Is It Time?
When Should You Replace Your Boiler?
Not every ageing boiler needs immediate replacement — but there are clear signals that repair is no longer the right answer. If any of these apply, a replacement is almost certainly the smarter financial decision.
Age over 15 years
The average lifespan of a well-maintained gas boiler is 15–20 years. Beyond that, parts become harder to source, efficiency degrades significantly, and cost-per-repair rises sharply.
Repeated breakdowns
More than two repairs in the past year is a strong signal. Cumulative repair costs typically exceed the cost of a new boiler within a couple of years.
Rising energy bills
Boiler efficiency degrades gradually. If your gas bills have risen without a change in usage, your boiler is likely working harder than it needs to.
Yellow or orange flame
A correctly burning boiler has a blue flame. Yellow or orange indicates incomplete combustion and possible carbon monoxide production — a safety issue requiring immediate attention.
Persistent pressure problems or leaks
Leaks from a heat exchanger, or pressure loss that returns within days, often indicate internal corrosion — rarely economic to repair in an older boiler.
Boiler Types
Which Boiler Type Is Right for Your Home?
We install combi, system, and conventional boilers. The right choice depends on your property size, hot water demand, and existing setup.
Combi Boilers
The most popular boiler type in the UK. Provides central heating and hot water on demand from a single unit — no hot water cylinder or cold water tank required. Compact, efficient, and ideal for smaller homes and flats.
System Boilers
Heats the central heating circuit directly and stores hot water in a separate cylinder. Well-suited to larger homes with multiple bathrooms where simultaneous hot water demand would overwhelm a combi.
Conventional Boilers
Also called heat-only or open-vent boilers. Work with both a hot water cylinder and a cold water tank — the traditional setup found in many older Maidstone properties, particularly period homes in villages like Bearsted and Aylesford.

Pricing
Boiler Installation Cost in Maidstone
New boiler installation in Maidstone typically costs between £2,000 and £4,500 depending on boiler type and brand, output size required, complexity of installation, and whether additional components are needed.
A straightforward like-for-like combi boiler swap is generally at the lower end of this range. A full system conversion with a new cylinder and controls is at the higher end.
