Network upgrades boost average broadband speeds

Mouse and speedometerThe average UK home broadband speed has increased to 9.0Mbit/s, driven by the move to new ‘superfast’ services, Ofcom research reveals.   

That is 2½ times faster than the average speed of 3.6Mbit/s when Ofcom first began its speeds research in November 2008.   

Ofcom’s latest research – which was conducted in May 2012 – now includes some new ‘superfast’ packages, including Virgin Media’s ‘up to’ 60Mbit/s service and BT’s Infinity 2 ‘up to’ 76Mbit/s service, the launches of which have contributed to the rise in average speeds.   

The continuing trend of increasing speeds recorded in the research confirms that consumer migration to faster services is gathering momentum.    

While some consumers actively choose to upgrade to superfast broadband packages to achieve higher speeds, many are benefitting from improved speeds as a result of internet service providers’ (ISPs’) network upgrades, at little or no additional cost to consumers.   

In May 2012, over two-thirds of UK fixed-line residential broadband users (68%) were on packages with advertised speeds above ‘up to’ 10Mbit/s, an increase from 48% in May 2011.   

The proportion of broadband connections which are superfast (i.e. they have an advertised speed of ‘up to’ 30Mbit/s or above) has increased in recent months with the launch of new superfast packages. By May 2012, 8% of residential broadband connections were superfast, compared with 5% six months previously and 2% in May 2011.   

Residential superfast broadband connections are also getting faster, with average speeds increasing from 35.5Mbit/s in November 2011 to 35.8Mbit/s in May 2012.*   

Network upgrades to meet the need for speed

The noticeable overall improvement in speeds is, in particular, the result of ISPs upgrading their broadband networks.   

BT’s upgrade of its copper ADSL network, for example, has seen many customers moved from ADSL1 technology to the faster ADSL2+ technology, while BT’s upgrade of its fibre to the street cabinet (FTTC) service has seen an ‘up to’ 76Mbit/s service launched alongside its ‘up to’ 38Mbit/s service.   

Similarly, in February 2012, Virgin Media started to double the speeds of most of its broadband connections, increasing the top speed of its fastest package to ‘up to’ 120Mbit/s.   

Comparisons between ISPs’ download speeds

Of the 12 ISP packages included in the report, Virgin Media’s ‘up to’ 100Mbit/s service was the fastest, with the research revealing average actual speeds of 88.3Mbit/s over a 24 hour  period.    

Of the other superfast packages included in the research, the average download speed on BT Infinity’s ‘up to’ 76Mbit/s service was 58.5Mbit/s*, compared with Virgin Media’s ‘up to’ 60Mbit/s at 55.9Mbit/s.  

BT’s ‘up to’ 38MBit/s package achieved speeds of 32.2Mbit/s* whilst Virgin Media’s ‘up to’ 30Mbit/s service had average speeds of 30.1Mbit/s.  

During busy peak periods, a higher proportion of Virgin Media cable customers experienced speeds of less than 90% of their average maximum speed, compared to BT Infinity fibre customers. 


Note: These ranges reflect the speeds that would be achieved 95 times out of 100 if the exercise was repeated with different panellists. If the range of two operators overlap, then these operators offer comparable performance. They are not a description of the range of speeds actually measured.

Fastest upload speeds

Whilst download speed is the most important single measure in determining broadband performance, our research also considers other factors including upload speeds.   

Upload speeds can be an important consideration, especially for those consumers looking to share large files or use real-time video communications.   

The research found that BT Infinity’s ‘up to’ 76Mbit/s service delivered the highest upload speeds of all the packages, averaging 15.6Mbit/s.   

Among the ADSL2+ packages included in the research, O2/Be’s ‘up to’ 20/24Mbit/s service provided the fastest average upload speeds at 1.1Mbit/s.   

Broadband Advertising

In April this year, guidance on the use of speed claims in broadband advertising published by the Committee of Advertising Practice (CAP) and the Broadcast Committee of Advertising Practice (BCAP), came into force.   

The guidance states that advertised speed claims now have to be achievable by at least 10 per cent of the relevant ISP’s customer base.   

Many ISPs have therefore changed the way they advertise their broadband services.   

For example, ADSL2+ services, which were previously often promoted using the technology’s maximum theoretical speed of ‘up to’ 24Mbit/s (which was rarely achieved in practice), are now frequently being advertised as ‘up to’ 16Mbit/s.   

Some ISPs have moved away from promoting their services primarily on the basis of speed focussing instead on price, or added value features such as free security.   

Code of Practice

In July last year, a revised and strengthened Voluntary Code of Practice on broadband speeds came into force.   

This requires ISPs to give more accurate estimates of a prospective customer’s expected maximum speed in the form of a range. In addition, it seeks to ensure that, where possible, customers’ speed-related problems will be resolved by their ISP.   

If this is not possible, then customers whose speed is significantly below the estimated access line speed range have the ability to leave their provider within three months of the start of their contract without penalty. All of the UK’s largest ISPs are now signatories to the Code.   

Ed Richards, Ofcom Chief Executive, said: ‘Our research shows that the move to faster broadband services is gathering momentum. Consumers are benefitting from network upgrades and the launch of new superfast packages, giving them faster speeds and greater choice.   

‘We are continuing to work with the advertising code-writing bodies and ISPs to ensure that speeds advertised reflect actual speeds experienced, to allow consumers the ability to make informed decisions when shopping around to find the most suitable package.’

If these results are excluded:   

  • The average UK residential actual broadband speed in May 2012 increases to 9.1Mbit/s.
  • The average actual speed of residential UK superfast broadband connections rises from 35.8Mbit/s to 36.9Mbit/s
  • The average actual speed of residential FTTC connections rises from 31.6Mbit/s to 34.0Mbit/s
  • The average download speed on BT Infinity’s ‘up to’ 76Mbit/s rises from 58.5Mbit/s to 60.7Mbit/s
  • The average download speed on BT Infinity’s ‘up to’ 38Mbit/s rises from 32.2Mbit/s to 34.7Mbit/s
