Yes. Every series behind this site is downloadable as CSV and JSON under CC BY 4.0, which lets you republish it, including commercially, as long as you credit Tekstak Ltd and link back. Files are regenerated on every nightly run, so a link stays current. There is also an embeddable widget that updates itself.

Licence and attribution
Published under CC BY 4.0. Please credit Tekstak Ltd with a link to the page you took the figure from. A suggested form:
Source: Where your money goes (Tekstak Ltd), whereyourmoneygoes.co.uk
The underlying data is Crown copyright or the copyright of the publishing body — DESNZ, HMRC, Ofgem, the ONS, the Bank of England, Eurostat, the European Commission, the St. Louis Fed — and is used under their own terms. Each series file names its source so you can go back to it.
When the files update
The pipeline runs at 02:00 UTC every night. Files only change when the data does, so a quiet night leaves no diff. Each source publishes on its own schedule: DESNZ pump prices weekly on a Monday or Tuesday, Brent and the exchange rate daily on working days, Ofgem quarterly, the IEA comparison tables annually and about two years in arrears. The status page shows what happened last night.
Embedding a live figure
Every page has an embeddable widget showing that page's headline figure. Paste the iframe from the "use this data" box at the bottom of the page. The widget is a static HTML file regenerated on every run, sets no cookies, loads no scripts from anywhere else, and links back to the page it came from.
