Need A Boiler Service?
Book your annual boiler service with our Gas Safe engineers. We cover St Albans, Harpenden, Hatfield, Watford, Welwyn Garden City, Redbourn and London Colney.
Annual gas boiler servicing across St Albans and Hertfordshire by Gas Safe registered engineers. We check your boiler is safe, clean and working efficiently, so you are far less likely to be caught out by a breakdown when the weather turns cold.
Most boiler breakdowns we are called to in the middle of winter could have been picked up months earlier. A blocked condensate trap, a worn seal, a fan starting to fail or an expansion vessel that has lost its charge will often show clear signs at a routine service, long before the boiler stops working altogether.
Our engineers service combi, system and regular gas boilers from all the major manufacturers, and we are accredited installers for Vaillant, Ideal, Baxi and Worcester Bosch. Every service follows the manufacturer’s checklist for your model, includes a flue gas analysis, and ends with a written service record for your paperwork.
If the service shows your boiler needs attention, we explain what we found and give you a clear price before any extra work. For a boiler that has already broken down, see our boiler repair service. If your boiler is near the end of its life, our boiler installation team can give you a fixed quote for a replacement.
Sludge and limescale are common in St Albans heating systems because of the hard water. Where we see cold spots on radiators or a noisy boiler, we may recommend a powerflush or a magnetic system filter as part of our wider water treatment options.
A boiler service is a detailed safety and performance check carried out by a Gas Safe registered engineer. It is different from a quick visual check: the engineer opens the boiler, inspects and cleans the key parts, and tests that it is burning gas safely and efficiently. Most manufacturers require one every 12 months to keep the warranty valid.
If it has been more than a year since your boiler was last serviced, it is due. These signs mean it is worth booking sooner rather than later.
A healthy gas flame burns blue. A lazy yellow or orange flame can point to poor combustion and should be checked straight away.
If you keep topping up the boiler pressure, there may be a leak or a problem with the expansion vessel that a service will pick up.
Banging, gurgling or whistling, or any unusual smell near the boiler, are signs it is not running as it should.
A boiler that is not burning efficiently uses more gas to produce the same heat. A service helps it run as efficiently as possible.
From a standard annual service to landlord gas safety checks and system protection, we look after your boiler and heating system so it keeps running safely all year.
Call or send a quick message and we will book a time that suits you, with reminders each year if you want them.

Once every 12 months. Most manufacturers require an annual service by a Gas Safe registered engineer to keep the warranty valid, and it is the best way to catch small faults before they turn into a breakdown.
Usually between 45 minutes and an hour and a half, depending on the boiler model and whether any parts need cleaning or adjusting.
Visual and safety checks, removing the case to inspect and clean the burner, heat exchanger, electrodes and condensate trap, gas pressure and rate tests, a flue gas analysis, and checks on system pressure, controls and safety devices. You receive a written service record.
Not quite. A gas safety check confirms appliances are safe to use, while a service also cleans and tunes the boiler for reliable, efficient running. Landlords need a gas safety check every year, and we can do both in one visit.
Late summer or early autumn, before the heating goes on full time. Any issues can then be fixed before the cold weather arrives and engineers are busiest.
