Moving to LED is no longer only a financial decision: across Europe it is progressively becoming a legal obligation. The recast Energy Performance of Buildings Directive (EPBD 2024), the ErP regulation, EN ISO 52120 and the commitments of the European Green Deal create a framework in which buildings with inefficient lighting will have to be upgraded — and in which organisations investing in LED and automatic control can draw on funding that covers a meaningful share of the cost. In the UK the directive does not apply, but the direction of travel is identical through the Building Regulations, EPC ratings, the Minimum Energy Efficiency Standards and the mandatory audit schemes. This guide sets out both frameworks and the funding routes available in 2026.
1. The European framework: why LED stops being optional
Directive (EU) 2024/1275 on the energy performance of buildings — the EPBD recast, adopted in May 2024 — sets the most ambitious timetable Europe has ever had for upgrading its building stock. The objective is a zero-emission stock by 2050, with interim milestones that bear directly on lighting. The deadline for transposition into national law ran to May 2026, so the detail now sits in each member state's own legislation.
The four pillars that force LED and automatic control
The EPBD does not apply to buildings in Great Britain. It governs projects in Ireland and elsewhere in the EU, but the UK operates its own framework — and for lighting the practical requirements point the same way.
Approved Document L (and its equivalents in the devolved nations) sets a minimum luminaire efficacy for general lighting in non-domestic work, expressed in luminaire lumens per circuit watt, together with controls requirements and a separate allowance for display lighting. That metric is measured at the luminaire including its control gear, so it is not interchangeable with the lm/W figure on a product data sheet. Confirm the applicable edition and figures with the building control body before fixing a specification.
EPC ratings and the Minimum Energy Efficiency Standards (MEES) are the commercial driver: it is unlawful in England and Wales to continue letting a non-domestic property rated below EPC E, unless a valid exemption is registered. Higher minimum ratings have been consulted on, so check the current trajectory rather than assuming it.
ESOS requires large undertakings to carry out energy assessments on a four-yearly cycle, and SECR requires annual energy and carbon disclosure. Lighting appears in almost every ESOS report as a recommended measure — which makes an ESOS report a ready-made sales lead.
On product compliance, goods placed on the GB market fall under the UK regime, with its own energy labelling and product registration requirements, while Northern Ireland follows the EU rules. The A-to-G rescaled label applies in both. Ask any supplier which market their documentation covers.
2. Compliance timetable: which building is affected and when
This table brings the European deadlines together with the UK milestones and their practical consequences for lighting:
| Building type / obligation | Deadline | Consequence for lighting |
|---|---|---|
| Let non-domestic property, UK (MEES) | EPC E in force now | Below E the property cannot lawfully be let without a registered exemption. An LED upgrade with controls is normally the cheapest route to move a band. |
| New build and refurbishment, UK (Approved Document L) | In force now | Minimum luminaire efficacy in luminaire lumens per circuit watt, plus controls provision. Display lighting is treated separately. |
| ESOS assessments, UK large undertakings | Four-yearly cycle | Lighting appears as a recommended measure in most reports. The assessment provides the baseline evidence an upgrade needs. |
| New public buildings, EU (zero-emission) | From 2028 | Zero-emission standard. Efficient lighting with automatic control and presence detection from the design stage. |
| New private buildings, EU (residential and commercial) | From 2030 | All new buildings zero-emission. Lighting control with automatic dimming designed in from the outset. |
| Major renovation of existing buildings, EU | Already in force | The works must meet the applicable performance requirements, which includes upgrading the lighting installation. |
| Worst-performing non-residential stock, EU | 16% by 2030 / 26% by 2033 | Minimum energy performance standards. Lighting delivers the fastest measurable improvement. |
| Residential stock, EU | National trajectory to 2030 / 2035 | Average primary energy use to fall by at least 16% by 2030 and 20–22% by 2035. Lighting has the lowest cost per kWh avoided. |
| Building automation in non-residential buildings, EU | 2027–2030, phased | Automation system required above the capacity threshold. Lighting must be controllable and metered: specify DALI or KNX. |

3. The rescaled LED energy label: what each class means
Since September 2021 LED luminaires have been rated on a scale from A to G, replacing the previous system of A+++, A++ and A+. Class G can no longer be placed on the market. Class A represents the best technology currently available:
ErP efficacy scale at product level (lm/W of the complete luminaire), in force since September 2021
| Class | Source efficacy (lm/W) | Product efficacy (lm/W) | Description of the typical product |
|---|---|---|---|
| A | ≥ 210 lm/W | > 85 lm/W | The most efficient LED currently available. High-quality drivers, premium chips. |
| B | 168–210 lm/W | 75–85 lm/W | Good-quality LED. Most professional products in the upper-mid range. |
| C | 131–168 lm/W | 60–75 lm/W | Current market standard. The majority of mid-range downlights and panels. |
| D | 100–131 lm/W | 50–60 lm/W | Basic LED. Still on the market but with significant room for improvement. |
| E | 85–100 lm/W | 45–50 lm/W | Low-efficacy LED. Avoidable, given that better classes are available. |
| F | 50–85 lm/W | < 45 lm/W | Class being phased out. Very low-quality LED or dated technology (halogen equivalent). |
| G | < 50 lm/W | Prohibited | Cannot be placed on the market since September 2021. |
← Scroll the table horizontally to see all columns →
- Some suppliers still present products carrying the old energy classification (A+++, A++, A+), which ceased to apply in September 2021.
