Copy-Paste Snippet
Paste this wherever you want the calculator to appear. It's a plain iframe with no tracking beyond what your own site already loads.
<iframe src="https://checkstampduty.co.uk/widget/" style="width:100%;border:none;" height="620" id="csd-widget" title="Stamp Duty Calculator"></iframe>
<script>
window.addEventListener('message', function (e) {
if (e.data && e.data.checkStampDutyWidgetHeight) {
document.getElementById('csd-widget').style.height = e.data.checkStampDutyWidgetHeight + 'px';
}
});
</script>
Why Embed It
Give visitors an instant SDLT/LBTT/LTT figure without sending them to a third-party site. The widget covers England/NI, Scotland and Wales, first-time-buyer relief, and second-home/buy-to-let surcharges — same calculation engine as the full calculator.
Free to use, no attribution required. If you'd like a co-branded or white-label version, get in touch via the contact details in the site footer.
