But now research from TotallyMoney and Moneycomms has revealed that a poor credit score could see this repayment leap in cost by tens of thousands of pounds.

They estimate that in the first five years a £207,000 90 per cent loan-to-value (LTV) mortgage could cost buyers an additional £14,857, while this cost jumps to £78,500 extra over a 25-year term.

Additional figures from the analysis also showed that a poor credit score also had a knock-on effect on other areas of lending that could be factored into a household budget. This includes personal loans; here a £7,500 loan taken over four years could cost an additional £7,453. And when it comes to credit cards, paying a £3,000 credit card bill over a period of two years could cost £1,979 more in interest.

Commenting, Alastair Douglas, CEO of credit experts TotallyMoney, said: 'The extra fees people pay for having a bad credit score are huge. Taking the time to check their report means they can understand why this might be happening.

'Lenders review a customer’s credit report when they apply for a product. With a bad score, they’re more likely to charge a higher APR, offer less interest-free months, or even reject an application.

'Being informed about their score can help people to see where to improve and how to get the best deals. A report shows customers up to six years of credit history, and how much credit they are currently using.'
