Fitting a new boiler is a significant decision for any homeowner, especially with the range of options and the costs involved. Unlike some home upgrades, it’s not something that can be tackled with a bit of DIY – it needs a qualified professional, ideally a Gas Safe registered engineer, to handle the process safely and efficiently.
This guide will cover what to expect and consider as you embark on the boiler installation journey, aiming to make the process smoother, safer, and ultimately more cost-effective.
Why You Need a Professional Boiler Installation
Let’s get this clear from the start: boiler fitting isn’t a DIY project. A boiler is central to your heating and hot water, and if installed incorrectly, it can cause dangerous situations and even void warranties. A Gas Safe registered engineer, such as the ones at Lazard, is essential not only for safety but also for legal compliance. This certification assures you that the person working on your boiler is qualified to handle gas appliances, keeping both you and your property safe.
Every year, there are still approximately 30 accidental deaths from acute CO poisoning in England and Wales and over 200 non-fatal poisonings requiring hospital admission. This can be due to a boiler being installed incorrectly.
The process may involve more than simply swapping out an old boiler. Engineers assess factors such as boiler size, hot water demand, and the existing central heating system before recommending the best boiler for your needs. This initial evaluation can be as crucial as the installation itself. After all, a boiler that’s too small will struggle to keep up, while an oversized boiler will waste energy and cost more in the long run.

Choosing the Right Boiler: Combi, System, or Conventional?
The next step is choosing a suitable boiler type. If you’re unfamiliar, boilers generally come in three main types: combi boilers, system boilers, and conventional boilers. Each has its pros and cons, and the right choice depends on your household size, heating and hot water needs, and even the layout of your home.
- Combi Boiler: A combi boiler, short for combination boiler, is a popular choice, especially in smaller homes or flats. This type heats water on demand, eliminating the need for a storage tank and saving space. Combi boilers tend to be more energy-efficient since they don’t need to maintain a hot water supply continuously. However, they may struggle in larger homes with high simultaneous hot water usage.
- System Boiler: A system boiler is a middle-ground option. It works with a hot water storage cylinder, making it suitable for households with higher hot water needs. Unlike conventional boilers, system boilers are closed systems, meaning fewer components are exposed to air, which reduces the risk of pressure loss and the need for frequent power flushing.
- Conventional Boiler: Also known as regular boilers, conventional boilers are typically best suited for larger homes where hot water demand is high. They require both a hot water cylinder and a cold water storage tank, which can take up a significant amount of space. Conventional boilers offer excellent heating capacity but are less energy-efficient due to the continuous heating cycle needed to maintain the hot water supply.
Each boiler type has specific benefits, but an experienced engineer will help you assess which type suits your home best based on boiler installation costs, space requirements, and your long-term needs.

The Boiler Installation Process: What to Expect
Boiler installation doesn’t just mean plugging in a new appliance. Here’s an overview of the installation process to give you an idea of what’s involved:
- Initial Assessment and Quotes: A reputable heating company will start with a thorough assessment of your home’s heating system. This includes inspecting the existing boiler, discussing your heating needs, and ensuring that your new boiler fits with your central heating layout.
- Choosing the Boiler and Setting the Installation Date: Based on the assessment, the engineer will recommend the best boiler model and provide a detailed quote covering installation costs, parts, and labour. It’s wise to get multiple quotes to compare boiler costs and avoid unexpected surprises. Once you decide, the installation date is set.
- Removing the Old Boiler: If you’re replacing an old boiler, the engineer will carefully disconnect and remove it. The process can get a bit messy, particularly if it involves a power flush of your system to clear out any accumulated sludge or debris that could impair your new boiler’s performance.
- Fitting the New Boiler: The new boiler is then carefully installed according to manufacturer specifications and regulatory standards. This step includes securing the boiler, connecting it to gas and water supplies, and integrating it with your home’s heating system and boiler controls. The engineer will check that everything is functioning correctly and conduct a series of safety tests.
- Testing and Handover: The final step is thorough testing to confirm that the boiler works properly. You’ll also receive guidance on operating the boiler controls, scheduling regular servicing, and troubleshooting. The engineer will document the installation and issue a Gas Safe certificate – make sure you keep this for future reference, as it’s vital for your records and any warranty claims.

How often should I get my boiler serviced?
Although your boiler may not be broken or experiencing issues, it’s best to service your boiler once a year.
An annual service on your boiler could help to highlight issues before they become urgent or overly expensive; it also helps to keep your boiler running more efficiently, prolonging the lifespan of your heating system and saving you money in the long run.
For any rental property boilers not working, you need to also talk to your landowner just in case they have a plan with a plumbing service provider.
Understanding Boiler Installation Costs
When budgeting for a boiler replacement, installation costs can vary significantly based on several factors. These may include:
- Type of Boiler: A combi boiler might cost less to install than a system or conventional boiler due to fewer components and quicker installation.
- Boiler Size: Larger boilers generally cost more. This decision should align with your home’s needs to avoid energy wastage.
- Additional Parts and Services: Sometimes additional components, like a new flue or thermostat, are necessary. Power flushing an old central heating system before installation might also be recommended for optimal performance, adding to the overall cost.
Each home has unique requirements, so there’s no universal boiler installation cost. An upfront investment in a modern boiler, installed by a qualified professional, will offer long-term savings in energy efficiency and reduced maintenance issues.
