I can't recommend Alsto-Heat highly enough. We needed a Worcester Bosch boiler replaced in a hurry when our current boiler failed. The quote was competitive, fitters arrived on time and started work immediately, the old boiler was out within an hour and work was completed by mid afternoon, We were very impressed with the Fitters, their communication whilst doing the job, the standard of their work, and the way they cleaned up when the job was completed. I have no hesitation in recommending Alsto-Heat.

Alsto Heating is one of those rare Family owned businesses with friendly helpful, courteous staff whos work is to the highest standards. Proper high integrity old fashioned trades folk who just want to do a first class job. My job was not simple. The whole of the old system and some of the radiators needed replacing with a
modern combi-boiler set-up. The quality of the workmanship was excellent, from perfectly straight well hidden pipe work, neat soldering, clean and tidy, sound ongoing advice, to boiler tech installation know how. Very good value for money and and a safe pair of hands.

Pete was fantastic with explaining the process and guiding us through what is our best option. Was available to take our call and was always professional with his responses. The work was booked in quickly and as promised completed in the time limit quoted. Will certainly be using them again and be recommending to friends and family. Additionally Amy was fab with coming back to me on emails and missed calls!

I was extremely happy with the job from start to finish. The team were excellent and extremely helpful answering any questions we had about the system. The installation was completed within a day, which was very much appreciated. Alsto-Heat were able to source the specific boiler I wanted and the price for the work was very reasonable. I wouldn't hesitate to recommend them to anyone.

Friendly, tidy and thorough , sent by Worcester Bosch , best price by far and I compared. New boiler installed and they sorted out the pipe work that was previously bodged by Stroud district council contractors so I have really hot water straight away for the first time in 12 years, loving it, better pressure and really hot radiators too, they did the most thorough job ever done here , plus stayed here longer after a long day to set up the slick new controls properly . Thank you!

Alsto-Heat Ltd has just fitted a new bathroom for me and it was a first class job. As a Landlord for the past 15-2- years Alsto-Heat have been attending to many of my properties including my own house to carry out all works from plumbing repairs, gas checks to new boiler installations and I would highly recommend them for any central heating and plumbing works needed.

Can't speak highly enough of Alsto-Heat, who replaced a boiler at my elderly Father-in-Laws house. Work was carried out within days of accepting competitive quote, and was so impressed with the Fitters, their standard of work, and their neat and tidiness. When I visited, again I was so impressed with the standard of workmanship (and i'm hard to please!!). It has been a pleasure to deal with this Company, from the first call to Amy, to meeting Pete (Lloyd) on site to discuss work, and I have no hesitation in absolutely recommending Alsto-Heat for all heating/plumbing needs

We have now reinstalled my husband's mother back into her home. She was delighted with the new boiler and radiators and I am sure she will be even more pleased with them when the weather gets cold again. Thank you for getting the work done so efficiently.

We wanted you to know that we are very pleased with the shower your engineers fitted last Thursday.

The installation went without a hitch and the workmanship is first class. We're particularly pleased with the way the job was finished, especially the new tiles that were needed to cover alterations made to the pipes. Your men worked diligently all day and were patient and friendly to us when we asked questions.

Performance exceeds all expectations and it's now a pleasure to shower in the morning.

Well done and thank you.

Hi Pete and Team I am very grateful for the support you have been recently. You were the only firm out of a fair number who actually had the decency to keep me updated at each stage. I will be referring Alsto to anyone requesting plumbing contacts.

Over the course of the two days it took to complete the work I noted the way all three of the staff involved kept their heads down, got on with the job and left the room clean and tidy at the end of each day

I would not hesitate to recommend the company or its staff in the future.
