Under the sale of goods act you have paid for a service and a product, i.e, the fence. It is not satisfactory (they have used old weathered wood by the look of it) and it is not of merchantable quality. Therefore you are entitled to reject the work (fence) and are entitled to a replacement or full refund. The law is quite clear and if they fail to comply with the law you have a right to take them to the small clams court to recover the cost and the full cost of a replacement. Photo's are useful evidence to support your claim.
If they don't replace then also report them to trading standards at your local council.
