Illegal increase of prices:
When they collected the paperwork they did not notify me that they would increase their price. They gave me a sheet stating the amount of paper they had collected. There was no mention of the price, IData have never given any contract or terms and conditions.
I only found out after they sent an invoice with the inflated price. I emailed the owner George Eland as follows: previous agreed commercial arrangement under which services were provided and invoiced at an agreed rate. It was in the form of a previous invoice.
Your invoice was paid in full, thereby discharging the contract in its entirety.
At no point prior to, during, or at completion of the work was any agreement reached for additional or variable pricing.
Accordingly, no contractual basis exists for the subsequent imposition of additional charges.
No valid variation of contract
Any alleged increase in price would amount to a variation of the original agreement.
Under English contract law, a variation requires clear mutual assent.
There is no evidence of any express agreement to a revised price, nor any conduct capable of objectively demonstrating acceptance of a price variation.
Relevant authorities include:
May & Butcher Ltd v R (1934) – contractual terms must be sufficiently certain and agreed
Hillas & Co Ltd v Arcos Ltd (1932) – terms may only be implied where necessary and consistent with the bargain
Williams v Roffey Bros & Nicholls Ltd [1991] – variations require factual agreement and cannot be imposed unilaterally
A unilateral post-completion adjustment of price is not enforceable.
No entitlement to further payment (including quantum meruit)
Any attempt to characterise the claim as a “reasonable charge” or quantum meruit claim is also rejected.
A claim in quantum meruit can only arise where there is no governing agreed price or where services are provided outside a contractual framework.
Where, as here, a previous contract existed, was fully performed, and has been paid, there is no legal basis to reopen the price after discharge of the agreement.
See British Steel Corporation v Cleveland Bridge and Engineering Co Ltd [1984].
Conduct and timing
The alleged additional charge was not disclosed at the time of instruction, during performance, or prior to payment of the agreed invoice.
It was only raised after completion and settlement of the account, which confirms it was not part of any agreed arrangement.
Position
In summary:
A previou contract existed and was performed
The agreed invoice was paid in full
No variation was agreed
No legal basis exists for retrospective charges
The alleged debt is therefore denied in full. He took no notice of the facts or the law.
