Making your cosy loft conversion in Essex both eco-friendly and economical goes hand-in-hand when using renewable sources of energy while constructing and furnishing it. Start by installing solar panels on the roof to use natural light more efficiently – this way you can reduce power costs substantially over time. Insulating walls is another great way to save money on bills; opt for thick padding that meets current building regulations for optimal results. Switching lights off when leaving the area is another essential tip; if you're not able to do so manually, then consider connecting them to timers instead. Ultimately by taking these simple steps into account you'll no longer have to worry about hefty bills nor environmentally irresponsible practices!
