When Do You Need Buildings Insurance? A home can become your responsibility before it becomes your address.
That distinction matters when buying a property.
Many buyers expect buildings insurance to begin on completion day. However, responsibility may pass earlier under the purchase contract.
Therefore, arranging cover should not be left until the removal van arrives.
When Should Buildings Insurance Start?
- Mortgage lenders normally require buildings insurance.
- Cover may need to start when contracts are exchanged.
- The position can differ in Scotland and Northern Ireland.
- Your conveyancer should confirm when the property becomes your responsibility.
- Leasehold buildings insurance may already exist under a block policy.
- New-build properties may have specialist arrangements.
- Buildings insurance should cover the rebuild cost, not the market value.
- Contents cover normally becomes relevant when your belongings enter the property.
Why Buildings Insurance Matters During a Purchase
Buildings insurance protects the physical structure of a property.
Depending on the policy, this can include:
- Walls
- Roofs
- Floors
- Windows and doors
- Fitted kitchens
- Fitted bathrooms
- Permanent fixtures
- Garages and certain outbuildings
Policies usually protect against specified events. These may include fire, flood, storm, escape of water, vandalism and subsidence.
The precise cover depends on the policy wording.
Buildings insurance is not generally required by law. However, it is normally a condition of a residential mortgage.
The lender has a financial interest in the property because it provides security for the loan.
Do You Need Buildings Insurance From Exchange of Contracts?
In England and Wales, a buyer can become legally committed to the purchase when contracts are exchanged.
The purchase contract may place the property’s risk with the buyer from that point.
This means you could remain legally required to complete the purchase if the property is damaged before completion.
For that reason, buildings insurance may need to begin on the exchange date.
Do not assume that the seller’s policy will protect your interest.
Your conveyancer should confirm:
- When risk passes under the contract
- Whether insurance must begin at exchange
- The lender’s insurance requirements
- Whether any existing policy remains relevant
- Whether unusual contract conditions apply
The exchange and completion dates may be several weeks apart. Sometimes they happen on the same day.
Your insurance start date should reflect the legal arrangement rather than the expected moving date.
What Happens on Completion Day?
Completion is when the purchase funds transfer and legal ownership changes.
You normally receive the keys after completion.
Your buildings insurance should already be active if responsibility passed at exchange.
You should check that the policy details remain accurate before completion. This includes:
- The insured address
- The start date
- The property type
- The construction method
- The number of bedrooms
- The rebuild value
- Intended occupancy
- Security information
- Previous claims
- Any planned building work
Incorrect information could affect future claims.
Is the Position Different in Scotland?
The Scottish homebuying process differs from the process in England and Wales.
A purchase becomes legally binding when missives are concluded. The contract should establish when risk passes to the buyer.
The insurance start date should follow the solicitor’s advice and the mortgage lender’s conditions.
Buyers should not rely on general online guidance alone. The legal documents for the particular purchase remain important.
What About Northern Ireland?
The buying process in Northern Ireland also has its own legal stages.
Your solicitor should confirm when you become responsible for the property and when buildings cover must begin.
The lender may require evidence of insurance before releasing mortgage funds.
What Does the Mortgage Lender Check?
A lender may ask for confirmation that suitable buildings insurance is in place.
The lender may consider:
- The insurer
- The policy start date
- The insured property
- The rebuild amount
- The main insured risks
- Any significant exclusions
- Whether its interest is noted, where required
You can usually choose your own insurer. You are not normally required to buy the lender’s policy.
However, the cover must meet the mortgage conditions.

How Much Buildings Cover Is Needed?
Buildings cover should generally reflect the estimated cost of rebuilding the property.
This is known as the rebuild or reinstatement cost.
It is different from:
- The purchase price
- The mortgage balance
- The market value
- The deposit
- The land value
Rebuilding can involve more than bricks and labour.
The estimate may also account for:
- Demolition
- Site clearance
- Surveyors
- Architects
- Engineers
- Planning requirements
- Current building standards
- Professional fees
A rebuild estimate may appear in the mortgage valuation or property survey.
Unusual, listed or non-standard homes may require a professional reinstatement assessment.
When Should Contents Insurance Start?
Contents insurance protects movable possessions rather than the building.
