Which boiler is right for you?
The right boiler depends on how many bathrooms you run at once, how well your home is insulated, and whether you have room for a cylinder. Ignore the "everyone should have a combi" advice.

Pros
- Compact — fits in a kitchen cupboard
- No cylinder or tanks
- Hot water on demand
Cons
- Flow rate drops with two showers at once
- Not ideal for very large homes
System boiler

Which smart control should I fit?
The honest answer: it matters less than good scheduling. Any of these four, set up properly, will save 8 – 15% on your gas bill. We fit whichever you want and we don't take manufacturer kickbacks — so the recommendation stays yours.
Google Nest
Best for households already in the Google ecosystem — genuinely learns your schedule.
Hive (British Gas)
Simplest app, widest engineer familiarity, good for renters and second properties.
Tado°
Room-by-room control with smart TRVs — best return if you have unused rooms.
Honeywell evohome
Serious zoning — big houses, multi-storey, whole-home schedules per room.
Warning signs your boiler needs attention
Pressure won't hold
Losing pressure every few days points to a leak somewhere on the system — often a rad valve or the expansion vessel.
Yellow flame, not blue
Any flame that isn't crisp blue is an urgent Gas Safe callout — it can mean incomplete combustion and carbon monoxide.
Kettling / rumbling noises
Usually limescale build-up in the heat exchanger. Left alone it kills the boiler; caught early it's a flush.
Radiators cold at the bottom
Sludge sitting in the system. A powerflush restores flow and cuts your gas bill.
Recurring error codes
Fault codes reset by design — if the same one is back within a week, it needs a proper diagnosis, not a reset.
Rocketing gas bill for no reason
Efficiency drops long before a boiler dies. A service often pays for itself in a winter.
How to reset a combi boiler (safely)
Only reset once. If the fault comes back, stop and book a diagnostic — repeated resets on the same fault code destroy components.
- 1
Check the pressure gauge. If it's below 1.0 bar, top up using the filling loop until it reads 1.2 – 1.5 bar (boiler off, taps closed).
- 2
Note the fault code on the display, then press and hold the reset button (usually a flame icon) for 3 seconds.
- 3
Wait 30 seconds. If the boiler fires, run a hot tap for 60 seconds to confirm hot water and heat.
- 4
If the same fault returns within 24 hours, stop resetting — book a diagnostic. Repeated resets on the same fault damage components.
