Buying used plant machinery without the proper safety certificates is a risk no business should take. The right paperwork protects you legally, keeps your site safe, and proves the machine has been properly maintained. The wrong paperwork, or none at all, can leave you liable for fines, accidents, and equipment that cannot be used.

After forty years moving plant machinery internationally, we know exactly what documentation should come with every machine, whether it is staying in the UK or crossing borders. This guide focuses on the safety certificates required for used plant in the UK, explaining who is responsible for providing them and what to do if something is missing.

Understanding Your Legal Obligations

When you buy or operate plant machinery, you are responsible for making sure it meets current health and safety legislation. The two main regulations that apply are LOLER and PUWER.

LOLER (Lifting Operations and Lifting Equipment Regulations 1998) covers any equipment used for lifting, including telehandlers, cranes, forklifts, and lifting attachments. If a machine can lift loads or people, LOLER applies.

PUWER (Provision and Use of Work Equipment Regulations 1998) covers all work equipment, from excavators and dumpers to rollers and backhoe loaders. PUWER requires equipment to be suitable for use, properly maintained, and inspected by competent people.

Both sets of regulations apply whether you buy new or used. The fact that a machine is second hand does not reduce your legal obligations.

What Happens If You Get It Wrong

Operating plant machinery without the correct safety certificates can result in HSE enforcement action, including improvement notices, prohibition notices, and prosecution. Fines can run into tens of thousands of pounds, and in serious cases, individuals can face imprisonment.

Beyond the legal penalties, there are practical consequences. Your insurance may not cover incidents involving uncertified equipment, your site may fail audits, and employees can refuse to operate machinery they believe is unsafe. Getting the paperwork right from the start is far simpler than dealing with these problems later.

The Essential Certificates and Documents

LOLER Thorough Examination Certificates

If your machine falls under LOLER (anything used for lifting), it must have a valid thorough examination certificate. This is not the same as a service or inspection. A thorough examination must be carried out by a competent person, usually someone with engineering qualifications and specific training in the type of equipment being examined.

For most lifting equipment, thorough examinations are required:

• Every 12 months for standard lifting equipment
• Every 6 months for equipment used to lift people
• After any significant modification or repair
• Before first use if the equipment is new to your business

The certificate will show the examination date, the examiner’s details, any defects found, and the date by which the next examination is due. If defects were identified, there should also be evidence they have been rectified.

When buying a used telehandler or other lifting equipment, always ask for the current LOLER certificate. If the examination is out of date, budget for a new one before the machine goes to work. A thorough examination typically costs between £150 and £400, depending on the complexity of the equipment, and takes a few hours to complete.

PUWER Inspection Records

PUWER does not specify exact inspection frequencies, but it does require regular checks proportionate to the risk. For most construction plant, this means documented pre use checks, routine maintenance, and periodic inspections by a competent person.

Inspection records should show:

• Date of inspection
• Who carried it out
• Any defects or issues found
• What action was taken

These do not need to be formal certificates in the way LOLER examinations are, but they do need to exist and be available. Well maintained machines will have clear service histories and inspection logs. Patchy or missing records suggest either poor maintenance or that the seller has not kept proper track of the equipment.

Service History and Maintenance Records

A complete service history is not legally required in the same way a LOLER certificate is, but it tells you everything about how the machine has been looked after. Regular servicing, prompt repairs, and replacement of wear parts all indicate a machine that is likely to be in good condition.

Ask for:

• Service invoices and receipts
• Records of any major repairs or component replacements
• Details of routine maintenance (oil changes, filter replacements, greasing schedules)
• Any warranty or guarantee documentation

If a seller cannot provide service records, it does not automatically mean the machine is bad, but it does mean you are taking a risk. We always recommend getting an independent inspection if documentation is sparse.

UKCA and CE Marking

UKCA (UK Conformity Assessed) marking replaced CE marking for new equipment sold in Great Britain after January 2023, though CE marks are still valid on equipment already in circulation. These marks show the manufacturer has declared the equipment meets relevant safety, health, and environmental protection standards.

For used plant, the original marking should still be present on the machine. If it has been removed, damaged, or the equipment has been significantly modified, you may need to obtain a Declaration of Conformity from the manufacturer or have the machine reassessed.

Most mainstream manufacturers will provide replacement declarations if you contact them with the serial number. This is particularly important if you plan to sell or hire the equipment later, as buyers will expect conformity documentation.

