Boiler Prices
Before you buy a new boiler, it's important to get all the facts and understand what will meet your needs.New boilers often cost a lot and are a significant investment with the cost of a new boiler ranging from £500 - £2,500, with installation costs on top.

Even with the up front costs, there are some major benefits to upgrading and replacing an older, out dated boiler.

• New boilers are often more energy efficient, meaning that whilst boiler replacement can be costly, it can also result in savings on household energy bills, as modern boilers can result in savings of up to 50% on energy bills.

• If you have an older boiler that is non condensing it will probably be classed as a band G boiler, with an energy efficiency of less than 70%. If you replace your old boiler with a current ErP 'A rated' condensing Vaillant boiler it will have an energy efficiency of 90%. This could mean a saving of up to £300 a year on energy bills.
• Savings will depend on your house size and type, and the current levels of energy efficiency your house has. The more insulated your home, the less energy your boiler has to use to maintain the right temperature for you. Find out more about heating tips and how to reduce monthly bills.
