  Forecast constraints for a Symmetric Teleparallel Gravity model with a
$\Lambda$CDM background are made using forthcoming ground and space based
gravitational waves observatories. A Bayesian analysis resorting to generated
mock catalogs shows that LIGO is not expected to be able to distinguish this
model from $\Lambda$CDM, while both LISA and the ET will, with the ET
outperforming LISA. We also show that low redshift events are favored in order
to improve the quality of the constrains.
