The Gap Between Signatures: Protecting a First Home From Exchange to Completion
Buying a first home is a sequence of small certainties arriving in an order that rarely feels convenient. The mortgage offer is agreed, the searches return, a completion date is proposed — and then, quite suddenly, there is a binding contract and a set of keys that will not be handed over for another week or two.
That interval is where a surprising number of first-time buyers discover a gap in their arrangements. The building they have just committed to buy becomes their responsibility to insure at the moment contracts are exchanged. Not on the day the removal van is booked. Not when the keys are collected. At exchange.
This is not a technicality to be resolved later. It is the point at which the financial consequences of a fire, a flood or a falling chimney pot pass from seller to buyer, and the point at which a mortgage lender will expect its interest in the property to be protected.
Why the risk moves before the keys
Under the standard conditions of sale used in England and Wales, the risk in a property passes to the buyer on exchange. The seller’s obligation to keep the building insured for the buyer’s benefit ends at that moment, and many sellers sensibly cancel their own cover once the contract is binding and the date is fixed.
If the property is damaged between exchange and completion, the loss generally falls on the buyer’s policy. Contracts do contain limited remedies where damage is severe, but those provisions are narrow, slow and not something a household wants to rely on in the middle of a move.
The practical instruction is therefore unglamorous but firm: buildings insurance should be in force from the exchange date, and the start date should be confirmed in writing rather than assumed from a quote.
Five assumptions worth retiring
- ‘The seller’s policy covers me until I move in.’ It does not, beyond the point of exchange. The seller is insuring their own interest while they remain the owner, and that interest ends when the contract becomes binding.
- ‘The lender has arranged it.’ Some lenders will arrange cover, particularly where a borrower has not done so, but that arrangement exists chiefly to protect the lender’s security and the premium is typically added to the mortgage. The cover and its terms deserve to be read, not just paid for.
- ‘Contents insurance will do.’ Contents cover protects what could be carried out of the property. Buildings cover protects the structure, permanent fixtures and fittings. A lender will normally require the latter.
- ‘It is leasehold, so nothing needs arranging.’ For a flat, the building is usually insured by the landlord or managing agent and recovered through the service charge. That is not the end of the matter: ask for the policy certificate, note the excess and any restrictions, and arrange contents cover for the day you move.
- ‘It can be sorted once I have the keys.’ Most straightforward properties can be quoted in minutes. Properties with a history of subsidence, flood exposure, non-standard construction, a thatched roof or a listed status may need referral, a surveyor’s report or a specialist insurer. Those conversations take weeks, not hours.
Timing traps worth building into the plan
Start quoting three to four weeks before the intended exchange, once the valuation has been carried out. That is early enough to absorb a referral and late enough to have the details that matter.
Expect the completion date to move. If it slips, the cover simply continues; the error to avoid is cancelling or downgrading cover before the keys are actually in hand.
Read the unoccupied property clause. Many policies restrict cover where a home is left empty for more than thirty consecutive days. If the property will be rewired, replastered or simply left empty while you serve notice on a rental, tell the insurer before the work begins rather than after.
Insure for rebuild cost, not purchase price. The figure required is what it would cost to rebuild the property from the ground up, excluding the value of the land. Your surveyor or a rebuild cost calculator will give a sensible starting point, and index-linked policies will keep the sum roughly in step with construction costs.
Finally, note the day of the week. An exchange concluded on a Friday afternoon is still an exchange, and the cover needs to begin that day. Confirm the start date in writing, keep the certificate with the mortgage paperwork, and check that the lender has been named as an interested party where required.
Where life and income protection fit
A mortgage is a commitment measured in decades, and the fortnight around exchange is often the first occasion on which a household seriously considers what would happen if the income paying for it stopped. Protection is rarely a condition of lending, but it is a condition of sleeping soundly.
The first step is to establish what already exists. Death-in-service cover through an employer, group income protection, contractual sick pay and any existing policies all count. Duplicating cover that is already provided is a common and expensive error, particularly for those who have recently changed jobs and not read the benefits statement.
Where a gap remains, the shape of the cover should follow the shape of the debt. A repayment mortgage is usually matched by decreasing term assurance, which reduces roughly in line with the balance. Interest-only borrowing, or a wish to leave a sum beyond the mortgage, points towards level term cover. Family income benefit, which pays a regular amount rather than a lump sum, suits households who think in monthly figures.
Income protection deserves separate consideration. It pays a proportion of salary during a period of illness or injury, and its usefulness depends on details that are easy to skim: the deferred period, which should be set against employer sick pay, the definition of incapacity, and the exclusions. For the self-employed and for contractors without sick pay, it is often the more pressing gap.
Underwriting takes time. Medical history, GP reports and referrals can add weeks, so an application begun at the point of exchange is far more likely to be in force by the first mortgage payment than one begun after the boxes are unpacked. Life policies placed in trust can be paid out without waiting for probate, which is a small administrative step with a long reach.
A checklist for the fortnight around exchange
- Obtain two or three buildings insurance quotes before exchange, with the intended exchange date as the start date.
- Confirm in writing that the policy begins on the day of exchange, not completion.
- Check the rebuild cost figure and whether the policy is index-linked.
- Read the unoccupied property clause and the escape-of-water conditions.
- If leasehold, request the block policy certificate and note the excess.
- Arrange contents cover from the day you move in.
- Review existing workplace benefits for death-in-service and sick pay.
- Apply for any life or income protection early enough to allow for underwriting.
- Place life policies in trust, and tell your solicitor the policies exist.
- Keep certificates, schedules and trust documents together with the mortgage file.
The pattern is consistent across every first purchase: the decisions taken quietly in the days before exchange tend to be the ones that matter most afterwards. Insurance is not the most exciting part of buying a home, but it is the part that keeps a difficult fortnight from becoming a difficult decade.
