Paul Elliott, head of mortgages at Atom said: “We’re delighted to be offering truly competitive rates on our 90% and 95% mortgages, to help home buyers ahead of the fast-approaching stamp duty cost increase.
“We are proud that we can help both first-time buyers and those wishing to move, ensuring that our valued customers are getting great rates, on what for many, will be their first mortgage.”
