Abnormally low tender
A tender is a submission made by a prospective supplier in response to an invitation to tender (ITT). It makes an offer for the supply of goods or services.
A tender which is a potentially abnormally low tender is one which is less than the estimated value by a margin which requires explanation. In particular, any tender that:
- Is more than 15% lower than the adjusted average price; and
- Exceeds the proximity margin, that is more than 1% lower than the lowest qualifying price.
Potentially abnormally low tenders should be excluded unless the tenderer satisfactorily explains the aspects that appear abnormally low.
NB The adjusted average price is the average of all the tender prices provided excluding the highest tender price.
The proximity margin shall be limited to a minimum value of £1,000 and a maximum value of £100,000.
