As for when it started, there was no actual declaration of war. The Confederacy could claim that it didn't want a war at all; it just wanted to defend its borders. Lincoln could not declare war on the Confederacy, because Congress did not recognise it as a sovereign nation.
The first shots were fired by the Confederates at the US Army garrison on the island of Fort Sumter in Charleston harbour on April 12th 1861, and Lincoln called for volunteer troops. The war was on.
The British were, by and large, a dominating force. The American Colonies occupied land that the British would’ve claimed as their own. Infuriated, the British would vehemently disagree with the claim of American Colonials being treated unfairly. Throughout history, the British have experienced many successes and failures. Many times, they discover land only to lose it to another country. For example, the laborious endeavors the British had gone through to conquer India had come to waste when India decided to declare independence. Similarly, the American colonials split from the British. So no, I do not think the British thought the mistreatment towards the colonials was in any way unfair.
