Size

Put simply, the bigger the boiler, the more it will cost, but it is important that you get the right size for your home. Too small and it will be unable to keep up with the heating and hot water needs of your home, but too big and you’ll just be spending more on a boiler than you need to.

Changing boiler type or location

One big factor in the cost of your boiler installation is whether you want to change the type of boiler you have or its location in your home. This is due to the additional installation time and materials needed for the job. You may have added another bathroom to your home and need more hot water, so switching from a combi to a system boiler makes sense. Or maybe you’re carrying out renovations and need to free up space in your kitchen by moving your boiler to your utility room. As each situation is different, there is no set price for this additional work, but it will add to the costs.

Heating control upgrade

When upgrading your boiler you may also want to consider upgrading to a smart heating control, such as the Worcester Bosch EasyControl. The device lets you control your heating and hot water from anywhere with an app, as well as automatically turning the heat off when no one is home. An EasyControl costs £260 and they can help to reduce your heating bills and increase the ErP rating of your system by 5%. Not only that, most smart thermostats are compatible with all boiler types and manufacturers.

Guarantee

When purchasing a boiler, your installer will give you options around the guarantee length you want. The longer the guarantee you opt for, the higher the initial cost will be. However, the longer the guarantee, the longer you are covered if something goes wrong, which could save you a lot of money. It’s worth thinking about taking out a service plan when you buy a new boiler, which includes annual services to check your boiler’s efficiency and maintain the guarantee.

Finance

If you need to, you can spread the cost of a new boiler. Different companies offer different finance options. Some monthly finance prices might look cheap on the face of it, but not many installers offer interest-free credit, so you ultimately end up paying a lot more than you need to. If you are planning on using finance,  look for providers who offer interest free finance like us (we are a credit broker not a lender) - this means that you can buy a boiler, interest-free, with no additional charges – you’ll only pay for the boiler and its installation in your home.

Cost of combi boilers

Combi boilers are the most common type of boiler and work by heating up the water from the mains on demand, meaning they are more cost effective and energy efficient compared to other boilers. Additionally, as there is no need for a hot water cylinder, they also take up very little space in your home, making combi boilers ideal for small to medium size homes where you want to be saving space. Depending on the model or make you choose, combi boilers start from £1,995 if you buy from us online.

 

Cost of system boilers

System boilers are perfect for homes with two or more bathrooms and unlike regular boilers, there is no need for a cold water storage tank in the loft. Instead system boilers heat water and store it in a hot water cylinder (generally installed in your airing cupboard) allowing hot water to be delivered to multiple taps at the same time. The addition of the hot water tank means that system boilers are more expensive than combi boilers, with ours starting from £2,549.

Cost of regular boilers

Regular boilers are linked to a hot water cylinder making them a good option if you have several people living in your home and often need to use hot water at the same time. They’re also a great option if you live in an area with low water pressure. With regular boilers, our costs start at £2,375, depending on the complexity of the install as well as which model you choose.
