Consumers should be able to see what broadband speeds are accessible at a specific address, rather than just a postcode.
This is the view of the Local Government Association (LGA), which said there is currently no single place where consumers can compare side-by-side estimates of the broadband speeds that providers could supply to their property.
The LGA acknowledged that people can conduct a line speed test on every potential broadband provider's website to get a realistic view of the speeds they could receive at their premises.
However, it said this is complicated and time-consuming for those who want a straightforward view of the market.
The LGA stated that this in turn makes it more difficult for consumers to pick the best broadband deal.
As a result, it is calling on providers to open up their data so the estimated speeds people can receive at home can be compared more easily.
The organisation also wants sector watchdog Ofcom to have the power to request address level data from broadband companies so it can monitor the accuracy of speed predictions.
Cllr Mark Hawthorne, Chairman of the People and Places Board at the LGA, commented: "The quality of digital connectivity can be markedly different from area to area, with some households being able to access superfast broadband speeds, whilst others can only achieve substantially less.
"We support the government's aims to allow Ofcom to demand providers open up their premises-level data on broadband so that residents can more easily compare who will provide the best service to their home - not just their postcode, which can often be inaccurate.
"Our residents can only make the most informed choices if they have all the data at their fingertips in one place."
Cllr Hawthorne added that local authorities are working hard to ensure that everybody can access a good-quality internet connection.
This comes after the LGA criticised broadband providers for making "misleading" speed claims in their advertisements.
Providers are currently allowed to advertise broadband speeds if they are available to just ten per cent of their customers.
The LGA said this means they are pushing headline figures that do not reflect the experiences of most users, in particular people in rural areas. As a result, the body wants the rules to be changed so that broadband providers can only promote average speeds.
