Boiler Installation Birmingham

If you have tried to search for advice and guides about boilers online before, you may know that there are lots of general guides, often with contradictory advice, and unfocused suggestions.

This guide is the opposite of that. It has been written exclusively for people who live in Birmingham and the surrounding area and contains focused, relevant, and up-to-date information.

So, if you live in Birmingham or the West Midlands and need to buy a replacement boiler, you will find all the information you need right here.

Buying a Boiler in Birmingham

Birmingham is traditionally England’s second city and is home to more than 1 million people. It sits at the centre of the West Midlands conurbation which has a population of just under 6 million people.

For people who call Birmingham and the surrounding area home, this is both a positive and a negative when it comes to buying a replacement boiler.

Being in such a densely populated area means that are lots of choices out there in terms of both places to buy your boiler and tradespeople to do work for you.

But the downside is that so many people means high demand and when it comes to heating engineers this can be a problem. The whole of the UK has a shortage of plumbers and heating engineers and Birmingham is no different. With high demand comes a shortage of availability tradesmen and this means higher prices and longer waits to get the job done.

If you want to avoid these issues and get your new boiler installed quickly and affordably, this guide has all the information you will need.

Who should you use to install a new boiler in Birmingham?

The question we asked most often about replacement boilers is who should be used to install a replacement. In Birmingham, with the pressures on local traders that we have already discussed, this is a particular issue.

The key here is quotes. The best way to ensure you are not overpaying is to get as many quotes as you can. We will generally recommend three quotes but this is a minimum and, to be honest, you can’t get too many.

Quotes give you information about the market and where prices are at in Birmingham and the West Midlands. They also give you the best chance of getting a good deal too.

When it comes to which companies to get quotes from, there are three main types you should be considering. We would advise you to seek at least one quote from each, but broadly speaking, we can tell you what to expect from each:

National Installation Companies

These are nationwide plumbing and heating installation companies. You probably know some of them as they frequently advertise on TV and in the papers. British Gas is the highest-profile one but there are others.

The key thing to remember about this type of company is that they have big overheads. National advertising campaigns are not cheap and these costs are ultimately paid for by their customers. They do have offers and deals from time to time, but usually, we would expect a quote from a national installation company to be the highest.

Local Heating and Gas Installers

Local companies and independent engineers will usually undercut national installation companies and often by as much as several hundred pounds.

There is no shortage of local tradespeople around Birmingham and the West Midlands but as we have already explained, demand in this region often outstrips the plentiful supply. Quality can be mixed too and it is important to choose a good engineer as well as a cost-effective one.

Word of mouth is often the best way to do this but make sure you get three or four people speaking highly about them before you choose an independent trader. Prices can still be higher than you need to pay too, so make sure you get enough quotes to ensure you are not overpaying.

Online Installation Companies

In recent years, the boiler installation market has been rather shaken up by the emergence of online installation companies. These new businesses operate entirely online and with low overheads. But they are still nationwide which means that they can deliver the best of both worlds.

It is amazing how many people who are looking to replace their boiler don’t think about an online installation company. But they can often undercut national and local installers for price and still deliver guaranteed high-quality service.

HEATABLE – Best Online Installer

There are a few online installers out there but the best on the market for us is HEATABLE.

HEATABLE has been around for a few years now and built up a deserved reputation for low prices and high-quality service. It offers a wide range of boilers from all the top manufacturers and its prices are hugely competitive.

There are always plenty of special offers available too which generally includes things like extended warranties. HEATABLE offers a range of flexible financing options too including 0% APR on some models.

It has a network of installers based nationwide, with plenty across Birmingham and the West Midlands. This means you can often get your new boiler purchased and installed as quickly as the next day.

If you are looking for quotes, you won’t go far wrong from trying HEATABLE. Just visit their website and fill in the online form there. It only takes 2 minutes and you won’t have to share any personal information.

What kind of fuel does your boiler use?

HEATABLE will then generate a fixed-price quote for a range of boilers ideally suited to your home. If you are happy with their offer, the price they generate is fixed and guaranteed.

You should get quotes from all sorts of different companies but we highly advise you to make sure one of them is from HEATABLE.

What type of boiler do you need?

As well as deciding who to use to install your new boiler, the other big decision you need to make is which type of boiler to choose. This is a big decision and there are a number of different variables you need to weigh up.

A lot of people will let their installer recommend a boiler. This can be fine but is a risk. National and local traders will have preferred manufacturers and models that they use. Some local traders may even have arrangements with wholesalers and manufacturers to push particular models.

This can mean that you are not always getting the best boiler to suit your property and your needs. It might also mean that you are spending more money than you need to as well.

It is therefore worth having a good idea about what make and model of boiler you want before speaking to installers and getting quotes. But how do you decide this? There are lots of things that will influence your decision.

Firstly, there is the type of fuel your boiler uses. There are various different options available:

  • Gas
  • LPG
  • Oil
  • Electricity
  • Renewable energy sources

In Birmingham and the West Midlands, most homes will be connected to mains gas fuel. Gas is the cheapest fuel to use and also has the widest variety of cost-effective boilers to choose from, so most people will opt for this.

The next question is what type of gas boiler you want to choose. There are various different types available including:

  • Combi Boiler
  • Regular Boiler
  • System Boiler
  • Compact Boiler

In Birmingham and the West Midlands, most people live in flats, apartments, or regular-sized homes. A combi boiler is usually the best choice for this type of property since it can generate heat and hot water without the need for a water tank.

