Public registers,
made usable.

Government publishes an enormous amount of data for re-use, and almost none of it arrives in a form anyone can work from. We compile it, filter it to the people it concerns, and refresh it every month.

What we publish

One dataset, done properly.

We take on a register only after reading its licence in full and establishing what may lawfully be built from it. That is slower than the alternative, and it is why our files can be used without argument.

Dataset 01

EPC & MEES — England & Wales

Private rental properties whose latest Energy Performance Certificate signals legally-driven improvement work, filtered by region and packaged for the trade that acts on it. Compiled from the register published by MHCLG.

How we work

Three commitments that hold on every file we send.

Sourced from public registers

Every product is compiled from data government publishes for re-use. We name the source and the publication date on every file, so you can check us against it.

Refreshed on a schedule

Data ages, and stale data is worse than none. Ours is rebuilt monthly from the current release, and each file states the exact period it covers.

Licensed and attributed

Public does not mean unrestricted. Required copyright and attribution notices travel with every file, and permitted-use conditions are passed to customers in writing.
