Budget's affinity arm, Junction, has won the contract to run a motor insurance scheme for the Police Mutual Assurance Society (PMAS).
With 170,000 members PMAS is the largest affinity-based friendly society in the UK representing serving officers, retired officers, support staff and their families.
Junction head of business development Matt Munro said: "PMAS has a fantastic reputation for providing tailored financial products and security to its members, and we are delighted to be their chosen affinity partner for motor insurance."
The scheme is based on a five-year contract and will launch in April. All sales and customer services will be managed from Junction's contact centre in Sunderland.
PMAS marketing director Clare Preston said: "We have to be certain that whoever we choose offers not only excellent value-for-money, but meets our high service standards too. We are confident that Junction lives up to our high standards."
