PorthmonSell with proof. Buy with trust.

For buyers, assessors and advisers · Planned

Ask for proof. Get a pack, not a pile.

You ask farms for the same documents again and again. With Porthmon, the farmer answers your request from records they already keep, each item labelled by how strong it is, shared with you for a set time.

Planned: nothing is shared today
The farmer side works now: farms in Wales keep their records in Porthmon and can preview what you would see. Requests from buyers are being designed with a small pilot in November 2026.

What you could ask for

What you would receive

A Proof Pack: the farm, the records you asked for, each with its date, place and label, any photo or document attached, the farmer's consent and the date your access ends. Example records from the fictional sample farm:

How proof is labelled

Self-declared the farmer's own record · Evidence attached backed by a photo or document · Checked by a named person on a date

How we label proof

What it is not

Porthmon is designed to work alongside RPW Online, EIDCymru, assurance schemes and industry data exchanges, not to replace them.

Try it in November 2026

We are looking for 2 to 5 buyers or advisers in North Wales and Cheshire to send a real request to farms they already work with.
