Can I Get a Leased Line at My Business Address?

How do I check if a leased line is available at my address?

The only reliable way is a multi-carrier postcode check. A single provider's tool only shows its own network, so it misses cheaper or faster routes next door. AMVIA runs your address against Openreach, CityFibre and Virgin Media Business together and returns a like-for-like comparison.

Availability is not binary. Almost every UK address can technically take a business leased line — the question is what it costs and how long the build takes. A postcode check tells you three things at once:

• Which carriers already have fibre serving or passing your building
• Whether you fall inside a ready-to-connect footprint or need new civils
• The realistic monthly rental and one-off install for each route

If you are still weighing the technology itself, what a leased line is explains why a dedicated, uncontended circuit behaves differently from shared broadband.

What determines whether a leased line reaches my area?

Coverage is driven by national fibre rollout and by the distance between your building and the nearest carrier fibre. The UK fibre footprint has grown fast, which widens the number of addresses that can be served quickly and cheaply.

Total FTTP coverage reached 79.5% of UK premises (approximately 26.7 million premises) in Q3 2025, according to Ofcom's Connected Nations programme (ofcom.org.uk). Gigabit-capable broadband now covers 87% of the UK as of 2025, up from 84% in 2024. Openreach is investing up to £15 billion to expand full fibre coverage to 25 million premises by December 2026.

That rollout matters because a leased line is delivered over fibre. Where full-fibre infrastructure already passes your premises, install is faster and excess construction charges are far less likely. Where it does not, you can still get a circuit — it just needs a build.

What if there is no fibre near my premises?

You can still get a leased line; the carrier simply builds fibre to your door. That construction is priced as a one-off and does not change your ongoing rental, so the dedicated bandwidth you signed up for stays the same.

Excess construction (ECC) adds a one-off charge — typically £1,000–£10,000 depending on distance — with unchanged monthly rental. The figure depends on how much trenching, ducting or wayleave work is needed between the nearest fibre point and your building. AMVIA gets these costs quoted up front so there are no surprises after you sign.

For sites where any build is too slow or too costly, a dedicated internet access circuit on an alternative carrier route is often the answer. The point of a multi-carrier check is to find the route with the lowest combined cost, not just the first one that returns a result.

How does availability differ between carriers?

It differs a lot. Coverage, install speed and price each vary by carrier and by street, which is exactly why a single-provider quote rarely gives you the best deal. The table below shows the broad pattern AMVIA sees across UK business postcodes.

A leased line typically delivers a 99.99% uptime SLA regardless of which carrier delivers it, so the decision comes down to coverage, lead time and total cost. For a full breakdown of what drives the monthly figure, see the leased line cost guide.

If you are deciding whether a dedicated circuit is even the right call versus shared connectivity, leased line vs broadband sets out the trade-offs in plain terms.

How long does installation take once it is confirmed?

Where fibre already serves your building, expect roughly 30–90 working days from order to live. Where new civils are required, the wayleave and construction stage extends that timeline, sometimes considerably. The postcode check flags which scenario applies before you commit.

The slowest part is rarely the technology — it is wayleaves (legal permission to run fibre across land you don't own) and any street works. Getting these moving early is where a provider that chases the carrier daily earns its keep.

What should I do about connectivity while I wait?

Order a leased line for the long term, but don't leave the business exposed in the meantime. A temporary business broadband service or a 4G/5G backup keeps you trading until the dedicated circuit goes live, then becomes your failover.

A leased line is uncontended and resilient, but no single circuit is immune to a fibre cut. Pairing it with backup connectivity gives you a second, independent path so an outage on one line doesn't take the business offline. This is the same security-first thinking AMVIA applies across the stack: one accountable provider, designed for resilience, not just speed. The same principle runs through the UK's own resilience guidance from the National Cyber Security Centre (ncsc.gov.uk) — a connection is only as valuable as the protection sitting behind it.
