Best Cordless Phones for the Office

The UK business cordless phone market has changed dramatically since the PSTN switch-off began. Analogue DECT phones that plug into a BT wall socket are being phased out – if your office cordless phones connect to a traditional landline, they will stop working by January 2027. The replacement: IP-DECT phones that connect to your internet router and work with cloud phone systems like RingCentral, Vonage, and Dialpad.

We’ve researched the current UK market to find the best cordless office phones available in 2026 – all VoIP-native, all PSTN-proof, and all available from UK suppliers. Whether you need a single handset for reception or a multi-cell system covering an entire warehouse, this guide covers your options.

Best Office Cordless Phones at a Glance

The Yealink W73P (£78 bundle) is the best value cordless office phone for most UK businesses. For rugged environments, the Yealink W57R (£122) leads on durability and battery life.

The PSTN Switch-Off: Why Your Current Phones May Stop Working

BT is permanently switching off the UK’s traditional landline network (PSTN) by January 2027. Any cordless phone connected to a BT wall socket will stop working – you need VoIP-native IP-DECT phones instead.

The PSTN switch-off affects every business still using traditional phone lines. Here’s what it means for cordless phones specifically:

If you’re buying a new cordless phone system in 2026, only buy IP-DECT. Every phone recommended in this guide runs over your internet connection – none depend on the PSTN.

Keeping old phones temporarily: An ATA (Analogue Telephone Adapter) like the Grandstream HT802 (~£30) can connect an old analogue DECT base to your internet. This is a stopgap – not a long-term solution. The ATA dies with your internet, and you lose features like caller ID display and call transfer that IP-DECT handles natively.

Best VoIP Cordless Phones for UK Offices in 2026

All phones below are VoIP-native (SIP), work with any cloud phone system (RingCentral, Vonage, 8×8, 3CX, Zoom Phone), and are available from UK suppliers. Every price excludes VAT.

Yealink W73P – Best Value for General Office Use

The Yealink W73P is a bundle: the W73H handset plus the W70B base station for around £78 from UK suppliers. It’s the default recommendation for small UK offices migrating from analogue cordless phones. The W70B base supports up to 10 handsets and 10 SIP accounts – enough for most small businesses.

Price: ~£78 (W73P bundle) | Additional W73H handsets: ~£45 each
Range: 50m indoors / 300m outdoors
Upgrade path: For Bluetooth headset support, step up to the Yealink W74H (~£75-85) or W78H (~£68-82).

Yealink W57R – Best for Warehouses and Workshops

If your team works in environments where phones get dropped, splashed, or covered in dust, the W57R is built for it. IP54-rated (dust and water spray protection), tested to survive 3.5-metre drops onto concrete, and with the longest battery life of any business DECT handset we’ve seen: 40 hours talk time, 575 hours standby.

Price: ~£122 (handset only) + W70B base ~£44
Range: 50m indoors / 300m outdoors
Also consider: The Yealink W59R (~£98) if you need full IP67 waterproofing and Bluetooth – it’s cheaper but has shorter battery life (28h talk).

Grandstream DP752 + DP730 – Best Budget System

For businesses that need the cheapest possible VoIP cordless phone that actually works reliably, the Grandstream combination is hard to beat. The DP752 base (£58) plus DP730 handset (£65-75) gives you a complete system for around £120 – and the DP730 has excellent battery life (40h talk, 500h standby).

Price: ~£120 (base + handset) | Additional DP730 handsets: ~£65-75 each

Gigaset S700H PRO – Best Premium Office Handset

The Gigaset S700H PRO is the most feature-rich office DECT handset at a reasonable price. Bluetooth 4.2 means you can pair wireless headsets directly, 12 programmable function keys give quick access to speed dials and features, and the 2.4-inch colour TFT display is sharper than anything in the Yealink range at this price.

Requires a Gigaset N670 IP PRO base (~£100) or N870 IP PRO for multi-cell deployments. The N670 is popular with UK resellers for small-to-medium offices.

Price: ~£76 (handset) + N670 base ~£100
Range: 50m indoors / 300m outdoors (standard DECT)

Snom M90 – Best for Healthcare and Clinical Environments

The Snom M90 is purpose-built for healthcare. Its antibacterial housing (tested to JIS-Z801) actively inhibits bacterial growth – a genuine requirement in clinical settings, not just marketing. IP65 rated for dust and water protection, with Bluetooth, HD voice, and a panic/alarm button.

