I've just finished two books from the "Chronicles of St. Mary's" series by Jodi Taylor. She's a West Country lass, Kaz, with roots in Gloucester!
They're about a group of mad-cap scientists who hurtle around Time, visiting various historical events like the Siege of Troy and the Great Fire of London for "research purposes". Very funny, very entertaining, and an excellent cast of eccentric heroes from the main character, Dr Madeleine Maxwell, Chief Operations Officer, to Mavis Enderby, Head of Wardrobe. I think she writes more contemporary light romance novels as well, using the name Isabella Barclay, who confusingly is one of the "villains" in the St. Mary's series.
