Is there a way I can increase my payments or at least make sure they don’t go down over the summer

yes, go to help in the app,ask wattbot, type "message the team" and explain. They will calculate a new DD for you to bring you back on track. Replies are not instant- a day or 2.
Your annual estimate must have been a fair way out because £375 is a lot and, when your dd is taken you should be about 1 monthly payment in credit. Do PP have the correct meter readings? Have you checked your statement?
If it's all correct then be prepared for a sizeable increase to bring you back into line, but I'd be more concerned as to why it's so far out in the first place. May I ask how much was your colder months payment?
