While a more expensive boiler may have a higher upfront cost, it can lead to significant energy savings over its lifespan and provide additional comfort and convenience. Consulting with professionals like KoNi Gas Home Services can help homeowners make an informed decision based on their specific requirements and budget.
By understanding the factors that contribute to the cost of the boiler unit, homeowners can assess their options and choose a boiler that offers the best value for their investment. Remember, the cost of the boiler unit is just one component of the overall installation cost, and considering other factors like labor, additional materials, and the expertise of the installation company is equally important to ensure a successful and cost-effective installation.

2. Labour Cost:
The labor charges for installation depend on the complexity and duration of the installation process. Highly experienced and reputable companies like KoNi Gas Home Services might charge slightly more for their expertise, but it ensures a professional installation.

The cost of the flue can vary depending on its type and installation requirements. There are two main types of flues: horizontal and vertical. A horizontal flue is installed through an external wall, while a vertical flue is installed through the roof. If your property requires a vertical flue, the installation cost may be higher as it requires additional work and time to ensure proper sealing and weatherproofing. It is important to consult with professionals like KoNi Gas Home Services to determine the most suitable flue option for your property and understand the associated costs.
Including these additional materials in the cost breakdown provides a more comprehensive understanding of the expenses involved in gas combi boiler installation. It is advisable to discuss these materials with your chosen installation company and consider their benefits and costs before making a final decision.

Factors Influencing Installation Costs:
Several factors influence gas combi boiler installation costs. Let’s delve into each of these factors to gain a better understanding:
1. Boiler Type:
The type of boiler you choose significantly impacts the installation cost. Combi boilers tend to be more cost-effective compared to traditional boilers as they provide both heating and hot water without the need for a separate water tank. However, if you opt for a system or regular boiler, the installation cost may be higher due to the additional components involved. We discussed the types of boilers for installation in the previous article, which can be found here.
2. Location:
The location of your boiler installation plays a crucial role in determining the overall cost. If your boiler is easily accessible and there are no obstacles, the installation process is relatively straightforward, resulting in lower labor costs. However, if your boiler is located in a hard-to-reach area or requires extensive pipework, the installation cost may increase. Here are some factors that can affect the price of the installation cost:
- Accessibility: The accessibility of the boiler location can impact the ease and efficiency of the installation process. If the boiler is easily accessible and there are no obstacles in the way, such as furniture or other installations, it reduces the time and effort required for installation.
