Business Connectivity for Manchester Businesses: Broadband, Leased Lines and Getting It Right

Your internet connection is the one piece of infrastructure that, when it fails, takes almost everything else with it. Email stops. Cloud apps go down. VoIP calls drop. Remote workers are locked out. And if your entire office is sitting idle waiting for the connection to come back, the cost mounts up fast.

Yet business connectivity is one of the most underinvested areas of IT in smaller Manchester companies. Many businesses are still running on consumer-grade broadband, sharing a single line with no failover, and trusting that it’ll hold up. Sometimes it does. Sometimes it doesn’t — and that’s when you find out what it’s actually costing you.

This guide is designed to help Manchester businesses understand their connectivity options, what the differences between them actually mean in practice, and how to choose the right solution for where your business is now and where it’s heading.

Why Business Connectivity Is Different From Home Broadband

Consumer broadband is designed for downloading — streaming, browsing, gaming. It’s asymmetric by design: fast download speeds, slower upload speeds, and a “best efforts” service agreement that essentially means the provider doesn’t guarantee anything.

Business connectivity is built differently. The key differences are:

• Symmetrical speeds — equal upload and download, which matters enormously if your team is using cloud apps, video calls, or uploading files to clients
• Service Level Agreements (SLAs) — guaranteed uptime, response times if something goes wrong, and actual accountability
• Dedicated support lines — not the consumer helpdesk queue
• Static IP addresses — essential for VPNs, hosted services, and remote access
• Business-grade hardware — routers built to handle multiple users and workloads, not the plastic box the consumer ISP sends you

If you’re running a modern business that relies on Microsoft 365, cloud-hosted software, VoIP calls, or remote working — and almost every Manchester business does now — then your connectivity isn’t just a utility. It’s load-bearing infrastructure.

Your Business Connectivity Options Explained

FTTC (Fibre to the Cabinet) Broadband

This is the most common type of business broadband in the UK. The fibre runs from the exchange to a green street cabinet, then copper wire runs the last stretch to your premises. Speeds typically range from 30–80 Mbps download, with upload speeds significantly slower.

Good for: Small businesses with light cloud usage, email and basic web browsing. Lowest cost option.

Limitations: Upload speeds can become a bottleneck as your team grows. Speeds are contended — shared with other businesses and homes on the same cabinet. No guaranteed uptime SLA in the true sense.

FTTP (Fibre to the Premises) — Full Fibre

Full fibre runs all the way to your building, eliminating the copper last mile. Speeds can reach 1 Gbps or more, with symmetrical or near-symmetrical upload/download. Availability has expanded significantly across Greater Manchester in the last two years, with providers like BT Openreach, CityFibre and Virgin Media Business rolling out coverage.

Good for: Businesses with growing cloud workloads, regular video conferencing, remote teams, or file-heavy workflows. Often excellent value for what you get.

Limitations: Still not universally available in all areas. Business-grade FTTP products with proper SLAs are priced differently from consumer “full fibre” packages — make sure you’re comparing like for like.

Leased Line (Ethernet Dedicated Internet Access)

A leased line is a dedicated, uncontended connection — meaning you’re not sharing bandwidth with anyone else. It runs directly from your premises to the network, delivering symmetrical speeds (typically 100 Mbps to 10 Gbps) with a contractual uptime guarantee, often 99.9% or higher, and a fix time SLA if it goes down.

Good for: Businesses where downtime is genuinely costly, where upload performance is critical, or where multiple sites need reliable private connectivity. VoIP-heavy operations, data centres, financial services.

Limitations: Higher cost than broadband — typically £200–£600/month depending on speed and location. Longer install lead times. Requires a structured business case, but for the right business, it pays for itself quickly in avoided downtime.

