  The production of $\Upsilon$ mesons in $pp$ collisions at $\sqrt=7$ and
$8\,\mathrm{TeV}$ is studied with the LHCb detector using data samples
corresponding to an integrated luminosity of $1\,\mathrm{fb}^{-1}$ and
$2\,\mathrm{fb}^{-1}$ respectively. The production cross-sections and ratios of
cross-sections are measured as functions of the meson transverse momentum $p_T$
and rapidity $y$, for $p_T<30\,\mathrm{GeV}/c$} and $2.0<y<4.5$.
