Key features of Buildmark Choice

Buildmark Choice provides you, your tenants and homeowners with:

Builder warranty & NHBC Guarantee

A builder warranty and NHBC Guarantee for the first two years after completion. During this period, the contractor is responsible for putting right damage to the home(s) or common parts caused by their failure to build to the NHBC Standards. In the event of contractor insolvency in this period, we insure their obligations.

Post completion cover

In years 3 to 10 post-completion, you are covered for damage to specified parts of the home. We will also cover removal, storage, loss of rent and alternative accommodation if the occupier has to move out so that repair work can be done.

Contaminated land cover

Cover if you are served, or are likely to be served, a Statutory Notice about contamination of the land that existed at completion.

Options to extend Buildmark Choice cover

01. Insolvency cover before practical completion

Add insurance cover to protect you if your contractor is unable to complete the build due to insolvency.

02. Professional fees in connection with a claim

Add insurance cover for reasonable professional fees that you incur in connection with a valid claim.

03. Extended period of insurance cover

Extend the insurance period (including for Professional Fees if selected) by a further 2 years, giving 12 years' cover in total.

Machinery Inherent Defects Insurance

Helping you manage development risk

Elements of communal developments can sometimes carry additional risks, which may not currently be covered under the Buildmark Choice warranty and insurance product.

To help bridge this gap NHBC, in conjunction with Arthur J Gallagher (UK) Ltd and HSB Engineering Insurance is able to introduce you to Machinery Inherent Defects Insurance. There are two versions of this product, one that provides a level of cover for mechanical and electrical services, and another for district heating services. HSB provide risk management during the build phase through inspection and design support. Once completed, HSB provide cover for latent defects that damage or cause failure to your M&E system(s).
