What a wonderful service. I was so impressed with the two engineers that attended. They arrived on time, were friendly, professional and did a great job. On top of all that very good value. I will definitely be using them again.

After experiencing a terrible experience with a dubious online company who deceived me, overcharged me, did not fulfill their job and disappeared, I was looking for a good and honest plumber to fix the problem of my hot water cylinder. One of my friends recommended Joe and his company to me and after contacting Joe and talking to him I immediately felt I was in good hands. Joe is very professional, kind, reliable and respectful. He is honest and a brilliant plumber. He identify the problems and he provided immediate fix at the first visit. The amount paid for Joe’s work was very reasonable (I was expecting more!) and certainly his work ethos, transparency and knowledge are worth more! I would implicitly recommend Joe to anyone looking for a plumber. I will certainly be using his company in the future for any plumbing issues in my property.

We've used Joe for quite a few years now. He does our annual boiler and gas fire service plus we also used him when we had a leak under our bath and more recently to replace all of the valves on our radiators. We are more than happy with the services that Joe provides. He's responsive, honest, friendly and courteous. I find that it can be difficult to get good tradespeople at the moment, especially ones that are responsive and I'm so glad that we found Joe a few years ago and can rely on him!

Joe did a great job installing my new boiler, quickly, reliably and efficiently. He provided an excellent service, even sending me a how to video (twice after I lost the first one). He puts a lot of care into the job and I would highly recommend him!

I've been using Joe for years - since he was a one man band. He's serviced our own boiler, as well as carrying out service and safety maintenance on our rental property. He's always been honest, good value and very reliable. He's also a genuinely lovey guy. I've recommended him to lots of people over the years. It's been a pleasure watching his business grow over the year and he deserves every success.

Common Questions

Increasing your boiler pressure is a simple task that involves a few steps. First, you want to make sure the boiler is switched off and has had time to cool down. Then, find the filling loop, which is often found on the underside of your boiler. Carefully turn the valve to allow water into the system. As the water flows, you’ll want to keep an eye on the pressure gauge; a typical pressure reading is usually around 1-1.5 bar. Once you’ve reached the correct pressure, make sure to close the valve and then you can switch the boiler back on. If at any point you’re not sure about something, we recommend getting in touch with a professional like Heatplex to avoid causing any damage to your boiler.

Nest and Hive are two leading brands when it comes to smart thermostats, each offering its own unique advantages. The Nest thermostat stands out with its rotating dial and digital display, and it has the ability to learn and adjust your heating based on your habits. Hive, on the other hand, is controlled using buttons and provides a simpler display, and unlike Nest, it requires manual scheduling. Regardless of these differences, both thermostats can be controlled remotely through their respective apps and are compatible with most heating systems. However, it’s important to note that the specific functionalities can depend on the particular model of thermostat.

The duration of a boiler installation can greatly depend on the complexity of the job. For instance, a straightforward swap of an old boiler for a new one generally takes between 1-2 days. However, if the installation is more complex, such as when changing the type of boiler or moving it to a different location, it may take 2-3 days. At Heatplex, we are committed to carrying out all installations as efficiently as possible to reduce the amount of disruption to your home.

A Gas Safety Certificate, also known as a Landlord’s Gas Safety Record, is a legal document that landlords in the UK are required to have. It includes a thorough check of all gas appliances, fittings, and flues in a rental property to ensure they are safe to use. This involves making sure that the appliance is operating at the correct pressure, carrying out a tightness test to check for any gas leaks, checking that ventilation is adequate, and verifying that safety devices are working properly. These checks must be carried out by a Gas Safe registered engineer. At Heatplex, we provide comprehensive services for obtaining a Gas Safety Certificate, giving landlords the peace of mind they need.
