Boiler Servicing for AL5

Protecting Your Boiler Warranty

Many newer boilers in Harpenden come with long manufacturer warranties, but almost all of them depend on one thing: a service every year by a Gas Safe registered engineer, with a record kept. Miss it and a later breakdown may not be covered. We service to the manufacturer’s checklist and record the service so you have the evidence if you ever need to make a claim.

For older boilers outside warranty, a yearly service is about reliability. Most breakdowns we are called to in winter start as small problems that would have been spotted during a service, such as a weak expansion vessel, a partly blocked condensate trap or a seal starting to fail.

The best time to book is spring or summer, before the autumn rush. For breakdowns, see our boiler repair service, and for our other local work, the Harpenden plumbing and heating page.

What a Warranty-Standard Service Includes

These are the checks that make a service count for warranty purposes.

Manufacturer Checklist: We follow the boiler maker’s service schedule for your model.
Combustion Test: Flue gas readings recorded to show the boiler is burning correctly.
Component Inspection: Burner, electrodes, seals and heat exchanger inspected and cleaned where needed.
Safety Checks: Gas pressure, flue integrity and safety devices tested.
Service Record: The service is recorded so you have proof for any warranty claim.

Reasons to Book Now

These are good reasons not to put the service off.

Warranty Renewal Due

Most warranties need a service within 12 months of installation and every year after.

Winter Approaching

Engineers are far busier once the cold weather arrives. Booking early is easier.

Pressure Dropping

A slow pressure loss can be spotted and fixed during a service.

Unusual Noises

Banging or whistling are worth checking before they turn into a breakdown.

They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house.
The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work.
I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

The engineer arrived on time, quickly identified the problem, and explained everything clearly before carrying out the work. The job was completed to a high standard, and everything was left clean and tidy afterwards.

What stood out most was their professionalism, reliability, and honest approach. Communication was great throughout, and the pricing was fair with no unexpected surprises.

I would highly recommend Alban Plumbing and Heating Ltd to anyone in St Albans and the surrounding areas looking for a trustworthy plumbing and heating company. I will definitely use them again in the future.

 Trustindex verifies that the original source of the review is Google. Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come.  His 5 star status is well deserved.
