Is it really free to embed these calculators?

Yes. Embedding is free for commercial and non-commercial websites. The only condition is that you keep the attribution link below the calculator so your visitors can find the source.

Do the embedded calculators stay up to date?

Always. The iframe loads the live version of each tool, so every rate and threshold updates automatically when HMRC figures change for the new tax year. You never need to update your page.

Will an embed slow my website down?

No. Each widget runs in its own iframe with lazy loading, so it does not load until a visitor scrolls near it, and none of our code affects your page's scripts or styles.

Can I remove or change the attribution link?

No. Attribution is what keeps the embed free. If you need a white-label licence for an accountant practice, payroll bureau or software product, contact us and we will quote for it.
