The South Downs National Park Authority has a relevant press release:
Local residents and walkers using footpaths around the South Downs village of Cocking now have a clearer view, thanks to a £25,500 scheme by Southern Electric Power Distribution (SEPD) to remove nearby overhead power lines. .. SEPD engineers have recently completed a three month project to replace overhead electricity lines from land near the church with replacement underground cables. Three spans of power lines have been taken down and four wooden poles. .. The project was funded by a special allowance, granted to SEPD by industry regulator Ofgem, to invest in projects to underground power lines in AONBs and National Parks in central southern England.
