Electrician in Colindale

Electricians in Colindale: what is different here

Tripping in a new flat: where the fault usually is

Most Colindale flats have a modern consumer unit with a protective device on each circuit, so a fault trips one circuit rather than the whole flat. That makes the starting point easier: tell us which breaker has gone and what was running at the time. Common causes in these flats are a washer-dryer or dishwasher developing a fault, water getting into a balcony light or outside socket, a failed extractor fan in an internal bathroom, and a kitchen appliance plugged into an overloaded adaptor.

A useful test before calling: unplug or switch off every appliance on the affected circuit and reset the breaker. A breaker that now stays on points to one of those appliances; one that drops again with the circuit empty points to a cable, socket or fitting, which is our job.

Electric underfloor heating and heated bathrooms

Some Colindale flats are heated partly or wholly by electricity. The installer's case study for Beaufort Park describes electric underfloor heating mats under bathroom floors, heated wall panels and heated mirrors in apartment bathrooms. When one of these stops working, the cause is more often the thermostat, its floor sensor or the supply than the mat itself, and those can be tested and replaced without lifting a tile.

If the mat has failed, the fault can sometimes be located under the floor so that only a few tiles come up. We tell you what the tests show before anything is lifted. Panel heaters in all-electric flats can be replaced like for like; a different type or size of heater can change the flat's energy rating, so mention it if you are a landlord.

The heat interface unit belongs to the heat supplier

In Colindale Gardens and the new Grahame Park homes, heating and hot water come from a heat network through a heat interface unit. The unit has an electrical supply from the flat's consumer unit, and that supply, its isolator and its fuse are ours to check. The unit itself, its controls and its pump are normally maintained by the heat supplier or the managing agent.

So if the heating and hot water have stopped, check whether the unit's display or lights are on. If it has no power, call us. If it has power but no heat, call the heat supplier first, because it is likely to be a network or unit fault rather than an electrical one.

Alarms, fire strategy and the Building Safety Act

New flats are fitted with mains-powered, interlinked smoke and heat alarms as part of the building's fire design. Replacing a failed alarm head with the same model or an approved equivalent is routine. Moving an alarm, adding one in a new position or changing the type alters the fire strategy, so we ask for the managing agent's agreement first. Blocks of at least 18 metres or seven storeys with two or more homes are higher-risk buildings under the Building Safety Act 2022, registered with the Building Safety Regulator.

Under section 95, residents and owners must not interfere with safety items in the common parts. We do not touch corridor detectors, smoke vents, emergency lighting or anything else outside your front door; those go to the managing agent.

Sockets and lights in concrete and plasterboard

Adding a socket in a Colindale flat depends on what the wall is. Plasterboard partitions on metal studs take new cable runs and back boxes fairly easily. Concrete party walls and columns are harder to chase, and many leases forbid cutting into structural or party walls without consent. Where a wall cannot be chased, a neat surface run or a different position on a partition wall usually solves it.

New circuits and changes to the consumer unit are notifiable under the Building Regulations, and we issue the certificate. Many Colindale leases ask for copies of certificates for alterations, so keep ours with your lease papers, and send a copy to the managing agent if your lease requires it.

Older wiring on and around Grahame Park

The privately owned homes that remain from Grahame Park's 1970s estate are a different job. Their installations may be original wiring extended over five decades, a partial rewire, or a full rewire, and older consumer units without residual current protection are common. For a landlord, these are the homes where an EICR is most likely to bring remedial work.

For an owner-occupier planning to stay until the regeneration reaches their block, we price the work that makes the installation safe and leave the choice of anything further to you.
