Emergency electrician in Hounslow and Chiswick

Hounslow's local power network is run by SSEN, not UK Power Networks. If your street is off, call 105 and you will be put through to SSEN. If only your home is off, or something smells hot, switch off at the main switch if it is safe and call an emergency electrician to make it safe.

The homes in Hounslow and Chiswick

The borough runs from Chiswick by the river out to Feltham and the edge of Heathrow. The Valuation Office Agency counts 16% of its 111,270 homes as built before 1919, mostly in Chiswick and around Bedford Park, 29% between the wars across Hounslow, Isleworth and Feltham, and 20% since 2000, many of them riverside flats in Brentford. 49% of homes are flats. That gives a real mix: Victorian houses with wiring altered over a century, interwar semis with older boards, and new blocks with shared supplies and plastic or metal consumer units depending on when they were fitted.

Power cuts in Hounslow: call 105 for SSEN

The Mayor's answer to the London Assembly confirms that Hounslow, Ealing and Hillingdon are served by SSEN. If you search for a UK Power Networks map during a cut, you may not find your street. Call 105 instead: it is free and routes you by postcode. Our guide to power cuts in Ealing and Hounslow explains what to check. SSEN also offers text updates and a postcode checker on its own website, so it is worth saving that page on your phone rather than the UK Power Networks one.

RCDs tripping at night

A common call is an RCD that trips overnight or every few hours. The cause is often something that switches on by itself: an immersion heater on a timer, a fridge freezer defrost cycle, heating controls, or a garden light on a sensor. Small leaks to earth from several appliances can also add up until the RCD trips. Writing down when it happens and what was running helps find it faster. Our advice on an RCD that keeps tripping at night covers the checks.

If the trip happens at about the same time each night, check what is on a timer. If it happens after rain, look first at outside lights and sockets. Note the time and weather each time it trips.

Brentford flats and Chiswick houses

Many riverside flats were fitted with plastic consumer units before the rule change that requires non combustible enclosures in homes. A sound plastic board does not have to be replaced, though an inspector may note it as an improvement. If you are replacing one, it will be metal. Our post on metal consumer units explains why.

Chiswick's Victorian and Edwardian houses, including the Bedford Park conservation area, have wiring that has been altered many times. Extensions at the back, basement conversions and loft rooms are often on separate circuits added years apart. When an RCD trips across half the house, the fault can be in a part of the home that was wired decades after the rest. Notifiable work, such as a new consumer unit or circuit, is self certified by a registered competent person or notified to the London Borough of Hounslow's building control. For a street wide cut, remember that 105 here reaches SSEN, not UK Power Networks.
