Heatable is one of the UK’s most established fixed-price online boiler installers, holding Which? Trusted Trader accreditation, FCA-regulated credit broker status (FRN 805259), and a Trustpilot rating of 4.8 stars across more than 14,000 reviews. The pitch is familiar territory for online installer buyers: answer a handful of questions about your home, get a fixed all-in price for boiler plus installation in 90 seconds, and book a next-working-day fit. Where Heatable genuinely differentiates from competitors like BOXT is in its broader credit acceptance (the panel lender network includes prime and subprime providers) and its independent Which? Trusted Trader status.
This review covers what Heatable actually does, the boiler brands they fit and at what price, the finance structure and where it sits versus competitors, the customer experience based on Trustpilot data and our own analysis, and how Heatable compares with BOXT, the other major fixed-price online installer in the same space.

Heatable
Genuinely one of the strongest fixed-price online installers in the UK, with the only Which? Trusted Trader accreditation in the major-online-installer segment, the broadest credit acceptance through a multi-lender panel, and FCA-regulated credit broker status. Particularly strong for buyers with imperfect credit profiles and for Vaillant boilers where headline pricing is often competitive.
What Heatable customers say
★★★★★
4.8 / 5 from 14,000+ reviews
“From start to finish the guys at Heatable were excellent, answering all my questions and reacting to change quickly. The installation partner, B E R Projects LTD were great too. They arrived when they said they would, worked through even in 34-degree heat, and got the whole thing done in just over a day. The entire process was professional and their work exceptional. Thanks Heatable.”
“Good communications throughout from Heatable and the installer Harley of HJ Heating & Plumbing. The units arrived first thing the day prior to installation as agreed and Harley arrived around 8am the following day to install. Everything went reasonably smoothly and the job was complete by 3:30pm. Harley tidied up afterwards and walked us through how the system operated. Good job all round.”
“I can’t say enough good things about Heatable! They took time to help me navigate the minefield, never upselling but always taking opportunities to save me money. They helped me put finance in place, and installed quickly, making some neat adjustments to ensure a good fit. I wanted to cry when my old boiler gave up but everyone I spoke to was extremely knowledgeable and very lovely so the whole process was painless!”

What Heatable actually is
Heatable operates the same fixed-price online boiler installation model as BOXT: a quote tool that generates real installed prices in roughly 90 seconds, no home survey required before quoting, and a national engineer network that fits the boiler typically within 24 hours of confirmed booking. The Heatable Ltd business has been operating in this space for several years, and the platform has built one of the more established alternatives to traditional local-engineer quotes.
What sets Heatable apart from BOXT and other competitors in this segment comes down to three things: independent accreditation (Which? Trusted Trader, which BOXT does not hold), FCA-regulated credit broker status with a multi-lender panel rather than a single finance partner, and a deliberate positioning around credit accessibility. Heatable’s own advertising language explicitly welcomes applicants with imperfect credit histories, which most online installers do not advertise even when they technically accept them.
The brand voice is also worth noting: Heatable leans into “Heat Happy” as their core message, and the marketing tone is more approachable and customer-friendly than the operational-efficiency tone BOXT tends to project. Trivial to most buyers, but a real factor for some who find traditional boiler-buying intimidating.
The fixed-price model
Heatable’s all-in fixed price covers the typical scope you’d expect from a serious online installer:
- The boiler itself, factory-new with manufacturer warranty
- Full Gas Safe-registered installation by a Heatable-approved engineer
- Standard horizontal flue kit
- System filter fitted to the heating circuit
- System flush of the existing pipework
- Removal and disposal of the old boiler
- Manufacturer warranty registration on your behalf
- Gas Safe certificate of completion
- Heatable workmanship guarantee on installation work
Heatable also operates a Save My Quote feature that allows you to lock in a quoted price and decide later, useful if you’re getting comparison quotes from BOXT or a local engineer and don’t want to risk price changes before committing.

- Which? Trusted Trader, 4.8 stars from 14,000+ Trustpilot reviews
The boilers Heatable fits
Heatable carries the five mainstream UK boiler brands. Pricing across the range broadly follows the rest of the market, but headline prices on Vaillant and Ideal installs are often competitive, occasionally undercutting BOXT on identical specifications.
| Worcester Bosch | Premium tier. Heatable fits the Worcester Greenstar 4000 and 8000 ranges. Pricing is competitive but typically not as aggressive as BOXT given BOXT’s direct manufacturer relationship. |
|---|---|
| Vaillant | Strong on Vaillant: headline prices on the ecoFIT Pure and ecoTEC Plus are often the most competitive in the segment. Heatable’s engineer network is Vaillant Advance-qualified. |
| Ideal | Heatable fits the Logic, Logic Max and Vogue MAX ranges. Competitive on Ideal pricing across the board. |
| Baxi | The Baxi 800 Combi is a particularly strong value pick through Heatable, often coming in £100-£200 cheaper than equivalent local installer quotes. |
| Navien | Value-tier Korean brand with strong hot water flow at competitive prices. |
For our independent take on the individual boilers Heatable fits, see our best combi boiler UK guide and the brand-specific reviews (Worcester 4000, Worcester 8000, Vaillant ecoTEC Plus, Vaillant ecoFIT Pure, Ideal Vogue MAX, Baxi 800).
