IBGs Explained

What is an Insurance Backed Guarantee?

An Insurance Backed Guarantee provides an additional layer of protection behind a contractor's own written guarantee, helping give property owners, developers and other interested parties greater confidence in qualifying building and improvement works.

Insurance protection behind the contractor's guarantee

When a contractor completes qualifying work, they may issue their customer with a guarantee covering that work for a stated period. An Insurance Backed Guarantee (IBG) is an insurance policy designed to sit behind that original guarantee.

Depending on the policy terms and the circumstances of a claim, the IBG can provide protection where the original contractor is no longer able to honour its guarantee, for example following the contractor ceasing to trade.

IBGs are commonly used across the UK construction and property improvement sectors and may be requested by homeowners, developers, lenders, structural warranty providers, local authorities, funding bodies or other parties involved in a project.

The exact scope, duration and circumstances in which an Insurance Backed Guarantee responds will depend on the insurer, work type and individual policy wording.

What does an IBG protect?

An IBG provides insurance protection connected to the contractor's qualifying guarantee. The precise protection provided depends on the policy wording, insured works, guarantee period and circumstances giving rise to a claim.

Why might an IBG be required?

Insurance Backed Guarantees may form part of a lender, structural warranty, funding, tender or contractual requirement. Contractors may also offer them voluntarily to provide their customers with additional reassurance.

Who can arrange an IBG?

IBGs can be arranged for eligible contractors and construction businesses across many specialist and general trades, subject to the insurer's underwriting requirements and the type of work being guaranteed.

i
The terms of an Insurance Backed Guarantee can vary.

Cover is subject to insurer acceptance, policy terms, conditions, exclusions and the qualifying contractor guarantee. Peacock can help you understand the cover available for your particular work type and requirements.

When You May Need an IBG

When is an Insurance Backed Guarantee required?

An Insurance Backed Guarantee may be requested as part of a construction contract, property transaction, funding arrangement or warranty requirement. The exact requirement will depend on the work, project and organisation requesting the guarantee. Peacock can help contractors and developers establish what Insurance Backed Guarantee protection may be suitable.

Requirement 01

Mortgage lenders and development finance

A mortgage lender, development lender or funding provider may ask for evidence of suitable guarantee protection before lending against a property or funding a project. The precise insurance and warranty requirements should always be checked with the party providing the finance.

Requirement 02

Structural warranty providers

A structural warranty provider may require an Insurance Backed Guarantee for particular elements of work before accepting or completing its warranty arrangements. This can arise where specialist contractors undertake roofing, waterproofing, groundworks, cladding or other qualifying works.

Requirement 03

Tenders and contractual requirements

Developers, principal contractors, local authorities, commercial clients and other organisations may include Insurance Backed Guarantee requirements within a tender or construction contract. Arranging the required protection can therefore form part of the contractor's obligations before or after the work is completed.

Requirement 04

Providing additional reassurance to clients

An IBG does not always have to be imposed by another organisation. Eligible contractors may choose to offer Insurance Backed Guarantee protection alongside their own written guarantee to provide customers with additional insurance protection, subject to the terms of the policy.

Completed Work

Can you arrange a retrospective Insurance Backed Guarantee?

In some circumstances, a retrospective Insurance Backed Guarantee can be considered for qualifying work that has already been completed where an IBG was not put in place at the time. The insurer will normally need sufficient information about the contractor, completed work and underlying guarantee before deciding whether cover can be offered.

Refinancing or lender request

i
Always check the requirement before arranging cover

Lenders, warranty providers, clients and other organisations can have different requirements. Insurance Backed Guarantee cover is subject to insurer acceptance and the applicable policy terms, conditions and exclusions. If another party has specifically requested an IBG, provide Peacock with their requirements so suitable cover can be considered.

Structural Waterproofing & Basement IBGs

Cover may be available for qualifying structural waterproofing, basement tanking and below-ground protection systems where long-term guarantee protection is required.

Cladding & Facade Insurance Backed Guarantees

Insurance backing may be considered for qualifying cladding, facade and external envelope works, subject to the construction method, materials, contractor and insurer acceptance.

Groundworks, Piling & Underpinning IBGs

Suitable Insurance Backed Guarantees may be considered for specialist groundworks, piling, underpinning and drainage works where an insurable contractor guarantee is in place.

Work type alone does not determine whether cover is available

The IBG Process

How Does an Insurance Backed Guarantee Work?

Arranging an Insurance Backed Guarantee does not need to be complicated. Peacock works with contractors and construction businesses to understand the guarantee required, obtain the information needed by the insurer and arrange appropriate Insurance Backed Guarantee protection where cover is available.

