Laoiseach Lynch, head of mortgage products for Barclays, said: “This is the seventh time in a row that we have made substantial cuts to our mortgages, including some of the biggest rate cuts this year.
“The mortgage market is highly competitive at the moment with providers cutting rates on a regular basis. This is great news for borrowers as they are getting access to some of the lowest ever rates.
“Our rate cuts this time are focused on higher LTVs as we aim to make borrowing more accessible and affordable for those with a smaller deposit. These changes are consistent with our active participation in the mortgage market and providing some of the best deals available to our customers, helping them save money on their mortgage.
“We urge people to act now, review their mortgage and make the most of these great rates to protect themselves against future base rate increases.”
