EICR certificates in Neasden, NW2

In the Neasden census neighbourhood, flats and houses are close to level: 51% of homes are flats, near London's 54%. Council tax records for the same area date 62% of homes to between the wars and 17% to before 1919. Homes of that age may have been rewired, sometimes more than once. The inspection looks at the age of the consumer unit, at RCD protection where the current standard expects it, and at the earthing and bonding to gas and water pipes. A rewire done in stages can leave any of these behind the rest.

Private renting stands out: 47% of households rent from a private landlord, well above London's 30%. Houses split into flats are also more common than across London, at 17% of homes against 11%. A house built for one family and later divided usually has a meter and consumer unit for each flat, and a landlord supply for the shared parts. Where that separation was never completed properly, the report notes it, because a circuit shared between two supplies makes safe isolation harder.

The work on the day depends on the building. For a whole house, the number of consumer units, any loft room and any outbuilding with power all affect how long the visit takes. For a flat in a converted house, it helps to know where the meter cupboard is and who can open it. The electrician has to isolate your supply without cutting off the neighbours. The Grange, grade II, is the only listed building within 300 m of the centre of Neasden.
