Home insurance is designed to protect your home and belongings against events like fire, storm damage and theft. It becomes especially important when you are buying with a mortgage. When considering home insurance for mortgage arrangements, lenders want to know the property can be repaired or rebuilt if
something serious happens.
For buyers, understanding how home insurance for mortgage applications works can help streamline approval and avoid delays at exchange.
Summary
For most UK mortgages, lenders require buildings insurance (usually from exchange of contracts) that covers at least the property’s rebuild cost to protect their security in the home. Contents insurance, which covers your belongings, is usually optional but often sensible once you move in. Home insurance is not a legal requirement, but buildings cover is effectively mandatory where a mortgage is involved, because it protects both lender and homeowner. Many buyers ask, “Is house insurance compulsory?” or “Do I need home insurance?”: While not a legal requirement, lenders usually require it in practice for mortgaged purchases.
Life and critical illness cover are not compulsory, but can add valuable protection for your family and mortgage payments if something serious happens. If you are asking “do you need home insurance for a mortgage?”, the practical answer is yes for buildings insurance; contents and wider protection depend on your circumstances, risk tolerance and budget. If you are also asking “what insurance do I need for a mortgage?”, arrange cover early and tailor it to your lender’s requirements, your property’s risks, and your own situation.

The scope of home insurance cover
Most home insurance policies fall into two main parts:
- Buildings insurance — covers the structure of your home (walls, roof, floors, fitted kitchen, bathroom, built-in wardrobes and similar fixtures) against insured events such as fire, storm, flood (depending on the policy), escape of water, subsidence and vandalism.
- Contents insurance — covers your personal belongings, such as furniture, electronics, clothing and many household items, if they are stolen, damaged or destroyed by an insured event.
Some policies combine buildings and contents into a single “home insurance” policy, while others let you buy each part separately. Understanding these components helps ensure you are not underinsured on the building or overlooking your contents cover.
Why home insurance is a priority for homeowners
Buildings insurance is not only a common lender condition, it is also a practical safeguard for homeowners. Without it, the full cost of repairing or rebuilding after a major event — such as a fire or serious storm damage — would fall on you.
By arranging suitable buildings cover (sometimes called building insurance for mortgage purposes) and, where appropriate, contents cover, you protect both your property and your wider financial position if something unexpected happens. This is particularly relevant when arranging home insurance for mortgage approval, because your lender will check that appropriate cover is in place.
Do you need home insurance for a mortgage?
In most cases, yes — you will need buildings insurance in place to secure and complete on a residential mortgage. Lenders want to see that, if a major insured event occurs, there is a policy in place to pay for repair or reconstruction up to the rebuild cost stated in your valuation or survey.
Although there is no law that forces homeowners to buy building insurance, mortgage lenders almost always make it a condition of the mortgage offer. Without proof of adequate building cover from the exchange, they may not permit completion.
Understanding lender requirements for buildings insurance
For building insurance for mortgage applications, most lenders will:
- Expect buildings insurance to start from the exchange of contracts, when you become legally responsible for the property.
- Require the sum insured to be at least equal to the estimated rebuild cost of the property, not just the purchase price.
- Prefer to be noted as an interested party on the policy to recognise their interest in the property.
If these conditions are not met, lenders may delay or refuse to release funds. This is why it is important to factor building insurance into your home-buying checklist alongside your mortgage offer, solicitor and surveys.

