Radio-frequency, indirect dark matter searches have recently been gainingprevalence, due to the high sensitivity and resolution capabilities of the newgeneration of radio interferometers. MeerKAT is currently one of the mostsensitive instruments of its kind, making it ideal for indirect dark mattersearches. By making use of publicly available data from the MeerKAT GalaxyCluster Legacy Survey we are able to use both the observed diffuse synchrotronemission and non-detections to constrain the WIMP dark matter parameter space.In addition to a subset of generic WIMP annihilation channels, we probe thedark matter candidate within the 2HDM+S particle physics model, which wasdeveloped as an explanation for anomalies observed in the Large Hadron Colliderdata from runs 1 and 2. By undertaking a statistical analysis of the radio fluxdensities within galaxy clusters we are able to exclude the thermal relic valuefor WIMP masses $< \, \sim 1000 $ GeV for annihilation into bottom quarks withour median case. This is competitive with the best constraints in the currentliterature.
