Spectrum Internet is reportedly the first provider to offer broadband services using the Openreach 500Mbps and 1000Mbps FTTP tiers.
This follows a relatively long wait for these technologies to have an impact on retail broadband delivery.
Think Broadband reported that the ISP - which to date has focused on serving parts of south-west England and south Wales - is now offering two packages with price tags that match the speeds on offer.
One product offers download speeds of 1000Mbps and upload speeds of 220Mbps for a monthly cost of £99 for six months, increasing to £159 after that.
The other option promises 500Mbps downloads and 165Mbps uploads for £69 per month, rising to £99 per month after six months.
Both packages come on a 12-month contract and charge a £599 activation fee, which includes a Zyxel router.
The high price tags mean these products could be more suited to businesses.
Residential customers have the option of a 76Mpbs download/19Mbps upload service, costing £29 per month for six months and £35.99 per month thereafter.
This package still comes with a relatively high setup fee of £119, due to Openreach charges and the extra work required to deliver faster FTTP connectivity.
