Which? Local Review
Customer Service
I had a low pressure fault on my combi boiler: no heat, no hot water! But 1st Gas came round within three hours and cleared the fault professionally, courteously and efficiently --- and at a fair price. Well impressed. I would certainly recommend this firm.

I have just used this firm for the first time and I am very impressed with the quality of service I have received. They arrived on time completed the job quickly, efficiently and very tidly and were very good value for money. The engineer, Jeff, was polite patient - he answered all my questions and tidied up. I will be using them again to install a full central heating system. I can heartily recommend them.
New Boiler Installation
Customer Service
After 20 years it was time to replace the old creaking boiler so I called up 1st Gas who came out to assess the boiler that was in situ and advise on the type of boiler to replace it. A day, time and a price was agreed and the work was carried out to a high standard and much quicker than I expected. I was also particularly impressed with the tidiness and cleanliness of the work, leaving the work area spotless and I now have fully functioning boiler which should save me money on my gas bills. Highly recommenced.

Very professional
Customer Service
Our old Vaillant Combi was replaced by a Worcester 30si Combi Boiler. The work was efficiently & tidily carried out, the installers were very pleasant & helpful. The experience was far better than the ones we have had with a national company.

I contacted 1st Gas Engineers after having been led down by another company. Having checked Which Local I contacted several companies for a quote to install a new boiler. 1st Gas Engineers quote was very competitive and we arranged a date for the installation. They turned up on time, did a fantastic job (going out of their way to hide the pipes, which the other companies had not mentioned) and left the place spotless at the end of the job. I have no hesitation in recommending this company.
