Key points

  • Your offer letter sets the insurance conditions. In one lender’s self-build mortgage, building insurance and mortgage protection must be in place before drawdown, with a free choice of provider.
  • That lender’s interest-only option needs life cover for 103% of the loan. This is a condition of that option, rather than a rule for every lender.
  • Other lenders set their own conditions. The letter of offer is the document that counts.
  • Confirm any structural warranty requirement in your offer and ask the lender which policies it accepts.

Check which insurance policies your lender needs and when they must start before arranging your first drawdown. Your offer letter sets the conditions; get any uncertainty resolved in writing and give the requirements to your broker. For the wider picture see self-build insurance in Ireland and the self-build mortgage guide.

Which risks need cover?

A normal house purchase mortgage is secured on a finished building. A self-build mortgage is secured on a field, then on a foundation, then on a half-built shell, with money released as work is certified. At every stage the lender has paid out against something that fire, flood, storm or theft could damage or destroy. Your offer’s insurance conditions address three separate risks:

Risk Typical answer Who it protects
The building is damaged or destroyed before or after completion Building insurance (during construction, usually a self-build or course-of-construction policy) You and the lender, whose security is the building
You die before the loan is repaid Mortgage protection, a form of life cover Your family and the lender
The finished house has hidden defects Structural or latent defects warranty, where the lender asks for one You, and in practice the lender’s security

Check each type of cover separately. A quote for building insurance does not include mortgage protection or structural defects cover unless it expressly says so.

A worked example of one lender’s conditions

One lender’s published self-build mortgage conditions require building insurance and mortgage protection before drawdown, with a free choice of provider. For its approved interest-only option, life cover must be 103% of the loan. These terms illustrate what an offer can require; check your own lender’s conditions rather than applying this example to every mortgage.

For this particular mortgage, there are three checks to make:

  1. Compare providers. You are not tied to the bank’s own products, so compare quotes from a broker rather than accepting the first one offered at the point of sale.
  2. The deadline is drawdown, not completion. This lender requires the first drawdown within 6 months of the offer letter. Arrange the policies to meet both the lender’s drawdown conditions and the actual start of site risk; the drawdown deadline is not permission to leave earlier work uninsured.
  3. The 103% figure is specific to interest-only. It is the amount of life cover required, not the amount of the loan. On an illustrative €400,000 loan, 103% is €412,000. Ask the lender why it requires the extra 3% and what cover and policy term it will accept.

How insurance fits the stage payments

In the same lender example, the mortgage is released in four stages. Each depends on certification by a professional you have assigned, and the last depends on documents that only exist when the house is finished.

Stage Released when What can go wrong in the meantime
Floor level Foundations are certified Flooding of excavations, theft of materials, damage to the footings
Roof level The shell or frame is certified Storm damage to an unroofed structure, fire in a timber frame
Finished The property is habitable, with plasterwork finished and water and electricity connected Water damage, theft of fittings, electrical fire
Post completion A final valuation, Declaration of Identity, Certificate of Compliance, planning contribution confirmation and final Building Energy Rating (BER) certificate are in Defects that only show later

For this mortgage, the minimum final drawdown is 10% of the total mortgage or €15,000, whichever is higher. The final drawdown must be within 18 months of the first and no more than 24 months from the offer letter. A project that overruns has to keep its insurance alive for the whole period, so build renewal dates into your programme. See staged drawdown explained for how the stages work in practice.

Section 126 of the Consumer Credit Act 1995 generally requires the lender to arrange life assurance to repay the estimated outstanding principal on death. Its exceptions include a home not intended as the borrower’s or dependants’ principal residence, certain cases where insurance is unavailable or only available at a significantly higher premium, borrowers over 50 at approval, and sufficient existing life assurance. An exception does not guarantee that a lender will lend without cover: confirm its requirements in writing.

Mortgage protection covers death under the policy terms. Basic life cover does not replace income lost through unemployment or illness; optional serious-illness benefits have their own conditions.

There are two common shapes of cover:

  • Reducing term: the amount covered falls as you pay down the loan. The Competition and Consumer Protection Commission (CCPC) describes this as the most common and cheapest type.
  • Level term: the amount insured and the premium stay the same, and anything left after the mortgage is cleared goes to your estate.