Getting Started

Tell us about your business and the work

Start by telling Peacock about your business, trade and the type of work for which you need an Insurance Backed Guarantee. If a lender, structural warranty provider, client or other party has specified a requirement, provide those details too.

New and existing contractors can make an enquiry
01
02
Initial Assessment

Contractor and work information is reviewed

Information about the contractor and proposed work is considered against the insurer's underwriting criteria. This can include the contractor's experience, trading history, nature of the work and the guarantees being provided to customers.

Requirements can vary according to insurer and work type
Underlying Guarantee

The contractor's guarantee is established

The IBG is designed to provide insurance protection behind an eligible underlying contractor guarantee. The guarantee wording, duration, work being guaranteed and other relevant details may therefore need to be established before insurance protection can be arranged.

The IBG and contractor guarantee are separate documents
03
04
Underwriting

The insurer considers the risk

The insurer assesses the information provided and decides whether Insurance Backed Guarantee protection can be offered and on what terms. Additional information may be requested where necessary before a decision can be made.

Cover remains subject to insurer acceptance
Certification

The Insurance Backed Guarantee is issued

Once the required information has been accepted and the relevant requirements have been satisfied, an Insurance Backed Guarantee certificate can be issued for the qualifying works. Same-day certification may be available for eligible cases.

Certification times depend on eligibility and information supplied
05
06
Protection

Insurance protection continues for the guarantee period

Subject to the terms of the policy, the Insurance Backed Guarantee remains in place for the insured guarantee period and may provide protection in circumstances specified by the policy where the original contractor is unable to honour its qualifying guarantee.

Policy terms, conditions and exclusions apply
The Outcome

A contractor guarantee supported by separate insurance protection

The customer receives the contractor's underlying guarantee together with the applicable Insurance Backed Guarantee documentation. This provides a clearly documented arrangement showing the original contractor guarantee and the separate insurance protection supporting it, subject to the applicable policy terms.

The exact IBG process can vary

Understanding the Difference

Insurance Backed Guarantee vs Contractor Guarantee vs Structural Warranty

These terms are sometimes used together, but they describe different forms of protection. Understanding the distinction can help contractors, developers and property owners establish what documentation or insurance may be required for a project.

Insurance Protection

Insurance Backed Guarantee

Separate insurance designed to support an eligible contractor guarantee.

Provided by
An insurer, subject to underwriting and policy terms.
Purpose
To provide insurance protection behind a qualifying contractor guarantee in circumstances specified by the policy.
Duration
Depends on the policy and underlying guarantee. Longer-term periods may be available for qualifying work.
Best understood as

Insurance sitting behind an eligible contractor's guarantee.

Contractor Promise

Contractor Guarantee

The original written guarantee provided by the contractor for qualifying work.

Provided by
The contractor or construction business that undertook the work.
Purpose
To state the contractor's obligations in relation to the work covered by its guarantee.
Duration
Determined by the contractor's guarantee wording and the nature of the work.
Best understood as

The contractor's own written commitment relating to the work.

Property Warranty

Structural Warranty

A separate form of protection generally associated with specified structural defects in qualifying developments.

Provided by
A specialist structural warranty provider or insurer.
Purpose
To provide protection in relation to specified defects or risks within the structural warranty terms.
Requirement
Often associated with new-build, conversion or development projects and may be required by a lender.
Best understood as

Separate structural protection for a qualifying property or development.

How They Relate

An IBG can support a contractor guarantee without replacing it

The contractor guarantee, Insurance Backed Guarantee and any structural warranty should be considered as separate documents with different purposes.

1
Contractor completes the work
Qualifying works are carried out
2
Contractor guarantee is provided
The contractor issues its written guarantee
3
Insurance Backed Guarantee supports it
Subject to the applicable insurance terms
i
The correct protection depends on the requirement

An Insurance Backed Guarantee should not be assumed to replace a structural warranty, and a structural warranty should not be assumed to replace an IBG or the contractor's own guarantee. If a lender, warranty provider, client or other organisation has specified particular documentation, their exact requirement should be checked. Insurance cover remains subject to insurer acceptance and the applicable policy terms, conditions and exclusions.

Not sure which guarantee or protection you have been asked for?

Tell Peacock what has been requested and provide any lender, warranty provider or contractual requirements you have received. Our team can help establish the Insurance Backed Guarantee options available.

Lenders & Warranty Providers

Insurance Backed Guarantees for Lender & Structural Warranty Requirements

Contractors and developers are sometimes asked to provide an Insurance Backed Guarantee as evidence of additional protection behind qualifying works. Requirements can differ between mortgage lenders, development funders, structural warranty providers and individual projects.

