Replacing an outdated boiler can save you up to 30% on energy usage. We install only premium, high-performance boilers from trusted manufacturers such as Worcester Bosch and Vaillant, offering superior reliability, long term efficiency, and smart compatibility.
Every new boiler installation in Roehampton is designed around your property’s specific needs, and includes:
Yes. Replacing an old G-rated boiler with a modern A-rated condensing boiler can reduce heating costs because modern boilers are over 90% efficient, compared with many older boilers, which waste much more heat.
Estimated annual savings when upgrading from an old G-rated boiler include:
• Detached house: up to £630 per year
• Semi-detached or terraced house: around £415 per year
Actual savings depend on the size of the property, the age of the existing boiler, and how efficiently the heating system is run. Click here to learn more about this.
Yes. When installing a new boiler near Roehampton, we can install Hive or Tado smart heating controls.
These allow remote heating control, scheduling, and improved energy efficiency.
Choosing the correct boiler size (measured in kilowatts – kW) is important when installing a new boiler. The required size depends on factors such as:
• Number of radiators
• Property size and insulation
• Number of bathrooms and hot water demand
• Heating system layout
A common misconception is that a more powerful boiler is always better, but this is not the case.
If a boiler is oversized, it can produce more heat than the heating system requires. This causes the boiler to switch on and off repeatedly, a process known as short cycling.
Short cycling can lead to:
• Reduced efficiency
• Increased gas consumption
• Greater wear on internal components
• Shorter boiler lifespan
A correctly sized boiler runs in longer, steady heating cycles, which improves efficiency and provides more consistent heating.
Whether you’re upgrading a combi, system, or regular boiler or System Conversion in Roehampton (converting from one type to another) our Gas Safe Registered engineers provide:
Ideal for customers wanting maximum performance or servicing older or high-demand boilers.
Typical boiler installation labour costs near Roehampton are:
• Replacing an existing combi boiler – £1,000 (inc VAT)
• System conversion from Regular to Combi boiler – £1,500 – £2000 (inc VAT)
• System conversion from Regular to System boiler – £1,300 (inc VAT)
These prices cover installation labour. The total cost depends on the boiler model, pipework adjustments, heating system layout, and any upgrades required during installation.
Most like-for-like boiler replacements take around one day to complete.
More complex installations may take longer, for example:
• Boiler system conversions
• Boiler relocation to another room
• Major pipework modifications
• Heating system flushing or power flushing
These installations may take two to three days, depending on the complexity of the heating system.
Many homeowners convert from regular or system boilers to combi boilers to remove loft tanks and hot water cylinders.
Combi boilers provide hot water on demand and free up storage space.
However, homes with multiple bathrooms may still benefit from a system boiler and hot water cylinder. Click here to see more information about system conversions.
Typical UK estimates for boiler conversions including boiler, parts and materials are:
• Conventional → Combi: £3500
• Conventional → System: £2,800 – £3250
Conversions cost more than like-for-like replacements because tanks, cylinders, and pipework often need to be removed or modified.
Relocating a boiler typically adds £1,000 or more to the installation cost because the work may involve:
• New gas pipework
• Heating pipe rerouting
• New flue position
• Condensate drainage adjustments
• Electrical alterations
The most suitable boiler depends on the size of the property and hot water demand.
The three main types of boilers installed in UK homes are:
Combi boilers
Provide hot water directly from the boiler without a cylinder and are ideal for smaller homes.
System boilers
Work with a hot water cylinder and are often better for homes with multiple bathrooms.
Conventional boilers
Used in older systems with tanks and cylinders.
During a boiler installation near Roehampton, the heating system is assessed to determine the most suitable boiler type.
Yes. All gas boiler installations must be notified to your local council Building Regulations through Gas Safe Register, confirming the installation complies with UK regulations.
After installation, you should receive on the same day:
• Gas Safe Building Regulations certificate
• Boiler commissioning paperwork
• Manufacturer warranty registration
These confirm the installation has been completed safely and correctly.
A professional boiler installation by a Gas Safe engineer includes:
• Removal and disposal of the existing boiler and all waste
• Installation of the new boiler
• Pipework adjustments where required
• Chemical flushing of the heating system
• Benchmark Commissioning and safety testing
• Gas Safe Building Regulations and council notification
• Warranty documents provided same day on commissioning
Commissioning ensures the boiler is operating safely by checking gas pressure, combustion readings, and correct system operation.

Yes. Boilers can be relocated to another area of the home such as:
• A kitchen cupboard
• The loft
• A utility room
• A garage
However relocating a boiler requires additional pipework, flue adjustments, and condensate drainage changes.
Sometimes. Older heating systems often use 15mm gas pipework, which may not provide enough gas for modern boilers.
If the gas pipe is undersized the boiler may experience:
• Ignition problems
• Poor combustion
• Reduced efficiency
• Boiler lockouts
During installation the gas supply is tested and upgraded from the gas meter to the boiler in 22mm or 28mm gas supply pipework if required.
During installation a Gas Safe engineer will check:
• Gas working pressure
• Gas pipe sizing
• Combustion readings using a flue gas analyser
• Appliance gas rate
These tests ensure the boiler operates safely and efficiently.
Yes. Hive and Tado systems can control individual radiators using smart radiator valves, allowing rooms to be heated independently.
Yes. Hive and Tado thermostats are compatible with:
• Combi boilers
• System boilers
• Conventional boilers
Yes. Smart heating systems can create multiple heating zones, allowing different parts of the home to be heated independently.
Yes. Hive and Tado smart heating systems can create separate heating zones within the property, allowing upstairs and downstairs areas to operate independently.
This means different temperatures and heating schedules can be used in different parts of the house, helping improve comfort and reduce unnecessary heating.
When installing a new boiler near Roehampton, smart heating controls can be configured so the boiler, thermostats, and motorised valves all work together correctly.
Both Hive and Tado can work well in larger homes, but the best setup depends on the property layout and number of heating zones.
Hive multizone systems commonly use separate receivers for each heating zone, while Tado systems typically use a central wireless receiver with smart thermostats and radiator valves communicating through the system network.
For larger homes with multiple heating zones, careful planning of thermostats, receivers, and heating controls is important to ensure reliable communication and stable heating control throughout the property.
