How underwriting usually handles it

• Health insurers usually exclude cardiovascular investigation and treatment where blood pressure is already being treated.
• Life and critical illness underwriters ask for recent readings and may apply a loading rather than declining.
• Good control over a period of time generally improves the terms offered.
• A moratorium policy treats it as pre-existing while medication or monitoring continues.

Which underwriting basis you choose changes the answer more than the condition itself does. Our guide to moratorium versus full medical underwriting explains the two routes; in short, a moratorium asks nothing up front and decides later, while full underwriting decides now and puts the answer in writing.

What is commonly excluded or limited

• Cardiovascular exclusions often extend well beyond blood pressure, catching the heart and circulation generally.
• Ongoing medication and monitoring sit outside health insurance in any case.
• Complications attributed to hypertension are usually caught by the same exclusion.

Nothing here is universal. Two insurers can take different views of the same history, and the same insurer can take different views on two products. The policy wording is the only thing that decides it.

What happens when you claim

• A heart-related claim will be assessed against the exclusion and the medical record.
• Critical illness claims turn on the specific definition in the policy, not on a general term like "heart problem".
• Emergency care is an NHS matter.

Insurers must handle claims promptly and fairly and must not turn a claim down unreasonably; the rules are in the FCA’s insurance conduct sourcebook. ^[1] If you think a decision is wrong, you can complain and then take it to the Financial Ombudsman Service free of charge. ^[2] Our complaints page sets out both routes.

The NHS route

Whatever an insurer decides, NHS care is unaffected: buying or being refused insurance changes nothing about your entitlement. Treatment on the NHS follows clinical guidance rather than policy wording. ^{[5] [4]} For information and support about the condition itself, the British Heart Foundation is a better place than an insurance site.

Questions to ask before you buy

1. How wide is the cardiovascular exclusion — blood pressure only, or the heart and circulation?
2. On a moratorium policy, exactly how far back does the look-back go, and how long must I be clear?
3. If I choose full underwriting instead, will you put the exclusion wording in writing before I pay?
4. Would the exclusion be reviewed later, and on what evidence?
5. Does the exclusion extend to related conditions and complications, or only to this one?

An adviser can answer those questions for your own history; we cannot, and we do not try to. Anyone advising you on insurance must be authorised, and you can check them on the Financial Services Register. ^[3] Free impartial guidance is also available from MoneyHelper. ^[6]
