Lionel Mendoza and his wife Lynda, both in their eighties, faced multiple defects shortly after moving into a new-build home in Castle Cary, Somerset, three years ago. Having paid £460,000 for what they expected to be a low-maintenance residence, the couple encountered issues including a persistent roof leak and poorly installed wiring and plumbing behind a kitchen wall. Lionel Mendoza, a former chartered surveyor, attributes these problems to lax workmanship, saying the poor standards appeared to stem from carelessness during construction.

Their experience reflects a wider trend: complaints about defects in new homes reported to the New Homes Ombudsman Service (NHOS) tripled last year, reaching 1,802 compared to 593 the prior year. The NHOS, launched in 2022 as an independent redress scheme, has raised awareness among homebuyers, but industry experts link the surge in complaints to chronic shortages in skilled labour, an ageing workforce, and insufficiently trained apprentices within the construction sector.

Concerns have intensified following the UK government’s recent introduction of the Your First Home scheme, a successor to the Help to Buy programme. Set to provide first-time buyers in England with a 20 percent equity loan backed by the government and a 2.5 percent deposit requirement, the initiative aims to stimulate homeownership but may exacerbate existing industry challenges. Housebuilders are expected to ramp up construction to meet demand, despite longstanding issues with workforce capacity and declining quality standards.

The previous Help to Buy scheme, which operated from 2013 to 2023 and assisted over 387,000 buyers, was itself marred by widespread building defects. Reports revealed that 99 percent of new-build customers experienced problems ranging from minor snags to major structural faults. High-profile investigations uncovered systemic failures within firms such as Persimmon Homes, prompting internal reviews and the introduction of new quality control measures, including retention schemes allowing buyers to withhold a portion of payment until repairs are completed.

Nevertheless, critics, including John Cooper, founder of New Home Quality Control, emphasize that the building industry remains ill-prepared to deliver high-quality homes on an expanded scale. Cooper highlights pervasive issues with brickwork and structural faults, noting that nearly all new homes inspected by his team exhibit multiple defects. Recent inspections have documented hundreds of problems in individual houses, including unstable walls and damaged fittings.

While housebuilders have welcomed the new government programme as a means to stimulate sales amid rising construction costs and planning delays, experts caution that increased supply must be matched with a skilled workforce capable of maintaining standards. Emma Toms, chief executive of the New Homes Quality Board, points to lasting reputational damage from the previous scheme and stresses that addressing quality is essential to restoring confidence. She advocates for mandatory NHOS membership for all developers receiving government support to ensure accountability and customer protection.

Efforts to expand training and apprenticeship programmes have been announced, with Labour pledging £100 million to increase apprenticeships and the National House Building Council investing in training hubs. However, industry representatives warn that additional challenges remain, including attracting sufficient numbers of new entrants and providing employers with the resources to train and retain skilled workers. The Construction Industry Training Board estimates that nearly 48,000 new builders are needed annually to meet housing targets — a figure that appears difficult to achieve given current conditions.

The construction workforce’s demographic profile also raises concerns, with data indicating a significant portion of workers aged 40 and above, underscoring the need for generational renewal. Without addressing these skills shortages and quality issues, experts warn that the new government-backed schemes could result in a continuation or worsening of the problems experienced by homebuyers like the Mendozas.

“The industry can’t produce quality houses right now,” Cooper said. “By increasing the quantity, we risk increasing the number of poor-quality homes.” Lionel Mendoza, reflecting on his own experience, expressed apprehension about the future state of new homes under the new scheme: “I shudder to think.”
