Most boilers don't fail overnight, they warn you first. If your boiler is over twelve years old, needs regular resetting, or your bills keep climbing while the house feels cooler, the system is usually working harder than it should.
Watch for these seven signs: a yellow rather than blue flame, banging or kettling noises, radiators slow to warm, hot water that runs lukewarm, frequent pressure drops, visible corrosion or damp around the case, and parts becoming difficult to source.
A repair is often the right call. A leaking valve, faulty diverter or failed thermostat can be replaced for a fraction of a new install, and JGH will always tell you when that's the sensible option. When replacement genuinely is better value, you get clear advice on models, efficiency and warranties before anything is ordered.
New combi installations are usually completed in a single day, with the work area protected, rubbish removed, and all relevant certificates emailed to you within hours of finishing.

Call and describe it, you'll get a straight answer, not a sales pitch.
