Removal of embankment

You need some lad who has got a digger to remove it and some skip to take this out of your garden. Should be the best way.

Landscaper or groundworks company both can carry these works out

You will need someone within the construction trade which has excavators to dig back the embankment and get rid of the soil also depending how far you want to dig back you may need a retaining wall built

Yes you need someone with a machine , but it would need planning and organising for safety . A skip is no good but a grab lorry would work out cheaper anyway. In either case you will need a few people with wheelbarrows or a dumper depending on access , potentially a retaining wall will need building also . It all depends on what the purpose of the project is. This needs to be done under strict guidance and will not be cheep . Good luck Steve morley hardscape

Be happy to help you would need a landscaper with the correct equipment

I’ll be your best help need digger and dumper access and space for a grab load to be left. Thanks Ricky. Four seasons landscaping ltd.

First go to your local authority, as you may need planning permission. Most landscaping and groundwork companies will be able to do this. Digger, muckaway/grab hire highly advised. Skip is possible but much more costly. If I understand you correctly, and you want to leave in the remaining 20ft up till the 50ft, a retaining wall will be needed.