Heatable finance and credit acceptance
Finance is genuinely the most distinctive feature of the Heatable proposition, but not for the reason most reviewers assume. Heatable’s 0% APR window runs 12 to 48 months on selected boilers, which is competitive but actually slightly shorter than BOXT’s 60-month maximum. Where Heatable wins on finance is breadth of acceptance rather than length of term.
Heatable is FCA-regulated as a credit broker (FRN 805259) and operates a panel of lenders that includes both prime and subprime providers. In practice, this means applications that fail a single-lender setup (like BOXT’s HomeServe Finance arrangement) can succeed at Heatable by being routed to a different panel lender appropriate to the credit profile. Heatable explicitly markets “bad credit welcome” applications, which is unusual transparency in this segment.
Heatable’s full finance structure:
| 0% APR (interest-free) | Available on selected boilers, terms 12 to 48 months |
|---|---|
| 11.9% APR (interest-bearing) | Terms 3 to 10 years on most boilers |
| Minimum loan amount | £1,000 |
| Deposit options | £0 deposit available on most plans; larger deposits unlock better APRs |
| Soft search | Available before any hard credit check (your credit file is not affected at quote stage) |
| Credit profile acceptance | Broader than competitors; applications routed across multiple panel lenders by credit profile |
| Lender | Multiple panel lenders (not a single provider) |
| Heatable’s role | FCA-regulated credit broker (FRN 805259), not the lender |
The installation process
Heatable’s install workflow for a typical like-for-like swap:
- Online quote (90 seconds). Heatable’s property questionnaire is slightly longer than BOXT’s, capturing more detail upfront which reduces the chance of in-day surprises. Real fitted prices and finance options appear before you provide contact details.
- Save My Quote (optional). You can save your fixed price and return to it later, which is useful for comparing quotes against BOXT or local engineers.
- Booking and engineer assignment. Heatable confirms install timing and assigns the engineer once you proceed. Next-day install is widely available; Heatable typically installs within 24 hours of confirmed booking.
- Installation day. Like-for-like swap typically takes 4-6 hours. Old boiler removed and disposed of, new boiler fitted, system filter installed, system flush, commissioning checks, demonstration of controls.
- Documentation. Gas Safe certificate issued on completion; Heatable registers the manufacturer warranty within 24 hours.
Heatable’s engineer network is smaller than BOXT’s 15,000-strong panel, which can occasionally mean slightly longer waits for installation slots in rural areas during peak demand (October to February). Urban locations see consistent next-day availability.
Warranty and aftercare
The warranty stack on a Heatable install:
- Manufacturer warranty: Up to 12 years on selected boilers (Vaillant ecoTEC Plus carries 12 years standard; Ideal Vogue MAX qualifies for 10 years through Heatable, 12 years requires a MAX Accredited installer which Heatable’s network may or may not include for a specific install).
- Heatable workmanship guarantee: Covers installation-related issues such as pipe joints, flue fitting and commissioning. Term varies; check your specific quote for the exact length.
- Annual servicing: Heatable offers annual service plans to maintain manufacturer warranty validity. Optional but useful if you don’t want to remember to book it separately each year.
Aftercare is generally well-rated on Trustpilot, with the most common positive theme being responsive customer service. The negative themes are smaller in volume but worth knowing: occasional complaints about communication delays during peak demand periods and some reports of complex install upcharges that weren’t flagged accurately in the quote tool.
Heatable customer reviews and reputation
Heatable’s Trustpilot dataset of 14,000+ reviews at 4.8 stars is genuinely strong, although smaller than BOXT’s 59,000+ reviews. The Which? Trusted Trader accreditation adds an additional independent trust signal that most online installers in this segment don’t carry.
The dominant themes across Heatable reviews are consistent:
- Quote process: customers consistently call out the simplicity and lack of pushy follow-up sales calls. The Save My Quote feature gets specific praise from buyers comparing across multiple installers.
- Finance acceptance: a notable theme in Heatable reviews is customers reporting acceptance for finance after being turned down by competitors. The broader credit acceptance is real and material.
- Engineer professionalism: individual engineers are frequently named and praised by reviewers, suggesting decent recruitment standards across the network.
