Customers have less than a week to sign up to Eclipse Internet's broadband services and receive up to £100 of high street vouchers for free.
The promotion, which is available to all new home and business customers, is expected to end of December 14th.
Home broadband customers can get their hands on a £30 or £50 voucher for taking up the company's Home Select and Home Pro packages respectively, while coupons ranging from £20 to £100 are available to companies depending on the deal they take.
Clodagh Murphy, Director of Eclipse, said: "Our new customers are really pleased to be getting this extra gift and I would like to personally welcome them to Eclipse.
"There is still time left to sign up to Eclipse and take advantage of the festive offer."
Eclipse Internet was originally established in the south-west of England in 1995, while its first national broadband service was unveiled in 2001.
