We have used Alsto-heat Ltd on three separate occasions now and we have been very pleased with their service each time. Two occasions were to install and plumb up new sinks and the latest occasion was to repair a leak we had from our boiler. We currently have a HomeCare agreement with British Gas for our boiler, but we had a similar problem last year and British Gas came to repair, but now it's happened again so we decided to call on Alsto-heat. This was just before Christmas and we had no heating. Despite being very busy, Steve arranged for someone to assess the problem the same day I called and

Rang Alsto-Heat, Seemed Friendly and had lots of good reviews. My boiler was losing pressure and seemed to be leaking. The hot water and Heating was still working even with these problems. Alsto-Heat said the boiler was beyond repair and quoted for a new boiler. I did not believe them and got worcester bosch to look at it. It just needed a small part. Quote seemed very high for the price of the boiler they wanted to install. This is why I got a 2nd company in. Glad I did boiler is working great now.

I have used these plumbers to supply and install a Worcester Bosch boiler, rads and the full heating systems for my in-laws 3 bed house in the Cheltenham area which cost approximately £4.5k which was in the average territory for what needed to be done.
Few months later I needed the same for our new house which needed a bigger boiler and 13 rads with 2 towel rads. At first everything went okay until Roger with a South African accent wanted to cut corners. Naturally I wasn’t having none of it as I was paying approx £5k for this. I later realised that Roger just wanted to get the job over and

Alsto-Heat fitted an emergency boiler for me and I received top customer service from them. The workmanship was excellent and I would highly recommend them as a company.

I've used Alsto Heat many times over 30 years or so, and in the past found them a good local company whose charges compared well. Not so any more though. I'm slowly paying off a bill for almost £500, when the original request was simply a gas safety check plus re-siting of an old heater (gas connection already there for this).

My gas heater had been left in pieces, needing a new thermo-couple, and I waited several weeks to hear from them. Eventually chasing this up, I was told that the part could not be obtained. In the meantime, I had been sent an invoice for well over £400 (and
