3 tips for hiring a burglar alarm system installer

While your priority may have been to find the answer to your question of how much does it cost to fit a house alarm, there are other things you need to consider. Here are 3 tips to keep in mind when choosing a burglar alarm installer.

Read reviews

Personal recommendations from friends and friends are always helpful when it comes to hiring a tradesperson. But before you commit to a specific installer, you need to find out more about them. After all, they will be spending time in your home and involved with setting up the security of your home. Check online for reviews from customers to find out their experience with the installer regarding the physical installation and setting up the system, the aftercare provided and maintenance.

Check credentials

In the UK, there are 3 trade bodies that security system companies can join. These trade bodies are the British Security Industry Association, the Security Systems and Alarms Inspection Board and the National Security Inspectorate. For added peace of mind, check whether the installer is a member of one of these bodies before you commit to hiring them. If you have a problem or a dispute with the installation company, an independent intermediary will force the installer to put things right.

Compare quotes

It is standard practice to get 3 quotes from different tradespeople before you commit to using a specific company’s services. Before you hire an alarm installer, make sure they have given you a full breakdown of the costs. Their quote should include the cost of the burglar alarm, their labour and installation costs, and any follow-up maintenance. When you compare quotes, it is good to keep in mind that the cheapest quote is not always the best option for you. If the company offers alarm monitoring services, make sure the police recognise these.
