Materials, methods & variations
Everything you should know before commissioning the work.
Fencing specification is more involved than it appears. The blocks below cover the variables that determine a 5-year versus 20-year fence - and where most installs cut the corner that costs the homeowner.
Post types and specification
Concrete slotted posts: 50-year life, support timber panels, cost 30–40% more upfront but eliminate post-rot failure mode. Pressure-treated timber posts (UC4 grade, 100x100mm minimum): 15–20-year life, traditional appearance. Metal posts (e.g. DuraPost): galvanised steel, 25-year life, modern aesthetic, expensive.
Panel styles
Closeboard (vertical featheredge) - strongest, most private, traditional Cotswold style. Hit-and-miss - 50% airflow, ideal for high-wind sites, modern look. Slatted (horizontal or vertical) - contemporary, semi-transparent. Lap panels - budget option, 8–10 year typical life, rarely recommended.
Heights and planning
Up to 2m: permitted development on most domestic boundaries. Adjacent to highway: 1m maximum without planning. Conservation areas and listed buildings: often require consent - we flag at quote stage. Trellis or post extensions can take effective screening to 2.5m+ without planning in many cases.
Gravel boards
Concrete gravel boards: prevent timber-to-ground contact, eliminate the primary rot path, 25-year life. Timber gravel boards: cheaper, replaceable, 8–10 year life. We specify concrete as standard on closeboard fences - the cost difference pays back inside the first replacement cycle.
Fixings and treatment
All fixings galvanised or stainless - bright steel is incompatible with pressure-treated timber. Timber: UC4 graded pressure-treated to BS 8417, minimum 12-year warranty. Cut ends sealed with end-grain preservative on every cut.
Gates and ironmongery
Field gates, pedestrian gates, double gates, automated gates - each requires hung-and-latched correctly with rated hardware. Drop bolts, slam locks, automated openers (Came, Nice, BFT) coordinated with electrical first-fix during the build.
