Expert Boiler Installation, Designed to Last

Your boiler is the heart of your home — and replacing it isn’t just a quick job, it’s an investment.

At Green Gas & Energy, we design and install high-performance heating systems across Newcastle, Jarrow and the wider North East. Whether you’re upgrading to a combi, replacing an old heat-only boiler, or converting your entire setup — we combine expert advice, tidy workmanship, and top-tier technology to deliver comfort, efficiency, and peace of mind.

✅ It’s not just about the boiler
We design the system around it — flow rates, controls, radiators, hot water needs — so it runs efficiently, lasts longer, and performs properly from day one.

✅ Trusted, qualified professionals
We’re Gas Safe registered, Intergas-accredited, and low temperature heating specialists. No guesswork. No corner cutting.

✅ Honest, expert advice
We’ll help you choose the right boiler and setup — without pressure, upselling or jargon.

✅ Local and proud
We’re based in Jarrow and serve homes across Newcastle, South Tyneside and beyond. Trusted by hundreds of homeowners in your area.

✅ We’re not for everyone
If you’re after the cheapest quote, we might not be your best fit. But if you care about getting it done properly – with expert design, tidy workmanship, and long-term performance – then we might just be exactly who you’re looking for.

Why Choose us?

Your Boiler Installation, Designed to Perform

A new boiler isn’t just a replacement — it’s a chance to improve your entire heating system.
Done properly, it should heat your home faster, use less gas, and stay reliable for years to come.

At Green Gas & Energy, we engineer efficiency into every install — and that efficiency pays you back every time you turn the heating on.

We consider:

✅ Correct boiler sizing and flow rate calculations

✅ Your usage patterns, room layout, and zoning potential

✅ Pipework compatibility and futureproofing

✅ Smart controls for lower running costs

✅ Full water treatment and protection, as standard

System flushing included — always.
We won’t install a new boiler without flushing and treating your system. Every install includes at least a
Magnacleanse flush, chemical treatment, and inhibitor — no “optional extras”, no corners cut.

Done properly, not rushed.
Our installations typically take
two days, because we don’t just swap the box — we take the time to design, protect, and test the whole system. Most companies rush through installs in 6–8 hours. We think your home deserves better.

How We Compare to a Typical Installer

We believe how it’s installed matters just as much as what’s installed. Here’s how we stack up

  • Every system includes a Magnacleanse flush and full water treatment — as standard

  • Installations typically take two full days — because we don’t rush it

  • Systems are designed for your home, not just swapped like-for-like

  • We integrate smart controls and show you how to use them

  • Your system is installed by our own certified, accredited experts

  • We offer up to 12-year warranties when serviced annually

  • Our aftercare is local, personal and responsive

  • Our quotes are transparent — no last-minute surprises

What You Might Get Elsewhere

  • System flushing often charged as an expensive add-on

  • Installations rushed in 6–8 hours, with corners cut

  • Like-for-like replacements without thought to efficiency

  • Controls left at factory settings — or not explained at all

  • Subcontracted fitters with mixed experience

  • Standard warranties of 2–5 years

  • Hard-to-reach call centres for aftercare

  • Prices that look low — until the extras are added

There’s a difference between boiler fitting and heating system design.
We do the latter — every time.
