Jason carried out an extensive service on our boiler. I was pleased that I was able to discuss with him in advance the extent of the boiler service that was sensible, given the age and condition of the boiler. I am pleased with the work he has done, and, as ever, he was pleasant and considerate.

Advice re hot water issue

Each communication with Jason was a pleasure, on the day he understood the delicate issue with my dad having dementia (the water issue in dad's flat). He explained how dad's system worked and was able to diagnose the issue being different water pressures between hot and cold feed and discussed options to fix the issue. Was very kind to dad and myself. The likely fix will involve an electric shower which Jason can't assist with. But if we need any plumbing I'll have no hesitation in calling him.

Jason and his mate, Ricky, fitted a new (wider bore) gas supply to our boiler. The work was promptly completed, they were pleasant and considerate and the new supply is working satisfactorily. This work was intrinsically very disruptive as it involved lifting carpets and some floor boards. What was particularly good was their care in ensuring that our belongings were not damaged and that everything was put back carefully afterwards.

Jason has just replaced my boiler of 20 years. He arrived on time did a very good job and cleaned up afterwards. The job took 2 days and he was a joy to have around during that time whilst allowing me to work from home without too many interruptions. He took me through how to use the boiler as per the manufacturers recommendations and provided all the necessary paperwork related to the boilers warranty.

I called Jason on Friday afternoon as our central heating & hot water system had totally failed. He was able to attend on Saturday morning.

Jason also diagnosed additional issues that may cause problems in the near future and provided verbal estimates regarding the likely costs.

I consulted Jason to provide a second opinion as to whether we really needed to fit wider gas pipe to feed our combi boiler, since this was going to be a relatively costly and disruptive job. Jason agreed to come round and do a number of gas pressure checks to check on this and to give an opinion on whether new pipework was necessary. He came round to do this work, showing the pressure readings to me. He then discussed the results and the different options which might be available to me. This was very useful.

Two Radiators Replaced With Satisfaction

Jason replaced two radiators in our house. Upgraded an old single-panel "angled" style radiator in a bay window with a smaller but higher output "K3" triple-panel. Jason had to add pipework in order to reach the location of the new radiator BUT we wanted the pipework hidden. Couldn't lift floorboards so chose rebated skirting boards to conceal the new pipework. Jason spent great time and attention to detail to ensure the pipework was dressed just right so that when the rebated skirting was fitted the pipes would not be seen. Went the extra mile on the day but stuck with the original quote. Thank you!

Shower Mixer Replacement
Customer Service
Quality
Value
We were introduced to Jason via a painter & decorator whom we have used very satisfactorily over many years. Our need was the replacement of a shower mixer that had eventually succumbed to our hard water. Although the identical product was supposed to be a simple swap over, the process was not as straightforward as envisaged. However, Jason kept us fully informed as to the measures necessary to complete the task which he did successfully. All the while he was anxious not to damage the shower cubicle tiled wall and none arose. Arriving on time, working neatly and providing protection to carpets etc. we were impressed with what he undertook and have - on the basis that he is "gas-protect" - asked him to take over the servicing our gas-fired CH boiler. Personal recommendation, we find, is the only certain means of ensuring that you are dealing with honest traders and Jason stands tall in that regard.

Disinfect cold water tank and pipework and replace faulty pump
Customer Service
Quality
Value
I was very pleased with the way that Jason worked out how to resolve a challenging problem and with the plumbing work itself. There were two existing pumps in the flat. The pump under a walk-in bath had failed, but you would have to remove the bath to be able to replace the pump as it was physically impossible to get to it any other way. He worked out a deceptively simple solution to this: decommission the pump under the bath, modify the pipework in the flat and connect it to a replacement/upgraded pump in the cupboard containing the water tanks. No need for a pump under the bath! The tanks and pipework were also disinfected as the flat had been vacant for some time. The work was done on schedule and to budget. The flat was left in a clean condition.

Jason French was recommended to us by our neighbour. We made contact and arranged a boiler service on our ancient boiler that was beginning to play up. During the visit we discussed making repairs to it but obviously Jason could not guarantee how long they may last in view of our boilers age (20yrs) so we asked him to quote to supply and fit a replacement. He was happy to go with either decision we made. In the end we decided to go for a new boiler as it would be far more efficient and ultimately cost us less to heat our home in the long run. We arranged a mutually convenient date and agreed the quote. The work was completed on time and on the price agreed and Jason guaranteed his installation for 12 months. Very happy to recommend him to others.

I first contacted Jason when British Gas tried to 'rip me off' on renewal of their Home Care Plan. I refused their offer to increase my premium (yet again) and, after reading a most informative article in Which? I found Jason on Trusted Traders. Initially, Jason visited to perform the annual service but after identifying several concerning issues, he quoted for the remedial works and undertook these earlier this week. I cannot recommend Jason highly enough, he is highly knowledgeable, his work is of the highest standard and he is a very clean and tidy worker. Thank you Jason and thank you Trusted Traders.

Jason has kept our old boiler going for a few years, however, after 23 years we decided to finally replace it with a more efficient model. Having discussed our options, he provided clear and easily understood advice with a detailed quotation. His attention to detail is outstanding - For example, being a different size, the new boiler required repositioning, subsequently the route of the old flu differed from the new. Despite not being possible to cut out the brickwork in the conventional way & reuse the core to fill the old flu hole, he approach some builders doing an extension a few doors away and managed to get some bricks of the same colour to cement in to seal the old hole and make good for the new the new flu! We have always found Jason to be polite and courteous and his work to be of a high standard, subsequently we would not have any hesitation to recommend his services.

