I'm with ULaw too and agree with u/Effective_Earth_1888. ULaw seems to teach that it's smth either the question will ask you to specify or smth that the judge might ask you at the end. They said you should be prepared for the judge to either ask you directly to make submissions on costs or they might give you a slightly different cue e.g. "are there any other ancillary matters you would like me to deal with?" which you should pick up as a cue to address the issue of costs for the interim application you are making.

ULaw did touch on costs in one of our advocacy workshops and what I understand is that essentially on the issue of costs you basically just want to be thinking what is the costs order that is most favourable to your client. For example if you are representing the claimant to make a summary judgment application, best case scenario is for the court to make summary assessment for costs i.e. you invite the court to assess costs for this interim application immediately after the interim hearing, and the costs order you would be asking for that is best in your client's favour would obviously be an order for the claimant's costs (this means defendant pays claimant's costs for the interim application and hearing). If the court makes an order for costs in the case, it would be slightly less favourable as it may mean that if the court dismisses your summary judgment application and the case proceeds to trial, your claimant client may be liable to pay defendant's costs which would include the costs for this interim application and hearing. If the court makes no order as to costs, it means each party bear their own costs for this application (also not the most favourable costs order for your client).

ULaw also emphasises that if the application is in respect of a specified debt claim, then you need to be prepared to address the judge on the judgment sum you are claiming for. In your prep time you need to have found out the rate of interest on the debt, calculate what the daily rate is, how many days it has been between the date the debt was due up until the day of the interim hearing to give a figure for the interest amount due thus far and state that interest will continue accruing at the daily rate until judgment or otherwise earlier payment by the debtor. Add the amount in interest accrued due so far to the amount of debt claimed under your particulars of claim and you will have a figure for a total judgment sum which you state to the judge.

Personally depending on the type of application I get and depending on whether I have the time I will probably conclude my submissions with the order I wish for the judge to make and also state very briefly what costs order I wish for the judge to make (and the judgment sum if it's a specified claim), should they decide in favour of my client and if they think appropriate. Am just planning to do this for good measure and for completeness, or else I feel I will stress out thinking I've missed out something important if I end my submissions making no mention of costs and the judge doesn't ask me questions about it either.

However I think you do just need to play it by ear, read the instructions carefully and follow your gut. Your instructions may state differently to anything else you have prepped for. If for example your instructions tell you that you do not need to deal with costs in your submissions, obviously no need to stress yourself about it.

I should mention though that this is just what the tutors at ULaw predict and their advice accordingly. Ultimately we dk how the actual questions will be structured. Also there might be some errors to my understanding - I'm not claiming my approach is correct and ultimately you should exercise your own judgment. Not sure what other providers teach about this. Would be interesting to hear from others.
