What Should Be Included In Your Home Boiler Deal

Before we jump into the types of new boiler deals on offer, it’s important to understand what should be included.

Itemised Quotes

A quote might look cheap, but that’s not to say it’s offering you fair value for money. So, you’ll want an itemised quote, so you can compare exactly what each installer is offering you.

One boiler installation package will differ from the next.  You’ll want to look at things such as:

  • Boiler filters included in the installation
  • The quality of the brand being used
  • The warranty of the specific boiler
  • Boiler KW output, and therefore, cost
  • Whether or not the company offering the quote is an accredited installer

You can get a fixed boiler price online without putting in any personal details on HEATABLE. They fit Worcester Bosch and Viessmann boilers, cheap as chips.

Boiler Protection

Not all installers will put in place preventive measures to protect your boiler. Limescale (more important in hard water areas) and heating sludge are big problems.

We’d expect as a minimum that your installer will:

  • Hot flush your system to remove loose heating sludge
  • Dose the system with inhibitor
  • Fit a magnetic system filter

For hard water areas, you’ll also want a limescale filter installed; check to see what’s included on each of the boiler deals you’re being offered.

Both these filters protect expensive boiler components, such as the heat exchanger and pump. A blockage can easily form if your boiler isn’t protected from heating sludge and limescale. And, boiler repairs are never cheap.

Stainless steel heat-exchanger

A new pump could cost £250, where as a heat exchanger replacement could be as much as £500! Make sure these preventative measures are put in place to protect your boiler.

Brand & Warranty

You’ll want to stick to leading brands. There are plenty of inferior boiler brands out there. That’s going to allow you to save £100-300 on boiler prices, or around 10% on the full cost of the install.

But, there’s a good reason for that. Cheap brands are usually unreliable. And, even when they’re not, the warranty on offer certainly implies they are. The small additional cost for a reputable branded boiler with a long warranty, is worth a lot more than the £100-300 extra you’ll be paying.

We’d always recommend a minimum of a 5-year warranty from leading brands such as:

  • Ideal Boilers
  • Baxi
  • Vaillant
  • Worcester Bosch
  • Potterton

Another thing to note, is that not all warranties are clear cut; there are bonuses to be had. For instance, Ideal Boilers (Logic & Logic+) come with a long warranty. But, as an added bonus, the heat exchanger comes with a 10-year warranty. That’s piece of mind, considering a replacement could cost up to £500.

Alternatively, HEATABLE offer excellent boiler deals complete with a 10-year warranty. Their prices on Worcester Bosch appliances are among the most competitive. You can use this form to get an on-screen boiler price in less than 2 minutes.

KW Output

Some properties sit on the fence in terms of the KW output boiler that could be fitted. For instance, some smaller properties could use a 24kw, but a 30kw might offer that little extra when there’s high hot water demand.

The difference in price could be £100-150. So, if you’ve got two quotes that are the same price, but one’s offering the equivalent higher KW boiler but the exact same model, that’s better value for money.

And, that’s why most people don’t buy boiler package deals online. Instead, they leave the purchase of the boiler to the engineer. The engineer offering your boiler deal will be able to spec your property correctly, to ensure that the boiler being fitted is powerful enough.

Make sure your new boiler is spec’d correctly. HEATABLE’s 90-second boiler survey ensures you get the right boiler, at a low price.

Final Note

Don’t be afraid to get more than one quote for your boiler replacement deal. You’ve got a tonne of options including:

The more itemised quotes you get, the easier it will be to determine which one’s the best, and not just based on price.

Types Of New Boiler Deals For Your Home

Should You Consider Pay On Completion New Boiler Deals?

Where possible, you’ll get the best new boiler deals by paying on completion.

Even if you don’t have the cash, a small loan is likely to be a better option than getting finance (even when the finance deal is 0% APR, ironically).

Large National Companies

Let’s not name any names, but there’s a good chance you’ve seen multiple national firms offering combi boiler deals, scrappage discounts, and cheap boilers fitted. Typically, we’d expect a national installer to be somewhere in the region of £600-1,200 more expensive than a specialist local company.

Why? It’s like any large brand. National companies have huge marketing budgets that include TV ads, have hundreds or more employees, and therefore, a lot more overheads to cover.

