Home › Boiler problems
One list comes before all the others — the gas one. After that, most boiler complaints come down to pressure, power or controls, and you can check all three yourself.
The short version: if you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 — nothing else comes first. Otherwise, check the pressure gauge, the power, and the controls, note any error code, and ring 020 4577 2888 any hour to be connected with a local plumber covering Banbridge.
A gas smell is not a boiler fault to troubleshoot. Put this page down and do these, in order:
Before you pay anyone to visit, five minutes of methodical checking rules out the embarrassing causes. In the newer estates around Banbridge, a surprising number of "dead boiler" calls trace back to a tripped switch or a smart thermostat doing something clever and unhelpful.
The gauge is the boiler's blood-pressure cuff, and the pattern matters more than any single reading.
Older homes near the town centre often run older heating systems that have been extended room by room over the decades — uneven radiators and mystery pressure loss are common there, and both are traceable rather than mysterious to someone with the right kit.
The more of this you can rattle off, the faster and more accurate the advice — and the likelier the right parts are on the van.
Usually, yes. Most sealed systems are topped up through a filling loop underneath the boiler, and the manual shows the steps for your model. Aim for roughly 1 to 1.5 bar when the system is cold. If the pressure keeps dropping again over days or weeks, stop topping up and have the leak traced instead.
Not necessarily. When one works and the other does not, that often points to a diverter valve, a cylinder issue or a control fault rather than a full breakdown. Note exactly which of the two has failed and tell the plumber — it is one of the most useful clues you can give over the phone.
Every manufacturer uses its own codes, so check yours against the boiler's manual or the maker's website rather than a generic list. Write the code down before resetting anything — one reset is reasonable, but repeated resets can hide the pattern an engineer needs to see.
In the UK, anyone working on gas appliances must be on the Gas Safe Register. It is a fair and normal question to ask before gas work is agreed, and you can check an engineer's registration on the register itself. Plenty of jobs around a boiler involve only water — but the gas side is regulated for good reason.
