LED Lighting Grants 2026

LED lighting grants in 2025 represent a new wave of financial incentives that enable businesses to upgrade their lighting to modern LED technology. In 2025, the funding landscape is more attractive than ever: in addition to direct investment grants, tax advantages are available that can be combined for maximum benefit.

This comprehensive guide covers which funding programs are currently available, how your business can benefit from an LED retrofit, and what to keep in mind when applying and combining different funding sources. Whether you’re looking at LED retrofit grants, lighting subsidies, or tax incentives for LED — we provide a structured overview for businesses of all sizes, from SMEs to large industrial operators, including municipalities and non-profit organizations.

Overview: How Businesses Benefit from LED Funding

The government supports businesses in multiple ways when switching to LED lighting. Here are the key highlights:
  • Grants of up to 30% for businesses undertaking LED retrofits — in some cases higher through state-level programs or SME bonuses
  • Eligible costs include materials, installation, and planning for the switch to high-efficiency LED lighting
  • Combination with tax benefits possible, e.g. special depreciation under §7c EStG or declining-balance depreciation (degressive AfA)
  • Programs available through KfW (e.g. Loan 263) and the Federal Funding for Efficient Buildings program (BEG)
  • Funding applications must be submitted before work begins — guidance by a qualified partner is strongly recommended
  • Non-profit organizations and municipalities also benefit from dedicated programs

Current Nationwide Funding Programs for LED Retrofits

In 2026, several nationwide funding options are available for businesses switching to LED lighting, from direct grants and low-interest loans to tax incentives. The most important programs are outlined below. They apply to businesses of all sizes, and in some cases also to municipalities and non-profit organizations. We cover BEG grants (via BAFA), the KfW Loan 263, and tax depreciation incentives. (Note: the National Climate Protection Initiative / NKI for municipalities and non-profit organizations is covered separately below.)

BEG Individual Measure: BAFA Grant for LED Lighting

The Federal Funding for Efficient Buildings — Individual Measures (BEG EM) program offers direct grants for the energy-efficient renovation of non-residential buildings. The responsible authority is the Federal Office for Economic Affairs and Export Control (BAFA). The program also covers the retrofit to LED interior lighting.

  • Grant amount: The BAFA grant covers 15% of eligible investment costs for LED lighting systems. Funding generally applies to the complete fixture replacement — including luminaires, light sources, optics/reflectors, necessary ancillary work (installation, commissioning), and the integration of control and regulation systems. Costs for the professional disposal of old lighting can also be included. In addition, technical planning and construction supervision by an energy efficiency expert are eligible for a 50% grant, as the involvement of a certified expert is mandatory.
  • Requirements: The building must be an existing structure (over 5 years old). The new lighting system must meet minimum technical standards — in particular, high luminaire efficiency. Requirements include a system luminous efficacy of at least 120 lm/W (standard lighting systems) up to 140 lm/W (continuous-row lighting systems), and a lumen maintenance rating of L80 at a minimum of 50,000 hours. Only high-quality LED systems qualify. A minimum eligible investment of €300 gross applies (per current guidelines), which is easily met in practice since multiple fixtures are typically replaced.
  • Important: The application must be submitted before any contracts are awarded or work begins. A certified energy efficiency expert (registered on the dena expert list) must support the application and confirm that technical requirements are met.

This BEG funding through BAFA is not limited to commercial businesses, but also extends to municipalities, municipal enterprises, and non-profit organizations. Associations and religious institutions, for example, can apply for LED grants for their buildings. Note that the program covers interior lighting only. Exterior lighting is not covered under BEG (more on this below).

KfW Loan 263: Energy-Efficient Renovation (Non-Residential Buildings)

In addition to grants, KfW (the German state development bank) offers subsidized loans for comprehensive energy renovation projects. The relevant program for LED lighting in commercial buildings is KfW Loan 263 — Federal Funding for Efficient Buildings (BEG) for Non-Residential Buildings. This loan supports the renovation of business and municipal buildings to reach a defined efficiency standard (e.g. Efficient Building 70 or better).

