  Large Hadron Collider (LHC) searches for the SM Higgs boson provide a
powerful limit on models involving Universal Extra Dimensions (UED) where the
Higgs production is enhanced. We have evaluated all one-loop diagrams for Higgs
production from gluon fusion and decay to two photons within "minimal" UED
(mUED), independently confirming previous results, and we have evaluated
enhancement factors for Higgs boson production and decay over the mUED
parameter space. Using these we have derived limits on the parameter space,
combining data from both ATLAS and CMS collaborations for the most recent 7 TeV
and 8 TeV LHC data. We have performed a rigorous statistical combination of
several Higgs boson search channels which is important because mUED signatures
from the Higgs boson are not universally enhanced.
  We have found that 1/R < 500 GeV is excluded at 95% CL, while for larger 1/R
only a very narrow (\pm1-4 GeV) mass window around m_h = 125 GeV and another
window (up to 2 GeV wide for 1/R > 1000 GeV) around m_h = 118 GeV are left. The
latter is likely to be excluded as more data becomes available whereas the
region around 125 GeV is where the recently discovered Higgs-like particle was
observed and therefore where the exclusion limit is weaker.
  It is worth stressing that mUED predicts an enhancement for all channels for
Higgs production by gluon fusion and decay while the vector boson fusion
process WW/ZZ -> h -> AA is generically suppressed and WW/ZZ -> h -> WW*/ZZ* is
standard. Therefore, as more 8 TeV LHC data becomes available, the information
on individual Higgs boson production and decay processes provided by the CMS
and ATLAS experiments can be effectively used to favour mUED or exclude it
further.
