The house we currently rent was built by a polish company using polish workers and materials. Basically it's a kit house that's sent over. The build quality is excellent but tonight I discovered a leak so had to take off a socket. The wiring is all in European type cable which looks like flex with solid cores. The cpc looks to be the same csa as the lives. The socket backboxes are round plastic with 2 side by side to make a double ( everyone follow?) The db has a SELECT sticker and has been signed off by a contractor. What's everyone's take on this as I have the option to buy the house next year. Obviously it wouldn't be a problem to change the backboxes to metal or fastfix. Would this make any difference to the value and should it be pointed out to who ever comes to value the house (the lower the better for me). The house was built in 2008. Just looking for other people's opinions really.
