Quick Answer: Mortgage Porting in Brighton & Hove
Mortgage porting in Brighton & Hove lets you transfer your existing mortgage deal to a new property instead of taking a new one. It can help you keep a lower interest rate and avoid early repayment charges, but approval isn’t guaranteed and still requires affordability and credit checks.
Always compare it with remortgaging to see which option costs less overall based on your situation in Brighton & Hove, East Sussex, UK.
What is Mortgage Porting & How Does It Work?
Mortgage porting sounds technical, but it’s actually pretty simple. It just means moving your existing mortgage deal (your interest rate and terms) from your current home to a new one when you move. So instead of starting from scratch, you carry over your current deal to the next property.
This is different from getting a brand-new mortgage, where you’d pick a new lender or product entirely. With porting, you stay with the same lender but that doesn’t mean it’s automatic. It still depends on their checks and criteria.
Lenders allow porting mainly to keep you as a customer. If you’re on a good fixed rate, especially one you secured a few years ago, they’d rather retain you than lose you to another bank. In places like Brighton & Hove, where average house prices are around £308,000 (ONS, Dec 2025), this can be a big deal because replacing your deal at today’s rates could cost more.
What Actually Gets “Ported” Is Usually
- Your current interest rate
- The remaining term of your deal
- The lender itself
But the loan amount doesn’t always match your new purchase. For example, if you’re moving from a flat in BN1 (Brighton city centre) to a larger house in BN3 (Hove), you might need to borrow more. That extra borrowing is usually offered at a new rate, which could be higher.
Don’t assume your mortgage is portable. Some deals aren’t. Always check with your lender early, ideally before you even make an offer.
How Does Porting Works?
- You contact your current lender and ask about porting
- You apply for the new property (just like a normal mortgage application)
- The lender reassesses your affordability and checks the new property
- If approved, your mortgage is transferred when you complete your move
A few key terms you’ll come across:
- Loan-to-value (LTV): How much you’re borrowing compared to the property value
- Early repayment charge (ERC): A fee if you leave your current deal early (porting can help avoid this)
- Product transfer: Switching to a new deal with the same lender
Because Brighton & Hove City Council areas include a mix of flats, period terraces, and leasehold properties, lenders may also look closely at the type of home you’re buying. Leasehold flats, for instance, can come with extra checks, and approval always varies by lender and your financial situation.
Eligibility Criteria for Porting
One of the biggest misconceptions is that mortgage porting is guaranteed. It’s not. Even if your deal is portable, you still have to go through a full mortgage application again, and approval always depends on the lender’s current criteria.
This is where many people get caught off guard, especially when moving within areas like BN1 or BN3, where property values and types can vary a lot.
Credit Checks Still Apply
Your lender will run fresh credit checks, just like they would for a new mortgage. If your credit score has dropped since you first took the deal: missed payments, higher debts, or new borrowing; it could affect your approval.
Check your credit score a few months before you plan to move. Fixing issues early can make a big difference, especially as criteria vary by lender.
Affordability Is Reassessed
Even if you’ve been paying your mortgage comfortably, lenders will reassess your income and outgoings based on today’s rules. This includes:
- Your current salary or self-employed income
- Monthly expenses and debts
- Any new financial commitments
If your situation has changed like switching jobs, becoming self-employed, or having dependents; it can impact how much you’re allowed to borrow. This is particularly relevant in higher-cost areas under Brighton & Hove City Council, where borrowing requirements are often larger.
Property Type Matters
Not all properties are treated equally. Lenders will assess the new home to make sure it fits their criteria. In Brighton & Hove, common property types include:
- Victorian terraces (generally lender-friendly)
- Regency conversions (usually fine, but leasehold terms matter)
- Modern apartments (may face stricter checks, especially high-rise blocks)
Some properties, like non-standard construction homes or very tall buildings, can be harder to mortgage. This varies by lender and policy at the time.
Loan-To-Value (LTV) Can Change
Your Loan-to-Value (LTV) ratio is recalculated based on your new property price and how much you want to borrow.
For example, moving from a £188,000 flat to a £300,000 house in Brighton means either putting in more deposit, or increasing your borrowing, which raises your LTV
A higher LTV can mean higher interest rates or stricter criteria. If you need extra borrowing, that portion is often offered on a different rate.
Common Reasons Porting Gets Declined
Porting applications can be refused for a few reasons, including:
- A drop in your credit score
- Changes in income or employment
- The new property not meeting lender criteria
- Updated lender policies since you first took the mortgage
Overall, porting approval always comes down to affordability, credit profile, and the property itself, and it can vary quite a bit depending on the lender and your circumstances.
Advantages of Porting Your Mortgage
- Keep your current rate: Great if you locked in a low rate before; can save money over time, especially as rates have changed since 2022–2024.
- Avoid early repayment charges (ERCs): These can be around 1%–5% of your loan (varies by lender), and porting usually avoids them.
- Fewer upfront fees: You may skip new arrangement or booking fees on the ported part.
- Stay with the same lender: Can feel easier since they already know your history.
For Example: On a £200,000 mortgage with a 3% ERC, leaving your deal could cost £6,000. Porting could reduce that to £0, in most cases, subject to lender criteria.
Disadvantages of Porting Mortgage
- Not guaranteed: Porting is still a full application, so approval depends on your income, credit, and the property (varies by lender).
- Extra costs still apply: You’ll likely pay for valuation and legal fees when buying.
- Limited choice: You’re stuck with your current lender, so you might miss better deals elsewhere.