  • Program overview: Loan 263 provides low-interest financing of up to €10 million per project to comprehensively modernize office buildings, production facilities, schools, and similar structures. This typically involves a combination of measures (insulation, new windows, efficient heating systems, etc.), including lighting. If the building achieves a defined efficiency standard following renovation, a portion of the loan is forgiven as a repayment grant. Depending on the level achieved, this grant amounts to between 5% and 25% of the loan amount. The most ambitious projects (e.g. Efficient Building 40 with Sustainability Class) qualify for the highest grants.
  • Terms: Interest rates are significantly below market level (as of early 2025, effective rates from approximately 1% per annum were possible). The combination of a low interest rate and a repayment grant meaningfully reduces the total financial burden. Loan terms can be set over the long term (typically 10 to 20 years), allowing the energy savings from LED and other measures to comfortably offset repayment costs over time. Example: If a business achieves Efficient Building Standard 70 through renovation, approximately 5–10% of the loan amount may be forgiven; for Efficient Building 40 NH (Sustainability Class), the forgiveness rises to around 25%.
  • Requirements: As with the grant option, the building must be over 5 years old. Renovation must be planned and confirmed by a certified energy efficiency expert. Only measures that contribute to achieving the efficiency standard are eligible. A standalone LED retrofit without additional efficiency measures will generally not meet the Efficient Building requirements on its own — Loan 263 is therefore most relevant when LED lighting is part of a broader renovation package. For standalone LED projects, the BAFA grant is typically the more suitable route. Applications for Loan 263 are submitted through the applicant’s own bank (KfW provides the program; the bank processes the application).
  • Important: Applications must be submitted before work begins. Combining Loan 263 with a BAFA grant for the same measure is not permitted.
  • Eligible applicants: Businesses (private and municipal), as well as self-employed individuals, freelancers, municipalities, non-profit organizations, and homeowners’ associations. This program therefore covers a wide range of applicants beyond purely commercial businesses — for example, a municipality renovating a sports hall (including LED lighting) can make use of Loan 263.

 

Summary on BEG funding: Either as a direct grant (BAFA, 15%) for individual measures such as LED retrofits, or as a subsidized loan (KfW 263) for comprehensive renovations. While the BAFA grant is specifically and exclusively designed for interior lighting as a standalone measure, the KfW loan is a more holistic instrument in which lighting is one component of a larger package.

 

Tax Incentive: 30% Immediate Depreciation (Investment Booster 2026)

Alongside traditional funding programs, the German federal government introduced a tax-based investment incentive in 2025 that applies specifically to energy-efficient technologies. Under the so-called Growth Booster Act, businesses can claim accelerated depreciation on new capital assets — LED lighting systems are explicitly included.

