UK homeowners face up to £5,000 fines for fences exceeding height limits without permission.

In the UK, back garden fences can be up to 6.5 feet high and front fences up to 3.3 feet without planning permission. However, higher fences may need approval from local authorities. The new 2015 order simplifies rules but warns homeowners they could face fines up to £5,000 for non-compliance. Regulations vary by location, so consulting local authorities is advised.
