I couldn’t be happier with the service…

I couldn’t be happier with the service I received from Next Level Boilers! From the initial survey to the final installation, everything was handled with professionalism, expertise, and care. The team arrived on time, explained the entire process clearly, and worked tirelessly to get my new boiler up and running.
What really stood out was their attention to detail and respect for my home—they left everything spotless. The new system works perfectly, and I’ve already noticed a difference in heating and efficiency. They also took the time to walk me through how to use the new controls and answered all my questions patiently.
If you’re looking for a reliable, knowledgeable, and friendly boiler installation company, I highly recommend Next Level Boilers. Truly top-notch service from start to finish!

Tenant happy with gas engineer

I'm a tenant and my landlord uses Lenny to service my boiler and fix it when there's any problems. Lenny is a nice bloke and I'm always happy to have him do what needs doing.

Good Company All Round

I was recommended this company from and neighbour who had a new boiler fitted by them and I’m happy with the job they did for me. They installed a new boiler for me also and did a good job. I would recommend them also.

Dont go anywhere else but here for your boiler

I would thoroughly recommend Len for any servicing, repairs or installation. His approach to customers is second to none, you feel completely confident in his ability to problem solve and are reassured by the quality of his workmanship. He is always going to be our go to Boiler Man.

Everyone I spoke to was super friendly, helpful and knowledgeable.They were able to squeeze us in at very short notice for a new boiler installation,which helped us out because our boiler had stopped working completely . Got it all done in one day and cleaned up thoroughly after themselves. Highly recommended.
