Executive Summary
The National Electricity Tariff is designed to be fair for everyone. However, fairness also means recognising that some households cannot reduce their electricity consumption because they rely on essential medical equipment or have genuine medical needs that require additional heating.
The Medical Allowance ensures these households are never financially penalised for electricity they cannot avoid using. Rather than creating separate tariffs or complex exemptions, the policy simply adjusts the household’s monthly peak allowance to account for medically essential electricity use.
This keeps everyone within the same simple tariff structure while protecting the most vulnerable.
The Problem
Many households rely on electricity to keep life-saving or medically essential equipment operating.
Examples include:
- Home dialysis machines
- Oxygen concentrators
- Ventilators
- CPAP machines for severe sleep apnoea
- Feeding pumps
- Nebulisers used frequently
- Pressure-relief mattresses
- Stairlifts and essential mobility charging equipment
- Powered wheelchairs and mobility scooters where regular charging is medically necessary
- Refrigeration for temperature-sensitive medication
- Specialist communication equipment for severely disabled individuals
These households often have little or no ability to reduce electricity consumption.
Under many tariff structures, unavoidable high usage can result in significantly higher bills.
That creates an unfair situation where people are effectively paying more because of a medical condition.
Policy Objectives
The Medical Allowance will:
- Protect households with unavoidable medical electricity use.
- Ensure no one is financially disadvantaged because of essential medical equipment.
- Keep the tariff simple and easy to understand.
- Maintain incentives to reduce unnecessary electricity consumption.
- Avoid creating separate complex social tariffs.
How the Medical Allowance Works
Each household receives a monthly peak electricity allowance before higher tariff bands apply.
Where medically essential equipment consumes electricity, the household’s peak allowance will begin each month with a negative balance equal to the expected electricity consumption of that equipment.
This effectively increases the household’s monthly allowance.
Example
A household requires a home dialysis machine.
Estimated monthly electricity use:
50 kWh
Instead of beginning the month at:
0 kWh
the household begins at:
-50 kWh
The first 50 kWh of medically essential electricity therefore does not count towards the household’s peak allowance.
If the normal allowance was 400 kWh, the household effectively receives 450 kWh before moving into the higher tariff bands.
The household still benefits from reducing unnecessary electricity use because all other consumption counts normally.
Heating Allowances for Medical Needs
Some medical conditions require homes to be maintained at higher temperatures.
Examples may include:
- Elderly people with serious health conditions
- People undergoing cancer treatment
- Individuals with severe respiratory illnesses
- Certain neurological conditions
- Some disabled people with limited mobility
Where a medical professional confirms an increased heating requirement, an additional electricity allowance may also be provided.
This recognises that higher electricity consumption is medically necessary rather than discretionary.
Keeping the System Fair
The Medical Allowance is not intended to remove all incentives to reduce electricity use.
Instead, it only excludes electricity that cannot reasonably be avoided.
Households still benefit from:
- improving insulation
- replacing inefficient appliances
- shifting electricity use overnight
- reducing unnecessary consumption
Everyone therefore remains part of the same national demand management system.
Protecting Vulnerable Households
The National Electricity Tariff already provides significant benefits for vulnerable households.
These include:
- A single national tariff with no postcode lottery.
- Predictable monthly bills.
- No standing charges.
- Cheap overnight electricity at 7.5p/kWh.
- Lower standard electricity prices at 15p/kWh.
- No penalty for using electricity overnight.
Many vulnerable households already consume large amounts of electricity overnight through:
- Heat pumps
- Storage heaters
- Electric heating
- Hot water cylinders
- Mobility equipment charging
Because overnight electricity is charged separately, this consumption is both cheaper and does not reduce the household’s monthly peak allowance.
Housing Policy Should Solve Housing Problems
High electricity bills are often caused by poor-quality housing rather than the electricity market itself.
Cold, damp and poorly insulated homes require significantly more energy regardless of the tariff.
The National Electricity Tariff should not become a substitute for housing policy.
Instead, separate government policies should:
- Improve insulation standards.
- Upgrade social housing.
- Remove damp and mould.
- Improve building efficiency.
- Support low-income homeowners with energy efficiency improvements.
Addressing these issues directly is a more effective and permanent solution than continually adding complexity to electricity pricing.
Benefits
This approach:
- Protects households with genuine medical needs.
- Keeps the tariff simple.
- Avoids complicated social tariff structures.
- Maintains incentives to reduce unnecessary demand.
- Prevents vulnerable households being pushed into higher tariff bands through unavoidable electricity use.
- Supports electric heating where it is medically necessary.
- Works alongside wider health, housing and social care policies rather than replacing them.
Frequently Asked Questions
Who decides who qualifies?
Eligibility should be based on nationally defined medical criteria supported by a healthcare professional. Electricity suppliers would administer the allowance using a standard national process to ensure consistency across the UK.
Could people abuse the system?
The allowance would only apply to recognised medical conditions and approved equipment, supported by appropriate medical evidence. Regular reviews could ensure that the allowance remains appropriate where circumstances change.
Why not create a separate medical tariff?
A separate tariff would add complexity and create another category of electricity pricing. Adjusting the monthly peak allowance achieves the same outcome while keeping every household on the same simple national tariff.
Does this remove the incentive to save energy?
No. Only medically essential electricity is excluded from the peak allowance. Households still benefit from reducing all other electricity use and from shifting flexible demand to the cheaper overnight period.
Conclusion
The Medical Allowance is a simple adjustment that makes the National Electricity Tariff fairer without making it more complicated. By recognising unavoidable medical electricity use, it protects those who need support most while preserving the core principles of the policy: a simple national tariff, predictable bills, and incentives to reduce peak demand. Combined with wider improvements to housing, health and social care, it ensures vulnerable households receive targeted support without burdening the electricity market with broader social policy objectives.
