Your current lender may offer you a quick and easy mortgage switch. But is it the right deal for your circumstances? Before clicking ‘accept’, here’s why getting professional mortgage advice could make all the difference.
If your mortgage deal is coming to an end, there is a good chance your lender will be in touch with an offer to stay.
It might promise a straightforward switch, minimal paperwork and a new interest rate at the click of a button.
For busy homeowners, that convenience can be tempting. After all, why go through the process of comparing mortgages when your existing lender is offering a simple solution?
But convenience and value are not always the same thing.
Your mortgage is likely to be one of your biggest financial commitments, and the deal you choose could affect your household finances for years to come.
Before automatically accepting your lender’s offer, it could be worth speaking to a mortgage broker to find out whether staying put or switching elsewhere is the better option for you.
The easy option: staying with your current lender
When your existing mortgage deal expires, your lender may offer you a product transfer.
This simply means moving onto a new mortgage product with the same lender, rather than switching to another provider1.
For many homeowners, this can be a relatively straightforward process. Depending on your circumstances, there may be no need for a new property valuation, legal work or a full affordability assessment2.
There may also be fewer fees involved, making it an attractive option for borrowers who want a simple transition1.
But there is something important to consider.
Your lender will generally only show you the mortgage products it has available, rather than comparing what other lenders might be prepared to offer1.
That means you could miss a potentially more suitable deal elsewhere.
A mortgage broker can review your existing lender’s offer alongside other available options, helping you understand whether the convenience of staying put represents good value.
And importantly, if remaining with your current lender is the most appropriate choice, a broker can explain why.
Good mortgage advice is not always about changing lender. Sometimes it is about making sure you have a sound reason to stay.
Could switching lenders save you money?
The alternative to a product transfer is remortgaging1.
This involves replacing your existing mortgage with a new deal from a different lender1.
It can require more paperwork, a fresh affordability assessment, a valuation and legal work1.
However, moving lenders could give you access to products that better suit your financial circumstances or offer lower overall borrowing costs.
For example, if your property’s value has increased or you have reduced your outstanding mortgage balance, your loan-to-value ratio may have improved.
This could make you eligible for different mortgage deals, although lenders will still assess your individual circumstances and affordability.
A broker can help you understand how your current financial position affects the options available, rather than simply comparing the rates you see advertised online2.
They can also consider whether features such as overpayment allowances, flexibility or the ability to move your mortgage to another property are important to you.
Of course, remortgaging is not guaranteed to save money. Fees, eligibility requirements and the terms of your existing mortgage all need to be considered.
This is where getting advice can be valuable: understanding not just which deals are available, but which may be suitable for your circumstances.
Why the cheapest-looking mortgage may cost you more
When comparing mortgages, it is natural to focus on the headline interest rate.
But the lowest rate does not necessarily mean the lowest overall cost3.
Some products come with significant arrangement fees, while others may offer a slightly higher rate with lower upfront charges3.
You might also face valuation costs, legal fees or early repayment charges, depending on the mortgage and your circumstances3.
And if you add a product fee to your mortgage balance, you could end up paying interest on that fee3.
A mortgage broker can help you look beyond the headline figures and compare the overall costs of suitable deals over a relevant period.
That can be particularly useful when deciding between a product transfer and moving to a different lender.
A lower interest rate may look attractive at first glance, but once fees and other costs are factored in, the difference may be smaller than you expected.
In some circumstances, a deal with a higher interest rate could work out cheaper over the period you intend to keep it.
The real value of advice is understanding what a mortgage will cost you, not simply what rate is advertised.
Your circumstances have changed. Has your mortgage kept up?
A lot can happen during a two-year or five-year mortgage deal.
You might have received a pay rise, changed jobs, started a family, become self-employed or built up more equity in your home.
Perhaps you are planning home improvements, thinking about moving or considering how to reduce your monthly outgoings.
These changes can affect which mortgage products may be suitable.
For example, extending your mortgage term could potentially reduce your monthly repayments, although it would usually increase the total interest paid over the life of the mortgage4.
Alternatively, shortening your mortgage term may help reduce total interest costs, but would generally increase your monthly repayments4.
A mortgage broker can help you explore these trade-offs and understand how different options align with your financial plans.
They can also identify potential restrictions, such as early repayment charges or limits on overpayments, that may matter if your circumstances change again.
Rather than looking at your mortgage as an isolated product, professional advice can help you consider how it fits into your wider financial position.
Why reviewing your mortgage early matters
If your existing mortgage deal is due to end within the next six months, it may be worth speaking to your mortgage broker now.
Many lenders allow borrowers to secure a new mortgage deal several months before their existing arrangement expires, although the timescales vary2.
Starting early can give you more time to review the options available, understand the costs and complete any necessary applications.
It may also help you avoid moving unintentionally onto your lender’s standard variable rate when your current deal ends.
Standard variable rates are often higher than the rates available on new mortgage deals, although this is not always the case3.
Mortgage rates can also change while you are considering your options.
A broker can explain how long an available mortgage offer may remain valid and whether there is an opportunity to review the deal again before completion.
This can be particularly helpful when deciding whether to secure an available product now or consider alternatives as your existing deal approaches its end.
While no adviser can predict future mortgage rates, getting advice early gives you time to make a considered decision rather than having to rush.
Five questions worth asking your mortgage broker
Before committing to your next mortgage deal, consider discussing these questions with your adviser:
- Is my existing lender offering me a competitive deal? Ask how its product transfer options compare with suitable alternatives from other lenders.
- Would switching lenders be worthwhile after fees? Understanding the total costs can help you assess whether moving would provide a financial benefit.
- Has my loan-to-value ratio improved? Changes to your property’s value and outstanding mortgage balance could affect the deals available to you.
- Could a different mortgage structure better suit my plans? Discuss your preferred term, repayment arrangements and any flexibility you may need.
- When should I secure my next mortgage deal? Your broker can explain the available timescales and help you plan ahead.
You do not need to have decided whether you want to stay or switch before speaking to an adviser. Exploring those options is part of the advice process.
Before you click ‘accept’, speak to your mortgage broker
Accepting a product transfer directly from your current lender may seem like the quickest and simplest solution.
And for some homeowners, staying with their existing provider will be entirely appropriate.
But your lender’s offer is only one part of the picture.
A mortgage broker can help you compare suitable options, understand the true costs, navigate lender requirements and consider how your mortgage fits with your financial plans.
Most importantly, they can provide a personal recommendation based on your circumstances rather than leaving you to make the decision based on an advertised rate alone.
Your mortgage is too important to choose purely for convenience. Getting professional advice could help you make a more informed decision.
