Heads-up: Closeboard (feather-edge) fencing is built on site from posts, rails, gravel boards and individual feather-edge boards — not panels. Expect 3 rails per bay over 1.8 m high. Why it matters: Boundary fences over 2 m need planning permission — even in your own garden.
Underground services check recommended before excavation. Use a CAT scanner or contact utility providers.
Why it matters: Gas, electric, water and telecoms cables are often shallower than expected — HSE guidance HSG47 mandates a safe-digging process.
If ignored: Striking a live service can cause serious injury, supply outages affecting the whole street, and personal liability for repair costs.
