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.

After having a disappointing engineer from another company who hadn’t got a clue, Mis diagnosed the problem, left me with a dripping tap and no water out of one tap! My neighbour recommended Just Heat. What a difference! Justin was quick, clean , tidy , knew his stuff and got my heating and hot water going within the hour. Polite and cheerful I would happily recommend him to family, friends and anyone else who needs help from someone reliable and professional.

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.

Justin came to our rescue after we were experiencing issues with our nest system. We live in quite a remote area which means the WiFi signal is not always its best. Justin installed a new hive system but kept it WiFi free. It might seem like a step back, but a reliable, schedule planned heating system is what we need and Justin understood that. He also found another fault with our boiler and sorted that, he is knowledgeable, reliable and reasonable with his pricing. We would not hesitate to go back to Justin in the future and hope he will been a contractor we can call on from now on. Don’t hesitate in giving him a call.

We identified a fault with our gas fire. After isolating our gas supply we contacted Just Heat and Justin came round straight away. He made the appliance safe, tested the boiler and hob, and we had the heating back on in no time at all. Could not ask for more. We are always very happy with his service over the years and his knowledge, as he take the time to explain everything clearly.

I first heard of Justin after he had installed a new boiler for my daughter. I was having a lot of trouble with the boiler supplier and Justin moved the controls down into the cupboard for me which were originally up in the loft and difficult to get to. When my old control panel went wrong I was able to send Justin various photos of the gauge and he could talk me through it which put my mind at ease. Justin came to service my boiler today. I then decided to update my system and he was very patient showing me how to download the Hive App on my phone, which wasn't straight forward due to varying email addresses. I would thoroughly recommend Justin for all your heating needs, it really gives me peace of mind.

My thermostat gave up the ghost a few months ago and Justin coaxed it back into life, warning it was on its last legs. When it packed up again his response time, professionalism and ability to tailor options to my needs were exceptional. Plus he never makes you feel like a numpty which is unusual. He installed my boiler about eight years ago and I've never had a problem with it since.

Justin certainly lived up to his previous reviews. He was very helpful and informative in helping us decide how to upgrade the system in the bungalow we bought. He worked very professionally on the installation, taking time to do the work to a high standard without shortcuts. He was punctual and worked full days to get the job done. At the end of the work he took the time to explain all the controls and how they worked. After completion, he made sure all the work areas were tidy and clean Would definitely recommend and use again.
