Welcome. Recent rain can make the garden look greener, but it does not necessarily mean local water conditions have recovered. Natural Resources Wales (NRW) confirmed on 12 October 2026 that drought status remained in place for parts of Wales, including the north and Upper Severn catchments. NRW said September rainfall and rain in early October had brought some improvement, but not enough to move those catchments into recovery.
That status is based on wider indicators, including river flows, groundwater and environmental impacts. It is not a direct assessment of electrical safety, and it does not automatically mean public water supplies are at risk. But a long spell of hot, dry weather is a useful prompt to check the electrical equipment around homes, farms and business premises.
For properties in Conwy, Denbighshire and Gwynedd, consider outdoor sockets, supplies to sheds and outbuildings, EV charge points, solar equipment and battery storage. These systems are safe when correctly selected, installed and maintained. The purpose of a check is to identify defects early, not to suggest that drought makes a sound installation unsafe.
Why drought status can continue after rain
Drought status describes conditions across catchments over time. A few wet days may improve surface conditions without restoring river flows, groundwater or the wider environment. NRW’s 2026 dry weather updates reported that Wales received 99% of its long-term average rainfall in September, while rainfall over July to September was 62% of average.
The status also does not mean every property faces the same conditions. NRW assesses catchments, not individual buildings. Its July drought update identified catchments including North Gwynedd, South Gwynedd, Dee and Clwyd. Check current local information with NRW and your water supplier. The Welsh Government’s statement on drought explains that environmental drought classifications are separate from water companies’ supply measures.
What prolonged dry weather means for outdoor electrics
Electrical equipment installed outdoors is designed for its intended location and exposure. However, sustained heat, dust and dry vegetation can make routine upkeep more important.
Heat can raise the operating temperature of equipment, especially where ventilation is restricted or equipment is exposed to direct sun. Dust and debris can collect around enclosures, vents and cooling openings. Dry grass, leaves and stored materials can add combustible material near electrical equipment or buildings.
Dry conditions can also affect the ground around buried cables and outbuilding supplies. After a long dry spell, heavy rain can arrive quickly. NRW notes that hard, dry ground can increase rapid runoff and localised flooding risk. This makes it sensible to look for signs of damaged cable routes, disturbed ground or water entering enclosures after weather changes.
Do not open an electrical enclosure or attempt internal repairs. If you see damage, scorch marks, exposed cable, corrosion, water inside an enclosure or signs of overheating, keep clear and arrange a professional inspection.
Check outdoor sockets, outbuildings and cable runs
Walk around the property and look at sockets, switches, junction boxes and cable routes serving gardens, garages, sheds, barns and workshops. Check for visible cracks, loose covers, impact damage, discolouration or signs that the enclosure is no longer secure.
Look at exposed cables for cuts, crushed sections, sagging, loose fixings or damage from gardening, vehicles, animals or storage. Check that plants, dry leaves, hay, cardboard and other combustible materials are not building up around electrical equipment or against walls.
For sheds and outbuildings, make sure equipment remains suitable for the environment and is protected from knocks, dust and moisture. A long dry period does not eliminate water risk. Leaking roofs, faulty gutters, condensation and wind-driven rain can still affect electrical fittings. Once rain returns, check visually for staining, damp patches and water around cable entry points.
Avoid spraying water at electrical equipment or using improvised covers. If an enclosure or cable looks damaged, do not tape it up or continue using it without advice from a qualified electrician.
EV charge points and solar equipment
Give your EV charge point a visual check. Look for damage to the casing, cable or connector, and make sure the cable is stored without kinks or strain. Keep dry vegetation and stored items away from the unit. Follow the equipment instructions for routine care, and report unusual heat, smell, noise or fault warnings to the installer or service provider.
Solar PV systems also need clear surroundings and unobstructed equipment ventilation. Check the inverter display or monitoring app for alerts, but do not remove covers. Dust, leaves and restricted airflow can affect equipment operation. If the inverter reports repeated faults, shows visible damage or appears unusually hot, contact a competent installer.
If you are planning a new system, use a qualified installer for EV charger installation or solar PV installation in North Wales. A site assessment can consider cable routes, outdoor exposure, electrical capacity and how the equipment will be maintained.
Battery storage: ventilation, space and maintenance
Battery storage systems are safe when correctly installed and maintained. Check that the space around the unit remains clear and that ventilation openings are not blocked by boxes, dust, tools, vegetation or stored materials. Follow the system instructions for clearances and keep combustible materials away from the equipment.
Do not move, cover, open or modify a battery or inverter. Do not disable alerts or monitoring. If you notice a persistent warning, unusual smell, visible swelling, leakage, damage or unexpected heat, keep away and follow the system’s emergency instructions. Contact the installer or service provider. In an emergency, call 999.
Installation location and ventilation requirements depend on the system and property. The PAS 63100:2024 specification includes fire-safety requirements for domestic battery storage. Use a competent installer and follow the equipment manufacturer’s guidance. For larger commercial systems, inspection and maintenance should be planned by appropriately skilled personnel.
Seasonal checklist
Use this checklist for a visual review of your home, farm or business premises. Do not remove covers or carry out electrical work.
- Clear dry leaves, vegetation and combustible storage away from buildings and electrical equipment.
- Check visible outdoor sockets, enclosures and cable routes for cracks, damage, loose fittings or signs of overheating.
- Look at cables supplying sheds, garages, barns and workshops. Note any exposed, crushed or sagging sections.
- Keep EV charge point cables tidy and check for visible damage to the unit, lead and connector.
- Check inverter and battery system displays or apps for alerts. Follow the system instructions.
- Keep battery ventilation openings, service access and escape routes clear.
- After heavy rain, look for signs of water entry, damp, staining or disturbed cable routes.
- Record any faults and arrange an inspection rather than guessing at the cause.
When to book a professional inspection
Arrange an inspection if equipment is damaged, repeatedly trips, shows persistent fault alerts, smells unusual, becomes unusually hot or has been affected by water. Also seek advice if an outbuilding supply is old, has been altered several times or has no clear inspection history.
