We offer a range of combi, system, regular and heat-only boilers from established heating manufacturers. Product availability may vary by brand and output.

The right boiler depends on your property size, number of bathrooms, hot-water demand and existing heating system. A qualified heating engineer should assess your property before purchase or installation.

A combi boiler provides heating and hot water without a separate cylinder. A system boiler works with a hot-water cylinder, while a regular boiler normally uses both a cylinder and a cold-water storage tank.

We can provide general product guidance, but the final boiler type and output should be confirmed by a qualified heating professional who has assessed your property.

Some boilers are sold with a horizontal flue, while others are supplied as boiler-only products. The package contents are clearly stated on each product page.

Compatible vertical flues may be available as separate accessories. Always confirm compatibility with the exact boiler model before ordering.

Yes. Our accessories range may include flues, extensions, filters, thermostats, controls and other installation components.

Review the compatibility information on the product page and compare the boiler model and manufacturer reference. Contact our support team before ordering when you are uncertain.
