Frequently Asked Questions
Why should I service my boiler every year?
An annual service keeps your boiler running safely and efficiently. It helps prevent breakdowns, reduces energy usage, and ensures dangerous issues like CO leaks or faulty components are caught early. Most boiler warranties — including Blue Flame’s — also require yearly servicing to remain valid.
What’s included in a full boiler service?
A Blue Flame boiler service includes a complete strip-down (if required) and safety inspection, flue analysis, combustion checks, cleaning of key components, pressure and seal checks, ventilation checks, and an overall performance assessment. You also receive a digital report for your records.
How long does a boiler service take?
Most services take 30–60 minutes, depending on the boiler type, installation, and accessibility. Older boilers or neglected systems may take slightly longer.
How much does a boiler service cost?
Blue Flame offers a fixed-price boiler service with no hidden charges. The price covers all safety checks, cleaning, analysis, and your digital service report.
Can you service all boiler brands and models?
Yes. Our Gas Safe engineers service all major boiler brands, including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, and more. We service combi, system, and heat-only boilers.
Will a boiler service fix problems or faults?
A service focuses on cleaning, checking, and maintaining the boiler. If we identify a fault during the service, we’ll clearly explain the issue and provide repair options and pricing before carrying out any work.
What happens if my boiler fails the safety checks?
If a safety issue is identified, our engineer will explain the problem clearly and advise on the safest solution. In rare cases, the boiler may need to be switched off until the fault is repaired. Your safety always comes first.
Frequently Asked Questions
Will a boiler service keep my warranty valid?
Yes — most manufacturers require annual servicing to maintain your warranty. Blue Flame also requires yearly servicing to keep your Blue Flame Warranty™ active. Your service report can be used as proof of maintenance.
Do you provide a service report or certificate?
Yes. After every boiler service, we issue a digital performance & safety report summarising all checks completed, combustion readings, and any recommendations.
Do you remind me when my next service is due?
Yes — we send automatic annual reminders by text and email so you never miss your servicing deadline or void your warranty.
Can I upgrade to a boiler cover plan after the service?
Absolutely. Once your boiler passes its safety inspection, you can join any of our Boiler Cover Plans, including Silver, Gold, Gold+ or Blue Home.
Do you check carbon monoxide and ventilation during the service?
Yes. CO checks, ventilation assessments, and combustion analysis are a standard part of every boiler service to ensure your home remains safe.
What areas do you cover for boiler servicing?
We cover Cardiff, Caerphilly, Pontypridd, Porth, Pontyclun, Bridgend, Rhondda Cynon Taf, and most surrounding South Wales areas.
Do you offer same-day or urgent boiler services?
Where possible, yes. Availability varies by location and schedule, but we always prioritise vulnerable households and urgent safety visits.
Frequently Asked Questions
Can I book a boiler service online or by phone?
Yes. You can book online in minutes or call our office for help choosing a time that suits you.
However, this function can be in-active during busy spells.
Do you clean the inside of the boiler during the service?
Yes. Depending on the boiler type, our engineers remove the casing and clean or inspect accessible parts such as the, condensate trap, electrodes, bruner and heat exchanger to ensure peak performance.
Should I service my boiler even if it’s working perfectly?
Yes. Most breakdowns occur in boilers that haven’t been serviced. A boiler may work today but be developing hidden issues. Servicing prevents these from becoming expensive faults later.
Can a service reduce my heating bills?
Yes — a clean, well-tuned boiler runs more efficiently and uses less gas, which can reduce your energy costs throughout the year.
What’s the difference between a service and a repair?
A service is preventative maintenance: checks, cleaning, and performance optimisation.
A repair fixes a fault that’s already present.
During a service, we may find an issue and recommend a repair separately.
Can you service older boilers or back boilers?
Yes — we can service most older boilers. Back boilers, floor standing boilers and discontinued models may require specialist parts, but our engineers will advise on safe servicing or upgrading if needed.
Will you clean my Magnetic Filter?
Yes — we will clean your magnetic filter if it is a good-quality unit and in safe working condition at the time of service.
If the filter is old, low-quality, corroded, damaged, or shows signs of weakened seals, we may decline to clean it.
This is to prevent leaks or system damage caused by disturbing a filter that is already compromised.
If you request that we clean the filter against our professional recommendation, the following applies:
-
Blue Flame accepts no liability for any leaks, seal failures, or faults that occur as a result.
-
Any repair, replacement, or remedial work required due to cleaning a compromised filter will be the customer’s responsibility.
-
Our engineer will note this clearly on your service report before proceeding.
This protects both you and your heating system, while ensuring all work is carried out safely and professionally.
