If the Bank of England cuts the base rate on Thursday; the mortgage lender will automatically cut its standard variable mortgage rate - currently at 3.0 per cent - by the same amount on 1 April.
Existing tracker customers will also benefit from any rate cut from 1 April. The lender does not have a collar on its trackers so product rates have the potential to go to 0% if base rate continues to fall*.
Since base rate began to fall in December 2007, the lender has cut its standard variable rate by the full 4.75 per cent. On a typical repayment mortgage of £150,000, this represents a monthly saving of over £420. If rates are cut by 0.5 per cent again on Thursday, tracker and variable rate customers are set to make a further monthly saving of £38.
Stephen Noakes, C&G commercial director, said: "There are differing views on what action the Bank of England will take tomorrow and a rate cut is not a dead cert. If base rate does fall, we will pass it on to tracker and variable customers, who are already hundreds of pounds a month better off."
Should base rate be cut, the lender will review wholesale funding costs to see if any saving can be made on new fixed and tracker products.
