## What happens after you send it

1. Your enquiry is checked for spam and its contact details are checked so a firm can reach you.
2. Worklanded chooses up to three off-mains sewage treatment engineers that cover the area. A firm sees the job and the area before it decides to take it.
3. As your details go to each firm, we email you its name, with a link that stops any more firms receiving them.
4. The firms contact you directly. You agree the price and the work with them; Worklanded takes no part of that.
