New Boiler Installations by Lotus Energy

Lotus Energy supplies and installs gas boilers in and around Guildford, Surrey. We are Gas Safe registered and we fit Viessmann, Vaillant and Glow-worm. All three are reliable, have good parts availability, and we know them well enough to fault find without a phone call to the manufacturer.


If you are replacing a boiler anyway, ask us about a heat pump first. The Boiler Upgrade Scheme pays £7,500 towards one and the running cost can be lower than gas when the system is designed properly. We will tell you plainly if your house is not a good candidate. Either way, we remove the old boiler, fit the new one, flush the system, commission it, register the warranty and leave you with the paperwork.

What are the costs of buying a new boiler?

Vaillant new boiler by Lotus Energy Guildford Surrey

Before you buy a new boiler, it's important to have all relevant information and understand what model will meet your needs.


Upgrading your boiler can be a costly investment with the up front cost of the boiler and installation fees. However, there are multiple benefits of modernising and replacing your existing 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. Paired with a Vaillant heating and control or thermostat, you can potentially make even greater savings on your bills without being wasteful.
  • If you have an old 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 existing boiler with a current ErP 'A rated' condensing Vaillant boiler, it will have an energy efficiency of 90%.
  • 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 energy bills.
