Abstract There are various surveys that will provide excellent data to search for and localize fast radio bursts (FRBs). The BINGO project will be one such survey, and this collaboration has already estimated an FRB detection rate that the project will yield. We present a forecast of the future constraints on our current cosmological model that the BINGO FRB detections and localizations will have when added to other current cosmological data sets. We quantify the dispersion measure (DM) as a function of redshift ( z ) for the BINGO FRB mock sample. Furthermore, we use current data sets (supernova, baryonic acoustic oscillation, and cosmic microwave background data) prior to assessing the efficacy of constraining dark energy models using Monte Carlo methods. Our results show that a spatially localized BINGO FRB data set will provide promising constraints on the population of host galaxies' intrinsic DM and be able to measure the nuisance parameters present within an FRB cosmological analysis. They will also provide alternative estimates on other parameters such as the Hubble constant and the dark energy equation of state. In particular, we should see that BINGO FRB data can put constraints on the degenerate w − H 0 plane, which the cosmic microwave background is incapable of measuring, allowing FRBs to be a viable alternative to baryonic acoustic oscillation to constrain the dark energy equation of state. We conclude that FRBs remain a promising future probe for cosmology and that the FRBs localized by the BINGO project will contribute significantly to our knowledge of the current cosmological model.
