Getting a new boiler is an important upgrade for your home, but one of the biggest questions homeowners have is: How long will the installation take? The answer depends on several factors, including the type of boiler, the complexity of the job, and any additional work required.
If you're planning a boiler replacement, this guide will walk you through what to expect, typical installation times, and how to avoid unnecessary delays.
Factors That Affect Boiler Installation Time
Not all boiler installations are the same. Some can be completed within a few hours, while others may take a couple of days. Here are the key factors that can influence how long it takes:
Type of Boiler Being Installed – A like-for-like replacement (e.g., swapping an old combi boiler for a new one) is quicker than switching to a completely different system.
Upgrading vs. Replacing – If you're upgrading from a conventional boiler to a combi boiler, it will take longer as new pipework may be needed.
Condition of Existing Pipework – If your pipes are old or corroded, they might need replacing, adding to the installation time.
Location of the Boiler – Moving your boiler to a new location (e.g., from the kitchen to the loft) will require extra work and time.
Extra Work Required – Some installations involve additional tasks like installing new radiators, replacing flue pipes, or flushing the system to remove sludge buildup.
Understanding these factors can help you set realistic expectations before your boiler installation begins. You can also buy your materials in advance at Mr Central Heating to speed up the process.
Typical Installation Timelines
While the exact duration depends on your specific situation, here’s a general breakdown of how long different types of boiler installations take:
Straight Swap (Same Type, Same Location) – 4 to 6 hours
Boiler Upgrade (Different Type, Same Location) – 1 to 2 days
Full System Change (Different Type, New Location, Pipework Changes) – 2 to 3 days
Complex Installations (Including Extra Work & Smart Controls) – 3+ days
A simple replacement can often be completed in a day, but more complicated setups take longer due to additional work like rerouting pipes or installing modern heating controls.
What to Expect on Installation Day
Wondering what actually happens on the day your new boiler is fitted? Here’s a step-by-step breakdown of what you can expect:
Pre-Installation Checks – The engineer will assess the site, switch off the gas and water supply, and ensure everything is safe to proceed.
Removal of the Old Boiler – The existing boiler and any unnecessary components are disconnected and removed.
Fitting the New Boiler – Your new boiler is installed, along with any required pipework, wiring, or flue adjustments.
System Testing & Safety Checks – The engineer will test the system to ensure everything is working correctly, checking gas pressure, water flow, and thermostat settings.
Final Demonstration & Cleanup – Once the installation is complete, the engineer will show you how to use your new boiler and provide any necessary paperwork, including the warranty details.
How to Prepare for a Smooth Installation
A little preparation can make the installation process quicker and hassle-free. Here are a few things you can do:
Clear the Area – Ensure the space around your boiler is free from clutter so the engineer has easy access.
Plan for Water/Gas Shut-Off – Your gas and water supply will likely be turned off during installation, so plan accordingly.
Ensure Someone is Home – Be available to answer any questions the engineer may have during the installation.
Ask About Temporary Heating – If you’re replacing your boiler in winter, consider using electric heaters to stay warm while the installation is in progress.
How to Know You Have Found an Unreliable Supplier
When you need repair parts or a whole new system, you need to find a supplier you can trust. After all, you’ve got a time schedule and you might be without important elements in your home. Thankfully, the internet makes it easier to find suppliers and access the products you need at good prices.
However, the internet also means that rogue suppliers can appear. They might be inexperienced at what they do, which can impact you as a customer. Alternatively, they could be a scam. You need to know how to spot an unreliable supplier so you can stay away from them. Let’s take a look at how you can do this.
No Product Details
Most suppliers want to help their customers make good purchases. Indeed, they want to ensure that you’re buying parts that suit your needs and equipment that you understand. However, if you notice on the supplier’s website and they provide next to no product details, this could be a red flag. They’re only interested in getting your money.
No Good Reviews
Have you read the customer reviews yet? This is a good way to learn more about the supplier. If they don’t have any good reviews from customers, this can be a red flag. It shows that they aren’t providing the best products or services, which means that people don’t recommend them. It’s best to take this as a warning and avoid ordering and being disappointed.
No Customer Service
Most suppliers have systems in place where you can easily ask questions. After all, they need to be accommodating and informative so that you can make purchasing decisions. However, if you fail to see any way to get to know the team or speak to them directly, this might mean that they’re untrustworthy.
The time it takes to install a new boiler depends on factors like the type of system, the complexity of the job, and any additional work required. A straightforward replacement can be done in a few hours, while a full system change may take several days.
To ensure a smooth installation, plan ahead, work with a qualified engineer, and ask questions before the job begins. If you're considering upgrading your boiler, now is the perfect time to start the process!
