Is your mortgage from TSB Whistletree?

We are acting on behalf of thousands of mortgage prisoners who have been trapped paying excessively high interest rates on their mortgages.

Following the 2008 financial crisis, Northern Rock and a large proportion of its loan book were nationalised. Over time, the government has sold these nationalised assets back to private companies. Rather than gaining access to new, competitive mortgage products, these former Northern Rock customers have been trapped unable to switch onto cheaper products.

In general, when you take out a residential mortgage the interest is set at an introductory rate for a few years before changing to the lender’s reversionary rate, which is often called the ‘standard variable rate’. The reversionary rate is normally set at a higher level than the lender’s introductory rates and is used to encourage borrowers to re-mortgage and take advantage of the lower introductory rates. Such a model benefits borrowers and lenders; lenders generate fees on the transition and borrowers benefit from interest rates below the standard variable rate.

This ceased to be the case for mortgage prisoners, who because of changes outside their control, including their lenders ceasing to offer new lending and becoming inactive lenders, and changes made to the affordability criteria by the FCA were unable to access new products even where they were managing to maintain their mortgage repayments.

Borrowers who were unable to re-mortgage had no choice but to pay the high rates set by their inactive lender or face losing their home. For this reason they are known as ‘Mortgage Prisoners’. There are hundreds of thousands of Mortgage Prisoners in the UK.

Harcus Parker is acting for individuals to reclaim the difference between the high interest they have paid on their mortgages and the interest they would have paid if the rate had been set by their lender at a lower ‘fair’ level. The amount of compensation due to homeowners who join the litigation could be significant. The litigation is free at the point of use. We are acting on a no-win, no-fee basis, and will pay any third-party costs which are necessary in order to progress the claims to trial.

It is important that you stay up to date with your mortgage repayments. You should not expect your financial difficulties to be solved by the claim.
