Of course, flights are delayed for all kinds of reasons, not just poor weather.
If your flight is covered by UK law, your airline must let you choose between either getting a refund or being booked on to an alternative flight.
That’s regardless of how far in advance the cancellation was made.
You can get your money back for any part of the ticket you have not used.
So, if you booked a return flight and the outbound leg is cancelled, you can get the full cost of the return ticket refunded.
If you still want to travel, your airline must find you an alternative flight.
If another airline is flying to your destination significantly sooner, or there are other suitable modes of transport, then you have a right to be booked onto that alternative transport instead.
