A finish time earlier than the start counts as a night shift past midnight. Under the Working Time Regulations, average weekly hours should not go over 48 (usually averaged over 17 weeks) unless you have opted out, and adults are entitled to an 11-hour break between working days. Extra hours may be paid as overtime or taken as time off in lieu, depending on your employer.
