As the UK heads into peak DIY and gardening season, a leading property expert has warned that simple home improvements could land homeowners in legal hot water – or worse, facing fines worth thousands of pounds.
According to Elite realty Invest, many Britons are unaware that certain outdoor changes – from fences and driveways to garden sheds – are regulated by planning laws, local council rules, and even shared ownership agreements.
Founder Darren Gallagher says: “Summer is when people tackle home upgrades, but not everything is as simple as heading to B&Q and getting stuck in. If you live in a conservation area, near a public road, or even in a semi-detached home, there are rules in place that could trip you up.”
Common outdoor mistakes that could lead to legal trouble or fines:
Installing the wrong type of fence
Fences over 1 metre high next to a highway or over 2 metres elsewhere often require planning permission. In conservation areas, even replacing an existing fence can need approval.
Building a shed, summerhouse or outbuilding without checking regulations
These can fall under permitted development – but not always. Restrictions apply to size, height, and proximity to boundaries.
Paving over your front garden
Replacing grass or soil with non-permeable paving over 5 square metres requires planning permission to prevent localised flooding.
Cutting down trees without checking TPOs (Tree Preservation Orders)
Removing or pruning a tree with a TPO, or in a conservation area, without permission can result in a fine of up to £20,000.
Installing a new driveway without drainage
Driveways using impermeable materials like tarmac or concrete, without appropriate drainage, can also require planning permission.
Misplacing your fence or boundary line
Erecting a fence on a shared or neighbour’s boundary can cause legal disputes under the Party Wall Act.
Gallagher concludes: “What seems like a small job can quickly escalate if you haven’t done your checks. We always recommend homeowners speak to their local council’s planning department or consult their title deeds before starting outdoor projects.”
He says homeowners – particularly those in conservation zones or with listed buildings – should be cautious and ensure they have the right permissions before starting any structural garden or exterior changes this summer.
