Quick answer: Mortgage prisoners are homeowners stuck on their lender's standard variable rate because they cannot remortgage — usually because their lender no longer offers new products, or affordability rules block a switch despite never missing a payment.
An estimated 200,000 UK homeowners are mortgage prisoners — paying SVR rates of 6–9% when fixed rates may be below 5%. Most became trapped when lenders collapsed or withdrew from the market after the 2008 financial crisis, or when FCA affordability rules prevented switching despite perfect payment history.

Why people become mortgage prisoners
The most common cause is lender failure or withdrawal. When Northern Rock, Bradford & Bingley, and other lenders were nationalised or sold, their existing customers could not access new deals from the successor entity.
FCA affordability rules introduced after 2014 also trapped borrowers who could afford their current payments but could not pass stricter stress tests for a new lender — even at a lower rate.
FCA and government remedies
The FCA introduced modified affordability assessments allowing active lenders to consider a prisoner's payment history rather than applying full stress tests.
The Mortgage Charter (2023) committed lenders to offering prisoners internal product switches without affordability checks if they are up to date on payments.
Steps to try to escape
Contact your current lender and ask about internal product transfer options — many now offer these under the Charter.
Speak to a mortgage broker experienced with prisoner cases. Modified affordability rules may allow an active lender to take you on.
If your lender is inactive, the Financial Conduct Authority and MoneyHelper can signpost support. Campaign groups like UK Mortgage Prisoners also provide guidance.
Common questions
Can my lender force me to stay on SVR?
If your lender no longer offers mortgage products, you may have no internal switch option. External remortgaging depends on modified affordability rules and broker willingness.
Will being a mortgage prisoner affect my credit score?
Being on SVR does not directly harm your score. However, higher payments may increase your debt-to-income ratio, which affects future lending decisions.
Is there compensation for mortgage prisoners?
There is no general compensation scheme. Some cases involving specific lender failures have seen redress, but most prisoners must focus on finding a route to a better rate.
