Andrew Hagger, head of news and press at moneyfacts.co.uk, has looked at the current state of play following the Monetary Policy Committee's (MPC) decision to increase base rate by a quarter point on 3 August.
He said: "With over 80 per cent of mortgage standard variable rate (SVR) changes announced, we have seen a number of providers take the opportunity to make an increase greater than 0.25 per cent with Furness Building Society, NatWest and RBS increasing by 0.30 per cent and Standard Life by 0.31 per cent.
"A lender that has bucked the trend this week is Leeds Building Society who has increased SVR by 0.2 per cent to 6.74 per cent.
"There are a few announcements still to come, including a couple of big players namely Woolwich and HSBC, but we would expect these to be released very soon.
"The Moneyfacts average SVR now stands at 6.57 per cent."
