Not all lenders would appear to offer such mortgages and moneysupermarket.com lists the best ones. I dodnt know much about this subject however I have £100,000 in savings with easy access paying on average 3.15 % for the next 10 months but a mortgage of £156,000. I am retired and will seek new employment at some point after a break from working. Does the off set principal work on the basis that any interest rate offered eg 3.79 % for example for fixed term of two years only apply to the difference between the mortgage eg £156,000 and the savings eg £100,000 which is £56,000 ? Any one explain if this is correct or not ?

many thanks
