It was last serviced in the summer. I've had it serviced every 12 months except for the last service where there was a 16 month interval between services. I guessing that my warranty my now be invalid?

Worcester are very accommodating to their consumers.

If the service record is generally correct I expect they would accept a slight delay on just one service date.
