Some insurers may give a discount where the property is protected by an approved and annually maintained burglar alarm system. However, if a discount has been given the insurer may apply additional terms requiring you to set the alarm every time the property is left unoccupied and also when you retire for the night. If this term has been applied and not adhered to it may result in a claim being rejected or not paid in full.
In some instances the installation of an approved and maintained alarm system may be a requirement before cover will be granted.
