It is quite common for alterations or extensions undertaken without building regulation approval to cause difficulties when you are selling a house.
This happens when the vendor cannot supply the purchaser with the appropriate approval notice and/or completion certificate. This calls into question the quality of building construction and the structural integrity of the work. A Regularisation application can be submitted for work undertaken after 11th November 1985 which will assist this but you need to be aware that a fee is payable to the Council and breaches to the building regulations may need to be rectified.
