What Is a Combi Boiler?
A combi (combination) boiler provides heating and hot water on demand, directly from the mains — meaning you don’t usually need a hot water cylinder or cold water tank.
Combi boilers are a popular choice across Leeds because they’re:
- Efficient and cost-effective to run
- Compact and ideal for smaller spaces
- Great for instant hot water (mains pressure dependent)
- Often cheaper to install than systems requiring tanks/cylinders
Not sure if a combi is right for your property? We’ll talk you through the options clearly and recommend what suits your home — not what costs the most.

Combi Boiler FAQs
Do I need a combi boiler?
A combi boiler is often ideal for small to medium homes with 1–2 bathrooms and good mains pressure. If you have multiple bathrooms used at the same time, a system boiler may be better — we’ll advise honestly.
How long does a combi boiler installation take?
Most combi replacements can be completed within 1 day. Conversions can take longer depending on pipework changes and system alterations.
How often should I service my combi boiler?
We recommend once a year to help maintain safety, efficiency, and warranty requirements.
Why does my combi boiler keep losing pressure?
This can be caused by leaks, a faulty expansion vessel, radiator issues, or pressure relief valve problems. We can diagnose and repair the cause.
Do you offer warranties on new combi boilers?
Yes – we can offer warranties up to 12 years on eligible installations (brand/model and terms apply).
What should I do if my boiler breaks down?
Check pressure, thermostat settings, and reset (if safe to do so). If it still won’t run, contact us and we’ll advise and arrange a repair visit.