If you already have a hot water tank and want to keep it and your airing cupboard, you will need a regular boiler. System boilers are mostly for commercial properties these days while a compact boiler is a type of combi boiler for small homes where space is at a premium.

What size boiler do you need?

When we talk about the size of a boiler we are referred to its power capacity rather than the physical size of the unit.

It is important to get this right because if your boiler is too small, it won’t be able to get all your radiators and hot water up to temperature and if it is too big you will find your gas bills are getting bigger unnecessarily.

Getting the right sized boiler is tricky and it is often best to get a qualified engineer to visit your property and advise you on the size you need. But to help you get a rough idea of what size boiler you will need, we have compiled a table averaging out the size of combi boiler needed for different sized properties.

Combi boilers come in three main size ranges:

  1. 24kW – 27kW
  2. 28kW – 34kW
  3. 35kW – 42kW

Based on these, you can estimate the size of the boiler you will need for your property. These sizes are assuming that your hot water usage is around average for the size of property you own:

Property TypeRadiatorsBathroomsBoiler Size
Apartments, 1 & 2 bed houses10 or fewer124kW-27kW
Medium size 2-4 bed homes10-15228kW-34kW
Larger Properties15-202+35kW-42kW

As well as calling out an engineer, another way to find out what sized boiler you need is to use an online boiler size calculator. There are several around but HEATABLE actually offers one of the best.

When you fill in the form on their website, they will ask you a lot of pertinent questions about your property, such as how many radiators and bathrooms you have. The site will then work out the best-sized boiler for your property and make some recommendations based on that.

Their selection includes a wide range of makes and models and this means that not only do you know what sized boiler you need, but also have an immediate idea about which boilers are best.

Birmingham boiler replacement: How much does it cost?

Like size, estimating the cost of a replacement boiler is not simple because there are so many variables involved in both the boiler itself and the installation.

In the following two sections, we will discuss the two main factors that can affect the price of your installation, but first, we will try to give you an outline of the price you can expect to pay for your new boiler.

To do this, we have to make a few assumptions and this will start with assuming that you live in an average-sized Birmingham property with average water usage and that you have been advised to choose a 24kW combi boiler.

If that is the situation you are in, you can expect your total bill for a new boiler and installation to be around £2,000.

It could be less than this. If you decide to get your new boiler through HEATABLE, there is currently a high-spec boiler that fits these requirements and is made by Worcester Bosch, one of the best-regarded UK manufacturers, available for just £1,700.

If this is a lot for you to find upfront, take a look at their finance deals. You might be able to spread the payments without incurring too much interest.

Cheaper boilers are available too but this will inevitably mean you have to compromise on quality. This might not bother you now, but it means your boiler is likely to start going wrong sooner and your repair bills will mount up.

In the long-run, you could end up spending more than you would have by getting a high-quality boiler upfront.

Moving Your Boiler

One of the things that can drive up the cost of installing a new boiler is if you need to move it to a different location in your home. Depending on where you are moving it to and how much work is involved, this can drive the price of a boiler installation up quite a lot.

The various quotes we have given in this guide are all based on a regular boiler replacement and assume that it will remain in the same location.

The quotes we have estimated so far in this guide assume that you will be keeping your boiler in the same location. But if you are moving your boiler that will mean new pipework, a new flue, more work and therefore more cost.

The main cause of this increased cost will be material and labour costs and these can quickly mount up. Another consideration that will also influence the cost will be the size of the boiler unit. If it is very large and too big for one installer to move on their own, you will need two people on-site and that will cost more too.

On average, you can expect a boiler relocation in Birmingham and the West Midlands to add something in the region of £350 – £750 to your total bill. A local engineer or an online installation firm like HEATABLE might be able to do it for less, but a big job could even wind up costing more.

What Extras Do You Need?

Whether you are moving your boiler to a new location or not, it is likely that your installer will recommend a number of extras in addition to the standard boiler installation.

You might instinctively dismiss all of these but don’t be quite so quick to do so. Some are really useful and can extend the life of your boiler and extend its service life quite considerably.

Three extras that are well worth considering include

  • Magnetic filter – A Magnetic Filter is a component that collects up metallic debris that might be floating around in your heating system. This debris can become sludge that can clog up your boiler and affect performance or even damage components.
  • Scale filter – Scale filters are important in hard water areas like Birmingham. Limescale build-ups are another thing that can damage components. But a scale filter helps to prevent this from happening and so reduces repair bills and extends the life of your boiler.
  • Hot / Power Flush – It is likely that before your new boiler is installed, your engineer will advise you to have a hot flush or a power flush to clean out any debris or sludge that has built up in the system. This is well worth doing but be aware that power flushes can be risky. In older heating systems, they can damage joints and older pipework and even end up doing more harm than good. Have a conversation with your engineer to make sure your system can cope before you agree to this.

When you get a quote for your boiler installation, you should ensure that it is an itemised quote. This is because some installers may include extras like this as part of their quote while others will try and charge for them on top.

When you consider a quote it is important to know whether this sort of thing is or isn’t included. If your installer suggests any other possible extras, check what they are, how they help, and whether you really need them before agreeing to pay for them. If you have any questions, you can leave them below and we will do our best to answer them.
