IN Brief:
- Some 96% of surveyed businesses reported higher material and product costs during Q2 2026, while 54% reported falling margins.
- Forty-four per cent said six-month forward order books were below expectations and only 14% expected to recruit an apprentice.
- Thirty-five per cent reported more than £10,000 held in retentions, with 15% having more than £100,000 withheld.
SNIPEF has warned that Scotland’s plumbing and heating businesses are losing financial headroom as rising material costs, weaker forward orders, falling margins, retentions, and cautious recruitment place increasing pressure on employers.
The Plumbing and Heating Federation’s State of Trade report for the second quarter of 2026 retains an overall Stable assessment, but the headline masks a deterioration across several of the indicators most relevant to future capacity.
Some 96% of businesses reported higher material and product costs, while 54% said profit margins had fallen. The latter figure has risen from 49% a year earlier, suggesting that cost increases are becoming harder to absorb or recover through customer pricing.
The six-month outlook has also weakened. Forty-four per cent of respondents said forward order books were below expectations, compared with 37% a year earlier, while only 19% reported workloads ahead of expectations.
Current trading remains more resilient. Twenty-nine per cent said activity during the quarter was above expectations and 33% reported trading broadly as expected. The proportion describing conditions as quieter, however, increased from 29% in the first quarter to 38% in Q2.
That combination matters because workload and financial resilience are not the same thing. A contractor can remain busy while becoming less profitable if materials, labour, vehicles, insurance, energy, administration, and finance costs rise faster than the value recoverable under existing contracts.
Plumbing and heating businesses are particularly exposed because skilled labour and compliance capacity cannot be switched on and off quickly. A company that reduces headcount or stops training apprentices during a weaker period may struggle to rebuild that capability when demand returns.
Fiona Hodgson, chief executive of SNIPEF, described a profession that remains active but is under sustained pressure, with weakening orders and falling margins reducing employers’ ability to invest, recruit, and grow.
The apprenticeship figures show how quickly that caution is reaching workforce planning. Only 14% of surveyed employers said they were likely to recruit an apprentice during the next six months, down from 26% a year earlier.
That decline comes while governments continue to place greater emphasis on technical education, apprenticeships, housing delivery, and lower-carbon heating systems. The skills needed to install, maintain, and upgrade those systems ultimately depend on employers being prepared to carry trainees through multi-year programmes.
For a plumbing business, an apprentice is not simply a future labour resource. Employers have to fund wages, supervision, college release, reduced productivity during training, and the commercial risk that an individual may later leave for another company.
Those costs are easier to justify when order books and margins are predictable. They become harder to carry when a business expects weaker work and already has less cash available for investment.
Payment practices are adding to that pressure. Thirty-five per cent of businesses responding to the survey reported having more than £10,000 held in construction retentions, while 15% had more than £100,000 withheld.
Retentions are intended to provide security against defects or incomplete work, but they also remove cash from the businesses delivering projects. A specialist contractor can have substantial sums tied up across several schemes even after labour, tax, materials, and subcontractors associated with those projects have already been paid.
That turns retention into a working-capital issue rather than an accounting detail. Money withheld upstream cannot be used for vehicles, tools, training, wages, stock, or investment, while smaller companies may have to finance the gap through overdrafts or other borrowing.
SNIPEF’s latest findings come as reform of construction payment practices remains under political scrutiny. The federation supports action on cash retentions but has also warned that replacement mechanisms need to be affordable and accessible, rather than simply substituting bonds or guarantees that create a different cost burden for SMEs.
The broader cost picture remains difficult. Product availability is not being presented as the principal constraint; the problem is increasingly the price of securing products and whether contractors can pass enough of that increase through the commercial chain to maintain viable margins.
That issue can be obscured during periods when sites remain active. Supplier insolvency and workforce cuts tend to appear later than the first deterioration in margins, meaning apparently healthy construction output can coexist for some time with weakening specialist businesses underneath it.
The shift towards lower-carbon heating adds another reason to watch capacity closely. Heat pumps, controls, heat networks, and increasingly sophisticated building-services systems require trained installers at the same time as employers are reporting less confidence in recruiting the apprentices needed to replace experienced workers.
For clients and principal contractors, the survey therefore points to more than a subcontractor pricing problem. Commercial pressure that persistently strips working capital and training capacity from specialist businesses can eventually affect tender competition, programme resilience, quality, and the number of competent companies available to take on work.
SNIPEF has retained its Stable classification because the profession is still active and a majority of businesses continue to trade at or above expectations. The concern lies in the direction of the underlying indicators rather than a sudden collapse in workload.
The next quarterly survey will show whether forward orders recover or whether Q2’s weaker pipeline develops into a broader slowdown. With 96% already reporting higher product costs, more than half reporting falling margins, and apprenticeship intentions down sharply, contractors have considerably less room to absorb another deterioration without changing how they recruit, price, or select work.