Understanding the Requirement

Why might a lender or warranty provider ask for an IBG?

Where specialist work forms part of a property or development, a lender, structural warranty provider or other interested party may want evidence that the contractor's written guarantee has suitable insurance protection behind it.

An Insurance Backed Guarantee can provide that separate insurance protection, subject to the insurer's acceptance and the applicable policy terms.

The exact requirement can depend on the nature of the work, property, funding arrangement, warranty provider and the organisation reviewing the project. Where you have been given a written specification or request, Peacock can use that information when considering the IBG options available.

From Request to Evidence

What happens when a lender or warranty provider requests an IBG?

Providing the original requirement at the outset helps establish what Insurance Backed Guarantee protection needs to be considered.

Step 01

Requirement received

A lender, warranty provider or other party specifies that guarantee or insurance evidence is required.

Step 02

Requirement reviewed

Provide Peacock with the request or specification so the relevant IBG requirement can be understood.

Step 03

Cover considered

The contractor, work and guarantee are considered against the insurer's underwriting requirements.

Step 04

Certification issued

Where accepted and all requirements are satisfied, the applicable IBG documentation can be issued.

Information that may be relevant to the requirement

The information needed will vary, but the following can help establish whether suitable Insurance Backed Guarantee cover can be considered.

01

Type of work

Details of the construction, treatment, installation or specialist works being guaranteed.

02

Contractor guarantee

The wording, duration and scope of the underlying guarantee may be relevant to the insurance.

03

Requesting party

Details of the lender, warranty provider, funder or organisation requesting the evidence.

04

Required period

Any specified guarantee period or other requirement should be provided when seeking cover.

Lender Certification

Need evidence of Insurance Backed Guarantee protection?

Where a suitable IBG has been accepted and the required information is complete, documentation can be provided as evidence of the applicable Insurance Backed Guarantee. Same-day certification may be available for eligible cases, subject to insurer requirements and the information supplied.

Same-day certification may be available
i
Acceptance remains the decision of the lender or requesting organisation

Peacock cannot guarantee that any particular Insurance Backed Guarantee, insurer or documentation will be accepted by every lender, warranty provider or other organisation. Their requirements should be confirmed directly where necessary. Insurance Backed Guarantee cover is also subject to insurer acceptance and the applicable policy terms, conditions and exclusions.

Have you been asked to provide an Insurance Backed Guarantee?

Tell us who has requested it, what work is being guaranteed and provide any written lender or warranty requirements you have received.

Completed Works

Retrospective Insurance Backed Guarantees

If qualifying work has already been completed without an Insurance Backed Guarantee being arranged at the time, retrospective cover may still be considered. This can arise during a property sale, refinancing, lender review or where additional evidence of guarantee protection is subsequently requested.

Retrospective IBG Cover

Can an Insurance Backed Guarantee be arranged after the work is completed?

In some circumstances, yes. A retrospective Insurance Backed Guarantee may be considered where qualifying work was completed previously but suitable insurance backing was not arranged at the time.

The insurer will usually need sufficient information about the contractor, completed work, original guarantee and circumstances surrounding the request before deciding whether retrospective protection can be offered.

Availability will depend on the individual case and insurer underwriting requirements.

Completed qualifying works may be considered
Existing contractor guarantee may be relevant
Lender or warranty requests can be considered
Cover remains subject to insurer acceptance

Property Sale

A buyer, solicitor or other interested party may request evidence relating to previous works.

Refinancing or Mortgage

A lender may request additional guarantee evidence when refinancing or reviewing security.

Structural Warranty Review

A warranty provider may request suitable evidence in relation to specialist completed works.

Missing Previous Evidence

An IBG may not have been arranged originally and additional documentation is now required.

Retrospective Process

How is a retrospective IBG considered?

Because the work has already been completed, the insurer may need to understand both the original work and the reason Insurance Backed Guarantee protection is now required.

01

Tell us what was completed

Provide details of the work, contractor and approximate completion date.

02

Existing evidence is reviewed

The underlying guarantee and other available supporting information can be considered.

03

Insurer assesses the case

The insurer decides whether retrospective Insurance Backed Guarantee protection can be offered.

04

Documentation can be issued

Where accepted and requirements are met, applicable IBG documentation can be provided.

What information may be needed for a retrospective IBG?

The exact requirements will vary, but having as much information as possible about the completed work can help the insurer assess the request.

01

Details of the work

The nature, location and scope of the qualifying works already completed.

02

Completion date

When the work was completed and, where relevant, when the contractor guarantee began.

03

Contractor guarantee

A copy or details of the original written contractor guarantee may be required.

