Why Is A New Home Warranty Needed?

Most importantly, a new home warranty is needed to insure against structural defects which can often be extremely costly for any new homeowner to put right.

The majority of mortgage lenders will also insist that a recognised structural warranty is in place for each newly built home. Banks and building societies will often not provide mortgages until a new home warranty has been secured by the developer. This is to ensure mortgage lenders’ funds are sufficiently protected if a defect arises, and the new housing unit needs to be either partially or completely rebuilt. Our policy in this scenario would pay for these costs without the need to prove negligence.

New home warranties also make houses far more attractive for developers and future homeowners to sell. They provide the reassurance and peace of mind that cover is in place should the worst happen.

How Does Our New Home Warranty Work?

A One Guarantee new home warranty runs for a period of up to 12 years as standard. Our new home warranty is divided into three important parts:

1. Developer Insolvency Cover (optional and subject to approval)
Cover is offered during the construction phase of the build in the event of insolvency/fraud on the part of the developer. One Guarantee will either pay for the costs to finish the build or refund the deposit* paid by the consumer/purchaser. p>

*Up to 10% of the purchase price subject to a limit of £100,000

2. Defects Insurance Period (practical completion to year 2)
It is the developers responsibility to address any structural defects in the first two years following the practical completion of the build. Redress may be offered to purchasers under the Consumer Code for New Homes for any non-structural related issues.

3. Structural Insurance Period (years 3 to 12)
Full risk transfer is provided in years 3-12, meaning that any structural defects that occur in this period will be covered under our policy. All our warranties are freely assignable for an unlimited number of times throughout the lifetime of the policy.

What Factors Primarily Affect The Cost Of A New Build Warranty?

There are three main elements that will affect the cost of a warranty:

  • The size and complexity of a development: Our warranties cater for single dwellings through to large residential housing estates or mixed-developments. The size and number of developments will ultimately affect the premium.
  • Credit rating and financial security: One Guarantee will undertake a number of credit checks to determine whether we require any additional financial protection such as Cross Company Guarantees.
  • Developer Rating: We will ask for any previous developer ratings given by other warranty providers as well as any claims history. We will then match this alongside our own rating system, as part of our quotation process.
