We can increase limits underneath your policy, however it would have to be for the remainder of your policy year. You can then reduce your cover back down at renewal.
Unfortunately we would not be able to cover you to lead workshops, as you would require Professional Indemnity cover, which is not offered under this policy.
We can cover you happily to be sewing at any time throughout the policy year. This cover is available to those who pursue this as a hobby, all the way to those who run a full-fledged business.
