Frequently asked questions
Where does the price cap figure come from?
The widget uses PowerGuardian's Ofgem-based price cap tracking. It reflects the current cap period and updates automatically with our daily data refresh, so the embed always shows the latest figure without you touching the code.
Does the widget show the previous cap and the change?
Yes. It displays the current cap alongside the previous cap and the percentage increase or decrease, so your readers can see the direction of travel at a glance.
Is this widget free to use?
Yes. It's free for non-commercial and editorial use on UK consumer websites, blogs, local authority pages, housing association sites and charities. The only requirement is that the 'Powered by PowerGuardian' attribution link stays visible and clickable.
How do I add it to my website?
Copy the iframe snippet on this page and paste it into your page's HTML where you want the widget to appear. It works in any CMS that allows custom HTML or embed blocks — WordPress, Squarespace, Wix, Ghost and more.
Does it work on mobile and in dark mode?
Yes. The widget is fully responsive, mobile-optimised and lazy-loaded, and it adapts to light and dark backgrounds so it blends with your site's theme.
