Customer Feedback

``The service I received from AHS was fantastic. I was recommended to them by my dad who has used the company for a number of years. The technicians that came were not only highly skilled but also willing and wanted to explain each part of the process to me and therefore showing me the true value of money I was receiving for the service. Thank you. ``

Toby Parker - Hampshire.

``The work they have undertaken has been excellent and provided prompt attention to the call out emergency all of which is very reassuring. Alexandra Heating have now installed a new boiler which is working very efficiently.``

Peter Bolger - Hampshire.

``I would just like to say thank you to your two engineers that fixed my boiler last night. They were polite and very professional. I am very impressed with the service I received, will definitely be recommending your services. Many thanks again.``

Chris - Salisbury.

``I wanted a firm who were not only competent installers, but who could also analyse the shortcomings of the existing system and recommend how it could be improved. In the event you have recommended and installed a system which is reducing running costs by two-thirds, so I'm sure I found the right firm!``

Mr Smith

‘We spoke to a number of gas installers and plumbing services companies in the area but received some very mixed advice and questionable customer service; in some cases there was an obvious lack of interest in answering questions about their quotes for the work or how they would tackle some of the issues. When we contacted AHS it was like night and day. They came out to visit with us quickly and took the time to properly investigate our heating issues and to understand our needs and priorities.’

Mr Burgess
