Add our free property tax calculators to your site
Free, mobile-friendly and always kept current with UK tax rates. If you advise or write for landlords and property investors, drop any of these into your own pages with a single line of HTML. We keep them up to date; you keep your readers on your site.
Built for mortgage brokers, conveyancers, letting and estate agents, and buy-to-let blogs. The only condition is that you leave the small “Powered by Property Tax Partners” line in place.
How to embed (2 steps)
- 1. Paste the calculator. Copy the iframe snippet for the calculator you want and paste it into your page where you want it to appear.
- 2. Add the resize script once. Paste the small script below anywhere on the same page. It lets each calculator grow or shrink to fit its content, so there is no awkward scrollbar.
<!-- Add once, anywhere on the page. Lets the calculators resize to fit. -->
<script>
window.addEventListener("message", function (e) {
if (e.data && e.data.type === "ptp-embed-height") {
document
.querySelectorAll('iframe[src*="propertytaxpartners.co.uk/embed/"]')
.forEach(function (f) { f.style.height = e.data.height + "px"; });
}
