Plumbers & electricians in Southborough and St John’s

St John’s grew up along the road running north out of the old spa town in the second half of the nineteenth century. Its church opened in eighteen fifty-eight, built of Kentish ragstone where most churches in this part of Kent are sandstone, and the streets off St John’s Road and through Culverden filled with Victorian and Edwardian terraces and villas in the decades that followed. High Brooms came later and faster. A brick and tile works was founded there in the eighteen eighties, the station opened in eighteen ninety-three under the name Southborough, and within two or three decades the farmland had become a district of workers' terraces, many of them built from bricks made a few hundred yards away.

Southborough is its own town, with its own town council, strung along the A26 towards Tonbridge. It was part of Tonbridge until eighteen seventy-one and grew quickly after eighteen seventy-nine, when the Holden estate was sold and laid out for new houses. The common at its centre, seventy-one acres of it, has hosted cricket for over two centuries, with older cottages around its edge and twentieth century housing filling much of the land behind. Rusthall, to the west across its own common and the sandstone of Toad Rock, grew as a suburb once the railway reached Tunbridge Wells, and only became a parish in its own right in two thousand and eleven.

Most of it was connected to the mains when a house ran lights and a kettle. In some streets that still shows.

Looped electricity supplies in older terraces

---

In a lot of older terraces and semis the network never ran a separate cable to every front door. It ran one service cable from the main under the pavement into the first house, and from that house’s cut-out a second cable carried on through the wall to the neighbour. That is a looped supply, and it was a perfectly sensible way to connect two houses that between them drew a few amps for lighting and an iron. The catch is that both homes are now sharing one cable and, on that shared length, one fuse rating, so the capacity each household assumes it has is in truth a share of something smaller. It holds up fine for ordinary living. The trouble arrives with the big modern loads: an EV charger, a heat pump, a larger electric shower, or a request for a bigger supply. Each of those assumes a cable serving one house, and before most of them can be connected the network operator has to be told about them, at which point a looped service is one of the things that can stall the application or turn it into a separate piece of work. There is a quieter consequence as well. Because the cable is shared, a fault on it, or the network’s fuse on that length operating, can take out both houses at once, and work at the intake of one house can mean the other going without power while it happens. Nobody living in either house notices any of this until they try to add something large.

Spotting one is usually a matter of looking rather than testing. Open the meter cupboard and find the black cut-out where the cable comes in from the street. If two sets of cables leave it, one to your meter and another disappearing through the wall or under the floor towards next door, the supply is very likely looped, and the house at the far end of the loop may have no cable of its own from the street at all. Look, but touch nothing before the meter. The cut-out and its seals belong to the network, and the meter belongs to your supplier.

Only the network operator can unloop a supply, and in this part of Kent that is UK Power Networks, which does it by running a new cable from the main to the second house. Some network operators now do this at no cost to the householder when a charger or heat pump needs it, but whether UK Power Networks charges for a given address, and when it can come, is its decision, so it is asked rather than promised. Our part is to recognise the loop while the job is being planned, tell you before anything is bought, and put our work in the right order around the network’s visit. Plenty of houses in TN4 are not looped at all. One look at the cut-out settles it.
