What is Boiler Plus?

Boiler Plus is legislation that sets minimum standards for new boiler installations in England. Here is what you need to know in plain English:

Minimum Efficiency

New combi boilers must have a minimum ErP efficiency of 92%. This means at least 92p of every GBP1 spent on gas goes directly to heating your home.

Most modern boilers we install achieve 93-94% efficiency.

Energy-Saving Measure

You must also have at least one of these energy-saving measures installed with your new combi boiler:

  • • Smart thermostat (most popular)
  • • Weather compensation
  • • Load compensation
  • • Flue gas heat recovery

Boiler Plus Energy-Saving Options

Choose one of these options to meet Boiler Plus requirements. Most customers choose a smart thermostat.

Most Popular

Smart Thermostat

Internet-connected thermostats like Nest, Hive, or Tado that allow remote control and learning features.

Weather Compensation

Outdoor sensors that automatically adjust boiler output based on external temperature for optimal efficiency.

Load Compensation

Built-in controls that modulate boiler output based on how far the room is from the set temperature.

Flue Gas Heat Recovery

Captures waste heat from the flue to preheat cold water, boosting efficiency by up to 4%.

Part L Building Regulations Explained

Part L covers the conservation of fuel and power. Here is what it means for your heating installation:

Boiler Efficiency

Minimum efficiency standards that new boilers must meet.

Controls Standards

Requirements for thermostats, timers, and zone controls.

System Design

Proper sizing and design of heating systems for the property.

Pipework Insulation

Hot water and heating pipes must be insulated to minimum standards.

Commissioning

New systems must be properly commissioned and tested.

Water Treatment

Systems must be flushed and treated to protect against corrosion and scale.

Our Level 3 qualification means we are trained to design and install heating systems that meet all of these requirements - so your new boiler runs efficiently from day one.