So, regardless of the timely deal they’re offering (£300 off when you scrap your old boiler etc), this is still likely to be one of the most costly ways to get a new boiler fitted.

Local Boiler Installers 

But that’s not to say you SHOULDN’T get a quote from a national installer, or even explore finance options. In fact, it’s always wise to get as many quotes as possible and do as much research as possible.

The more quotes you get, the better you’ll be able to understand the itemised quote on a list of works you’ve been given. And, even when there’s an install on offer for the same price, or cheaper, it will become obvious why.

For instance, 2 installers might be offering a complete install for £2,000 including VAT.

But, do they both include upgraded heating controls, and a magnetic system filter to protect your boiler?

We’d always recommend getting multiple quotes from qualified installers (you can do that here). But, if you’re heading straight for a Worcester, it’s likely the best fixed price boiler deal you’ll get, is from HEATABLE.

What Are The Benefits Of Buying Boilers On Finance?

There’s been an influx of installation companies offering boiler replacement on finance. And, if you’ve not got the cash, it’s not always the worst idea.

Firstly, because if you’ve got an old boiler, you could be saving up to £305 on energy bills, not the mention expensive repair costs. Essentially, a new boiler could actually pay for itself.

Boiler finance deals can range from 0%, to just above 20%. But, it’s not all as simple as it might seem.

Interest Free Finance Boiler Deals

It’s not just the APR percentage being offered that you need to focus your attention on. You REALLY need to be getting multiple itemised replacement quotes, from both those companies offering finance and those that don’t.

For example, a company charging £3,000 for an install most local installers charge £2,000 for, are going to have no problem offering you 0% finance.

But, the better option here would be to go with the more competitive installer and get a short term loan instead.

And, don’t be put off by companies offering a deal with a higher APR. Rather than the APR, look at the “total cost payable”, including the replacement AND the interest.

£17 Per Month Boiler Replacement Deals

Most new boiler deals that incorporate finance will sit in the £15-20 range. £17 per month boiler replacement deals are the most popular right now. And, that seems like a good buy, given that most people’s mobile phone bill is almost twice the price.

But, like 0% boiler finance deals, you’ll want to get multiple quotes, and keep an eye on what the final price paid is. For instance, you might be able to get a better APR deal and a lower monthly repayment, by putting down a small deposit.

Should You Get Boiler Finance?

If possible, we’d always want to get at least 2 quotes for boiler finance deals.

And, if there’s the option, get a quote that doesn’t require finance via a boiler company. Approach companies that require payment on completion, and consider getting a loan, it usually works out much cheaper this way.

Did You Know There’s A Free Boiler Replacement For Pensioners?

If you own your own property, it’s unlikely you’re going to be eligible for a free boiler.

However, there are some Government run schemes that mean for some, that’s the case; particularly for pensioners.

ECO (Energy Company Obligation)

This is the Government scheme in England, Scotland and Wales.

To qualify for a free boiler, you’ll need to be receiving Pension Guarantee Credit and be over 60.

Your property will need to use Gas, Oil or LPG.

Age Concern Free Boiler Replacement Scheme

For those in Northern Ireland, there’s the Age Concern Free Boiler Replacement Scheme.

You’ll be able to receive a Grant of up to £1,000 if you have a household income of £40,000 or less, had a boiler installed over 15 years ago.

Getting Free Boilers

If you’re looking for more details, we’ve already created a detailed guide on getting free boilers for pensioners here.

Which New Boiler Deals Should You Choose For Your Home?

It goes without saying, if you qualify for a free boiler, with no strings attached, that’s where you should be heading.

If you have the option to pay for your boiler replacement on completion of the install, that’s almost always the way to the get the cheapest deals.

Whatever you choose, make sure you get multiple quotes for boiler replacement prices. That could be comparing on finance with a local installer that requires payment on completion, and even large national firms like HEATABLE.

You’ll be surprised how much you can save by simply shopping around. You can grab free boiler replacement quotes here, from multiple installers.

Vetting Your Boiler Installer

As a final note, you’ll want to do a quick background check on your installer.

For those looking for gas combi boilers, the first check is the Gas Safe Register. You can check that your engineer is qualified to fit your boiler on the register here.

And if you’re like me, it’s always wise to check out any online reviews for the company you plan on using. That means searching on the likes of Google, Yell, FaceBook, Yelp, and even Trust Pilot.
