We're applying for a grant to help with energy-saving measures. Mostly this will be secondary glazing but we have to put in everything that we want to do out of the things the surveyors identified*, in one application.
Thus I'm on the hunt for the non-LED bulbs. Admittedly, changing CFL bulbs to LED isn't really energy-saving, but more a case of not having to wait two minutes after turning it on before being able to see anything.
* Including stuffing the chimneys with sheep. Actually they said balloons, but sheep are a bit more 'eco'.
