Unvented hot water system installation

Will and his team installed a new hot water system with a 125ltr Joule cylinder in our loft replacing a very outdated tank system. They completed the work over two days and worked efficiently and tidily. Despite a few problems of installation in an old cottage- these were resolved after some discussion. We were grateful for advice on our existing electrics and are very pleased with the overall result. We will continue to use their services. Thanks again Allstars.

I am so grateful to the guys. After moving into a new house, and a leak on the second day from the outdated immersion tank, contacted Will and we discussed the best system for our set up. He booked us in quickly and the guys got everything sorted out, they even added a new shower last minute. Very helpful, tidy, efficient and an amazing job. Definitely a 5 star (Allstar) service :-)

Supply and Installation of a Joule Unvented, Direct Hot Water System

My 37 year old vented hot water cylinder was leaking. I searched online for a local installer of Unvented, Direct Hot Water Systems as I felt this was the way forward, and found All Star Systems who had all the right credentials. I contacted Allstar Systems by email on Sunday 28 Feb 21. William rang me first thing Monday morning. Within an hour he had found a suitable system, available, and gave me a quotation over the phone for an unvented system and an option for a vented system. I accepted the verbal quotation (written quotation received by email that evening) for the unvented system. William offered to fit it the next day as my system was leaking but I opted for the Friday as it was more convenient for me. Since we were under Covid 19 National Lockdown conditions William and his team arrived with full safety equipment. I showed him the existing installation etc. and then stayed out of their way. The installation was completed with no inconvenience to me and very quickly. William showed me the installation, and explained it to me. It was neat and tidy and no mess. I was very pleased with the work and with the associated benefit of the increased pressure in the system and no roof tank, which had been removed by them. Couldn't be happier. A professional, polite, helpful, and reliable team.

I wanted a good Worcester Bosch service engineer to service our boiler. The reviews for Allstar Systems were excellent so I contacted them and shortly after received a response and a date was fixed. Ashley was here for over 2 hours servicing our boiler. He pinpointed a problem and immediately contacted Will who then spoke to me on the phone. The problem was explained and a solution, to contact Worcester Bosch to ask if they could carry out a one of fix - which they can - was suggested. I was impressed at how patient they were explaining everything and how they were honest and happy to suggest WB carried out the work themselves as it would be more cost effective. I was impressed with their punctuality and how assiduous they were in how they carried out the service. I will be booking them again for next year's service!

New Worcester Bosch Installation
Customer Service
Quality

After extensive research I appointed Will Smith and his team to install a new boiler and service the whole of my central heating system. What clinched the deal for me was the fact that Will identified that I had a dangerous installation previously and the expansion vessel attached to the hot water tank was not secured to the wall, was full to bursting and and the copper piping leading outside was going up hill! No other person coming out to quote had identified this and other problem areas. Allstar in the end was the most expensive quote but I now have a twelve year guarantee from Worcester Bosch. Will and his team worked exceedingly professionally, carried out the work on times and on schedule. I now have a zoned central heating system working very effectively. I was keen to replace the radiators but Will advised if the system was properly cleaned and set up this was an expense I did not need to consider. I appreciated this advise and not spending money where it is not necessary. I highly recommend Allstars Service.

During these difficult times, the Allstar Systems team showed up on time and ready to work, with safety at the for front. The old boiler was removed and replaced with minimal disturbance, the work site was left clean and tidy. At the end of the day, the operating instructions were explained to our satisfaction but felt we could call on them if we had any problems. Very happy with the crew and their work.

Rapid supply & installation of a new boiler, when my old one was caput!
Customer Service
Quality
Value
Having recently moved house, I booked a gas boiler service (on a Tuesday) as this had not been done recently. Sadly, when he arrived (on time, at 8.30am) Ashley discovered a dangerous fault with my old boiler (around 18 - 19 years old) and it was immediately disconnected. Unfortunately Worcester Bosch could no longer supply the broken part. This left me in a cold house - not ideal for early February in East Anglia! Fortunately, Will was able to get hold of a new boiler for me by the next day, and install it on Thursday, only two days after the fault had initially been identified. Will arrived with Banki (an apprentice) just before 9am, and they were both working on the installation (including a power flush of my radiators) until nearly 6pm, with additional help from Ashley for a couple of hours in the afternoon. Furthermore, Banki fitted 'Alladin' self-bleeding auto vents (which I had got hold of earlier) to five radiators on my top floor, which hopefully will save me from bleeding air from those radiators in future. It was very good to have a warm house again, on Thursday evening, and also able to have warm showers again! I can thoroughly recommend Allstar Systems as a reliable company to install gas boilers in the Norwich area. They are accredited installers for Worcester Bosch, and this fact means that the guarantee on my new boiler is for 12 years. Possibly you could find someone else to install a boiler at a cheaper price, but I am prepared to pay for good work.

