i called up rhb to enquire about reno loan few days back and this is what i was told 
1) max 3 companies  
- for eg: hdb approved contractor + plumbing works + electrical works 
- as long as plumbing or electrical works company is a registered company, the bank will issue the cheque 
- bank will not issue to freelance  
2) quotations must be provided when applying loan 
3) cheque will be issued upon customer request 
- 1st cheque is free 
- subsequent cheque is $8 / cheque 
hope this helps
