The direct-only brand, which is part of the Yorkshire Building Society, is also providing an offset option at 2.19 per cent. Both products come with a £995 fee.
Chelsea Building Society product manager Sunjeev Sahota says: “These are superb rates – market-leading and the lowest short term fixed rates we have ever offered. Whether buying a home or remortgaging, borrowers can be confident that these fixed rates give them the security they need at a fantastic rate. There is also a great opportunity here for those looking to remortgage to bring down their mortgage repayments.
“The Chelsea is unusual in offering offset alternatives to all mortgages in its product range so we are pleased to give borrowers the additional choice of an offset version of such a competitive mortgage.”