  • Core of the regulation: For investments made between 1 July 2025 and 31 December 2027, accelerated depreciation is permitted. Specifically, businesses may write off up to 30% of the investment cost as a profit-reducing depreciation in the year of acquisition. In each of the two following years, up to 30% of the remaining book value can be deducted annually. This declining-balance depreciation ensures that a large portion of costs can be claimed in the early years — delivering a significant liquidity advantage and an immediate reduction in tax burden.
  • Application to LED investments: LED lamps, luminaires, and lighting systems qualify as movable fixed assets and therefore fall under this depreciation rule. This means that if your business purchases new LED lighting in 2025, 30% of the net investment can be recorded as depreciation in the same year — regardless of any grants received. The remaining 70% is then spread over subsequent years (30% of the remaining book value each year until fully depreciated). Example: Investment of €100,000 in an LED retrofit in Q3 2025. Depreciation: €30,000 in 2025; approximately €21,000 in 2026 (30% of €70,000); approximately €14,700 in 2027 (30% of €49,000); and so on.
  • Benefits and combinations: This tax investment booster allows businesses to recover a large portion of costs in the first year — far more effectively than standard straight-line depreciation. Particularly when combined with the 15% BAFA grant, the effect is doubled: the grant immediately reduces the investment cost, while the remaining costs can be written off at 30% in the same year. The net investment is therefore dramatically reduced. Note that grants received reduce the depreciable base (only the business’s own share is eligible for depreciation). Even so, the combined benefit to the business’s liquidity is substantial. This tax depreciation requires no separate application to any funding body — it is simply claimed as part of the annual tax return or financial accounting. Businesses should work with their tax advisor to make the most of this rule for LED investments planned between 2025 and 2027.
  • Strategic relevance: The special depreciation is part of the federal stimulus package to strengthen Germany as a business location. It applies equally to all sectors and business sizes (SMEs and large companies alike), and to all movable capital assets meeting the criteria. Beyond lighting, this includes machinery, IT equipment, vehicles, and more — with electric vehicles benefiting from an even more generous rate (75% special depreciation in the year of acquisition). For LED projects, the rate remains 30%. Nonetheless, this time-limited incentive is designed to bring investment forward. Businesses planning retrofits should therefore act within the stated window rather than deferring, in order to capture the tax advantage.

In summary, businesses in 2025 have the opportunity to combine a 15% grant with a 30% immediate depreciation simultaneously. This substantially reduces the effective investment burden — making LED funding in 2025 more compelling than ever before.

Additional regional funding: Many German federal states and municipalities offer their own funding programs. Some cities have provided flat-rate subsidies, while others have run tiered programs based on system size. It is worth checking the national funding database for current programs available at your business location.

Combining Funding Sources

Not all funding sources can be combined. As a general rule, only one direct public grant can be claimed per measure. Within the BEG program specifically, you must choose between the BAFA grant or the KfW loan for your LED retrofit — double funding is not permitted. Similarly, the Municipal Directive (NKI / federal level) generally cannot be combined with another federal program for the same measure. Federal and state funding can however be combined: Many states permit their own grants to be added on top of federal grants, provided a minimum self-contribution remains (e.g. Bremen adds 10 percentage points to the federal rate). Note that an overall funding ceiling typically applies (e.g. no more than 80–90% of costs may be covered by public funds — the applicant must almost always bear a minimum of 10–20% themselves). Tax depreciation is treated separately from grants and can be used in parallel — it is not a “subsidy” in the traditional sense, but a fiscal benefit. This means, for example, you may receive the 15% grant and still depreciate the remaining 85% using the special accelerated depreciation. What would not be permissible is claiming two grants (e.g. BAFA + NKI) for the same LED fixtures, unless a program is explicitly designed as co-financing.

Investment Grant + Special Tax Depreciation

The combination of a direct grant and special tax depreciation (e.g. under §7 EStG) is both permitted and beneficial. Since these are two different types of instruments — a non-repayable grant on one hand, and a tax advantage on the other — they do not mutually exclude each other. Businesses can receive a grant (e.g. 15% via BEG) and still apply accelerated depreciation to the remaining investment costs. The Growth Program 2025 currently provides for 30% declining-balance depreciation in the first year, which can be used in addition to the LED grant. It is important that the grant is correctly reflected in the tax treatment of the investment (typically by reducing the acquisition cost by the grant amount). Overall, this combination delivers a significantly higher total benefit: the grant immediately reduces the upfront expenditure, while the special depreciation provides rapid tax relief in the year of acquisition. This dual benefit — grant plus tax incentive — is government policy and does not constitute a breach of state aid rules, as tax reliefs are assessed separately from direct subsidies. Businesses should involve their tax advisor to optimize the depreciation, but can in principle claim both benefits simultaneously.

