Hi Tobias welcome to the forum.
Not British, the lion passant is walking the right way which makes it Dutch.
6 Eggnog / mocha or teaspoons; made by the silversmith firm of J. Schijfsma & Son. Johannes Schijfsma Jr, together with his father Johannes Jans Schijfsma, started their firm in the city of Woudsend and later settled in the city of Sneek , registered from 1844 up till 1902 when another son of the Schijsfma family took over the shop. In 1942 the firm of J. Schijfsma was sold to a companion and changed name.
Five of your spoons carry the Gothic date letter G for 1866, and one spoon has the date letter A for 1910 with the maker’s mark; JS above a dot for; Johannes Henricus Schijfsma, the son of Schijfsma Jr .
For more information about the lion passant above 2, the standard mark or about the Minerva head, office mark and date letters see:
