Central heating installation: what price to expect

Installing a new central heating system is incredibly costly. Think about all the components needed and you can start to visualise the high total price of both supply and labour.

With everything involved, you need to have a general idea of the cost to avoid nasty surprises. If you know the average price of a central heating system, you will be better informed when determining whether a quote is reasonable or not.

That being said, the type of heating system and the specific details of the installation can vary greatly depending on multiple factors in your home. Because of this, it is difficult to calculate an exact price.
