As far as we know, the prices for UK design patents are really low. This kind of IP right can be turned into a great moneymaker. Therefore, the initial investment is justified. Also, generally, it is a good strategy to invest in intellectual property. Moreover, the cost of a UK design  patent is much lower than the cost of a European design patent (RCD). Hence, if you have business in the UK, for example if you are an Amazon seller, then a UK registration may be cheap and sufficient. On the other side, if you have business in EU Member States, you should consider filling an EU design patent.
