Make sure your callers can make themselves heard by installing a bell or chime for them to ring. You can choose a battery or mains-powered model.

A doorbell or chime is a more reliable way for callers to announce their presence than a knocker, because you can place the sounder where you are most likely to hear it.

You need minimal DIY skills to install a battery-powered bell - just the ability to drill a few holes and drive in some screws. Fitting a mains-powered bell requires basic electrical skills to ensure that the mains connections are made correctly and safely.

Care needs to be taken when connecting up a bell transformer permanently to the mains supply. There are no safety risks involved in fitting a battery-powered bell.
