My DP and I lost our jobs in first lockdown. We both managed to get new jobs doing the same job role, but at lower levels / less pay.
We signed up to Deliveroo and delivered by car. We had a tracker app, so we could find each other and park up side by side in quiet periods while waiting for a job.
I quite enjoyed it. I soon learned which restaurants / takeaways / estates to avoid / reject jobs for and loved it when I got a groceries pick up as they were quick jobs and we were paid per job and not per hour.
When it was quiet, you could earn as little as £6ph (not deducting fuel costs), but I was usually parked up reading a book, or watching stuff on my phone. When it's busy, they'd boost the job pay to 1.5, or double, so a £6 job would be a £9 job, or a £12 job. You'd also pick up two orders per job in busy periods and on some good days I'd get £25-£30 an hour (it's rare to get that much though).
Working in the dark was difficult, Google maps or anything similar rarely took you to the exact house and 70% of houses didn't have very visible house numbers.
Majority of customers were nice (only 20% of them tip) and most staff at outlets were efficient and friendly, but the fast food places speak to and treat drivers like shit.
In a typical week, I'd go out for an hour or two after work, then a few hours Saturday and again on Sunday and typically earned £200 a week, paid into my account every Tuesday.
It certainly kept our head above water and was a godsend.
Be mindful, you have purchase extra insurance (Hire and Reward) if using a vehicle, mine worked out 80p ph and the app linked up to Roo app, so I was only charged when I was on a job.
You also have to sort your own tax. Fuel is ridiculous obviously, Although your fuel is of course, tax deductible.
We are both back earning what we previously were, so don't do Roo anymore. But, I had a sudden bill to pay last year and just launched app, went out that weekend and earned the money to cover it. So it's good to have that as a back up.
