How to Make Your Loft Conversion Energy Efficient

When you’re planning a loft conversion, ensuring it is energy efficient may not be your first priority. Instead, you’re likely to be thinking about the conversion itself, any relevant planning permissions and building regulations and, of course, what you’re going to do with all that extra space!

However, an energy efficient conversion is incredibly important. Your roof is a prime spot for heat loss within your home and, by making sure it is as efficient as possible, you can greatly reduce your energy bills. In addition, if you are planning to use your loft conversion as a bedroom or office space it is vital that it does not get too hot or too cold.

So whether you’re halfway through a conversion, or have got one in the pipeline, here are our top five tips for making sure it is as energy efficient as possible!


#1 Insulation

Insulation is key when creating an energy efficient loft conversion. It will help to regulate your home’s temperature, creating a thermal barrier to retain heat and eradicate drafts.

When you are creating a habitable area within your loft space it must conform to the Building Regulations Approved Document Part 1LB. This dictates that the u-value of the roof must be 0.18W/m2 or lower. Essentially, the lower the u-value, the higher the level of insulation and different materials will offer various levels of performance. Therefore, the regulations equate to a 270mm layer of fibre or wool insulation, a 175mm rigid board insulation or 125mm of spray foam.


#2 Double Glazing

Your windows are another significant source of heat loss so it is important that good quality, high performance options are installed. This means fitting double or even triple-glazed windows with a high energy efficiency rating.

Additionally, if you are able to choose the placement of a window within your loft conversion, it is often advised to opt for a south-facing one, as it can help add valuable heat and light to your loft space.


 #3 Heating

Whilst good quality insulation and double glazing will help to prevent your conversion from becoming too cold, it may still be necessary to invest in an adequate heating system. This can be achieved through extending your additional system (adding an extra radiator) or purchasing heaters. Whichever option you choose, try to make sure the system has a high energy efficiency rating and make sure its use is regulated – as with the rest of your home.


#4 Lighting

When choosing the lighting within your new loft space, you may want to consider using low-energy light bulbs. Not only will this enhance your conversion’s energy efficiency, but it can also save you money as they both last longer and use less electricity, reducing your bills as a result.


 #5 Renewable Energy

Undertaking a loft conversion can also provide a great opportunity to install solar panels on to your roof. This is particularly true if the project is a larger one and will already require the use of scaffolding.

There are two types of solar panels – solar photovoltaic (which generate electricity) and solar thermal (which heat water). Both are a fantastic way of maximising the environmental benefits of a loft conversion and will ensure your home is as energy efficient as possible.