This can include:
- Furniture
- Clothing
- Televisions
- Computers
- Appliances
- Jewellery
- Books
- Personal belongings
You may want contents cover to begin when your possessions become exposed to risk at the new property.
Some policies provide limited cover while belongings are moved by a professional removal company. However, conditions and limits can apply.
Check whether the policy covers:
- Possessions in transit
- Temporary storage
- Accidental damage during removal
- High-value items
- Items left at the previous home
- Belongings at both addresses
Do not assume every moving-related loss is covered.
What If You Are Buying a Leasehold Flat?
A freeholder or managing agent often arranges buildings insurance for the whole block.
The leaseholder then contributes through the service charge.
Before arranging separate buildings insurance, ask for:
- The block policy schedule
- The insured risks
- The buildings sum insured
- The policy excess
- Details of communal-area cover
- The claims procedure
- Confirmation of your lender’s interest
The FCA explains that leasehold buildings insurance costs can reflect the risks associated with the whole building. This can include construction and cladding concerns. Read the FCA’s leaseholder buildings insurance guidance.
You will normally remain responsible for arranging contents insurance.
What If You Are Buying a New-Build Home?
A builder may remain responsible for the property before legal completion.
However, this does not remove the need to check the lender’s requirements.
New-build warranties and buildings insurance perform different roles.
A warranty may cover certain structural defects. Buildings insurance covers specified events under the policy.
Your solicitor should confirm when insurance must start.
You should also disclose:
- Whether construction is complete
- Whether work continues nearby
- When you will occupy the property
- Whether the home will initially stand empty
- Whether any alterations are planned
What If Completion Is Delayed?
Tell the insurer if the expected completion date changes.
The action needed depends on whether cover has started and whether contracts have been exchanged.
The insurer may:
- Change the start date
- Extend temporary arrangements
- Confirm that existing cover remains valid
- Ask for updated information
Do not cancel cover without checking who carries the property risk.
A delay does not necessarily reverse the legal responsibilities created at exchange.
What If the Property Will Be Empty?
Standard home insurance policies often restrict cover when a property remains unoccupied beyond a stated period.
An insurer may define unoccupied as nobody normally living at the property.
Conditions may include:
- Regular inspections
- Maintaining heating
- Turning off the water
- Securing doors and windows
- Removing post
- Reporting the unoccupied period
Reduced cover or a specialist policy may apply.
Tell the insurer if renovations, delayed moving arrangements or other circumstances will leave the property empty.
Buildings and Contents Insurance Before Moving
Insurance is one part of the wider moving process.
You should also consider:
- Mortgage approval
- The property survey
- Exchange and completion dates
- Removal arrangements
- Utility transfers
- Redirecting post
- Protecting valuable possessions
- Updating security
- Reviewing personal protection
Our moving house mortgage guide explains the wider financial points involved.
Questions to Ask Before Exchange
Before exchanging contracts, confirm:
- When does responsibility for the property pass to me?
- When must the policy begin?
- What rebuild amount should I use?
- Does the lender have minimum requirements?
- Is the property built using standard materials?
- Will it be occupied immediately?
- Is there existing block insurance?
- Are renovations planned?
- Does the policy cover possessions during the move?
- What excess applies?
The policy should reflect the property you are buying, not an assumed version of it.
Protecting the Property at the Right Time
A home purchase involves several dates.
The insurance date should follow legal responsibility, lender conditions and the property’s circumstances.
Completion may be the visible milestone. Yet exchange can be the point when the financial risk changes.
Confirm the position with your conveyancer. Then arrange suitable cover before that responsibility begins.

Frequently Asked Questions
Is buildings insurance needed before completion?
It may be. In England and Wales, responsibility can pass at exchange. Your conveyancer should confirm the correct start date.
Can I wait until moving day?
You should not wait if you become responsible earlier. Your lender may also require evidence of cover before completion.
Does the seller’s insurance cover the buyer?
You should not assume it does. The seller’s policy protects their own insured interest and remains subject to its terms.
Can a mortgage lender choose my insurer?
You can normally choose your own insurer. However, the policy must meet the lender’s requirements.
Do I need buildings insurance for a leasehold flat?
The freeholder or managing agent often arranges block insurance. Check the lease and policy before buying separate cover.
Is a new-build warranty the same as buildings insurance?
No. A warranty may cover specified structural defects. Buildings insurance protects against insured events such as fire or storm damage.
