Common Mistakes When Selling Plant Machinery in the UK

Selling plant machinery can be straightforward, but relatively small mistakes can lead to lower offers, wasted enquiries, cancelled collections or problems when the machine is finally sold.

Whether you're selling an excavator, telehandler, wheel loader, dumper or other plant machinery, accurate information and good preparation usually make the process much easier.

✔ Give accurate hours and condition
✔ Photograph faults as well as good points
✔ Check serial numbers and ownership records
✔ Include attachments in the description
✔ Agree payment and collection before loading
✔ Compare realistic values, not just asking prices

1. Pricing From Advertised Prices Alone

One of the most common mistakes is assuming that the highest advertised price online represents the true value of a machine.

An asking price is simply what a seller hopes to achieve. It does not tell you:

How long the machine has been advertised
Whether it eventually sold
What price was actually agreed
Whether VAT is included
Whether the machine has been prepared for retail
Whether warranty or dealer support is included

A direct trade value can therefore be different from the price of a prepared machine on a dealer forecourt.

See our plant machinery valuation guide for more information.

2. Not Giving the Exact Make & Model

Descriptions such as "JCB digger" or "CAT excavator" are often not enough.

Buyers generally need the exact model because specifications can vary significantly within the same manufacturer range.

Examples might include:

Exact excavator model
Machine weight class
Telehandler lift height
Loader bucket size
Dozer specification

If you are unsure, photograph the model plate and serial number.

3. Hiding or Understating Faults

Trying to hide mechanical faults can cause more problems than simply describing them accurately.

Tell potential buyers about known issues such as:

Engine faults
Hydraulic leaks
Transmission problems
Travel motor faults
Warning lights
Damaged tracks
Worn tyres
Excessive play in pins and bushes
Cracks or previous welding

A buyer may still be interested in the machine, but unexpected faults discovered during inspection or collection can lead to renegotiation or cancellation.

For machines requiring significant work, see our old, high-hour and non-running machinery page.

4. Poor Photography

Good photographs are one of the easiest ways to make a machine easier to value and sell.

Useful photographs include:

Front of the machine
Rear
Both sides
Cab or operator area
Hour meter
Engine compartment where practical
Tracks or tyres
Boom and working equipment
Identification plate
Attachments
Any known damage

Avoid sending only one distant photograph of the machine sitting in a yard.

5. Photographing Only the Good Bits

Another common mistake is carefully avoiding damaged areas in photographs.

If a track is split, glass is broken or a panel is damaged, photograph it.

Accurate photographs allow a buyer to make a more informed assessment and reduce the chance of disagreement when the machine is collected.

6. Getting the Operating Hours Wrong

Operating hours are an important part of most plant valuations.

If possible, provide a clear photograph of the hour meter rather than estimating.

If the hour meter:

Does not work
Has been replaced
Shows an obviously incorrect figure
Has unknown history

say so clearly.

An uncertain hour reading does not necessarily prevent a sale, but it should not be presented as verified if it is not.

7. Forgetting About the Undercarriage

On tracked machinery, buyers may pay close attention to the undercarriage because replacement components can be expensive.

Useful photographs should show:

Tracks
Sprockets
Rollers
Idlers
Track chains

This is particularly relevant when selling excavators and dozers.

8. Forgetting to Mention Attachments

Buckets and attachments can form an important part of the overall package.

A seller may unintentionally undervalue the machine by simply saying "three buckets included" without explaining what they are.

List attachments such as:

Digging buckets
Grading buckets
Hydraulic breakers
Quick hitches
Forks
Jibs
Grabs
Rippers
Augers

Photograph them separately if possible.

9. Not Checking the Serial or PIN Number

The machine identification plate can help confirm the exact model and specification.

Before advertising the machine, check that the number is readable and that it matches any paperwork you have.

A missing, damaged or inconsistent identification plate may cause buyers to ask additional questions.

10. Losing Ownership & Purchase Records

Plant machinery does not always have the same registration paperwork as a road vehicle, so purchase invoices and asset records can be particularly useful.

Useful documents may include:

Original purchase invoice
Previous bill of sale
Company asset record
Finance documents
Service history
Manufacturer information

See our documents needed to sell plant machinery guide.

11. Ignoring Outstanding Finance

If finance is still outstanding on the machine, deal with it before the sale reaches collection stage.

