Within primary retail frontages (as shown on the Proposals Map), changes of use at ground floor level from use class A1 (Shops) to other uses will not be permitted if the town centre’s vitality and viability will be harmed, or where:

1. The combined proportion of class A1 use and vacant units would fall below 75%; or
2. The proposed use would result in three or more adjacent non-retail uses; or
3. The number, frontage lengths and distribution of non-A1 uses would result in an over concentration of uses detracting from its established retail character; or
4. The proposed use does not fall within use class A2 (Financial and Professional), class A3 (Restaurants and Cafes), class A4 (Drinking Establishments) or class A5 (Hot Food Takeaways).
