Possibly although it is frowned upon by the 'I'm the best in the world everyone else is rubbish brigade' which exists within all trades 
Have you got any pics?
I would probably take those slabs up especially if the bed is sand.
One thing to make certain is that when you infill you compact the layers of sub base in approx 50mm layers, compact each layer several times. For the cost of that (time) it's worth doing and we do it on every single job. They never sink.

What you can’t see in this picture is the wall along the edge of the patio as it’s covered in soil. There were two walls with soil in between them. By plan is to keep the inner one, rebuild the outer one and probably fill the gap with concrete and put slabs over the top.Have you got any pics?

My original plan was to leave the existing slabs and put type 1 on top. I then lifted some in the corner by the house and found they appear to be laid on sand, so I thought I’d lift them all. Having demolished part of the wall, I was feeling lazy again so thought maybe I could just leave them.
Looks like I will stop being lazy!

Will raising it that much breach the house dpc ?
Looking at the air brick there are 4 courses of bricks from the patio to the dpc (thought he patio doors are very close to the dpc and possibly below it? I can't quite tell from the photo)Edited by The Gauge on Monday 10th March 08:33

The patio doors are on top of the DPC and always have been - well in the 20 years we have owned the house.The new patio level may not comply with building regs but will be at least 1 brick level below the DPC and probably more. The patio will also slope away from the house and I may put some form of drainage channel between the house and patio.
There will be a significantly greater depth difference that it turns out the next door have left when they did their side path and drive. Leaving about 10mm between our DPC and their drive!
A couple of reasons for raising the patio
It is currently split level and I want it all the same level. I also want to get reduce significantly the step out of the patio doors. Ideally I’d like to get rid of the additional step altogether but may need a much shallower one.
