Likewise, it is not a priority for me until it gets too warm and the boss reminds me that I told her ‘a heat pump can do cooling as well you know’. I want to try it with the UFH so don’t need to do any plumbing. Just need the confidence to play around with the settings, guess I am unlikely to break it or change anything which isn’t reversible …
We get through one bulk bag a month, bought four bags last summer @ £90 each. I used to get most firewood free from work and neighbouring woodland but only getting a few scraps now.
Same here, they did ask if there was any major structural work. We declared decorating, landscaping etc. and made sure it was confirmed in writing. (We didn’t have or ask for any BC documentation)
Building control visits are normally focused on checking as-built versus approved plans so they can look at any details, ie. level thresholds, smoke detectors, escape windows etc, etc. They wouldn’t have time to look through documents but for final submission, I would add; SE calcs/drawing, roof truss calcs, any MCS certs, Gas Safe certs, planning approvals, window and door specs …
I used a local branch of national chain, handy to get additional supplies as the installation progresses and take back what you don’t use. I mail ordered a lot of other stuff but electrical components need to be available to avoid holding up electrician, or losing him to another job. Do check prices are reasonably competitive but availability is sometimes more important.
My experience was that neither planning or building control check or seem to care about this. I have a gravel drive but large patio at the back was supposed to be ‘permeable surface’. I laid sandstone slabs which slope away from the house to the lawn, so I would argue that all rainwater soaks away on site. If your drive is impervious and slopes to a road, someone may challenge it.
Why do you want to move the bathroom to a corner, will need a corridor and take up window space on the front and rear aspects. Bathrooms are in the best place IMO, create a utility in the back of the garage.