Buildings insurance for a mortgage
What does building insurance cover?
Buildings insurance typically covers the cost of repairing or rebuilding your home if it is damaged by insured events such as:
- Fire or explosion.
- Storm or, in some areas, flood (subject to policy terms).
- Escaping water from pipes or tanks.
- Subsidence, heave or landslip (if included).
- Vandalism or impact damage.
It usually includes the main structure plus permanent fixtures like fitted kitchens and bathrooms, and may cover outbuildings, garages, driveways or boundary walls, depending on the policy. Checking the schedule and policy wording is essential to understanding the exact scope of cover.
Why building insurance is effectively mandatory with a mortgage
Lenders rely on the value of your property as security for the loan. If a serious incident were to destroy or severely damage the home and there was no insurance, both you and the lender could face a substantial financial loss.
By requiring buildings insurance that covers the full rebuild cost, lenders reduce this risk and ensure that funds are available to repair or rebuild following a major insured event. For you as the homeowner, it also means you are not left to fund a rebuild yourself.
Choosing the right building insurance policy
When comparing policies, consider:
- The sum insured – does it cover the full rebuild cost, including professional fees and site clearance?
- Excesses – different excesses may apply for escape of water, subsidence or other perils.
- Area-specific risks, such as flood or subsidence, and whether they are included or excluded.
- Options like accidental damage or legal expenses cover, if relevant.
Your lender may suggest a particular insurer, but you are generally free to shop around as long as your chosen policy meets their minimum requirements.
Life assurance, critical illness and your mortgage
Life assurance and critical illness cover are not normally compulsory for a mortgage in the UK, but they can play an important role in protecting your home and family.
- Life insurance can provide a lump sum to clear or reduce the mortgage if you die during the policy term, helping your dependents remain in the property.
- Critical illness cover pays out if you are diagnosed with a specified serious illness, which can help you pay off or reduce the mortgage or cover payments during treatment and recovery.
People often ask variants such as “do you need life insurance to get a mortgage?”, “do you need life insurance to buy a house?”, “do you need life insurance for a mortgage?”, “is life insurance compulsory for mortgage?” or “is life insurance mandatory for a mortgage?” In the UK, the answer is generally no — you can get a mortgage without life insurance and you can have a mortgage without life insurance — but many borrowers choose cover to reduce the financial impact on their families if the worst happens.

When to arrange building insurance
When to buy building insurance when buying a house
For most purchases with a mortgage, you should have buildings insurance in place by exchange of contracts, not just by completion (sometimes called building insurance when buying a house). At exchange, you become legally responsible for the property, so any damage from that point needs to be insured.
Arranging cover at the exchange:
- Meets your lender’s condition.
- Protects you if something happens between exchange and completion.
Many buyers ask, “When to buy building insurance when buying a house?” – in most cases, your solicitor and broker will both advise arranging it at the exchange to avoid gaps. If you are wondering specifically “when to get building insurance when buying a house”, the safest approach is to start the policy at exchange.
Steps when shopping for building insurance
- Use the survey or valuation to find the recommended rebuild cost.
- Get quotes from several insurers, comparing not only price but cover limits, exclusions and excesses.
- Check that the policy start date, rebuild sum and other details meet your lender’s requirements.

What insurance do you need when buying a house?
In the UK, if you are asking “what insurance do you need when buying a house UK” or “what insurance do I need when buying a house?”, you may want to consider several types of cover:
- Buildings insurance: Effectively mandatory with a mortgage to protect the structure and satisfy lender conditions.
- Contents insurance: Optional but advisable to protect your belongings once you move in.
- Life insurance: Not required by lenders, but it can ensure the mortgage is cleared or reduced if you die.
- Critical illness cover: Can provide a lump sum if you are diagnosed with specified serious illnesses, helping with mortgage payments or reducing debt.
- Income protection: Longer-term cover that can pay an income if you cannot work due to illness or injury.
If you are wondering “what insurance do I need for a mortgage?”, focus first on buildings cover at exchange, then consider contents and protection based on your income, dependants, savings and existing benefits. In short, house insurance when buying a house usually means prioritising buildings cover at exchange, then adding contents and any protection as needed. For many buyers, combining the right mortgage with appropriate protection is best considered together; our mortgage protection page explains how these policies can sit alongside your mortgage.
Is home insurance compulsory?
There is no legal requirement in the UK to have home insurance as a whole, but:
- Buildings insurance is effectively compulsory if you have a mortgage, because lenders almost always require it as a condition of lending.
- Contents insurance is optional, but can prevent significant personal financial loss if you suffer theft, fire or other damage to your belongings.
Many people frame this as “Is house insurance compulsory?” or “do I need home insurance?” In practical terms, lenders generally require buildings cover when a mortgage is involved. Without appropriate cover, you would need to fund repairs, rebuilding and replacement of possessions yourself. For most households, the potential cost makes comprehensive home insurance a key part of long-term financial security.
