Scots who re-mortgage their homes next year will be paying nearly £200 more a month, Labour analysis suggests.
The party estimates that 546,600 households in Scotland will re-mortgage by 2026, and those that do so next year will pay an average of £190 more a month.
Labour shadow Chancellor Rachel Reeves said that Labour would protect mortgage holders ahead of a visit to Glasgow on Friday.
She blamed "the toxic combination of a Tory mortgage bombshell and an incompetent SNP distracted by scandal" for the increasing costs.
The figures estimate that 29,500 homes in Aberdeenshire will be affected, with those re-mortgaging next year paying £210 more a month on average.
The predicted 14,800 homes in Dundee which will re-mortgage will pay £150 more a month.
In Edinburgh, some 51,700 homes are predicted to re-mortgage and will pay £280 more. The 51,700 homes in Glasgow City will pay £180 more a month.
Labour said it would protect mortgage holders by making the regulator to require all lenders to bring in measures such as allowing borrowers to switch to interest only mortgage payments for a temporary period or to lengthen the term of their mortgage period.
The UK Government currently has the same rules but they are not mandatory.
Reeves will visit Centrica Green Skills Centre in Glasgow with Scottish Labour Leader Anas Sarwar and Shadow Business Secretary Jonathan Reynolds on Friday morning.
She said: “Across Scotland, families are being hit hard by the toxic combination of a Tory mortgage bombshell and an incompetent SNP distracted by scandal.
“Unlike both these governments, Labour will not stand by while Scots face the reality of those failures.
“Not only has their economic recklessness driven this crisis, but this Tory government's failure to make its measures mandatory leaves households across Scotland missing out on the mortgage support they need.
“Labour’s mandatory plan and our Mortgage Rescue Scheme to ease the Tory mortgage bombshell offers Scottish families practical help now, while our commitment to fiscal responsibility and growth will secure our economy for the future.”
A UK Treasury spokesperson said: “The best thing we can do to help mortgage holders and renters is to drive down inflation, and we have a clear plan to halve it this year, then get it back down to 2%.
"The mortgage charter sets out targeted support measures for mortgage holders who are understandably anxious about high interest rates and the risk of losing their home.
“That’s on top of the £3,300 on average we are giving each household to help with the cost of living over this year and last.”