- Top-up may cost more: Any extra borrowing is usually at a higher, current rate.
- Can take time: The process can be slower and more complex than expected, especially with certain property types in Brighton & Hove City Council areas.
Mortgage Porting vs. Remortgaging
When you move home, you’ve got two main choices:
- Port your mortgage: stay with your current lender, or
- Remortgage: switch to a new deal, possibly with a new lender
The right option depends on things like your current rate, early repayment charges, how much more you need to borrow, and the type of property you’re buying in areas like BN1 or BN3 under Brighton & Hove City Council (all subject to lender criteria and affordability checks).
When Is It Better to Remortgage?
Remortgaging can be the better option in a few common situations, especially in a place like BN1 or BN3 under Brighton & Hove City Council, where borrowing needs are often higher. It usually makes more sense when:
i. Your Current Deal Is Ending or Has No ERCs
If your fixed or tracker deal is about to finish, you can switch without paying early repayment charges. That gives you full flexibility to shop around for a better rate.
ii. Better Rates Are Available Elsewhere
If market rates have dropped or your financial situation has improved—you might find a cheaper deal with another lender. Even after fees, the overall cost could be lower (varies by lender and product).
iii. You Need to Borrow a Lot More
Moving to a bigger home in Brighton & Hove often means a bigger mortgage. With remortgaging, you can combine everything into one loan, instead of splitting it into your old rate + a higher-rate “top-up.”
iv. You Want More Flexibility
Remortgaging lets you:
- Change your mortgage term
- Switch to a different type: fixed, tracker, etc.
- Choose features that suit you now like overpayment options
v. Your Current Lender Isn’t Competitive Anymore
Some lenders don’t offer the best follow-on deals. Switching can open up better options across the wider market.
vi. You Want to Consolidate Debts or Restructure Finances
Some people remortgage to simplify their finances like rolling other debts into the mortgage, subject to affordability checks and risks.
| Feature | Mortgage Porting | Remortgaging |
| Interest Rate | Keep your existing rate, often lower if fixed earlier | Get a new rate based on current market |
| Early Repayment Charges (ERCs) | Usually avoided | Often payable unless your deal has ended |
| Product Choice | Limited to current lender | Full market access |
| Affordability Check | Yes, reassessed by same lender | Yes, new lender assessment |
| Additional Borrowing | Allowed, but usually at a different (higher) rate | Combined into one new mortgage |
| Fees | Valuation + legal + possible top-up fees | Valuation + legal + product fees + possible exit fees |
| Flexibility | Less flexible, tied to lender rules | More flexible, tailored to your needs |
| Speed & Process | Can be slower, tied to your move | Can be quicker if no chain, but still a full application |
The Step-by-Step Mortgage Porting Process
If you’re planning to port your mortgage while moving in areas like BN1 or BN3 under Brighton & Hove City Council, here’s how the process usually works.
1. Check with Your Lender First
Start by contacting your current lender to confirm if your mortgage is actually portable. Ask about their rules, timelines, and any conditions.
Do this early, ideally before you even list your property, so you know where you stand.
2. Sell Your Current Home
Next, put your existing property on the market and secure a buyer.
Brighton & Hove can be competitive, especially for well-located flats and terraces, so things can move quickly, or sometimes slower depending on demand.
3. Find Your New Property
Once you’ve got a buyer lined up (or are close), start house hunting and make an offer on your new place.
Popular spots like Kemptown or Poets Corner often attract strong interest, so be prepared to act fast.
4. Apply to Port Your Mortgage
Now you formally apply to port your mortgage to the new property.
Even though you’re staying with the same lender, this is still a full application. They’ll reassess your credit, income, and affordability, so approval isn’t guaranteed and depends on lender criteria.
It’s worth getting a Mortgage in Principle (MIP) at this stage for extra clarity.
5. Valuation and Legal Work
Your lender will arrange a valuation on the new property, and you’ll need to instruct a solicitor or conveyancer to handle the legal side.
If you’re buying a leasehold flat (very common in central Brighton), expect extra checks, which can slow things down a bit.
6. Receive Your Mortgage Offer
If everything checks out, your lender will issue a mortgage offer. Go through it carefully, especially if you’re borrowing more, as the extra amount may be on a different rate.
7. Exchange and Complete
Finally, you’ll exchange contracts and complete both the sale of your old home and the purchase of the new one.
Timing is really important here. In most cases, both transactions need to line up closely, although gaps can happen and need careful planning.
Costs Involved in Porting
Porting can save you money, but it’s not free. A lot of people focus only on the interest rate and forget about the extra costs that come with moving, especially in areas under Brighton & Hove City Council.
Below is a simple overview of what you can expect:
- Valuation fee: Your lender will check the value of the new property. This usually costs a few hundred pounds.
- Legal / conveyancing fees: You’ll pay a solicitor for the buying process. In Brighton & Hove, this is often around £1,000–£1,500+ depending on the property and complexity, e.g. leasehold flats.
- Product fees: If you take extra borrowing, that part may come with its own fee and rate.
- Early repayment charges (ERCs): If porting doesn’t work out and you switch deals, you could still face ERCs, often 1%–5% of the loan, depending upon the lender.
- Broker fees (optional): If you use a mortgage broker, which can help, they may charge a fee.
Other moving costs to keep in mind:
- Stamp Duty Land Tax (SDLT): Depends on property price and your situation
- Survey costs: Optional but recommended
- Removals and moving expenses
