TalkTalk has boosted the appeal of its broadband and home phone services by offering a £25 Tesco voucher to new subscribers.
UK households signing up for the firm's Essentials and Plus broadband packages can take advantage of the new gift certificate offer.
With TalkTalk Essentials, consumers can download at speeds of up to 14Mb, and take advantage of a 40GB monthly usage allowance.
As well as high-speed broadband, subscribers can make unlimited landline calls on evenings and at weekends.
At present, the broadband deal is available at half-price for 12 months, meaning consumers pay just £3.25 per month for internet services and off-peak calls.
Since they are only required to sign up for one year, broadband and calls are available at a 50 per cent discount for the entire year.
Customers signing up for TalkTalk Essentials online also receive a free connection, helping to keep start-up costs to a minimum.
Households seeking unrestricted use of their landline and an unlimited monthly download allowance can sign up for TalkTalk Plus.
They are entitled to a six-month 50 per cent discount on broadband and calls - meaning TalkTalk Plus is initially available for £7.25 per month.
A free connection is also available with this higher-tier broadband deal, which along with the free £25 Tesco voucher may help persuade consumers to switch to TalkTalk this month.
