Leased line installation

In the UK, the standard timeframe for installing a new dedicated leased line is around 90 days, regardless of your chosen provider.

Unlike other broadband services, switching leased line providers involves installing a new dedicated fibre optic cable.

This article explores the leased line installation process, explaining the factors involved in the timeline and addressing potential challenges to help you plan effectively.

Key steps for leased line installation

Here, we’ll explain the five key steps in a leased line broadband installation and provide an estimated time frame for each.

Initial quote for a dedicated leased line

Time-frame: 1–2 days

The quotation process for leased line installations involves a desktop review of the distance between a provider’s closest exchange and your commercial property.

Leased line providers use different exchange locations and adjust their proposed leased line broadband prices according to the required length of your dedicated fibre optic cable.

If you proceed with a quote, your provider will issue a leased line business broadband contract for your review and signature.

All leased line contracts are subject to a site survey. Where unforeseen additional costs are identified during installation, the provider retains the right to propose an Excess Construction Charge or cancel the agreement entirely.

Site survey

Timescale: 1-2 weeks.

Your business broadband provider will conduct a site survey to assess the feasibility of laying your dedicated bearer line (the fibre optic cable) from the exchange to your commercial property.

The site survey will evaluate:

The requirement to obtain any wayleaves.
The usability of existing fibre ducts between the exchange and your commercial property.
The length and difficulty of any micro trenching required between the nearest duct and your commercial property.
Agreement on the Optical Network Terminal (ONT) position within your property.

If any unforeseen issues arise during the survey, your provider may propose an Excess Construction Charge. We’ve included a list of common problems below.

Assuming no unforeseen problems with your leased line installation, your provider will proceed directly to the infrastructure work.

Infrastructure work

Timescale: Minimum 1 month.

Your dedicated bearer line will be connected to the exchange and deployed through the underground ducting to your commercial property.

Where necessary, micro trenching will be used to connect the nearest fibre duct to the entry point of your commercial property.

A small hole is typically drilled in the wall of your property to allow access to the interior of the building.

Equipment installation

Timescale: 1-2 weeks

Your chosen business broadband provider will install an Optical Network Terminal (ONT) and a business broadband router, which connect to the terminating point of your dedicated leased line cable.

Network switches and mesh network equipment are typically not included in a leased line contract. It’s important for your IT team to consider the compatibility of existing hardware as part of the installation process.

Testing and go-live

Timescale: 1-2 weeks

Your provider will conduct testing to verify that your connection delivers the promised speed and latency performance.

Assuming these tests go smoothly, your leased line will be fully activated. Once your connection goes live, we recommend testing the performance against your agreed SLAs.

If your business requires additional speed, the installed bearer line can typically support a wider bandwidth. To scale your broadband, speak to the account manager at your leased line provider.

Delays with leased line installations

The following problems can result in significant delays, cost increases, or even the cancellation of a leased line installation.

Where these problems are identified, your leased line broadband provider may propose an Excess Construction Charge to cover the additional costs.

If an Excess Construction Charge is proposed, you have the option to accept it or cancel your leased line order free of charge.

Wayleave agreements

A wayleave agreement is a legal contract that grants a telecoms provider permission to lay fibre optic cables over, under, or on private property.

A common scenario where a wayleave is required arises when a business renting an upper floor of a building needs agreement from the building owner to lay a dedicated fibre cable through the lower floors.

When a wayleave is required, your leased line provider will draft a wayleave application and typically propose a standard set of rates for the wayleave rights.

Obtaining wayleaves can result in significant delays if the third party is unwilling or unable to agree to the proposed wayleave promptly.

Lack of useable fibre ducting

The bearer line will travel most of the distance through existing fibre ducting installed beneath roads in urban areas.

An initial leased line site survey will assess the usability of the ducts between the exchange and your commercial property.

If a duct is unusable or has yet to be constructed, a road closure will be required to build the new duct.

This will significantly increase both the cost of the leased line and the time required to complete the installation.

SLAs for business broadband installation

Some broadband providers offer a specific service level agreement (SLA) for leased line installation.

A typical SLA includes a committed delivery date set after the site survey. If the delivery date is not met, the provider may offer a percentage discount on the delivery charge.

We recommend enquiring about leased line installation SLAs when initially receiving quotes for a leased line business broadband service.

Preparation for a leased line installation

Our business broadband experts have three recommendations for preparing for a new dedicated leased line installation.

Early communication with landlords

If your property is leased or surrounded by private land, your leased line provider will likely need to negotiate a wayleave agreement.

We recommend communicating with your landlord early to explain the purpose and benefits of the leased line. This can help smooth the way for your leased line provider to conduct wayleave negotiations.

Identify access points

Designate a secure and accessible comms room for the leased line termination equipment. Ensure that the designated room has an adequate power supply and is well-ventilated.

We recommend clearing the comms room before the initial site survey and installation.

Plan for temporary connectivity

The leased line installation process typically takes 90 days but can take much longer if issues arise.

It’s important to plan for alternative connectivity during the installation process. Typical options include:

SoGEA business broadband: Installations are usually quick as this service uses copper cables installed at most commercial properties.
5G business broadband: A 5G-enabled business broadband router can provide fast broadband without requiring physical installation.
