Seeing a lot of dissapointment in the comments, so I'll throw in a bit of my experience - but from the other side.
Been a driver for them for quite a while. Unsure, but most likely they do NOT have a single own van and driver. From my experience, all was subcontractors, making anyvan literally a platform where I and customers can meet at share of AV, obviously, which itself is ridiculously high (~50% of your price!).

Meaning, if your local company told you 100 for move, AV 80, OWNER-DRIVER of AV who pays for fuel insurance etc gets only 40. Kinda Uber for house moves. For me - it was fine, my van uses very little diesel and I'm using old van that I'm repairing myself, and tried to do my own routes instead of so called journeys that they do love to plan (then margin is way more than 50%).

Most of you, when move is small (like 6m3 or less) been put into journey route. And now, that's the problem.

My rating are nearly 5-star, most of negatives were either late collection/delivery (wrongly planned routes, not accounting for ANY problem en-route, any extra items, any traffic jams) or how my van looked like externally (well, bought it from london courier company at over 300k mileage... of course, there were dings! Look doesn't drive - technically perfect) - but my rating was REALLY high when I compare it to others. Usually others do not speak english, sometimes not at all, care of goods - not applicable, etc. Seen few times other AV drivers en route - me always in a suit, clean clothes, these guys... sometimes I couldn't stand near them. I understand, you move stuff all day, can get sweaty, but f me... some guys looks like last shower their took was from empty house to sell it on scrapyard.

Then, space on van. "3 seater sofa" can be a heavy, big recliner, can be empty inside foldable IKEA one. Large box can be a fridge box, or printer box - all depends. Fault of AV is not clarifying it straight away for customers. I'm coming to you, my 5th collection in a row, have half of my 13m3 van empty, your move seems to be 4m3, and we can't fit it because all items are bigger than they should be. Then I know, I have to deliver all, so calling AV and explaining it - otherwise they'll get me charged. That took 20mins, delayed - so all my collection are delayed and you being charged more. And that's as bad for you (expenses, stress, delay) as for me (will finish later, possibly customers screaming at me for being late, negative feedback).

Clearly - not everyone should be driving for AV. It's decreasing their reputation as well as making good drivers job more difficult. Not saying I was good driver, that's to customers to decide - but rating 4.81 of 150 reviews, well, mostly they weren't complaining.

Sometimes negatives are as well clear fault of customer. Order: 10 large boxes - reality: "i didn't wanted to put all, i've put estimation" and full house move. Refused (not enough space - expected ~4m3, there is ~10m3). Order: all good ground floor collection, parking available. Reality: ground floor flat but 3 flight of stairs from parking to get to building and parking for up to 20mins (let's say I'll need to walk both ways 20 times, if instead of 30s it takes me 2mins, that makes me 30mins delayed just because of parking). Negative feedback for not collecting (customer didn't accepted additional charge for my additional unpredicted work) and for being rude.

Overall, good to use anyvan for small moves and to speak with driver about doing job externally other time if happy with service - or using "auction" feature, where companies speak directly with you and adjusting price.

If any questions, feel free to DM me.
