Bluebells suffer first home defeat of the season.
Taunton opened the scoring inside six minutes as Ben Seymour fired past Aaron Sainsbury to give the Peacocks an early lead.
The visitors continued to come forward and extended their lead just before the half hour mark. Taunton delivered a cross from deep with Scott Robinson rising highest to head home, to add a second for the Peacocks.
Three minutes later Taunton would add a third. Following a quick break the ball would end up on the left of the penalty area with Jack Rice who curled his effort past Sainsbury.
There would however be a lifeline for Yate, as five minutes from the interval Rex Mannings would get on the score sheet. Following a long throw it fell to Mannings inside the area who fired through the legs of Freddie Godden.

The hosts came out firing in the second half and created many chances to try and cut the deficit further, but were just unable to find the final pass.
In the 90th minute the visitors put the game to bed. Substitute Dan Koita got onto the end of a ball over the top of the Yate backline before lobbing Sainsbury to get Taunton their fourth.
