Got a new boiler installed after old one was coming to the end of it's life.
I'm impressed with how quickly he came out and seen us multiple times at short notice during the recent heavy snow. Always responded to digital communications very quickly. Very efficient and straight to the point worker.
Does a good job at explaining the technical issues in terms those unfamiliar with gas and heating etc may not be experienced with.
Very fair transparent pricing and obviously take pride in their work.
Very professional, tidy process and respect for the property.
Very lucky to have such a good service in my local area. The whole process couldn't have went any smoother.
What was previously a stressful situation of having an old broken boiler, a baby and small children in snowy, icy weather was quickly resolved and we're very grateful for the turnaround time during this busy time of year for heating and gas engineers.
Best of all, Chris is a genuinely friendly, empathetic guy and skilled at what he does.
Will 100% use again if needed and will be my first recommendation to all friends and family.

Old boiler broke and despite having home emegency cover through my house insurance couldn't be reliably fixed leaving us very cold over several days. we contacted Premier Gas re a new boiler, they came and gave me a competative quote the same day and fitted the boiler the day after. They turned up dead on time and completed all the work within hours. We are very happy and grateful.
Premier Gas is a good professional company. They have done three bathrooms in our home to a very high standard. I would highly recommend them and wouldn’t use anyone else.
Chris and Harry are always professional, friendly and helpful, they have fitted my central heating system in my renovation property and I would highly recommend them for any gas and heating work.
Chris was professional from the very first contact. He was so accommodating and really helpful with all explanation of work and cost. The installation was smooth and both Chris and Harry continued with their professionalism; friendly, courteous, and even had time to answer the questions of our three year old. Complete peace of mind with our new boiler. Could not be happier. Thank you so much.
No hesitation in leaving Chris and his team a 5 star review, I would leave a 6 star review if I could. From start to finish everything was handled professionally and efficiently. Great standard of work installing my new boiler yesterday. Chris arrived exactly when he said he would and left the house clean and tidy once finished. Absolutely brilliant work all round.
Super helpful and excellent job on the plumbing on my new toilet in an extension.
Attended quickly to give quote. Listened to the requirements and performed the plumbing activities satisfactorily including a couple of visits for first and second fixes. A good job at a fair rate. Recommended.
Chris recently fitted my bathroom and I couldn't be happier with the results.
From the initial consultation to the completion of the project, Chris was brilliant, he arrived on time, was well-prepared, and communicated clearly throughout the entire process.
Not only is Chris highly skilled in his trade, but he is also friendly, and approachable.
It was refreshing for a trades person to be so reliable throughout my house renovation.
I highly recommend Chris and his team.