Useful information includes:

Finance company
Agreement details
Current settlement figure
Settlement procedure

Unexpected finance discovered late in the transaction can delay or stop a sale.

12. Cleaning Too Much – or Not at All

Plant machinery does not need to look like a showroom vehicle, but basic presentation helps.

Removing excessive mud and rubbish can make it easier to inspect:

Hydraulic components
Tyres and tracks
Body panels
Identification plates
Leaks
Attachments

However, expensive cosmetic preparation is not always worthwhile on older working machinery.

13. Repairing Everything Before Getting a Valuation

Another mistake can be spending heavily on repairs before establishing whether they will increase the sale price by the same amount.

For example, replacing:

Tracks
Tyres
Hydraulic rams
Glass
Body panels

may improve value, but the cost of the repair does not automatically translate into an equal increase in selling price.

It can be worth obtaining a valuation in the machine's current condition before committing to expensive work.

14. Not Describing How the Machine Was Used

Previous use can provide useful context.

For example, a machine may have worked in:

Plant hire
Groundworks
Quarrying
Demolition
Agriculture
Utilities
Landscaping
Recycling

Two machines with identical hours can have experienced very different working conditions.

15. Ignoring Service History

Service records may help demonstrate how a machine has been maintained.

Useful information includes:

Routine servicing
Engine work
Hydraulic repairs
Track replacement
Transmission repairs
Major component replacement

Even partial service history can be useful.

16. Not Checking What Is Actually Included in the Sale

Before agreeing a price, make sure both parties understand what is included.

For example:

Which buckets are included?
Is the hydraulic breaker included?
Are spare wheels or tracks included?
Is a trailer included?
Are forks or jibs included?

List important equipment on the sales invoice.

17. Poor Payment Security

Do not release valuable machinery purely because somebody shows you a payment screenshot.

Before collection:

Check cleared funds in your own bank account
Confirm the agreed amount
Confirm who is collecting the machine
Keep a written invoice or sale record
Record the buyer's details

If the machine is being collected by a third-party transporter, make sure you know who has authorised them.

18. Arranging Collection Before Everything Is Agreed

Heavy machinery collection can involve considerable planning.

Before transport arrives, confirm:

Final purchase price
Payment status
Collection date
Machine location
Machine weight and dimensions
Whether it starts and drives
Whether loading assistance is available
Whether attachments are included

19. Forgetting About Access for the Transporter

A low loader cannot always reach the same places as the machine itself.

Tell the buyer if the machine is located:

Down a narrow farm lane
On a construction site
Behind locked gates
On soft ground
Inside a building
In a yard with limited turning space

Collection problems can quickly become expensive if the wrong transport is sent.

20. Not Being Clear That a Machine Is Non-Running

If the machine cannot move under its own power, say so before transport is booked.

The collector may need:

A winch
A crane
Additional loading equipment
A different trailer

Never assume a transporter can simply load a dead machine without preparation.

21. Advertising Everywhere at Once Without Managing Enquiries

Listing a machine across several marketplaces can generate enquiries, but it can also create confusion if the information or price differs between adverts.

Keep the following consistent:

Price
Hours
Condition
Attachments
Location
Availability

Remove adverts promptly once the machine has sold.

22. Assuming Export Buyers Always Pay More

Export demand can help support values for some machines, particularly older commercial equipment, but an overseas buyer does not automatically mean a higher price.

Transport, shipping, import duties and destination-country demand all affect what an export buyer can pay.

See our selling plant machinery to export buyers guide.

23. Choosing the Wrong Sale Route

Different machines suit different routes to market.

Options can include:

Private sale
Trade buyer
Auction
Export buyer
Direct fleet disposal

See our auction vs direct sale guide and dealer vs private sale guide before deciding.

24. Waiting Too Long to Sell an Unused Machine

Machinery that is no longer required can still cost money while sitting unused.

Potential costs include:

Storage
Insurance
Finance payments
Deterioration
Battery problems
Tyre deterioration
Corrosion

If a machine is genuinely surplus to requirements, it can be worth establishing its value rather than leaving it unused indefinitely.

25. Not Getting a Valuation Before Advertising

Getting an approximate value before advertising can help prevent the machine being priced far above or below the market.

A valuation also gives you something to compare against:

Private-sale asking prices
Auction estimates
Trade offers
Export enquiries

See our truck and plant machinery valuation guide for more information.
