We recently had a completely new heating system installed by L.E Heating, and we couldn’t be happier with the service from start to finish. Lee and his team were fantastic throughout the whole job. Because of the flooring in our bungalow there were a few challenges along the way, but Lee kept us fully updated at every stage and clearly explained any issues that came up. He also talked us through the different options available so we could decide on the best way forward, which we really appreciated. Communication was excellent the entire time, and Lee and his team worked efficiently and professionally. The work was completed to a very high standard and everything was left clean and tidy once the job was finished. It’s clear Lee takes real pride in his work and in making sure customers feel informed and confident about what’s being done. We would highly recommend Lee and his team at L.E Heating to anyone looking for reliable, honest, and skilled heating engineers.

I thought the underfloor heating was leaking. Lee from LE Heating came the next day. Examined, checked the boiler, manifold and outside. Ruled out a leak. Diagnosed air bricks being too low/patio too high so outside water dampness or ingress. Explained clearly the problem. Prompt, professional and helpful. Recommended.

Finally we have found a heating engineer who looks beyond the obvious and spots what oters have not noticed - eg non-return valve upside down. Super efficient team and a pleasure to do business with Lee, Neil and Monika in the office.

Boiler developed an issue overnight that I could no fix, so no heating or hot water. Called LE Heating first thing and Lee was around by 10am. Diagnosed fault and gave phone number for Vaillant warranty (they only speak to property owner) with description of fault. Outcome is Vaillant turning up today to replace pump. Without Lee's comprehensive understanding not only of Vaillant boilers, but also of Vaillant UK as a business, it is likely this would have taken at least a week to resolve. Excellent customer focus and knowing best way to get fixed

I had a frustrating experience with this heating company. After my boiler displayed an L9 error code, they replaced the PCB, claiming a 1-year warranty. However, just three days later, the L9 code reappeared. The engineer suggested a faulty harness and asked me to pay for a new one. My heating engineer friend raised concerns about whether the new PCB was truly brand new or refurbished. When I contacted the company with this information, they insisted that only a manufacturer's certificate would confirm the PCB was faulty and refused to honor the warranty without one (even though I had taken a photo of the boiler as evidence and checked the manufacturer's manual, which stated that a faulty PCB was the ONLY reason to display the L9 code). Weeks later, they offered to replace the PCB again but wanted to take the original one to inspect it, warning I'd be charged if it wasn't faulty. This lack of transparency and unwillingness to honor the warranty left me feeling doubtful and frustrated.

Featured Questions About Boilers & Installation

Frequently Asked Questions

If you are considering a new boiler installation, these frequently asked questions should help you better understand the process and whether it could be right for your property.

If your boiler frequently breaks down, is unable to adequately heat your home, or is a costly repair issue, then it might be much cheaper to just have a new boiler installation. Compared to the old ones, today's boilers are much more energy efficient and will save you money while also giving you dependable heating and hot water at the same time.

Over the past 20 years, we have served domestic and commercial customers. We offer you a fixed quotation price with no hidden charges, and each of our jobs will be done by professionally trained heating engineers only. After finishing the service, we'll make sure you understand how to use the new system, provide all relevant documentation, and leave your property clean and tidy.

Yes, definitely. A modern energy-efficient boiler uses fuel more effectively than older models. This helps your heating system to perform better while reducing energy loss. Choosing the right boiler size and a professional installation gets the best possible performance from your new heating system.

Boiler installations will probably be complete within a day. Nevertheless, should one need to change the boiler type, move its location, or make some parts of the heating system upgrade, it might need more time. After the technician has done an initial assessment, you can get to know how long it is expected to take.

At LE Heating, every boiler installation follows a simple four-step process. We begin with a property inspection, provide a transparent fixed-price quote, complete the installation, and finish by explaining your warranty and system controls. A methodical procedure such as this guarantees that your whole process will be hassle-free and smooth.
