Is Main still its own boiler brand?

Not as it used to be, as it now sits within Baxi. Your Main boiler can still be repaired and serviced, and many of its parts come from the Baxi group. When it comes to replacing it, we would judge today’s range on its merits instead of assuming the same badge.

My Main is old but works. Do I need to replace it now?

Not purely because of its age. If it is safe, serviced and not running up repair bills, keeping it going is reasonable. Plan the replacement once repairs start to mount up, ideally in the warmer months.

Why is my Main rumbling like a kettle?

Most often, water is boiling in pockets inside the heat exchanger because limescale or sludge has narrowed the flow. It is common on older boilers in hard-water London and should be looked at, not ignored.

Can you repair and service my Main Heating boiler?

Yes. Our gas work is done by Gas Safe registered engineers, as the law requires for any gas boiler, whatever the make.

The make

Main Heating boilers

Main used to be a popular value make, and its products are now part of Baxi instead of a separate line. In practice that matters. Plenty of Main boilers are still working in London, but it would be wrong to describe Main as a separate range on sale today. Ninja Plumbers repairs, services and replaces them, and would take you through the current Baxi-group choices rather than pretend a like-for-like new Main is still made.

The Main Heating range

Main was a value brand, fitted widely by installers and landlords who wanted a dependable boiler at a low price. Its products now sit within Baxi, part of BDR Thermea. For an owner, "transitioning" means your Main is still an ordinary gas boiler that any Gas Safe engineer can service and repair, often with Baxi-group parts. It does not mean you can order a like-for-like new Main.

Main Heating is now part of a bigger group instead of a fully separate range on sale today. We repair, service and replace these boilers.

Faults we often find on Main Heating boilers

Many budget-fitted boilers now getting old
Repairs using parts that come from the Baxi group
Replacing boilers that were a minimum-spec choice first time
Vessels and valves worn out by years without a service
Combis too small for a home that has grown since

This list reflects what Ninja Plumbers finds across Main Heating boilers in general. It is not a diagnosis of yours, and we confirm any fault on site before giving a price.

Main Heating servicing

Most Main boilers are old enough that any warranty has run out; if yours is newer, the warranty will usually hinge on annual servicing, so check your warranty terms. The engineer looks for the signs of age these budget-fitted boilers tend to show: tired expansion vessels, weeping valves and condensate pipes never protected from frost.

Repair it or replace it?

Where the failed part is a Baxi-group component that can be sourced, a repair on a sound Main is usually worth it. Where a major part fails on a boiler past twelve years, or the part cannot be found, replace it. If your Main was a minimum-size combi in a flat that has since gained a bathroom or loft room, a properly sized replacement fixes a problem you may have lived with for years.
