New Boiler Installation Cost Guide

Your boiler is an important item in your home particularly when it gets close to winter. It’s essential that it’s working to its full potential to ensure that your home stays warm throughout. There’s nothing worse as the cold weather arrives then turning your boiler on for the first time in several months to find it isn’t working.

So what do you do when faced with this situation? Do you replace the boiler, or do you get it repaired? We’ve put together a guide to the cost of a new boiler installation talking you through the process to help make the transition to a warm home as easy as possible.

Do I need a new boiler installation?

There are a few ways of assessing whether your boiler is on the way out. Usually displays some of these typical signs (although this is not a substitute for professional opinion):

It always needs repairing: Just like a car, once something goes wrong it can start a bit of a domino effect.

There’s some strange noises: odd noises could be the sound of the parts wearing out as the boiler ages. Hearing this may signal you need a repair or replacement.

The boilers dripping: If your boiler has a leak then it needs to be looked at immediately. As well as being a major sign for boiler damage, it can also develop into a carbon monoxide leak which has the potential to be deadly. If you smell carbon monoxide call 0800 111 999 the National Gas Emergency Service.

The temperature fluctuates: Having a boiler that fluctuates in temperature or takes a while for the hot water to heat up is a sign that you may need to repair it. If repairing it doesn’t fix the problem, or it continues to break, you may need to look for a replacement.

Do you actually need a new boiler? Or should you look at getting your old one repaired? That depends on how often you're having to pay out to have it fixed. As previously mentioned if it’s constantly needing repairs then it may be worth replacing it as this may be less hassle and could avoids unexpected expenses.

Whether you need a replacement or repair should also be assessed by the amount a new boiler could potentially save you. If your boiler is old, then the likelihood is that it’s a lot less efficient than a new boiler model so it could be costing you more on your annual energy bill. If you’re old boiler is running at a 60% efficiency, then switching to a boiler that’s over 90% efficiency could save you roughly 30% on your yearly gas bill.

What to look for in a new boiler

There are quite a few things that you need to look at when purchasing a new boiler. It’s no small purchase so you need to ensure you take a lot of different factors into consideration, here is a list of what to look out for when purchasing a new boiler installation:

Reliability: This is a big one. Look at the reliability and reputation of the brand, and doing some online research is a great way to find out which brands are considered the best. There are some great reputable brands out there like Worcester Bosch, Vaillant, Vokera, Ideal, Baxi, Glow Worm & more, all with their various positive and negative points. Which? offer some great guides, but most of it is member only content, so forums like MoneySavingExpert or DIY forums are a good place to start.

Professional opinion: It’s worth getting a surveyor into your property to have a conversation on what boiler they think is best for your home. After all they are the experts. This is something we can arrange for you.

The type of boiler: There are three main types of boiler to choose from, combi, heat-only (regular) or system. They all have their pros & cons, but majority of UK homes have a combination boiler which is suitable for majority of homes, as long as they don’t have a very high demand for hot water. Having a like for like swap on boiler type could keep costs down.

kW output: The kW output determines the boilers ability to deal with the demand for hot water. The higher the kW output, the more bathrooms & radiators it can deal with. As a rough guide, 24-27kW may be okay for a two-bedroom, one-bathroom small house, but a large 4+ bedroom house with over 2 bathrooms will need a boiler with over 35kW output.

Efficiency matters: Going for a boiler with a high energy efficiency can save you loads of money in the long run on your energy bills. A boiler could even pay for itself over the duration of its lifetime, as according to the Energy Saving Trust you could save up to £320 a year from replacing your old boiler with a new A-rated condensing boiler. If the average boiler lasts for between 10-15 years, that’s a potential saving of between £3200 - £4800.

Getting the right size: This should be a given, but it depends on your home and it’s not always something that people consider. The boiler you purchase needs to be able to fit in the area where your pre-existing boiler is, unless you are planning on moving it which could be an expensive thing to do.

Boiler installation costs

The cost of getting a boiler installation varies massively, and without asking a series of questions, it’s hard to determine how much exactly you might pay for the installation. A boiler installation has different determining factors, here are a few:

Is it a like for like swap

Where you live and the availability of installers in your area

Moving the boilers location

Additional parts may be required such as new gas pipes, condensate pipes, any extra tanks or any other building work

Some boiler brands are easier to install than others

Keeping your new boiler in good shape

Finally, a few words of advice, keep your boiler in tip top condition. Boilers can last for years and years if you take care of them well with an annual service. Much like a car, boilers need that yearly attention to ensure that everything is working as it should be, and it helps to avoid any unexpected boiler breakdowns.

There are several things you can do every year to help ensure that your boiler is kept in good shape to name a few:

• Bleed your radiators to ensure they are working to their full potential. You could be leaving your boiler on for a longer time then needed because your radiators aren’t working properly. Often if a radiator has cold patches, it simply needs bleeding which is a quick task.

• Turning the boiler on periodically through the summer to wash away any potential dust & grit that may be starting to build up.

• Keeping the heat in your home is also an important one. By improving your windows, getting cavity wall insulation and insulating the loft may mean the energy efficiency of your home is improved. This in turn should mean you need to use your boilers less, reducing wear and tear.
