Heat Pump Funding in Hannover: KfW 458, proKlima and How You Apply Yourself

Heat pump funding in Hannover has two building blocks: the federal KfW 458 grant with a 30 % base rate and bonuses of up to 70 % (up to 80 % in the lowest income band) and, in Hannover, Hemmingen, Laatzen, Langenhagen, Ronnenberg and Seelze, the regional proKlima grant, whose 2027 programme starts on 1 January 2027. You submit the KfW application yourself in the «Meine KfW» customer portal. It is based on a concrete quote for your new heating system, and that quote is what you get from us. This article explains how much grant is realistic, what changes from February 2027 and in which order to proceed so that you don’t lose the funding.

Heat pump funding in Hannover: the key facts

KfW 458: how the grant for your heat pump is made up

The most important building block is the federal funding for efficient buildings (BEG), which private individuals receive through KfW. According to the KfW programme page 458 and the fact sheet (as of 09/2026), the current terms have applied since 21 July 2026. The grant covers the installation of an electric heat pump in an existing residential building, provided it meets the technical minimum requirements of the funding guideline.

Base rate and climate speed bonus

Every applicant receives a 30 % base rate on the eligible costs, even if you rent the house out. If you live in the house yourself, the 16 % climate speed bonus is added. The condition is that you replace a working oil, coal, gas floor or night-storage heater, whatever its age, or a gas or biomass boiler that has been in operation for at least 20 years at the time of application. The old system must be properly removed and disposed of.

Income bonus: heat pump grant of up to 70 percent

Owner-occupiers with a lower income also receive an income bonus. It depends on the taxable annual household income: up to €30,000 gives 40 %, up to €40,000 gives 30 % and up to €50,000 gives 10 %. If a child under 18 with child-benefit entitlement lives in the household, these limits rise once by €10,000. All components together are normally capped at a 70 % grant. Only with a household income of up to €30,000 (with a child up to €40,000) is the ceiling 80 %.

Eligible costs: up to €28,000 in a single-family home

The percentage applies to the total eligible costs, which are capped: €28,000 for the first dwelling, €15,000 each for the second to sixth and €8,000 each from the seventh. Besides the unit and its installation, preparatory and restoration work as well as specialist planning and construction supervision are also funded. Financing, operating and maintenance costs are not eligible. What a heat pump costs in your home depends mainly on the heating load, the heat source, the condition of the radiators and the work required at the installation site. We clarify these points during the on-site planning before we give you a quote.

Worked example: what the funding means for your heat pump

The following example shows the maximum possible grants for a single-family home whose eligible costs reach or exceed the €28,000 cap. If your costs are lower, use your actual amount.

Heat pump funding by case

Heat pump funding in Hannover is therefore most attractive for owner-occupiers replacing an old oil or gas boiler. Please note: there is no legal entitlement to the grant. KfW funds within the available budget and checks each application individually.

Why planning early pays off: bonus and cap will fall

According to the fact sheet, the climate speed bonus falls for the first time on 1 February 2027 and then every six months (1 February and 1 August) by 4 percentage points. Applications from 1 August 2028 no longer receive it. Also from 1 February 2027, the cap for the first dwelling falls by €750 every six months. What counts is the date of your application, not the installation date.

What this means: an owner-occupier who replaces an oil boiler and applies from 1 February 2027 gets 30 % + 12 % = 42 % of at most €27,250, i.e. up to €11,445 instead of €12,880. In addition, KfW has announced a value-added bonus for the first quarter of 2027. The base rate could then fall, for example to 15 %, for heat pumps not made in the EU or associated markets. The details have not yet been published, so we do not include it here.

Regional heat pump funding in Hannover: proKlima

On top of KfW, six towns in the region offer a grant from the proKlima climate fund, which enercity funds together with the towns. The funding area covers Hannover, Hemmingen, Laatzen, Langenhagen, Ronnenberg and Seelze.

What proKlima paid for heat pumps in 2026

Under the proKlima 2026 guideline, existing one- and two-family houses received up to 5 % of eligible costs, at most €1,500 for an air-to-water heat pump and €2,500 for a ground-source heat pump. Bonuses were added, for example €2,000 for the heat source and €1,000 for recording consumption data. Conditions included a design flow temperature of no more than 55 °C, hydraulic balancing, a natural refrigerant for air-to-water units and electricity from renewable sources. According to proKlima, its grant can be combined with federal funding up to 60 % of eligible costs.