04

Reason for the request

Any lender, warranty provider, solicitor or contractual requirement should be provided.

i
Retrospective cover cannot be guaranteed

Retrospective Insurance Backed Guarantees are subject to insurer acceptance and may not be available for every contractor, work type or set of circumstances. Additional information may be requested as part of the underwriting process. Policy terms, conditions and exclusions apply.

Need an Insurance Backed Guarantee for completed work?

Tell us what work was completed, when it was carried out and why an IBG is now required. Peacock can help establish whether retrospective cover can be considered.

Frequently Asked Questions

Insurance Backed Guarantee FAQs

Answers to some of the most common questions contractors, developers and property professionals ask about Insurance Backed Guarantees, certification, guarantee periods, retrospective cover and insurer requirements.

What is an Insurance Backed Guarantee?

An Insurance Backed Guarantee (IBG) is a specialist insurance policy designed to provide protection behind an eligible contractor's written guarantee.

Depending on the policy and circumstances, the IBG may provide protection where the contractor is no longer able to honour the qualifying guarantee. Policy terms, conditions and exclusions apply.

Is an IBG the same as the contractor's guarantee?

No. The contractor's guarantee and the Insurance Backed Guarantee are separate. The contractor provides the original guarantee relating to the qualifying work, while the IBG is separate insurance protection designed to support that guarantee.

How long can an Insurance Backed Guarantee last?

The available guarantee period depends on the work, underlying contractor guarantee, insurer and underwriting criteria. For qualifying cases, Insurance Backed Guarantee periods of up to 25 years may be available.

What types of work can be covered by an IBG?

A broad range of qualifying construction and specialist works may be considered, including roofing, damp proofing, timber treatment, structural waterproofing, basement works, cladding, glazing, groundworks, piling, structural works, renewable energy installations and general building works.

Availability depends on the insurer's underwriting criteria and the individual contractor and project.

Do mortgage lenders require Insurance Backed Guarantees?

A mortgage lender or development funder may request an IBG or other suitable guarantee evidence in connection with particular works or properties.

Requirements vary between lenders, so acceptance should not be assumed. Where a lender has made a specific request, provide Peacock with the exact requirement so suitable options can be considered.

Can a structural warranty provider ask for an IBG?

Yes. In some circumstances, a structural warranty provider may request Insurance Backed Guarantee protection in relation to particular specialist works forming part of a development.

The exact requirement should always be checked with the warranty provider because an IBG and a structural warranty are separate forms of protection.

Can an Insurance Backed Guarantee be arranged retrospectively?

In some circumstances, retrospective Insurance Backed Guarantee cover can be considered for qualifying work that has already been completed.

The insurer may need information about the contractor, work, completion date, underlying guarantee and reason the IBG is now required before deciding whether cover can be offered.

Can I get an IBG for work that was completed several years ago?

It may be possible, depending on the age and nature of the work, the contractor, available documentation and insurer criteria. Older completed works can require additional information and retrospective cover cannot be guaranteed.

How quickly can an IBG certificate be issued?

Where the contractor is eligible, the required information is available and the insurer's requirements have been satisfied, same-day certification may be available.

Timescales depend on the individual case and should not be assumed until the required information has been reviewed.

What information is needed to arrange an IBG?

The insurer may require information about the contractor, trading history, experience, work type, value of the work, underlying guarantee and required guarantee period.

If a lender, warranty provider or commercial client has specified a particular requirement, that should also be provided.

Does every contractor qualify for Insurance Backed Guarantee cover?

No. Insurance Backed Guarantee cover is subject to insurer underwriting and acceptance. The insurer may consider factors including the contractor's experience, trading history, work type, guarantee wording and other relevant information.

Is an Insurance Backed Guarantee the same as a structural warranty?

No. An IBG is designed to provide insurance protection behind an eligible contractor guarantee. A structural warranty is a separate form of protection generally associated with specified structural defects or risks in qualifying developments.

One should not automatically be assumed to replace the other.

Can an IBG help when selling or refinancing a property?

It can sometimes be relevant where a buyer, lender, solicitor or other interested party requests additional guarantee evidence relating to previous qualifying works.

Where an IBG was not arranged originally, retrospective cover may be considered subject to insurer acceptance.

Will every lender accept the same Insurance Backed Guarantee?

No. Individual lenders, funders and warranty providers can apply their own criteria and acceptance requirements.

If an organisation has requested an IBG, the safest approach is to obtain the exact requirement and provide it before cover is arranged.

How do I get an Insurance Backed Guarantee quote?

Provide Peacock with details of your business, trade, the work being guaranteed and the guarantee requirement. If another organisation has requested the IBG, include any written specification or requirement they have supplied.

Peacock can then help establish which Insurance Backed Guarantee options may be available.
