UK Trade and Investment for Defence and Security Organisation (UKTI DSO) senior spokesperson Adam Thomas said: "We want to see more Malaysian companies looking to the UK for future market[s].
"We have seen tremendous development in the industrial sector in defence and security and we see no reason why Malaysian companies should not be in the UK.
"If you do supply to our armed forces there would be a very, very good opportunity to supply to other armed forces around the world."
Thomas said that the Malaysian companies can register their capabilities on a newly developed website, www.contracts.mod.uk, and also provide information regarding their profile.
"We can look at your company and see if they are suitable to supply for our armed forces or we can give them advice on areas that they need to develop in order to do so," Thomas added.
"We also have one of the most open procurement systems in the world and there are no barriers to the Malaysian market at all."
The MoD has allocated more than 40% of the UK defence budget to foreign companies, with approximately MYR100.6bn (£18.5bn) spent with third parties in the financial year 2012 to 2013.
The UKTI DSO is also keen to participate in the modernisation of the Malaysian armed forces, the cyber and security sector, and education, according to Thomas.
The UK MoD launched a ten-year £160bn equipment plan in January 2013.
