Leased lines: What are they, and should I get one?

Leased line

When it comes to broadband for your business, you’re not short on options. There’s ADSL, fibre optic broadband, FTTP, enterprise broadband - and leased lines.

What's a leased line?

A leased line is a dedicated broadband connection. Rather than sharing a broadband line with your neighbours - like you do with any other kind of broadband - you rent a single line all to yourself. They're generally used by businesses with high-powered broadband needs.

What kind of broadband does my business need?

With a standard shared line, the speed and reliability of your broadband can fluctuate as other users go online and eat up bandwidth. It can also mean slower speeds in general, depending on the contention ratio in your area. This isn't an issue with a leased line, however - since it's entirely yours to use, speeds are steady and it's more secure.

Speeds on a leased line are available from 10Mb all the way up to 10Gb (10,000Mb), and they're symmetrical. In other words, your download and upload speeds are the same - which is incredibly helpful if you need to upload data, host a website, use a VPN, or let remote workers use your office's servers.

It'll also give you low latency (lag) - essential for things like making video calls and accessing data remotely. And in most cases, you'll get 24/7 customer care and priority fault fixes when things go wrong.

Do I need a leased line?

As broadband goes, a leased line is a very costly option. We're talking a few hundred pounds per month, plus anything from £500-£1,500 for installation.

However, if a high-quality broadband connection is absolutely vital to your business - or would give it that extra oomph - it's worth every penny.

Consider leasing a line if your workplace…

  • Is a very big office with dozens of people to connect
  • Needs to transfer large amounts of data, all the time
  • Does financial trading
  • Runs a big website
  • Needs guaranteed, reliable internet for many people, 24/7
  • Uses VoIP a lot

Crunch the numbers and work out if it's the best option for your company. If not, take a look at the rest of our business broadband deals.

For residential broadband, it isn't worth getting a leased line at all - though if you can afford it and want guaranteed broadband for your home, then hey, we're not going to stop you.

Pros of getting a leased line

  • It can give you positively lightning-fast downloads, with symmetrical upload speeds - BT offers speeds up to 10Gb, in fact.
  • It's not shared with anyone, so speeds are steady and won't fluctuate.
  • With most leased line packages, you can change your bandwidth whenever you want - meaning you can pay less in quieter months.
  • Latency is low.
  • It's more secure and private than a shared line.
  • You're guaranteed to get a connection at the speeds you want wherever you are, with certain providers.
  • You'll get a service level agreement and priority fixes for faults.
  • It often comes with static IP addresses.

Cons of getting a leased line

  • It's expensive.
  • Like, really expensive.
  • It gets even more expensive if your workplace is a long way away from the nearest exchange.
  • It also takes longer to install - it can be up to three months, whereas regular business broadband can go live in a fortnight.
  • On that note, a leased line needs to be physically installed, which is hassle.
  • A leased line package doesn't usually include landline phone plans - you'd need to sort those out separately or get them as an add-on.