What Buyers Should Request

When you are looking at a used machine, whether from a dealer or a private seller, here is what you should ask for before committing to buy:

1. Current LOLER thorough examination certificate (if applicable)
2. Service history and maintenance records
3. PUWER inspection logs for at least the past 12 months
4. Declaration of Conformity or evidence of UKCA/CE marking
5. Operator manuals and any relevant technical documentation
6. Details of any modifications or non standard attachments

Do not be embarrassed to ask. Any reputable seller will have this information ready or be able to get it quickly. If someone is reluctant to provide documentation, treat it as a warning sign.

We always supply full paperwork with every machine we sell, because we know buyers need it and because we service and inspect everything properly before it leaves our depot. If you are buying elsewhere and the seller cannot provide what you need, speak to us about arranging an independent inspection or thorough examination.

What Sellers Should Provide

If you are selling plant machinery, being upfront with documentation makes the sale smoother and protects you from future liability. Buyers are increasingly aware of their legal obligations, and a machine with complete paperwork is worth more than one without.

Before listing a machine for sale:

• Arrange a LOLER thorough examination if one is due or expired
• Gather service invoices and maintenance records
• Make copies of inspection logs and defect reports
• Check the UKCA or CE marking is legible and matches the Declaration of Conformity
• Prepare operator manuals and parts lists

If you discover missing documents, it is better to sort it out before advertising. Buyers will either walk away or use missing paperwork to negotiate the price down, and you will still need to deal with it eventually.

Pre Purchase Inspections and Independent Checks

If you are buying a machine without full documentation, or if you simply want peace of mind, an independent pre purchase inspection is a sensible investment. A competent engineer can assess the machine’s condition, identify any safety issues, and advise whether it meets PUWER and LOLER requirements.

Pre purchase inspections typically cost between £200 and £500, depending on the type and size of the equipment. For a high value machine or one with incomplete paperwork, this cost is small compared to the risk of buying something unsafe or unusable.

We can arrange inspections and thorough examinations for customers, or recommend accredited inspection bodies if you prefer to organise it yourself. The key is to use someone genuinely qualified, not just a general mechanic. Look for engineers with LEEA (Lifting Equipment Engineers Association) membership for lifting gear, or those holding relevant NVQs and manufacturer accreditations for other plant.

What to Do If Certificates Are Missing

If you have already bought a machine and discover safety certificates are missing or expired, do not panic, but do not use the equipment until it is sorted.

For missing LOLER certificates: Contact an accredited thorough examination provider. They will inspect the machine, issue a certificate if it passes, or provide a defect report if repairs are needed. Most examination providers can respond within a week, sometimes faster for urgent cases.

For missing service records: Start fresh. Arrange a full service and inspection by a competent engineer, and keep proper records going forward. While you cannot recreate the past, you can demonstrate good practice from the point you took ownership.

For missing UKCA/CE documentation: Contact the manufacturer or their UK distributor with the machine serial number. Most will provide a replacement Declaration of Conformity for a small admin fee. If the manufacturer no longer exists or cannot help, you may need to commission a conformity assessment from a notified body, though this is rare for mainstream equipment.

The important thing is not to ignore the problem. Using uncertified equipment puts you, your employees, and others at risk, and removes your legal protections if something goes wrong.

Keeping Certificates and Records Organised

Once you have the right paperwork, keep it accessible. Store certificates and records either with the machine (in a weatherproof document wallet) or in a central file where operators and managers can find them quickly.

Good practice includes:

• Scanning all documents and keeping digital backups
• Recording certificate expiry dates in a calendar or asset management system
• Attaching a summary label to each machine showing the next examination or service due
• Training your team to check documentation before using hired or newly acquired equipment

We supply all our machines with documentation folders that include the LOLER certificate, service records, and operator manuals. It is a small detail, but it makes a difference when you need to find something quickly or demonstrate compliance during an audit.

Why Proper Documentation Matters

Safety certificates are not red tape. They are evidence that a machine has been properly inspected, serviced, and maintained to safe working standards. For buyers, they provide reassurance and legal protection. For sellers, they make equipment more attractive and easier to sell. For everyone, they reduce risk.

If you are unsure what certificates you need, what to ask sellers, or whether your existing documentation is sufficient, we are always happy to talk it through. We work with customers in the UK and across Europe, and while safety regulations vary by country, the principle remains the same: proper documentation protects everyone.
