Emergency call-out
No heating or hot water in Macclesfield
In short
Losing heating and hot water in cold weather is treated as urgent, particularly where there is an elderly resident, a young child or anyone unwell in the house. Two checks are worth doing before the call: the boiler's pressure gauge, and whether the programmer and thermostat are actually calling for heat. Everything past that is a Gas Safe job.
Also called: boiler not working · no hot water · heating not coming on · boiler locked out
Signs you need this
- No hot water at any tap, or hot water but no heating
- Boiler showing a fault code or a red light
- Pressure gauge reading zero or below 1 bar
- Boiler firing then cutting out repeatedly
- A gurgling boiler and no output after a hard frost
A surprising share of no-heating call-outs are not faults at all. A programmer that has lost its time after a power cut, a room thermostat turned down by somebody else in the house, a smart thermostat whose batteries have gone, a boiler that has locked out and only needs a reset. Those are all worth ruling out first — not because a plumber minds attending, but because you would rather not pay for it.
The next check is the pressure gauge on the front of a sealed system boiler. It should sit around 1 to 1.5 bar when the system is cold. If it is on or near zero the boiler will refuse to fire, and the reason it is at zero is almost always a leak somewhere — at a radiator valve, on a joint, or through the pressure relief valve. Topping it up gets the heating back on; finding why it dropped stops you doing it every fortnight.
If the boiler is showing a fault code, note it down before resetting. The code tells the engineer whether they are looking at ignition, flame sensing, a diverter valve, a blocked condensate or a failed pump — and that decides which parts they bring. Repeated lockouts on the same code should never simply be reset over and over; a boiler that keeps locking out is protecting you from something.
One genuinely seasonal fault: a frozen condensate pipe. Condensing boilers drain acidic condensate through a small plastic pipe, and where that pipe runs outside it can freeze solid in a cold snap, backing water up and locking the boiler out. Thawing it with a hot — not boiling — water bottle or a cloth soaked in warm water often restores the boiler in minutes. If it happens every winter, the pipe wants re-routing or upsizing, and that is a permanent fix worth having.
Everything beyond the reset button on a gas appliance is legally restricted work. Any repair inside a gas boiler, on gas pipework or on a flue must be done by a Gas Safe registered engineer, and you are entitled to ask for the card. It is not paperwork for its own sake: badly done gas work is the one plumbing failure that kills people.
Cold weather is not evenly distributed across this patch either. The high ground east of the town runs several degrees colder than the plain, and frost sits longer at altitude. If you are in the upland villages — Langley, Sutton Lane Ends, Rainow, Kerridge — a boiler outage in January is a more urgent problem than the same outage in the town centre, and it is treated that way.
What the job covers
- Checking controls, programmer, thermostat and power supply first
- Reading and interpreting the fault code
- Repressurising the system and finding out why the pressure dropped
- Thawing and re-routing frozen condensate pipework
- Gas Safe diagnosis and repair of the boiler itself
- An honest verdict when a boiler is beyond economic repair
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your plumber has to honour it. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
Can I repressurise the boiler myself?
Usually yes — most sealed systems have a filling loop, either a braided hose with two valves or a built-in key. Open it slowly until the gauge reads about 1.2 bar cold, then close both valves fully. If you are doing it more than once or twice a year, there is a leak that needs finding.
Is no heating really an emergency?
In summer, no. In cold weather with an infant, an elderly resident or someone unwell in the house, yes — and it is prioritised accordingly. Say so on the quote form, because it changes where the job sits in the queue.
