How Much Does Dedicated Fibre Internet Cost for Businesses in the UK?

Dedicated fibre internet, also known as leased line broadband, is a premium business service — you can see a full business broadband and leased line comparison here. Unlike standard fibre, it gives your business a private connection. You do not share speed with neighbours or other firms.

The cost reflects this quality. You pay more, but you get steady speed, strong support, and better uptime. For many UK businesses, this trade-off is worth it.

In the UK, most dedicated fibre services start at around £200 per month for lower speeds. High-speed connections for large firms can reach £1,500 per month or more. Prices change based on several key factors, which we explain below.

Dedicated fibre is popular with companies that rely on the internet every day. This includes offices, call centres, online shops, and firms using cloud systems or VoIP phones.

What Affects the Cost of Dedicated Fibre?

The cost of dedicated fibre internet is not fixed. It changes based on your business needs and location. Below are the main factors that affect the price.

Internet Speed

Speed is the biggest price driver. Dedicated fibre offers symmetric speeds. This means upload and download speeds are the same.

Common speed options include:

• 100 Mbps
• 200 Mbps
• 500 Mbps
• 1 Gbps

Higher speeds cost more. A small office may only need 100 Mbps. A large team using cloud tools may need 1 Gbps.

Rural or remote areas may need new fibre lines. This can raise install costs and monthly fees.

For example:

• London offices often get lower install costs
• Rural offices may face higher one-off charges

Installation Costs

Installation is often the hidden cost. It can range from £0 to £10,000+.

Some providers offer:

• Free installation on long contracts
• Reduced install fees during promotions

If fibre needs digging or roadworks, costs rise. Always ask for a full survey before you sign.

Contract Length

Longer contracts usually mean lower monthly prices. Most providers offer:

• 12-month contracts (higher cost)
• 36-month contracts (best value)

A longer deal spreads install costs and reduces risk for the provider.

Service Level Agreements (SLAs)

Dedicated fibre comes with strong SLAs. These promise:

• 99.9% uptime or more
• Fast fix times (often 4–6 hours)
• 24/7 support

Better SLAs increase cost but reduce downtime. For many firms, this peace of mind is priceless.

Provider Choice

UK providers include BT, Virgin Media Business, TalkTalk Business, and specialist suppliers — here’s a guide to the best business internet options in the UK.

Prices vary, but service quality matters more than brand. A cheaper deal with weak support can cost more in lost time.

Dedicated Fibre vs Standard Business Fibre

Many businesses ask if dedicated fibre is worth the extra cost. The answer depends on how you use the internet and whether you’ve taken time to compare business broadband options.

Standard Business Fibre:

• Shared connection
• Lower cost (£30–£80 per month)
• Speeds can drop at busy times

Dedicated Fibre:

• Private connection
• Higher cost
• Always-on speed

If your business depends on video calls, cloud apps, or online sales, dedicated fibre is often the better choice.

“Since switching to a leased line, our calls never drop and our systems run faster,” – UK Office Manager

Is Dedicated Fibre Worth the Cost for Small Businesses?

Small businesses often worry about price, especially when comparing business broadband for SMEs with dedicated fibre. But cost should be weighed against value.

Dedicated fibre can:

• Improve staff productivity
• Support remote work
• Reduce downtime losses

For a small team, even one hour of internet loss can cost more than a month of fibre fees.

A good rule:

• If downtime costs you money, dedicated fibre is worth it.

How to Reduce Dedicated Fibre Costs

There are ways to lower your spend without losing quality.

Tips to save money:

• Choose the right speed (do not overbuy)
• Sign longer contracts
• Compare multiple providers
• Use a business broadband broker

Many UK businesses overpay simply by not comparing deals.

Hidden Benefits of Dedicated Fibre Internet

Beyond speed, there are benefits that are easy to miss.

• Better Security: Private connections reduce risk. This is important for firms handling customer data.
• Scalability: You can upgrade speeds easily as your business grows.
• Future-Proofing: Dedicated fibre supports new tech like AI tools, cloud platforms, and advanced VoIP systems.

Dedicated Fibre Costs Compared to Downtime

Let’s look at a simple example.

If your business:

• Makes £200 per hour
• Loses internet for 5 hours per month

That is £1,000 lost. A £400 fibre line suddenly looks cheap.

Who Should Choose Dedicated Fibre in the UK?

Dedicated fibre is ideal for:

• Growing businesses
• Multi-site offices
• Call centres
• E-commerce firms
• Companies using cloud software

If your internet is mission-critical, this service fits.
