Current Business Conditions in the Plumbing and Gas Industry

Purpose

This paper provides an overview of the current operating conditions impacting businesses across the plumbing, gas, mechanical services, HVAC, fire protection, civil and broader construction sectors.

The findings are informed by the Industry Survey Current Business Conditions, undertaken during April and May 2026, which received more than 200 responses from businesses across multiple jurisdictions, regions and business sizes.

The survey captures real-time industry feedback on the impacts of fuel cost escalation, freight volatility, material price increases, supply chain disruption and ongoing cash flow pressures affecting essential trade and construction businesses. This paper is intended to assist government and stakeholders in understanding the current conditions and emerging pressures facing industry.

Executive summary

The survey findings show an industry under immediate and compounding pressure. Businesses consistently reported significant increases in material, fuel, freight and delivery costs, alongside ongoing supply chain disruption, labour shortages and tightening cash flow.

Many respondents indicated that price increases across core plumbing products such as PVC, HDPE, PE and copper have been rapid and difficult to predict. At the same time, businesses are continuing to operate under fixed-price contracts that do not reflect the speed of current cost escalation, forcing many contractors to absorb rising expenses while operating on reduced margins.

As essential service providers, plumbing and gas businesses have limited ability to pause or reduce operations. They continue to maintain critical systems across homes, hospitals, schools, commercial buildings and public infrastructure while managing increasing pressure on project delivery, productivity and business sustainability.

The survey also highlights concerns regarding workforce capacity, apprentice employment and the long-term ability of the industry to support housing, infrastructure and regional service delivery if current market conditions continue.

Survey base and industry profile

The respondent profile is significant, with a large proportion of responses coming from sole traders and small to medium-sized businesses, particularly those employing between 1 to 20 staff. These businesses are often the most vulnerable to rapid increases in fuel, freight and material costs due to limited financial reserves, reduced purchasing leverage with suppliers, and payment arrangements that do not adjust at the same pace as supplier pricing movements.

Many also operate within fixed payment cycles and contractual arrangements that limit their ability to immediately recover escalating costs, placing additional pressure on cash flow, profitability and day-to-day operations.

What the data is showing

The survey consistently identified material price increases, fuel costs, freight and delivery charges, supply chain delays, labour shortages, fixed-price contract pressures and cash flow constraints as the most significant challenges affecting businesses.

A clear trend emerging from the responses is that businesses are being impacted by multiple cost pressures at the same time across essential operational inputs. Plumbing and gas contractors have limited ability to avoid or replace many of these costs, as they must continue to source compliant materials, maintain vehicles and fuel usage, secure labour, and manage freight and logistics in order to deliver regulated work safely, efficiently and in accordance with required standards.

Pressure area	Evidence from survey responses	Business impact
PVC, PE, HDPE and related plastic products	Respondents repeatedly cited increases of around 25% to 50%, with some higher examples. PVC, poly, HDPE and PE products were among the most frequently named items.	Higher job costs, pricing uncertainty, reduced quote validity, increased risk on fixed-price work and short-term stockpiling behaviour.
Fuel and freight	Respondents cited diesel levies, delivery charges, transport surcharges, doubled transport costs and fleet impacts. One respondent reported diesel moving from $1.71 per litre to $2.53 during the period.	Fleet-based essential service businesses face direct cost escalation. Regional and remote operators face amplified impacts due to distance, limited supplier choice and logistics constraints.
Fixed-price contracts	Businesses reported being unable to increase prices on contracted works and absorbing extra expenses on projects already won.	Margins are eroded after contracts are signed. Businesses carry the cost of global volatility without a clear recovery mechanism.
Supply delays	Respondents reported difficulty accessing some materials, delays due to lack of larger PVC pipes and repeated disruptions to project completion.	Delayed works, repeated site visits, lower productivity, higher labour and fuel costs, and pressure on project timelines.
Workforce and apprenticeships	Respondents cited labour shortages, difficulty retaining skilled workers, increasing wage costs and insufficient apprentice support.	Businesses become less willing or able to take on apprentices, which worsens long-term skills shortages and affects future housing and infrastructure capacity.

