How Do iHeat and British Gas Compare?
Choosing a boiler installer? It’s more than just picking a name. As a heating specialist of 15 years, I’ve worked with both iHeat and British Gas. Each has its own style, strengths, and weaknesses. In this in-depth guide, I’ll share my honest, real-world take – packed with insights, quirky experiences, and plain talking about what you get with each service. By the end, you’ll have a proper sense of who’s best for your home.

Boiler Options Available
Nobody wants to be cornered into one brand. The more boiler choice, the better. iHeat offers a wide selection: Worcester Bosch, Vaillant, Ideal, Viessmann, BAXI. All the crowd-pleasers and a few underdogs. I’ve specced out systems for quirky flats and rambling old farmhouses – and found iHeat could sort both.
British Gas mainly pushes its own rebranded boilers (often made by Worcester Bosch) and a handful of Safe Bets (like Ideal and Vaillant). Solid performers. But I’ve seen British Gas plans fall short if you want a particular model or eco boiler bells-and-whistles.
Want choices? iHeat wins hands down in variety. Plus, the ability to mix and match heating controls in their quote builder is honestly a treat.
Ordering Process & Online Quotations
Ordering a boiler shouldn’t feel like a Root Canal. iHeat made it easy for my mum (not a tech whizz) to get a quote on her iPad – four questions, a postcode, a few clicks, and done. They ask about your old boiler, house size, and hot water usage, recommending suitable models. No sales spiel, just practical suggestions. Their online system gave an instant, detailed summary including fixed price, installation date options, and finance—all in under 2 minutes. Try for yourself at iHeat.
British Gas? It can take days just to book a survey.
Usually, they ring you up and insist on an in-person visit, even for simple swaps. The website is slick but directs you to another human—fine if you like chats, clunky if you’re after speed or privacy.
For convenience seekers, iHeat nails it every time.
Pricing & Finance: Cost Clarity vs “Extras”
Let’s face it, nobody likes hidden costs. When comparing quotes for my own rental project, iHeat’s price came up hundreds less than British Gas for a comparable Worcester Bosch combi, complete with flush and filters. And not once did they tack on “recommended” extras or upsell me.
Their finance options are pretty flexible—a quick check doesn’t impact your credit file. You can spread the cost over 12 months interest-free, or go longer if you wish. Every figure was clear up front at iHeat.
British Gas traditionally charges more—sometimes a lot more. Their list price rarely covers things like pipe upgrades, thermostats, or even disposal; these get added on survey day. I’ve seen bills balloon after the surveyor spots an “unusual flue,” especially in older homes.
Transparent pricing? iHeat went the distance for me.
Installation Day Experience
Installation is bread and butter for both. Here’s the difference I found. When my aunt had her new system fitted by iHeat, the team arrived on time, wore shoe covers, and walked her through the new controls. The job was tidy. All waste—boiler crate, old pipes, packaging—vanished when they left. Installers were Gas Safe registered and showed their ID, unprompted. Genius.
British Gas fitters also deliver professional work. They’re thorough, know their trade, and tidy up decently. Yet, I’ve seen appointment windows missed and jobs split over two days, causing disruption. The comfort of a big brand, perhaps, but the experience can feel less personal.
For speed and care, iHeat set themselves apart on installation day.
Aftercare & Customer Support
Once your hot water’s steamy and radiators pop, what if something goes wrong? iHeat keeps it straightforward: warranty registration sorted post-install, clear aftercare paperwork, plus dedicated helplines for any niggles. When I tested their response, I had a real human on within 50 seconds—amazing. Check it yourself at iHeat.
British Gas offers long warranties (up to 5 or 10 years—and HomeCare plans are available). Their phone support is 24/7, and they have a massive network of engineers. But in my experience, response times can be slow for non-emergencies. Repairs often get shuffled behind customers on maintenance contracts. If you want quick answers, iHeat makes a better impression.
Written communication? iHeat emailed regular updates and reminders post-job, which was a nice touch.
Hidden Extras or Unexpected Challenges?
Even the smoothest jobs can hit snags. I value honesty. iHeat warns if a job looks “non-standard” (quirky pipework, tricky flue locations) and will request a few extra photos before confirming. No surprises for you or their engineers.
British Gas often adds “scope of works” items after surveys—think relocated gas meters or “essential” power flushes at extra cost. Customers might be at their mercy once the job starts.
I had one customer quoted for a £1,500 flue upgrade that two independent engineers said wasn’t needed. For straightforward, upfront honesty, iHeat impressed me.
Trust, Reputation, & Online Reviews
Social proof speaks volumes. iHeat proudly displays a 4.9/5* score on Trustpilot from more than 11,000 reviews. Course, not everyone will be happy—we all know boilers can be fussy, especially in a British winter. But the feedback is overwhelmingly positive: quick, painless installations and clear communication. Read stories for yourself at iHeat.
