What this site is for

This site explains what happens to a mortgage payment or a savings rate when the Bank of England moves the base rate, and how long that usually takes to show up. It draws on published figures from the Bank of England, the Office for National Statistics, the Financial Conduct Authority and MoneyHelper, each one dated to the decision or release it follows.

What it does not do

This site provides general information about interest rates and does not constitute financial advice. It does not lend money, broker any product, compare providers, recommend a particular mortgage or savings account, or take an application on anyone's behalf. It does not hold authorisation from the Financial Conduct Authority or any other regulator, and it does not present itself as a firm that does.

Where the figures come from

Every rate, spread or lag mentioned on this site names its source in the same sentence it appears in, so a reader can go back to the original release. Sources used across the site include:

• The Bank of England, for the base rate itself and the minutes of Monetary Policy Committee decisions
• The Office for National Statistics, for inflation and wider economic data
• The Financial Conduct Authority, for rules that govern how mortgage and savings products are sold
• MoneyHelper, for guidance on managing a mortgage, savings or debt

Where the Bank of England or the ONS revises a figure after publication, the page carrying it is updated to reflect the newer release.

When the next question needs a regulated person

Working out what a rate change does to a monthly payment is a different task from deciding what to do about it. For that second task, MoneyHelper (moneyhelper.org.uk) sets out free guidance on mortgages, savings and debt, and the Financial Conduct Authority (fca.org.uk) keeps the register of firms permitted to advise or lend. If a complaint against a regulated firm needs resolving, the Financial Ombudsman Service (financial-ombudsman.org.uk) is the route for that. This site's own explanations sit alongside those services; how a base rate change reaches your money and the base rate now cover the mechanism, and contact is there for questions about the site itself.
