We present the discovery of only the third brown dwarf known to eclipse anon-accreting white dwarf. Gaia parallax information and multi-colourphotometry confirm that the white dwarf is cool (9950$\pm$150K) and has a lowmass (0.45$\pm$0.05~MSun), and spectra and lightcurves suggest the brown dwarfhas a mass of 0.067 $\pm$0.006 MSun (70 MJup) and a spectral type of L5 $\pm$1.The kinematics of the system show that the binary is likely to be a member ofthe thick disk and therefore at least 5 Gyr old. The high cadence lightcurvesshow that the brown dwarf is inflated, making it the first brown dwarf in aneclipsing white dwarf-brown dwarf binary to be so.
