Why Westhill Is Different A planned town, and what that does to its wiring.
Until the early nineteen sixties this was a hamlet in the parish of Skene with fewer than a hundred residents. Then in 1963 an Aberdeen solicitor, Ronald Fraser Dean, put forward a plan for a new town here, backed by the council of the day and the Secretary of State for Scotland and financed by the Ashdale Land and Property Company. The first houses went up in the autumn of 1968.
What happened next is the part that matters to your electrics. The population was around five hundred in 1971 and approaching five thousand by the late seventies, and the town has kept growing in distinct waves ever since, reaching 11,750 by 2022. Aberdeen's oil and gas economy drove it, and Arnhall Business Park and the subsea engineering cluster keep driving it.
So unlike an old granite town that accumulated slowly, Westhill's housing comes in cohorts. Your street was very likely built over a couple of years by one developer to one specification. The wiring went in at the same time, to the same standard, using the same materials. And it ages at the same rate.
