Quick Answer: Stamp Duty and Mortgages in Shoreham-by-Sea
If you’re buying in Shoreham-by-Sea, you can sometimes add stamp duty to your mortgage, but it depends on the lender and your affordability. It’s not guaranteed and may increase your loan-to-value (LTV), monthly payments, and overall interest costs. Many buyers choose to pay stamp duty upfront if possible to avoid paying interest on it over time.
Understanding Stamp Duty Land Tax (SDLT) in the UK
If you’re buying a property in England, you’ll almost always come across Stamp Duty Land Tax (SDLT). In simple terms, it’s a tax you pay when the purchase price goes above a certain threshold.
Think of it as a standard part of buying a home, just like legal fees or surveys. SDLT has been around in different forms for years and is now a key source of income for the UK government. The important thing to remember is that you, as the buyer, are responsible for paying it, not the seller.
The payment process is usually straightforward. Your solicitor or conveyancer handles it for you and makes sure it’s paid to HM Revenue & Customs within 14 days of completing the purchase.
Rules, thresholds, and reliefs can change from time to time, so it’s always best to check the latest guidance from HMRC or speak to a professional, especially if your situation is a bit more complex like buying a second home or investing.
Current SDLT Rates & Bands for UK Homebuyers
Stamp duty can feel confusing at first, but it’s actually pretty simple once you break it down. It works in chunks (bands), so you only pay each rate on the part of the price that falls into that band, not the whole amount.
Based on the latest rules from HM Revenue & Customs (updated after April 2025 changes and still in place in early 2026), here’s how it works:
Standard Stamp Duty Rates (Main Home)
- Up to £125,000 → 0%
- £125,001 to £250,000 → 2%
- £250,001 to £925,000 → 5%
- £925,001 to £1.5 million → 10%
- Above £1.5 million → 12%
(HMRC / MoneyHelper guidance, updated 2025–2026)
If you buy a home for £300,000, you don’t pay 5% on the whole amount, only on the part above £250,000. So your bill would be roughly £5,000.
First-Time Buyer Relief
If you’re buying your first home, you get a bit of a break but it’s more limited now than before:
- 0% up to £300,000
- 5% on £300,001 to £500,000
- No relief if property is over £500,000 (MoneyHelper, 2025-26)
For example, buying at £400,000? You’ll only pay 5% on £100,000 → £5,000 total.
Extra Charges to Watch Out For
- Second home / buy-to-let → typically +5% surcharge on top of normal rates (since April 2025 changes).
- Non-UK residents → extra +2% surcharge on top of everything else.
For example, buying a £300,000 buy-to-let? Your SDLT could jump from around £5,000 to £20,000.
Shoreham-by-Sea Examples
To make this a bit more practical, let’s take Shoreham-by-Sea (BN43), which falls under Adur District Council. In this area, property prices typically sit between £380,000 and £450,000 depending on the type (based on UK House Price Index trends, 2025–2026).
You’ll commonly find Victorian terraces, riverside flats, and 1930s semi-detached homes, especially around the harbour and town centre. Flats in postcodes like BN43 5–7 often range from £250,000 to £350,000, which means many buyers still fall into the 5% SDLT band.
So, in real terms, if you’re buying a typical home here for around £400,000, a standard buyer might pay roughly £7,500 in stamp duty, while a first-time buyer could pay closer to £5,000, depending on eligibility for relief.
That said, what you actually pay can vary based on your situation, like whether you’re buying jointly, already own property, or your residency status. And if you’re thinking about adding stamp duty to your mortgage, just keep in mind this isn’t guaranteed, it depends on the lender and whether you meet their affordability and lending criteria.
Can You Add Stamp Duty to Your Mortgage?
Short answer; sometimes, yes… but not always. Most lenders in the UK don’t openly advertise this, and whether it’s allowed really depends on the lender, your deposit, and affordability checks.
In simple terms, when you try to add stamp duty to your mortgage, you’re asking to borrow a bit extra on top of the property price. That pushes up your total loan, and this is where things get tricky. Lenders look closely at your loan-to-value (LTV), which is basically how much you’re borrowing compared to the property value.
If adding stamp duty pushes you into a higher LTV band (say from 85% to 90%), you might face higher interest rates or fewer deals. In some cases, the lender may simply say no.
From what most UK lenders do (based on typical market practices in 2025–2026), a few may allow it if you’ve got a strong deposit or extra equity, but many prefer that stamp duty is paid upfront. Even when it is allowed, it’s often tied to specific mortgage products, stricter affordability checks, or slightly higher rates. So it’s not a guaranteed option; it varies by lender and your personal situation.
How It Actually Works in Practice
If a lender does allow it, the process is pretty straightforward. The stamp duty amount just gets added onto your total mortgage. So instead of borrowing, say, £400,000 for a property in Shoreham-by-Sea, you might end up borrowing £407,500, including an estimated SDLT bill.
That might not sound like a huge difference at first, but it has a knock-on effect. A bigger loan means higher monthly repayments, and more importantly, you’ll be paying interest on that extra amount for the entire mortgage term (which could be 25–30 years). Over time, that can add up to thousands in extra interest, depending on your rate.
