Heatable vs Boxt: How to Choose the Right Online Boiler Installer

This guide is designed to be fair, practical, and genuinely useful.

We’ll run through where the services are broadly similar, where the differences actually matter, and the key checks to make before you commit.

Ultimately, the “best” option usually comes down to your home, your timeline, and what you care about most (not the logo on the van).

🔑 Key points - Heatable vs BOXT:

• Both offer online fixed-price quotes - the final price depends on your inputs and photos

• Price - no consistent winner - compare like-for-like (same boiler, warranty, controls, extras, install type)

• Speed - next-day can be possible - but postcode, stock, job complexity and T&Cs decide it

• Aftercare - compare how issues are raised and who handles faults (installer vs manufacturer)

• Warranties - “up to 10–12 years” are usually manufacturer warranties with conditions - workmanship cover is separate

• Plans/finance - compare total cost and what’s included (service, repairs, fees, exit terms) - not the monthly figure

Heatable vs Boxt Comparison Table:

[1] The quoting experience - how “fixed” is fixed?

Both Heatable and BOXT are built around the same idea - get a price online without the hassle of multiple home visits (typical of more traditional companies, like British Gas).

That’s genuinely helpful - but here’s the reality:

• An online quote is only as accurate as the info you provide (boiler location, flue route, condensate run, gas pipe size, access, number of bathrooms, etc.).

• If anything’s missing or unclear, either provider may need more detail - usually photos - before they can confirm the scope and lock it in.

What to do (whichever you choose):

• Treat the quote journey like a mini-survey - answer accurately, and upload clear photos when asked.

• If your install is even slightly “non-standard” (relocation, awkward flue, long pipe runs, tight access), prioritise the provider that’s most willing to sense-check the job before install day - not the one that’s fastest to take payment.

[2] Price - who’s cheaper?

There isn’t a permanent winner.

The only fair comparison is a like-for-like quote:

• Same boiler brand + model (and same kW output)

• Same warranty length

• Same extras (filter, controls/thermostat, flue kit, powerflush if needed)

• Same install type (straight swap vs relocation)

If one quote comes out much cheaper, double-check what’s included - because price gaps are often caused by differences in scope, not “better deals”.

[3] Speed - can they really do next-day?

Sometimes, yes. Sometimes, no - especially in peak winter, or if your install is even slightly non-standard.

Both Heatable and BOXT offer fast installs (often “next-day” style turnaround), but availability depends on a few very real constraints - engineer capacity in your area, boiler stock, and whether the job is straightforward enough to confirm quickly.

What to check before you choose:

• The earliest available install date for your postcode

• Whether your chosen boiler model is actually in stock for that window

• Whether the provider has properly confirmed the install assumptions (photos are your best friend here)

• Any “next-day” cut-offs and T&Cs (these often matter more than the headline)

[4] Aftercare & support - what happens after install day?

This is where experiences can feel very different - because “aftercare” isn’t one thing.

It’s a mix of:

• how easy it is to raise an issue

• how quickly it’s triaged

• and whether the next step is installer-led or manufacturer-led

What BOXT says - it offers a dedicated app for ongoing support, and highlights a pre- and post-installation audit as standard.

What Heatable shows publicly - there’s a clear “Raise an issue” aftercare route, with contact hours listed for Sales and Engineers.

Smart move (whichever you choose): keep screenshots / copies of:

• what your quote includes (and excludes)

• warranty terms (manufacturer + workmanship)

• commissioning paperwork

• who to contact first if there’s a fault (installer vs manufacturer)

[5] Warranty - the most misunderstood part of boiler buying

Those “up to 10–12 year” warranties you see advertised are usually manufacturer warranties.

They can be brilliant - but they’re almost always conditional.

Always check:

• Is the warranty length tied to using specific controls or add-ons?

• Does it require annual servicing (usually it does)

• Who registers it - you, or the installer?

• What’s covered under manufacturer warranty vs workmanship warranty (they’re not the same thing)

Both BOXT and Heatable register the manufacturer warranty on the customer’s behalf.

[6] Credibility signals - accreditations, reviews, and what they actually prove

This is the bit most comparison pages oversimplify.

“Credible” isn’t a badge - it’s a bundle of signals, and each one proves something different.

Accreditation (what it proves):

Accreditations can be meaningful, but they’re not a guarantee you’ll love your install - they’re proof there’s been some external vetting and standards to meet.

Reviews (how to read them like data):

Reviews are useful - if you treat them like a dataset:

• Look for patterns, not one-off horror stories or “best day ever” raves (communication, punctuality, cleanliness, snagging, aftercare).

• Filter for installs like yours (straight swap vs relocation, tricky flue, long pipe runs, older properties).

• Pay attention to what happens when things go wrong: response times, ownership, and whether issues get resolved without you chasing.

On Trustpilot, review counts are currently in the “tens of thousands” for BOXT and “thousands+” for Heatable - but scores and totals change constantly, so always verify the latest numbers directly on the platform before you use them as proof.

Bottom line:

• Accreditations = a check that some standards and vetting exist.

• Reviews = a window into how the experience tends to go in practice.

Use both - but don’t let either one do all the thinking for you.

[7] Boiler “plans” and monthly payments

If you’re comparing pay-monthly options, don’t just compare the monthly price - compare what’s actually bundled.

Heatable’s monthly plan (what they say it includes)

Heatable offers Heatable One, an all-inclusive plan - a new boiler installed, annual servicing for the term, and unlimited repairs/callouts.

The pricing starts “from £49.99/month” and that the deposit is typically £99.

BOXT’s monthly plans (what they say they include)

BOXT promotes BOXT Life as an all-inclusive boiler plan, and separately advertises a range of finance options - including 0% interest options on selected boilers/terms (subject to status and T&Cs).

What to compare line-by-line (this is the bit that matters):

• Total cost over the full term (not just the headline monthly)

• Exactly what’s included: servicing, repairs, parts, labour

• Any excess / call-out fees (and what triggers them)

• Early exit / cancellation terms and what happens if you move home

• Who handles issues first: installer vs manufacturer (and the process)

So… which should you choose?

Pick based on the parts that affect your install - not the brand story.

Choose Heatable if…

You like the clarity of an “all-in” bundle (e.g., Heatable One) and the inclusions match what you want.

Choose BOXT if…

Their like-for-like quote is cheaper for your exact boiler + install scope (same model, same controls, same complexity).

You specifically want the plan/finance structure they offer (including BOXT Life, or particular finance terms available for your boiler).

Their availability is better in your postcode and they’ve confirmed your install assumptions properly (photos, scope checks, etc.).

The fairest way to decide (takes 10 minutes):

1. Get a quote from both for the same details

2. Match boiler model + warranty length

3. Match “included” items (filter, controls, flue work, cleanse/flush)

4. Compare earliest install date

5. Pick the provider that’s clearest on scope and quickest to support you if something needs tweaking
