Order of work for electrics, new kitchen and bathroom, carpets, replace heating system, painting and replacing doors and windows

Hi Pallavi_51, Get your electrics checked first. Use the results to get quotes for the update though rewire may be quickest and easiest route depending on age condition etc. Get plumber in to give you best boiler position, decide where you want it, discuss radiator positions. Confirm these. Get quotes to your confirmed positions. Confirm your kitchen/bathroom layout. Get quotes for new windows. Get electrician to quote knowing your plumbing "areas" and kitchen/bathroom layout. Decide on who to use. Get all your "messy" trades in, plumbing, electrical first fix, windows and builder to do cloakroom. May need plasterer to finish. Bring carpenters in, fit kitchen, fit bathroom, 2nd fix electrics. Bring in painters Bring in carpets. You will need to project manage a number of trades making sure they all do what they need to when they need to otherwise project will fail. Alternatively use a reputable builder to do everything, he will project manage and you only have to deal with one contact, he gets the headaches! Hope this helps

The answer above is pretty much spot on. The only thing I'd add was once you have positioned the rads or anything else that sits close to the wall I'd get a mist coat followed by 1 x full coat of finish paint behind where these items will go. You could get the painters in to do this or do it yourself. This will save quite a bit of time and awkward masking when the decorations are to be done. Any medium pile roller should be fine, just make sure its rolled out well with no lines or heavy roller marks. The decorator will only need to give those awkward areas one more coat and if the pre-fitting coat was solid this may be all accessible with just a rad roller and thin mohair sleeve.
