A 17th Edition dual RCD board must be fitted in order to comply with BS7671:2008. If not RCD's are fitted then the work can't be signed off as compliant. It must be compliant in order to register the job with the local authority under part P of the building regulations. So you should get two certificates at the end of the job. 1) the EIC issued directly by the electrician and 2) the Part P building regulation compliance certificate issued by building control.
Note: if the work is not registered then you can be held liable as the property owner for a fine for up to £5000. So its very important that you get the part P certificate.

Your electrician should notify building control through the part P accreditation ,they should leave you with an installation cert with the test results attached ,there certified body [nic eic ,napit etc]will send the buildings owner the cert .The quick way to tell between 16th &17th edision consumer units is 16 th generally has 1 rcd and 17 th has 2 .
hope this helps

The electrician should be fitting a 17th edition split load mains board with RCD protection or a full board RCBOs depending on the electricians preference, If the electrician is a NICEIC/Napit/Elecsa registered electrician and provides you with certification of the work completed. If he is changing the consumer unit he should be providing you with an installation certificate, this will give the client an overall impression of the current state of the current electrical installation
