Boiler installation Liverpool

Every ten years or so, there comes a moment when your boiler finally gives up the ghost and you are faced with the ominous task of replacing it.

No-one looks forward to this moment but it is a fact of life. When it comes, we worry about the cost, finding the right installer, getting ripped off, and buying the wrong boiler altogether.

A quick online search will turn up lots of general guides often containing very mixed-quality information. This guide is written exclusively for people in Liverpool and Merseyside.

It has all of the core information you need before buying a new boiler and some useful local tips to help you find the right installer and hopefully save a tidy sum on the cost of your new boiler too.

Buying a Boiler in Liverpool

The City of Liverpool is home to more than 500,000 people, while Merseyside as a whole is home to almost 1.5 million people.

Living in such a large urban conurbation is both a blessing and a curse when it comes to buying a new boiler.

On the one hand, there is no shortage of plumbing outlets and retail options to use when buying your new boiler.

There are plenty of local tradespeople to call on as well, but in Liverpool, as with the rest of the UK, the demand for plumbers and gas engineers far outstrips supply. This means that finding a gas engineer is simple but finding one that is free to do the job is much harder.

Then there is the issue of cost. With heating engineers in high demand, prices can go up and you might find yourself paying far more to get a new boiler installed than you would expect. If you don’t want to take that risk, this is the guide for you.

Who to use to install your new boiler in Liverpool?

The question we get asked most frequently from people living in Liverpool and all over the country is who they should use to install their new boiler.

It’s a tough question to answer because there are a huge number of variables that have to be considered. The most important bit of advice we can give is to get as many quotes as you can.

Most places will suggest you get three quotes but this is really the bare minimum. The more quotes you get, the better understanding of the market costs you will have and the best chance of finding a great deal too.

There are three main types of installation company you can get quotes from and we would suggest trying to get a minimum of one quote from each type to allow you to compare and contrast different prices:

  • National Installation Companies

National installation companies such as British Gas are well-known companies that operate across the UK. You will see them advertised on the TV and in newspapers and many people assume that they are the best choice.

But adverts cost money and this should be a big red flag. National companies have big overheads and these costs are passed on to their customers. That means that national installation companies tend to be the most expensive way of getting a new boiler installed.

This isn’t always the case and they do sometimes have good offers, which is why we advise you to get a quote to see.

  • Local Heating and Gas Installers

We have already discussed the multitude of independent heating engineers that operate in Liverpool and across Merseyside. These will usually be independent traders or small companies and will often undercut a national installer by several hundred pounds.

But beware. While some independent installers are excellent, others will offer a much poorer service. It is therefore vital to check the background of potential installers before going ahead with the work.

Word of mouth is often key here. If you can find three or four former customers you know who had a positive experience, you are probably fine. Make sure not to take a single person’s word for it though.

  • Online Installation Companies

The most recent addition to the boiler installation market has been online installation companies. But despite their youth, these businesses have really shaken things up.

Most online companies have no offices, no marketing budgets, and spend a modest amount on internet advertising. These low overheads mean they are lean businesses that can offer big savings to their customers.

A lot of people would still not think to look online for an installation company when buying a new boiler. When they do, they are often shocked at how much money they can save.

There are a few sites on the market, but our top recommendation is HEATABLE.

What type of boiler to choose?

When you have chosen your preferred installer, they are likely to want to visit your home to size it up for your new boiler. Often they will suggest a suitable boiler for your property. But be aware that this may not be the best and most cost-effective option available.

A lot of installers have preferred makes and models that they prefer to install. Some will have arrangements with wholesalers to get special deals on particular models to increase their cut. Both of these scenarios mean you might not be getting the best boiler for you.

The best way around this is to know what type of boiler you want before inviting an installer around. But how can you know what type of boiler is best?

All properties are different and there are plenty of other factors like budget, fuel-type, and size you need to consider too.

The first thing to think about is fuel. What do you want your boiler to run on? There are various different options available:

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

With Liverpool being a big city and Merseyside a largely urban area, the majority of people will have a mains gas connection to their homes. This is the most affordable type of fuel and also the cheapest type of boiler too so this is what most people will opt for.

Next up is choosing what type of gas boiler you want for your property. There are various different types of boiler available including:

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

Most smaller homes, flats, and apartments will want a combi boiler that generates heat and hot water on demand. If you live in an older or larger property, a regular boiler with a water tank in the roof might be your preferred option.