- That labelling is no longer valid. Any product still showing it should have been moved onto the rescaled label.
- A supplier presenting the old classification is not maintaining its technical documentation — a signal that other evidence may also be missing, such as product registration or a current declaration of conformity.
- For a funding application this is decisive: without a valid class and a registered product you cannot demonstrate the efficiency improvement being claimed.
- Watch the second trap too: the product lm/W on the label is not the luminaire lumens per circuit watt that Approved Document L asks for. Quoting one where the other is required is a common reason for a specification to be rejected at building control.
4. EN ISO 52120 (formerly EN 15232): automation classes and savings
EN ISO 52120-1, which superseded EN 15232, sets out four classes (D to A) of building automation according to how far the building services are controlled, lighting included. It is the technical reference that quantifies the saving a control system delivers:
Building automation classes under EN ISO 52120 and their relative consumption factor for lighting
| Class | Level of automation | Description of the system | Saving vs D | Factor and implication |
|---|---|---|---|---|
| D — Non-efficient | No automatic control | Entirely manual switching, with no dimming and no sensors. | — | Factor 1.51 (reference). 51% more consumption than class C. |
| C — Standard efficiency | Manual switching plus basic time control | Conventional switching with timed switch-off. The minimum tolerable standard. | 0% | Factor 1.00 (normative reference). Baseline level of compliance. |
| B — High efficiency | Automatic presence control plus dimming | Movement and presence detection. Daylight-linked dimming. Automatic switch-off. | 25–35% | Factor 0.80. A 20% reduction against class C. |
| A — High efficiency plus integration | Integrated BMS | Central control over DALI or KNX. Integrated with HVAC and building energy management. | 40–60% | Factor 0.70. A 30% reduction against class C. Expected above the EU capacity threshold. |

The automation class matters for the technical justification of funding: schemes require evidence of a minimum efficiency improvement, and the standard supplies the calculation factors that assessors recognise.
5. Building energy rating and the opportunity for the installer
The building's rating defines the starting point and the scale of the improvement available from LED. This table maps the two against the non-domestic EPC bands used in England and Wales, which are based on a Building Emission Rate modelled against a notional building rather than on absolute kWh/m² thresholds:
| Band | Asset rating | Typical state of the lighting | Opportunity for the LED installer |
|---|---|---|---|
| A+ | Below 0 | Class A automation plus class A or B LED. Sensors and central management. | Net exporter of energy. Lighting is already optimised. |
| A | 0–25 | Class B LED with presence detection and daylight dimming. | Fine tuning through scenes and time profiles. Limited but documentable headroom. |
| B | 26–50 | Class B or C LED plus class B automation. | A further 20–30% on lighting by moving to class A automation. |
| C | 51–75 | Standard class C LED with basic control. | Moving to class B LED plus class B automation can lift the building a band. |
| D | 76–100 | A mix of LED and older technology, with no automatic control. | Strong potential: LED plus automation can recover one to two bands. |
| E | 101–125 | Fluorescent or metal halide, no controls, manual switching. | Top priority. At E the property sits on the MEES threshold — the commercial risk is immediate. |
| F | 126–150 | Dated technology, no control system at all. | Cannot lawfully be let without a registered exemption. Lighting is the first and cheapest measure. |
| G | Over 150 | No insulation, no controls, obsolete equipment. 1970s and 1980s stock. | Urgent upgrade. LED is the lowest-cost intervention with the fastest payback. |
← Scroll the table horizontally to see all columns →
Scotland and Northern Ireland operate their own certificate arrangements, and each EU member state uses its own national scale. The logic holds everywhere: the worse the rating, the greater the share that lighting can recover.
