Best Boiler Deals & New Boiler Offers UK Guide

Last updated: November 15, 2023

Are you wondering where to get a good deal on a new gas combi boiler? And what exactly you should be avoiding? Here we explain exactly who is offering the best deals right now.

A new boiler is an expensive investment and sadly there’s no escaping that fact, but there are certainly ways to avoid additional expenses.

In this guide, we’ll explain exactly what to look for and which companies and types of boiler deals to avoid.

Best Boiler Deals in 2022

First things first, when analysing all of the current boiler deals, we have considered the following questions that all boiler consumers should be asking:

  • Is the new boiler quote offered a fixed price or not? I.e. is that the final price without any hidden extras?
  • Does the boiler installation company offer aftercare & support?
  • Does the boiler company in question have a good reputation and reviews?
  • Are they offering reliable boilers, from reliable boiler brands?
  • How long is the boiler warranty they offer and what is included?

Who is Offering the Best Boiler Deals in 2022?

Overall, we have found that the best boiler deals can most often be found with online boiler installation company Heatable, followed closely by Boxt.

How did we come to this conclusion?

  • They offer a fixed price quote.
  • They offer award winning boiler brands.
  • They offer the cheapest boiler prices compared to other notable companies.
  • Their aftercare and customer support are amazing.

Which boiler installation companies offer the best warranty length?

As mentioned, you want the warranty to be as long as possible, since this will mean that you are protected from paying for repair costs and call out charges for as long as the warranty period is valid.

Warranty length is also a sign of boiler quality, just remember that there are conditions of cover, which includes an annual boiler service and registering your boiler with 30 days of installation.

Most of the gas boiler installation platforms you are familiar with offer their boilers with a 10 years manufacturers warranty, while some offer 12 years, with the additional 2 years being provided by themselves.

Just be weary of these additional coverage periods offered by the boiler platforms and not the manufacturer’s, as some people have concerns about the longevity of the boiler companies vs the manufacturers.

Do all boiler installers offer boiler cover?

Not all boiler installers do offer boiler cover, which isn’t a big issue, since you can easily take out a separate insurance package with a third party provider.

The boiler installation companies that do offer both boiler installation and boiler cover includes British Gas, Boxt and Boiler Central.

Bear in mind that boiler cover itself is disputed as being worth it from a financial perspective, so the real question is, does it even matter?

For example, the UK’s consumer organisation Which? found that boiler cover is less cost-effective than simply paying for the repairs as they occur.

Best boiler installation companies offer a workmanship warranty

One of the biggest advantages of using an online boiler platform with a reputation to maintain is that they really care about customer reviews and feedback.

That’s why the majority offer a workmanship warranty for at least 12 months.

This means that if you do experience any issues with your new boiler within the first year e.g. a leak, they will come and fix it free of charge (to avoid those negative reviews).

When comparing all of the biggest gas boiler installers in the UK market, we found all provided a workmanship warranty (as of March 2022).

Are the boiler installers qualified?

We hope so! And according to our checks they all are.

As you may or may not know, in order to install or repair a gas boiler in the UK, the engineer must be registered with the Gas Safe register.

All online boiler platforms provide registration details e.g. a gas safe number, but you can always ask for this on the day of install for your peace of mind.

Just ask to see their Gas Safe ID card. Every Gas Safe installer holds one of these cards and you should look out for:

  • The photo of the engineer.
  • The expiry date.
  • A licence number (should be 7 digits long).
  • A security hologram.
  • Name of their employer.
  • The gas appliances they’re qualified to work on (make sure it says gas boiler).

Gas boiler installation companies with the best customer reviews

One of the most reliable ways to gage the quality of the services offered by a boiler installation companies is to check their customer reviews, which is easy to do thanks to review platforms like Trust pilot.

As of march 2022, the boiler installer with the best overall trust pilot score was Boxt, who have over 10,000 reviews with an average score of 4.9 out of 5.

The other platforms also have pretty impressive average reviews, however, the industry leader has a surprisingly low score, indicating that it may be better to go with a newcomer when it concerns a new boiler.

Do they offer next day installation?

Are you looking for a urgent boiler install? If so next day boiler installation is probably quite important.

Currently, all boiler installer platforms do advertise that they offer next day installation, but during our checks, we discovered the majority have very little availability for next day installs.

With that in mind, we would always advise booking your new boiler install well in advance.

What size boiler is right for your home? If you are thinking about a combi boiler, it is largely determined by the number of radiators in your home.

Do they offer radiators and hot water storage cylinders?

Do you only need a new boiler replacement? Or do you need your complete central heating system replaced? If so, this is where you may want to consider the provider you choose more carefully.

Not all boiler installation companies offer comprehensive options and some only offer new boilers.

BOXT and British Gas offer boilers, radiators and water storage tanks, so these are probably the best options if you need a complete central heating system replacement.

How much is a new boiler installation?

The cost of a new boiler depends, which is not what most people want to hear but it is the reality.

Here are the various different factors that come into the consideration of any boiler quote:

  • The type of boiler e.g. combi boiler, system or heat only.
  • The brand of the boiler.
  • The warranty length that comes with the boiler.
  • If you want the boiler moving to a new location in your property.
  • The location of the boiler e.g. in some cases scaffolding may be required, which can increase the price.
  • Any extras e.g. radiator’s, pipework, a power flush or thermostats.
  • Whether it’s an emergency call-out or not.
