As a business leader, you know that a competitive employee benefits package is vital for attracting and retaining top talent. Private Medical Insurance (PMI) is a cornerstone of this, but what happens when your renewal premium soars, or the service from your current provider falters? At WeCovr, with our experience in arranging over 900,000 policies of various kinds, we know the dilemma: you want a better deal, but you can't risk leaving employees with existing health conditions unprotected.
This is where understanding how to switch your UK private medical insurance on a Medical History Disregarded (MHD) basis is not just helpful—it's critical. This guide will walk you through the entire process, ensuring you can transfer your company's healthcare scheme without jeopardising the cover for your most valued asset: your people.
How to transfer corporate healthcare without losing cover for sick staff
The single most effective way to transfer your company's health insurance without losing cover for employees currently receiving treatment or with pre-existing conditions is to switch to a new provider using Medical History Disregarded (MHD) underwriting.
This special transfer term compels the new insurer to accept all of your employees and their existing medical conditions, provided they were covered under your previous policy. It effectively creates a seamless bridge of cover, ensuring no one is left worse off.
However, it's crucial to understand that this is not a standard offering for all businesses. It's a complex process typically reserved for larger SME and corporate schemes, and navigating it successfully almost always requires the expertise of a specialist PMI broker.
The Golden Rule of UK Private Health Insurance
Before we dive deeper, it's essential to grasp a fundamental principle of the UK PMI market. Standard private health cover is designed for acute conditions—illnesses or injuries that are short-term and likely to respond quickly to treatment.
Private medical insurance in the UK does not cover chronic conditions (long-term illnesses like diabetes, asthma, or hypertension that require ongoing management rather than a cure). It also typically excludes pre-existing conditions that occurred before the policy began, unless specific underwriting terms like MHD are in place.
What is Medical History Disregarded (MHD) Underwriting?
Medical History Disregarded underwriting is exactly what its name implies. When a policy is set up on an MHD basis, the insurer agrees to disregard the past medical history of all members joining the scheme.
This means that any pre-existing conditions an employee has will be covered, as long as they fall within the policy's general terms and are not for a chronic condition requiring long-term management. This is the most comprehensive type of underwriting available and provides the highest level of certainty for your team.
For a switch, it means the new insurer commits to a "no worse off" position, continuing cover for conditions that the previous insurer was already covering.
How MHD Compares to Other Underwriting Types
To appreciate the value of MHD, it helps to see how it stacks up against the other main types of underwriting used for smaller groups.
| Underwriting Type | How it Works | Best For |
|---|---|---|
| Medical History Disregarded (MHD) | Insurer ignores all pre-existing conditions. Most comprehensive cover. | Larger SMEs and corporate groups (typically 20+ employees) switching providers. |
| Full Medical Underwriting (FMU) | Each employee completes a detailed health questionnaire. Insurer assesses risk and may apply specific exclusions. | Small groups or individuals who are healthy and want certainty of cover from day one. |
| Moratorium (MORI) | No medical questions upfront. Pre-existing conditions from the last 5 years are excluded for a set period (usually 24 months). | Small businesses that want a quick, simple setup and have a young, healthy workforce. |
As you can see, trying to switch a company scheme with employees undergoing treatment on a Moratorium or FMU basis would be disastrous. The new insurer would simply exclude their ongoing conditions, potentially leaving them with a huge financial and emotional burden.
The Critical Importance of Protecting Your Team's Health Cover
Let's consider a practical scenario.
Your company, "Innovate Ltd," has a 30-person health scheme with Insurer A. Your renewal premium has just increased by 25%. One of your senior engineers, David, was diagnosed with a treatable form of lymphoma six months ago and is halfway through a course of chemotherapy, fully funded by your current PMI policy.
You find a much cheaper quote online from Insurer B and decide to switch. However, you don't use a broker and simply sign up for their standard Moratorium policy.
The consequence? Insurer B will not cover David's ongoing cancer treatment. It's a pre-existing condition, and he has received advice and treatment for it in the last five years. Your company has inadvertently removed a life-changing benefit from a key employee at the worst possible time, damaging morale and trust, and potentially opening your business to legal challenges.
An MHD switch would have prevented this entirely. A broker would ensure Insurer B agreed to continue covering David's treatment seamlessly.
Why Would an SME Switch Health Insurance Providers?
Rising costs are the number one driver, but they are far from the only reason a savvy business might look to review the market.
- Significant Premium Increases: Annual premium hikes of 15-30% are not uncommon, driven by medical inflation, the group's age profile, and their claims history.
