Professional Back Boiler Repairs, Servicing & Replacement Advice

Although modern combi boilers have become increasingly popular, many homes across Heathrow and the surrounding areas still rely on traditional back boiler units. At LS Gas & Heating Ltd, we continue to provide professional back boiler servicing, repairs and replacement advice, helping homeowners keep these older heating systems operating safely and efficiently.

Our experienced Gas Safe registered engineers understand the design and operation of older heating systems and can diagnose faults, carry out servicing where appropriate and provide honest advice when a repair or replacement is the best option.

Whether your back boiler has stopped working, needs an annual service or you’re considering upgrading to a modern boiler, we’re here to help.

What Is a Back Boiler?

A back boiler is a type of gas boiler installed behind a fireplace, usually hidden behind a gas fire or decorative front. Popular in homes built between the 1960s and 1980s, these systems provide heating and hot water while remaining largely concealed within the chimney breast.

Although many back boilers continue to operate reliably, they are generally less energy efficient than modern condensing boilers and may become more difficult to repair as replacement parts become harder to source.

If your property still has a back boiler, regular servicing and maintenance are essential to keep it operating safely.

Should You Repair or Replace Your Back Boiler?

One of the most common questions homeowners ask is whether they should continue repairing an older back boiler or replace it with a modern heating system.

In many cases, repairing a back boiler is still worthwhile if:

  • The fault is minor.
  • Replacement parts are available.
  • The boiler is otherwise operating safely.
  • Repair costs remain reasonable.

However, replacement may be the better option if:

  • The boiler is becoming unreliable.
  • Replacement parts are difficult to obtain.
  • Energy bills are increasing.
  • Frequent repairs are required.
  • You want improved efficiency and modern heating controls.

We’ll always provide honest advice based on your individual circumstances, allowing you to make an informed decision.
