The lender is launching a 10-year mortgage with a rate of 2.74% at 60% loan to value (LTV), with no product fee.
And two new two-year deals for buyers with a 5% deposit are being added, one with no product fee and the other with a £999 fee at rates of 3.5% and 3.34% respectively.
Barclays will also offer a five-year fix at 95% LTV at a rate of 4.04% with a product fee of £499, as well as an option with no fee at a rate of 4.14%.
At the same time, rates on a number of two-year purchase and remortgage trackers at 75%, 70% and 60% LTV have been reduced.
Barclays said it was making the changes to remain competitive in the market.
It comes after a wave of lender product changes in the wake of the Bank of England base rate hike earlier this month.
A number of lenders have increased their Standard Variable Rates, with NatWest the latest to confirm this week with a 0.25% increase to the default rate, taking it to 4.24%.
Santander, Lloyds and TSB have already announced 0.25% increase to variable rates.
