Our VoIP Services in London
Your existing number moves across without your customers noticing a thing. We manage the switch from your current provider and time it so there's no gap in service. Fancy an additional 020 line, or a number from another part of the UK, that's on the table too. More on this in our
020 area code guide.
Define your hours, send calls to the right department automatically, and put people in a queue instead of an engaged tone when things get busy.
Reception and busy desks tend to want a physical handset; everyone else can just use the app. It's all the same system underneath, so which one someone picks up on doesn't matter.
Run one platform across all your London locations, or tie London in with offices elsewhere. Calls between sites are free, transfers are instant, and you get a single invoice rather than one per building.
Round-the-clock cover, weekends and bank holidays included, from a named account manager who's already familiar with how your system's set up.
Not sure what you actually need? We'll look at how your team really uses the phone first, then make a recommendation. Free, no strings attached.
Integrations and Compatibility for London Businesses
Microsoft Teams phone system
If your business already runs Microsoft Teams, calls can be made and received directly inside it using your business numbers, so your team isn't switching between two apps.
More detail:
can VoIP systems integrate with Microsoft Teams.
CRM integrations
When a call comes in, the customer's record can pop up automatically, and outbound calls get logged without anyone lifting a finger. We work with the CRM platforms most UK SMEs are already running:
HubSpot,
Salesforce,
Microsoft Dynamics,
Sage,
Xero,
Zoho,
Zendesk
and
Monday.com, among others. Full list on our
CRM integration page.
Sector-specific software
Beyond general CRMs, we support software built for specific fields too: Clio for legal work,
Dentally, Pearl Dental and
Aerona
for dental clinics, Call Connect GP for surgeries,
EdTech Pro for schools, and
Street.co.uk for estate agents.
Using your existing handsets
If you've already got SIP-compatible handsets, there's a good chance they'll work on our platform without needing to be replaced. Where they won't, we'll flag it upfront during the consultation, not after you've signed up.
Security and compliance
We hold Cyber Essentials certification and comply with UK GDPR. All calls are encrypted while in transit, and our NHS framework approval means we've already met a set of security standards that goes beyond what most providers are assessed against.
The 2027 Switch-Off: What London Businesses Need to Know
What is changing on the UK phone network
Openreach is phasing out the old copper-based PSTN network across the UK, moving analogue and ISDN lines over to digital services carried over broadband instead. Once your local exchange makes that switch, lines running on the old technology simply stop functioning.
Full detail in our
BT switch off guide and
PSTN switch off
guide.
What happens if you do nothing
Businesses still relying on analogue or ISDN lines when their local exchange switches over will find those phones simply don't work anymore. That knock-on effect reaches further than the phone itself alarm systems, door entry systems,lift phones and card machines that run over the same lines are affected too.
How to check whether your line is affected
The quickest test: if you're paying separate line rental or running an ISDN circuit, this applies to you. Already on a cloud system? You're covered. Not sure which one describes your setup?
Check what broadband your London premises can get with our broadband availability checker, or just ask us it's a quick, no-obligation check. Check Whether Your Line Is Affected
Why Professional Installation Matters
Cloud phone systems get marketed as plug and play, and to be fair, they can be. But there's a real gap between a system that's merely working and one that actually suits how your team operates day to day and that gap comes down to how it's set up.
| Feature / Task | Self-setup | Professional installation |
|---|---|---|
| Configuration | You work it out | Designed around how you actually work |
| Call quality | Depends on your network | Network checked and configured first |
| Number porting | You manage it | Handled for you, scheduled to minimise disruption |
| Call routing | Default settings | Built for your department and requirements |
| Training | Online help articles | On-site or remote training for your team |
| Support | Ticket queue | Dedicated manager, 24/7 UK support team |
| If something breaks | Your problem | We'll look into it |
DIY Setup vs Professional Installation
When we get called in to fix something, it's rarely a genuinely broken system more often it's one that technically works but was never set up right in the first place. Calls end up going to the wrong place, queues were never built, and staff stop trusting it.
How We Install Your London Phone System
1
We'll ask about how your business handles calls day to day, take a look at your broadband, and understand your current setup before suggesting anything. Costs nothing, commits you to nothing.
2
From what we've learned about your business, we put together the actual setup routing, departments, hours, which handsets go where. You'll see the full plan and the price before anything gets ordered.
3
Once the system's installed and configured, we move your existing numbers across. Timing is planned to keep disruption minimal, and your old numbers stay active until we've confirmed the new ones are working properly.
4
We train your team, then you have a named account manager and 24/7 UK support from that point on.
Still tied into a contract elsewhere? We'll work around your notice period rather than around ours. In practice, most switches happen with minimal disruption, since your existing system carries on running until the new one's tested and the numbers have actually moved across.
