When deciding whether or not to upgrade your best-effort internet to a dedicated connection, it’s important to understand the pros and cons of dedicated internet. After all, once you’ve discovered which type of connection you require, you can begin comparing suppliers. To aid with your decision, let’s take a look at the benefits and drawbacks of this type of internet connection.

Do you need Dedicated Internet?

Firstly, let’s make sure we know what dedicated internet is. Like dedicated hosting, dedicated internet access (DIA) is a private internet connection solely used by your business. You will benefit from from guaranteed upload and download speeds and a completely unique service.

DIA provides your business with reliable and predictable performance at any given time, with any amount of users. When you buy this internet circuit, it comes with a guarantee to receive the bandwidth you purchased. For example, if you purchase a 20MBps circuit, you will receive 20MBps of internet to segregate and section off as you please rather than dealing with fluctuations in upload and download speed. Whether it be for VoIP, CRM or streaming, your 20MBps is at your disposal and not going anywhere, even during peak periods.

Typical use cases for this type of internet are usually in a business context. According to research from Beaming, 149 million hours of downtime was suffered due to poor internet connections in 2016. This equates to £12bn in lost productivity. So, if part of or all of your business is reliant on internet connectivity, you should be considering dedicated internet.

Pros of Dedicated Internet


The first, most significant advantage is that this internet connection is unique to you and your business so there are no other businesses or homes using this connection. Unlike home connections and shared business lines, the only way to connect is via the links into your building. Once received into your building, it’s up to your IT team to make the connectivity accessible to users and applications.


With a private connection, you have the ability to allocate bandwidth as you see fit. Once you have identified which apps consume the most bandwidth, or are most heavily used, you can assign more bandwidth to them as required. For example, it’s a well known fact that Unified Comms traffic only needs 100kbps per user. That equates to 10mb per 100 users. However, once you know how many concurrent calls there will be at any one time, this bandwidth requirement is reduced. If only 20 people are ever on a call at the same time, you only need allocate 2MBps.


Unlike traditional internet connections, dedicated internet doesn’t come prepackaged. With ADSL and FTTC connections, you are subscribing to packages of 20MBps or 80MBps download speed. A major pro of dedicated internet is that you can request as much or as little bandwidth as you require. A line will be installed and you simply subscribe to the amount of bandwidth you genuinely need reducing your over-payments for internet you don’t need.

Cons of Dedicated Internet

Premium Service

This is a premium service, therefore is more expensive that traditional internet access. This may be a shock for first time buyers, but when you fully understand the benefits, the total cost of ownership and tangible return on investment becomes easier to understand.


Once the bearer for your line has been installed, you may feel that you aren’t using your connection for optimum performance. For example, if you subscribe to a 50MBps connection, this requires a 100MBps bearer to be installed. Bearers typically come in 10MBps, 100MBps, 1GBps or 10GBps. So using 50MBps on a line with 100MBps potential can seem underwhelming. Talk to your provider about have best to utilise the line you purchase.

Dedicated Internet FAQs

How long will it take to install DIA?
Dependent on location, DIA lines take up to 90 days to install. Most are quicker if existing infrastructure already exists. Some take longer if council or landlord permission is required for your building.

What is the best router for DIA?
The best router is totally dependent on your requirements. What you need to do with your connectivity will drive the best router for you. Generally, the market leaders in dedicated access routers are Juniper and Cisco. Speak to your service provider to work out what is compatible with their connection, and best for you.

Is a dedicated line truly dedicated to just my business?
Yes! Hard to believe many years about but dedicated internet is just that.
