Registration, commissioning records and annual servicing commonly matter, while external system problems or contamination may be excluded. Check your written terms and contact the manufacturer before arranging work on an appliance under cover.
A boiler warranty can provide reassurance after a new installation, but the number of years is only part of the story. Derby homeowners also need to understand registration, servicing, exclusions and who to contact if a fault develops.
Etta Plumbing & Heating Services has served Derby since 1997. This guide explains what to check in the manufacturer’s terms and how to keep useful records, without assuming every brand or model offers the same protection.
- Read the specific model and offer terms before comparing warranty lengths.
- Annual servicing is commonly a condition of continued cover.
- Registration and commissioning records matter.
- A boiler warranty does not automatically cover the whole heating system.
- Ask the manufacturer about missed requirements rather than assuming the outcome.
Boiler warranty: start with the actual terms
Warranty and guarantee language differs between manufacturers, so the title alone does not tell you the scope of protection. Read the terms for the chosen product, installation date and offer, and retain a copy with the invoice.
For a Derby homeowner, useful questions include which components are covered, whether labour is included and who authorises repairs. A long period is less useful if the circumstances of your installation do not qualify for it.
Our boiler replacement assessment includes discussion of the proposed appliance. Etta offers new boilers with up to 12 years of manufacturer warranty, but the exact duration and conditions depend on the qualifying product and installation.
Boiler warranty and registration after installation
Manufacturers commonly require the appliance to be registered within their stated arrangements. Check that registration has been completed, that the address and installation date are correct and that you have confirmation of the recorded cover.
In Derby homes, do not assume the boiler's warranty is active simply because the box was opened by an installer. Ask for the registration details and the commissioning record, and keep them somewhere accessible.
If information is missing, contact the installer and manufacturer promptly. Requirements and remedies vary, so it is better to establish the position early than discover a problem when the boiler needs attention years later.
Annual servicing is usually part of keeping cover
A manufacturer may require a service every year in accordance with its instructions, together with evidence of completion. This is separate from the warranty repair service, and routine maintenance is not necessarily included in the warranty price.
Derby homeowners should record the service date, engineer details and relevant documentation. Our boiler servicing service can help maintain the appliance, but the engineer needs to follow the requirements for the specific model.
Check the applicable timing rules rather than assuming an unlimited grace period. If a service is overdue, book it and ask the manufacturer about the impact on cover; a later service should not be described as automatically restoring every entitlement.
What boiler cover commonly includes and excludes
Manufacturer protection commonly relates to faults in the boiler within the scope of its terms. External controls, pipework, radiators, the incoming supply and other parts of the heating system may have separate arrangements or be excluded.
For example, Worcester Bosch's published boiler terms distinguish covered product defects from various external causes and routine servicing. Do not apply those conditions to a different manufacturer without checking its own wording.
In a Derby home, a boiler fault and a cold radiator may therefore lead to different repair routes. Ask what the diagnosis is, which product is affected and whether the proposed visit is a warranty attendance or chargeable system work.

Poor system water quality can affect components, and manufacturers may exclude damage caused by sludge, scale or blockages. The cleaning and treatment requirements should be considered during installation rather than left for the first fault.
Etta includes a central heating power flush with every boiler installation. Our power flushing page explains the service, but installation records should still identify the work completed and any relevant treatment.
For Derby homeowners, protecting the appliance also means addressing leaks and repeated pressure loss promptly. The precise warranty position depends on the terms and findings, so avoid assuming a filter alone guarantees acceptance of any future claim.
Gas or carbon monoxide emergency: if you smell gas, a carbon monoxide alarm sounds or you suspect exposure, leave the property and call 0800 111 999 from outside. Avoid naked flames and electrical switches; ventilate and turn off gas at the meter only if safe. Seek urgent medical help for symptoms, and call 999 for severe symptoms or immediate danger. For LPG, contact your supplier. Do not reuse the appliance until a suitably qualified engineer has checked it.
Repairs, modifications and access can affect claims
Before arranging an independent repair to a boiler under cover, contact the manufacturer or check its stated process. Some terms require authorised attendance, and an unapproved intervention can complicate the assessment.
Do not remove the casing, modify controls internally or attempt gas work yourself. In Derby, use an engineer qualified for the fuel and appliance, and tell them about the active manufacturer cover before work is agreed.
Also preserve practical access to the boiler. Boxing it in during kitchen work can make a repair difficult, so plumbing alterations and cabinetry should account for the appliance's installation and maintenance requirements.
Moving home, transferring cover and changing details
Some manufacturers allow protection to continue for a new owner, subject to the relevant conditions, while others require specific notifications. Read the terms and confirm the address, ownership details and service records before assuming cover has transferred.
When selling a Derby property, a clear file helps the next owner understand the boiler's installation and maintenance history. Warranty confirmation, service records and operating instructions are useful documents to provide through the normal sale process.
If you buy a home and cannot find the paperwork, ask the manufacturer to check the product details. A label or remembered installation date alone may not establish the length or validity of cover.
Warranty, workmanship and insurance are separate
Manufacturer cover, an installer's workmanship commitment and a paid maintenance plan deal with different responsibilities. Paying for an additional plan does not necessarily extend the manufacturer’s warranty, and duplicated cover should be checked carefully.
Our Derby installation work is guaranteed: if something is not right with our workmanship, we put it right. That commitment should not be confused with a promise that every external component or future fault is included indefinitely.
Ask for an explanation of which organisation handles each type of issue. The Etta price list identifies normal service and fault-finding charges separately from installation quotations, helping you distinguish routine work from qualifying manufacturer repairs.
How to deal with a fault while cover is active
Record the model, serial number, fault code and symptoms without dismantling the appliance. Have the installation date, warranty confirmation and service history ready when contacting the manufacturer or our Derby team.
Ask whether the attendance is covered and what could make it chargeable. An external supply issue or a problem outside the product's scope may be treated differently from a covered component defect.
If a claim is declined, request the reason and the term relied upon, then follow the manufacturer’s review process where appropriate. Keep the exchange and engineer findings; this is more useful than relying on a broad statement that the whole warranty has been “voided”.

Speak to our teamFAQs: boiler warranty in Derby
Does every new boiler have a 12-year warranty?
No. Etta offers up to 12 years on qualifying installations, but the model and offer conditions determine the actual period. Check the written confirmation for your boiler.
Is the annual service included in the warranty?
Not necessarily. Manufacturer warranties commonly require servicing without paying for that routine work, so check the specific terms.
Will one missed service automatically void everything?
Do not assume the outcome. Arrange the overdue service and ask the manufacturer how its terms apply to your particular boiler and circumstances.
Does warranty cover cold radiators?
Not automatically. A radiator, valve or external system fault may fall outside the boiler product cover and need a separate assessment.
Who should I contact before a warranty repair?
Use the manufacturer’s stated claim process or ask the installer for guidance. Check authorisation and possible charges before arranging independent work.
