Welcome to you Twick Air
Don't let the lousy weather put you off. When I started my PPL my record was 14 lessons cancelled in a row !!!!
And to echo the above postings, do make good use of your cancelled lessons. It is always worthwhile (if your school offers relevant courses) to sit in on, for example, a trainee flying instructors briefings. Or persuade your instructor to give you some one to one instruction. Even if they chrge you £25 hour, you will learn a lot and will be making good use of your time and theirs.
Good luck and enjoy yourself.
