How much does a burglar alarm cost?
Depending on your requirements; a professionally fitted, insurance approved, wireless audible only system, for a three-bedroom home, will typically cost around £500 - £800.
Remote monitoring or an app-controlled system will probably cost an additional £150 - £200.
If a lengthy service contract isn't a problem or ownership isn't vital, then, some companies will install a system for an installation fee of less than £100, or even free of charge.
With reasonable DIY skills, fitting a basic wireless alarm is quite straight forward. Yale manufactures some great value basic kits, available from Argos, Screwfix, DIY stores or online from around £150.
