Big changes are coming to lighting efficiency rules in England, and now is a good time to plan around them.
The new 2026 edition of Approved Document L (Part L) raises the minimum efficiency for fixed internal lighting in dwellings from 75 to 105 light source lumens per circuit-watt. It takes effect on 24 March 2027.
In plain terms: older, less efficient lamp types won't make the grade, while modern quality LEDs do. If you are planning a renovation, extension, kitchen refit or rewiring in the next couple of years, specifying the right fittings now will save rework later.
The good news is that most well-made modern LED downlights already exceed the new threshold, and quality fittings bring extra benefits: changeable bezels to suit your decor, selectable colour temperature so you can choose warm or cool light, dimming options, and lower running costs for years to come.
If you are planning lighting work in 2027 or beyond, it is worth choosing fittings that will still comply when the rules land. We design and install efficient, tidy lighting schemes across High Peak, Buxton, Glossop, New Mills, Macclesfield and Stockport.
