Insulation

Insulating a victorian home... first time buyers.

Our home is generally comfortable (well by Victorian standards - 17oC room temperature!) with the exception of our main bathroom that is on the first floor above the kitchen. We get terrible draft from under the skirting boards and from a hole cut in the floor boards to install a combi boiler (hole is about 1 foot square and appears to be directly into the ventilated floor - previous owner responsible for this!) and heat is lost through the solid walls. I'm in the process of ripping up some old floor tiles in this room and removing the current Toilet and bath to refub and whilst I'm making a mess anyhow, plan to insulate thoroughly... I wondered whether the following is reasonable; 1 - lift floorboards and install loft insulation in netting between joists 2 - ply over floorboards prior to new floor (amtico or similar) 3 - refit skirting boards ensuring a good fit ? Once the boards are lifted, will I be looking at the top of the ceiling of the room below? In which case is this an opportunity to insulate there too? Now, as I want to do a thorough job, I'm considering adding kingspan or cellutext to the walls. The question is, would you lay this over the existing plaster or knock back to brick first? Should I also take the ceiling down and insulate under it? I'm very new to this but the plaster on the wall sounds hollow - as though a gap is present, as does the ceiling - looking at thr pitch of the roof it looks like there could be a huge amount of space above the current ceiling. Many thanks for your assistance. D
