The Queen has recognised Merton volunteer groups in her Award for Voluntary Service list.
Merton Street Pastors and the Jeremiah Project will both be awarded the UK national honour at a special ceremony in London.
A certificate signed by The Queen and an exclusive commemorative crystal will be presented by Her Majesty's Lord-Lieutenants at the ceremony.
More than 300 groups were nominated for the award this year, with 111 organisations chosen for inspiring the country to get involved in volunteering and make a difference in their community.
Merton Street Pastors is a team of volunteers from local churches who patrol the streets late at night and on weekends to help those in trouble.
The Jeremiah Project works with Mitcham churches to provide education, practical and pastoral support and help people reach their full potential.
The winners will have the opportunity to attend one of Her Majesty’s garden parties, held at Buckingham Palace during the summer months.
Martyn Lewis CBE, The Queen's Award for Voluntary Service Award Committee chairman, said: "With more than 15 million Britons now volunteering at least once a month, this year’s winners of the Queen’s Award for Voluntary Service have faced some tough competition."
