Annual Price Increase

What it means for you

Why are the prices changing? 

This is a contractual term we must apply consistently in line with Ofcom's guidance. We also face increased costs associated with running our network and supporting our customers. These include rising energy costs plus the investment required to support the growing demand on our network.  

How much your rental charge changes by depends on your tariff and when your agreement started.