KfW Subsidized Loan + Investment Grant

The key distinction here is whether the same program or different programs are involved. Within the Federal Funding for Efficient Buildings (BEG) framework, there are two access routes: either a direct grant via BAFA, or a subsidized loan with a repayment grant via KfW. These two options cannot be used simultaneously for the same measure — a choice must be made. However, it is entirely possible to use different programs alongside each other, provided they address different costs. For example, a business could take out a KfW loan from an energy efficiency program to cover accompanying measures (such as building insulation) and simultaneously receive a BAFA grant for the LED lighting. As long as the funds are applied to different costs, this is permissible. Combining a KfW loan with a state-level grant is also generally possible. What is essential is that the total funding does not exceed eligible costs and that any applicable subsidy ceilings (funding intensity limits) are respected. When in doubt, check with the relevant funding authority whether a specific combination is permitted. The guiding principle: no two public funding sources for the same euro of investment — and the combination of different sources remains legal and unproblematic.

Combining with State Programs

Many German federal states offer their own funding programs for climate protection and energy-efficient lighting, in addition to federal programs. These state-level grants (such as SME energy efficiency subsidies or municipal investment programs) can often be combined with federal funding. In practice, state grants are frequently awarded in addition to federal grants, subject to a maximum overall funding rate not being exceeded. For example, a business might receive 15% in federal grants and an additional 10% from a state program, totalling 25% of costs. Such combined rates typically remain within EU state aid limits (for energy efficiency projects, grant intensities of 30–50% are generally permissible depending on business size). Public and non-profit bodies may achieve even higher total funding rates (for schools or municipal projects, combinations of up to 60% or even 90% are conceivable where federal and state funding work in tandem).

Important: the prohibition on double funding means the same expenditure cannot be subsidized twice. Some federal programs therefore explicitly exclude combination with certain other programs. A measure cannot simultaneously receive BEG and National Climate Protection Initiative (NKI) funding, for example. municipalities must choose Between the Municipal Directive (NKI) at approximately 25–40%, or the BEG grant at 15%. Similarly, grants from EEG or CHP (KWKG) programs cannot be combined with BEG. State funds, however, typically come from different pots and can be combined, provided the total funding remains within the applicable limits and EU state aid rules (De minimis or AGVO thresholds) are observed. When combining federal and state funding, applicants should carefully review the conditions attached, as funding bodies often require proof that the combined total does not exceed the permitted percentage.

The conclusion: federal and state grants can be used together to increase the overall funding rate, but careful coordination and documentation are essential to ensure all conditions are met. When in doubt, consult the relevant funding authorities directly.

Combining with Contracting or Leasing

Many businesses and municipalities wish to implement their LED projects without committing their own capital. For example through leasing, hire purchase, or light contracting models. The good news is that grants do not have to be foregone when using such financing structures. Direct grants are in principle compatible with leasing or contracting arrangements. In practice, two models exist: either the lessee/client applies for the grant themselves (and passes it on to the lessor to reduce costs), or the contractor/lessor applies for the funding. The latter often requires a joint declaration between the contractor and the end user to confirm that the funded system meets requirements and that the benefit reaches the customer.

It is important that the funding application is submitted before the supply or leasing contract is signed (coordination with the financing partner is strongly advisable). Some programs also require a minimum self-contribution: the Municipal Directive (NKI), for example, requires a minimum 15% own-contribution for externally financed lighting projects, to ensure that the municipality or investor bears a minimum share. For commercial leasing models, such requirements generally do not apply — the grant simply reduces the amount that needs to be financed. Overall, contracting and leasing are compatible with grants, provided transparency exists regarding ownership of the system and the eligibility criteria (e.g. efficiency standards, usage period) are contractually secured.

Businesses can therefore benefit without tying up capital: the monthly leasing or contracting rate is lower thanks to the grant, while the contractor handles planning, installation, and operations. The requirement that no double funding occurs always remains — but a leasing arrangement is not itself a subsidy, merely a financing structure, so the grant can be awarded independently of it.

