Important Note About 21CN and 20CN

If your exchange is enabled for 21CN we will place you on the 21CN packages and pricing structure. As 20CN is being phased out we are actively moving, at our expense, customers to the 21CN platform as quick as possible. Once activeted on 21CN exchange equipment you will benefit from the new pricing and higher speeds.
21CN ADSL 2+
21CN ADSL 2+ (up to 24Mbps)

The 21CN platform with BT Wholesale allows our customers to enjoy download speeds of up to 24Mbps, and upload speeds of up to 832k (compared to 448k on the Home products). The higher speeds are the result of ADSL 2+ technologies. The majority of customers will be able to receive this product, as opposed to the older 20CN solution which is slowly being phased out, however we advise you use our broadband checker to confirm, and see the predicted speed for your line.

20CN ADSL Max
20CN ADSL Max (up to 8Mbps)

A small proportion of exchanges remain only able to serve 20CN solutions from BT Wholesale meaning that you get an ADSL Max up to 8Mbps solution for downstream speeds, and up to 832k upspream. The pricing structure for 20CN connections works differently on a wholesale level, and this is reflected in some of our retail prices. By the end of 2014 all exchanges will have been upgraded to 21CN and we will actively moe you, without additional cost, to this platform once activated.


Downloads Capped
Downloads Capped

Bandwidth is neither unlimited and nor is it cheap for an ISP to purchase and operate a network. As opposed to flooding our products with lots of heavy traffic shaping, bottlenecks and fair usage policies, we clearly state the limits you can download each month. The caps operate on a calendar month, resetting on the 1st.

Unlimited Uploads
Unlimited Uploads

Unlike the downloads, we don't restrict how much you can upload from your connection. This can be ideal especially if you primarily send data (eg off-site backups, or send large attachment emails). None of these activities count towards your monthly usage allowances.

Usage Statistics
Usage Statistics

Our usage statistics are updated every 30 minutes. They can provide a valueable insight into how your connection is performing and how and when it is used. Whether you use this for home or business purposes the results can be very interesting.


Automated Usage Warnings
Automated Usage Warnings

In the event you are predicted to exceed your download quotas our system will send you automated emails with options. These include avoiding additional charges, upgrading the cap, and paying for excess usage. We make the process of upgrading / downgrading accounts incredibly easy.

IPv4 and IPv6 Support
IPv4 and IPv6 Support

Home or Business

Explaining the differences between the connection options

Higher Upload Speeds

Higher Upload Speeds

Regardless of whether you are able to receive the 21CN or 20CN products, the upload speeds you will receive on our business products are significantly higher than those of the Home equivalents. On 21CN they can be up to 1.3Mbps, and the 20CN product delivers up to 832Kbps.

Elevated Traffic

Elevated Traffic

Is an additional paid for service specific to the 21CN connections which we include as standard with our business broadband connection. The elevated traffic service ensures you get at least 3Mbit/s for 90% of the time over the busiest 3-hour period. It ensures your business, and its connection doesn't slow when you need it the most.

Prioritised Support

Prioritised Support

At ICUK we recognise the importance of broadband connections to modern businesses. When you report a fault we will do our best to ensure that it is dealt with as a priority internally to minimise disruption to your business. For the ultimate in response times, not from ICUK, but BT Wholesale, we strongly recommend you consider purchasing the Enhanced Care service to guarantee the quickest responses from our wholesale suppliers.

Standard Prices

Activation & Migration Costs for ADSL

Activation Charges
ADSL Activation £30 If you have a working phone line, but no broadband from another provider, then the activation fee is applicable. BT Wholesale charge to connect the connection. ICUK subsidises this price to lower it to this level.
Fast Track Activation (in addition to activation) £150 If you are in a rush for your broadband connection then there is a fast track order process which is applicable to new activation orders only. Most fast track orders complete within 24-48 hours of them being placed which can reduce the standard activation time by about 4-5 days. This fee is in addition to the standard activation cost.

Migration Charges
Migration FREE The services listed on this page operate using BT Wholesale equipment within the exchange. If you are migrating from another ISP that also uses BT Wholesale to us, then we will cover the £11+VAT migration costs.
Migration from LLU Provider £30 An LLU (local loop unbundling) broadband provider would have installed their own equipment within the local exchange. To move your connection back to BT Wholesale equipment a fee of £40+VAT applies. We subsidise this with a 25% discount.

Modify Charges
Additional Data Transfer (per GB) £1.50 In the event you are predicted to exceed your download limits we would send you warning emails. These will contain the following options:

1. Allow the connection to be speed limited. No additional charges would be applicable for the remainder of the calendar month.
2. Upgrade the data cap to the next level.
3. Pay for an excess data transfer and no be speed limited.

It is the latter option where this would be applicable.
Regrade Speed (one-off) £11 This is applicable if you wish to re-grade a fixed ADSL speed (eg 512k up to 2Mb) or if you wished to switch from 20CN (ADSL Max up to 8Mb) up to 21CN (ADSL 2+ up to 24Mb) as long as these are available to you within the exchange you are connected to.
BT Wholesale Cease Charge £31.12 In the event you cease a broadband connection then BT Wholesale apply this fee to remove broadband from a line. It is not applicable if you simply migrate to another provider. It is, however, applicable if you cease your phone line, or you wish to remove broadband completely off the line. ICUK does not profit from this charge, we simply pass it across at cost.
