spend more times on structure/insulation
I'm also planning on insulating under the ground floor but not going to change the gas central heating.
We have to do some damp proofing, and plan to unblock the vent from the outside as well as sorting out the guttering to ensure the likelihood of damp being a lots lower so we won’t have to worry about damp under the floorboard when insulated.
Converting to electric centre heating from gas centre heating.
Best to leave it now then, we’ll try and insulate the floor without causing further damp.
