Free Pipe Insulation Kits Before a Freeze Warning
Eligible UK water customers can order free lagging kits for pipes and taps before stocks run out.
Yes, free pipe insulation kits are available to eligible water-company customers ahead of freezing weather. They cover exposed pipes and outdoor taps to reduce burst risk. Lagging is an insulating sleeve that wraps around pipe.
In its December 2025 notice, Dลตr Cymru Welsh Water described free lagging kits and tap jackets for domestic customers via GetWaterFit. It also listed optional free home-visit installation, according to Welsh Water's cold-snap notice. South East Water says industry-approved lagging and tap protectors are free from its website, according to South East Water's frozen-pipes update.

Who can claim a free kit?
These kits are tied to the company that issues them. A household claims from its own supplier, not from another region. Stock is limited.
That means early requests have more chance before a cold snap.
- Check which company supplies your home
- Use that supplier's request route
- Request before freezing nights arrive
What does the kit cover?
Kits focus on exposed areas. Those spots lose heat fast and split more easily. Pipe lagging wraps straight runs and bends.
Tap jackets cover outdoor taps. Both cut frost contact on vulnerable fittings.
When should you order?
Order before the warning, not during it. Delivery takes time and stocks drop fast. The National Weather Service defines a freeze as surface air at 32ยฐF or below over a widespread area.
It issues a Freeze Warning for below-freezing temperatures over a large area for an extended period, according to National Weather Service glossary.
What if free kits run out?
DIY stores are the backup when free stocks run out. Waterproof foam lagging from a DIY store works as a substitute. The American Red Cross advises adding insulation to attics, basements and crawl spaces.
It also advises pipe sleeves or UL-listed heat tape on exposed pipes, according to American Red Cross Frozen Pipes guide. Measure exposed pipe first, then buy matching sleeve size. Fit it snugly before night frost.
