RCD installation, potential new switchboard

My home doesn't have RCD, I would like to install RCD for all of the switches. Totally, in the switchboard, there are 4 lighting, 2 powers, 1 hot water, 1 oven and 1 cooking hob. Potentially we have to redo the whole switchboard since currently there are not enough slot to put in extra RCD. I also have a few small jobs around the house i.e. outside light bulb is not working, change light bulb socket, change broken power point etc...
