Defence secretary Philip Hammond has said that the UK will be "putting a small team" in the British Baghdad embassy, to increase awareness and help plan for possible emergency situations.
Mr Hammond also said that the British government will only give "technical advice" to Iraq at this stage, which will be delivered through either military or civilian methods.
The statement comes after increased sectarian violence in the north of Iraq by Islamic militants.
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