- Communication: pre-install communication consistently rated highly; engineer arrival windows and timing updates work reliably.
The honest negative themes:
- Complex installs: occasional reports of additional cost flagged at install rather than at quote, more common where pipework needs upgrading or flue runs are non-standard.
- Rural availability: longer install lead times in rural Scotland and Wales during peak demand.
- Dataset size: at 14,000 reviews, Heatable’s data is genuinely robust but less statistically deep than BOXT’s 59,000. The signal is real but the volume is smaller.
Heatable vs BOXT: which to pick
Heatable and BOXT are the two strongest fixed-price online installers in the UK, and they’re genuinely closely matched on the underlying install quality. The differences come down to specific buyer circumstances rather than overall winner.
| Heatable | BOXT | |
|---|---|---|
| Trustpilot | 4.8 stars, 14,000+ reviews | 5 stars, 59,000+ reviews |
| Independent accreditation | Which? Trusted Trader | None (industry partnerships only) |
| FCA credit broker status | Yes (FRN 805259) | Yes (via HomeServe Finance broker setup) |
| Manufacturer backing | Independent | Worcester Bosch minority shareholder |
| Engineer network | National but smaller than BOXT | 15,000+ nationwide |
| Brand range | Worcester, Vaillant, Ideal, Baxi, Navien | Worcester, Vaillant, Ideal, Baxi, Navien |
| Quote speed | ~90 seconds | ~60 seconds |
| Next-day install | In most cases (within 24 hours of confirmed booking) | If ordered by 3pm |
| 0% APR maximum term | 48 months | 60 months |
| Credit acceptance | Broader; multi-lender panel including subprime | Single-lender (HomeServe Finance) |
| Vaillant headline pricing | Often most competitive in segment | Competitive, slightly higher on average |
| Worcester headline pricing | Competitive | Often most competitive (shareholder relationship) |
Heatable is the better pick if:
- You have an imperfect credit profile and want the best chance of finance approval (the multi-lender panel is the genuine differentiator here)
- You specifically value Which? Trusted Trader accreditation as an independent trust signal
- You’re buying a Vaillant or Ideal boiler where Heatable’s headline pricing is often most competitive in the segment
- You want a single FCA-regulated entity handling both the install quote and the finance broking
- You appreciate the Save My Quote feature for genuine comparison shopping
BOXT is the better pick if:
- You qualify for the headline 0% APR rate and want the longest 0% term available (BOXT’s 60-month plan is currently the longest in the segment)
- You’re buying a Worcester Bosch boiler (BOXT’s shareholder relationship delivers the most competitive Worcester pricing)
- You want maximum confidence in the customer dataset (BOXT’s 59,000+ Trustpilot reviews is one of the largest in the category)
- You live somewhere benefiting from the 15,000-strong engineer network (deeper rural coverage)
- You’ll later consider solar, heat pumps, or EV charging from the same installer
In practice, the right move is to quote both in 10 minutes and pick whichever lands the better fitted price and finance option for your specific situation. For our full ranked breakdown of UK boiler finance options across all major providers, see our best boiler finance deals guide.

Frequently asked questions about Heatable
Is Heatable a reputable and legitimate company?
Yes. Heatable is an established, independent UK company, registered at Companies House as Heatable Ltd (company number 08804726), that has operated since 2017 and says it has served more than 40,000 customers. It holds Which? Trusted Trader accreditation, is FCA-regulated as a credit broker (FRN 805259), is MCS certified, and carries a 4.8-star Trustpilot rating across more than 14,000 reviews. Those are strong independent signals that it is a legitimate, reputable installer, though as with any installer it is worth reading recent reviews and confirming exactly what your quote includes.
Is Heatable better than BOXT?
Neither is outright better; it depends on your circumstances. Both are fixed-price online boiler installers covering England, Scotland and Wales. Heatable holds Which? Trusted Trader accreditation that BOXT lacks, has broader credit acceptance through a multi-lender panel, and is often most competitive on Vaillant and Ideal pricing. BOXT has the longer 0% finance term (60 months vs Heatable’s 48), a larger Trustpilot dataset, and Worcester Bosch as a minority shareholder, which tends to make its Worcester pricing keener. For most buyers, quoting both takes about 10 minutes.
Are iHeat and Heatable the same company?
No. iHeat and Heatable are two separate, independent companies. Both are UK online fixed-price boiler installers that run a similar quote-online, install-fast model, which is why they are often compared, but they have different owners and are not connected. iHeat trades under Leads UK Ltd, while Heatable is Heatable Ltd (Companies House number 08804726).
How much does a Heatable boiler installation cost?
