Absolutely hopeless, don’t use this company or Termguard system.

They don’t return your calls. I’ve been waiting for two months for them to book in a Termguard inspection and refill.
Usual line is “we will call you when we are in the area” but they never call, they will never call you to book it in. They do however continue to send emails stating your service is overdue.
Don’t waste you time and money with this rubbish! NOT WORTH IT!
Never would have got this system if I knew how much hassle.