Funding Conditions (LED Lighting 2026)

Application before work begins
Regardless of the program, the rule is virtually universal: funding applications must be submitted and approved before contracts are awarded or LED fixtures are purchased. If you have already started (e.g. ordered or installed the first fixtures), funding will generally be denied. Plan ahead and wait for the official funding notice before placing any binding orders.
Funding bodies tie grants to minimum technical standards. Familiarize yourself with the technical specifications — such as luminaire efficiency (lm/W), service life, or savings targets. As noted above, BAFA requires specific lumen-per-watt values and an L80 lumen maintenance rating at 50,000 hours. The Municipal Directive requires a minimum CO₂ reduction of 50% for funded hall or street lighting. These criteria must be met through appropriate product selection and planning. If in doubt, engage a qualified specialist to confirm compliance.
For most funding programs (especially BEG), the involvement of a certified energy efficiency expert is mandatory. This expert confirms the correct planning and implementation of the project. Identify a suitable expert early on (via the dena expert database at energie-effizienz-experten.de) to accompany your project. The cost of this expert involvement is often 50% funded (construction supervision). An expert can also help you put together the optimal funding package.
As a general rule, only one direct public grant can be claimed per measure. Within the BEG program, you must choose between the BAFA grant or the KfW loan for the LED retrofit — double funding is excluded. The Municipal Directive (federal level) likewise generally cannot be combined with another federal program for the same measure. Federal and state funding can however be combined: many states permit their grant to be added on top of the federal grant, provided a minimum self-contribution remains. Note that an overall funding ceiling typically applies — applicants must almost always bear a minimum of 10–20% themselves. Tax depreciation is separate from grants and can be used in parallel, as it is not a subsidy in the conventional sense but a fiscal benefit. This means you may receive the 15% grant and still write off the remaining 85% using the special accelerated depreciation. Claiming two grants (e.g. BAFA + NKI) for the same LED fixtures, however, would not be permissible unless a program is explicitly designed for co-financing.
Despite high funding rates, businesses must ensure they can cover upfront costs. For loan programs (KfW) this is self-evident, but even for grants, disbursement typically only occurs after project completion. You will therefore need to advance the investment costs until the grant is reimbursed. Pay attention to your liquidity planning — for larger projects, arranging interim financing through your bank may be advisable. Accelerated depreciation helps on the tax side but does not generate immediate cash inflow, so conservative financial planning is important.
Some funding calls have submission deadlines or annual budget limits. Certain state programs operate on an open-call basis with application windows, or on a first-come, first-served basis until funds are exhausted. Check with the relevant funding body whether the program is continuously open (BAFA and KfW are generally available on a rolling basis) or whether a specific deadline applies. Project duration limits also apply — BEG approvals are valid for 24 months, for example, with extensions possible but requiring a formal request. Plan your LED retrofit so that it can be completed within the funding period.
Ensure your documentation is complete. Typical requirements include: a technical project description (which fixtures are being replaced, by which LEDs, at what wattage and projected savings), supplier quotes and cost estimates, energy savings calculations, and — where required — confirmation from an energy consultant. Also prepare your company documents (e.g. most recent annual accounts if required for a KfW loan, or details confirming SME status). Many funding bodies (BAFA, some state programs) offer online portals and digital forms — use these and read the accompanying guidance notes carefully. Incomplete or incorrect applications lead to follow-up queries and delays.
Thorough preparation can make all the difference. For more complex projects — particularly where multiple funding sources are to be combined — consider engaging a funding consultant. Some providers (e.g. specialist electrical engineering firms or energy consultants) manage the application process for a fee and ensure that deadlines and formal requirements are met. The cost of such advisory services is often itself eligible for funding (e.g. under the BAFA “Energy Consulting for SMEs” module or as part of planning costs). Note that public bodies may need to observe procurement rules when public funding is involved — an expert can advise on this as well.
