Around 72% of those that have announced what they are doing have opted to pass on between 0.15% and 0.99%, amongst them some of the UK's biggest mortgage lenders.
Five lenders still have an SVR of 6% or above: Stroud & Swindon BS, Kent Reliance BS, Chesham BS, Market Harborough BS, and Darlington BS, according to Moneyfacts.
Michelle Slade, analyst at Moneyfacts.co.uk, commented: "With each base rate cut, the number of lenders passing the cut on in full to their SVR continues to dwindle. It is likely that some lenders have already cut rates as low as they are prepared to go.
"With Stafford Railway BS cutting its SVR to 3.99%, it is disappointing that other building societies have SVRs over 6.00%.
"Some building societies are opting not to cut their SVR so they can offer higher rates to their savers. However, the three lenders with the highest SVRs have all cut savings rates by more than the base rate cut.
"Customers with Cheltenham & Gloucester, Lloyds TSB Scotland and Skipton BS should continue to benefit as these lenders have a guarantee to offer an SVR at a set percentage above base rate."
