Two things, and neither costs anything

The latest full invoice for each meter, and a signed Letter of Authority. Sign it online, or print the template, sign it and send it back here.

Sign your Letter of Authority

Complete and sign the authority below. The wording matches the limited scope described above, and a copy is returned to you once it is signed.

Recommended on mobile: the full-screen tab gives the document more room and avoids cramped in-page scrolling.

Loading the signing form. On a slow connection this can take up to half a minute.

The widget is provided by Signable. If it does not load, please email hello@askomnium.co.uk and we will send the document directly.

Prefer to print and sign

Download the template, sign it, then send it back here. It carries the same limited wording as the online form. We check the document and confirm the sites it covers before anything is requested from a supplier.

One site per line, with the supply number where you have it. The authority applies only to the sites it names.

A scan or a clear photograph of every signed page. PDF, Word document or image, up to 15 MB each and 5 files in total.
