We use exceptional field theory to systematically study all possible consistent truncations around half-maximal AdS5 vacua of M-theory. We show that only truncations with at most three vector multiplets are consistent. The possible gaugings are SU(2)×U(1) and ISO(3)×U(1) where, in the first case, the U(1) factor can have different embeddings inside the global symmetry group SO(5,n), where n ≤ 3 equals the number of vector multiplets. We show that the ISO(3)×U(1) truncation only exists around vacua that are locally an S4 fibration over a Riemann surface, and argue that this is the only consistent truncation with vector multiplets around these vacua that can be constructed by going through the 7-dimensional SO(5) gauged supergravity obtained after an S4 reduction. The consistent truncations with SU(2)×U(1) gaugings with vector multiplets exist only if certain conditions are satisfied, which we derive.
