BOXT: A Trusted Name in Boilers

BOXT is a UK-based boiler replacement company that is dedicated to saving homeowners and landlords both time and money. One of the company’s key innovations was to bring the boiler purchasing process online. They developed a platform where customers could easily select and purchase a new boiler from the comfort of their homes.

Its founders, Mel Butler, Alan Dickinson, Andy Kerr and Keith Jones, launched the online business in 2017, with a view to revolutionising boiler installation services in the UK by introducing ‘smart home installation.’ In 2019, BOXT teamed up with Google by utilising its Google Nest Learning Thermostat and Google Home Mini to provide UK homeowners with voice-controlled heating as standard.

BOXT was among the first to focus on smart boilers, which can be controlled remotely via mobile apps. This emphasis on technology and convenience resonated with customers looking for more control over their heating systems.

The brand uses the internet at its shop front, allowing customers to not only cut out the salesperson but also order a new boiler online for next-day delivery and installation. This is a significant departure from the traditional timeline for boiler installations, which could take weeks. BOXT’s streamlined process allows for quick and efficient installations, often within 24 hours of purchase.

Despite being a relatively young company, BOXT quickly gained recognition for its innovative approach. They won awards such as the “Best Heating and Cooling Installer” at the TechRadar Mobile Choice Consumer Awards, showcasing their impact on the industry.

As the only business to offer UK householders this type of hassle-free service, BOXT is now the top-rated boiler installation company on Trustpilot. You may also be interested to know that three of the UK’s leading boiler manufacturers Worcester Bosch, Vaillant, and Ideal are minority shareholders in BOXT Limited.

Considerations when buying a BOXT Boiler

BOXT appears to be one of the brightest shining lights for installing a new energy-efficient gas boiler. The selection of boilers they offer are all top brands and the company also helps you to choose a boiler from the comfort of your own. But because you are pretty much flying solo, make a note of the key considerations below when selecting the right boiler for your home. 

Energy-Efficiency

Energy efficiency is an important consideration both for the environment and your wallet. BOXT offers a range of energy-efficient boilers with varying efficiency ratings (usually indicated by ErP ratings). Higher-efficiency boilers can help reduce your carbon footprint and lower your energy bills over time. An ErP rating of 92-94% is standard. 

Although BOXT does not manufacture its energy-efficient boilers, the company offers a selection of highly energy-efficient boilers from recognised manufacturers including Worcestor-Bosch, Baxi, Daikin and Vaillant. You can’t go wrong with any of these brands. Navien boilers are also available but are not well-received by UK homeowners.

A range of boiler types, including combi boilers, system boilers, and regular boilers are available and BOXT recommends the type that is best suited for your home based on the information you enter in the online questionnaire. 

In addition, BOXT specializes in smart boilers that can be controlled remotely using apps on smartphones or tablets. This allows homeowners to adjust their heating schedules, monitor energy usage, and even troubleshoot issues without needing to be at home.

Dimensions

Most boilers on the UK market are small and compact and can easily be installed in a tight space such as a kitchen cupboard. If you are pressed for space, a combi boiler will be the best option because you don’t need additional storage space for cylinders and water tanks as you do with system and heat-only boilers. 

Performance Output in kW

The performance output of the boiler, measured in Kw (kilowatt) is crucial for ensuring it can meet your home’s heating demands. A boiler that’s too small may struggle to heat your home effectively, while one that’s too large could be inefficient. BOXT provides guidance on selecting the right size boiler based on factors like the number of bedrooms and bathrooms in your home.

Ease and Cost of Installation

BOXT offers next-day installation in many cases, which is significantly faster than traditional boiler installation services. This quick turnaround time has been appealing to customers who need their heating systems up and running promptly. 

The Leeds-based company also scores better on price comparison tests, although don’t take our word on that. We performed several online price checks with boiler brands, but you may be able to get a better price by using our ‘get a quote’  feature which puts you in touch with the local suppliers that can offer competitive pricing.

Warranty

All gas boilers from BOXT are backed by a parts and labour manufacturer warranty, which can be up to 10 years depending on the length of cover you choose at the time of purchase. BOXT will activate the warranty for you, meaning you’ll be covered from the moment your new boiler is installed.

BOXT Combi Boilers: Compact, Efficient, and Cost-Saving

One of the primary advantages of combi boilers is their compact size. Unlike system boilers that require an additional water cylinder and traditional heat-only boilers, which require separate tanks for hot water storage, combi boilers integrate both heating and hot water functions into a single unit. This space-saving design is particularly beneficial for homes with limited space.

