First monthly mortgage payment - Why is this sometimes different to my subsequent mortgage payments?

An explanation

When your mortgage is set up, the funds are sent to your solicitor to distribute. This enables you, the customer, to purchase/remortgage your property. Although the mortgage begins from this point you are not required to make a monthly payment until the direct debit is set up. This can be up to 2 months after the funds are released for purchase.

During this time, you have been in receipt of the funds but you have not yet made a monthly payment and interest is accruing. This initial amount of interest is sometimes called the accrual and payment of this interest can either be paid before your first monthly payment or is sometimes taken with your first monthly direct debit payment.

An example

If a customer's chosen direct debit date is the 15th of each month and their mortgage was advanced on the 20th of June, their first monthly repayment would not be collected until the 15th of August. This is because the chosen direct debit date falls within the one month period and therefore the collection of the direct debit defaults to the following month. In this example, the customer would pay initial interest from the 20th of June to the 31st of July.

Initial interest calculation

Initial interest can be calculated as follows:

Mortgage advance amount & * Interest Rate

365 (366 for leap years) * number of days from advance to the end of the month before the customer's first payment

Call us or visit us at one of our branches if you'd like to discuss this further.

Direct debit payments - An easy way to pay your Principality mortgage.

A convenient payment method

As an improved service to Principality borrowers we are able to collect your mortgage repayments by Direct Debit. This easy payment method means that you have no cheques to write, and no continuous paperwork or postage, because your monthly payments are collected direct from your bank. 

If you already pay some of your other household bills by Direct Debit, you will know how easy this method of payment can be. 

How to change to Direct Debit

All that you need do is complete and print our Direct Debit Instruction and send this to us. Please remember to tell us the date on which you would like us to collect your payments. Of course, you can always call us or visit us at one of our branches, if you’d like to talk to us about setting up or changing your direct debit. 

We can collect your payments on either a working day between the 1st and 25th of the month or on the last working day of the month. 

If you wish your payment to be collected on the last working day of the month, please enter your payment date as ‘last day of the month’ 

Changes in your mortgage repayment

We will continue to tell you in advance of any change in your mortgage repayment(s) in the usual way. We will, however, adjust the amount collected from your bank automatically. 

Direct Debits – Your questions answered

Q.Can I cancel a Direct Debit Instruction? 

A.Yes, instructions can be cancelled by contacting your bank. Please also notify us. 

Q.What if I have my Direct Debit returned to my bank unpaid? 

A.We will write to you to confirm we will re-present the direct debit in 10 days. You should be aware that a charge is payable on all returned direct debits. For further details please refer to our mortgage tariff of charges.

Mortgage Payment Types – What are they and can I change my mortgage payment type?

There are three possible mortgage payment types:


Each monthly payment consists partly of capital (the sum you’ve borrowed) and partly of interest (the monthly interest on the sum you’ve borrowed). Provided all payments are made on time, the loan is repaid at the end of the mortgage term.

Interest only

Each monthly payment consists of interest only (the monthly interest on the sum you’ve borrowed). No capital is repaid during the mortgage term. This means that at the end of the mortgage term the amount borrowed will still be owed in full. The borrower takes full responsibility for ensuring that the loan is repaid at the end of the term. This is often achieved by having some sort of investment that, when mature, pays off the capital (the sum you’ve borrowed).

Changing to interest only is dependent on certain criteria being met and our agreement. To discuss this further, call us or make an appointment at one of our branches.

Repayment/Interest only split

This consists of a mix of the above two mortgage payment types, so that part of your mortgage would be on a repayment basis and part of your mortgage would be on an interest only basis.

If you'd like to discuss any changes to your mortgage repayment type, why not call us or make an appointment at one of our branches.

Switching your mortgage deal - What happens when one of my mortgage products comes to an end?

On maturity

When any of the products on your mortgage account are due to mature you will receive notification, at least six weeks before the maturity date, showing the mortgage products that are available to which you can switch.

What you need to know when your existing mortgage deal ends and you want to choose another mortgage deal.

As you are an existing Principality mortgage holder, you will be able to apply for a new mortgage deal either by seeking advice from us or by not taking advice and informing us to carry out your instructions.

