Worcester Bosch
Often chosen for warranty confidence and broad familiarity. When matched to the property and commissioned properly, they’re solid.
Best for: homeowners who want “mainstream dependable” and easy servicing availability.
Worcester vs Vaillant vs Ideal
what we actually see in London homes
People ask this on the phone more than you’d think. Not “what’s the best boiler?” — more like: “My mate says Worcester. The other guy swears by Vaillant. The internet says Ideal is good now… who’s lying?”
We install all three. We’re Gas Safe engineers based in East London (E7), and we’re in and out of properties around Forest Gate / Stratford / North & East most weeks. If you want help choosing based on your actual home (not a forum argument), call +44 7727 154 746.
Engineer-led advice
Worcester • Vaillant • Ideal
Installed right = matters most
The honest answer (before we get nerdy)
All three brands can be a great choice. The bigger deciding factor is whether the boiler is sized properly, the system is clean, the flue and gas side are correct, and the commissioning is done like someone cares. If you want the proper install standard we work to, start here: book your boiler installation properly.
Vaillant
Quiet, refined, and tends to suit people who care about controls, efficiency, and a “nice” feel to the system. Good kit when installed right.
Best for: people who want smooth operation and don’t want the boiler to sound like it’s working out.Ideal
The “surprise contender”. Ideal has improved massively over the years, and for some installs it’s a very sensible value choice.
Best for: budget-aware installs where you still want a proper job and a decent warranty.Brand affects cost, but install realities affect cost more. If you’re comparing quotes, this helps: why boiler prices jump around.
A little moment that happens all the time
We’ll be in a kitchen in Forest Gate, cupboard doors off, old boiler hanging there looking offended… and someone says: “Just put in whatever you’d put in your mum’s house.”
That’s actually a good way to think about it. Because the “best” boiler depends on the home and the people in it. One bathroom flat with good mains pressure? Easy. Busy house with two bathrooms, back-to-back showers, and a half-tired heating circuit? Different conversation.
If you want to talk numbers, our cost pages help, but we’d rather not guess. You can check see real installed costs here, then call us for a range based on your setup.
How we pick the right brand for a property (without the sales talk)
When we’re advising a homeowner, we don’t start with brand. We start with the house: hot water demand, water pressure, pipework condition, space, flue route, and how you actually live. Then brand becomes the finishing touch.
Noise and “feel”
In flats, especially where the boiler’s near the living space, noise matters. Some people are unbothered. Some people hear everything.
Tell us where the boiler sits (kitchen cupboard vs hallway) and we’ll factor it in.Parts and support
If a boiler ever needs a part, you want it quickly — not a three-week wait while you boil kettles for baths.
We lean practical. What’s serviceable locally wins.Controls + efficiency
A good boiler with bad controls can still waste money. Proper setup and reasonable flow temps make a difference you feel.

If you want to avoid the “quote changed on the day” thing, here’s the checklist we use: get an accurate quote without chasing.
What people care about after the install
Funny thing: nobody rings us a week later to say “wow, the badge is lovely.” They call out the basics: tidy work, no drama, and the boiler behaving.
“My boiler went wrong… Abdul and his team came and fitted a new one. They worked without taking a break, cleaned up when they were done.”
Alison Louis“Great service prompt and efficient. Fitted a new boiler at a very competitive price also took away old boiler and all other waste.”
Grant Hodges (Local Guide)“Always punctual, professional, and true to their quote — highly recommended!”
Elimelech HalberstamWorcester vs Vaillant vs Ideal: FAQs
Which brand do you fit the most?
It varies by property and budget. Worcester and Vaillant are popular choices, and Ideal has become a very sensible option on many installs. We’ll recommend what suits the house — not what’s trendy this month.
Is the “best boiler” just the one with the longest warranty?
Warranty helps, but it’s not the whole story. A long warranty still relies on a correct install, correct commissioning, and the system being protected. If corners are cut, the warranty won’t feel very comforting later.
Does brand choice change the installed cost a lot?
The boiler price changes, yes — but installation complexity often changes the total more. If you’re comparing quotes, start with: why boiler prices jump around.
Can you advise if I’ve already picked a boiler?
Yes. Call +44 7727 154 746 with the model name and your setup (bathrooms + cylinder/no cylinder), and we’ll sanity-check it. If you’d rather message, send photos via the contact form and include the model you’re looking at.
What matters more than the brand?
Sizing, flue safety, gas supply, system cleanliness, protection (filter/inhibitor), and proper commissioning. That’s the stuff that decides whether you enjoy the boiler or keep chasing faults.
