'Deep distrust'
He said Britain and Iran had a "difficult history", but relations had been steadily getting better and reopening diplomacy was a "sensible way forward".
"Yes, we should tread carefully. There is a deep legacy of distrust on both sides, and we have major areas where we have very substantial policy differences, but that doesn't mean we shouldn't be talking.
"We do see eye to eye on the need to interdict the opium traffic between Afghanistan and Europe, we do see eye to eye on the need to challenge Isil [also known as Islamic State]," he said.
He was "not blind" to areas of contention, including Iran's human rights record, but the UK would not be able to influence such issues unless it opened a dialogue with the country's leaders, he said.
Mr Hammond's visit and the reopening of the embassy comes weeks after Iran reached a deal with six world powers aimed at curbing its nuclear programme.
Initially, the embassy will be headed by a charge d'affaires, Ajay Sharma, but Mr Hammond said an agreement on upgrading to full ambassador status is expected to be reached in the coming months.
'Best bet'
The foreign secretary acknowledged there were no guarantees the Iranian regime would not pursue a nuclear weapons programme in the future, but "you have to make a judgement".
"My judgement is that whatever Iran has or hasn't been doing in the past, the regime, the Iranian people, have come to the conclusion that pursuing, or being believed to pursue, an illegal military nuclear programme just imposes too great a cost on Iran," he said.
An Iran that was no longer isolated was "the best bet for the future", he said.
In November 2011 Iran announced it was expelling the UK's ambassador in retaliation for British support for tougher sanctions on Tehran over its nuclear programme.
Hundreds of protesters stormed embassy compounds two days later, smashing windows, torching cars and burning union jacks.
The UK responded by closing the Iranian embassy in London later that month.
But following the election of Mr Rouhani and an agreement on how to deal with Iran's nuclear programme, the then Foreign Secretary William Hague proposed the reopening of the embassy in June last year.
Since then, the reopening has been held up by technical problems over visa policy and communications equipment, Mr Hammond has said.
