Should I Turn Off My Water? Energy Saving Tips If You’re Going On Holiday

08 July 2025 | Energy Saving Tips

Preparing your home to be safe and energy-efficient while you’re away can make your much needed break a lot more restful! One common question is whether it’s worth turning off the water supply. Not only can this help prevent potential water damage, but it also offers opportunities to save energy and reduce your bills. Here’s everything you need to know about how to prepare your home for energy savings before you leave.

Why Turn Off Your Water Supply?


Turning off your water supply is a simple but effective way to save money and energy:

When the water is switched off, you won’t need to heat or pump water, which reduces your energy consumption, particularly if your home has a boiler or water heating system that uses energy even when idle.

Also, shutting off the water prevents leaks or burst pipes that could cause costly damage, which can be especially important if you’re away for an extended time.

By preventing water flow while you’re gone, you also avoid running your water heater unnecessarily, saving on energy bills.

How to Find and Use Your Internal Stop Tap


Your internal stop tap (also called a stop valve or stopcock) controls the water supply to your entire home.

It is usually located under the kitchen sink, but it can also be in the kitchen cupboard, downstairs bathroom, garage, utility room, cellar, or under the stairs.

Turn the valve clockwise slowly. It may take a few minutes for all water flow to stop completely. You should be able to listen for the silence to indicate water is no longer flowing.

When you return from your holiday, gently turn the valve anti-clockwise to restore water flow to the house. It may take a few moments for water to flow through all taps normally.

It is always a good idea to check your stop tap on a regular basis to confirm it works properly, as you may need it in an emergency. If it becomes stuck or you’re unsure, contact a professional plumber.

Other Useful Home Energy Tips for Travelling


 

Unplug Electronics and Appliances

Switch off and unplug devices like TVs, computers, chargers and kitchen appliances. Standby power can add up, costing you more in energy bills.

Adjust Your Heating and Hot Water

Set your thermostat to a low temperature or turn off your heating system completely to save on energy bills while you’re away.

Save on Cold Storage Costs

If your fridge or freezer is empty, consider turning it off. Otherwise, keep it running on the lowest energy setting.

Use Timers for Lights

Set timers or smart plugs to turn lamps on and off at intervals. This creates the impression of occupancy and helps prevent burglaries.

By following these simple steps before you leave, you’ll reduce unnecessary energy use, help lower your bills, and protect your property from potential water damage. Enjoy your holiday knowing your home is safe, secure, and energy-efficient. For more tailored advice, or help with energy saving tips, contact RES.
