Fence Post Replacement Cost UK: 2026 Pricing Guide

Fence post replacement in the UK costs £15-£60 per post depending on material. Timber posts cost £15-£30, concrete posts £25-£45, and metal posts £30-£60. Professional installation adds £20-£40 per post. A typical garden with 6-8 posts costs £120-£400 for DIY, £250-£700 professionally.

Concrete fence posts are best for UK weather—they never rot and last 25+ years despite rain and frost. Pressure-treated timber is second best (15-20 years). Avoid untreated softwood, which rots within 5-10 years in the UK's wet climate.

Yes, DIY fence post replacement costs £15-£30 per post (materials only). You'll need a post hole borer, level, and postcrete. Allow 2-3 hours per post including concrete setting time. The hardest part is removing the old concrete footing—use a sledgehammer and digging bar.

Fence posts in the UK should be set at least 600mm (2ft) deep—deeper for exposed sites or taller fences. The hole should be 300mm (1ft) wide. Use postcrete or dry packed concrete, allowing 24-48 hours for curing before attaching panels.

Signs your fence posts need replacing: visible rot at ground level (probe with a screwdriver—soft wood means rot), leaning or unstable posts, fungal growth or white rot on the wood, and water damage at the base. Replace posts before the entire fence collapses.

Timber posts are cheaper initially at £15-£30 vs £25-£45 for concrete. However, concrete lasts 25+ years vs 15-20 years for treated timber. Over 25 years, concrete is actually cheaper—1 set of concrete posts vs 1-2 sets of timber.