- Poor Service Levels: Frustration with slow claims processing, unhelpful call centres, or a difficult pre-authorisation process can make a switch worthwhile even if the cost is similar.
- Benefit Enhancements: The PMI market is constantly evolving. You may want to switch to a provider offering better mental health support, virtual GP services, or advanced cancer cover.
- Desire for a New Hospital Network: Your current policy might have a limited hospital list that excludes a facility your employees prefer or need to access.
- Adding Value: Some modern insurers, like Vitality, build their proposition around wellness programmes and rewards, which can be a powerful tool for employee engagement.
The MHD Switching Process: A Step-by-Step Guide
Switching a corporate scheme on an MHD basis is a structured process. While a broker like WeCovr will handle the heavy lifting, understanding the steps helps you prepare and manage the project internally.
Step 1: Internal Review & Decision
Before approaching the market, review your current policy. What do you like? What's missing? What is your budget? This clarity is crucial for defining your objectives for the switch.
Step 2: Appoint a Specialist Broker
This is the most important step. An independent broker does not charge you for their service (they are paid a commission by the insurer you choose). Their role is to:
- Understand your unique needs.
- Gather the required data for quoting.
- Access the specialist corporate teams within each insurance company.
- Negotiate terms and pricing on your behalf.
- Present you with a clear, like-for-like comparison.
Step 3: Gather Your Data
Your broker will need the following to get accurate MHD transfer quotes:
- A full list of members to be covered (including dates of birth).
- A copy of your current policy certificate or benefit summary.
- Your claims history for the past 3 years.
- Your renewal terms from your current insurer.
Step 4: The Market Review
Your broker will take your data to a panel of suitable UK insurers (such as Aviva, AXA Health, Bupa, and Vitality). They will request quotes on an MHD transfer basis, ensuring each insurer agrees to continue cover for all existing conditions.
Step 5: Analyse the Quotations
Your broker will present the results in an easy-to-understand report. This shouldn't just be about the headline price. It will compare:
- Core benefits and any key differences.
- Outpatient limits and excess levels.
- Mental health and cancer cover pathways.
- Value-added benefits (Virtual GPs, wellness apps, etc.).
- Insurer service ratings and claims philosophy.
Step 6: Finalise and Implement the Switch
Once you've chosen your new provider, your broker will manage all the paperwork. They will ensure the new policy starts the exact day the old one ends, guaranteeing no break in cover. They will also provide documentation to help you communicate the (positive) change to your employees.
Key Insurer Criteria for an MHD Transfer
Insurers don't offer MHD terms to everyone. They are taking on a significant unknown risk by not asking for medical history, so they have strict criteria.
- Group Size: This is paramount. Most insurers require a minimum of 15-20 employees to consider an MHD switch. For very small groups, it's generally not an option.
- Claims History (Loss Ratio): The insurer will analyse your claims data. Your "loss ratio" is the value of your claims divided by the premium you paid. If your group has consistently claimed far more than it pays in premium, other insurers may decline to quote or offer very high prices.
- Continuity of Cover: You must be switching from an existing group PMI scheme. MHD is not available for a brand-new scheme.
- Comparable Underwriting: Your existing scheme must have been on a comparable basis, usually MHD or in some cases, a long-standing FMU scheme.
- Industry: Insurers may be wary of certain high-risk industries (e.g., heavy manual labour, professional sports).
Common Mistakes to Avoid When Switching Your SME Policy
Navigating an MHD switch is a minefield for the inexperienced. Here are the most common pitfalls we see businesses fall into.
- Going Direct to an Insurer: While an insurer can sell you their own policy, they cannot provide independent advice or compare the whole market for you. This violates a core principle of finding the best solution, not just one solution.
- Focusing Only on Price: The cheapest quote is often cheap for a reason. It might have a £500 outpatient limit, exclude key psychiatric cover, or use a very restricted hospital list. Value is the goal, not just cost.
- Misunderstanding Benefit Variations: Even on an MHD switch, benefit limits can change. Your old policy might have unlimited outpatient diagnostics, but the new one may cap it at £1,000. It's vital to understand these differences.
- Allowing a Gap in Cover: Letting your old policy lapse on the 31st and the new one start on the 2nd is a huge risk. If an employee has a heart attack on the 1st, they are uninsured. A broker ensures a seamless, back-to-back transition.
- Poor Communication with Staff: Switching benefits can make employees nervous. Clear, positive communication is key. Frame it as an enhancement or a move to a better service partner, highlighting the continuity of their personal cover.
