Electrical Supply & Earthing
Check the electrical supply and earthing arrangements to the boiler, helping identify visible or testable issues that could affect safe appliance operation.

Casing Seals & Combustion Chamber

More Than Just a Visual Inspection
A proper gas boiler service involves checking the appliance's safety, condition and operation using the relevant manufacturer's servicing instructions.

Why Is Annual Boiler Servicing Important?
Your boiler works hard throughout the year to provide heating and hot water. Regular servicing helps maintain safe operation, identify developing issues and support reliable performance when you need it most.
Service Your Boiler Every 12 Months
Most boiler manufacturers recommend servicing at least once a year. An annual appointment helps ensure your boiler receives the checks and maintenance specified for its model.
Help Maintain Gas Safety
Boiler servicing includes important safety checks covering combustion, flue arrangements, gas supply and appliance operation. These can help identify conditions that may present a safety risk.
Support Boiler Efficiency
Checking combustion performance, operating conditions and relevant components can help identify issues that may affect your boiler's efficiency and performance.
Reduce the Risk of Breakdowns
Routine inspections can reveal signs of wear, deterioration or developing faults before they become more disruptive, helping reduce the likelihood of unexpected problems.
Help Protect Manufacturer Warranties
Many boiler warranties require regular servicing by a suitably qualified engineer. Keeping your service records may help demonstrate that the manufacturer's maintenance conditions have been followed.
Support a Longer Boiler Lifespan
Regular maintenance helps keep important components checked and can identify issues that may contribute to premature wear, supporting the long-term care of your heating appliance.
Peace of Mind for Your Property
Whether you own your home or manage a rental property, regular servicing provides an opportunity to have your boiler professionally checked and receive advice on its condition.

Types & Brands of Boilers We Service

Gas Boilers We Can Service
Different boiler systems have different servicing requirements. Our engineers follow the relevant manufacturer's instructions for each appliance.
Combi Boiler Servicing
Combination boilers provide central heating and hot water directly from one appliance, without requiring a separate hot water storage cylinder.
System Boiler Servicing
System boilers are typically connected to a separate hot water cylinder and are often installed in properties with greater hot water demand.
Regular & Conventional Boilers
Also known as heat-only boilers, these appliances commonly form part of traditional heating systems with separate hot water storage and associated system components.
Boiler Brands We Work With
Our engineers are familiar with many widely installed domestic gas boiler manufacturers. Servicing procedures depend on the appliance model and manufacturer's requirements.

Boiler Service vs Gas Safety Certificate
These are two different services, even when arranged during the same appointment.
Boiler Servicing
Focuses on maintenance, condition, operation and manufacturer-specific servicing procedures. It helps identify developing faults and maintain the appliance.
Gas Safety Certificate (CP12)
Records the findings of a gas safety inspection. For rental properties, landlords must arrange the required checks on relevant gas appliances and flues at least every 12 months.
Our £99 Boiler Service Package: Includes a complimentary Gas Safety Certificate following the applicable safety checks. If your property has additional gas appliances, please tell us when booking so the correct inspection scope can be arranged.
Annual Gas Safety Checks Are a Legal Requirement
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must arrange annual gas safety checks for relevant gas appliances and flues by a Gas Safe registered engineer, maintain gas equipment in a safe condition and provide tenants with the required gas safety records. A routine boiler service alone does not replace these legal checks.

For homeowners, an annual boiler service is generally recommended rather than legally required, although it may be necessary to maintain a manufacturer's warranty.
Landlords have legal duties to maintain gas appliances and flues safely and arrange annual gas safety checks for relevant appliances. A routine service alone does not replace those checks.

Regular servicing can help identify signs of wear, deterioration or developing faults before they lead to more serious problems. However, no service can guarantee that a boiler will not break down in the future.

Many manufacturers require annual servicing by a suitably qualified engineer as part of their warranty conditions. The exact requirements vary by manufacturer and model, so you should check your warranty terms and retain your service documentation.

The engineer will explain the findings and advise on the appropriate next steps. If a fault requires investigation or repair, this is normally arranged separately from routine servicing.
Where an unsafe condition is identified, the engineer will follow the applicable gas safety procedures.

Magnetic filter cleaning is available as an optional addition to our standard boiler service for £35. The filter must be accessible and suitable for cleaning.

12 What should I do before my boiler service appointment?
Please ensure the engineer can access the boiler and that the gas and electrical supplies are available. Let us know about any existing faults or unusual symptoms before the appointment.
