Space is important to homeowners in the UK. As a result, many people are looking at different ways in which they can create more space around their home. One such way is by getting your boiler installation in the loft. Alternatively, you could have a brand new one installed up in the loft space from the outset.

The most commonplace in the home for a boiler is in the kitchen or hidden away in an airing cupboard. However, many homeowners prefer to hide them away entirely. What better place to hide it than an empty loft space?

This has subsequently allowed us to remove one of our wardrobes (creating extra floor space) as we can now store our towels, bedsheets and clothing in the space left by the old boiler. It has been handy!

If your boiler is up in the loft, it makes it a little bit more inconvenient if you need to check your boiler’s pressure.
