Winter Pool Care Tips for UK Homeowners
As winter approaches in the UK, it’s essential to properly care for your swimming pool to protect it from damage and make reopening in spring hassle-free. Whether you own a home pool or manage a holiday let, here’s your complete guide to winter pool maintenance.
1. Clean and Balance Your Pool Water
Start by thoroughly cleaning your pool – remove leaves, debris, and insects using a skimmer or pool vacuum. Brush the walls and floor to prevent algae buildup.
Once clean, balance the water chemistry. Ensure your pH, alkalinity, and calcium hardness are within recommended levels. A professional maintenance visit is ideal at this stage to ensure accuracy.
2. Shock the Pool
Before covering your pool, shock it with a chlorine-based or non-chlorine shock treatment. This helps kill any lingering bacteria or organic matter and reduces algae risk during winter.
3. Add Winter Algaecide
Use a winter algaecide designed for long-lasting protection. Pour it around the edge of the pool and allow your filtration system to circulate it for at least 24 hours.
4. Lower the Water Level
Reduce your water level to just below the skimmer. This prevents freeze damage and avoids water getting trapped and expanding in pipework. Be careful not to empty the pool completely, as this can cause structural damage.
5. Drain and Protect Your Equipment
Remove water from your pump, filter, and heater to prevent freezing. Store removable components indoors or protect them with covers. Consider speaking to our team about heating and automation systems that offer freeze protection.
6. Use a Winter Pool Cover
Invest in a high-quality winter cover that fits securely. This keeps debris out, blocks sunlight (reducing algae growth), and acts as a safety measure. Need help choosing the right one? We can supply and fit covers as part of our pool refurbishment service.
7. Check Regularly
Even during the off-season, check your pool every few weeks. Look for signs of sagging covers, debris accumulation, or changes in water levels. Top up or remove water as needed, and re-treat with algaecide if required.
8. Book a Spring Re-Opening Service
When spring arrives, book in a professional re-opening service. We’ll inspect all equipment, balance the water, and ensure everything’s ready for a safe and stress-free season.
Frequently Asked Questions
Can I leave my pool uncovered during winter?
It’s not recommended. A winter cover protects against leaves, dirt, and sunlight, which can all affect water quality and make spring cleaning much harder.
What temperature does pool water start to freeze?
Water begins to freeze at 0°C, but pipes and equipment can be damaged well before this. That’s why draining and insulation are crucial steps.
Is it worth running my pool pump in winter?
In some cases, yes – especially if you have a freeze protection system installed. However, most outdoor UK pools are fully closed down for winter.
Can I still use my hot tub in winter?
Yes! Hot tubs can be enjoyed year-round. Just make sure yours is serviced regularly. See our hot tub maintenance service to keep it in top condition.
