Halogen bulbs are to be banned in UK homes in a move that will affect nearly a third of all lights sold every year, as Britain follows EU regulations intended to tackle climate change, the Government will say on Wednesday.

Sales of small halogen lamps typically used in spotlights and security lights will be phased out from September this year, following an earlier ban on regular bulbs.

Halogen pins used in small fittings including wall lights, and fluorescent strip lights such as those used in offices will also be banned from sale from 2023 under new legislation which reflects changes being brought in by the European Union.

Steve Baker MP, a trustee of the Global Warming Policy Foundation, said: “Banning these bulbs may or may not be a great step forward. But I do hope that ministers made their own independent assessment of whether it was right for the UK.”

Electrical equipment or fixtures with inbuilt lights that cannot be easily replaced will also be banned from September, which could help stop 100,000 tonnes of electrical waste every year . 

All of the bulbs affected have LED equivalents, though replacements for halogen pins are currently not as bright, and some existing fittings might cause bulbs to flicker and require an electrician to fix.

LED alternatives cost slightly more, but provide savings on electricity bills in the long run. Retailers will be allowed to continue selling their existing stock until it runs out.

The Government will also relabel bulbs to “simplify” their energy efficiency rating, effectively downgrading some from an A or above to a new scale down to a G.

It is hoped that the move will mean LED light bulbs account for 85 per cent of all bulbs sold by 2030, and save 1.26 million tonnes of CO2, the equivalent of half a million cars.

Peter Hunt, the chief policy officer of the Lighting Industry Association said the UK was a leading advocate on energy efficiency.

“The UK was actually pushing harder than most European governments for early phase out of these inefficient lamps,” he said.

Lord Martin Callanan, the minister for climate change, said: “Flicking the off-switch on energy inefficient light bulbs is a simple way that households can save money at the same time as saving the planet.
