  Photometric observations of occultations of transiting exoplanets can place
important constraints on the thermal emission and albedos of their atmospheres.
We analyse photometric measurements and derive geometric albedo
($A_\mathrm{g}$) constraints for five hot Jupiters observed with TESS in the
optical: WASP-18 b, WASP-36 b, WASP-43 b, WASP-50 b and WASP-51 b. For WASP-43
b, our results are complemented by a VLT/HAWK-I observation in the
near-infrared at $2.09~\mu$m. We derive the first geometric albedo constraints
for WASP-50 b and WASP-51 b: $A_\mathrm{g}<0.445$ and $A_\mathrm{g}<0.368$,
respectively. We find that WASP-43 b and WASP-18 b are both consistent with low
geometric albedos ($A_\mathrm{g}<0.16$) even though they lie at opposite ends
of the hot Jupiter temperature range with equilibrium temperatures of
$\sim1400$ K and $\sim2500$ K, respectively. We report self-consistent
atmospheric models which explain broadband observations for both planets from
TESS, \HST, \Spitzer and VLT/HAWK-I. We find that the data of both hot Jupiters
can be explained by thermal emission alone and inefficient day-night energy
redistribution. The data do not require optical scattering from clouds/hazes,
consistent with the low geometric albedos observed.