During interest-only repayments the loan principal is not falling. Ask your adviser to check that the cover schedule matches the outstanding debt throughout construction and the later repayment period. The 103% condition in the lender example applies to that approved interest-only option; do not assume it applies to every lender or policy.

If you are a couple, check whether the lender expects a joint-life policy or two single-life policies, and whether the cover is set against the whole loan or each person’s share.

Building insurance: what to ask before you buy

Lenders say “building insurance” or “property insurance”, but a self-builder needs something more specific than a standard home policy, because a standard policy usually assumes a finished, occupied house. Cover during construction is normally arranged as a self-build or contract works policy; see contract works and public liability. Questions worth asking:

  • Does the policy cover the structure from the first day on site, including materials stored on site and in transit?
  • What valuation basis and sum insured does this construction policy require, including during staged work? Under-insurance can reduce a payout, as described in making a claim.
  • What happens at practical completion? Confirm the construction policy’s actual end trigger, including any occupation condition, and arrange the next policy before that cover ends.
  • If you are project managing rather than hiring a main contractor, does the policy still apply, and who is the named insured?

The lender’s own interest

Ask whether the lender needs its interest noted on the policy and what wording it accepts. Have the insurer explain what that wording does for cancellation notices and claim payments; recording an interest alone should not be treated as a promise of particular rights. Obtain the agreed documents before drawdown.

Structural defects cover

Do not treat building insurance or mortgage protection as structural defects cover. One provider offers separate policies for houses and low-rise developments and for mid- and high-rise apartments. That does not establish whether a one-off self-build is eligible or on what terms.

The published conditions used in the lender example do not establish a structural warranty requirement. Ask your lender in writing whether it requires one, which policies it accepts and when it needs the documents. Ask a broker to confirm whether cover is available for your build. Read more in structural defects cover.

Arrange the certificates alongside the policies

Several of the documents lenders ask for are professional certificates rather than policies, and they can be a bigger source of delay than the insurance. The lender in the worked example requires an assigned qualified professional — an architect, engineer or building surveyor — for stage reports, and an Assigned Certifier (the professional you appoint to inspect the build and sign it off) for the Certificate of Compliance and the Declaration of Identity. Check that whoever signs for you carries professional indemnity cover, and whether your lender states a minimum.

Common mistakes

  • Buying mortgage protection too late. Underwriting can take time, particularly if a medical report is needed, and the policy must be in place before the first drawdown.
  • Assuming a house policy will do. A standard home policy may not cover a site with no roof.
  • Letting the policy lapse during an overrun. A construction policy may have a fixed project term rather than annual renewal. Check its expiry and extension procedure before an overrun; a lapse can delay a payment.
  • Not telling the insurer about a change. Switching from a builder to project managing, adding an extension or changing the scope changes the risk. Tell your insurer and your lender.
  • Relying on a verbal answer. If a lender or provider says a policy is acceptable, get it in writing.

Questions to put to your lender

  1. Which types of insurance must be in place, and by when?
  2. Is there a minimum level of cover, for example the full rebuild cost?
  3. Does the lender need its interest noted on the building policy?
  4. Is a structural warranty or latent defects policy required, and which providers do you accept?
  5. What happens to the cover requirements if I switch from a builder to project managing?
  6. Is life cover set against the whole loan, and does the amount differ for interest-only periods?
  7. Which professionals do you accept for stage certification, and do they need a minimum level of indemnity cover?

Get the answers in writing, and give a copy to your broker so that the quotes match.

Keep the evidence

Keep every certificate of insurance and renewal date in one folder, paper or digital. When you reach a drawdown, a lender’s valuer or solicitor may ask to see them. Diarise each renewal at least a month ahead, because a lapse mid-build is the kind of thing that can delay a payment. If your circumstances change, such as a new lender after a mortgage switch, restart this checklist from the top, since the new lender’s conditions replace the old ones.

Common questions

Do lenders require a structural warranty on a self-build?

Check your own offer letter and get the lender’s answer in writing. The lender example below does not establish a structural warranty requirement or whether a one-off self-build is eligible for a particular defects policy. Ask a broker about availability too.

When must the policies be in place?

In the lender example below, building insurance and mortgage protection must be in place before drawdown. Your lender may set different conditions or deadlines, so check your offer letter. Arrange site cover for when the risk starts, even if drawdown comes later.
