Sending and receiving files
At the bottom of each job page is a Documents section: anything you send the installer, and anything they share with you, in one list.

Sending something
Section titled “Sending something”Press Add a file and pick it. The control says what it takes: PDFs or photos, up to 10 MB each.
Accepted file types are PDF, JPEG, PNG, WebP and HEIC, which between them cover everything a phone or a scanner produces. Nothing else is allowed through, including SVG, which is a picture format that can carry code inside it and is refused deliberately.
Things worth sending, if they ask:
- A photo of your consumer unit, the box with the trip switches in it.
- Photos of the roof from the ground, from a couple of angles.
- A recent electricity bill, or an annual statement.
- A previous quotation, if you are comparing.
Anything you upload is visible to the installer straight away. Files they upload are theirs until they choose to share one with you, at which point it appears in this list.
The limits
Section titled “The limits”| Limit | Value |
|---|---|
| Size of one file | 10 MB |
| Files on one job | 20 |
| Total on one job | 100 MB |
| Uploads in an hour | 10 |
If something is refused, the message says why: the file is empty, it is bigger than 10 MB, it is not one of the accepted types, or the job has reached its file limit and something has to be deleted first.
A phone photo is usually two to four megabytes, so the per-file limit is generous. A long PDF scanned at high resolution is the thing most likely to go over it.
Deleting
Section titled “Deleting”You can delete the files you uploaded. Files the installer shared with you are theirs, and only they can remove those.
Deleting your own upload removes it from their view too, so if they asked for a photo and you have deleted it, they no longer have it.
If there is no Add a file button
Section titled “If there is no Add a file button”Two possibilities.
You have not used a sign-in link yet. Uploading needs your email address confirmed, and the page tells you so, pointing you at the sign-in link that was sent to you. See signing in.
The installer has not set file storage up. Some have not. In that case the section is still there, listing anything that exists, but nothing can be uploaded by either side. Email them the photograph instead.
