Across all mortgages currently on the market, the typical fee being charged has risen by £112 since the start of 2013 to reach £1,522, marking the highest average figure recorded by Moneyfacts.co.uk in 25 years.
Banks and building societies' mortgage fees have soared to a new high, despite Government efforts to make borrowing easier, a financial information website has warned.
A borrower with a 10% deposit who is searching for a two-year fixed-rate mortgage would have seen the average fees attached to such deals increase by more than £500 since January.
Mortgage rates have been plummeting since the Government launched a multibillion-pound scheme called Funding for Lending last August, which gives lenders access to cheap finance so they can pass on the benefits of this to help borrowers.
But Moneyfacts warned people to be aware of a sting in the tail that comes with some ultra low-rate deals in the form of hefty fees. Some people may find it works out cheaper to go for a product with a slightly higher rate but a lower fee.
Sylvia Waycot, editor at Moneyfacts, said: "It's easy to get caught up in the excitement of heavily marketed mortgages that shout about low interest rates, but beware that they will often be at the expense of high fees... If the Government is serious about re-kindling the mortgage market with its Funding for Lending scheme, it should ensure all its subscribed lenders offer mortgages that exclude hiked up charges that are hidden behind low rates."
Lenders have been reporting signs of a tentative recovery in the housing market in recent months, particularly among the first-time buyer market, a sector which has been struggling to get mortgage access since the onset of the credit crunch.
The Council of Mortgage Lenders (CML) has reported that first-time buyers have recently been accounting for around 42% of all mortgage loans handed out to home buyers, amid signs that it is getting easier for people to get on the property ladder.
Mortgage lenders also told a recent Bank of England survey that they expect to step up competition to push their rates down further in the next few months.
However, Moneyfacts' figures indicate low-deposit borrowers such as first-time buyers are seeing particularly strong increases in the fees that accompany the new mortgage deals on offer.
