The widgets are now available via DevUpNorth or Estate Agent Widgets.
They are all updated with the latest 2024 Autumn Budget announcements.
If you are using or are interested in the WordPress plugins, then these are now available on my website at DevUpNorth:
Stamp Duty Calculator
Wales Land Transaction Tax Calculator
Mortgage Calculator
If you used the non-WP hosted version of the widgets, then you’ll need to sign up for a subscription at Estate Agent Widgets.
