Great company to work with from start to finish. All the staff were very friendly and helpful. The engineers left the area very clean and tidy. Would highly recommend. 
 
Kevin Pennock, Colchester - 26th October 2019 
 
James came to repair our boiler expansion tank. We were told it needed replaced but he was able to repair it. 
I was not there but my wife said he was fantastic. Knowledgeable and efficient, polite and tidy. 
And he has solved the problem. 
We were very very pleased with the service provided. 
 
Mr R. Buick, W. Mersea - 15th October 2019 
I would like to add that the customer service by AJS is perfect. From our calls and correspondence, booking, timings, engineer on site (friendly and efficient) to the invoice, was all without fault. And price realistic! 
 
Dave & Ulli Flinn, Great Bentley - 5th October 2019 
 
Very professional and efficient company. Arrangements for the boiler service were easy to make over the phone and the Engineer arrived very promptly at the agreed time. We have confidence in this company to deliver quality services at a reasonable price. The engineer has always been polite and we are pleased to recommend AJS for central heating and boiler works on the basis of work they have done for us over the last 3 years. 
 
Mr R. Penny, Colchester - 4th October 2019 
I would not hesitate in recommending this company. The appointment to quote for an upgrade from solid fuel to oil fired central heating was carried out in a thoroughly professional and sympathetic manner in order to be appropriate for a period property. The whole process and options available to me were discussed very clearly in a way that was easily understood.. The response time to my initial email was surprisingly quick , the appointment was arranged only a few days later and on the day the consultation was unhurried and methodical. The figure quoted to carry out all the necessary groundwork and plumbing was very reasonable, and the extended guarantee and after service on offer was impressive. This company clearly values the importance of a good customer experience. 
 
Julia Cottee, Colchester - 18th September 2019 
 
I have recently contracted your company to install a new Vaillant boiler at our bungalow. Any previous dealings with plumbing companies had been somewhat unsatisfactory. When your fitters Jamie and Jack arrived they introduced themselves and explained exactly what work they would be carrying out. When they started work I was amazed to see that they were not just fitters but professional fitters. They carried out the work to an excellent standard with little mess and at each stage they hoovered up before doing the next part . On completion they explained the controls and when they left the areas where they had worked were as clean and tidy as it was before they started. 
Our thanks to your company and the standards that you and your staff fulfill on a daily basis. 
We will recommend your company to others in the future. 
 
Mr & Mrs Beecham, Elmstead Market - 17th September 2019 
 
Thank you for all your help in sorting our problem with our central heating. 
You took a weight of our mind. Your team was exemplary in their efficiency, their work ethic, 
and in pointing us in the right direction to help us in recovering our heating. 
Without you, we would still be without heating and hot water. 
Thanks again for all your advice and your genuine interest in dealing with our crisis successfully. 
 
Mr & Mrs Drost, Brightlingsea - 10th September 2019

As an elderly customer I have always found this firm courteous, helpful and knowledgeable. They go the extra mile to get a good result. Engineer Mark was kind and tidy, and I felt comfortable that he was doing a great job. 
 
Mrs Wheldon, Kelvedon - 12th October 2018 
 
Extremely impressed with the company from the very first telephone call to the office to the expediency of the work carried out, a new manifold ordered and installed within a week so the underfloor heating could be used. Previously quoted around one thousand pounds by another company but pleased to say total price under 3 hundred. A company that can be trusted and believes in old fashioned customer service. Will definitely recommend this company as nothing too much trouble. 
 
Ms Foster, Colchester - 12th October 2018 
 
A big THANK YOU to Lee for coming to my rescue twice and a third time installing my new underfloor heating system. 
I can’t praise AJS enough, a fantastic team of men. A special thank you to Carol in the office for keeping me informed of what was happening and times and dates of work that was being organised for me. 
It’s definitely a 10 out of 10 for AJS and all the guys and galls. 
Best Wishes Eva 
 
Miss Chapman, Holland on Sea - 4th October 2018 
 
I am writing this testimonial on behalf of my mum. Mum had her boiler serviced on the 28th September and again what a brilliant service . Mark came to do it and he was on time, very friendly, very helpful and very professional. I would recommend AJS to anyone and will certainly use them myself in the future if I need any work doing. So thank you once again. 
 
