London: Re-route central heating pipes underneath wooden floorboards (ended)

Re-route central heating pipes underneath wooden floorboards

Looking to get an idea of costs to re-route existing ugly pipework to 5 radiators across 5 rooms in a first floor Victorian purpose built maisonette. The pipes currently run above the skirting board and through the wall between the rooms, in 2 of the rooms they are routed through the ceiling/loft. In addition 2 of these radiators will need to be repositioned to different walls - very close to existing position. Please see attached floorplan for more info. This property is at the beginning stages of renovation and so is empty, wooden floorboards are exposed and so easily accessible. Many thanks
