The lender is offering two and five-year fixes at rates of 3.29 per cent and 3.69 per cent respectively.
The two-year deal comes with a product fee of £999 while the five-year has a fee of £499, both deals are also available for product transfer and further advances.
Jonathan Stinton, head of intermediary relationships at Coventry Building Society (pictured), said: “There’s plenty of demand for 90 per cent LTV products and we’re in a position to support the market by bolstering the supply of these higher LTV deals.
“This provides more choice and certainty for brokers and their clients – particularly first-time buyers but also movers and remortgagers.”
In recent months, the lender had been dipping in and out of the market, offering 90 per cent LTV deals for a couple of days at a time.
Stinton added: “Our short-term launches were both popular and effective in the circumstances, but the market for 90 per cent LTVs is now beginning to strengthen.
“We can now continue to support the market this year by offering competitive, high LTV products along with some certainty for brokers that those types of products will be available for some time.”