Combi boilers also deliver hot water on demand but can run out if the boiler does not have a sufficient kW output to meet your hot water demands. These boilers do, however, provide excellent water pressure, making them suitable for homes with multiple bathrooms. Because the water is heated as it’s used, you won’t experience a drop in pressure if two showers are running simultaneously.

Installing a combi boiler is often simpler and quicker than installing a traditional boiler with separate tanks. This can result in lower installation costs and less disruption to your home during the installation process.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

BOXT System Boilers: Easy installation, efficient heating, and customisable options

System boilers work by heating water from the mains and storing it in a cylinder until it’s needed. This means you have a steady supply of hot water ready to go at all times without any drop in temperature or pressure if you run the tap whilst someone is using the shower at the same time. 

In addition, system boilers tend to be quieter than combi boilers because they have fewer moving parts. 

System boilers are compact, and whilst they require additional space to install a hot water cylinder, they don’t need a cold-water tank in the loft like heat-only boilers. This saves space and makes system boilers a good option for homes where space is limited.

Some system boilers from BOXT are compatible with renewable energy sources such as solar thermal panels. They can work in conjunction with these systems to further reduce energy consumption and lower carbon emissions.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

BOXT Heat Only Boilers: Versatility, Efficiency, and Reliability

Heat-only boilers are the oldest and most traditional types of boilers found in older UK households. Unlike combi and system boilers, heat-only boilers require a separate hot water cylinder so are only suitable for houses or large apartments that have suitable storage space. 

The advantage of heat-only boilers is they can service homes and buildings with high hot water demands and remain constant even when multiple taps are running. 

 Like system boilers, heat-only boilers can be compatible with renewable energy sources such as solar thermal panels. They can work alongside these systems to further reduce energy consumption and lower carbon emissions.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

Living with your BOXT boiler

BOXT Boiler Warranties

BOXT partners with leading boiler manufacturers such as Worcester Bosch, Vaillant, Baxi and Daikin. The warranties on these boilers are typically 7-10 years as standard, which BOXT passes on to their customers. The length and coverage of the manufacturer’s warranty can vary depending on the specific boiler model. Extended Warranty options are available in addition to the standard manufacturer’s warranty. 

It’s important to register your boiler with the manufacturer to activate the warranty. BOXT provide instructions for this so read them carefully. Most boiler brands insist that a boiler warranty is registered within 30 days of being installed for it to remain valid. 

Some warranties only maintain their validity if your boiler has undergone annual servicing and maintenance by a Gas Safe registered engineer. BOXT offers service plans or reminders to help customers stay on top of their boiler maintenance.

BOXT Boiler Controls

BOXT positions itself as a leading smart-home installation provider – so as you might expect, the boilers they offer feature smart controls. You can also operate your boiler and adjust the settings using the voice activation feature on the Google Home Mini. 

BOXT provides various smart thermostat options that allow homeowners to control their heating remotely via smartphone apps or through voice commands. You can set heating schedules to match your routine, ensuring comfort when you need it, track your energy usage and make adjustments to save on heating costs.

Some boiler controls offer weather compensation features, adjusting the boiler’s output based on the outside temperature to maintain consistent indoor comfort.

BOXT Boiler Cover and Breakdown Options

BOXT offers three boiler cover and breakdown options to provide homeowners with peace of mind in case of unexpected issues with their heating systems. The standard protection for your boiler and central heating system starts for as little as £8.99 per month and does not include excess fees and call-out charges. 

What you do get is unlimited call-outs, all parts and labour costs, access to a 24/7 helpline, annual boiler service and priority response times for emergencies.

BOXT Boiler Surveys and Reviews

It’s fair to say that TrustPilot is one of the most used and reliable sources for researching products on the internet. BOXT is turning in an impressive performance and currently boasts a rating of 4.9 out of 5 from over 27,500 reviews. That’s a good cohort of customers to make a judgment call. In addition, BOXT claims that 30% of their customers leave a review which is a testament to the level of customer service and ease of access to energy-efficient boiler installations. 

Ninety-six per cent of respondents left a 5-star rating, most of whom praise the excellent customer service and fast turnaround. Moreover, the gas-safe engineers are also adept with smart technology and attend calls if Google Nest or Google Mini is the reason why your boiler is not functioning properly. 

However, the customer service doesn’t get it right every time with one per cent complaining about a botched job and non-existent customer service. This is unfortunately a common problem in the heating industry, but it does appear as though BOXT deliver a better performance than most of their competitors.

