The latest remortgage product will be offered at 2.99% and is available at up to 60% loan-to-value, for loans between £100,000 and £1million.
The lender has also cut rates on its two-year fixed-rate 70% LTV remortgage to 2.69%.
Barclays Mortgages managing director Andy Gray said:
“This is a real boost for UK homeowners, giving them access to even better mortgage deals. Fixed rates are proving increasingly popular with borrowers who are looking for the certainty of securing their mortgage payments over the longer term and with our lowest ever fixed rates on offer, now is a great time for borrowers to review their mortgage arrangements."
