Gaps between wall and floor

[[ASSE]Hinchy]

First post here guys. Currently doing up my granddad's old house and as I don't have an ounce of DIY competence in me, it is proving very expensive

We are having a new kitchen fitted next week. However, before the units are fitted I want to ensure that the room is as draft proof as possible.

At the moment, as can be seen in the below pictures, there is a fair gap between the floorboards and walls. Whilst some of these areas will be covered by the base units, others will only be covered once the Karndean floor has been laid and skirting boards fitted. However, I want to get the gaps filled even behind the base units as the room has apparently always been pretty cold.

What is the best way to go about this? I had thought expanding foam but given what I have said already about my knowledge, I felt I should check!

Would be grateful for the assistance, thanks.

Something like this?

I think the decorator used this between the skirts and the floor in one of the bedrooms. Some of the gaps, as you can see, look to be quite big though. Certainly bigger than the ones that were in the bedroom.

Do you think the silicone which looks to apply at 6mm could be doubled up in those areas?

Thanks for the advice so far guys.

The main bits I'm concerned with are those that will be behind the units and therefore won't have a skirt around. This means that there will be that gap between wall and floor, albeit behind the base units but still letting in colder air than is necessary to.

The parts which will have a skirting board as you say can just be sealed easily when it comes to fitting them.
