1. At the outset, I appreciate that now you have bought this new house, you believe you have not got what you expected, namely a fully refubished house. Instead there are some problems with it. However, in any house transfer, the latin maxim caveat emptor or buyer beware applies. This means that you bear any risk associated with the house from the moment of sale. Up to the moment of completion, you can require the seller to correct any deficiencies in relation to the house. HOwever, once you have purchased the property, then you bear the risk of anything going wrong with it or of any deficiencies coming to light from that date. So I regret to say that you will bear any of the problems which you have discovered with the house from the date of completion. This includes items, such as the lack of wireless, the leak, the dishwashers, the manhole. From the date of sale, the seller bears no liability to you. It should have been explained to you by your solicitor that once you completed the purchase, there was no going back and holding the seller liable for any defects subsequently discovered.
2. One of the reasons you go a structural survey and valuation survey done was to satisfy yourself that you were happy with the house. Once you took possession of the house upon completion all risk in relation to the house passed to you. The seller no longer bore any liability. I regret to say that this is the case, but it is a lesson to be learned in relation to purchasing any house. Don't complete the sale until you are happy with what you are buying. After completion, it is too late to complain.