Mortgage advisors in the UK often point out that while this option can help with upfront affordability, it can make things more expensive in the long run. Plus, lenders will still check whether you can comfortably afford the higher repayments, so approval is always subject to affordability and criteria.
Pros and Cons of Adding Stamp Duty to Your Mortgage
Let’s be honest, adding stamp duty to your mortgage can feel like a handy shortcut, especially when cash is tight. But like most things in property, there’s a trade-off.
Why Some Buyers Do It
The biggest benefit is keeping more cash in your pocket upfront. Buying a home already comes with loads of costs: deposit, legal fees, moving, maybe even some quick renovations. So instead of draining your savings, rolling stamp duty into the mortgage can help you keep an emergency fund or spend on things like fixing up the property.
It can also make buying possible for some people. If you’re a bit short on upfront funds, this option might help you get onto the property ladder sooner, especially in places like Shoreham-by-Sea where prices are not exactly cheap.
Another small plus, everything gets bundled into one monthly payment, which some people find easier to manage.
Even if you plan to add it to the mortgage, always include stamp duty in your initial budget planning so there are no surprises later.
The Downsides
The main catch? You’ll pay interest on your stamp duty for years.
Let’s say your stamp duty is around £7,500 on a typical Shoreham property. If you add that to a 25–30 year mortgage, you’re not just paying £7,500, you could end up paying £12,000–£15,000+ in total depending on your interest rate (based on typical UK mortgage rates around 4–6% in 2025–2026).
That’s the real cost most people don’t think about. Your monthly payments will also be slightly higher, since you’re borrowing more. It might not feel like a huge jump, but over time it affects your disposable income and overall affordability.
There’s also a knock-on effect:
- A bigger loan can reduce how much you can borrow in the future
- It might push you into a higher loan-to-value (LTV) bracket
- And that could mean higher interest rates or fewer mortgage deals
Other Ways to Pay Your Stamp Duty
If adding stamp duty to your mortgage doesn’t feel right, there are a few other ways to cover it; some safer than others.
Using Your Own Savings
This is the most straightforward and usually the cheapest option. You just pay the stamp duty upfront from your savings.
- Pros: No interest, keeps your mortgage smaller
- Cons: Can eat into your emergency fund or delay your purchase if you’re short
Before adding SDLT to your mortgage, check all your savings options or even consider a gifted deposit from family with proper legal advice.
Gifted Money from Family
A lot of buyers, especially first-timers, get help from family. This is known as a gifted deposit, and it can also be used for stamp duty.
- Pros: No interest, reduces your upfront pressure
- Cons: Lenders will check the source, and you’ll usually need a signed gifted letter
It’s quite common in areas like Shoreham-by-Sea, where prices can stretch first-time buyers.
Loans or Credit Cards
You can use a personal loan or even a credit card to cover stamp duty, but this is usually not recommended.
- Pros: Quick access to cash
- Cons: High interest rates, extra debt, and can affect mortgage approval
There’s no one-size-fits-all solution. The best option depends on your finances, but in most cases, paying upfront (if you can) will save you money in the long run.
Navigating the SDLT Payment Process
Your Conveyancer’s Role
Your solicitor or conveyancer basically handles everything for you when it comes to stamp duty. They’ll work out exactly how much you owe, submit the paperwork to HM Revenue & Customs, and make the payment on your behalf.
All you need to do is make sure the funds are ready, either from your savings or arranged through your mortgage (if your lender allows it).
Always double-check the figures with your conveyancer to avoid mistakes or delays.
Key Deadline to Know
You’ve got 14 days after completion to get everything filed and paid. Miss this, and you could face penalties or interest charges, so timing really matters.
Simple Step-by-Step Checklist
- Confirm the amount: Your conveyancer tells you the exact SDLT due
- Decide how to pay: Savings, gifted money, or (if allowed) via mortgage
- Send the funds: Transfer money to your conveyancer
- They file the return: Submitted to HMRC
- They pay the tax: Done on your behalf
- Get confirmation: You receive proof (SDLT certificate)

FAQs
1. Can I add stamp duty to my mortgage when buying in Shoreham-by-Sea?
Sometimes, but not always. It depends on the lender’s policy and your affordability. In Shoreham-by-Sea, like elsewhere in the UK, most lenders will only allow this in specific cases and may require strong income, good credit, and sufficient equity.
2. Can I get a mortgage for 100% of the property price plus stamp duty?
Very unlikely. Most lenders won’t offer 100% LTV plus additional borrowing for stamp duty. You’ll usually need a deposit, and adding SDLT would increase your total borrowing, which can affect approval.
3. If I add stamp duty to my mortgage, will my monthly payments increase?
Yes. Since you’re borrowing more, your monthly repayments will go up slightly. You’ll also pay interest on the stamp duty amount over the full mortgage term, which increases the overall cost.
4. Does adding stamp duty affect my mortgage interest rate?
It can. If adding SDLT pushes you into a higher loan-to-value (LTV) band, lenders may offer higher interest rates. This varies by lender and product.
5. What happens if I move home after adding stamp duty to my mortgage?
You would have already paid interest on the stamp duty portion during the time you held the mortgage. The total cost depends on how long you stayed and the interest rate applied.
