Will and his team were totally professional in all that they did.
Worked solidly for 2 weeks to complete all of our works, including some late nights.
Will shared his great knowledge and advised us with patience and total understanding of our needs.
Work completed to a very high standard and all emails and phone calls answered promptly.
Nothing was too much trouble for this highly recommended team.
Will definitely call on these guys again for all our plumbing and heating needs.
Thank you so much Will, Ash, Banki and Luke for all of your hard work; it’s really appreciated.

I would 100% recommend this company for all of your plumbing needs! We have used them on a couple of occasions and most recently they really did save the day (we had a boiler leak on NY’s Day!!) Ashley could not have been more helpful and responded instantly despite it being a bank holiday. Allstar Systems are reliable and are incredibly reasonably priced. Ashley took safety very seriously which was very reassuring during the pandemic. 5 stars from me, I couldn’t recommend enough!!

I highly recommend William and his team who replaced our old boiler with a Worcester Combo & re-sited it from the kitchen to the mid loft space doing a very clean & tidy job. How they managed to remove the redundant fiberglass tanks & associated pipework from a very narrow upper loft space without any mess or damage is still a mystery to me. William is extremely knowledgeable and took the trouble to explain how to get the best out of my new boiler. He thoroughly tested the new system and showed me that all the results were in specification. I had William & his team back to re-site the underground

I accepted a quote from all star systems which included a full bathroom installation and new systems boiler with unvented cylinder. Will and his team came in and completed the work in time and in a organised professional manner. Allstars quotes were very competitive and because of this I will be receiving a quote for my extension in which I'm thinking of having underfloor heating.
