If your boiler stops working in Barnet, first rule out an emergency: if you smell gas or suspect carbon monoxide exposure, leave the property and call the National Gas Emergency Service on 0800 111 999. If there is no warning of danger, check the power, controls and fuel using the boiler’s manual. Do not open a gas boiler or attempt gas work. Renters should report the fault to their landlord or managing agent; owner-occupiers can contact the installer, warranty provider or an appropriately qualified Gas Safe registered engineer.
What should I do if my boiler stops working?
- Check for immediate danger. A gas smell, a carbon monoxide alarm or possible carbon monoxide exposure means stop troubleshooting and follow the emergency steps below.
- If there is no emergency warning, check external causes. Use the appliance instructions to check the power, programmer, thermostat, heating mode and available fuel or prepayment credit. Do not remove the boiler casing.
- Work out who should arrange repair. If you rent, notify your landlord or managing agent. If you own the home, check warranty or installer coverage before booking a repair.
- Choose a suitably qualified professional. For gas work, verify the engineer’s Gas Safe registration and qualification for the job.
What should I do if I smell gas or suspect carbon monoxide?
If you smell gas
Do not investigate the source or try to fix the appliance. Call the National Gas Emergency Service on 0800 111 999. Barnet Council advises opening doors and windows, ensuring appliances are off and turning off the gas at the mains if you can do so safely. Do not operate electrical switches or appliances, smoke or light a flame. Leave the property if needed to make the call safely.
If a carbon monoxide alarm sounds or exposure is possible
Stop using appliances and evacuate immediately. Call 0800 111 999 or the HSE Gas Safety Advice Line, and do not return until you are advised it is safe. Seek immediate medical help. If someone feels unwell or is concerned after possible exposure, contact NHS 111 or a GP; call 999 in an emergency. Possible symptoms include headache, dizziness, breathlessness, nausea, tiredness, chest or stomach pain, confusion and vision problems. They can resemble common illnesses, so do not wait for symptoms if an alarm sounds or exposure is suspected.
A carbon monoxide alarm is not a substitute for regular servicing and may not detect lower-level exposure. Use an alarm that meets relevant standards, and follow its instructions.

What can I safely check before calling an engineer?
Only check external controls and follow the manufacturer’s instructions. A blank or inactive boiler does not by itself establish that the boiler has failed.
- Check whether there is a local power cut, whether the boiler and wall switches are on, and whether a prepayment meter has credit.
- Check whether the heating is set to off or summer mode, or whether the programmer clock or thermostat settings need attention.
- If heating or hot water is missing, check that the relevant programmer setting is enabled. On a combi boiler, the manual’s hot-water temperature and eco or pre-heat settings may explain water that feels cool. For a separate hot-water cylinder, consult the instructions for its timer and temperature controls. Do not change unfamiliar settings or assume one setting works for every model.
- If a breaker trips again after you reset it, do not keep resetting it; contact a registered electrician.
Can I check or adjust boiler pressure myself?
If the display reports low pressure, find the gauge using the boiler manual. Citizens Advice says that when pressure is below 1 bar, you may follow the manufacturer’s repressurising instructions with the heating off and the boiler cool, aiming for 1 to 1.5 bar and closing the valves properly. This is a model-specific procedure, not an instruction to dismantle the boiler. If the pressure changes over the following week, arrange an inspection by a Gas Safe registered engineer.
What if an older boiler’s pilot light has gone out?
Only follow that boiler’s own manufacturer instructions to relight it, and only if there is no gas smell or other warning. If you smell gas or the flame appears abnormal, turn the boiler off, leave and call 0800 111 999.

Could a frozen condensate pipe be the problem?
In cold weather, a frozen external condensate pipe can cause an error code, gurgling or dripping. If the pipe is safely reachable, Citizens Advice describes warming it with a hot-water bottle, heating pack or cloth soaked in hot water. Do not use boiling water, put weight on the pipe or attempt unsafe access. Reset the boiler only as the manufacturer directs; if the fault remains, call an engineer.
Who should arrange boiler repair in Barnet?
If you rent your home
Tell your landlord or managing agent first. Citizens Advice says landlords are responsible for boiler repair or replacement, and tenants should not try to fix the boiler themselves. If an essential repair in a privately rented home is not addressed, Barnet Council may investigate issues including restoring heating or hot water and making dangerous gas appliances safe.
The council asks for your address and contact details, landlord details and information about the issue. Its page says it generally makes contact within five working days, or within one working day if it considers the matter urgent. That is a contact timeframe, not a guarantee that a repair will be completed within that period.

If you own your home
After safe external checks, contact the installer or warranty provider if relevant, or arrange an inspection with a qualified Gas Safe registered engineer. HSE says domestic gas appliances, flues and pipework should be installed, maintained and serviced at least annually by a Gas Safe registered engineer.

If someone vulnerable in your home has no heating
Barnet Council’s safety guidance says Social Care Direct may assist vulnerable residents in an emergency without heating. It lists 020 8359 5000 and 020 8359 2000 out of hours. Check the council’s current contact details before calling, as local numbers can change.
How do I choose a Gas Safe engineer and compare quotes?
Check the engineer’s Gas Safe Register entry and confirm that their qualification covers the work required. Ask to see their Gas Safe ID card when they arrive. Do not rely on registration alone as proof that a proposed repair is appropriate: ask what they have diagnosed and what work they recommend.

Eligible households may be able to get help through ECO or council grants, but eligibility and availability vary. Confirm current local rules and your eligibility before relying on assistance.
Do not choose replacement based on the symptom alone. Establish the diagnosis, boiler condition and age, repair quote and household needs first. A heat pump or biomass system may be an alternative, but installation can take time, require home upgrades and cost more upfront.
Barnet Council says replacing or installing a heating system can involve building regulations. An appropriately registered competent-person scheme may handle notification; emergency boiler repairs do not need advance approval, subject to the applicable rules. Check the requirements for the specific work with the council or installer.
