Common questions

When should I start looking for a new deal?

Many lenders let you secure a rate up to six months before your current deal ends, so start then to avoid moving onto your lender’s standard variable rate.

What is a product transfer?

A new deal with your current lender. It usually needs fewer checks and no legal work, but switching lenders may get you a better rate.

Should I add the fees to my mortgage?

It saves paying upfront, but you then pay interest on the fees for the rest of the term.

How we calculate

Every calculator uses the published 2026/27 rates from one shared set of rules, so when a rate changes, it changes everywhere.

Where rates come from

Tax, National Insurance, student loan, benefit and property tax rates come from GOV.UK. Each calculator links to its sources.

What we don’t cover

Scottish income tax bands, tax codes other than 1257L, benefits in kind and your personal circumstances. Results are estimates to help you plan, not a payslip or advice.