Heatable’s entry-tier fitted price starts at around £1,895. Typical mainstream fitted prices run from around £2,000 for an Ideal Logic Combi to around £2,800 for a Worcester Greenstar 8000. The fixed price includes the boiler, full installation, flue, system flush, system filter, controls, warranty registration, removal of the old boiler, and a workmanship guarantee.
Does Heatable offer 0% finance?
Yes. Heatable offers 0% APR boiler finance on selected boilers across terms of 12 to 48 months. Interest-bearing plans at 11.9% APR are available for 3 to 10 year terms. The minimum loan amount is £1,000. Heatable is an FCA-regulated credit broker (FRN 805259) introducing applications to a panel of lenders, not the lender itself.
Can I get Heatable finance with bad credit?
Heatable explicitly accepts applications from buyers with imperfect credit profiles. The multi-lender panel includes both prime and subprime providers, meaning applications routed through Heatable have broader acceptance than single-lender competitors like BOXT. Heatable also offers a soft search before any hard credit check, so your credit file is not affected at quote stage.
Does Heatable have a discount code?
Heatable’s model is a single fixed online price rather than public discount codes, and it runs a price-match guarantee that matches any like-for-like cheaper quote, so the quoted price is meant to be the best price without a code. Heatable itself warns that many websites advertising ‘Heatable discount codes’ are fake, so treat code sites with caution. The genuine ways to lower your cost are the price-match guarantee and comparing finance terms inside the quote.
What boiler brands does Heatable fit?
Heatable installs the five mainstream UK boiler brands: Worcester Bosch, Vaillant, Ideal, Baxi and Navien. Headline pricing is often most competitive on Vaillant and Ideal installs, where Heatable frequently undercuts other major online installers.
Do Heatable do heat pumps?
Yes. As well as boilers, Heatable installs air source heat pumps and is MCS certified, which means eligible homes can claim the government’s £7,500 Boiler Upgrade Scheme grant, applied for on your behalf. Heat pumps are best suited to well-insulated homes and are quoted through the same fixed-price online process as boilers.
Does Heatable install solar panels and batteries?
Yes. Heatable installs solar panels, battery storage and EV chargers alongside boilers and heat pumps, and is a Tesla-certified Powerwall installer. Its solar and battery installations are MCS certified, which is required to access the Smart Export Guarantee for payments on the electricity you export.
What is the warranty on a Heatable boiler?
It depends on the boiler. Heatable fits boilers with manufacturer warranties of up to 12 years on selected models (for example, the Vaillant ecoTEC Plus), with the exact length shown against each boiler in the quote. On top of that, every Heatable installation includes 12 months of Heatable workmanship protection covering the installation work itself. Keeping up annual servicing is usually required to keep the manufacturer warranty valid.
How long does a Heatable installation take?
A typical like-for-like boiler swap takes 4 to 6 hours on the day, completed by a single Gas Safe-registered engineer. Conversions (system to combi, or regular to combi) take longer, typically a full day. Heatable typically installs within 24 hours of confirmed booking, subject to engineer availability.
Is Heatable Which? Trusted Trader?
Yes. Heatable holds Which? Trusted Trader accreditation, which requires passing an independent assessment of trading practices and service standards. Heatable is currently the only major fixed-price online boiler installer with this accreditation in the UK.
Does Heatable cover Northern Ireland?
No. Heatable covers England, Scotland and Wales. Northern Ireland customers need to use a local Gas Safe-registered engineer instead. The same coverage limitation applies to BOXT.
Who owns Heatable?
Heatable is a family-owned and run UK company, registered at Companies House as Heatable Ltd (company number 08804726). It has operated in the online boiler installation market since 2017 and says it has served more than 40,000 customers, and it remains independent rather than being part of a larger energy group.
Final verdict
Heatable is one of the two strongest fixed-price online boiler installers in the UK, alongside BOXT, and is the right pick for a specific kind of buyer. The Which? Trusted Trader accreditation is a genuine independent trust signal that BOXT doesn’t carry. The multi-lender panel and broader credit acceptance is real and material for any buyer who has been turned down for finance elsewhere. And the headline pricing on Vaillant and Ideal installs is often genuinely the most competitive in the segment.
The honest concession is that BOXT is genuinely close on overall install quality. The Worcester Bosch shareholder relationship gives BOXT more competitive Worcester pricing, the 60-month 0% APR term beats Heatable’s 48 months on the longest 0% window, and the larger engineer network and Trustpilot dataset give BOXT a slight edge on the basic operational metrics.
For most buyers, the right move is to quote both Heatable and BOXT in 10 minutes total and compare. The specific quote for your home will swing one way or the other depending on boiler, location, and current promotional pricing. For buyers with imperfect credit profiles, Which?-focused buyers, or Vaillant-specific shopping, Heatable is the clear pick. For Worcester buyers and buyers wanting the longest 0% term, BOXT is the clear pick.
