Study of pressure effects on magnetic and transport properties of CeCo_{12}B_6 and CeFe_2Co_{10}B_6 was performed in temperature range 5-300 K at pressures up to 9 kbar. The significant decrease in the Curie temperature T_C as a consequence of Fe substitution from (135±1) K to (85±1) K is not accompanied by the changes of saturation magnetization. The decrease in T_C with pressure is the same for both samples -ΔT_C/Δp ≈ -0.5 K/kbar. The relative decrease in saturation magnetization with pressure is about 0.3%/kbar for both samples. Pressure induced resistivity changes were below 1%. The relatively low pressure effect on both the T_C and magnetization can be attributed to the hybridization as a consequence of small distances between the Co and B atoms.