How to Choose a Business Phone System Provider in London
Questions worth asking any provider
- Where is your support team based, and what hours are they available by phone?
- If we decide to change providers later, can we keep our existing phone numbers?
- What happens to our calls if our internet connection goes down?
- Are installations handled by your own engineers, or do you use third-party contractors?
- Will your system integrate with the software and tools we already use?
- Is the quoted price all-inclusive, or are features such as call recording, mobile apps and Teams integration charged separately?
What to check before you commit
Providers selling business phone systems in London tend to fall into a few broad types, and it's worth knowing which one you're talking to before you commit.
For these firms, telephony is one product among many, so it's often not where their deepest expertise sits.
Whatever they sell is what they'll recommend, simply because it's all they offer. That's not necessarily a problem if it happens to be the right fit for you.
Worth checking the phone number on the page and where the support team actually sits, so you know what "local" really means for that provider.
Phone Systems for London Industries
When a solicitor, accountant or agency misses a call, it's not just inconvenient, it's lost business. Each fee earner gets their own direct line, calls can be recorded where compliance demands it, and everything logs straight into your CRM.
See how we did this for
MLP Law.
Practices that switch typically see fewer missed appointment calls, and reception gets a simpler way to handle the phone without anyone needing to hand out a personal mobile after hours. It plugs straight into the practice management software most UK clinics already run.
See our Dental Tech case study.
As an NHS framework approved supplier, we know what surgeries actually need. The real difference shows at 8am: patients get queue management instead of an engaged tone, callback options instead of holding, and you get reporting that tells you exactly how many calls were answered versus missed.
We integrate with Call Connect GP.
Whichever negotiator picks up, the call gets answered, and it's automatically attached to the right property record without anyone having to log it manually.
See our
Berkley Estates case study.
Reception, offices and every department run off one platform across the whole site, rather than a patchwork of separate lines.
See our
Mountbatten School case study.
Guest room phones, reception and front-of-house all sit on a single system, with nothing bulky to install or maintain on-site.
See our
Athena Hotel case study.
Every location runs on one shared system. Calls between sites cost nothing, staff can transfer to any office as if they were down the hall, and you get a single bill instead of one per building.

PRODUCT
Yeastar Cloud PBX with wireless deployment
The challenge
Athena Hotel is a family-owned boutique hotel in Paddington, one of London's busiest transport and tourism hubs, with more than 25 years of hospitality experience. Its legacy analogue phone system was ageing, expensive to maintain, and out of step with the hotel's boutique standards. Staff had no desktop or mobile apps to manage calls flexibly, and with no Ethernet cabling in most guest rooms, a standard wired IP phone rollout would have meant costly, disruptive building work.
What we installed
A fully managed Yeastar Cloud PBX, with 41 Fanvil H601W wireless IP handsets deployed entirely over Wi-Fi no new cabling required. The wireless handsets were professionally wall-mounted and flush-fitted for a clean finish that suited the hotel's interiors. Two existing business numbers were ported across with zero downtime, and four SIP trunks were provisioned so the hotel has room to grow.
The results
- 41 Fanvil H601W wireless IP handsets installed with no new Ethernet infrastructure
- 100% wireless deployment across every guest room
- Zero-downtime number porting for both business lines
- Scalable SIP connectivity as the business grows
"Switching to The VoIP Shop has made a real difference to how we run the hotel day to day. The old phone system was holding us back, and the new handsets look fantastic in every room. The whole process was smooth from start to finish, and it's reassuring to know the system can grow with us as the business does."

London Business Phone System FAQs
Do you have engineers based in London, or is this a call centre?
Our support team is UK-based and available 24/7, with a named account manager and engineers available for London site visits when required.
Will we keep our 020 number when we switch?
Yes. Number porting moves it across with minimal disruption, and it's portable again if you ever leave.
Is broadband in London good enough for VoIP, and what happens if it drops?
Full-fibre availability varies by postcode, so we check your specific premises during your free consultation. Where configured, calls can fail over automatically to mobiles or another site if your internet drops, and Gold Level support adds 5G backup.
How long does installation take?
Most systems are installed within a few days of your free consultation. Numbers port alongside the setup, and existing phones stay live until the new system is confirmed working, so disruption is kept to a minimum.
Which London businesses do you work with?
Businesses like Athena Hotel in Paddington, where we deployed a 41-handset wireless cloud PBX with zero downtime. We're also NHS framework approved, working with GP surgeries and healthcare providers.
How do you compare to other London providers?
We're not tied to one platform, we publish our pricing upfront, and we're NHS framework approved.