Compact boilers are a type of combi boiler designed for particularly small homes or those that need the boiler to be kept in a particularly combined space.

System boilers are only really suitable for commercial properties these days so you are unlikely to need one of those.

What size boiler do you need?

Having talked about a compact boiler, you may well assume that boiler size refers to the physical size of the unit you are installing. Actually, it refers to the power capacity of the boiler and this is something it is vital to get right.

If you have a boiler that is too small, it won’t have enough power to heat your radiators and provide enough hot water when you need it.

But, if you choose a boiler that is too big, you will find you are burning fuel unnecessarily and driving your utility bills up unnecessarily.

Choosing the right-sized boiler for your property can be tricky but there are some rough guides we can give you. If you want to be absolutely certain, the best advice is to call out a heating engineer although you might have to pay for their time.

To help you get a broad idea of what size boiler you will need, we have compiled a table averaging out the size of combi boiler different sized properties will need. We have focused on combi boilers since this is what the majority of people in Liverpool are likely to be buying.

Combi boilers come in three main size ranges:

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

Based on these, we can give you a rough estimate of the size of the boiler you will need for your property:

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

We should emphasise that this is an estimate and also based on average hot water consumption. If you use a lot of hot water you might want to opt for a larger boiler.

If you don’t fancy paying for a heating engineer to come out and tell you what sized boiler you need, another option is an online boiler size calculator. There are a few of these around and HEATABLE is one of the best in our view.

Their online form will ask you all the key questions about the size of your home, number of radiators, number of bathrooms, water usage, and so on. It then recommends boilers that are the right size for that property and gives you a fixed price quote for them. Their selection will include a wide range of makes and models and all will be high-quality units.

Liverpool Boiler Replacement: How much does it cost?

The cost of a replacement boiler is difficult to estimate because there are so many different variables involved. We look at the two most common variables in the following sections of this guide.

If we assume that an average-sized Liverpool home is looking to install a 24kW combi gas boiler, we would estimate that you can expect to pay something in the region of £2,000 including the boiler itself and the cost of installation.

It could be less. If you look on HEATABLE right now, there is a high-spec Worcester Bosch boiler available for just £1,700.

If that still seems like too much, consider a finance deal to spread the payments. Alternatively, there are some cheaper boilers available. However, the cheaper the boiler, the lower the quality of the unit and the more likely you will end up spending more on repairs and other unnecessary costs. You will also probably get a painfully short warranty too.

Moving Your Boiler’s Location

If you need to move the location of your boiler, this is likely to drive the price of installing a new boiler up. Depending on where you need to move it and the amount of work involved, it could go up quite substantially.

The quotes we have estimated so far in this guide assume that you will be keeping your boiler in the same location.

A new location means new pipework and is likely to mean a new flue and associated work to either the external walls or the roof of your home.

Material costs and labour costs for work like this will quickly add up and the physical size of your boiler will play a role too. If your new unit is too large for one installer to move on their own, you will need two installers on-site and this means higher labour costs.

On average, we would expect a boiler relocation to add something between £350 and £750 to your overall bill. It is possible that a local engineer or an online installer like HEATABLE will do the job for less, but if it is a big job it could even wind up costing more.

What Extras Do You Need?

Even if you don’t need to move your boiler, you might need to invest in some extras on top of your boiler unit itself. Some installers will throw these items in for free but others will charge you more. This is one of the reasons why you should ensure you get an itemised quote to see what is and isn’t included.

Extras aren’t just little luxuries. They are often useful additions that can help protect your new boiler and extend its lifespan. The extras that are well worth considering include

  • Magnetic filter – A Magnetic Filter collects up any metallic debris that is floating around in your heating system. This debris can develop into sludge and impact your boiler’s performance or even damage components.
  • Scale filter – If you live in a hard water area, a limescale filter is a sensible investment. Limescale build-ups can damage boiler components but a scale filter helps to prevent this and extends the life of your boiler. Liverpool’s water is fairly hard so it is worth getting one of these.
  • Hot / Power Flush – Your engineer is likely to recommend you get a hot flush or a power flush to clean out any debris or sludge that is in the system before installing a new boiler. This is well worth doing but be cautious. Power flushing an older heating system can damage joints and older pipework and end up costing a lot more so they are not always a good idea.

If your boiler engineer recommends any other extras, you should make sure you know what they are and why you need them before agreeing, If you have any questions, just leave them at the bottom of this guide too and we will do our best to answer all of them.
