Business broadband in London, built for offices that can't afford to go offline
A residential-grade broadband connection wasn't built for a business running cloud tools, VoIP calls and remote access every working hour, and London's dense mix of office buildings, shared floors and older properties makes getting connectivity right even more important than in most cities. We supply and manage business-grade internet for office premises across London — from FTTP and Ethernet leased lines through to bonded and failover configurations that keep you online even if one connection drops. Every install is matched to what your business actually does online: a professional services firm running VoIP and cloud applications needs a different profile to a retailer processing card payments or a creative agency transferring large files between studios.
Connectivity is also the foundation everything else depends on. Microsoft 365, VoIP phone systems, cloud backup and Azure cloud servers are only as reliable as the line carrying them — a fast connection that drops for ten minutes every afternoon will make all of those feel unreliable, even though the fault sits upstream. Getting business broadband right in London means thinking about resilience as much as raw speed, particularly in older buildings across the City and West End where cabling infrastructure can be more complex to work with than in newer developments.
Being based in the City of London ourselves means we understand the practical realities of getting connectivity installed here — building management approval processes, shared risers in multi-tenant buildings, and lead times that can vary significantly between a modern development in Canary Wharf and a period building near Bank or Liverpool Street. We manage the whole relationship with your connectivity provider on your behalf — orders, faults, upgrades and renewals — so your team has one point of contact rather than a separate ISP account that only picks up the phone once you're already a paying customer with an open fault ticket.
Business Broadband Serving London
London's office market spans some of the most connectivity-dependent sectors in the UK. The City of London and Canary Wharf house financial and professional services firms running latency-sensitive trading systems and constant video conferencing; the West End and Soho are home to media, advertising and entertainment businesses moving large creative files daily; Shoreditch and the wider Tech City area around Old Street host a dense concentration of software and SaaS start-ups; and retail and hospitality businesses across every borough depend on card payment connectivity that simply cannot fail during trading hours. Each of these puts different demands on a broadband connection, and a one-size-fits-all package rarely serves any of them well.
Working Around Building Complexity
Many London offices sit in multi-tenant buildings, listed properties or shared floors where installing a new leased line means coordinating with building management and other tenants, not just the connectivity provider. We manage that coordination as part of the install rather than leaving it for your team to chase.
Based Here, Not Just Serving Here
As a City of London business ourselves, we can attend site for surveys, installs and hardware issues directly, without the delay and cost of dispatching an engineer from elsewhere in the country.
Resilience for High-Density Areas
Shared infrastructure and high building density mean a single fault can affect multiple tenants at once in parts of central London. We design failover and bonded configurations specifically with that risk in mind, rather than assuming a single connection is enough.
What we manage for you
The connectivity work most London businesses would rather not handle themselves.
Our approach to business broadband in London
Right-Sized From the Start
We assess your bandwidth needs, user count and what actually runs over the line — VoIP, cloud backup, card payments — before recommending a connection type.
Managed for the Life of the Contract
We handle provider liaison, building management coordination and renewals on your behalf, so a dropped connection means one call to us, not a hold queue with your ISP.
How it works
From first conversation to a live, monitored connection.
1
Site Survey
We check what's available at your London premises and review current usage, applications and any existing connectivity.
2
Recommendation
We recommend the right connection type and resilience level, with transparent, plain-English options.
3
Install
We project-manage the order and installation, including building management coordination where needed.

Monitor & Support
24/7 monitoring and ongoing fault management, backed by our 99% SLA guarantee, for the life of your contract.
London businesses come to us when
Video calls and VoIP conversations regularly break up or drop, especially during peak hours
A single broadband outage has previously taken the whole office offline for hours
They're paying for a leased line but have no idea whether it's actually the right product for their usage
They're moving into a new London office and need connectivity specified and installed without the hassle
Faults with their current ISP take days to get acknowledged, let alone resolved
Card payments intermittently fail because the connection can't be trusted at peak trading times
Building management is asking for a technical point of contact they can deal with directly for cabling work
They're moving more systems to the cloud and know their current connection won't keep up
They want one provider managing connectivity, IT support and cloud systems instead of three separate suppliers
Why choose Cloudswitched for business broadband in London?
We're based in the City of London ourselves, so surveys, installs and hardware issues get a genuine on-site visit without the delay of dispatching an engineer from elsewhere in the country.
We specify connectivity around what your business actually does online, not the fastest headline speed a provider wants to sell you.
24/7 monitoring and our 99% SLA guarantee mean connectivity problems get caught and escalated before your team has to report them.
We manage building management coordination and provider relationships directly, so faults, renewals and cabling approvals are one call to us rather than a queue with the ISP or your landlord.
Connectivity sits alongside our wider managed IT support, network administration and cloud services, so if a VoIP call quality issue turns out to be a network configuration problem rather than the line itself, the same team can fix it.
And should your needs change as you grow across additional London floors or a second site, we review and adjust your connectivity rather than leaving you locked into a spec that no longer fits.