BOXT doesn’t feature in the Which? survey as that only rates boiler manufacturers, but we did manage to source what appear to be first-hand installation reviews on online magazines like Real Homes. The magazine may be called real homes but we don’t guarantee they are real reviews. The BOXT article is written by the editor-in-chief of another online magazine which means the article is likely to be a sponsored post.

Trusted Reviews also provides a glowing report on a “real-life” installation experience from BOXT. Again, we confirm that Trusted Reviews can be trusted but both the reports mentioned above do seem consistent with the real customer reviews left on TrustPilot, even if the writers have been paid to write a review.

How do BOXT boilers compare with other boiler brands?

BOXT is an online heating company that offers UK homeowners a range of energy-efficient boilers from hand-picked brands. Other companies that offer a similar service are Heatable, iHeat and Warmzilla. 

Together with Heatable, BOXT is recognised as a leader in the UK market. After all, they were the first company to offer online boilers and installation services so it has the experience and know-how to perfect its business model. 

BOXT has certainly teamed up with some of the best boiler brands on the UK market and provides top-notch customer service. The only company that can compete with BOXT is Heatable which offers a 12-year warranty which trumps the 10-year warranty on the premium boilers at BOXT. 

Heatable also offers  4-years 0% interest which BOXT cannot match. If you want to pay instalments with BOXT, there is a 9.9% interest. That said the Heatable deal is only on selected boilers which are considerably more expensive. 

In terms of customer service and speed of installation, there is nothing between the two leaders. Both BOXT and Heatable have online platforms where customers can easily browse and select a boiler based on their needs. BOXT provide next-day delivery, whereas Heatable typically takes 2-3 days before installation takes place. 

Boiler Prices Verdict on the BOXT Boilers: 5/5

With competitive pricing and next-day installation options, BOXT’s use of online orders and local installers ensures that homeowners can replace a broken boiler with a new energy-efficient boiler quickly. In the cold of winter, you don’t want to be waiting 2 or 3 weeks before the replacement boiler arrives. 

BOXT also gives you access to leading boiler brands that manufacture reliable, durable and energy-efficient boilers. With a wide range of price points, sizes and performance outputs to choose from, BOXT has options for all types of regular households in the UK. 

We also like the online questionnaire BOXT provides to help customers find the right boiler for their home. And if you’re still unsure, they have a responsive and helpful customer service team that can make recommendations. 

Because BOXT has contracts with leading boiler manufacturers, the warranty lengths are also pretty good. The company offers the same warranty provided by the mother company including extended warranties. 

Judging by the Trustpilot reviews, the customer service is excellent as well, although, like any corporate entity, customer service can be hit and miss. Bear in mind that the warranties only cover certain parts so when you read reviews about warranty scams and useless customer service, it’s usually because the warranty does not cover the broken part of the boiler. We recommend reading the warranty conditions directly from the boiler brand or specifically asking BOXT what the warranty does and does not cover. 

All-in-all, it appears as though BOXT is one of the most reliable companies to install new energy-efficient gas boilers in the UK. 

So, why buy a BOXT boiler? 

Boasting attractively priced boiler replacements, all BOXT boiler prices are fixed and include the boiler, a free filter, installation and high-quality fixtures, fittings and safety attachments. You’ll even get a free Google Nest Smart Thermostat and a Google Mini that allows you to control your heating settings with your voice. These gadgets would cost you a combined sum of around £260 if you wanted to match them with other boilers. 

All gas boilers from BOXT are backed by a parts and labour manufacturer warranty, which can be up to 10 years depending on the length of cover you choose at the time of purchase. BOXT will activate the warranty for you, meaning you’ll be covered from the moment your new boiler is installed. 

BOXT are also one of the least expensive companies around as well. We can’t guarantee they will be more affordable than a local installer and supplier, but you can check that by using our get a quote feature. 

When it comes to paying for your new BOXT boiler, you can choose to either pay in full or in monthly instalments – which start from just £10.97 per month (* this figure could be subject to change if BOXT changes their pricing plan after this article was published, March 24).

If you decide to pay for your new boiler upfront, BOXT accepts a variety of card payments online, such as Visa Debit, American Express and Mastercard. The company uses a secure payment platform which is powered by Divido.

To pay monthly, you’ll need to make an application for credit through BOXT’s payment partner, Divido. You must select ‘Pay Monthly’ at checkout to be taken to the Divido website to apply for credit, which is provided by Shawbrook Bank. The finance package terms and options include:

  • 5 or 10-year credit term at an APR of 9.9%
  • No deposit is required (but you can put down up to 50% of the total price)
  • Early repayments

Once you have been approved for credit by Divido, you’ll be taken back to the BOXT website to complete your order.
