Smell gas, suspect carbon monoxide or hear a CO alarm?
If you smell gas or suspect carbon monoxide, leave and follow the emergency action below before arranging a boiler visit.
Smell gas: Avoid flames and electrical switches. Ventilate and turn off the gas supply at the meter only if safe, without delaying your exit. Call the National Gas Emergency Service on 0800 111 999 from outside.
Suspected carbon monoxide or a CO alarm: Get everyone into fresh air. For suspected exposure or symptoms, seek medical help through NHS 111, or 999 for serious symptoms, then contact 0800 111 999. Never delay medical help for the gas call.
Carbon monoxide has no smell. Treat an alarm as real, do not reset or investigate the boiler, and do not re-enter until advised it is safe.
Worcester boiler repair in London
Worcester boiler repair starts with assessing the fault and identifying what work the appliance needs. No heating, no hot water, leaks, falling pressure and persistent display warnings are useful descriptions, but they do not identify a failed component by themselves.
We assess repair options before discussing replacement. Tell us when the problem started and whether it affects heating, hot water or both. Our boiler repair in London page explains the wider repair service.
Worcester Bosch boiler faults: what to report and what happens next
Report what your boiler is doing, its exact model and the full display message. Use observations you can make safely; never open the boiler casing or work on gas. These details help prepare a repair assessment:
- No heating or hot water: Report when both stopped and what the display shows. The appliance, controls and heating system may need assessment. Arrange a fault visit rather than assuming the whole boiler needs replacing.
- Hot water or heating only: Explain which function works and whether the failure is continuous or intermittent. The engineer needs to assess how the appliance and controls respond. Include this distinction when booking.
- Pressure repeatedly falling: Report the visible reading, how quickly it falls and any previous top-ups. The cause needs investigation across the boiler and system. Arrange assessment instead of repeatedly adding water.
- Visible water or unusual noise: Describe the visible location or sound and when it occurs, without touching wet equipment or removing panels. The source and safety implications need assessment. Report these details when requesting the visit.
- Persistent fault display: Give the model, full code including additional digits, and whether it returns. A code is not proof of a failed part. Arrange assessment and.
When repair needs a replacement assessment
Replacement becomes relevant when inspection shows that repair may be unsuitable. Age alone is not a reason to replace a boiler; the recommendation should explain the findings and available options.
The assessment considers:
- Safety findings and whether the appliance can be repaired safely.
- Confirmed availability of the parts needed for this particular model.
- Previous repairs and the pattern of recurring failures.
- The proposed repair cost alongside the boiler’s condition and age.
Identify your Worcester Bosch model before booking
The full Worcester Bosch model name helps identify the correct instructions and confirm the scope of the visit. Look in existing paperwork, the user manual or safely visible external identification. Never remove the casing to find a label.
A range name alone may not identify the exact variant. Read out the full designation, including any letters or numbers, and mention whether you need a repair or scheduled service. Have previous service records available if you have them. If you cannot identify the model safely, say so when calling rather than trying to dismantle anything.
Worcester Bosch boiler servicing: what the visit includes
A Worcester Bosch boiler service follows the maintenance instructions for the exact appliance model. The model and service history determine the relevant checks and maintenance, so a service should not be treated as an identical procedure for every boiler.
The scope follows the applicable instructions and includes:
- Identifying the appliance and reviewing available service history.
- Checking the appliance, flue and ventilation as required.
- Carrying out specified operating and combustion checks.
- Completing inspection or cleaning required by the manual.
- Recording findings and the maintenance completed.
See our annual boiler servicing in London page for the broader service scope.
Ask what service record will be supplied and retain it with your boiler paperwork. A service is scheduled maintenance; any fault needing diagnosis, parts or remedial work needs its own assessment and an explanation of the additional scope.

Frequently Asked Questions
Should a Worcester Bosch boiler be serviced every 12 months?
Arrange annual servicing in line with the instructions and manufacturer terms that apply to your boiler. Keep the service record with your appliance paperwork so the maintenance history is available when needed. If a fault develops between services, arrange an assessment rather than waiting for the next scheduled maintenance visit.
How long is the manufacturer warranty on my Worcester Bosch boiler?
The length of manufacturer cover depends on the applicable product and registration terms. Check your registration confirmation and ask Worcester Bosch to confirm the period for your appliance. Have the model and installation paperwork available. Do not assume that another boiler in the same range has identical cover.
Will a missed annual service put my manufacturer warranty at risk?
Missing a required service can put manufacturer cover at risk; the outcome depends on the applicable terms. Keep the records you have and check your individual position with Worcester Bosch. A later service should not be assumed to restore cover, and a missed appointment does not establish the outcome of every claim.
What happens if the engineer finds a fault during the service?
A fault found during servicing needs assessment of its safety implications and any repair required. Ask the engineer to explain the finding, what has been recorded and the proposed remedial work. Confirm the scope and charges before authorising additional work. If the appliance is unsafe, follow the engineer’s safety instructions and do not restart it.
How do I check the engineer is Gas Safe registered?
Check the engineer’s Gas Safe ID and verify that their registration and qualifications cover your boiler work.
- Match the photograph and identity to the person attending.
- Verify that their registration is current.
- Check the listed appliance and work categories.
Our business registration is 648977. Gas Safe registration is separate from manufacturer accreditation.
