Power Requirements For ONT terminal

[GyFU]

I'm having fibre 100 installed on 3 February by Sky technician and part of that will be installing a ONT terminal. My telephone box is in a bedroom at the side of the house and that is where my SR203 is located. This bedroom is more of an office and only has two power points and I use power extensions cables for the various items of office equipment. My understanding is that these will not be suitable for powering the ONT which needs a power source of its own? Not sure whether that is correct? I have time to get another power point put in before the Sky ONT appointment but dont want to do so if it can be avoided. Advice please.

There's no significance in powering an ONT from an extension bar: it makes no difference to speed or stability.
