Keep your heating safe, efficient and reliable. We service all major boiler brands and provide a written boiler service record after every visit.

A service is preventative maintenance, not a repair. If we find a fault, we explain the options and confirm any additional work and costs before proceeding.

If you have no heating or hot water, or you smell gas, that is an emergency rather than a service issue. See Emergency Boiler Repairs or call us immediately.

What is a boiler service

A boiler service is a routine check carried out by a qualified engineer to confirm your boiler is operating safely and efficiently. It is preventative maintenance, not a repair. The aim is to catch early signs of wear, check safety-critical components, and keep your boiler running reliably.

Boiler servicing is relevant for homeowners, landlords, and tenants with permission from their landlord. Many boiler manufacturers recommend annual servicing to maintain warranty cover, so check your boiler documentation for specific guidance.

Service vs repair: A service is scheduled maintenance. A repair is fault-driven work to fix a problem. If we find a fault during a service, we explain options and quote before any repair work begins.

What’s included in our boiler service

Our Gas Safe registered engineers carry out a thorough inspection covering safety, performance and efficiency. A typical service includes:

  • Visual inspection of boiler casing, controls and flue terminal
  • Safety checks on combustion-related components as applicable to your boiler type
  • Flue gas analysis to check combustion efficiency where appropriate
  • Check boiler pressure and expansion vessel function where accessible
  • Inspect seals, gaskets and heat exchanger for signs of wear or leaks
  • Check for corrosion, leaks and water damage around the boiler
  • Test controls, thermostat response and boiler settings
  • Check radiator and heating system performance basics
  • Clean components where needed and accessible
  • Inspect and clean the condensate trap where accessible
  • Check magnetic filter condition if fitted and advise on cleaning
  • Record findings and advise on any recommended next steps

How long does a boiler service take

A standard boiler service typically takes 30 to 60 minutes, depending on boiler type, age and condition. Older boilers or those with access restrictions may take longer. The engineer will confirm expected duration on arrival.

Time is needed to remove casing, carry out visual and functional checks, complete gas analysis where required, and document findings. If faults are found during the service, the engineer will discuss these separately.

When should you service your boiler

Most manufacturers recommend an annual boiler service to maintain safe operation and protect warranty cover. Check your boiler documentation for specific guidance on service intervals.

Best time to book: Late summer or early autumn is ideal, before cold weather increases demand. Booking ahead helps avoid delays during peak winter months when engineers are busiest with breakdowns.
  • If your boiler has not been serviced in over 12 months, book a service soon
  • If you have recently moved into a property with no service history, book a service soon
  • Landlords often book ahead of winter to reduce breakdown risk and keep maintenance records up to date

Boiler servicing FAQs

How much is a boiler service in London?

Cost depends on your boiler type, its condition and how long it has been since the last service. Tell us the make, model and your postcode when you call and we will confirm a price before booking.

What does a boiler service include?

A visual inspection of the casing, controls and flue, safety checks on combustion-related components, flue gas analysis where appropriate, pressure and expansion vessel checks, inspection of seals and the heat exchanger, control testing, cleaning where accessible, and a written record of the findings.

Is a boiler service the same as a repair?

No. A service is scheduled preventative maintenance. A repair is fault-driven work to fix a specific problem. If we find a fault during a service we explain the options and quote before any repair begins.

How often should a boiler be serviced?

Most manufacturers recommend annually, and annual servicing is often a condition of keeping warranty cover. Check your boiler documentation for the specific interval.

How long does a boiler service take?

Typically 30 to 60 minutes, depending on boiler type, age and condition. Older boilers or restricted access can take longer.

Can you service any boiler brand?

We service all major brands including Worcester, Vaillant, Ideal, Baxi and Glow-worm, plus Viessmann, Potterton, Alpha, Ferroli, Vokera and others. Tell us the make and model when you call.

Do you service landlord and rental properties?

Yes. We service rental properties across London and can also carry out landlord gas safety checks at the same visit.

Do I need a service if the boiler seems fine?

A service is preventative. It catches wear before it becomes a breakdown, keeps the boiler running efficiently, and is often required to maintain manufacturer warranty cover. A boiler that seems fine is exactly the one worth keeping that way.
