The price comparison tool has been designed to search for loans that are only available through mortgage brokers in addition to loans offered by banks and other lenders.
Google claim it will be able to search through and compare aproximately 5000 different mortgage deals.
Users are able to refine and filter their searches to find a more personalised list of offers providing they give more information about their needs and personal circumstances. Users are also able to navigate through various 'best-buy' tables to help them chose their mortgage.
A spokesman for the company said:
"We will ask sufficient questions to allow the user to get meaningful search results"
Google has claimed that it would not record or keep any personal data about users if they followed a link through to a direct lender but would retain 'basic' information to allow brokers to call users back.
Google also requires the companies that participate to follow a code of conduct to ensure that customers are treated fairly. The total fees that the customer pays will be capped at 1pc of the loan.
Today's launch follows Google's move into comparison tools for car insurance, credit cards and bank accounts.
John Paleomylites, a product director at Google, said:
"Over the last few months we have launched new comparison services for credit cards, current and savings accounts and car insurance. We are now adding mortgages to our comparison family, making it easier for customers to find the best deal for their individual circumstances."
This year Google had suspended an earlier mortgage comparison service.
