Baxi Boiler Installation Prices: How to Save Money in 2024

baxi boiler

In an era where energy efficiency and reliability are paramount for most home heating solutions, the name Baxi boiler stands as a beacon of excellence.

Manufacturing heating units since 1866, Baxi has an award-winning customer support unit and industry-leading products. Baxi boilers are produced in the United Kingdom, with a manufacturing facility located in Preston, near the company’s original establishment in 1866.

This article will shed some light on the best Baxi boiler options as well as Baxi boiler prices for combi, conventional, and system boilers in the UK and why they’re the best option if you need a cheap heating system.

Yet even the most thorough boiler guide can’t replace tips from a seasoned heating engineer who can determine the new boiler cost based on your housing situation and budget. 

However, searching for a trusted engineer on your own can stretch for days and easily become a stressful and daunting task you’d want to delegate.

Thankfully, Household Quotes can help you avoid the hassle. Filling out our form takes only 30 seconds and brings up to 3 free quotes from vetted heating experts near you. Compare the quotes without committing to any orders. Click the button below to get started.

Baxi boiler prices

How much is a Baxi boiler? Let’s clear up the Baxi boiler cost depending on the output and model type. 

Baxi boiler prices
Type of Baxi BoilerPower Supply (kW)Estimated Supply CostEstimated Labour CostTotal Estimated Cost
Baxi combi gas boiler21.2–34.4£610–£1,307£500–£1,500£1,110–£2,807
Baxi conventional boiler12–30£695–£944£500–£1,500£1,195–£2,444
Baxi system boiler15–32£711–£1,032£500–£1,500£1,211– £2,532

However, these figures in the table are just rough estimates. While combi boiler prices are usually lower, the cost of additional materials might push the total upwards. A heating professional could guide you through the installation process and calculate an individual price for your property.

Yet finding an engineer takes hours of browsing for local heating experts, going through reviews, and eventually calling them to jot down their prices. Sounds tiring, long, and stressful, doesn’t it?

Household Quotes has got you covered. With our network of trusted and vetted Gas Safe registered heating engineers, you can find the best deals for a new Baxi boiler. 

We can find you up to 3 boiler quotes from our installers to eliminate the risk of overpaying. Simply fill out our quick and easy form to get 3 quotes for free and at no obligation. Just fill out the form at the top of the page and you’ll be on your way!

What influences the Baxi boiler costs?

baxi boiler factors

Let’s take a look at the aspects that affect the price you’ll pay for your new Baxi boiler, considering size, output, type, location, and more.

Boiler situation

If you’re converting your boiler to another type then this will impact how much you pay for its installation. A like-for-like boiler replacement is typically more affordable as it requires less labour and wiring work. However, if you’re converting from one type of boiler to the next it is likely to take longer and therefore cost more, like replacing your conventional boiler with a combi.

It’s also important to keep in mind that conventional boilers are similar to system boilers in that they both require a hot water storage cylinder. So, a conventional boiler will also require a cold water cistern, usually placed in the attic. If you do not have the storage space for a cistern, a regular boiler may not be the best option for you.

The only like-for-like boiler swap that is not possible in the UK is during back boiler replacements. Replacement back boilers are no longer available to buy since they are very outdated and inefficient.

Boiler size

Before purchasing, it’s important to make sure that you know what the right size is for your needs, as you don’t want to spend money on a boiler that’s far too big for your house.

If you purchase a boiler that is too powerful, you will waste money on energy bills. On the other hand, if you install a boiler that does not produce a sufficient quantity of heat for your home, your central heating system cost will shade all possible financial benefits. For smaller homes with up to two bathrooms, a compact combi boiler may comfortably meet all your heating needs.

Learn about the best flow rate combi boilers.

Boiler type

As we can see from the comparison table above, there are a few different types of Baxi boiler options available, all carrying slightly different price points. This is because these boilers vary in terms of their capacity, features, and efficiency levels, which can impact both their upfront cost and long-term operating expenses. 

Additionally, factors such as installation complexity, warranty coverage, and regional market conditions also contribute to the price differences among Baxi boiler models.

Before we dive into the best Baxi boiler model range, it’s important to know the difference between combi boiler and system boiler types and what a conventional boiler is. Let’s decide which boiler you probably need and how complex the installation might turn out to be.

Best boilers for different households

Starting with the Baxi combi boiler range, the most commonly installed across the country. For a power supply of between 21.2 and 26.4kW, you can expect Baxi combi boiler prices of around £610 to £1,307. When labour fees are added on, your total estimated price will level out at £1,110 to £2,807.

Boiler relocation

It’s good to note that you’ll pay more for a new boiler if you choose to have it installed in a different location within your home. That’s because there’ll be additional piping required for the fit as well as additional labour costs so the installation will take longer to complete.

Replacing a like-for-like boiler in the same position will be more cost-effective than changing the location and the type of boiler, as the latter will require new pipework to be installed. The pipework and fittings can cost between £300 to £600.

Energy consumption

Homeowners need to take into account boiler efficiency and the most suitable fuel for their properties for the best results possible (reduced bills, of course). A more efficient boiler will use less energy to heat your home and this way lower your energy bills.

Energy costs, in their turn, may be affected by the energy price caps. As of October 2023, the general costs for electricity are around £0.27/kWh, 7 pence per kWh of gas, oil is 10.4 pence per kWh and LPG is 12.2 pence per kWh. However, the electric boiler vs gas boiler debate is more complicated because prices can fluctuate and many homes may not have a gas main connection.

Exact figures can change and fluctuate based on the fuel market, so it’s a good idea to get up-to-date information when you come to switch from the Energy Savings Trust. 

It’s also worth noting that gas boilers may become rarer in the future. The UK government is planning to phase them out by banning them from new properties as of 2025, followed by a blanket gas boiler ban 2035 onwards. To learn more about the benefits of switching to a renewable heating system, check out our dedicated gas boiler vs heat pump page.

Alternatively, you could reach out to a Gas Safe Engineer for more tailored information. Yet the cold hard fact is it takes days of difficult and stressful research to find an experienced professional on your own.
