The Tory MP for North West Norfolk romped home to a comfortable win in Thursday's General Election, increasing his lead over Labour to 9,180 votes from 3,485 in 2001.
Immediately after his victory, he vowed to tackle the lack of affordable housing in the area, fight for rural issues and lead the regeneration of Lynn.
Speaking to the Lynn News, Mr Bellingham said: "The key agenda is to make sure we take a proactive part in making sure that the big schemes, such as the Nar Ouse Regeneration, are delivered effectively.
"I was very, very pleased to see my vote go up, but no MP in the country can take anything for granted. They have to earn their respect and votes."
Mr Bellingham paid a special tribute to his wife Emma, who he said had played a crucial role in his re-election.
But the Tory MP admitted he had dropped a bit of a clanger during his acceptance speech at Lynn's Corn Exchange.
"Emma was over the moon with the result, but she did tick me off, and quite rightly so, for not thanking her in my address.
"She has kept me sane throughout the campaign. I have maybe been impossible to live with, because I've been working flat out and it has not been easy for our young boy."
Mr Bellingham said he was disappointed by suggestions that he was only interested in serving the needs of a "privileged few".
He described the accusations as "appalling" and promised voters he was there to help everyone.
"Outrageous allegations have been made that I only look after people from certain backgrounds. They have been shown to be completely without any foundation whatsoever."
The 50-year-old said he would represent all individuals, regardless of their social or political background.
Labour candidate Damien Welfare blamed his defeat on an aggressive Tory campaign.
"We have obviously been affected by the war but I have to say I think some of the Conservative campaign nationally has been unfortunate."
Labour leaked votes to the Lib Dems and UKIP while the Tories enjoyed a modest gain of 1.8 per cent.
Despite his frustration, Mr Welfare insisted his campaign had gone largely to plan and pledged to continue his involvement in local issues.
"There are always things you could have done better and there are always snags that mean things don't go according to plan, but I think we have brought some important issues to the electorate," he said.
Lib Dem candidate Simon Higginson enjoyed the biggest gain in North West Norfolk with a 5.5 per cent increase in votes.
Supporters claimed the party had benefited from strong campaigning on issues such as the Iraq War and Council Tax reform.
Mr Higginson said: "The Lib Dems are very pleased with the results we have achieved locally. Three-party politics is here to stay."
The UK Independence Party won 1,861 votes, an increase of 2.3 per cent on the 2001 election.
Their candidate Mr Michael Stone, said he had enjoyed the election fight and promised to return in five years time.
"We put 21/2 times the vote on that we had last time, which I'm very pleased with. I will be back."
Henry Bellingham won just over 50 per cent of the North West Norfolk vote with 25,471 votes.
Around 61 per cent of those who were eligible to vote went to the polls.
