How Much is a New Boiler in 2021 (Buying Guide)

How much is a new boiler

Our comprehensive guide on all the variables and associated costs will help you figure out the sort of price you will need to pay for your new boiler.

The question ‘how much is new boiler’ is one of life’s great imponderables. There are just so many variables that go into answering the question, it is simply impossible to give a definitive response. Equally, no two people will get the same answer to the question.

If you would like to get an exact price, HEATABLE can help you.

That doesn’t mean people don’t try though and a quick Google search will reveal hundreds of different articles on this very topic. Few of them are in any way comprehensive though.

Equally, you could ask a plumber or a heating engineer. But they will ask you dozens of different questions before giving you a quote. And if they don’t, they have just plucked a figure out of the air and you will probably end up paying too much.

Hopefully, this article is different. While there is no clear cut answer, in this guide we will seek to cover off all the variables and give you all the information you need to at least make an educated guess on what your new boiler will cost. We will also point you in the direction of some online resources that could help you save a bundle too.

What type of boiler do you need?

There are various different types of boiler you can buy and some will set you back more than others.

The two most common types of boilers are regular boilers (sometimes called system boilers) and combi boilers:

  • Regular/System Boiler – Regular boilers have a separate water cylinder, which is usually located somewhere in your house in an airing cupboard. They will also have a water tank which will most likely be located in your loft. Regular boilers do not produce instant hot water on demand but they are ideal for large homes with multiple bathrooms.
  • Combi Boiler – A Combination Boiler is a boiler that controls both heating and hot water. There is no water cylinder or water tank required and a combi boiler will deliver everything instantly and on-demand. They can work in most houses but are more common in smaller properties.

When buying a new boiler, most people will stick with the same system they already have. Switching from a regular boiler to a combi boiler (few people switch the other way) will cost you more. There are a lot of other variables that can affect the price of your boiler, which we will come to below. But in board terms, purchasing and installing a new regular and combi boiler will cost:

  • Regular Boiler – £1,500 – £3,000.
  • Combi Boiler – £1,500 – £3,500.

If you do want to switch from a regular boiler to a combi boiler, you will have additional costs such as upgrading pipework and removing your water tank and water cylinder. You can expect the whole job to cost:

  • Upgrading from a Regular Boiler to a Combi Boiler – £2,500 – £4,500

Installation Costs

New boiler installation costs

It is actually fairly easy to research the price of buying a new boiler. There are a number of variables to consider including the manufacturer and the length of the warranty but in general terms, the prices are fairly stable.

The great unknown in installing a new boiler is the installation cost. These can vary wildly depending on a whole host of factors. No-one should be impacted by the mall, but there are at least ten different variables that can affect the cost of installing a new boiler.

1. Location

Where you are located in the country is going to affect how much you have to pay for both the boiler itself and the labour costs.

If you live in a rural area, the chances are labour costs are going to be higher as your plumber or heating engineer is likely to have to travel further. Small cities and towns tend to have the most competitive installation costs, but this can depend on how much competition there is in the market.

The main exception to this is London. You may be used to reading about London premiums on things like house-prices and unfortunately, there is one for both boilers and installation costs too. Typically you can expect to pay around 25% more in the capital than elsewhere in the country.

If you are in London and want to save, our advice would be to shop around. There are good deals to be found for boilers out there. Another option is to seek a heating engineer based outside London who doesn’t mind travelling in. Alternatively, consider using an online service like HEATABLE.

2. Warranties

Your boiler will come with a standard warranty but a lot of manufacturers and their retail partners will offer extended warranties of up to ten years.

These will inevitably cost more money up-front but offer the prospect of saving money further down the line if your new boiler breaks down. It is like an insurance scheme and tempting for many users.

Be aware that as well as the cost of the extended warranty itself, which can be several hundred pounds, it may also require you to fit other approved equipment, such as magnetic boiler filters, which should lengthen your boilers service life. It is a sensible precaution to take but these all cost more money too.

