If you alter the terms of the contract, your Bond protection may be lost.
If you alter the terms of the contract, your Bond protection may be lost. Hackney Empire agreed with a Contractor that it had employed to enter into a “side agreement” in respect of making three stage payments to the Contractor to cover, in part, a claim for loss and expense that the Contractor had submitted while the Contractor, in accordance with the contract, provided further particulars of its loss and expense claim, whilst at the same time attempted to progress regularly and diligently to meet a newly agreed completion date, at which time the final stage payment would be released. However, and despite this “side agreement”, the Contractor fell into administration.
Hackney Empire had a Performance Bond in place with Aviva, and, because of the failure of the Contractor as outlined above, called upon that Bond. However, Aviva refused to honour the Bond because it said that the “side agreement” that Hackney Empire had reached with its Contractor, was a material variation of the contract between Hackney Empire and its Contractor, and that meant that the Bond was invalidated.
The matter was referred to the Technology and Construction Court in London, and the Court found that the Bond was still valid and Aviva was required to honour the Bond as the “side agreement” had not in fact varied the terms of the contract between Hackney Empire and its Contractor.
However, if the “side agreement” had varied the terms of the contract, the matter may well have been different. Therefore the risk is that a “side agreement” could invalidate a Performance Bond, or it could be that Bond providers may amend the wording of Bonds to “define” what type of “side agreement” in respect of the operative contract would have the effect of invalidating the Bond.
In the present economic climate, “side agreements” are becoming more and more common. Therefore, if you are tempted to enter into some form of “side agreement”, particularly where you have a Performance Bond in place, proceed with extreme caution, as you may repent at leisure over the action you took in haste.
Therefore, if you are considering entering into a “side agreement” and are unsure if this would have an impact on a live Performance Bond, then you need to contact us (i.e. Melbury Construction Consultants Ltd) to find out how this may affect your contractual and/or legal rights and/or obligations.
