    Types of Boiler

    Let’s start with the type of gas boiler you want. There are three main types. A combi boiler, a system boiler and a conventional boiler. Most people in the UK have a combi boiler.

    Here are the differences.

    A combination boiler, or ‘combi’ boiler is the most popular kind in the UK. It provides heat and hot water without a water tank or cylinder.

    Hence it can suit almost any home and fits into almost any space. Furthermore, you get unlimited heat and hot water exactly when you need it.

    The main drawback to a combi boiler is that the water pressure is reduced if you need hot water from more than one tap at a time.

    So it’s not ideal for large households where people take showers at the same time.

    A system boiler is also known as a sealed system. It comes with a water cylinder which usually sits in an airing cupboard, so you’ll need room for the cylinder.

    It means that the water needs to heat up so you can’t get hot water instantly.

    However, system boilers are good for larger households because you can get hot water from multiple taps at the same time.

    Meanwhile, a conventional boiler is the largest type. It’s also known as open vent or a regular boiler and comes with both a cylinder and a tank, so it needs the most space.

    Once again, you will need to wait for the water to heat up, but it can heat water for multiple taps at the same time.

    How Much Is a Boiler on Its Own?

    Before you start looking at the cost of installation, it’s a good idea to understand the costs of a boiler by itself.

    Eventually, the costs of labour plus any warranties or extras will be added onto this, so start with a standalone boiler.

    You’ll discover that the price range varies considerably.

    For example, a new boiler costs anything between £600-£2,500 depending on the model you choose.

    For combi boilers, a budget model can cost from £500, but this rises to £900 for a mid range model. Whereas a premium model combi boiler is between £1,000 – £2,000.

    A new system boiler includes a water cylinder as well, so can cost from £600 for a budget model to £2,000 or a premium model.

    Then a conventional boiler requires a water cylinder and a tank so can be the more expensive option, up to £2,500.

    What Does Installation Cost?

    From this starting point, you can then add on the installation cost of the new gas boiler. This will depend on what company or engineer you use and where you want the boiler to be.

    Here are a few cost scenarios to help.

    1. Replacing a Combi Boiler for a New Combi Boiler in the Same Place

    This is a straightforward installation, replacing like for like. An estimate cost is around £1,600.

    2. Replacing a System Boiler With a Combi Boiler

    Here you are updating your boiler with a different type. This requires more labour to remove the infrastructure in place with the system boiler. Hence an estimate cost is around £2,500.

    3. New Boiler Installed in the House

    To install a completely new boiler where there hasn’t been one before. This includes labour to fit the boiler and connect it to the mains supply. Therefore a new gas boiler can cost around £2,800.

    Basically, the average cost of a new gas boiler is around £1,500-£1,800 including installation.

    But as above, this depends on the type of boiler you buy and the scenario you have at home. If the boiler needs moving, it will cost more.

    If there is a complex old boiler to remove and upgrade with a new one, it will also cost more in labour.

    The engineer may need to move pipes or carry out a chemical flush on the system so that a new boiler functions efficiently.

    What Is a Boiler Warranty or Guarantee?

    Before you choose the cheapest quote, consider any other costs involved and you may get a better deal elsewhere. Remember, the cheapest option is not always the best one.

    For example, a boiler warranty can potentially save you thousands of pounds in repair costs.

    The lifespan of a boiler is approximately 12-15 years, so if you buy a boiler with a 10 year warranty, then this will give you peace of mind for a long while.

    However, a warranty is not the same as a guarantee.

    A warranty is a contract to investigate the problem, but it may still cost to fix it. Whereas a guarantee is an arrangement to fix the problem unconditionally if it’s due to a manufacturing fault.

    Some manufacturers offer a free warranty of between 2-10 years. Whereas brands like Worcester Bosch offer a guarantee.

    Keep in mind that there are conditions of cover for your warranty or guarantee.

    It must be installed by a registered gas safety engineer, you must register the installation within 30 days and you must book an annual service.

    Otherwise the warranty or guarantee you have paid for is void.

    Smart Controls

    On top of this, you may be thinking about smart controls for your boiler to make it more efficient in your home. A smart thermostat can make a difference to the amount of heating you use.

    Smart heating from brands such as Hive, Nest and Tado allow homeowners more control over their heating.

    The average Hive installation is around £225 for materials and labour which can go up to £300.

    However, you could save yourself the cost of the smart controls within a year with the savings you make on your heating bills.

    Be aware that if you choose smart controls this will bump up the overall price for your boiler installation.
