We Asked UK Plant Hire Managers About Their Biggest Spare Parts Headaches in 2026 - Here's What They Said
By Vicky Davies, Marketing Manager at HTS Spares
The UK plant hire market is worth an estimated £3.56 billion and continues to grow - but behind the scenes, the managers keeping those fleets on the road are dealing with a mounting list of spare parts headaches.
From supply chain pressure to price inflation and stockroom inefficiency, real-time feedback from our customers tells us that 2026 has already served up a difficult first half for many in the industry.
We've pulled together their feedback, alongside data from UK industry bodies, to give plant hire professionals a clear picture of where the pain points are - and how our team here at HTS Spares can help you overcome them.
The Big Picture: UK Plant Hire Under Pressure
The UK is the largest equipment rental market in Europe, according to the European Rental Association, with rental penetration already sitting at around 75%. That means the industry is busier than ever - but it also means the demand on spare parts, maintenance and fleet uptime has never been higher.
A report by the Construction Plant-hire Association (CPA) published at the end of 2025 warned that “Britain's construction engine is stalling" under the combined strain of skills shortages, weak investment and chronic delivery delays. For plant hire managers, that strain is felt most acutely at the parts counter.
The Top Spare Parts Challenges in 2026
Based on survey data from industry bodies including the Scottish Plant Owners Association (SPOA) and the CPA, as well as broader UK construction market research, here are the challenges coming up most consistently.
1. Parts Availability and Supplier Lead Times
Getting hold of the right part, at the right time, remains the number one frustration for fleet managers.
Global shipping delays and disrupted supply chains (issues that flared up post-pandemic and were compounded by Brexit) have not gone away.
UK construction supply chain research from April 2026 highlights that "rising fuel costs, global shipping delays, and inflation" are still placing the construction supply chain under increased pressure.
Just-in-time procurement has become riskier, with any logistical delay having a knock-on effect on machine availability and site commitments.
HTS Spares solution: With next-day delivery available on thousands of lines and a constantly expanding catalogue, HTS Spares is built for exactly this kind of urgency. Our Holstor smart stock management system also helps you maintain the right parts on-site before a breakdown ever happens.
2. Rising Parts Costs and Margin Squeeze
Parts price inflation is biting hard. Data from the Department for Business and Trade shows that construction material prices for "All Work" rose by 2.0% in the 12 months to January 2026, with some categories seeing much steeper increases. That's on top of ongoing employer National Insurance pressures, fuel cost increases, and the ongoing impact of losing red diesel relief.
SPOA's survey of plant hire businesses ranked rising equipment costs were ranked as the single greatest challenge to business, with one owner estimating that costs had increased by at least 20% since the pandemic.
Squeezed margins mean that every purchasing decision counts. Overpaying for parts (or ordering through a supplier charging above market rate without realising it) erodes profitability quickly.
HTS Spares solution: We supply both genuine OEM and quality aftermarket spare parts, giving you real choice on cost without compromising on quality.Â
3. Machine Downtime and Its True Cost
Unplanned downtime is expensive - far more expensive than most managers account for at the time. A Maintenance Engineering Report based on a survey of 683 UK respondents found that companies average 20 hours of unplanned downtime every week, at an average cost of £100,000.
Even allowing for scale differences, the message for plant hire is clear: a machine sitting idle is a serious financial drain.
The FMB and CIOB State of Trade Survey noted that in the second half of 2025, only 10% of UK construction firms reported no delays at all - with material and equipment delays cited by 31% of respondents as a contributing factor.
Every hour a machine is waiting for a part is an hour it isn't generating revenue.
HTS Spares solution: Browse plant parts by category for fast identification and ordering. Our team is also available to help source hard-to-find components.

4. Managing Diverse Fleets and Mixed Manufacturer Parts
Modern plant hire fleets rarely consist of a single manufacturer's equipment. A typical yard might include JCB telehandlers, Bomag rollers, Wacker Neuson compaction equipment, Kubota mini-excavators and Atlas Copco compressors - all requiring different parts from different supply chains.
Managing multiple supplier relationships, different part-number systems and varying lead times is a significant administrative burden. It also increases the risk of ordering errors, duplicate stock and gaps in availability.
HTS Spares solution: HTS Spares is your trusted single-source supplier, offering parts for all major plant manufacturers through one account. By reducing the number of suppliers you deal with, we help cut administration time and minimise the risk of errors.
5. Stock Control and Over-ordering
Holding too much stock ties up working capital. Too little creates downtime. Getting the balance right is difficult, especially for multi-site operations with unpredictable fleet usage.
Many businesses are still managing parts inventory using spreadsheets or informal tracking - an approach that becomes increasingly unworkable as fleet size grows.
HTS Spares solution: Our Holstor managed inventory system uses barcode scanning and smart stock control to give you real oversight of what you have and what you need, removing guesswork from the storeroom.
6. Sourcing Obsolete or Hard-to-Find Parts
High equipment prices mean older machines are being kept in service well beyond their typical replacement age. Those machines increasingly need parts that are out of production or difficult to source through standard channels. SPOA respondents pointed directly to rising equipment costs as the reason they are extending asset life.
When a part can’t be found quickly, the decision to repair or retire a machine becomes urgent - and can force a costly premature replacement.
HTS Spares solution: HTS Spares holds significant stocks of older and legacy parts, and our experienced team can assist in sourcing components that are difficult to find elsewhere. Contact us directly for hard-to-find enquiries.
7. Parts for Newer and More Complex Equipment
The shift towards hybrid, electric and Stage V-compliant machinery - highlighted in the Barbour ABI UK Plant Hire Market Report as an accelerating trend - creates a new sourcing challenge.
Newer equipment is more complex, less familiar to many maintenance teams and less well served by the aftermarket. As fleets modernise to meet emissions requirements, parts availability for these need to keep pace.
HTS Spares solution: We continually add new product lines to our catalogue to keep up with how fleets are changing. Browse our full plant parts range or get in touch if you need help sourcing components for newer equipment.

What Plant Hire Managers Are Doing About It
The most effective responses we're seeing across the industry share a few common threads:
- Consolidating supplier relationships to reduce admin and improve reliability
- Moving away from purely reactive purchasing towards keeping core consumables and wear parts in stock
- Using managed inventory tools to remove guesswork and free up management time
- Choosing suppliers with multi-brand depth rather than single-manufacturer specialists
The CPA has also called on the government to support the sector through policy changes including fuel duty stability and investment incentives. In the meantime, operational efficiency at the parts management level remains the most immediate lever available to hire businesses.
