Relish and Hyperoptic have been honoured at the Internet Service Providers' Association's (ISPA) 18th Annual UK Internet Industry Awards.
Relish won the Best Consumer Broadband award largely on the strength of its "great and transparent service".
The ISPA also noted that judges were particularly impressed with its "focus on a customer base often ignored by other providers".
Hyperoptic, meanwhile, won the Best Superfast Broadband award, as its "incredible expansion has seem them double their footprint, but without compromising on top quality customer service or the speeds that have made them famous".
Nick Lansman, Secretary General of the ISPA, commented: "A huge range of companies won this year, showing the continued diversity, innovation and competitiveness of the UK internet industry in what has been an eventful year for the sector."
The accolade for Hyperoptic comes shortly after it confirmed it will roll out its 1Gbps fibre optic broadband service in seven more locations throughout the UK.
The ultra-fast broadband provider will make gigabit services available in Edinburgh, Portsmouth, Leicester, Southampton, Slough, Watford and Woking by 2018.
This will take the number of towns and cities serviced by Hyperoptic's network up to 20 and places further pressure on BT Openreach.
Steve Holford, Chief Customer Officer at Hyperoptic, commented: "The recognition that Hyperoptic continues to offer the Best Superfast Broadband in the UK is a fantastic coup for us.
"We operate in a difficult market - with older providers that are committed to try and keep consumers in the Dark Age to sweat their assets."
However, Mr Holford insisted that Hyperoptic's vision is "much more ambitious" and said British consumers and businesses "should not have to compromise on their connectivity".
"The trinity of speeds, consistency and flexibility should come as standard," he stated. "Having this continued support from our industry body is hugely motivating as we gear for continued growth."
