MEES Retrofit Push Risks Adding to UK’s Lighting Waste Crisis

5.2 million lightbulbs end up in UK landfill or incineration every year, enough to fill Wembley Stadium’s pitch to waist height. That figure comes from a new Lumenloop report, as reported by Yahoo Finance, and it lands at a difficult moment. The Minimum Energy Efficiency Standards (MEES) will require all rented homes in England and Wales to reach EPC C by 2028. Landlords are scrambling to upgrade lighting, often the cheapest fix, and that risks a surge in discarded bulbs.

Why lighting waste spikes under MEES

MEES compliance pushes landlords to replace old halogen and CFL bulbs with LEDs. A single LED can cut lighting energy use by 80% and last 25 times longer, so the logic is sound. But the transition is messy. Many landlords replace every bulb in a property at once, binning the old ones without a thought for recycling. The Lumenloop report estimates that a typical three-bed semi undergoing a lighting retrofit generates around 12–15 discarded bulbs. Across the 4.6 million private rented homes in England alone, that adds up fast. Councils already struggle with bulb recycling rates below 30%, according to Defra data. The MEES push could push that figure lower.

What it costs a typical household

Lighting accounts for about 11% of a typical home’s electricity bill, or roughly £65 a year for a three-bed semi using 2,500 kWh on lighting. Switching to LEDs can halve that, saving £30–£35 annually. But the upfront cost matters: a pack of ten LED bulbs costs around £15–£25, while a halogen replacement is half that. The payback period is under 12 months, yet the waste problem persists. Bulbs contain metals, glass and, in the case of CFLs, trace mercury. Landfill disposal releases those materials. The Energy Saving Trust recommends using council recycling points or retailer take-back schemes, B&Q and IKEA both run them, but awareness is low.

The catch in the regulations

MEES does not mandate a specific lighting standard, it only requires that at least 75% of fixed light fittings are energy-efficient, meaning LEDs or equivalent. That leaves room for cheap, non-recyclable LED units. The Lumenloop report flags that many budget LEDs are glued together, making component separation impossible. A better approach is to buy fittings with replaceable bulbs, or choose brands that offer recycling programmes. The Green Deal and ECO4 schemes can help with costs for low-income households, but neither covers bulb disposal. The government’s own consultation on MEES, published in March 2024, acknowledged the waste risk but offered no specific remedy.

What this misses is the scale of the opportunity. A well-managed retrofit could reduce lighting waste permanently, LEDs last up to 25 years, so a one-off upgrade cuts future disposal. But only if the old bulbs are recycled now. The Lumenloop report estimates that proper recycling of all 5.2 million bulbs would recover 1,200 tonnes of glass and 40 tonnes of aluminium annually. That’s the equivalent of taking 2,000 cars off the road in embodied energy terms.

Households and landlords should act now. Check your existing bulbs, any CFLs or halogens due for replacement? Take them to a council recycling centre or a retailer with a take-back scheme. For new fittings, choose units with replaceable LEDs or those certified by the Lighting Industry Association’s recycling initiative. The MEES deadline is 2028, but the waste problem is already here. Don’t let a quick fix become a long-term environmental cost.