SD-WAN (Software-Defined Wide Area Network)

If you have multiple sites or a mix of connectivity types, SD-WAN lets you intelligently manage traffic across all of them — prioritising business-critical applications, balancing load between connections, and automatically routing around failures. It’s increasingly accessible for smaller businesses and can turn a combination of broadband connections into something that behaves like a leased line in terms of resilience.

Good for: Multi-site businesses, businesses combining FTTP with a 4G/5G failover, or anyone who needs better control over how their network bandwidth is used.

4G/5G as Primary or Failover

Mobile connectivity has become a genuine option for business internet — either as a primary connection in locations where wired options are limited, or as a failover that kicks in automatically if your main line goes down. With 5G now available across large parts of Manchester city centre and surrounding areas, speeds can rival or exceed standard FTTC broadband.

Good for: Temporary sites, pop-up offices, buildings where wired install is complex, or as an automatic failover to eliminate single points of failure.

The Case for Connectivity Resilience

One of the most impactful changes any Manchester business can make to its connectivity is adding a failover. A second line — even a 4G router on standby — means that if your primary connection goes down, your business switches over automatically. Staff keep working. VoIP calls keep routing. No one’s sitting waiting for an engineer.

For a business with 10 people, an hour of downtime during a working day might cost £300–£500 in lost productivity, missed sales calls, or delayed work. A 4G failover costs £30–£50 a month. The maths doesn’t take long.

When we assess a new client’s connectivity, resilience is always part of the conversation — not just raw speed.

How Connectivity Affects the Rest of Your IT

Business connectivity isn’t isolated from the rest of your IT. It affects everything:

• Microsoft 365 and cloud apps — Teams calls, SharePoint file syncing, and Exchange email all need reliable upload bandwidth. A slow or unstable line makes your cloud investment perform poorly.
• VoIP phone systems — VoIP is sensitive to latency and packet loss. A congested broadband line can make calls choppy or drop them entirely. Proper QoS (Quality of Service) settings and adequate bandwidth are non-negotiable.
• Remote working — VPN performance and remote desktop sessions depend heavily on upload speed. If your office connection has slow upload, remote workers connecting in suffer for it.
• Data backup — Cloud backup solutions push data out of your network. Without adequate upload bandwidth, backup windows run long, and in a worst case, backups fall behind and you’re not protected.
• Security — Firewall performance, threat intelligence feeds and cloud-based security tools all depend on a stable, well-managed connection.

What to Look for When Choosing a Business Connectivity Provider

Not all business broadband products are equal, even when the speed numbers look similar. Here’s what to check:

• SLA for repair times — How quickly will they fix it if it goes down? Consumer ISPs might say “within 3 working days.” A business-grade product should be hours, not days.
• Contention ratio — How many other businesses are sharing your bandwidth? 1:1 (uncontended) is a leased line. 20:1 is typical business broadband. 50:1 or higher is essentially consumer grade.
• Static IP addresses — Are they included? How many? Essential for VPN, hosted services, and remote access.
• Hardware included — Is a managed router included? Who supports it? If the router fails, does your IT company handle it or do you call the ISP?
• Contract terms — Business connectivity often comes in 12–36 month contracts. Understand what you’re signing up for, especially leased lines which have longer provisioning lead times.

How Coretek Helps With Business Connectivity

We don’t just set up computers and sort out your email. Connectivity is part of managed IT support at Coretek — because the best endpoint management in the world is undermined if the network underneath it is unreliable.

We work with a range of connectivity providers and can source, provision and manage your business broadband or leased line as part of your IT contract. That means one point of contact, one monthly invoice, and someone who understands how your connectivity fits into the bigger picture of your IT setup.

We also handle the router and network hardware, configure QoS for VoIP and business-critical traffic, and put failover in place so that a line fault doesn’t take your whole business offline.

If you’re in Manchester or Greater Manchester and you’re not sure whether your current connectivity is fit for purpose — or if you’ve been meaning to look at it and never quite got around to it — give us a call. We’ll audit what you’ve got, tell you straight what we think, and give you options without the hard sell.
