What should i get done first

PoGee

My house needs an awful lot done. I've had the roof and windows replaced. The next will be CH, electrics, flat roof replacement + velux window, changing back large window (not been replaced yet) to patio/ french doors, WC under stairs, new front and back doors.

What should get done first - electrics or CH? Do I need planning permission to change window to french doors? We're based in West of Scotland.

Both will probably need floorboards lifted, but I'd go with the electrics first. If you are relocating the boiler, make sure that there is a fused switch next to the planned location. Also get an earth cable put in from the consumer unit to where ever the gas pipe enters the house (needs to be 10mm²). Once the electrics have been done, patch the walls to hide the chases plus damage around the switches & sockets (you are going for flush mounted sockets & switches aren't you).

When you get to do the central heating, bear in mind that in a well insulated & draught free property, there is no real need to stick the radiators under windows. So site the radiators in each room where you want them, and aim to keep pipe runs as short as possible. Use 22mm for as much of the flow & return as you can, fit larger radiators than the heat loss calculators suggest - This will enable you to run at lower flow temperatures which helps to push the boiler further in to condensing mode and improves the efficiency (assuming you are fitting a gas boiler).

Fitting oversized radiators and using bigger pipes puts you in a better position when heat pumps are the only replacement option - Worth planning the CH layout with an eye to the future.

Many thanks FreeBear.

I'm confused about the Scottish Government website re building warrants for additional WC facilities. The first part comes under 'allowable without warrant' but the 2nd is 'except'. Why is it allowed without a warrant but in the same breath, needs a warrant? Can someone explain this as I can't understand it?
