The Lifetime Mortgage product is now available at a lifelong fixed rate of 6.29 per cent, whilst the Lifetime Mortgage Extra's rate has been trimmed to 6.55 per cent.
The former is available to 45 per cent LTV and the latter to 55 per cent LTV. Both come with a product fee of £599.
Kirsty Jackson, head of lifetime mortgages at Mortgage Express, said: “Our best-buy lifetime mortgages are ideal for customers aged 60 or above who are looking to unlock equity from their homes.
"By opting for a highly competitive interest rate that is fixed for the life of the loan, customers gain peace of mind because they know precisely what their commitment will be at any time in the future.
"Neither of our lifetime products has an upper age limit in place, enabling older customers to take advantage of the great rates on offer too."
