The lender is cutting rates on its fixed deals by an average of 0.14%, meaning it is now offering two-year fixes from 2.58% and five-year fixes from 3.64% at 70% LTV.
It is also increasing rates on its tracker mortgages by an average of 0.30%, while two of its offset deals will see rate increases of up to 0.20% and four offset products will see application fee rises of between £500 and £1,000.
For instance, its offset lifetime tracker at 70% LTV has gone up from base + 2.48% to base + 2.59%, and had its application fee increased from £999 to £1,999.
The lender is maintaining the rates on approximately a third of all its products.
A spokeswoman for Barclays says: “These changes support our continued focus to provide good priced mortgages in a highly competitive market.
“This is against a backdrop of a series of economic indices over the last few weeks, which have influenced the funding in the market, for example concerns surrounding the Eurozone and a second global recession.”
