Birchwood, Oakwood and Woolston went up in one long push after Warrington was named a new town in 1968, and building was still running into the early 1980s. The town has not stopped since.
Another 228 homes are proposed at Winwick alone, with more than 2,000 in the pipeline around the village, according to the plans lodged this month. The houses built fifty years ago are still standing, and their wiring has not changed at all.
What the board was built for
A New Town house was wired for a household with a television, a fridge, a washing machine and an immersion heater. Four or five ways in a small consumer unit, fuse wire rather than breakers, and three sockets in a living room counted as generous. Nothing in that design was wrong for 1975. It has simply never been revisited.
What gets plugged in now
An electric car charger pulls 7.4 kilowatts on its own. An induction hob can draw 7.2. A heat pump runs a few kilowatts for hours at a time, a tumble dryer and a garden office add their own, and the kitchen now has more appliances than the rest of the house combined. None of that was in the calculation when the board went in, and on a unit with no spare ways every addition since has been a spur taken off the nearest circuit.
Three things the old board cannot do
It cannot protect the sockets with a residual current device, because RCD protection only became standard on socket circuits with the 17th edition of the wiring regulations in 2008. It cannot be extended, because there is nothing left to extend. And it probably cannot pass a modern inspection, because consumer units in domestic properties have had to be enclosed in non-combustible material since 2016, which no 1970s plastic unit is.
The parts nobody looks at
Fifty years of alterations leave a trail: a kitchen extension, a conservatory, a loft conversion, an outside socket for the mower, each one wired off whatever was closest. Cable insulation from the 1960s and 1970s goes brittle, and some of it leaves a green sticky residue at the terminations. In the older terraces nearer the town centre the lighting circuit may carry no earth at all, because earthing lighting points only became standard practice in 1966. None of this is visible from the hall cupboard.
What a condition report tells you
An electrical installation condition report is the honest starting point. An electrician inspects and tests the whole installation, then codes what they find: C1 for something dangerous now, C2 for a potential danger, C3 for an improvement worth making, and FI where a circuit needs further investigation. A homeowner has no legal duty to hold one. A landlord does, and has had to have the electrics tested at least every five years since 2020, a duty extended to social housing last year.
The order to do it in
Get the report before deciding anything, because it separates the urgent from the tidy. The consumer unit comes next, and replacing one is notifiable work under Part P, so it comes with a certificate and a building control notification. Circuits that failed the report come after that. Anything new that draws serious power, an electric car charger or a heat pump, comes last, and only once the board has the capacity to take it.
Cost is the other thing people want to know first. Rates listed for a Warrington electrician run from about £32 an hour to £90 an hour, or £224 to £432 for a day, depending on the firm and the job. Two firms quoting the same board can be at opposite ends of that, which is why the report matters more than the hourly rate.
If the house dates from the New Town years and the board still takes fuse wire, that is not a period feature worth keeping. It is the one part of the house that has never been upgraded, and it is carrying more than it was ever asked to.