Why Cloudswitched for connectivity?
Connectivity is infrastructure, not an afterthought. Here's what sets us apart.
Based in the City of London
Genuine on-site coverage for surveys, installs and hardware issues, not an engineer dispatched from elsewhere.
24/7 proactive monitoring
Connections are watched around the clock, with faults flagged before your team notices anything wrong.
99% SLA guarantee
A written service level commitment, so uptime is something you can plan around, not just hope for.
Building management handled

Connectivity plus IT support
Networking, VoIP, cloud email and managed IT support sit under the same roof, so problems don't get passed between suppliers.
Failover that actually works
Bonded and 4G/5G failover options are tested at install, not assumed to work when you eventually need them.
No hidden markups
We're upfront about what's provider cost and what's our management fee, so quotes are easy to compare.
Plans that scale with you
Adding a second London floor or site is a conversation, not a renegotiation from scratch.
No long lock-in surprises
Contract terms are explained clearly before you sign, so there's nothing awkward buried in the small print later.
Business broadband vs consumer broadband vs leased lines
Consumer-grade broadband is cheap but comes with no service level agreement, shared capacity at peak times, and support that treats a business outage the same as a household one. Business broadband adds a proper SLA and faster fault response, but a single connection is still a single point of failure. A dedicated leased line offers guaranteed, symmetrical bandwidth and the strongest SLA, at a higher monthly cost that's usually justified once a business genuinely depends on its connection for VoIP calls, card payments or cloud-hosted systems. For many London businesses, particularly in older buildings where a fresh leased line install can take longer to arrange, the right answer sits between the two: a strong business broadband or FTTP connection with 4G/5G failover, giving leased-line-style resilience without leased-line pricing or lead times. We'll tell you honestly which category your business actually needs rather than defaulting to the option with the highest margin.
About London's office market
London remains the UK's largest and most connectivity-dependent commercial centre, spanning the historic financial district of the City of London, the modern towers of Canary Wharf, the media and advertising cluster around Soho and the West End, and the fast-growing Tech City scene around Shoreditch and Old Street.
Sector mix: Financial and professional services in the City and Canary Wharf run latency-sensitive systems and constant video conferencing; media and creative agencies in the West End and Soho move large files daily; software start-ups around Shoreditch depend on reliable cloud access; and retail and hospitality across every borough need card payment connectivity that simply cannot fail.
Building complexity: London's mix of period buildings, listed properties and multi-tenant floors means connectivity installs often involve coordinating with building management as much as the connectivity provider itself — something we handle as standard, being based in the City ourselves.

Frequently Asked Questions
Got questions about business broadband in London? We've answered the most common ones below.
How much does business broadband cost in London?
Pricing depends on connection type, what's available at your premises and how much resilience you need. We'll survey your site and provide a tailored, transparent quote rather than a generic price list.
Are you actually based in London, or is this remote support?
We're genuinely based in the City of London, so surveys, installs and hardware issues get a real on-site visit from our own team, not an engineer subcontracted from elsewhere.
How long does installation take in a London office building?
FTTP and standard business broadband typically install within a few weeks of ordering; leased lines can take longer in period or listed buildings where cabling and building management approval add time. We manage the timeline and keep you updated throughout.
Do I need a leased line, or is bonded broadband enough?
It depends on how much your business depends on the connection. A leased line gives dedicated, symmetrical bandwidth with the strongest SLA; bonded broadband gives leased-line-style resilience for less, often with a faster install in complex London buildings.
What happens if our connection goes down?
With 4G/5G failover or a bonded configuration, traffic automatically shifts to the backup connection. Our 24/7 monitoring flags the fault and we manage the repair with your provider on your behalf.
Can you deal with our building management directly?
Yes, we coordinate cabling access and installation approval with landlords and building management as part of the project, so your team doesn't have to chase that separately.
Will you manage our existing connection, or only new installs?
Both. If you already have broadband or a leased line in place, we can take over monitoring and provider management without needing to reinstall anything.
Does this work alongside our VoIP phone system?
Yes, we size connections with VoIP call quality specifically in mind, and can advise on or manage your VoIP phone system alongside your connectivity.
