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 at a glance

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.

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.

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.

The installation process

Heatable’s install workflow for a typical like-for-like swap:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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 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.

Pros and cons

Who Heatable is for

Heatable is the right pick if you:

• Need broader credit acceptance for finance approval (the multi-lender panel is genuinely the differentiator)
• Value Which? Trusted Trader accreditation as an independent trust signal
• Are buying a Vaillant or Ideal boiler where Heatable headline pricing is often most competitive
• Want the option to save a quote and decide later rather than committing immediately
• Appreciate the slightly more approachable customer-facing brand voice over BOXT’s operational tone
• Want an FCA-regulated single entity handling quote, finance broking, and install coordination

Consider BOXT or a local engineer if you:

• Qualify for 0% APR and want the longest 0% finance term available (BOXT’s 60 months beats Heatable’s 48 months)
• Specifically want a Worcester Bosch boiler (BOXT’s shareholder relationship delivers better Worcester pricing)
• Live in Northern Ireland (neither Heatable nor BOXT cover NI)
• Live in a rural area where BOXT’s larger engineer network provides better availability
• Want the largest Trustpilot dataset for maximum confidence in the social proof signal

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.