Repair to underfloor heating system

Firstly, worth pointing out that my own heating and boiler service contract company (who are very well known) does not cover underfloor heating systems which are supposedly too complex for them to deal with. So it was a relief to find a heating engineer who was skilled enough to deal with the issues of my non-working system. Jason suggested two options and the cheaper of the two turned out to be the most practical and efficient solution. He gave me all costs upfront and even tried to reduce them as the job took less time than estimated which I refused on the grounds that experience counts for a lot. This is the second repair that Jason has done for me and very happy to recommend him as trustworthy and skilled trader.

Our boiler had started leaking just as we were going away. Jason told me what to do short term and he came the first day I was back to sort it out. In the end it was quite easy so he sorted that, did a light touch boiler service because he knew he'd done a full one last year and while he was there he fitted a new tap cartridge in the bathroom too. He had a good look at our problematic kitchen tap and we discussed the options and agreed to leave it until it gets worse! That's what I like about him - he doesn't just go ahead but really talks to you about what the issue is and what the possible solutions were. Bill was completely reasonable. Separately Jason has been really helpful with his knowledge on fixing Hive in a house in an area which he does not cover - so something he could never earn money from but willing to help out. Strong recommendation from me.

This is the second time we have used Jason and again he has fulfilled all our expectations by arriving on time, working quickly and effectively, diagnosing the boiler fault and completing the repair and service on our heating, which puts all the previous British Gas service engineers we have had over the years under our now defunct annual contract, to shame. We had ten years of crud built up in the condensate drain pipe, a build-up of carbon deposits in the heat exchanger/burner chamber, a really dirty mess left in the housing, and a leak in the system, in addition to the failure of the fan (the primary fault). I have never seen any previous gas engineer strip a boiler down and clean it all up before reassembling and testing it as part of the service, and remain impressed with Jason's highly responsible customer service ethic.

Jason came round to check a problem which I thought was with the motorised valves. He found they were OK and went on to suggest it was reverse circulation. His diagnosis was quick and he explained the problem clearly.He went on to provide practical solutions which would contain it and hopefully avoid any major work. I have used him before and found him very good and would endorse the positive comments of other reviewers.

We've used Jason's services twice with very good results. The latest was the replacement of a boiler. Jason accurately diagnosed the fault in the old boiler and provided us with options and fully costed estimates for the work to replace it, and move it to a more convenient height. The work was carried out in a very professional and efficient manner. I have no hesitation in recommending Jason as a highly professional and competent tradesman.

Jason responded to our emergency phone call immediately and arrived on time to investigate a small drip from our old boiler; the replacement suggested is an efficient "Which? Best Buy" boiler. Jason communicates well so it was easy to discuss options and get reasons for various decisions. He performed another pre installation check to ensure he ordered the correct parts. Jason and Ricky, who assisted the boiler fitting, were very reliable, honest and friendly. The area was left clean and tidy. Jason only charged for the work completed, as he did not need to use the slate flashing quoted for the boiler flue and did not charge for 2 TRV's as a "gesture of good will". Brilliant service, will definitely use again and can recommend to anyone.

I’ve used Jason on a couple of occasions and the most recent was an all day job installing two new radiators and moving another one to a different room. The job was done perfectly and efficiently and the place was cleaner than when he started! I’ve always found Jason to be easy to communicate with and quick to fix a date for the job. He gives good advice and explains, in detail, all aspects of the job so you know exactly what to expect. He works hard and won’t stop until he’s solved the problem. Jason is a reliable, affable and all round good guy to know. He knows his stuff and I would thoroughly recommend him.

I hired Jason last year to install two cast iron radiators, he drains the system properly and tops it up with the recommended solution needed for the cast iron rads. I’m a perfectionist and a nervous person when it comes to people doing work in my home but Jason is without a doubt a person I can rely on to do a perfect job! He is punctual, trustworthy and a very considerate individual. Due to ongoing home improvements I’ve since had him round 5 more times removing normal rads, fitting new ones etc and still have him booked in to install two more cast iron radiators for me once decorating is complete. I couldn’t recommend him enough... a heating and gas engineer you’ll want to keep the number of for life!

Quick, clear, trustworthy, value for money and the problem is sorted. We had a leaking valve which Jason came and sorted in very short order. He didn't replace it because he didnt know if it was necessary. We agreed to wait and see. He came back to service the boiler a few weeks later and the valve was still dry so we'd avoided an unnecessary repair. All communication was clear and he followed up with an email bill later in the week. I have confidence that the boiler is working well with all the paperwork properly completed. If I have any problems I'll be calling Jason!

We are delighted with Jason's work. He has plumbed in our sink and washing machine, fitted entirely new pipe work and is coming back to service our boiler. From the outset Jason was really helpful, knowledgeable and got stuck in to the task. He was considerate asking if he could play his radio, which he did quietly and he presented options, didn't make assumptions and helped us make informed decisions about other things we needed to have in place in our new kitchen. So lucky to have found Jason and will definitely use him again and have already recommended to others! He was also cautious about his work and implications it had on other things, and came on time first thing in the morning and stayed until the task was completed. There weren't endless tea breaks or disappearing to buy materials during the job, he was prepared and organised, and didn't leave a mess.

The second job Jason carried out for us was tricky because we required him to commission a boiler which he had not himself installed. He inspected the installation and the manufacturer’s manual and required a number of points to be remedied. We arranged for the contractor to carry these out. On further inspection, Jason was still not satisfied and fixed the items himself at a reasonable cost. However he was not satisfied with the gas pressure which was too low for the boiler to operate with optimum efficiency. He called in the National Grid engineer who claimed that the pressure was sufficient for ordinary operation. However Jason insisted that the pressure was still not sufficient. He advised us therefore to register the appliance with the manufacturer and then call in the engineer. We did this and the manufacturers engineer confirmed Jason's diagnosis. National Grid then accepted that the pressure was too low and as a result had to install a completely new supply pipe.
