Compare two equipment lots against the same business task and the same cost scope. A lower bid price may come with missing accessories, uncertain support or more work before use. A higher price may still buy a poor fit.
Start by writing the task in one sentence: the output required, the material or load involved and the date the equipment must be ready. Use the pre-bid decision guide to identify the facts that must be confirmed before either lot can remain under consideration.
Separate requirements from preferences
Some points are conditions of purchase. Others are matters of degree.
A machine that cannot perform the required operation does not become suitable because it scores well for cosmetic condition. An unresolved safety or compatibility question cannot be offset by a cheap price. Mark those points "confirmed", "unresolved" or "fails requirement" before using a score.
HSE's second-hand machinery guidance explains the responsibilities surrounding supply of used machinery in Great Britain. A comparison score is a buying aid, not a compliance assessment.
Only compare eligible candidates on preferences once you have addressed the essential requirements.
An optional weighted comparison
The following fictional weights illustrate a method. Change them to reflect your business; they are not a standard formula.
Score each criterion from 1 to 5, with 5 the strongest supported answer. Multiply the weight by the score, then divide by 5.
| Criterion | Example weight | Lot A score | A weighted points | Lot B score | B weighted points |
|---|---|---|---|---|---|
| Fit beyond minimum requirements | 30 | 4 | 24 | 5 | 30 |
| Strength of condition evidence | 25 | 4 | 20 | 2 | 10 |
| Parts and support availability | 20 | 3 | 12 | 4 | 16 |
| Total cost within budget | 15 | 4 | 12 | 3 | 9 |
| Readiness for the required date | 10 | 3 | 6 | 4 | 8 |
| Total | 100 | 74 | 73 |
The one-point difference is too small to treat as a decisive finding. In this example, Lot B's weak condition evidence deserves attention. If better evidence changes its score from 2 to 4, its total rises to 83. That tells you which enquiry could matter most.
Do not assign a reassuring middle score to a critical unknown. Keep it unresolved until the necessary information is available.
Give every score a reason
Write a short evidence note beside each score. "Parts available" should identify the supplier, relevant component and response date. "Ready quickly" should name the required work and provider availability.
Use the parts and support guide to investigate serviceability. A familiar badge does not guarantee support for the particular revision.
Calculate both lots using the same total purchase cost method. Include the actual sale charges, collection and receiving-site work. Label all estimates. Otherwise one lot can appear cheaper simply because more of its costs remain outside the comparison.
Use the sheet to find the next question
The value of the sheet is that it shows why you prefer one lot and which unknown could change that decision. It does not predict reliability or guarantee savings.
If a UK Auction Group lot has a gap in the evidence, contact UK Auction Group with that specific question. Save the reply with the comparison, then review the relevant score or requirement. Stop comparing if neither candidate meets the business need.
