Heatable vs British Gas: Which Boiler Installer Is Right For You?

Heatable is online-first, fast quotes, and a process built for speed and convenience.

British Gas* - the utility giant, with a large engineer network and a more quote journey options (think calls, home visits, and bundled cover options).

Neither is automatically better - it comes down to what matters most to you - price, how quickly you want it done, how much guidance you want, and what you expect after install day.

We’ve kept this guide balanced and fair, so you can make the right call for your home (and your patience level).

🔑 Key points - Heatable vs British Gas:

• Heatable is online-first and speed-focused - British Gas can be more guided (calls, home visits, cover options)

• Quote journey - Heatable aims to give a fixed price fast online - British Gas often confirms via a call back and can offer home visits

• Speed - Heatable can be next-day in many areas - British Gas typically says 1–3 days depending on job complexity

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

• Warranty - Heatable warranties vary by boiler/model - British Gas promotes a 5-year warranty with annual servicing required

• Aftercare - Heatable is more “install + clear support routes” - British Gas strongly pushes HomeCare-style cover (waiting period, excess options)

• Trust signals - both are Which? Trusted Traders - still check the quote docs, inclusions, and how snags are handled

Heatable vs British Gas Comparison Table:

[1] The quote process - online-first vs “confirm with an expert”

Heatable:

Heatable’s quote journey is designed to be fast and fully online.

You answer a few questions, upload photos, and get a clear price - with fixed pricing positioned front and centre.

In many areas, next-day installs are available when booked before 3pm.

Best for - people who want to get to a price quickly, without multiple appointments or back-and-forth.

British Gas:

British Gas typically starts online too, but leans more on expert confirmation before you’re fully locked in.

It’s explicit about arranging a call to double-check the details behind your fixed-price quote - and it also offers an in-person home visit route for a “personalised, fixed-price quote.”

Best for - people who want more reassurance up front, especially if the property is unusual or the job might be more complex.

Reality check (applies to both):

A “fixed price” is only as accurate as the info collected at the quoting stage.

If your install is more complex - for example, boiler relocation, a tricky flue, upgrades to pipework, awkward access, or condensate routing changes - confirming the details early matters.

That’s not a Heatable vs British Gas thing; it’s just how boiler installs work.

[2] Price - who’s cheaper?

There isn’t a permanent winner here.

Boiler install pricing moves around - and the “cheaper” option can change depending on your home and what’s included.

What actually drives the price:

• Your postcode (labour rates and availability vary by area)

• Boiler model (and the right output for your home)

• Install complexity (simple swap vs relocation)

• Flue and condensate routing

• Controls and system upgrades

• Any required remedial work (e.g., pipework issues, gas upgrades, unexpected faults)

How to compare fairly (so it’s apples to apples):

• Quote the same boiler model (or the closest equivalent)

• Match the warranty length you’re actually being offered

• Match what’s included: controls/thermostat, filter, flue kit, flush/cleanse, any upgrades

• Check what’s assumed versus what’s guaranteed in the quote paperwork (this is where “cheap” quotes can quietly change later)

[3] Speed & availability

Heatable:

Heatable leans hard into speed.

British Gas:

British Gas is generally more cautious with timelines.

It says installs are “usually” 1–3 days, and flags what most engineers will tell you anyway: a like-for-like swap is typically quicker than changing boiler type or relocating it.

What this means in practice:

If you need heating and hot water urgently, Heatable may be stronger on speed - but British Gas can still be quick depending on your area and the type of job.

The most reliable way to judge it is simple: compare the earliest available install date for your postcode (for the same boiler and the same scope of work).

[4] Warranties - what matters (and what people miss)

Heatable:

Warranties with Heatable are typically manufacturer-backed, and the length depends on the boiler brand/model you choose.

Separately, Heatable’s also offers a 12 months of workmanship protection after installation.

British Gas:

British Gas promotes a 5-year warranty including parts and labour with its boiler installs, and it’s clear that you’ll need an annual service to keep that warranty valid.

It also points customers towards HomeCare options, which it says can include an annual boiler service (helpful if you’re the type to forget to book it).

The key checks (either way):

• What’s the exact warranty length on the specific boiler model quoted? (Don’t rely on “up to X years” headlines.)

• Who provides the cover: manufacturer warranty, installer warranty, or a mix?

• What are the conditions: annual servicing, registration deadlines, approved controls, installer accreditation, etc.? (For example, Viessmann lists models where cover can be extended up to 12 years, but it’s conditional.)

[5] Aftercare - “installer support” vs “cover plan” thinking

This is where the difference feels most real - because it’s less about the install and more about what you want after the install.

Heatable:

Heatable’s aftercare angle is closer to: get the install done properly, back it up, and keep support straightforward.

Practically, Heatable also highlights a defined 12-month workmanship protection period post-install.

British Gas:

British Gas makes the “ongoing protection product” route very obvious with HomeCare.

On its own boiler/heating cover page it calls out:

• Annual boiler service included

• Unlimited callouts

• Parts and labour included (you pay an excess per completed repair)

• No claims in the first 14 days

• Excess options commonly shown as £0 / £60 / £99 (with £60 often used in examples)

Plain English:

If you like the idea of a subscription-style safety net after install day (service + callouts + predictable “excess per fix”), British Gas makes that path easy to choose.

If you mainly want a clean install + manufacturer warranty + a clear workmanship period, Heatable’s model will usually feel simpler and less “insurance-y.”

[6] Trust & reassurance (aka: “Who do I actually trust with my heating?”)

Both brands lean on Which? Trusted Traders in their boiler-install messaging - and that’s a decent starting filter, not a finishing decision.

Heatable is endorsed as a Which? Trusted Trader for boiler installation service.

British Gas also markets its installs as carried out by its Which? Trusted Traders, and has an endorsed profile on the Which? directory too.

What really impacts your life is:

• Clarity of scope (what’s included vs what’s “if needed”)

• Paperwork + commissioning (benchmarks, settings, handover, warranty registration)

• How snags are handled if something needs tweaking after install (speed, clarity, no faff)

If you’re stuck between them, don’t overthink the logo - compare the quote documents and the aftercare route like you’re buying peace of mind, not just a boiler.

Who should pick Heatable?

Heatable tends to suit you if you want:

• An online-first journey and a fast route to a clear price (less back-and-forth)

• Next-day installation in your area (where offered)

• A simple, clean aftercare setup, plus 12 months workmanship warranty

Who should pick British Gas?

British Gas tends to suit you if you want:

• A brand that offers both online and in-person quote routes

• A quote confirmation call built into the process (handy if your home/job is more complicated)

• The option to bundle longer-term peace of mind via HomeCare (service + repairs structure)

The fairest way to decide in 10 minutes:

Get both quotes - then compare like-for-like:

• Same boiler model / output

• Same warranty length (and the conditions that keep it valid)

• Same inclusions (controls/thermostat, filter, flue kit, flush/cleanse, TRVs if included)

• Earliest install date for your postcode

• Aftercare route - who do you call first, and what’s actually covered (vs “we’ll review it if needed”)

If you do that, the “best” choice normally becomes obvious - because you’re comparing real scope, not just headline promises.
