One of the most common questions we hear from clients sits right at the start of the buying journey: "How much is the stamp duty going to be?" It's a fair question, because stamp duty is one of the larger upfront costs of moving, it has to be found in cash, and it can't usually be added to your mortgage. Yet a surprising number of buyers only work it out properly once they're well into the process.

So we've made it simpler. We've added a free stamp duty calculator to the website. Pop in the property price, tell it where you're buying and what kind of buyer you are, and it gives you a clear figure straight away, along with a band-by-band breakdown so you can see exactly how the total is built up. There are no personal details to enter. Just the numbers that matter.

Why stamp duty catches people out

Stamp duty isn't one flat tax across the UK. The name and the rules change depending on which nation you're buying in. In England and Northern Ireland it's Stamp Duty Land Tax. In Scotland it's Land and Buildings Transaction Tax, and in Wales it's Land Transaction Tax. Each has its own thresholds and rates, which is exactly why the calculator asks where you're buying before it works anything out.

The other thing that trips people up is how the tax is charged. It works in bands, much like income tax. You don't pay a single rate on the whole price. Instead, each slice of the price is taxed at the rate for its band. That's good news, because it means your effective rate is almost always lower than the headline percentage you might see quoted.

The current rules at a glance

In England and Northern Ireland, the thresholds that took effect in April 2025 are still in place for 2026, with no changes announced. For a standard home purchase, you pay nothing on the first £125,000, then 2% up to £250,000, then 5% up to £925,000, with higher rates above that.

If you're a first-time buyer, you get a helpful break. You pay no stamp duty on the first £300,000, then 5% on the portion between £300,001 and £500,000. One important catch: if the price tips over £500,000, the relief disappears completely and you fall back onto the standard rates. That £500,000 line is a genuine cliff edge, so if your purchase is hovering close to it, it's well worth understanding the numbers before you make an offer.

Buying an additional property, such as a second home or a buy-to-let, adds a 5% surcharge on top of every band in England and Northern Ireland. Scotland and Wales apply their own, different surcharges, which the calculator handles for you.

Where a calculator ends and advice begins

The calculator is a brilliant starting point for budgeting, and for most buyers it gives a figure you can plan around with confidence. What it can't do is account for the trickier situations, things like replacing a main home you haven't sold yet, shared ownership, mixed-use property or linked purchases. Those are exactly the details that can change your bill, and they're the kind of thing we check with you properly.

Stamp duty is also only one line in the cost of moving. The real value comes from looking at it alongside your deposit, your mortgage and the rest of your buying costs, so you have a complete picture rather than a series of separate numbers. As independent advisers with access to 90+ lenders, that's the part we're here for: turning a pile of estimates into a plan you can actually move forward with.
