Boiler Installation in Medway
If your boiler is over 10 years old, costing more to run each winter, or breaking down when you need it most, a new boiler installation could cut your heating bills by up to 30%. Advance Medway supplies and fits new boilers across Chatham, Rochester, Gillingham, Strood, Rainham, and every Medway town in between.
When Do You Need a New Boiler?
There are several clear signs that your boiler is nearing the end of its working life. Knowing what to look for can save you from an unexpected breakdown in the middle of winter.
- It is over 10–15 years old. Older boilers operate at 60–70% efficiency compared to 90%+ for modern A-rated condensing boilers. That means up to 30p of every pound you spend on gas is wasted.
- Repair costs are mounting. If you have spent more than £300 on repairs in the past 12 months, a replacement is often more cost-effective.
- It keeps breaking down. Frequent breakdowns are a sign of worn-out components. Parts for older models become increasingly difficult to source.
- Your energy bills keep rising. Even if your boiler appears to work, declining efficiency shows up directly on your gas bill.
- You have uneven heating. If some rooms heat up while others stay cold, the boiler may no longer be producing enough output for your system.
- It makes unusual noises. Banging, kettling, or gurgling sounds can indicate limescale build-up or internal component failure.
Types of Boiler We Install
- Combi Boilers The most popular choice for homes in Medway. A combi boiler provides both central heating and hot water on demand, without the need for a separate hot water cylinder or cold water tank. Ideal for smaller to medium-sized homes with one bathroom.
- System Boilers If your home has two or more bathrooms, a system boiler paired with a hot water cylinder delivers a stronger flow of hot water to multiple outlets at the same time. The cylinder stores hot water so you are not waiting for it to heat up.
- Conventional (Regular) Boilers These work with both a hot water cylinder and a cold water storage tank, usually found in the loft. They suit older properties with existing pipework designed for this type of system, and are a good option if you do not want to change your entire heating setup.

Our Process
Getting a new boiler installed with Advance Medway is straightforward. Here is how it works:
Free Home Survey
We visit your property to assess your current heating system, measure your hot water demand, and discuss your preferences. There is no charge and no obligation.
Written Quote
Within 24 hours of the survey, we provide a detailed written quote that covers the boiler, all materials, labour, and any additional work such as upgrading pipework or relocating the boiler.
Installation Day
On the agreed date, our Gas Safe registered engineer arrives on time, protects your floors and furnishings, and carries out the installation. A standard like-for-like swap typically takes one day. System changes or boiler relocations may take two to three days.
Testing and Commissioning
Once fitted, we pressure-test the system, check all connections, run the boiler through its full operating cycle, and ensure your heating and hot water are working properly.
Paperwork and Warranty
We complete your Benchmark commissioning checklist, register your boiler warranty with the manufacturer, and submit your building regulations notification. You receive all documentation before we leave.
