Boiler Service Marshalswick

A Proper Boiler Service, From Just Down the Road

Marshalswick is part of St Albans and one of the closest areas to our base on Lemsford Road, so a service here is easy to fit around your day. We service combi, system and regular boilers of all major makes, following the manufacturer’s instructions for each model.

An annual service keeps you safe, keeps the boiler efficient and keeps your warranty valid, because almost every manufacturer requires a yearly service by a Gas Safe engineer, recorded in the boiler’s Benchmark log.

Much of Marshalswick was built in the 1950s and 60s and Jersey Farm in the 1970s and 80s. Many homes still have a system or regular boiler with a cylinder, so we also check the pump, motorised valves and cylinder thermostat, which are often what fails first.

What Your Boiler Service Includes

Every service follows the manufacturer’s instructions for your model. The best time to book is late summer or early autumn, before the heating goes on and before breakdown calls fill the diary. These are the checks your service includes.

Flue Gas Analysis: We test combustion with a calibrated flue gas analyser to confirm the boiler is burning safely and efficiently, and check carbon monoxide levels.
Gas Rate and Pressure: We check the boiler is receiving the right amount of gas at the right pressure.
Flue and Seals: The flue route, joints and terminal inspected, and the case seals checked so fumes cannot escape into the room.
Burner, Electrodes and Heat Exchanger: Inspected and cleaned where the manufacturer requires it, as worn electrodes are a common cause of ignition faults.
Condensate Trap and Pipe: Cleaned and checked, as a blocked or frozen condensate pipe is one of the most common winter breakdowns.
Safety Devices and Pressure: Pressure relief valve, expansion vessel, system pressure and the boiler’s safety devices tested.

Book a Service Soon If You Notice

These are signs your boiler is overdue for a service or needs attention now.

It Has Been Over a Year

Most warranties require an annual service, and a missed year can void cover for later repairs.

A Yellow or Lazy Flame

On boilers with a visible flame, it should be crisp and blue. Yellow or orange flames need checking straight away.

Pressure Keeps Dropping

Having to top up the pressure regularly usually points to a leak or an expansion vessel that needs recharging.

New Noises or Smells

Banging, whistling, gurgling or any unusual smell from the boiler should be checked by an engineer.

 Trustindex verifies that the original source of the review is Google. Really happy with the work carried out by Alban Plumbing and Heating. 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.

 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.

Boiler Service Marshalswick: Your Questions

How often should my boiler be serviced?

Once a year. Almost every manufacturer requires an annual service by a Gas Safe registered engineer for the warranty to remain valid, and a yearly check is the best way to catch faults before they turn into breakdowns.

What does a boiler service include?

A full service includes a flue gas analysis, gas rate and pressure checks, inspection of the flue and seals, cleaning of the condensate trap, checks on the burner and electrodes, and tests of the safety devices, pressure relief valve and expansion vessel. The exact steps follow the manufacturer’s instructions for your model.

How long does a boiler service take?

Usually between 45 minutes and an hour. It can take longer on older boilers, or if the system and cylinder controls are checked at the same time.

When is the best time to book?

Late summer or early autumn. Any faults are found before you need the heating every day, and engineers are easier to book than in the first cold weeks of winter.

Can you service a system or regular boiler with a hot water cylinder?

Yes. On these systems we also check the pump, the motorised valves and the cylinder thermostat, which are common points of failure in older Marshalswick and Jersey Farm homes.

How much does a boiler service cost?

We confirm the price when you book, so you know the cost before we arrive. If the service shows that something needs repairing, we explain it and agree the price with you before doing any extra work.
