The mutual has shaved 0.20% from its 85% LTV fixed rate products.
New headline mortgages, all with a £995 fee, include two, three and five year fixed rates at 3.84%, 4.09% and 4.44% respectively.
Offset alternatives are available across and are priced only 0.20% higher than the non-offset equivalents.
Sunjeev Sahota, Yorkshire Building Society Product Manager, said:
"These are very competitive rates and we remain committed to helping as many people as possible achieve their property aspirations.
"By making reductions at the 85% LTV level we are ensuring that those with smaller deposits can benefit from the widespread cuts in rates we have seen across the market recently."