Buildings rated A+ to C already have reasonably efficient installations. The mass of opportunity sits in bands D, E, F and G.
The European Commission puts around 75% of the European building stock in the energy-inefficient category. In the UK, a large share of the commercial stock predates any meaningful lighting controls requirement, with installations never designed for dimming or presence detection.
There is a second, sharper lead source in the UK: any property rated E or below is one revaluation away from being unlettable. The landlord has a commercial deadline, not just an energy bill. The installer who identifies those buildings and arrives first with an LED and controls proposal is selling into a problem the client already has.
6. Funding routes available in 2026
Regulation creates the demand, but financial support is what accelerates the decision to invest. The routes differ sharply between the UK and the EU, so both are set out here:
| Route | Body | Who can use it | Indicative value | Description and eligibility |
|---|---|---|---|---|
| Capital allowances (UK) | HMRC | UK businesses | Up to 100% relief within the AIA limit | General lighting is an integral feature and falls in the special rate pool, but the Annual Investment Allowance can give full relief on qualifying spend up to its limit. The single largest lever for most UK businesses — confirm the treatment with an accountant before finalising the business case. |
| Public Sector Decarbonisation Scheme and Salix funding (UK) | DESNZ / Salix | Public bodies, schools, NHS trusts | Grant funding by phase | Capital grants for decarbonisation and energy efficiency in public buildings. LED with controls is a routine measure within a wider scheme. |
| Business Energy Scotland and devolved SME support | Devolved administrations | SMEs in Scotland, Wales and Northern Ireland | Advice, loans and cashback | Free advice plus loan and grant packages for energy efficiency measures. Terms and availability vary by nation and by year. |
| Energy performance contracting (ESCO) | Energy services companies | Businesses, landlords, public estates | No upfront capital | The ESCO funds the works and is repaid from the measured saving. Common on large lighting estates where capital is the constraint. |
| Certificats d'économies d'énergie (France) | Obligated parties and delegates | Businesses, public bodies, blocks of flats | Premium per operation | White certificate scheme, heavily used for replacing luminaires with LED modules. The claim must be started before works begin. |
| Bundesförderung für effiziente Gebäude (Germany) | BAFA / KfW | Businesses and private owners | 15–35% by measure | Federal programme for efficient buildings, covering lighting and control systems within energy refurbishments. |
| PERTE Eficiencia Energética (Spain) | MITECO / IDAE | Companies and SMEs | 20–40% of the investment | Direct grant for energy efficiency projects, including LED replacement and control systems. Annual calls. |
| National PRR and cohesion-funded calls (EU) | National agencies | Companies, SMEs, public bodies | Set by each call | Recovery and cohesion funding channelled through national programmes. Eligibility of lighting depends on the individual call. |
← Scroll the table horizontally to see all columns →
1. Capital allowances or grant funding → reduces the net cost of the works
2. Preferential finance or an ESCO contract → removes the upfront capital constraint
3. Annual energy saving → 50–70% reduction on the lighting load
Taken together, these levers bring the real net cost well below the gross investment and shorten the payback in proportion. On a let property, add the value of removing a MEES compliance risk, which is what usually gets the decision signed off.
Rates, limits and deadlines depend on the scheme in force, and tax treatment depends on the specific works. Confirm the position before finalising the business case, and never start work on a grant-funded scheme before approval — starting early is the most common reason an application fails.