It’s important that you read and weigh up these options, before deciding how to apply for your mortgage deal.

Read more here about what you need to know when you change your existing mortgage deal.

If you do nothing

If you do not select anything to replace your maturing product, on maturity that part of your mortgage will attract interest at our Standard Variable Rate (SVR). You can find out more about our Standard Variable Rate (SVR) here.

Term Adjustment – What is it exactly and can I change the term of my mortgage?

Your mortgage term

The term of your mortgage is the number of years you agreed to pay off the loan you borrowed to buy your property. The term will have been agreed with us when you first took out your mortgage. We understand that as your circumstances change, you may wish to change the term of your mortgage.

Adjusting your mortgage term

You can apply to change the term of your mortgage. By agreement with us, you can make the term of your mortgage longer or shorter. Our agreement is subject to our lending criteria and affordability. Please note that adjusting the term of your mortgage will have an effect on your mortgage monthly payments.

If you wish to change your mortgage term, why not call us to discuss this or make an appointment at one of our branches.

Further advance - What is it and how does it work?

What is a further advance?

A further advance, which is an additional loan taken by a borrower who already holds a mortgage with the society. It is secured on the same property as the existing mortgage. All applications are subject to our lending criteria.

Principality further advances – Your questions answered

Q. How much could I borrow?

A. Every application is assessed individually. The amount you will be able to borrow is subject to our application and suitability criteria and affordability. The minimum amount you can borrow is £1,000.

Q. Over what period of time would I repay?

A. Subject to our lending criteria, you can borrow the money over a period of between 2 and 40 years. Repaying your loan over a shorter period of time will mean you pay less interest but your monthly payments will be higher than if you choose a longer repayment term. Repaying your loan over a longer period of time will mean you pay more interest but your monthly payments will be lower than if you choose a shorter repayment term.

Q. Are there any other charges?

A. There is an application fee of £205. There are no charges should you wish to make early repayments.

Q. Can I apply for another further advance if I already have one with Principality?

A. Yes, subject to our lending criteria. You just need to make sure that the total of your loan(s) and mortgage(s) does not exceed 85% of the value of your home and you can afford the repayments.

Q. How do I apply?

A. As an existing Member it’s easy to arrange. Simply call us or pop into your local branch and a member of staff will be happy to help.

If you wish to discuss taking out a Principality further advance, why not call us or make an appointment at one of our branches.

Transfer of equity - What is it?

What is a transfer of equity?

A transfer of equity is the removal or addition of someone named on a mortgage. Sometimes, when your personal circumstances change, you may wish to add someone or remove someone to your mortgage. A transfer of equity needs our approval and is subject to our mortgage lending criteria and affordability.

If you wish to add someone to your mortgage or remove someone from your mortgage, you can discuss that with us. Simply call us or make an appointment at one of our branches.

Bereavement - What happens when a Principality customer dies?

If you've suffered a bereavement, please accept our condolences.

When a mortgage customer dies, we will need to see the original death certificate or a certified copy of the original death certificate. We will need to collect details of the family member, representative or executor who is acting on the deceased's behalf. We may also need to see other documents but we will let you know if this is so.

If you need to talk to us about the deceased's mortgage, please call us or make an appointment at one of our branches.

Certificate of mortgage interest (MIRAS 5) - What is it and do I need one?

What exactly is a certificate of mortgage interest?

A certificate of mortgage interest (MIRAS 5) is a certificate giving details of the interest charged to your mortgage account during the previous tax year. A certificate of mortgage interest is required by some of our mortgage customers for tax purposes.

If you need a certificate of mortgage interest, please call us or make an appointment at one of our branches.

Please note that we cannot produce a certificate of mortgage interest for tax paid until the tax year in question has ended.

Release of part security - What exactly is it?

What is a release of part security?

A release of part security is when a mortgage customer wishes to sell part of their land and/or outbuildings on that land. If you think you may want a release of part security, you will need to discuss that with us.

It is known as a release of part security because as the lender, if we agree to it, we are releasing a portion of the property forming part of our security on the mortgage. The process is often handled on the customer's behalf by a solicitor and can involve having the property valued again.

If you wish to discuss a release of part security on your mortgage with us, simply call us or make an appointment at one of our branches.
