All products are uncontended and provide symmetric upload and download speeds. Unlike shared broadband where speeds drop during peak times, your dedicated London leased line maintains consistent performance 24/7. Business-critical traffic never mixes with residential users, ensuring predictable, reliable connectivity for VoIP, video conferencing, cloud applications, and large file transfers regardless of time of day.
BGP (Border Gateway Protocol) routing is available for IP failover, providing enterprise-grade network resilience. Automatically route traffic through alternative paths if primary connection fails, ensuring zero downtime for mission-critical operations. Advanced routing capabilities support complex multi-site networks, enabling seamless failover and load balancing across multiple connections for maximum reliability and performance.
On 10G, 25G and 100G Diverse products we offer managed failover with Protected Internet (IPP). Our team monitors both connections continuously, automatically switching to backup when issues are detected. Unlike manual failover that requires intervention, managed failover happens in seconds without human input, protecting your business from extended outages and ensuring continuous operations even during major infrastructure failures.
This enables you to upsell bandwidth to your customers during the term for upgraded services. As your business grows, easily scale from 1Gbps to 10Gbps, 25Gbps, or even 100Gbps without changing infrastructure or experiencing downtime. Bandwidth upgrades can be completed within days, not months, allowing you to respond quickly to changing business requirements or seasonal demand spikes.
A /29 or /30 IPv4 address allocation comes at no additional charge. If you require more IP addresses, they are priced separately and start from /27 blocks. Static IP addresses enable you to host servers, run VPNs, configure remote access, and implement advanced security policies. Essential for businesses running their own services or requiring consistent external IP addresses for whitelisting and security configurations.
Installation Process
The process begins with a consultation to assess your business requirements, including speed, bandwidth, and scalability needs.
A thorough site survey will be conducted to evaluate your premises and determine the optimal route for the fibre connection. A tailored commercial proposal is presented, detailing pricing, terms, and installation timelines with no hidden fees. Once the proposal is approved, the installation is scheduled at a time that works for you.
Engineers deploy a dedicated fibre connection to your premises, ensuring minimal disruption to your operations. The fibre is integrated with your existing infrastructure, providing seamless connectivity without downtime. The connection is rigorously tested to ensure it meets the guaranteed speeds and bandwidth outlined in your SLA.
What Speeds are available?
London Leased Lines offers enterprise-grade speeds designed to meet the demands of modern businesses.
With a minimum starting speed of 1Gbps, we provide a level of connectivity far beyond traditional providers, ensuring your business stays ahead in an increasingly digital landscape. For organisations with higher requirements, the service is fully scalable up to an impressive 100Gbps, offering unmatched capacity for data-intensive operations like cloud computing, video conferencing, and large-scale data transfers.
These dedicated speeds are guaranteed, as we use our own network infrastructure exclusively for business traffic, ensuring consistent, reliable performance regardless of demand.
FAQs
Leased lines offer numerous benefits for businesses, with the primary advantage being high symmetric speeds that ensure seamless connectivity and fast uploads and downloads. They are also highly reliable and adaptable to your needs. Additionally, setting up a leased line provides access to exceptional customer support from our team of experts.
A leased line provides a dedicated, uncontended connection between your premises and the local exchange, ensuring it is exclusively used by your business. In contrast, broadband is a shared connection, utilised by multiple users.
After your leased line is installed, you may decide to increase your speed if needed. If there is available capacity on the bearer line, you can easily upgrade your speed. Simply reach out to our team, and they will arrange the bandwidth increase for you.
Award winning call solutions
Tailor-picked solutions designed for small to medium-sized businesses
Web-based Call Management
Calls to your business number can be diverted to your target (landline or mobile) during your operational business hours. Once you have configured your 'in-hours', choose where you would like to divert calls 'outside of working hours'. If calls are not configured to be diverted outside working hours, then voicemail-to-email is activated, meaning that calls are always captured.
Open the Call Manager to access the time schedule and set business open hours. Calls received in-hours can be configured to route to any UK landline number (01/02) or UK mobile (07). Your call-forwarding changes are saved and active at the click of a button.
Calls received outside business hours can also be routed to phone or voicemail. Ensure that you can identify business calls when answering from a mobile or home phone outside of business hours.
Web-based Call Managment is Included with Silver, Gold and Platinum Tariffs

Virtual Receptionist
More calls are being answered on mobile phones than ever before, a trend that's only growing with the rise of remote and home working. The mobile phone, with its portability and flexibility, is the perfect tool for handling calls on the move. When paired with the Virtual Receptionist, it provides users with a sense of security and peace of mind, knowing that every call is professionally introduced. The whisper message feature further enhances this, helping users distinguish between personal and business calls.
With the Virtual Receptionist, the caller will never hear your personal mobile voicemail message. It is less professional to hear "You are through to the Giff Gaff mobile voicemail" than "Thank you for calling Prime Roofing; please leave a message after the tone, and a team member will call you back within 24 hours." This helps with your brand image, giving the impression of a large, reputable, well-established business, boosting your confidence and credibility.
The Virtual Receptionist from only £19.99 per month
Real-time Call Data and Analytics
Call Analytics is an online platform that gives you complete insight into your business calls from a single interface. Review the success of your marketing campaigns and staff call handling at a glance. If your business uses multiple numbers across various marketing campaigns, you can monitor which campaigns are receiving the greatest response.
With detailed Call Analytics, you can accurately measure the results of when customers called, their geographical location, how long the call lasted and if they called more than once. Analysing the details of your telecommunication activities allows you to gain valuable market insight, re-focus your marketing efforts, boost sales and increase customer satisfaction.
