The future of residential building electrical installations

Arran Cameron
This is a spin-off from the discussion What is the best way to wire ceiling lights.


What do you think is the future of residential building electrical installations in 20 to 30 years time? Will they in modern and modernised houses be significantly different from what they are today or will they most likely be barely changed from what they are today?


Will consumer demand be a driving force for change or will electricians only make changes from the status quo in order to comply with updated wiring regs?

    • Network operators will stop providing customers with an earth terminal for new properties, they will all have to be TT with foundation earthing.

    • The standard maximum demand for domestic properties will be set at 45-amps with tariffs that enforce a penalty tariff if you exceed the agreed maximum demand for your home, so domestic main switches will have a built in trip to disconnect the installation if it looks like usage is going over the agreed level.

    • The number of circuits installed in a domestic installation will be reduced from what people currently consider is required, back to a cooker circuit, a lighting circuit, a couple of socket circuits and a heat pump circuit, so around five circuits.

    • With the reduced number of circuits it will become viable to install arc protection to all circuits along with double pole RCBOs.

    • The lighting circuit will be so well constructed with maintenance free LED lighting without any potential points of failure, so having more than one lighting circuit will be pointless, but there may be emergency lighting to most areas anyway in case of outages.

    • All homes with parking spaces will have EV charging points along with solar PV if external space is available and battery storage.

    • All homes will have the battery storage anyway to even out the demand.

    • More homes will have renewable hot water systems, such as wet panels on their roofs.
