The direct-only deal is available from today with a £1,695 fee. An offset option is available at 1.94 per cent.
Chelsea Building Society product manager Sunjeev Sahota says: “We’re committed to providing the most competitive mortgages and are pleased to be able to offer another market-leading short term fixed rate.
“The Chelsea has made a strong start to mortgage lending in 2013 and now we’ve reduced what was already an excellent best buy product by a further 0.15 per cent, which will appeal to home buyers with a larger deposit or homeowners wanting to remortgage.
“Offset mortgages are particularly popular among Chelsea borrowers so we’re glad to be able to offer the additional choice of an offset version of such a competitive mortgage.”