At £315+, it’s expensive – but in NHS or private healthcare environments where infection control and durability matter, it’s the specialist choice. The Snom M400 base (£110-150) or M900 enterprise manager supports it.

Price: ~£315-470 (handset, depending on supplier) + M400 base ~£110-150
Also consider: The Snom M85 (~£320-452) for warehouse and industrial use without the antibacterial housing.

Poly Rove 30 – Best Enterprise Option

The Poly Rove 30 is the premium enterprise choice. IP65 ruggedised, Microban antimicrobial coating, 2m drop rating, and designed for high-density enterprise deployments. The Rove B4 base supports 30 handsets and multi-cell roaming across floors.

At £166 per handset (with the B4 base at ~£495), this is a significant investment. It’s best suited to organisations with 20+ mobile workers who need a polished, enterprise-grade cordless system – especially in healthcare, hospitality, or food service where antimicrobial protection is valued.

Price: ~£166 (handset) + Rove B4 base ~£495

Multi-Cell Systems for Larger Offices

For offices, warehouses, or campuses with 20-250+ users, multi-cell IP-DECT systems create seamless roaming coverage across floors and buildings – handsets switch between base stations automatically as you walk.

All multi-cell systems support seamless handover – when a user walks from one base station’s range into another, the call transfers automatically without dropping. This is essential for warehouses, hospitals, and multi-floor offices.

Do You Still Need Cordless Phones? DECT vs Bluetooth Headsets

For desk-based office workers, Bluetooth headsets paired with softphones (Teams, Zoom, RingCentral app) are replacing DECT handsets. For warehouse, retail, healthcare, and reception staff, DECT cordless phones remain the better choice.

The honest question in 2026: does your team actually need physical cordless handsets?

Choose DECT cordless phones if:

• Staff are mobile within a building (warehouse, hospital, shop floor, reception) and need 50-300m range
• Your environment has high RF interference that degrades Bluetooth (10-30m range)
• You need dedicated phone devices – not everyone can carry a laptop or smartphone on shift
• Staff need instant pickup and speakerphone without logging into software

Choose Bluetooth headsets + softphones if:

• Staff work at desks with laptops running RingCentral, Dialpad, or Microsoft Teams
• Your team is hybrid/remote and needs to take calls from home and office
• You want to eliminate hardware costs – softphones run on devices staff already own
• 10-30m Bluetooth range is sufficient for your office layout

Many businesses use both: softphones for desk staff, DECT handsets for reception, warehouse, and on-site teams. For a full comparison of cloud phone systems that power either setup, see our guide to the best UK VoIP providers and best telephone systems for small businesses.

How to Choose the Right Cordless Phone

Choose based on three factors: your environment (office, warehouse, clinical), the number of handsets you need (single-cell for up to 10, multi-cell for 20+), and your VoIP provider’s compatibility list.

Before buying, check three things:

1. VoIP provider compatibility – confirm your cloud phone provider (RingCentral, Vonage, bOnline, etc.) supports the handset model. Most SIP phones work universally, but certified models get auto-provisioning
2. Number of handsets needed now + in 12 months – single-cell bases (W70B, DP752) support up to 5-10 handsets. If you might need more, invest in a multi-cell base from the start
3. Your internet connection – each simultaneous call uses ~100kbps. With 10 handsets active at once, you need at least 1Mbps upload dedicated to voice. Most business broadband handles this easily

Our Verdict

The Yealink W73P bundle (~£78) is the best cordless office phone for most UK businesses – affordable, reliable, future-proof, and compatible with every major VoIP platform.

If you’re replacing old analogue cordless phones before the PSTN switch-off, the Yealink W73P is the straightforward choice. At ~£78 for a complete handset-plus-base bundle, it’s cheaper than most of the discontinued phones in our old list – and it works with any SIP-compatible cloud phone system. The 35-hour battery life and 10-handset capacity mean most small offices won’t outgrow it.

For specialist environments, the Yealink W57R (warehouses), Snom M90 (healthcare), and Poly Rove 30 (enterprise antimicrobial) serve their niches well – but at higher price points that are justified by the specific protection ratings and features those environments demand.

The broader question is whether your office needs cordless handsets at all. If your team works at desks with laptops, a Bluetooth headset paired with RingCentral, Dialpad, or Microsoft Teams may be all you need – no handsets, no base stations,

no hardware to manage. DECT cordless phones remain essential for reception desks, warehouses, shop floors, and any environment where staff need a dedicated phone they can carry across a building.
