Dear Neighbour, 
Solihull Council have recommended that residents who are planning a firework display give notice to neighbours. This is in order to allow them to make preparations that will minimise the effects of firework use on vulnerable people and animals. 
We are sending you a copy of this letter to you as we are planning to use fireworks on [DELETE AND INSERT DATE].   
The display is expected to start at approximately [DELETE AND INSERT TIME] and end at [DELETE AND INSERT TIME].
Please accept our apologies for the noise and disruption this may cause. We hope that by providing this notice, we have given you sufficient time to make plans to lessen the effects of noise and disruption on any person or pet in your household.  

Kind regards, 
[INSERT ADDRESS] 
OR
A fellow neighbour in your area.
