Plusnet is offering discounts and £50 cashback with several broadband packages.
Among those included in the promotion is the Plusnet Unlimited Broadband & Phone Line deal.
This 12-month contract offers broadband speeds of up to 17Mbps plus unlimited downloads.
The deal costs £20 a month, plus a £10 set-up cost. This means subscribers will see savings worth £95.76 on their broadband across the year.
Customers can also get £50 cashback with the Plusnet Unlimited Fibre Broadband & Phone Line package, which offers unlimited downloads and speeds of up to 38Mbps.
The 12-month contract costs £25 a month, plus a £25 set-up fee, along with free calls to Plusnet Phone customers at any time and a guarantee subscribers will only pay for the calls they make.
Plusnet believes its fibre broadband offering is "perfect for downloading, streaming movies and TV shows in HD, and online gaming", as it is up to five times faster than normal broadband.
