Rectification of boiler flue and water softener installed by someone else
Customer Service
Quality
Value
I have no hesitation in recommending Just Heat. Professionalism was outstanding along with willingness to be personally on hand when Gas Board engineer was needed to check and increase pressure. Our boiler and Softener had initially been installed incorrectly by another engineer and was non compliant. Major work - including lowering the boiler - was needed to ensure flue was set at the correct angle and the water softener had a bypass. The standard of work has been exceptional throughout.

Justin was friendly, helpful and managed to get the job booked in quickly. Good service and he was also helpful with giving some advice on another project on a separate property. Would highly recommend.

Boiler replacement and decorative radiator install
Customer Service
Quality
Value
I would highly recommend Justin for a new boiler installation. He gave us a detailed quote and then efficiently installed our new Worcester boiler and was professional throughout. I wanted a specific type and size of radiator which he took on board and found the desired product at a good price and even sourced a replacement when the first arrived damaged. During the installation he identified a minor gas leak on the supply to the meter and contacted the gas network on my behalf and had a problem I was unaware of rectified. On completion he clearly explained the new boiler operation on both the boiler itself, the remote controller and the requirements of the boiler guarantee. In all, he was courteous, professional and left the house clean and tidy when finished so if you need heating then you need Justin.

We had an issue with our heating and Justin was incredibly quick to respond, friendly, helpful and had everything sorted in no time at all. We only had to wait a few days for him to fit us into his schedule, and in the meantime he made sure we still had a way of heating our water, which was really appreciated. When Justin arrived, he quickly identified the problem and, even better, had all the parts he needed in his van, so he was able to carry out the repair there and then. We were back up and running in no time. What really stood out was the level of service throughout. Justin even checked back in with us afterwards to make sure everything was still working as it should before sending over his invoice. We’ve used Justin a couple of times now and have always been really impressed. He’s reliable, knowledgeable, friendly and genuinely cares about providing a great service. We wouldn’t hesitate to recommend Justin and Just Heat Services Limited to anyone looking for a trustworthy heating engineer. Great guy and a fabulous service – thank you again, Justin!

Justin came round and carefully reviewed the property and the heating requirements with an air source heat pump. He was very clear about the options and costs. During the installation some unexpected problems were discovered which Justin was clear about and worked around effectively. I have now been left with a modern, future-proofed heating system which I am very pleased with. Overall Justin is a no-nonsense guy and I would recommend him.

Major failure with boiler/heating. JustHeat was recommended by another trusted authorised Worcestershire Bosch engineer. Justin arrived within 1 hour of call and immediately identified the problem - boiler replacement necessary. A written estimate was provided within a further 60 minutes despite the late hour (after 6 pm). The estimate was accepted on condition that the work would be given priority attention . The work was completed within 72 hours of the original call-out. Justin is a highly skilled accredited heating engineer by Worcs-Bosch. His knowledge was clearly apparent and his work left nothing to be desired. Justin is polite, courteous and efficient. We have no hesitation in recommending him to others.

We were advised that our old boiler had to be replaced due to corrosion. Following a recommendation from local tradesmen, Just Heat visited promptly to assess the full setup, taking time to explain issues and advise on the best solution. The work to replace the boiler was scheduled very swiftly. The work was undertaken neatly and efficiently. The operation of the new boiler and the recommended settings were clearly explained. I am happy to recommend Just Heat for your boiler issues.

The work was to install a heat pump, new radiators, replace all hot and cold water pipework . JustHeat were well organised, professional and reliable through the entire works from initial quote to final commissioning and handover. The team worked hard and consistently in the whole house and were very respectful of our personal space and need to continue to live in the house while work was in progress. Unforeseen issues were resolved quickly and we were kept fully informed of progress and plans during the work. The work and the time scale were clearly described to us at the quotation stage. The work was on time and only delayed due to unforeseen additional preparation. We were completely satisfied with the quality, workmanship and professionalism of JustHeat.

I've used Just Heat several times before and the service has always been excellent. On this occasion Justin was booked in for a regular service but our old boiler was unsafe so, with my agreement, was switched off. Justin arranged a quote and fitted my new boiler in a very short time frame. Unfortunately, the gas pressure to our property was an issue so Justin called SGN who scheduled the work. As soon as this was completed Justin commissioned our new boiler that evening. One very happy customer.

Called Justin to look at a relative's boiler that wasn't working and showing fault codes. Another company had quoted £680+VAT to fix it. Justin was very professional and avoided commenting on other heating engineers. I asked him to service the boiler, which he did for a reasonable price, and managed to fix the problem as part of the service. He worked hard to fit the job in the next day as my mum was without heat. He was transparent throughout about what he was doing and what he thought might need done. He was friendly and professional and will always be my first call for any issues in future. Wouldn't hesitate to recommend him.

We had a significant problem with both a failed boiler, which was scheduled for replacement a week later, and the back-up immersion heater. I contacted Justin at 9pm on a Friday and he came round at 2pm on the following Monday to install a replacement immersion element. I was absolutely delighted by all aspects of his service and would not hesitate to recommend him to friends and family.
