Had a broken boiler

Had a broken boiler - big surprise and shock but the guys at h3g heating did an amazing job getting a state of the art new boiler up and running in under 24 hours at a very fair price. The guys were super knowledgeable, chilled and kind. Would 100% recommend and use again!

Great company!

I had Amir visit following a CO alarm and my gas being turned off by the gas board. Amir ran a complete CO test and spoke me through what he was doing. I was also able to ask lots of questions and Amir even went out of his way to speak to my neighbour about their CO alarms. Amir also came with 24 hours and was really easy to work with. I would use this company again.

Install a new Vaillent boiler

This company is at top class. We are so glad to find H3GS after previous company messed us up. We contacted H3GS on Tuesday night, by Wed Amir is in our house and give us all the necessary information and advise re a new boiler. By Friday our new boiler is installed. Amir even comes out on Sat to do the after installation adjustments. Amir and his colleague are very professional, super polite and mostly very efficient, in fact, I only see such efficiency in Far East. From now on H3GS will be the company we first to call if we need any heating/plumber service.

I couldn't fault Amir and his team.

I couldn't fault Amir and his team.
When our boiler broke, they were here in under two hours and then next day installed a new boiler at a very competitive price. The communication was second to none, and they made sure everything was clean and tidy afterwards.
100% recommend. Don't go anywhere else

Boiler replacement project

Amir and Hamed were very helpful, professional and polite. Everything was clearly explained and clearly stated;
We were also very happy by how fast they responded and scheduled the work. The quote was sent promptly and was very clear, detailed, and gave us various options.

Great service!

Amir is great, he has done quite a few jobs for us over the years. Given a problem, he can figure out what solution is needed and recently fixed our showers so they now are like hotel quality. Very happy with the finished product.

We used H3GS to do a gas

We used H3GS to do a gas, electric and central heating survey on a property we are purchasing. They were responsive, efficient and provided a clear report within 24 hours, exactly what we were looking for!

Fantastic service as always from Amir and the team.
He made time to come and diagnose the issue at late notice and gave me the options on a replacement boiler and then managed to get the parts a day earlier than expected.
I have no hesitation in recommending H3gs Heating

Would recommend

Really great service from Amir and his team.

I had comprehensive heating issues that needed dealing with in my flat, Amir was very helpful over the phone to discuss what could be wrong, came out and assessed and was able to perform all work the same day.

Would recommend!

Highly recommend - quick attendance, excellent service

Highly recommend. I contacted H3GS late on a Monday evening about an underfloor heating breakdown, and Amir came out on Tuesday morning. The callout fee was very reasonable especially given the turnaround time. He identified the root cause and got the heating working again and identified several issues that were directly caused by the original issue that he recommended get sorted for prolonged life of the system. Booked in on Friday and all done within half a day. Cannot fault the service and excellent value for money. Would definitely use H3GS again.
