Chambers attended just two meets in 2015. He had a more active 2016, winning his heat and semi-final in the 60m at the British Indoor Championships but only managed seventh in the final. At the outdoor national championships in June, he made the final of the 100m in which he ran a heavily wind assisted (+3.0 m/s) 10.11, which once again saw him finish seventh. In 2017, Chambers came third at the national indoor championships in 6.62 but was not selected for the 2017 European Indoor Championships. He could only reach the national semi-finals outdoors in July in the 100m, and announced his retirement the following month.