Liz Clewlow on behalf of Audrey Dean, Colchester - 2nd October 2018

K. Brindle, Colchester - 11th August 2018 
 
 
We were very pleased with the work carried out last week to strip out existing tank within the loft space and the hot water cylinder replacing them with a Joule direct 170 litre pressurised cylinder. The workers worked non -stop and were very thorough , very tidy . Thank you. 
 
Mr & Mrs Prior, Lawford - 23rd July 2018 
 
 
Our company is using AJS for the first time, on a development of 5 apartments, we have found the workmen to be punctual,professional,pleasant & polite, long may it continue. 
 
Clive Harwood - Director - Rose & Harwood Ltd - 21st April 2018 
 
AJS were called when a pressure problem within our boiler had led to a pipe splitting. Another local company were called first, who charged a ridiculous price to assess the problem and I just couldn’t trust them to fix the boiler for anything less than a small fortune. I replaced the pipe myself, but the pressure was still wrong. 
AJS are completely professional, honest and serviced the boiler fully for less than the previous company charged for simply looking at the problem! 
We will be using only them from now on. Great service. 
 
Tony, Colchester - 20th April 2018 
 
Once again used the services of AJS. 
Nothing is ever straight forward but the quality of a Company is when they can solve the problems in a quick and trustworthy manner 
My father in law is very vulnerable but have total confidence in theses guys. 
 
Mr Kearney, Colne Engaine - 21st March 2018 
 
I've used AJS heating and plumbing many times in the last five years and have found them without fail to be responsive, helpful and always willing to try and fit in to our timetable and arrangements. They certainly go the extra mile. There have been many occasions when an urgent matter has cropped up and their willingness to try and create a space in the diary to help us out is a source of considerable reassurance. 
Their skills and professionalism are as good as any we come across. 
 
Jamie Cundall, Concord Property - 20th March 2018 
 
 
The boiler service last Thursday 22/02/2017 could not be faulted. Efficient service and no mess after whatsoever. I would recommend your company to anyone. 
Kind Regards, 
 
P. Dowson, Bradfield - 26th February 2018 
 
The boiler service was prompt and efficient, carried out by a very courteous, helpful and knowledgeable engineer.

Susan Lillywhite, Wivenhoe - 14th February 2018 
 
As I type this it is an opportunity to tell Rob how pleased and impressed my wife and I were by the confident and careful way in which Jamie and Jack carried out the work, leaving the affected rooms clean and tidy. They are to be complimented, and they left the house getting nice and warm. 
 
Clive Pougher, Colchester - 12th February 2018 
 
A J S have just removed a bath and replaced it with a new walk in shower there were a few technical issues with the installation but top plumber Simon took it in his stride and produced a great finish. He also fitted a water softener in the garage, the pipe work was a work of Art. He then replaced a damaged sink in the Kitchen and made a really nice job of it. Would like to thank Rob, Vanessa, Carol, Simon and all the other staff at AJS for their help. I would recommend this company to anybody who wants a 1ST CLASS JOB thanks once again Guys REGARDS ALEX 
 
Alex Cowper, Weeley - 11th February 2018 
 
Engineers arrived on time very friendly, removed old boiler made good the hole in the wall, Installed new boiler in the location we requested. Extremely pleased. Very neat and tidy installation. Explained everything and left the house as tidy as they found it. Great company I would recommend them to anyone requiring a new boiler. or just a service. It`s the second time we`ve used them and would not hesitate in the future... 
 
Paul & Dawn Hancock, Colchester - 9th February 2018 
 
I am delighted with the service I’ve received from AJS. From initial call out to my clanking elderly boiler (which they then managed to keep going for several weeks while I made up my mind which replacement system to opt for), to the superb advice and service they gave in specifying and delivering the new boiler, they have been exemplary. I had to be away on the day they could fit it and I was nervous about what I would come home to find, but you wouldn’t have known they had been in the building except that the house was warm, the water was hot and the new boiler was gleaming on the wall. 11/10 and I can’t recommend them highly enough. 
 
F Brown, Brightlingsea - 9th February 2018 
 
Booked our yearly boiler and gas fire service with AJS, Mark Bilby their engineer turned up on time and was in and out in under 2 hours, very friendly and highly efficient at a great price, would definitely recommend AJS. 
 
Mr & Mrs Farrow - 23rd January 2018
