Network Delivery

Making light work

What we do

We’ve been building fibre, copper and coaxial networks for over 25 years. During this time, we’ve experienced the transition from traditional Copper and HFC architectures to state of the art superfast fibre broadband networks bringing fibre delivery directly to the home.

Our ability to adapt to change over several decades in a fast-moving technology sector is crucial. It means that we can combine extensive experience (about 12,000 man years) with the flexibility to organise the right skills, in the right volume, at the right time. We are a true turnkey specialist and we take pride in supporting you to get your project completed efficiently, and on time.

Civils Construction

The environment in which we now build networks for customers has changed enormously. Our team operate where there is greater emphasis on stakeholder engagement and more consideration to our environmental impact, both of which enhance the potential for future customer growth. As network expansion typically becomes more rural, working smarter with new technologies and new materials, we support our customers in adapting best practice to reduce build cost per home. Overlaying our experience to support major build programmes is an integral part of how we deliver our services.

Network build has been a core skill-set for Avonline since the early 90’s. We offer a well-developed operational structure, refined to build high quality networks, delivered to the best current safety and legislative standards across the UK. We mix experienced teams with well-managed sub-contractors and a leadership team that has been at the forefront of network delivery in the UK for thirty years.

Building modern networks requires a range of techniques. From traditional trenching methods using conventional excavators to narrow and micro trenching, to heavier trenching methods using top cutters and directional drilling. This is where our unrivalled mix of experience and flexibility means that we can deliver the right capabilities on any type of network build.


Cabling and activation is our oldest and most established skill-set. We have delivered copper, coaxial and fibre cabling across all the major UK fixed line networks. Our teams are highly skilled in all aspects of underground and overhead techniques even landing transatlantic submarine cabling. Our teams are comfortable across a full range of skills including terminating, jointing and testing, whether on planned works on in demanding situations like disaster recovery.

Most of our cabling work is carried out and managed by our experienced in-house teams. With UK bases in Bristol and Northumberland, we provide national coverage for major cabling programmes and are trusted partners on the UK’s largest and most complex networks.

Fibre Networks

We pull it, we blow it, we hang it, we joint it, we test it – and we love it.

With an unbroken run of over 25 years of deploying, upgrading and repairing fibre networks, our senior team are widely respected and support clients across the UK. We are often to be found collaborating on new technology programmes supporting trials and new ways of building networks from overhead and underground FTTP PON/GPON networks to supporting re-segmentation programmes on copper networks to provide faster broadband speeds.

Copper Networks

Our copper work has traditionally been focussed on the complex and demanding BT network. Since the mid ‘90s we have worked with most major BT partners like Pirelli, Ericsson, Fujitsu, Carillion Telent and Morrison Utility Services as well as delivering programmes directly.

Like a famous theme song, we work underground and over ground, supporting street works and the overhead network. With such a diverse range of network architecture, experience and understanding of every aspect of this specialised environment is crucial. It enables us to complete complex work efficiently and correctly every time and for our teams to operate safely in situations where application of H&S standards is paramount.

Today Avonline teams operate across the UK, supporting network cabling, cabinet and mux work and new technology pilots like G-Fast.

Our clients

From just a few thousand pounds to almost quarter of a billion, the range and scale of our customer base and the work that our teams have delivered is unusually broad.  We’ve highlighted just some of the great customers that we are proud to have worked with over recent years.


As an approved Sky Homes installer (ASHA), our work today focuses on providing the latest Sky Q (4K capable) head-end upgrades across our public and private sector MDU portfolio. We also build, service and upgrade standard Sky specification IRS for all MDU portfolios.

Virgin Media

We have partnered with Virgin Media and its forebears now for over 25 years. Our teams have been instrumental in the original cable network design and delivery. We built and activated networks reaching millions of UK premises, connected services into even more homes and businesses and have supported a wide variety of programmes right through to the amazing Project Lightning programme.

BT Openreach

Working both directly and through an extended history of tier 1 partners, Avonline teams have completed an enormous range of services on the BT network. Indisputably, this is a network that simultaneously requires very detailed understanding of one of the oldest and most complex national networks alongside state of the art FTTP network build. Today we operate North and South on a range of copper and fibre programmes including the BDUK backed rural fibre programme.

Carillion Telent

The highly respected SPV created to service Openreach on a nationwide basis. Our teams have supported CT work across all aspects of the BT network including the latest G Fast trials.

Morrison Utility Services

Our partnership with MUS goes back to 2010 when we collaborated on a great Joint Venture bid for a major programme of works. We have gone on to deliver work-streams of a varied nature, mostly around the BT network across the UK.
