Gas, heating and energy tips for people affected by dementia and carers

Many people with dementia spend a lot of time in their homes. They may be less active, elderly, and may feel the cold more, meaning they use a lot of energy.

The confusion and forgetfulness that dementia typically brings means people with the condition can be more vulnerable to overconsumption and mismanagement of their energy. They might forget to turn lights off or accidentally set the heating too high or too low, and could face higher gas and electricity bills as a result.

It’s also important to prepare for winter months early, before cold weather hits and things become more urgent. Getting your boiler serviced or checked can help avoid breakdowns when you need heating most and ensure your home stays warm and safe.  

Understanding how to use gas efficiently, stay safe, and access support can make a big difference to comfort, wellbeing and peace of mind. There are some helpful tips and services to explore below.

1. Using energy efficiently at home

Small changes can help reduce energy use and keep gas and electricity bills manageable, for example:

• Keep the heat in: Close curtains at dusk and use draught excluders to keep warmth inside
• Set the thermostat: Aim for a comfortable temperature—around 18–21°C in living areas
• Use timers: Setting the heating to come on just before waking up or returning home can help avoid unnecessary use
• Boiler checks: Make sure your boiler is serviced annually to keep it running efficiently and safely. You may be eligible for a free boiler check through the Priority Services Register (more information below).

If remembering to adjust the heating is difficult, consider a smart thermostat or a simple programmable timer that can be set and forgotten.  

2. Help with heating costs: grants and benefits 

There are several schemes that can help with heating costs, subject to eligibility:

• Winter Fuel Payment: A yearly payment for people over state pension age with an income of less than £35,000
• Cold Weather Payment: Extra money if the temperature drops below freezing (zero degrees) for seven consecutive days
• Warm Home Discount: A one-off £150 discount on electricity bills for people on a low income.
• Energy Company Obligation (ECO): May offer free or discounted insulation or boiler upgrades.

You can check eligibility and apply through GOV.UK or by contacting your energy supplier. 

3. Join the Priority Services Register

The Priority Services Register (PSR) is a free support service for people in vulnerable situations, including those living with dementia.

By joining, you can receive:

• Advance notice of planned service disruptions to your gas, water or electricity
• Priority support in emergencies, including alternative heating and cooking arrangements
• Help with meter readings and free annual boiler checks or gas safety checks*
• Accessible communication formats (like large print or braille)

*subject to eligibility and provider.

It’s quick and easy and can offer real peace of mind. You can sign up to the PSR via your Gas Distribution Network’s website which will cover your gas, water and electricity services in one sign-up. Or we can help you through our Dementia Support Line or your Dementia Adviser. Your energy supplier can also help you sign up.

4. Carbon monoxide safety

Carbon monoxide (CO) is a colourless, odourless gas that can be dangerous. Here’s how to stay safe:

• Install a CO alarm near gas appliances and test it regularly.
• Know the signs of CO poisoning such as headaches, dizziness, nausea, breathlessness
• Get appliances checked annually by a Gas Safe registered engineer
• If you suspect a leak, open windows, leave the property, and call the National Gas Emergency Service on 0800 111 999.
