Should I get multiple quotes before installing a new boiler in Milton Keynes? 

If it’s not an urgent matter — i.e. your boiler’s not busted in the midst of a week-long cold snap — then YES. You should certainly take the time and review as many quotes as possible. Casting a wide-enough net by soliciting estimates from multiple installers will familiarise you with the local market rates in Milton Keynes. And, you’ll have a far better chance of finding a great deal.

While you do your research, you’ll primarily run into 3 different types of installers:

  • National installation companies
  • Local heating and gas installers, and
  • Online installation companies

As we mentioned above, an online installation company will provide the fastest quote (you can even get one now in a separate browser tab, if you like), and likely get your new boiler installed the soonest. That said, to be diligent, you should solicit estimates from all the other installers out there.

Now, let’s briefly review the pros and cons of each installer type.

National Installation Companies

Think British Gas. These guys operate all over the UK and get stellar prices from their suppliers. Alas, you won’t see the savings — these companies’ monstrous overheads are inevitably passed on to you, the consumer, so you end up paying a premium. And don’t be naive thinking that as an existing British Gas or E.ON customer you’ll get rewarded for your loyalty — their sweetest deals are typically reserved for new customers.

That being said, you may be lucky enough to come across a bargain, so do check anyway. Most of these large companies offer fixed online quotes, which means you have nothing to lose.

Local Heating and Gas Installers

Your local installers will generally quote you lower than their national counterparts. That said, you may come across a gap in pricing, with more reputable firms charging a hefty premium and the little guys offering substantial discounts. Low prices may be tempting, but quality can be an issue with these small-scale installers. To avoid further costs stemming from shoddy workmanship, be sure to research smaller installers thoroughly and review their quote before making your decision.

Another thing to note about local installers, is that most of them won’t offer you a quick, instant quote. So, if you want to go this route, be prepared to make time for an appointment at which the installer will be able to assess your needs and quote you.

Online Installation Companies

While online companies are relatively new in the UK market, they do offer nationwide coverage, and tend to move quickly with both quoting and installing your new boiler. Some have established partnerships with top-grade boiler companies, so they’re able to offer incredible deals. Unlike British Gas et al, online installation companies have a small overhead, so they’re able to pass the savings on to their consumers. Best of all, they can quote you quickly, and get your new boiler humming along in as little as a day.

While there are several online boiler installation companies, Heatable is currently the best option because of the awesome deals it gets from Worcester Bosch. You can see the savings for yourself — just fill in this quick survey and you’ll get a fixed quote on your screen in minutes. In fact, Heatable will guarantee the price for the range of boiler models that are suitable for your property. If you’re happy with the estimate, you should be able to get your new boiler installed the very next day.


How to Pick the Right Boiler For Your Milton Keynes Home

Apart from choosing an installer, you’ll also need to zero in on the boiler make and model. There are several basic selection criteria:

  • Fuel type — gas, LPG, oil, electricity, renewable sources?
  • Boiler type — combi, regular, systems, or compact boiler?
  • Boiler size (in kilowatts)

You’ll also have to consider the price, any financing schemes you may want to pursue to alleviate the burden of a large, upfront purchase, and the boiler’s warranty period. But it’s important to get an idea of what your preferred models are based on the criteria above. If you leave it to an installer to select the optimal boiler for you, chances are they’ll stick you with their preferred boiler model. Installers’ deals with boiler manufacturers are often structured to help the former boost their profit margin; for the customers, these business arrangements may translate into getting stuck with an unsuitable boiler model.

Once you’ve done your own research and narrowed down your boiler’s type, fuel, and size, a company like Heatable can show you an assortment of models and financing options, so you can arrive at your own, educated decision.

What fuel will you use?

First, you need to know the type of fuel your boiler uses. There are various different options available:

  • Gas — most cost-efficient, relatively “green”, but requires mains gas
  • LPG — great for off-grid regions, fairly sustainable, but entails changing gas tanks
  • Oil — “dirty” compared to other fuels, but a suitable option for areas off the gas grid
  • Electricity — most expensive way to heat; possibly sustainable depending on your energy supplier
  • Renewable energy sources — may help you access funds from government grants, but typically require you to spend large sums upfront

Natural gas is the most cost-efficient option of the ones listed here, and one of the more sustainable, too. Since Milton Keynes is on the mains gas grid, you’ll have no trouble getting a gas boiler. Opting for a gas boiler will also give you the widest assortment of boiler models from which to choose.

Which gas boiler system is right for you?

Assuming you’re opting for gas as your fuel, the next question is what type of gas boiler you want to choose. Again, there are various different types available including:

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

For the majority of people in the Milton Keynes area, who live in a smaller house, a flat, or an apartment, a combi boiler will be the best choice. That’s because these devices have a relatively small footprint, and are thus easy to install somewhere out of sight — even in smaller living quarters. Combi boilers are also quite efficient, as they supply hot water on demand. The downside to combis is that they struggle to meet the hot water demands of large, busy families.

