Having a new boiler installed is a big step – not just choosing the installer, but in the overall cost as well. A new boiler with the best features should be installed by a reliable company, with excellent customer service and aftercare. You can expect to pay anywhere between £1740 to £2400 for a boiler replacement, depending on the replacement type.
So how do you go about making the right choice?
This isn’t something to be taken lightly. However, it still needs to be a seamless process to give you the information you need without any additional stress.
Because of this, we’ve saved you from finding out everything yourself and covered what you need to consider when having your new boiler installed.
So relax! Everything’s broken down so that you know what to ask about when you make your decisions with your installer.
1. Choose a reliable boiler brand
This may seem like obvious advice, but all too often we make a choice on a new product based on popularity, or what our neighbours say, friends or family recommend. Support can certainly help, but so does doing your own research.
Doing your own research will save you many headaches in the long run, it will give you peace of mind knowing that you have picked the right boiler and system for your home.
But how is this done? One of the best methods is to look at feedback on review sites such as Trustpilot or Which?, because many installers include honest coverage of the boiler brands they help install.
Whatever the weather or time of year, a broken boiler is the last thing most homeowners want to deal with. A freezing shower might help you wake up in the morning, but you’ll quickly get sick of it! You can stop this from happening by going with a boiler brand that provides high-quality products, warranties, and excellent aftercare/servicing.
Whilst there are many boiler brands out there, here at B T Morgan we recommend Viessmann and Ariston. These boilers both come with exceptional warranties and the manufacturers have a range of boilers to suit every budget. They can meet your hot water and heating requirements for any property type and their customer service is exceptional.

2. Get advice from the best source available – your installer
As we mentioned in the introduction, advice from anywhere can be useful. You just need to be wary of anything biased for/against a particular brand. Even if you haven’t chosen one yet, you need to be able to choose a boiler that’s right for your property.
How’s this done? By speaking to the people who are installing it themselves.
Any reliable installer will agree they’ll need a profile of your property including your current system, what system you are looking to change to, and what your demand is for heating and DHW (Domestic Hot Water).
Take a 1-2 bedroom flat for instance, an open vent boiler is the least efficient boiler. A combination boiler is a better option for a 1-2 bedroom flat as it is compact, you get heating and hot water on demand with no need to replenish a large cylinder with hot water on a daily basis. This not only saves you money but because they are compact you can fit combi boilers almost anywhere in the home.
Discuss with your installer any preferences you may already have, but listen to their advice carefully. They’ll want what’s best for you and your property every time.
Have a look at some of our blogs below, they will help you to decide which boiler is best for you and your property:
3. Consider warranty and aftercare service
Why is aftercare for your boiler so important?
They’re just like any other piece of technology – on rare occasions they might suffer a fault that stops it performing as you’d expect. This is why you’ll need a warranty – the manufacturers will give you a parts and labour warranty with your new boiler and a contact number to call should this happen. In line with this, the terms of the warranty will be that the boiler is serviced annually, if you do not do this you run the risk of invalidating the warranty.
Keep in mind when replacing your old boiler a premium installer who knows the product well is always the better option. If they have a strong relationship with your chosen brand, they can typically offer you longer warranties. This will prevent unnecessary issues coming up during the installation process, and you’ll become a valued customer who’s well looked after, for a lot longer.
In most cases, if you have a fault on your boiler your first point of contact is the installer. They will have the knowledge to go through some checks with you to ensure that the fault is not user error and is a genuine fault with the boiler. They will contact the manufacturer on your behalf and arrange for them to contact you to arrange a call-out at your convenience.
If you pick the right manufacturer, call-outs can be within 24/48 hours and with a good fist fix rate should the boiler need to be repaired. Viessmann is one of these manufactures, they guarantee to be with you within these time frames and have a 95% first fix rate which they are very proud of.