2026 funding year ended: what applies now

The proKlima 2026 programme ended on 31 October 2026, and you cannot apply at the moment. According to proKlima, the 2027 programme starts on 1 January 2027. The 2027 terms have not been published yet, so the amounts above may change. If you want to place your order earlier, you can request an early project start from proKlima and submit the funding application in January. As always with proKlima: only while funds last.

Your heat pump in Hannover and the district heating bylaw

A district heating bylaw (Fernwärmesatzung) applies in parts of the city of Hannover. Inside the bylaw area, a major change or renewal of the heating system can trigger an obligation to connect to district heating. According to the city’s FAQ, it only applies from a total rated heat output of 25 kW, and detached one- and two-family houses of normal size are usually not affected.

Important for you: according to the city’s FAQ, heat pumps count as emission-free systems. If your house is in the bylaw area, a simple description of the system concept, submitted online to the city, is usually enough for an exemption. The enercity map of the bylaw area shows whether your address is affected. Ideally check this before you apply for funding.

Heat pump funding in Lower Saxony and around Hannover

We have not found a general Lower Saxony state grant for heat pumps in private single-family homes on the official websites (as of November 2026). We are not aware of a separate heat pump programme of the Hannover Region either. If you live in Burgdorf, Lehrte, Barsinghausen, Springe or another town outside the proKlima area, KfW 458 is therefore usually the only source of grants. For interim financing, KfW also offers a supplementary loan.

How to apply for KfW funding: step by step

Heat pump funding in Hannover follows the same order as everywhere in Germany, and that order decides whether you get the money. If you sign the order without a suitable contract clause or start work before applying, you lose the grant.

Our quote is the basis for your application

Important first: you submit the application yourself. We do not file KfW applications and we do not help fill them in. What we provide is the quote for your heat pump. It is the prerequisite for everything else: without a concrete quote you can neither state the eligible costs nor sign a contract, and therefore cannot apply.

1. Consultation and quote: we check the house, heating load and installation site and prepare your quote.
2. Confirmation for the application (BzA): according to KfW, it is issued by an energy-efficiency expert from the federal expert list (dena) or by a specialist contractor. It contains the planned heating system, the eligible costs and confirmation of the technical minimum requirements. Clarify before applying who will issue the BzA for you.
3. Contract with a condition: the supply or service contract must contain a condition precedent or a condition subsequent linked to the KfW approval, plus the expected implementation date. Adding it later is not allowed.
4. Application in «Meine KfW»: you register in the customer portal yourself and upload the BzA and the contract. The person who registers must be the applicant.
5. Approval and installation: installation can start after approval. The project must be completed within 36 months.
6. Proof and payment: after installation, the confirmation after completion (BnD) is issued. You upload it with the invoices in «Meine KfW», and KfW then pays out the grant.

In the proKlima area, the proKlima application is added. Under the 2026 rules this was possible even after placing the order, if federal funding had been applied for and the proKlima application arrived within four weeks of the KfW decision. Check with proKlima before applying whether this remains the case in 2027.

Heat pump and solar: what is funded and what is not

KfW 458 funds the heating, not the solar system. There is no federal grant for solar panels and battery storage, but there is 0 % VAT since 1 January 2023 and the KfW 270 loan. The heat pump itself is invoiced with 19 % VAT. How to combine both sensibly and how much solar power your heat pump can really use in winter is explained in our guide combining a heat pump with solar. All grants for solar systems in the region are listed under solar funding in Hannover, and the nationwide overview under solar subsidies in Germany.

New heat pumps with more than 4.2 kW connected load are also controllable consumption devices under § 14a EnWG. In return you pay reduced grid fees. The heat pump is registered with the local grid operator, in Hannover enercity Netz or Avacon depending on the area.

Your heat pump in Hannover from PVPro Solar

We install heat pumps for private homes in Hannover and the surrounding region. Installation and electrical connection are carried out by our own technicians, without changing subcontractors. You receive a written fixed-price quote that shows the costs clearly, and that quote is the basis for your KfW application. If you already have a solar system or are planning one, we design the heat pump so that it can use solar surplus, for example via SG Ready or an energy management system.

Because we work in the Hannover region, we know the proKlima area, the district heating bylaw and the local grid operators.

Conclusion: secure the funding, keep the order

If you replace an old oil or gas boiler with a heat pump in your owner-occupied single-family home in Hannover and apply by the end of January 2027, a grant of 46 to 80 % of at most €28,000 eligible costs is possible depending on income. In the proKlima area, a regional grant is expected to be added from 2027. After that, the bonus and the cap fall every six months. Start with a concrete quote, clarify the BzA, only sign a contract with a funding condition and submit your application in «Meine KfW» before work begins.