So, if your household goes through lots of hot water, or if you already have a water tank and an airing cupboard, a regular boiler may be the more logical alternative.

System boilers are usually fitted in commercial properties these days and a compact boiler is only necessary if you live in a very small property and need to fit a combi boiler in a very tight space.

What size boiler do you need?

When we talk about boiler size, we are referring to the heat output of your new boiler rather than its physical size. It is an important thing to get right.

If you buy a boiler that is too small, it will struggle to provide sufficient hot water or to get your radiators up to the desired temperature. Conversely, if you buy one that is too big, you will see your utility bills going up and up without any obvious benefit.

Getting the right size of boiler is therefore crucial, but it isn’t easy. A lot of people will leave this to their installer too. But it is well-worth understanding what size boiler you need in your property to ensure that the one you end up with is appropriate for your property.

Estimating boiler size for your home

Combi boilers come in 3 principal size ranges. Your home’s size, as well as the number of radiators and bathrooms determine which size range is the most suitable:

Boiler SizeRadiatorsBathroomsBoiler Size
24kW-27kW10 or fewer1Apartments, 1 & 2 bed houses
28kW-34kW10-152Medium size 2-4 bed homes
35kW-42kW15-202+Larger Properties

If you want some more precise recommendations and don’t fancy waiting for your installer to visit and the potential cost of a call out, you can always try an online boiler size calculator like the one Heatable has on its website. You don’t need to share any personal info — just some property metrics needed to calculate the boiler size. You’ll get an instant result with a list of boilers best suited for your property.

Milton Keynes boiler replacement: How much does it cost?

The key matter for most readers will be just how much your replacement boiler is likely to cost. This is a complicated calculation too, because there are a lot of different factors that can affect the bill.

We will have to make a few assumptions. First, we assume that you live in an average-sized Milton Keynes property and are looking to install a 24kW combi gas boiler. We will also assume that you use an average amount of hot water.

On that basis, the cost for a replacement boiler is likely to be in the region of £2,000.

You could spend less if you shop around. On Heatable right now, there is an excellent Worcester Bosch combi boiler from just £1,785.

You could spend more if you want to. There are plenty of more expensive boilers on the market too. You can also find boilers that are cheaper but be wary of these. They are frequently made with cheap components and offer short warranties. This inevitably means they will deteriorate sooner rather than later and in the long run, the total cost of keeping this type of boiler running is likely to outweigh any upfront savings you might make.

Moving Your Boiler

A big factor in the overall cost of your new boiler is likely to be whether or not you need to move it. Installing a replacement boiler is a fairly straightforward job on its own and should take no more than a day. But if you are moving it to another place on your property, it is a different story and the price can start to stack up.

Moving a boiler means you need new pipework, a new flue and any associated work on your external walls or your roof. You may well also need decorative work inside your property. All of this adds up, with labour costs and materials all needing to be taken into consideration.

On average, if you are looking to move a boiler in Milton Keynes or the surrounding area, you can expect it to add something in the region of £350 – £750 onto your bill.

It is possible that a local engineer or an online installation firm like Heatable might be able to do the job for less. But equally, if your boiler move is a major one, it could cost even more.

What Extras Do You Need?

The other big factor in the size of your overall bill for a replacement boiler is likely to be extras.

There are plenty of extras that can come with a new boiler. But some installers will include them in their quote while others will try to add the cost on. You don’t want to fall into a trap here so be sure to request an itemised quote every time.

It is understandable why you might think extras are unnecessary but in actual fact, some extras are very worth getting and can extend the lifespan of your new boiler.

Three extras that definitely well worth investing in are:

  • Magnetic filter

A magnetic filter fits into your new boiler and hoovers up any metallic debris that is floating around. This debris can create sludge which clogs up your boiler, affect performance, and even damage components. It is well worth getting a magnetic filter installed but be sure to get it cleaned every year as part of your boiler service.

  • Scale filter

Milton Keynes is slap bang in the middle of a very hard water area and this means that limescale can be a big problem. It can build up on your boiler components and damage them or even stop your boiler from working altogether. A scale filter can help to prevent these limescale build-ups and, in the long run, it can reduce repair bills and extend the life of your boiler. Highly recommended in Milton Keynes.

  • Hot / Power Flush

If you have an older heating system, it is likely to have some sludge and debris in it. A hot flush or a power flush is a simple way to clear all this sludge out and help your boiler to perform at its peak. Just be aware that power flushes can be risky with older systems. They are very strong and can damage joints and older pipework. Have a discussion with your installer before proceeding and make sure your central heating system can cope with a power flush before going ahead.