Thank you for your fantastic and detailed feedback. We’re really pleased we could support you so quickly after your boiler fault was identified. It’s good to hear Ashley was able to carry out a thorough boiler service and correctly identify the safety issue with your older system.

Carrying out a full power flush alongside the boiler installation also helps ensure long-term system efficiency.

We have just had a new Worcester boiler fitted by Will. We’re really happy with the quick and speedy service that him and his team provided. He came on the Tuesday to speak to me as I’ve had issues with only getting warmish water and inefficiency with a 15+ year old boiler. He recommended not to invest to heavily in such an old boiler and that the new one would be much better value. He was then able to fit us in 3 days later and was clean, tidy and very efficient in what he did. Now we have all our heating and hot water issues solved. Would highly recommend.

Despite being the busy holiday period Allstar Systems were extremely responsive to my calls and worked hard to try and accommodate the dates when I was at the property. I was concerned to get in an expert to help fix the cylinder as unvented systems need to be carefully fitted and serviced. All defects were remedied on the day, and necessary parts obtained despite long travel distances. The work was done efficiently and tidily. Very grateful for help and am very confident the appliance is now working properly.

We were really impressed with Allstar Systems (Norwich) Ltd right from the start. They responded quickly to our initial phone message and visited within days. We needed a new, replacement boiler and a new gas supply from our meter to that boiler plus some minor building work to remove a cupboard and make good in the area where the boiler was to be installed. Will was friendly and professional and spent a lot of time going through the options with us. Once we had accepted his quote we were booked in and the team arrived promptly at 08.30am on a Monday, as he said they would. Will, Ash and Bank make a terrific team and obviously know what they are doing and simply get on with it. They worked really hard and were very friendly. We were happy to have them in our home. Will kept us up to date as the work progressed and was good at explaining what was happening and why. The amount and quality of the work that was completed in just two days was impressive. We were very happy with the final result and will have absolutely no hesitation in recommending Will and his team to friends and neighbours and, indeed, other Which members.

I cannot rate Will's work enough. When our original engineer let us down, we went to market and ask for 3 quotes. Whilst Will was the most expensive, I cannot imagine a better system. The cleanliness of his work, punctuality, helpfulness, advice - all 5 star. We now have a system that is a joy to run - I think Will's enthusiasm might have rubbed off on me!

First annual service...

Will and his team installed a new Worcester Bosch Combi boiler etc approx a year ago today at very short notice after I came home from holiday to heating problems. He came round quickly, assessed my needs and took the trouble to explain my options and after we agreed, he smoothly set the wheels in motion. The job was pretty straightforward, but as it progressed it became necessary to also replace an exterior gas pipe, which in turn led to my meter needing to be changed due to a small leak. He called the relevant authorities and got that sorted too. I think Will's mission is to be the very best in his field and in every aspect of my job I don't think anyone could have been better. And I don't want to miss anyone out in my praise either, because ALL his team were incredibly efficient, good humoured, polite, kind, and a pleasure to have in the house. Today after having had the first annual service carried out, my opinions have not changed one iota. Excellent, well-run company, with the principles of times gone by and if I can paraphrase a well- known advert, they not only 'do what it says on the tin' but they know an awful lot about what's inside the tin too!

Will Smith and his team were prompt, professional, and polite. They were also good-natured and hard working, obviously very knowledgeable and helpful with a plumbing query not directly related to the gas boiler installation they were working on. Will explained what he was doing and why, and helped us decide on the best options of our installation.

Will and his team replaced my mother in law's ancient boiler, replaced leaking pipework and installed her new cooker this week. Will came to her house on a Saturday afternoon to see what needed to be done and provided a very reasonable quotation that same evening, which we accepted and a date was arranged for the work to start. Due to my mother in law's deafness we had joined her at her house to explain what she wanted done. Will was very understanding and kept me upto date by phone when the work was in progress and when a bit of additional work needed to be done (the valves needed to be changed on the radiators before the system could be flushed) as mother in law probably didn't hear a lot of what she was asked. Mother in law is very happy with the work. She had been worried about the disruption, but Will and his team were tidy, polite and did the work in a couple of days. She is very happy to have heating, hot water and a working cooker again as, due to the leaks, the gas had been turned off for while. Would certainly recommend Allstar Systems.

Allstars were very helpful, efficient and always were able to give useful advice. They did a great job, and tidied up afterwards. I will be using them again.

Had a new boiler, cold water mains boost vessel and a water softener installed. The quote was very detailed and fair, breaking down the individual cost of each aspect. William and his team arrived promptly, were thorough and very conscientious. William is very professional and meticulous. Puts you at ease the minute you meet him and obviously very good at what he does. Will be using Allstar Systems for all heating needs going forward and will be recommending them to all I know.

Will and his team replaced a boiler and I can honestly say that there was not a single problem with the work throughout. Will worked an incredibly long day to get the boiler up and running on the first day so we could have heat in the house. His knowledge of the boiler system is incredible and I would definitely recommend him to anyone.
