 Trustindex verifies that the original source of the review is Google. Really great service! AllGas sorted out a new combi boiler for us and the installation was prompt, neat and efficient. Easy to contact and very friendly and professional throughout.  Celia was fantastic via e-mail at sorting everything, Stephen was helpful and explained what needed to be done really clearly, and Eddie and Lee both worked efficiently and left the house spotless when the works were completed. I'd definitely recommend them!

 Trustindex verifies that the original source of the review is Google. I used Allgas earlier this year to replace my gas boiler, and could not recommend them highly enough. They were extremely professional, and even though they were very busy they moved some jobs around in order to fit me in sooner. They arrived when they said they would and did a very neat job, I could not have asked for more.

 Trustindex verifies that the original source of the review is Google. Allgas were so professional. I was let down by 2 plumbers, no replies, no quote after calling to see job. I tried Allgas they were professional and extremely prompt.
They arrived within days completed job and were clean and tidy.
Job was fixed and no issues since.
Highly recommend

 Trustindex verifies that the original source of the review is Google. I would highly recommend Allgas. Celia in the office was very quick to respond to my emails and made the booking process simple and stress-free. Paul arrived exactly on time, was lovely to deal with, and completed the work quickly and efficiently. He also left everything clean and tidy afterwards.

Overall, a very professional and reliable service, and I would happily use them again.

 Trustindex verifies that the original source of the review is Google. Allgas have been excellent, I have been using them since 2022 and they are professional, prompt to get back with queries, on time, and really know their job. We just had our gas boiler replace and the piping changed and upgraded, the work was perfect and the lads were very clean also. Recommend this company.
