Can't remember off the top of my head mate, think it was about 2300
Nigh on full replumb of the entire house, removal of the old Baxi and storage tanks, installation of new boiler, all new rads. Boiler was also resituated to an upstairs back bedroom rather than where the baxu was.
Added 3 new rads, went with the WB 30 CDi a rather expensive WB wireless stat and proper Drayton TRV's, TF1 filter and a full chemical flush.
All done within 3 days, really happy with the job, their pipe routing left a little to be desired tho so we redid the piping in a more efficient manner, and despite using speedfit still covered all piping in insulation.