4. Choose the right type of boiler
Ask yourself ‘What type of boiler do I need’ – it’ll save you a lot of hassle and aggressive sales tactics from people who just want to make a quick buck.
Depending on your property, you have several different boiler options available to you:
Combi boilers are the most popular type of boiler that people are upgrading their system from/to. They provide you with the hot water you need on an ‘as-and-when’ basis. This means you save a lot more money because the boiler’s heat exchanger transfers energy to directly heat the water only when it’s needed, drastically reducing wasted energy.
Another bonus with combi boilers is that you won’t need a storage tank or a hot water cylinder – these boilers are very compact and can fit easily into a standard kitchen cupboard, when space is limited.
High-efficiency combi boilers are suitable for most property types, smaller properties with a lower demand for hot water, to larger properties, say 2 bathrooms.
Storage Combi Boilers
Storage combis, can accommodate 3 bathrooms at a high flow rate, choosing the correct size combi can help keep running costs down.
Storage combis can provide up to 20 litres a minute, with an equivalent of 160 litres for the first 10 minutes, after that it reverts back to 14 litres a minute indefinitely.
As an example, the Viessmann V111-w 35kw can produce a high flow rate between 18-20 litres per minute for a period of 10 minutes. Then the 35kw boiler will deliver 14 litres per minute indefinitely. With the V111-W 35kw, to fill a bath will take approximately 8 minutes.
Also known as ‘Open Vent’, ‘Conventional’, or ‘Heat only’ boilers. They typically feature a cold water storage tank often placed in the attic, along with a hot water cylinder in an airing cupboard.
The hot water cylinder leaves little for the imagination – it’s where the heated water is readily stored to be used as soon as it’s needed. This is the least efficient system type however, if you are replacing an open vent to an open vent boiler this can be carried out with the least amount of disruption and save on installation costs.
An Open Vent boiler is usually the best option for properties with low incoming water pressure, that feature multiple bathrooms with a high demand for hot water out the taps and showers.
Out of the different types available, system boilers are often thought of as the middle-ground option. This is because like Combi Boilers, they take their supply directly from the mains, but also feature a hot water cylinder just like Regular/Open Vent boilers. Sealed system boilers are more efficient than open vent boilers, however the most efficient boiler type is a combination boiler.
This can often help with installation costs due to being a quicker process – you won’t need a storage tank in your attic for this one. A system boiler is usually the right choice when there’s limited space for a high demand for water without suffering any drops in pressure.

5. Make sure you understand boiler efficiency
Brand power is all well and good for making a good first impression, but one of the best rewards you can get from your boiler long term is how efficiently it provides you with heating and hot water.
View it in percentages; new condensing boilers typically start somewhere in the early 90 percentile, but obviously the higher, the better. With additional features like weather compensation and smart thermostat controls (more on that further down), efficiency can be boosted to around 92-94%. In financial terms, you’d gain £6-£8 per £100 a year, on your annual fuel spend.
Once again, this is something you’ll learn more about during the initial discussions with your installer. Be honest with what your requirements are, and you may be surprised by how much you can save in the long run.
For more information have a look at our post that asks ‘What’s the most energy efficient boiler?’
6. Make sure you choose the correct boiler size
No, we’re not talking about how physically big your boiler is – even if it’s still something to think about. What we mean by ‘boiler size’, is the power output measured in KW (Kilowatts) that’s been recommended for your property type.
Go with a boiler that’s too small, and you won’t be able to get enough hot water for your radiators, taps, baths and showers. Choose something that’s too big, and you’ll start having issues with overusing fuel, causing your bills to rise unnecessarily.
7. Be wary of initial costs – cheaper isn’t necessarily better
It’s always very tempting to save as much money as possible on the initial spending for a new boiler. After all, a modern condensing boiler can last upwards of 15 years, so it’s extremely important to choose one that can last that long without excessive and unnecessary repairs.
This is where you can decide how your money is spent on your heating. You can either:
- Make a larger initial payment for a top quality product with excellent warranty packages
- Get a cheap, unreliable boiler that incurs frequent repairs costs along with further stress
That’s why it’s vital you choose an installer with a strong relationship with the boiler manufacturer as we mentioned earlier; it usually means they’re able to install at a lower cost, while retaining that reliance and efficiency you’ll need to last you up to 15 years.
Replacing an old efficient boiler with a new efficient boiler can be a substantial cost for some and they may need help raising/finding the funds to pay for it. There are finance options available from reputable installers with various APR rates, subject to your financial circumstances and credit score. This finance can spread over 1-10 years depending on the amount you are looking to finance.

8. Consider additional features like weather compensation and smart thermostats to improve efficiency
Many homeowners prefer to be in control – including how their homes are heated.
This comes in many forms when deciding on your new boiler, but it’s also a great opportunity to include features like weather compensation technology and smart thermostats to make sure you save as much money as possible.
Weather compensation is what’s used to communicate between the outdoor sensor you’ll have installed on your property’s north facing wall. It works by detecting any changes in the temperature outside that can affect how much heat gets lost through the fabric of the building. So, when your boiler is informed of these changes, it knows to alter the temperature of the radiators to make sure there’s no unnecessary heat loss.
For thermostats, it’s good to make a choice at the same time as the boiler itself. Smart thermostats from brands like Nest, Tado and Hive can offer you some amazing ways to save money, such as knowing when you leave your property via a connected app on your smartphone, so that it knows when to switch the boiler off.
Smart thermostats such as Nest Generation 3 have key features like:
- You can control it from your phone or tablet
- It recognises when someone is at home
- It produces monthly efficiency reports
- Can invite multiple users
- They are fully compatible with Nest smoke alarms
- With remote access a responsible person can check, alter and adjust the heating temperatures from anywhere in the world, (Ideal for a carer or sibling to monitor a vulnerable or infirm person to ensure warmth in the home)
We all like to enjoy peace of mind. With an easy set-up process and learning algorithm that helps the thermostat understand your requirements and living habits, you no longer have the stress and responsibility of when to switch your boiler off. Much less to think about, with far more to save!
