"They didn't tell you when you first sign up. I said is there going to be any more cost?"
Mr Butt said if a device such as an alarm or camera was currently using the internet, it would most likely work on the fibre network but if it didn't the devices would probably need upgrading.
People needed to ask their providers, he said.
"If it's already via the internet it won't be affected at all by fibre."
Mr Butt said there were several ways to have multiple phones, but buying a wireless set-up for a relatively low cost was the best solution.
"Imagine you bought a car and your car was too big for the garage. Would you complain to the car manufacturer?"
The cost of upgrades to equipment was relatively low compared to the annual cost of fibre broadband, he said.