7. The evidence needed to claim funding
Most routes require a specific set of technical evidence. This checklist covers what is usually asked for:
| Document required | Level of requirement |
|---|---|
| ☐ Pre-works energy survey or audit with metered consumption | Required by most schemes |
| ☐ Before-and-after efficiency statement (kWh/year, kg CO₂/year) | Required to evidence the improvement |
| ☐ Product data sheets showing efficacy in lm/W and the energy class | Required — supplied by Factorled |
| ☐ Luminaire lumens per circuit watt where Approved Document L applies | Required for building control sign-off |
| ☐ Declaration of conformity for all equipment installed | Required — supplied by Factorled |
| ☐ Purchase invoices with product references | Required — traceability of the investment |
| ☐ Quotation or contract with a competent contractor, dated before works start | Required by most schemes |
| ☐ EPC before and after, where the rating is part of the case | Required on MEES-driven and refurbishment schemes |
| ☐ Evidence of the minimum improvement required | Required for assessment and audit |
| ☐ Lighting calculation for the new installation (DIALux or equivalent) | Recommended — strengthens the technical case |
| ☐ Photographs of the installation before and after | Recommended — visual evidence of the works |

📋 The Factorled energy efficiency package: class B luminaire + sensor + DALI driver
The most common reason a lighting funding claim fails is not technical but documentary: the installation is sound, but the file is missing the data sheet with certified lm/W, the declaration of conformity or the product registration.
For every product in our catalogue we hold: data sheets with efficacy in lm/W and the energy class under the applicable ErP regulation, a signed declaration of conformity, LM-79 and LM-80 reports on efficacy and lumen maintenance, and product registration. We supply this documentation with every order, or on request for a funding application.

8. How installers turn regulation into work
The EPBD, MEES and the funding landscape are not simply regulatory news: they are a structural commercial opportunity for contractors who know how to use them.
- Identify the target market
- The most urgent and most profitable buildings are commercial properties rated D to G: offices, hotels, retail parks, healthcare premises and warehouses. In England and Wales the EPC register is public, which makes it possible to build a prospect list of poorly rated let property in a given area.
- Quote with the funding analysis included
- A proposal that carries the saving calculation, the payback and the funding or tax treatment available gives the client everything needed to decide. Most do not know these routes exist: the contractor who does, and who presents them, holds a real competitive advantage.
- Build a network of referrers
- Funded and compliance-driven schemes involve an energy assessor or ESOS lead assessor who produces the survey, and a building services engineer who signs off the improvement. The contractor who keeps those relationships becomes their default for delivery.
The full process, step by step
- Survey the buildingCurrent consumption, installed technology, luminaire count and real hours of use. Without a baseline measurement there is no way to evidence the improvement.
- Propose the LED and controls solutionWith the saving calculation and the rating improvement, applying the EN ISO 52120 factors to quantify what the control system contributes.
- Establish the routes that applyGrant, tax relief or ESCO, with their specific requirements: minimum improvement, deadlines, eligible bodies and required evidence. On grant routes, apply before work starts.
- Obtain the technical documentation from the supplierData sheets with lm/W and energy class, luminaire lumens per circuit watt where Part L applies, declaration of conformity, LM-79 and LM-80 reports, product registration. Factorled supplies this file with every order.
- Build the application with the clientDirectly or alongside an energy assessor. Supporting the application is part of what a specialist contractor offers, not an administrative afterthought.
- Install and hand over the evidence fileInstallation, post-works measurement, before-and-after statement, photographs, invoices and the electrical certification. The complete file is what secures the payment or the claim.
9. Net zero and the 2030 targets: why the pressure will keep rising
The European Green Deal targets climate neutrality by 2050, with a 55% cut in emissions by 2030 against 1990. The UK's own net zero by 2050 commitment is set in law under the Climate Change Act, with carbon budgets setting the interim path. Buildings account for roughly 40% of energy consumption and 36% of CO₂ emissions in the EU, and the picture in the UK is comparable.
What separates this wave of upgrade work from earlier ones is that it does not depend on the energy price or the economic cycle: it follows a legal timetable with dates fixed out to 2050, and in the UK a letting restriction that bites on the landlord directly.
The 2028, 2030 and 2033 milestones are already in the directive, and MEES is already in force. Buildings in the poor bands will have to act, and lighting is always the first measure, because it costs least and produces a measurable result fastest.
For the contractor, that means a predictable pipeline for at least a decade.
Conclusion: regulation makes LED the safest investment of the next ten years
LED already had an unanswerable financial case: payback in 12 to 24 months and savings of 50 to 70%. Regulation now adds a second, equally strong one: a progressive legal obligation that makes the investment unavoidable, and funding and tax relief that cover a meaningful share of the cost.
For the installer, this environment means structurally growing demand for at least ten years, driven by the EPBD across the EU, by MEES and the Building Regulations in the UK, and by net zero commitments on both sides of the Channel. Anyone who positions themselves now as an energy efficiency specialist does not wait for the phone to ring: they go looking for the buildings that have no choice but to change.
