Indemnity insurance when buying a house

Indemnity insurance is a quick, low-cost way to deal with certain legal defects in a property purchase. It does not fix the problem, it protects you financially if it ever causes a loss. Here is when you need it, what it costs and who pays.

In short

Legal indemnity insurance is a one-off policy that protects a buyer (and their lender) against financial loss arising from a specific legal defect in a property, for example missing building regulations sign-off, a breach of a restrictive covenant, an unknown right of way, or a chancel repair liability. It is typically a single premium of around £20–£300+ depending on the risk and property value, with cover lasting indefinitely and usually passing to future owners. The seller usually pays because the defect existed before sale. Importantly, indemnity insurance does not cure the underlying problem or guarantee the work was done correctly, it only pays out if the defect leads to a claim or enforcement action.

What indemnity insurance actually does

During conveyancing, your solicitor checks the property's legal title and paperwork. Sometimes a gap or defect emerges, perhaps an extension was built without building regulations approval, or there is a restrictive covenant that may have been breached.

Rather than spending months and significant fees trying to fix the issue (for example tracking down a long-gone freeholder or applying for retrospective consent), a legal indemnity policy offers a fast, inexpensive alternative. It is a one-off payment that compensates you if the defect ever results in a financial loss, such as a third party enforcing a covenant or a council taking action.

The crucial point buyers often miss: indemnity insurance manages the risk, it does not remove it. It will not pay for the building work itself, and it does not confirm the property is safe or compliant.

Common types of property indemnity insurance

Each policy covers a specific legal risk uncovered during conveyancing.

Policy typeRisk it coversTypical cost
Building regulationsWork done without building control sign-off£20–£200
Restrictive covenantBreach of a covenant a third party could enforce£50–£300+
Lack of planning permissionAlterations done without planning consent£50–£250
Absent landlord / freeholderUnable to locate the freeholder to confirm lease terms£100–£400
Chancel repair liabilityLiability to fund local church repairs£20–£60
Lack of access / right of wayNo formal legal right to access the property£100–£400+

Premiums rise with the property value and the assessed level of risk; cover is a single, lifetime payment.

When indemnity insurance is commonly used

Your conveyancer may suggest a policy when:

  • An extension, loft conversion or window replacement lacks building regulations completion certificates.
  • There is a restrictive covenant and no easy way to get retrospective consent.
  • The freeholder of a leasehold property cannot be traced.
  • Searches reveal a potential chancel repair liability.
  • There is no documented legal right of access across neighbouring land.
  • A lender requires cover before it will release the mortgage funds.

Do not alert the other party first

Most indemnity policies are invalidated if you contact the council, freeholder or beneficiary of a covenant about the defect, because doing so can increase the chance of a claim. Always take your solicitor's advice before approaching anyone about the issue.

How the process works

  1. 1. Defect identified

    Your solicitor flags a legal gap during their title and search review.

  2. 2. Decide the approach

    Choose between fixing the issue (e.g. regularisation) or taking out indemnity insurance, your solicitor advises on the trade-offs.

  3. 3. Policy arranged

    Your solicitor obtains a quote and the policy, usually completed in days, with the seller typically paying the premium.

  4. 4. Cover in place at completion

    The single premium is paid, cover starts, and it generally passes to future owners and your lender.

Who pays and is it worth it?

Because the defect usually pre-dates your purchase, the seller normally pays for the policy, it is part of selling a property with a legal imperfection. This is something your solicitor negotiates on your behalf.

Indemnity insurance is generally good value when the risk of enforcement is low and the alternative (fixing the defect) is slow or expensive. But weigh it carefully for safety-related issues: a policy covering missing building regulations pays out for enforcement action, not for putting right unsafe work. If you have doubts about the quality or safety of building work, a survey or proper regularisation may be the wiser route.

Common questions

What is indemnity insurance when buying a house?

It is a one-off insurance policy that protects you and your lender against financial loss caused by a specific legal defect in the property, such as missing building regulations sign-off or a restrictive covenant. It does not fix the defect; it pays out if the defect leads to a claim or enforcement action.

How much does property indemnity insurance cost?

Most policies are a single premium of around £20 to £300, though higher-value properties or higher-risk issues can cost more. Chancel repair cover is often under £60, while access or absent-landlord policies can run to several hundred pounds.

Who pays for indemnity insurance, buyer or seller?

Usually the seller, because the legal defect existed before the sale. Your solicitor typically negotiates for the seller to cover the premium, though arrangements can vary by transaction.

Is indemnity insurance a good idea?

It is often a sensible, cost-effective solution when the risk of enforcement is low and fixing the defect would be slow or expensive. It is less suitable where safety is the concern, because it covers financial loss from enforcement, not the cost of correcting unsafe work.

Does indemnity insurance fix the problem?

No. It only provides financial compensation if the defect causes a loss. It does not regularise unauthorised building work, remove a covenant, or confirm that work was done safely or correctly.

How long does indemnity insurance last?

Most policies provide cover indefinitely from a single premium and usually pass to future owners. Because it is a one-off payment, there are no ongoing renewals.

Can I challenge or fix the defect instead?

Yes. Alternatives include applying for retrospective building regulations approval (regularisation), seeking retrospective planning permission, or obtaining consent from the party who could enforce a covenant. These can be slower and more expensive, and contacting the other party can invalidate an indemnity policy, so take legal advice first.

Will my mortgage lender accept indemnity insurance?

Often yes, lenders frequently accept indemnity insurance as a way to deal with minor legal defects, and some require it before releasing funds. Your conveyancer will confirm the policy meets your specific lender's requirements.