British Gas is a household name—familiar, established, maybe more of a “safe pair of hands” for some. However, their Trustpilot rating currently sits below 4*, and I regularly hear grumbles about price hikes and slow call-backs from my customers. Not a deal-breaker, but something to bear in mind.
If reputation is your compass, iHeat points true north.
Speed & Availability: Need It Tomorrow?
In emergencies—or when it’s freezing—speed matters. iHeat routinely had next-day installation slots, even in December. Numerous times, I tested their availability by requesting “emergency” installs and was offered options within 24–36 hours. I recommend checking slot availability yourself at iHeat.
British Gas can be prompt, especially for contract customers, but public appointments can mean a wait during busy spells. I’ve sat in chilly kitchens waiting two weeks for British Gas engineers to appear, and let’s just say—frustrating.
Need a boiler quickly? iHeat came up trumps for me.
Who Should Choose iHeat? Who Might Prefer British Gas?
If you like fast quotes, predictable prices, and a huge boiler selection? iHeat is a superb choice wherever you live. Great if you value:
- Hands-off online process
- No-nonsense, transparent quotes at iHeat
- Quick turnarounds & quality installers
- Prompt, human support
Maybe you feel safer with a brand everyone knows? British Gas might suit if you already have (or want) a bundled HomeCare plan, or you favour in-person surveys and don’t mind paying a bit extra for brand heritage.
Neither service is perfect. Boilers are fickle things, and people’s needs aren’t one-size-fits-all. But value-for-money and sheer ease? iHeat is my go-to recommendation.

Which is cheaper, iHeat or British Gas for new boiler installations?
You might assume big brands hand out bargains, but that’s not always so. iHeat often undercuts British Gas—with price tags frequently hundreds lower for the same Worcester Bosch or Vaillant model. British Gas sometimes charges more simply because of their household name. No hidden fees tucked away in fine print with iHeat, either. Curious? Check sample quotes at /1—see for yourself.
Do iHeat and British Gas offer similar boiler brands and models?
Both companies play in the top league—Worcester Bosch, Glow-worm, Vaillant, Viessmann, the works. Yet, iHeat sometimes bags exclusive access to newer, high-efficiency models before British Gas updates its catalogue. British Gas might bundle more extras, but iHeat focuses on the latest gear at lower prices. Feeling left in the dark? Hop over to /1 and compare what’s on offer, side-by-side.
How do installation times compare between iHeat and British Gas?
Speed matters—no one wants a cold house. iHeat generally gets installations done quicker, sometimes next-day if you hit the sweet spot with timing. British Gas can take days or even weeks, depending on their schedule. It’s what separates nimble from massive. Want your boiler in before your toes freeze off? See same-week availability at /1.
Who offers better customer service—iHeat or British Gas?
Truth be told, British Gas has more call handlers, but iHeat wins on personal touch. Their reviews brim with tales of bend-over-backwards service and quick fixes. British Gas isn’t bad—just less nimble. For people tired of long hold music and robot voices, iHeat’s team is refreshingly human. Don’t take my word—peek at real stories linked from /1.
Are the warranties from iHeat and British Gas equally comprehensive?
Both offer whopping boiler warranties—up to 10-12 years is pretty standard now. The catch? British Gas often wraps their long warranties around their own servicing packages. iHeat provides long warranties minus the fuss, and usually without tying you into expensive service plans. Want to see the fine print in plain English? Visit /1 for a clearer breakdown.
Is financing available through iHeat and British Gas?
Upfront can sting! Both firms break the bill into friendly, monthly instalments if you’d rather. APR rates differ—iHeat’s finance options have been known to undercut the bigger outfit. Application is zippier and more transparent with iHeat. Give your spreadsheet a rest and check easy finance details at /1 to see the difference in real figures.
Do iHeat and British Gas both use Gas Safe registered engineers?
Safety’s not negotiable. Every engineer on both teams is Gas Safe registered—non-starters otherwise. iHeat’s engineers usually include a direct local installer who lives just down the road. British Gas leans on their own big crew. Either way, you’re covered. Fancy putting a face to a name before the door knocks? Explore engineer profiles at /1.
Why do customers rate iHeat highly compared to British Gas?
Honest reviews spill the beans: iHeat runs a tight ship—fast responses, no jargon, and actual people treating you like a person. The word “refreshing” pops up a lot, with one grandmother writing, “They actually explained what was happening in my kitchen.” British Gas? Reliable, yes, but a bit more like waiting at the post office. Don’t just listen—read direct feedback at /1 before you decide.
