TL;DR: Travel insurance on dialysis is possible but represents one of the most complex pre-existing condition cases in travel underwriting. Haemodialysis patients must arrange dialysis sessions at a facility abroad before departure - this is a logistical requirement independent of insurance. Peritoneal dialysis patients have more flexibility. Specialist brokers and renal-specific travel agencies handle both the insurance and the dialysis booking. Costs are high and planning lead time is substantial.
KEY FACTS

What to declare on travel insurance when on dialysis
Dialysis patients must declare the dialysis itself, the underlying cause of kidney failure - most commonly diabetic nephropathy, hypertension-related renal failure, polycystic kidney disease, glomerulonephritis, or other causes - and all associated conditions and medications. The declaration should specify whether you are on haemodialysis or peritoneal dialysis, the frequency and duration of sessions, and how long you have been dialysis-dependent. All related conditions such as anaemia, hypertension, cardiovascular disease, diabetes, and peripheral vascular disease must be declared as separate pre-existing conditions - dialysis-dependent patients frequently have multiple co-morbidities that are each independently material to underwriting. If you are on the transplant waiting list, this should also be disclosed. The Consumer Insurance (Disclosure and Representations) Act 2012 requires consumers to take reasonable care to accurately represent their medical situation, and dialysis is among the highest-complexity cases in travel insurance underwriting.
How insurers assess dialysis patients
Dialysis represents end-stage renal disease (ESRD) and is assessed as a high-complexity pre-existing condition by all travel insurers. Standard insurers will not underwrite dialysis patients - specialist brokers with specific renal underwriting capability are required. Even among specialist brokers, not all will cover all dialysis patients - those with significant cardiovascular co-morbidities, recent cardiac events, or other complex concurrent conditions face the most restrictive underwriting environment. Premiums for dialysis travel insurance are substantially higher than standard pre-existing condition policies, reflecting the genuine clinical complexity and the high potential cost of emergency renal care abroad. MoneyHelper's directory (moneyhelper.org.uk/en/everyday-money/insurance/travel-insurance-directory) is the primary publicly funded signposting resource. Kidney Care UK and the British Kidney Patient Association also provide signposting to specialist renal travel insurers and renal holiday companies who have established relationships with dialysis units internationally.
Arranging haemodialysis abroad - the logistics
Haemodialysis patients cannot travel without pre-booking dialysis sessions at a registered facility at their destination - this is a non-negotiable clinical requirement entirely separate from travel insurance. The process involves contacting your own renal unit, who can assist in identifying partner facilities abroad and providing the clinical documentation required by overseas units. This documentation typically includes your latest blood results, your dialysis prescription, your medical history, and details of your current access (arteriovenous fistula, graft, or catheter). Lead time for booking dialysis abroad varies by destination - popular European holiday destinations such as Spain, Greece, and Portugal have established dialysis tourism infrastructure and bookings may be arranged weeks in advance. More remote or less common destinations may require months of lead time and may not have available capacity. Kidney Care UK's guidance and the BKPA both signpost to specialist renal holiday agencies who manage this process on behalf of patients (kidneycareuk.org). Costs for dialysis sessions abroad are significant and are typically not covered by the GHIC for ongoing treatment - only emergency sessions would be covered under GHIC terms.
Peritoneal dialysis and travel flexibility
Patients on continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysis (APD) have considerably more travel flexibility than haemodialysis patients, as PD exchanges can be performed independently at the destination without booking sessions at a dialysis unit. The primary logistical challenge is supply - PD fluid bags and associated equipment are bulky and heavy, and most airlines will not transport sufficient supplies in checked luggage for extended trips. Kidney Care UK advises that PD fluid can often be arranged for delivery directly to the destination - your renal unit and your PD supplies manufacturer can assist in coordinating international delivery. For APD patients, the cycler machine required for overnight automated exchanges must travel with you - confirm airline regulations for medical equipment in advance and carry documentation confirming the medical necessity of the equipment. Research storage requirements for PD fluid at your destination, including temperature constraints.
What a dialysis travel insurance policy should cover
A specialist policy for a dialysis patient should cover emergency medical treatment abroad arising from renal or dialysis-related complications, including access failure, peritonitis for PD patients, or haemodynamic complications during or between haemodialysis sessions. It should cover medical repatriation if a complication requires return to the UK under clinical supervision. It should also cover trip cancellation if your condition deteriorates before departure to the point where your nephrologist advises against travel. Confirm whether the policy covers the cost of dialysis sessions abroad - most travel insurance policies do not cover the routine cost of pre-booked dialysis sessions, treating these as planned treatment rather than emergency medical expenses. The distinction between emergency dialysis cover and routine session costs is a critical policy detail to clarify before purchase. Also confirm whether co-morbidities such as diabetes or cardiovascular disease are covered within the same policy.

Frequently Asked Questions
Can dialysis patients travel abroad at all?
Yes. Haemodialysis patients can travel provided dialysis sessions are pre-booked at a registered facility at the destination before departure. Peritoneal dialysis patients have greater flexibility as exchanges can often be self-managed at the destination with appropriate supply logistics. Both Kidney Care UK and the British Kidney Patient Association provide practical guidance and signposting to specialist renal travel agencies.
Does travel insurance cover the cost of dialysis sessions abroad?
Most travel insurance policies, including specialist pre-existing condition policies, do not cover the routine cost of pre-booked dialysis sessions abroad, treating them as planned ongoing treatment rather than emergency medical expenses. Emergency dialysis required due to an unexpected complication is more likely to be covered. Clarify this distinction explicitly with any insurer before purchasing.
Does the GHIC cover dialysis treatment in Europe?
The GHIC entitles UK residents to access state medical treatment in EU countries at the same cost as local residents. Emergency dialysis in a state facility would in principle be accessible under GHIC, but the GHIC does not cover planned ongoing dialysis sessions as a substitute for your regular treatment schedule. The NHS Business Services Authority confirms the GHIC is not a substitute for travel insurance (nhsbsa.nhs.uk).
How far in advance do I need to book dialysis abroad?
Lead time varies significantly by destination. Popular European dialysis tourism destinations such as Spain, Portugal, and Greece can often accommodate bookings several weeks in advance. Less common destinations may require months of preparation or may not have capacity available. Your renal unit can advise and assist with the booking process and the clinical documentation required by overseas facilities.
Where can I find travel insurance that covers dialysis patients?
MoneyHelper's travel insurance directory is the primary publicly funded resource. Kidney Care UK (kidneycareuk.org) and the British Kidney Patient Association (britishkidney-pa.co.uk) also signpost to specialist renal travel insurers and renal holiday companies with established dialysis booking networks. Standard comparison websites will not surface appropriate specialist underwriters for dialysis patients.