Material cost escalation

Material cost increases were one of the strongest themes identified in the survey, particularly across PVC and related plastic products, along with copper, brass, steel, hot water units and imported equipment. Businesses reported that price increases have been rapid, widespread and difficult to predict.

Examples provided by respondents included PVC and poly product increases ranging from 30% to 75%, with some products reportedly increasing significantly more. As a result, many businesses have reduced quote validity periods to manage pricing uncertainty, creating additional re-pricing, project uncertainty and pressure across the construction pipeline.

The impact extends beyond new construction projects, with maintenance, emergency repairs and essential public infrastructure also affected by rising material costs and ongoing supply chain disruption.

Fixed-Price Contracts and Cost Volatility

A key issue identified in the survey was the growing gap between rapidly increasing input costs and fixed-price contract arrangements. Many businesses reported absorbing significant additional costs after contracts had already been secured, with limited ability to recover increases through existing agreements.

Respondents highlighted those sudden rises in material, fuel and labour costs, combined with supply delays, are placing substantial financial pressure on trade businesses operating under fixed-price contracts.

As a result, businesses are becoming more cautious in pricing future work, shortening quote validity periods and reassessing their exposure to long-term projects, creating additional pressure across housing, infrastructure and maintenance delivery.

Supply Chain Delays and Productivity

Survey responses highlighted ongoing supply chain disruption and difficulty accessing some materials, resulting in project delays and reduced productivity. Businesses reported increased costs caused by repeat site visits, scheduling disruptions, additional labour and fuel usage, and delays waiting for compliant products to become available.

For regional operators, these challenges are amplified by longer travel distances and fewer supplier options. The survey indicates businesses are not only paying more for materials and freight but are also taking longer to complete the same work.

Cash Flow and Small Business Viability

Cash flow pressure was a major concern raised throughout the survey. Businesses reported absorbing increased costs, operating on reduced margins and managing delays in customer decisions and payments while continuing to meet payroll, tax and superannuation obligations.

Several respondents also raised concerns about the impact of payday super in the current operating environment, particularly while businesses are already facing higher fuel, freight and material costs alongside tightening margins.

The survey highlights that many small and family businesses remain busy and continue delivering work, however rising input costs and delayed payment cycles are creating increasing pressure on liquidity and day-to-day operations.

Workforce, Apprenticeships and Industry Capacity

Labour shortages, apprentice costs, wage pressure and difficulty retaining skilled tradespeople were consistently raised throughout the survey. Businesses reported that rising material, fuel and freight costs are making it harder to employ apprentices, invest in training and expand their workforce.

These pressures have long-term implications for housing, infrastructure and essential service delivery, with concerns that reduced apprentice opportunities today will impact future industry capacity.

Regional and Remote Impact

Regional and remote businesses reported additional pressure due to longer travel distances, freight dependence, limited supplier choice and ongoing workforce shortages. Respondents highlighted that rising fuel and supply chain costs are affecting both project delivery and service reliability in regional areas.

Why This Matters for Government

The survey highlights growing pressure on an industry critical to housing, public health, infrastructure and regional service delivery. Continued cost escalation, supply chain disruption and cash flow pressure risk increasing project costs, reducing workforce capacity and weakening the sustainability of small and medium trade businesses essential to delivering services across Australia.

Conclusion

The survey provides a clear snapshot of the growing pressure facing plumbing, and gas businesses. Businesses are continuing to deliver essential services while managing rapidly rising material, fuel and freight costs, supply delays, labour shortages and tightening cash flow.

The findings highlight increasing pressure on project delivery, small business viability, apprentice employment and regional service capacity. The survey should be viewed as an important indicator of the challenges currently affecting an industry critical to housing, infrastructure and essential community services.
