Preparing your business for the WLR switch-off and ensuring a smooth transition

Most businesses currently rely on traditional analogue lines, ISDN, or broadband connected through Wholesale Line Rental (WLR) – the infrastructure powering your calls, data, security systems, and more. But the truth is, the WLR switch-off is on the horizon – and it’s affecting businesses in ways they might not be expecting. It’s not just about telephony! Do you really know what your WLR lines are powering? And what your options are?

The countdown is on - Openreach’s deadline to shut down traditional analogue phone lines, ISDN, broadband, and other vital WLR-connected services is January 2027 (or even sooner). If you’re not fully prepared, your business could face serious disruption:

Your phones may stop ringing, cutting off essential customer contact

Lifts and critical facilities could cease functioning

Broadband and internet services might go offline unexpectedly

Your customers’ access to your services could be lost

What exactly are your WLR lines powering?

Many businesses don’t realise just how much relies on their existing WLR lines and traditional networks. The PSTN and WLR include more than just voice calls; they power card payment terminals, security alarms, lift controls, entry systems, CCTV, emergency systems, and many other critical business operations.

Without a clear understanding of which lines are used for what, you risk missing vital services during the switch-over. Managing large estates or multiple sites makes this even trickier – you may be unaware of what lines you have, what they’re used for, where they’re located, or what they are connected to, creating a significant business risk.

What do you do when landlines go digital?

Don’t wait until disruption strikes. The earlier you identify your current setup and plan your migration, the smoother and more secure your transition will be.

The NHS leader’s CAF & DSPT checklist: cyber resilience, compliance, and assurance in 2026

For NHS Trust leaders, meeting the demands of cyber security assurance has never been more urgent. With the Data Security and Protection Toolkit (DSPT) now aligned to the Cyber Assessment Framework (CAF), NHS organisations now need to demonstrate not only whether controls are in place, but how effective they are in practice.

Why financial services firms need advanced connectivity & security in 2026

The UK financial services sector entered 2026 as one of the most digitally advanced industries in the world. Mobile banking dominates customer interactions, neobanks (a bank that only operates online and has no network of physical locations) continue to disrupt traditional models, and AI is rapidly expanding across fraud prevention, analytics, and customer experience. But with rapid digital acceleration comes increased cyber risk, regulatory pressure, and infrastructure demands. Financial institutions now require advanced connectivity and robust security to stay operational, competitive, and compliant.

Understanding Windows 10 Extended Security Updates (ESU) - what your business needs to know in 2026

As of 14 October 2025, Microsoft officially ended free security updates for Windows 10. Organisations that continue operating Windows 10 devices today - in 2026 - are now doing so in a post‑support environment, relying either on paid Extended Security Updates (ESU) or accepting increasing cyber risk. Windows updates are the backbone of endpoint security, identifying new vulnerabilities and closing them before attackers exploit them. Since the end of support deadline passed, unpatched vulnerabilities accumulate quickly, creating growing exposure across any estate still running Windows 10. Continuing with Windows 10 in 2026 can lead to: Higher cyber‑attack risk, particularly ransomware Compliance issues (Cyber Essentials, ISO 27001, GDPR, FCA/financial sector requirements) Reduced software compatibility with modern applications and security tools Increased helpdesk overhead due to outdated hardware and OS issues For organisations, this is no longer preparation for a future deadline - it’s about reducing risk now and completing the transition to a modern, supported operating system. Your organisation’s options in 2026 Businesses now have three strategic pathways depending on their hardware, budget cycle, and deployment readiness. 1. Upgrade existing compatible devices to Windows 11 If your current hardware meets Microsoft’s requirements, upgrading remains the fastest and most cost‑effective way to move away from Windows 10 ESU dependency. Benefits include: Ongoing security updates Modern protection (TPM 2.0, enhanced kernel security, improved identity protection) Support for AI‑powered features and future Microsoft roadmaps Lower risk and long‑term stability If your business has Windows 10 machines still capable of upgrading, this should be the first route explored. 2. Refresh your estate with Windows 11‑ready devices Many Windows 10 machines still in use in 2026 are now five to eight years old, and often: Fall below modern security standards Cause productivity bottlenecks Increase support tickets Consume disproportionate IT resources A structured hardware refresh offers: Predictable lifecycle management Improved reliability and performance Standardisation across departments Compatibility with modern security and MDM tooling Wavenet supports staged refresh programmes aligned with fiscal planning, ensuring minimal business disruption. 3. Continue using Windows 10 with Extended Security Updates (ESU) Microsoft’s Windows 10 ESU programme is still available, but it is: Paid per device, per year Increasing in cost each year (designed to encourage migration) Security‑only - no features or performance improvements A temporary safety net, not a long‑term strategy ESU is most appropriate when: Line‑of‑business applications are not yet Windows 11 certified You need additional time for a phased rollout Budget cycles are delaying upgrades or refresh Remote / operational environments require longer transition periods Most organisations still using ESU in 2026 should plan to exit it within the next 12–24 months. Assessing your Windows 11 readiness in 2026 At this stage, businesses need more than a simple device‑level compatibility check. A comprehensive analysis includes: Hardware readiness across the estate Application and vendor compatibility Driver and firmware validation Intune / MDM alignment Security baselines and policy impacts User profile and data considerations Deployment sequencing and pilot planning Wavenet offers full readiness assessments to provide a clear view of which devices can be upgraded, which require replacement, and where ESU may remain temporarily necessary. Why 2026 is a critical year for migration With the end of support now behind us, delaying migration further increases: Security exposure Operational risk Compliance penalties ESU costs End‑user frustration from aging hardware A well‑structured migration programme delivers: A secure, modernised endpoint environment Lower long‑term support cost Improved employee experience Better alignment with Microsoft’s cloud and security roadmap Many organisations are now accelerating migration to remove the remaining Windows 10 footprint entirely. How Wavenet supports your Windows 11 journey Wavenet provides end‑to‑end Windows 11 migration services, including: Estate discovery & readiness assessment Hardware lifecycle planning and procurement Application compatibility testing Managed upgrade or Autopilot deployment Configuration, security baselines, and Intune alignment ESU planning (where absolutely necessary) Phased rollouts with minimal disruption Whether you’re upgrading compatible devices, refreshing your estate, or transitioning off ESU entirely, Wavenet ensures a smooth, secure, and controlled migration.