3. Labour

Labour costs can vary for all sorts of different reasons. Different businesses and individual labourers will charge different rates. They may also charge different rates depending on location, how much work needs doing, the type of boiler being installed, and the number of labourers needed to complete the job.

The standard advice for this type of work is to get a minimum of three quotes. We would advise at least three and ideally up to five. We would also suggest you do some research into the business or individual you are considering hiring. You want someone who is reliable and does a good job.

The cheapest quote is not always going to tick these boxes and often you can save more in the long run by spending a little more up top.

4. Relocation

Simply switching out one boiler for another is not that complicated a job. But often, when people replace a boiler, they want to move it.

Boilers are not attractive things and if people have the chance to shift it from their kitchen or hall into the utility room or the downstairs loo, they usually want to.

But be aware, this can be a major job involving laying lots of new pipes and plenty of manual labour. It, therefore, can also add quite a lot to your labour costs.

5. Upgrading the mains gas pipe

Older heating systems are usually connected to the mains using a 15mm pipe. However, modern regulations require all new boilers to be connected to the mains with a 22mm pipe.

If you have the old sized pipes, these will need to be upgraded and that can sometimes be a labour-intensive and therefore costly job.

In particularly old systems, the pipes may even be made of toxic materials such as lead. In these cases, replacement is also essential, but sadly no less expensive.

6. Flue costs

Your boiler’s flue is the large pipe that leads from your boiler to outside your home. It is an essential feature which allows both condensation and flue gases to get out of your boiler safely. If your flue needs replacing this can affect the cost of your installation.

Most boilers just require a horizontal flue which goes out of the closest wall and just involves a little bit of drilling to install.

But some require a vertical flue and this has to leave through your roof. The work to install this is much greater and therefore, inevitably, so is the price. It is worth considering the type of flue you need while choosing your boiler.

7. Plume Kit

Under the UK’s Gas Safe regulations, you are required to fit a plume kit to your boiler’s flue if the gases it is releasing could have an adverse effect on yourself or others.

If your flue pipe is too close to a window, your neighbour’s house, or your child’s Wendy house, you may have to fit one of these kits. This is not a complicated job and the kits only cost around £120 or so, but it all adds up.

8. Modern controller

When you get a new boiler, you probably want to invest in a new controller as well. These days you can opt for the standard wall-mounted thermostat, but a lot of people prefer to invest in an internet-enabled controller that allows them to control their temperatures and hot water from their smartphones.

There are no shortage of these devices available, but the prices can vary significantly. Expect to pay anything from a few hundred to over a thousand pounds if you want the latest gadget.

9. Chemical Flush

A chemical flush is a method of cleaning out your existing heating system. It essentially pushes chemicals through all the pipes in your house which dislodge and flush out any dirt, grime, and sludge that might have built up over the years.

There are various different types of flushes available but prices can vary from around £100 up to several hundred.

You should also be wary of opting for a power flush. As the name suggests, this is the strongest type of flush available. But if you have an old heating system, this can actually cause more problems than it solves and lead to more costs on top of the average £500 initial outlay.

10. Magnetic boiler filter

A magnetic boiler filter is a filter installed in your pipework which attracts small particles of metallic dirt that can be in the system. By trapping these, it stops them from getting into your boiler where they can cause long-term damage.

Often, the cost of installing one of these will be included in any quote you get. But this is not always the case and if it isn’t, the price can be between £100 and £200.

Summary

It is impossible to put a precise figure on how much it will cost you to buy and install a new boiler. As we have explained in this article, there are so many variables involved that no two quotes will ever be exactly the same.

But, in this guide, we have tried to outline what all of these variables are and, where possible, we have provided some estimates of what costs might be. This information should put you in a great position to go out and find the most competitive quote you can.

We have also recommended the site that we believe will offer the most competitive prices both for a new boiler itself and the installation. HEATABLE is the site in question and we have outlined why it is rated so highly and what it can do for you.
