Boiler Installation in Colchester.
Need a new boiler in Colchester? KJD Heating Services supplies and installs Worcester Bosch and Vaillant boilers with up to 12-year manufacturer warranties. Gas Safe registered, Checkatrade approved, and owner-led from survey to handover.
A proper boiler install from a qualified local engineer.
A new boiler is a big investment — and a bad install costs you more in repairs, lower efficiency and cold showers. Kieran is a Gas Safe registered engineer (registration can be verified on the Gas Safe Register) and an accredited installer for Worcester Bosch and Vaillant, meaning we can offer manufacturer-backed warranties of up to 12 years that non-accredited installers simply can’t match.
Every Colchester boiler installation we do includes a full system survey, magnetic system filter, inhibitor top-up, condensate pipework and a thorough commissioning certificate.
