What to expect
Switch your mortgage deal
If your current deal is ending soon, you may be able to switch to a new one early.
This can help you avoid moving onto a higher rate and choose a deal that suits your needs.
You may be able to switch up to 90 days before your deal ends without paying an early repayment charge.
👉 Read our guide to switching your mortgage deal to understand your options and how to get started.
Making overpayments
You may be able to make overpayments to reduce your mortgage balance and pay it off sooner. In some cases, overpayments could also give you flexibility in the future, such as underpaying or taking a payment holiday, depending on your mortgage terms.Borrowing more money
Borrowing more on your mortgage isn’t a simple change, but it may be an option depending on your circumstances.
You might consider this if you need funds for things like:
- Home improvements
- Large purchases
- Other major expenses
Before we can agree to any additional borrowing, we’ll need to:
Assess your income and outgoings
Make sure the new payments are affordable
Review your current mortgage
You’ll need to speak to a Mortgage Adviser to explore your options.
Any additional borrowing is subject to our lending criteria and affordability checks.
Simple changes vs more complex changes
Some updates, like changing your bank details or making overpayments, are more simple and can be done quickly.
More complex changes – such as borrowing more, adding or removing a name, or extending your mortgage term – need a full review with one of our team and can take a little longer.
Some changes sit in between. You may be able to switch your mortgage deal online, or reduce your mortgage term if you've made overpayments, depending on your circumstances and mortgage terms.
If you’re not sure, don’t worry – we'll help you find the right option.

Changing your bank account.
Under the Current Account Switch Service any standing order payment or direct debits will be automatically transferred over to your new bank account. Customers are able to nominate their switch date and the banks have undertaken to make the switch happen within seven working days.
If you simply want to change the bank account that your monthly mortgage payment is taken from, you can do this by calling us on 0345 601 3344. Alternatively you can complete and return our Direct Debit Mandate to thecambridge@cambridgebs.co.uk, ensuring you password protect your document, or send to our Freepost address: FREEPOST THE CAMBRIDGE BUILDING SOCIETY.

Moving home (porting your mortgage)
If your house purchase falls through before completing
If the vendors withdraw their property from the market, or if you change your mind, you should advise your solicitor and Mortgage Adviser as soon as possible. Early notice may help to reduce any legal fees incurred and your Mortgage Adviser can pause the admin process while you decide what to do next.
Changing your solicitor during the conveyancing process
If you have lost confidence in your solicitor during a house purchase or sale, you should speak to a senior member of the firm to try and resolve any issues before deciding to change. One option might be to transfer your case to another solicitor within the firm, who may be better placed to help you. In general, the earlier you make the decision to change, the better, as penalty payments may be incurred if you fail to complete having exchanged contracts. You should also consider the question of payment to the first solicitor for their work to date, this payment will be determined by the terms of agreement you will have signed at the time of appointment.
The Solicitors Regulation Authority (SRA) website sra.org.uk offers further help.
Adding or removing a name on your mortgage
When life changes you may need to change the people who are responsible for making the mortgage payments. This is known as a transfer of equity.
When you applied for your mortgage, we looked at your income and spending commitments to make sure you could afford the repayments. This condition still applies; we will need to look at the income and outgoings of everyone who will be named on the mortgage to make sure it remains affordable both now and in the future. At this time we can also discuss if a new mortgage type or rate would better suit your needs.
Firstly, you’ll need to make a new appointment with a Mortgage Adviser and provide documents which support your income and outgoings. You should also seek legal advice to ensure your financial interests are protected.Changing the term of your mortgage
You may be able to change the term of your mortgage, call our team to find out how we can help.
Changes to your repayment terms
Some mortgages allow you to switch your repayment type. For example you may wish to change from an interest only mortgage over to a repayment mortgage, our team can talk through your options.
Review your Home Insurance needs regularly
If your circumstances have recently changed, make sure your insurance cover is sufficient for you and your family’s needs.
Making overpayments
Paying more into your mortgage account can help you pay off your mortgage before the term ends and also make way for underpayments. You’ll need to check to make sure your mortgage allows this, and be aware of any early repayment charges. Take a look at our overpayments guide, or speak to a member of the team who will be happy to help.
