EICR certificates in the Royal Docks, E16

In Canning Town South & Bow Creek, the census area the Royal Docks fall in, 32% of homes have one bedroom, against 21% across London. Terraced houses make up 14%, and council tax records put just 6% of homes before 1919. Most of the housing is recent. A recent installation usually has a modern consumer unit and wide RCD protection, though a flat from the early 2000s may have it on the sockets only. The EICR still inspects and tests every circuit. In practice, attention turns to damage, overheating at accessories, and any alterations since the flat was first wired, such as added sockets or a replaced kitchen.

Heating sets the area apart. 31% of homes use electricity only and 12% use communal or district heating, against 13% and 3% across London. Electric heaters and water heating draw heavy current for long spells, so terminals and protective devices on those circuits get a close look. A flat on a heat network usually has a heat interface unit, and the EICR covers the wiring that feeds it and any room controls wired from the flat's consumer unit. Private renting is high too, at 46% of households against 30% across London. Furnished lets often come with plug-in heaters and appliances, which sit outside the fixed installation.

Access is the practical point in a managed block. The electrician needs the flat, its consumer unit and the meter, which may be in a riser or intake room behind a locked door. Arranging that with the managing agent before the day avoids a wasted trip. If the flat has a heat interface unit, its isolator is often in the same cupboard, and that needs to be reachable too. The two listed buildings within 300 m of Custom House are Warehouse K and Warehouse W, both grade II. The count covers only that radius, so check your own building's status before repairs are planned.
