Rate Switch Or Remortgage?
Understand the difference between switching rate with your current lender and remortgaging to a new lender before your deal ends.
Choosing between a rate switch and remortgage depends on your current deal, lender options, costs, affordability and future plans.
Useful reminder: The lowest interest rate is not always the cheapest overall route.
Quick answer
Should you rate switch or remortgage?
A rate switch means choosing a new mortgage deal with your existing lender, usually without moving the mortgage to another provider. A remortgage means moving your mortgage to a new lender, often to access a different product, raise funds or change the mortgage structure. A rate switch can be quicker and may involve fewer checks, but it only compares your current lender’s deals. Remortgaging may offer wider choice, but can involve affordability checks, legal work, valuation and possible fees. The right option depends on rates, costs, timing, your circumstances and what you want the mortgage to do.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage.
A new deal with your current lender, often simpler but limited to that lender’s products.

Main guide
What is a rate switch?
A rate switch, also called a product transfer, is when you move onto a new mortgage deal with your existing lender. You are not usually moving the mortgage to another bank or building society. Instead, you choose from the products your current lender makes available to you.
This can be useful when your fixed, tracker or discounted deal is ending and you want to avoid moving onto the lender’s standard variable rate. A rate switch may be quicker than a full remortgage because the lender already holds your mortgage.
What is a remortgage?
A remortgage is when you move your mortgage from your current lender to a new lender. This may be done to secure a new rate, raise extra funds, change the term, adjust the mortgage structure or move to a lender with more suitable criteria.
A remortgage normally involves a new application. The lender may assess your income, outgoings, credit history, property value and mortgage requirements. There may also be legal work and a valuation.
Both options can be useful, but they should be compared properly before deciding.
Your home may be repossessed if you do not keep up repayments on your mortgage.

What should you compare?
When deciding between a rate switch and remortgage, it is important to compare the total picture, not just the interest rate. A product with a lower rate may have a higher fee, and a deal with a slightly higher rate may include useful incentives.
You may need to compare:
- monthly payments
- product fees
- valuation fees
- legal fees
- cashback or free legal incentives
- early repayment charges
- whether you need to raise extra funds
- whether your circumstances have changed
- future flexibility, such as overpayments or moving home
A rate switch may involve fewer checks, which can be helpful if your circumstances have changed and a new lender may be harder to pass. However, staying with your current lender could mean missing a better option elsewhere.
A remortgage can widen the choice of lenders, but the new lender will usually carry out affordability and credit checks. If your income, outgoings or credit profile have changed, this may affect what is available.
The best route depends on the full cost, your plans and whether the product fits what you need now.

This is a simplified comparison. Mortgage deals, fees and criteria can vary by lender and circumstance.
When a rate switch may make sense
A rate switch may suit some borrowers when the current lender has a competitive deal, the process is simple, or the borrower does not want a full remortgage application. It may also be useful if income, employment or credit circumstances have changed and switching lender could be more difficult.
Some lenders allow existing customers to secure a new deal several months before the current deal ends. The timing and rules vary, so it is worth checking early.
When a remortgage may be better
A remortgage may be worth considering if another lender offers a better overall deal, if you want to raise funds, change the mortgage term, consolidate parts of your borrowing or move to a product with features your current lender does not offer.
A remortgage may also be useful if your property value has increased and your loan-to-value has improved. This could give access to different product options, subject to lender criteria.
What if your circumstances have changed?
If your income has reduced, you have become self-employed, changed jobs, taken on new credit or had credit issues, the remortgage route may need careful planning. A new lender will usually assess affordability and credit profile again.
In some cases, a product transfer with the current lender may be simpler. In other cases, a specialist lender or different approach may be available. This is where advice can be helpful.
Avoiding the standard variable rate
If your current deal ends and you do nothing, you may move onto the lender’s standard variable rate. This can often be higher than fixed or tracker products available at the time, although rates can change.
It is sensible to review options before the deal ends. Waiting until the last minute can limit time for advice, documents, legal work and lender assessment.
Common mistakes to avoid
One common mistake is accepting the first product transfer offered without comparing it. Another is focusing only on the headline rate without checking fees and total cost.
It is also important to check whether an early repayment charge applies if you leave your current deal before it ends. Switching too early could be expensive unless the new option justifies the cost.
How The Mortgage Hive can help
The Mortgage Hive can help compare a rate switch with a full remortgage. We can review your current mortgage, remaining balance, deal end date, early repayment charges and what you want from the next mortgage.
This can help you understand whether staying with your current lender is sensible or whether a new lender may be worth considering.
Looking beyond the headline rate
A mortgage decision should not be based on the interest rate alone. Fees, incentives, legal costs, valuation, early repayment charges, flexibility and future plans can all affect which option is most suitable.
We can help explain the practical difference between the options in plain English.
Fee-free mortgage advice
The Mortgage Hive provides whole-of-market mortgage advice and does not charge a broker fee. We can compare available mortgage routes and help you understand your next step before your current deal ends.
What to do next
If your mortgage deal is ending soon, gather your current mortgage details and check when any early repayment charge finishes. Starting early gives you time to compare options properly rather than making a rushed decision.
Your home may be repossessed if you do not keep up repayments on your mortgage.

MORTGAGE-READY STEP
WHAT IS A DECISION IN PRINCIPLE?
A Decision in Principle, sometimes called an Agreement in Principle or Mortgage in Principle, is an initial indication from a lender of what they may be prepared to lend based on information provided at that stage.
It can help you understand a possible budget and show estate agents that you have started the mortgage process. It is not a full mortgage offer and can still change once the full application, documents, credit checks, valuation and underwriting are completed.

FAQs
Common rate switch and remortgage questions.
What is the difference between a rate switch and remortgage?
A rate switch usually means choosing a new product with your current lender. A remortgage means moving your mortgage to a new lender. A rate switch can be simpler, but a remortgage may give access to wider options, subject to affordability and criteria.
Is a rate switch easier than remortgaging?
It can be. A rate switch may involve fewer checks because you are staying with your existing lender. However, it only compares that lender’s deals. Remortgaging can involve more paperwork, but it may offer more choice or a better overall result.
Do I need a solicitor for a rate switch?
Usually, a straightforward rate switch with the same lender does not need the same legal work as a remortgage. A remortgage to a new lender may involve legal work, although some products include free or assisted legals. The exact process can vary.
Will I need affordability checks to remortgage?
Yes, a new lender will usually assess affordability, income, outgoings and credit profile. If your circumstances have changed, this could affect what is available. A rate switch with your current lender may involve fewer checks, but this depends on the lender.
Can I borrow more with a rate switch?
Sometimes, but extra borrowing is usually a separate request and depends on your lender’s criteria. A remortgage may also allow additional borrowing, subject to affordability, property value and purpose of funds. It is best to compare the options carefully.
When should I review my mortgage deal?
It is sensible to review your options several months before your current deal ends. This gives time to compare your current lender’s rate switch offers with remortgage options and avoid rushing before moving onto the standard variable rate.
Can The Mortgage Hive help compare rate switch and remortgage options?
Yes. The Mortgage Hive can compare your current lender’s rate switch options with wider remortgage deals. We do not charge a broker fee, and we can help explain the costs, checks and timing involved.
