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.Posted on Google![]()

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.Posted on Google![]()

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.Posted on Google![]()

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 fixedPosted on Google![]()

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.

LE Heating provides central heating repair and installation services for homes and commercial premises in Welwyn Garden City and the surrounding areas. Our experienced engineers can inspect your existing system, identify any faults and recommend the work required. Contact LE Heating to arrange an inspection and receive a fixed-price quote.
The cost of central heating installation depends on the size and layout of the property, the type of heating system selected, the number of radiators required and whether new pipework or controls need to be fitted.
Online averages can provide a rough guide, but an inspection is needed to produce an accurate price. LE Heating will assess your home or commercial property before providing a clear, fixed-price central heating installation quote, helping you avoid unexpected costs.
A central heating installation normally begins with an assessment of the property, its existing heating system and the heating and hot-water requirements of its occupants. The engineer can then recommend a suitable system and agree to the specification before installation begins.
LE Heating follows a straightforward four-step process:
Contact LE Heating to discuss a new central heating installation for properties in or around Welwyn Garden City.
The installation time depends on the scale and complexity of the project. Replacing a boiler or individual heating components may be completed within a day, while installing a complete system with new radiators, controls and pipework will take longer.
Access, property size and the condition of the existing system can also affect the schedule. After inspecting the property, LE Heating will explain what the installation involves and provide an estimated timeframe alongside the fixed-price quotation.
Common central heating options in UK properties include combi boilers, system boilers, and conventional or heat-only boiler systems. Low-carbon alternatives such as air source heat pumps may also be suitable for some homes and commercial buildings.
The best option will depend on the size of the property, the existing pipework, available space and the amount of heating and hot water required. LE Heating can assess these factors and recommend a suitable system for your property. Contact our team if you are unsure which type of central heating installation you need.
There is no single heating system that will be the most efficient choice for every property. Efficiency depends on factors including the building’s size, insulation, existing pipework, heat source, radiator capacity and heating controls.
A correctly sized modern boiler or heat pump, suitable radiators and effective controls can all help reduce wasted energy. LE Heating can inspect your property and discuss the available options, helping you choose a central heating system suited to your heating requirements and budget.
Common signs that a central heating system may need professional attention include:
These symptoms can have several possible causes, so professional diagnosis is important. If you notice any of these problems, contact LE Heating to arrange a central heating inspection.
Repair may be the most practical option when the fault is isolated, and the existing system remains reliable, safe and efficient. Replacement may offer better long-term value if the boiler or other components are old, repairs are becoming frequent, replacement parts are difficult to obtain, or the system no longer heats the property effectively.
LE Heating can assess the condition of your central heating and explain the available repair or replacement options. Our team will recommend the work required and provide a fixed-price quote, allowing you to make an informed decision.
A central heating boiler will commonly last around 10 to 15 years, although installation quality, usage and maintenance will affect its lifespan. Radiators and pipework can last considerably longer but may eventually develop corrosion, leaks or build-up.
Regular servicing and prompt repairs can help keep the system working safely and efficiently for longer. If your heating is becoming unreliable or you are unsure whether it needs repairing or replacing, LE Heating can inspect the system and recommend the appropriate next step.
