Energy prices and inflation in Germany 2026: what is really driving prices – heating oil, electricity or gas?

The short answer

Energy prices in October 2026 are 12.2 per cent above the previous year, but not because of electricity or gas: the rise comes from heating oil and motor fuels. Electricity, natural gas and district heating were actually cheaper in September than a year earlier.

Overall inflation fell in October to a preliminary 2.8 per cent, from 3.3 per cent in September. For owners, landlords and businesses this means that the headline “energy is getting more expensive” says nothing about your own heating bill until you know which energy source is in the basement.

How is inflation developing in 2026?

The Federal Statistical Office reports these changes against the same month of the previous year for July to October 2026 (per cent):

	July	August	September	October (preliminary)
Overall index	2.8	2.9	3.3	2.8
Core inflation (excluding food and energy)	2.4	2.4	2.4	2.1
Energy	8.3	10.5	14.9	12.2

The core rate stayed stable over the summer and fell to 2.1 per cent in October. The September spike therefore came from energy. In October the energy rate eased slightly. Destatis publishes the final October figures on 11 November 2026; until then the value is an estimate.

Which energy sources are more expensive, which are cheaper?

The detailed breakdown is available for September 2026 (change against the same month a year earlier):

Energy source	September 2026
Light heating oil	+74.9%
Motor fuels	+37.1%
Household energy overall	+1.2%
District heating	−1.0%
Natural gas (excluding operating costs)	−2.8%
Electricity	−5.5%

The overall energy rate of 14.9 per cent is a weighted average of household energy and motor fuels. The two outliers pull it up while grid-bound energy falls. Destatis notes that the federal government’s measures in force since the start of the year partly dampen prices for electricity, natural gas and district heating. Why heating oil and fuels are rising so sharply is not covered in these releases; I name no cause that I cannot document.

On the economic policy side: the federal government has again cut the energy tax, in particular on motor fuels. The cut took effect on 1 October 2026 and is therefore not yet in the September figures. Whether it lowered the October rate is not shown in the flash estimate.

How much inflation is in energy?

Energy has a weight of 73.9 per mille in the consumer price index. As a rough approximation, not an official decomposition: 14.9 per cent × 7.39 per cent weight is a little over 1.1 percentage points of the September rate of 3.3 per cent. In October, at 12.2 per cent, it is arithmetically around 0.9 percentage points of 2.8 per cent. Excluding energy, September inflation would have been 2.1 per cent (Destatis states this rate explicitly).

That is the economic-policy core: part of inflation arises at the petrol station and in the heating-oil tank, not in the power grid. Relief through the energy tax therefore works mainly where prices are rising. It does not change the fact that a house with an oil boiler carries a price risk that a house with district heating currently does not.

Worked example: what does this mean for three houses?

A pure index calculation with assumed previous-year bills, to show the order of magnitude. The percentages are German averages for September 2026; the individual price depends on tariff, quantity and timing.

House (assumption: previous-year cost)	Index change	Arithmetical effect per year
Oil heating, €2,400 heating-oil bill	+74.9%	about +€1,800
Gas heating, €1,800 gas bill	−2.8%	about −€50
District heating, €2,000 heat bill	−1.0%	about −€20

The gap between the oil house and the district-heating house is of a size that appears in no inflation average. For landlords there is the added point that heating costs can be passed on: tenants carry the risk first, and the consequences are back-payments on service charges and disputes. How the CO₂ price is split between landlord and tenant is covered in the article on the CO₂ price 2027.

What does this mean for the heating decision?

A snapshot is not a heating strategy. Heating oil was almost 75 per cent above the previous year in September, but an energy source that swings that much in a year mainly gives the owner planning uncertainty. That is a reason to review an oil boiler when a decision is due anyway; deadlines and options are covered in the article replacing an oil boiler in 2026. Conversely, the low electricity and gas prices against last year are no free pass. Why electricity is politically steered is explained in the article on household electricity prices, and what a kilowatt hour of heat costs by energy source in the article heat costs per kWh.

What owners and businesses should do now

1. Clarify your own exposure: which energy source heats the building, what was the last annual bill, when does the supply contract expire?
2. Review advance payments. For heating oil at the next fill-up, for gas and district heating at the annual statement, not on the basis of a headline.
3. If you have an oil boiler, calculate the alternatives before the system fails, and clarify funding.
4. Landlords: inform tenants early about advance payments instead of waiting for the back-payment.
5. Wait for the final October figures on 11 November 2026 before drawing conclusions from the estimate.
6. Always read figures at the primary source: the difference between the overall energy rate and individual prices is the difference between fear and a decision.
