Report I've Been Approached To Build An Electricity Substation Beside House in House prices and the economy Posted April 9, 2014 I would be grateful if you would give some opinion on whether an electricity substation beside your house, for example at distances of 5m, 15m and 25m, would affect your wellbeing and in knock on influence the value of your home. I'm ex ScottishPower corporate office. What you are suggesting carries some risk. Not all transformers blow up but when they do... http://www.bbc.co.uk/news/uk-england-essex-20915663 And then you have the electric & magnetic fields issue (which even if you don't believe in, plenty of other people do) as well as the reduction in property value due to visual impact etc. How big a unit are they looking to put in? What voltage? I don't think I'd want a substation anywhere near me personally. If the power company have no alternative location but your yard, you could offer to sell them the whole property at say 150% market value.
