Combi boiler replacement by a Gas Safe engineer
Our Gas Safe engineer team has experience replacing existing combi Boilers and assessing whether a new model is suitable for your home. Before recommending a boiler, we look at your water pressure, gas supply, property size and how your household uses heating and hot water.
A combi boiler can be a practical choice for homes with moderate hot water demand, particularly where space is limited and there is no need for a separate hot water cylinder. We provide straightforward advice, professional installation and dependable aftercare from start to finish.
A replacement can improve efficiency and reliability, while a correctly sized boiler can help provide consistent heating and hot water without unnecessarily increasing running costs. Our certified approach means you receive clear recommendations based on your property rather than a one-size-fits-all solution.

Is a Combi Boiler right for your home?
A combi boiler heats water directly from the mains whenever a hot tap or shower is turned on. Unlike a regular or system boiler, it does not store hot water in a separate cylinder, and it does not require a cold-water storage tank in the loft.
This makes combi boilers particularly useful for homes with one or two bathrooms and moderate hot water usage. However, if several showers or taps are regularly used at the same time, the available hot water flow can become limited. In those circumstances, a system boiler with an unvented cylinder may provide a better solution.
We check your requirements before recommending a replacement. If a combi isn't suitable, we'll explain the alternatives.
Replacing a regular or system boiler with a Combi Boiler
If you currently have a regular or system boiler with a hot water cylinder, you may be able to convert the heating system to a combi. Removing the cylinder and, where applicable, loft tanks can free up useful storage space.
A conversion needs to be assessed carefully. We check the existing pipework, gas supply, flue route and water pressure before confirming whether the property is suitable. Where the work involves an unvented cylinder or wider heating changes, our G3 qualified engineers can advise on the appropriate approach.
Based in Gillingham, Dorset, our certified team can also help if your assessment shows that a cylinder-based system would be more appropriate than a combi.
