With temperatures expected to hit 31C this week, many green-fingered people will be making the most of their outdoor spaces, but some may find themselves accidentally breaking the laws.

From growing Japanese Knotweed to installing tall hedges, it’s important to be aware of potential landscaping breaches as they could cost you a whopping £5,000. Anna McEntee, of Compare the Market, has urged homeowners to check regulations before carrying out work or contact their local planning authority.




To help residents stay on the right side of the law and avoid major fines this summer, Anna has revealed the most “common” garden-related violations and their potential penalties.

Growing Japanese Knotweed

Good: Up to £5,000 and a possible prison sentence of up to two years

Regulation: The Wildlife and Countryside Act 1981

Japanese Knotweed is a fast-growing invasive plant that is notoriously difficult to eradicate compared to other species. Under the Wildlife and Countryside Act, it is an offense to plant Japanese Knotweed or allow it to grow in the wild. While it is not illegal to have the plant on private property, residents can face fines of up to £5,000 if they allow it to spread in natural areas.

According to Natural Resources Wales, this may include “cutting, shaking or throwing away” contaminated material, which could be a criminal offence. If any transfer of waste leads to the spread of Japanese Knotweed in the wild, UK residents could face a prison sentence of up to two years.

High hedges and fences
