FTTP, FTTC & ADSL - How do they work and what’s the difference?

Jun 23, 2025

FTTP, FTTC & ADSL: Which Connection Will Power Your Business Forward?

Your business connectivity isn't just about getting online—it's about choosing the foundation that will enable your team to collaborate seamlessly, serve customers exceptionally, and scale confidently. With 94% of UK small businesses experiencing poor internet connectivity that directly impacts their operations, understanding your broadband options has never been more critical.

Whether you're running a growing start-up, managing a medium-sized enterprise, or leading a large organization, the right connectivity choice can transform how your business operates. Let's explore how ADSL, FTTC, and FTTP each serve different business needs, and why making the right choice now could save you from costly disruptions later.

Why Your Connectivity Choice Matters More Than Ever

Your internet connection affects everything from daily productivity to customer satisfaction. Recent research shows that 26% of UK businesses have lost revenue due to connectivity issues, while 40% report that poor internet performance has negatively impacted their customer experience. These aren't just technical problems—they're business-critical challenges that demand the right solution.

At Amvia, we've helped businesses across the UK navigate these connectivity decisions with a human-first approach that larger providers simply can't match. Our team of connectivity experts provides direct access to advice and support, ensuring you get the right solution for your specific needs—not just what's easiest to install.

ADSL: When Basic Connectivity Meets Budget Constraints

Best for: Very small businesses with minimal online requirements and tight budgets

ADSL (Asymmetric Digital Subscriber Line) uses your existing phone line to deliver internet access alongside traditional voice services. While it's the most basic option available, it can still serve specific business scenarios effectively.

How ADSL Works for Your Business

ADSL divides your phone line's frequency spectrum to handle both voice calls and data transmission simultaneously. The technology is "asymmetric" because it provides faster download speeds compared to upload speeds—typically delivering 8-24 Mbps download with just 1-3 Mbps upload.

Your connection speed depends heavily on your distance from the local telephone exchange. Businesses within 1km typically achieve near-maximum performance, but those 3-4km away may see speeds drop to 8-10 Mbps or lower.

When ADSL Makes Sense

ADSL might work for your business if you:

  • Primarily use email and basic web browsing

  • Have fewer than 5 employees working online simultaneously

  • Operate in a location where other options aren't available

  • Need the most cost-effective solution available

ADSL Limitations That Could Impact Your Growth

However, ADSL's constraints become apparent quickly as businesses grow. With 30% of UK SMEs currently settling for download speeds under 10 Mbps, many find themselves constrained by ADSL's upload limitations. If your business relies on cloud applications, video conferencing, or needs to upload large files regularly, ADSL's 1-3 Mbps upload speeds will create frustrating bottlenecks.

FTTC: The Practical Step-Up for Growing Businesses

Best for: Small to medium businesses needing reliable performance without premium pricing

FTTC (Fibre to the Cabinet) represents the sweet spot for many UK businesses, combining improved performance with practical affordability. This hybrid solution delivers fibre optic cables to street-side cabinets, then uses existing copper lines for the final connection to your premises.

How FTTC Delivers Better Business Performance

FTTC typically provides 35-80 Mbps download speeds with 15-20 Mbps upload speeds—a substantial improvement over ADSL that can transform your daily operations. The fibre backbone eliminates many signal degradation issues, while shorter copper runs from cabinet to premises maintain consistent performance.

Business Benefits You'll Notice Immediately

With FTTC, your business gains:

  • Faster file sharing and cloud access enabling real-time collaboration

  • Improved video conferencing quality for better client interactions

  • Reduced waiting times for uploads and downloads

  • Support for more simultaneous users without performance degradation

Understanding FTTC's Distance Factor

Your distance from the street cabinet affects performance—businesses within 500 meters typically receive optimal speeds, while those 1-2 kilometres away may see reduced performance. However, this distance dependency is much less severe than with ADSL.

FTTP: Future-Proof Connectivity for Ambitious Businesses

Best for: Medium to large businesses planning for growth and digital transformation

FTTP (Fibre to the Premises) delivers fibre optic cables directly to your business premises, eliminating copper infrastructure entirely. This represents the gold standard for business connectivity, offering unmatched performance, reliability, and scalability.

How FTTP Transforms Business Operations

FTTP transmits data as light pulses through glass fibres, which are immune to electromagnetic interference and don't suffer signal degradation over distance. This enables symmetric speeds—equal upload and download capabilities—ranging from 60 Mbps to over 1,000 Mbps.

The Competitive Advantages FTTP Delivers

Businesses choosing FTTP benefit from:

  • Consistent performance regardless of location enabling reliable operations

  • Symmetric speeds perfect for cloud-first operations and video collaboration

  • Exceptional reliability with fibre cables designed for 40+ year lifespans

  • Enhanced security as fibre connections are extremely difficult to intercept

  • Future-proof scalability supporting growth without infrastructure changes

Real-World Performance Differences

Testing shows FTTP users experience 94% less latency during peak hours compared to FTTC subscribers—crucial for real-time applications like video calls and cloud-based software that requires immediate responsiveness.

Matching Connectivity to Your Business Size and Needs

Small Businesses (1-10 employees)

If you're running a small business, your connectivity needs depend heavily on how you operate. Traditional retail or service businesses with basic online needs might find ADSL sufficient initially, but most modern small businesses benefit from FTTC's improved performance.

Consider FTTC if you:

  • Use cloud-based applications for accounting, CRM, or project management

  • Conduct regular video calls with clients or remote team members

  • Need to upload marketing materials, proposals, or client deliverables

  • Want room for growth without connectivity constraints

Medium Businesses (10-50 employees)

Medium-sized businesses typically require FTTC as a minimum, with many benefiting from FTTP's additional capabilities. With multiple employees accessing cloud applications simultaneously, the symmetric speeds and reliability of FTTP become increasingly valuable.

FTTP makes sense when you:

  • Operate across multiple locations requiring consistent connectivity

  • Rely heavily on cloud-based business applications

  • Conduct frequent video conferences with multiple participants

  • Handle large file transfers or data backups regularly

Large Businesses (50+ employees)

Large businesses should seriously consider FTTP as their primary connectivity solution. The combination of high-speed symmetric connectivity, reliability, and scalability aligns with the complex needs of larger operations.

FTTP becomes essential for:

  • Supporting heavy simultaneous usage across departments

  • Enabling seamless collaboration between remote and office-based teams

  • Maintaining consistent performance during peak usage periods

  • Supporting advanced applications like VoIP phone systems and video conferencing
