Understanding Fence Panel Sizes and Spacing
Standard UK fence panels are 1.83 metres (6 feet) wide. Posts are spaced at 1.83-metre centres to match, meaning you always need one more post than the number of panels. Panels come in heights of 0.9, 1.2, 1.5 and 1.8 metres. For boundary fencing, 1.8 metres (6 feet) is the maximum height permitted without planning permission in most cases, provided the fence is not adjacent to a highway, where the limit drops to 1 metre.
Concrete fence posts and gravel boards are popular for their longevity, removing the risk of rot at ground level that affects timber posts. Timber posts should be treated with a suitable preservative and set in postcrete or concrete to a depth of at least 600 millimetres for stability. In exposed or windy locations, deeper post holes and stronger fixings may be necessary.
Choosing the Right Fence Type
Lap panel fencing is the most common and affordable option in the UK, offering a solid screen for privacy. Close-board (featheredge) fencing is sturdier and allows individual boards to be replaced if damaged, making it a better long-term investment. Picket fencing suits front gardens where a lower, decorative boundary is appropriate. Trellis panels work well as extensions on top of solid panels or as standalone screens for climbing plants.
The cost of garden fencing varies widely depending on materials and style. Budget lap panels start from around 20 pounds each, while premium close-board panels can cost 40 to 60 pounds. Posts range from 8 to 30 pounds depending on whether they are timber, concrete or slotted. Labour for professional installation typically adds 30 to 50 pounds per panel on top of materials.
Fence Maintenance and Legal Considerations
Treat timber fences annually with a fence paint, stain or preservative to extend their lifespan. Check for loose panels or leaning posts after storms and repair promptly to prevent further damage. Legally, you are generally responsible for fences on your side of the boundary, though title deeds may specify otherwise. Always discuss fence plans with neighbours before starting work, as boundary disputes are one of the most common causes of neighbour disagreements.
