  We report the confirmation and characterisation of TOI-1820~b, TOI-2025~b,
and TOI-2158~b, three Jupiter-sized planets on short-period orbits around
G-type stars detected by TESS. Through our ground-based efforts using the FIES
and Tull spectrographs, we have confirmed these planets and characterised their
orbits, and find periods of around $4.9$~d, $8.9$~d, and $8.6$~d for
TOI-1820~b, TOI-2025~b, and TOI-2158~b, respectively. The sizes of the planets
range from 0.96 to 1.14 Jupiter radii, and their masses are in the range from
0.8 to 4.4 Jupiter masses. For two of the systems, namely TOI-2025 and
TOI-2158, we see a long-term trend in the radial velocities, indicating the
presence of an outer companion in each of the two systems. For TOI-2025 we
furthermore find the star to be well-aligned with the orbit, with a projected
obliquity of $9^{+33}_{-31}$~$^\circ$. As these planets are all found in
relatively bright systems (V$\sim$10.9-11.6 mag), they are well-suited for
further studies, which could help shed light on the formation and migration of
hot and warm Jupiters.
