You'll be better off checking campervan forums - plenty of advice there on how to do the conversion itself and what's necessary to qualify as a motorhome.

Found a page on the DVLA website:

https://www.gov.uk/government/publications/registering-a-diy-caravan/converting-a-vehicle-into-a-motorhome

Bear in mind the following bit on the above page:

It will do no harm to send DVLA the completed engineer’s report that insurers require with your photographs and V5C. Your covering letter should explain that you have completed the conversion of a van into a ‘motor caravan’ and that you are now seeking to have your V5C amended. Make it clear in this letter that you understand the requirements and list what your vehicle has ie permanently and securely fixed.

I'm assuming the reason you want to register it as a campervan is to get car speed limits (subject to it being the correct weight). Bear in mind that even when re-registered, if you use it as a van then the van speed limits still apply. Explained below:

Motorhomes or motor caravans are classed as goods vehicles if they:

• carry goods for exhibition and sale
• are used as a workshop
• are used for storage
