  • Early September warmth (up to 20 °C).

  • Mid-September storms and cooler, wetter conditions.

  5. Commuters allow extra time Wednesday–Friday – roads likely slower.

The UK weather forecast for 7th–13th September 2025 highlights a mixed week of showers, sunshine, and rain across all regions. While Monday and Tuesday offer the driest, brightest conditions, mid-to-late week turns wet and windy, with Thursday standing out as particularly unsettled.

South West homeowners face seven-day waits for urgent repairs as tradie shortages continue to bite Fix Radio analysis shows the South West is among the slowest regions for urgent fixes, while Plymouth records one of the longest city-level waits in the UK The South West records an average 7-day wait for an urgent tradie fix. Plymouth records one of the longest city-level waits in the dataset, at 10 days. Across the 17 cities surveyed, the average wait for an urgent fix is just over 6 days. CITB says the UK construction industry needs to recruit the equivalent of 239,300 extra workers between 2025 and 2029. Analysis from Fix Radio shows that homeowners in the South West are facing an average seven-day wait for an urgent tradesperson fix, placing the region among the slower parts of the UK for repair response times. Based on Fix Radio’s analysis of city-level urgent repair wait-time data from Markel Direct’s Censuswide survey of UK homeowners, the findings point to continued pressure on trades capacity, local demand and labour availability across the region. The national picture remains highly uneven. The East of England records the shortest average wait at three days, followed by the North East on four days, the North West on 4.5 days and London on five. Wales and the South East each average six days, Yorkshire and the Humber sits at 6.5, while the South West, West Midlands, Scotland and Northern Ireland all come in at seven days. At the other end of the scale, the East Midlands records the longest average delay at nine days, leaving a six-day gap between the fastest and slowest regional averages in the dataset. The research also found that 44% of homeowners have already delayed repairs because of the cost of hiring a tradesperson, while city-level data shows waits stretching as high as 10 days in Plymouth for urgent issues. That makes the South West one of the clearest examples of how regional pressure can build when local demand, household repair needs and labour constraints begin to overlap. Set against a construction workforce already under strain, the figures point to a region where availability remains a growing issue for both customers and tradespeople. CITB forecasts that the industry will need to recruit the equivalent of 239,300 extra workers between 2025 and 2029, with the UK construction workforce expected to reach around 2.75 million by 2029. From Fix Radio’s perspective, the findings reflect a wider story around availability, local demand and the challenge of keeping enough skilled people in the pipeline. Waiting times are not only a sign of homeowner frustration. They also show where order books are full, where capacity is tight and where the wider conversation around skills and recruitment is becoming harder to ignore. In the South West, where regional averages are already above the national benchmark and Plymouth stands out as one of the slowest locations in the dataset, that pressure is becoming increasingly visible.
