Valuing Plant and Machinery
How machines are valued, why it is a separate job from the building, and what a chartered engineer is actually checking.
Why separate from the building
A building loses value slowly over decades. A machine can lose half its worth in a few years, or hold value for twenty if it is well kept and still in demand. Averaging them together produces a figure that is wrong for both.
So a lender taking a factory as security wants three numbers: land, building, machinery.
What actually decides a machine's value
- Remaining useful life, not age. A well maintained ten year old machine can have more life left than an abused five year old one.
- Condition and whether it is running. Idle machines deteriorate.
- Make and model. Brands with easy spares and service hold value.
- Whether it is still manufactured. Obsolete machines with no spares fall sharply.
- Whether it can be moved. A machine set into a purpose built foundation is worth less to a buyer who has to extract it.
- The second hand market. Some equipment sells in a week, some sits for a year.
The process
- Full listingMake, model, serial number, year, capacity, with photographs including the nameplate.
- Condition assessmentRunning or idle, maintenance history, visible wear.
- Replacement costWhat the same or an equivalent machine costs today.
- DepreciationBased on actual remaining life, with the working shown rather than a formula applied blindly.
- Market cross checkWhere a resale market exists, use it.
Book value is not market value
Your accounts show a depreciated figure calculated under accounting rules. That figure often bears no relation to what the machine would actually fetch. A machine fully written off in the books can still be worth a great deal, and occasionally the reverse is true.
Imported machinery
Bringing in used machinery normally needs a chartered engineer certificate covering age, condition and value for customs. We issue that alongside the valuation. More on CE certificates.
Questions people ask us
- Can you value machinery from a list without visiting?
No. Condition is most of the value and it cannot be judged from a spreadsheet.
- Our machines are old but working perfectly.
Then they carry real value, and a report based on age alone would understate them. That is exactly why remaining life is assessed on site.
