Santander is offering a market-leading rate of 4.6% on loans of between £7,500 and £15,000 as part of a flash sale.
This is the cheapest rate available on loans of this size, but it will only be around until midnight on Wednesday 4th December.
Borrowers taking out a loan of £10,000 at this rate for five years can expect to pay back a total of £11,187.60 or £186.46 per month.
Personal loan changes
The bank has confirmed it will be reducing rates across a number of other loans in the coming weeks.
Competition in the personal loan market is fierce and rates have fallen steadily in the past year.
Clydesdale Bank and Yorkshire Bank have also lowered the rate of interest on their loans of between £7,500 and £15,000 to 4.9% this week.
There isn't a great deal of difference among providers but here I've listed the top five cheapest loans.

Competition in the loan market
In the past year providers have slashed the rates of personal loans in an effort to secure more customers and remain at the top of the tables.
At the start of the year changes were occurring almost every week, but now the trend appears to be lowering a loan rate for a limited time. Sainsbury's started this at the start of November when it dropped rates across a number of loans for a couple of weeks.
This means borrowers are forced into acting quickly before the rate is taken away. Providers can therefore apply pressure on people to sign up, but don't have to commit to lowering their rates permanently.
The interest rate advertised will also not be available to everyone, even if you are successful with your application. Lenders are only obliged to offer the advertised rate to 51% of successful applicants.
