Annual Boiler Service From £75 + VAT Typical Duration: 40–60 Minutes

Let’s Heat provides annual boiler servicing across Cardiff and selected CF postcode areas, with gas boiler servicing carried out by Gas Safe registered engineers.

An annual service is suitable when your boiler is working normally and is due for routine maintenance. If your boiler has stopped working, is leaking, repeatedly losing pressure or showing a fault code, a boiler repair may be the more appropriate service.

Our annual boiler service is available from £75 + VAT, subject to your boiler, property, postcode and current appointment availability. A routine annual boiler service typically takes around 40–60 minutes, depending on the type and age of the boiler.

When booking, provide your Cardiff postcode, boiler make and model and, if known, the date of its last service.

Annual Boiler Service in Cardiff: Why It Matters

A boiler works throughout the year to provide heating and hot water, but routine maintenance can easily be overlooked while the appliance appears to be working normally.

For Cardiff homeowners, an annual boiler service provides an opportunity for an appropriately qualified engineer to inspect the boiler, carry out the relevant servicing and safety checks and identify visible signs of deterioration or developing problems.

Regular servicing can also be important where the boiler is covered by a manufacturer warranty or guarantee. Many manufacturers require servicing at specified intervals, so check the conditions that apply to your particular boiler.

Service vs Repair Appointments

A boiler service should not be confused with a repair appointment.

If your boiler is operating normally and is due for routine maintenance, book a service. If you already have no heating or hot water, a leak, repeated pressure loss, a fault code or another active problem, our Boiler Repair in Cardiff service may be more appropriate.

You can also learn more about our boiler servicing service and what to expect from routine boiler maintenance.

What Is Checked During a Boiler Service?

The exact servicing procedure depends on the boiler and the manufacturer's requirements, but a boiler service generally involves checking the condition and operation of the appliance and carrying out the appropriate maintenance and safety checks.

Boiler Condition and Controls

The engineer can inspect the general condition of the boiler and check that its controls are operating appropriately.

Visible signs of deterioration, corrosion or leakage can also be identified during the service.

Flue and Relevant Safety Checks

For a gas boiler, appropriate checks relating to the appliance, flue and combustion requirements are carried out as required for the boiler and installation.

Gas boiler servicing should be carried out by an appropriately qualified Gas Safe registered engineer. Let’s Heat’s Gas Safe registration number is 977042, and registration details can be checked through the official Gas Safe Register.

Service Record

Where appropriate, the service record or relevant servicing documentation can be updated after the work has been completed.

Keep your boiler servicing records, particularly if your manufacturer warranty or guarantee requires evidence of regular servicing.

For independent information about boiler maintenance and annual servicing, you can read the Energy Saving Trust guide to boiler servicing.

When Should You Book a Boiler Service in Cardiff?

For most households, annual boiler servicing is a sensible routine. If your boiler manufacturer requires an annual service to maintain its warranty or guarantee, check the terms so that the service is completed within the required period.

Routine Annual Maintenance

You do not have to wait until the boiler develops a problem before arranging maintenance. A service is intended for a boiler that is generally operating normally.

It can also be useful to arrange your service before periods when you expect to rely heavily on the heating, rather than waiting until the boiler develops a fault.

New Property or Unknown Service History

If you have recently moved into a Cardiff property and do not know when the boiler was last serviced, arranging a service can help establish its current condition and give you a new maintenance record going forward.

If you are unsure when your boiler was last serviced, provide the make and model when booking and explain that the previous service history is unknown.

What Happens If the Engineer Finds a Fault?

A boiler service and a boiler repair are different services. During servicing, the engineer may identify a component, leak, deterioration or other issue that requires additional investigation or repair.

Where additional repair work or replacement parts are required, these are separate from the cost of the routine boiler service. You should be told what has been identified and what further work may be appropriate before additional chargeable repair work proceeds.

If your boiler already has an active fault — such as no heating, no hot water, repeated lockouts, a leak or persistent pressure loss — you should normally arrange Boiler Repair in Cardiff rather than booking routine servicing and expecting the service to resolve the fault.

For an older boiler where repairs are becoming frequent or uneconomical, you can also explore Boiler Installation in Cardiff if replacement is being considered.

How Much Does a Boiler Service Cost in Cardiff?

An annual boiler service with Let’s Heat is currently available from £75 + VAT.

The base service price applies where the boiler requires its routine annual service. If replacement parts, additional repair work or further investigation are required, these are charged separately.

The final cost can therefore depend on whether the boiler only requires its planned service or whether a separate fault is identified.

A routine annual boiler service typically takes around 40–60 minutes, depending on the type and age of the boiler. Before booking, check the current service price and what is included in the appointment.

Frequently Asked Questions

How much does a boiler service cost in Cardiff?

An annual boiler service with Let’s Heat is available from £75 + VAT. If replacement parts, additional repair work or further investigation are required, these are charged separately.

How often should I have my boiler serviced in Cardiff?

An annual boiler service is generally recommended for a domestic gas boiler. Regular servicing also helps you follow manufacturer maintenance requirements where annual servicing is a condition of the applicable warranty or guarantee.

When should I arrange the first service for a new boiler?

Check the servicing requirements provided with your new boiler and the conditions of its manufacturer warranty or guarantee. Where annual servicing is required, make sure the first service is completed within the specified period.

Does an annual boiler service keep my warranty valid?

Many boiler manufacturers require servicing at specified intervals as part of their warranty or guarantee conditions. The exact requirements depend on the manufacturer and boiler, so check the terms that apply to your appliance and keep your service records.

What is included in a boiler service?

The exact procedure depends on the boiler and manufacturer requirements. A routine service generally includes checks of the boiler's condition and operation, controls and relevant safety requirements, together with appropriate flue and combustion checks for a gas boiler.

Where appropriate, the boiler's service record or relevant servicing documentation can also be updated.

Do they check radiators during a boiler service?

A standard boiler service is primarily focused on the boiler and the relevant appliance, control and safety checks. It should not be assumed to include a full inspection or repair of every radiator in the property.

If you have a specific problem with a radiator or the wider heating system, mention it when booking so the team can advise whether additional investigation or work may be required.

What are the signs that my boiler may need attention?

If your boiler is simply due for its routine annual maintenance, you can arrange a boiler service even when it appears to be operating normally.

However, problems such as repeated pressure loss, leaks, fault codes, lockouts, unusual operation or loss of heating or hot water can indicate an active fault. In those circumstances, a boiler repair or fault diagnosis may be more appropriate than routine servicing.

Should I keep my boiler service records?

Yes. Keeping a record of completed boiler services can provide useful maintenance history and may also be important where evidence of servicing is required under a manufacturer warranty or guarantee.

Is a boiler service the same as a Landlord Gas Safety Check?

No. A routine boiler service and a landlord gas safety check serve different purposes. Landlords should make sure they meet their legal gas-safety responsibilities separately rather than assuming that a standard boiler service automatically fulfils every landlord requirement.

Should I book a service if my boiler keeps losing pressure?

Repeated pressure loss can indicate a fault rather than a routine maintenance requirement.

If your boiler continually loses pressure, is leaking, locks out or stops providing heating or hot water, arrange fault diagnosis through our Boiler Repair in Cardiff service rather than relying on a routine annual service to resolve the problem.
