TWO WAYS WE HELP
New Boiler Installation or Boiler Replacement
Whether you are installing a boiler where one does not currently exist or replacing an older boiler, we assess the property and existing heating system before recommending the appropriate solution.
New Boiler Installation
For new heating installations or properties requiring a new boiler, we assess the heating and hot-water requirements, boiler position, flue arrangement, condensate requirements and associated pipework before carrying out the installation.
Boiler Replacement
If an existing boiler is old, unreliable, repeatedly breaking down or no longer suitable for the property, replacement may be worth considering. We remove the existing unit where applicable and install a suitable replacement following the required safety and commissioning procedures.
BOILER TYPES
Combi, System or Regular Boiler — Which Is Right for Your Home?
Different homes have different heating and hot-water requirements. We consider the property, existing system, available space and household demand before recommending a suitable boiler type.
Combi Boilers
Combi boilers heat water directly from the mains without requiring a separate hot-water cylinder. They can be a practical option for many smaller and medium-sized homes where space is limited.
System Boilers
System boilers work with a separate hot-water cylinder while incorporating many system components within the boiler itself. They can suit homes with greater hot-water demand.
Regular Boilers
Regular or conventional boilers use a hot-water cylinder and cold-water storage arrangement. They can be appropriate when replacing an existing conventional system or where the property has particular heating requirements.
We install boilers from established manufacturers, including Worcester Bosch, Vaillant, Baxi and Ideal. The appropriate make and model depends on the property and system requirements rather than a one-size-fits-all recommendation.
BOILER REPLACEMENT
When Is It Worth Considering a Boiler Replacement?
Repeated breakdowns
If an older boiler is repeatedly developing faults, replacement may be worth comparing with the cost and reliability of continuing repairs.
An ageing boiler
Older boilers may no longer provide the performance, controls or efficiency available from modern heating systems.
Heating performance
Persistent heating or hot-water problems can be a reason to have the boiler and wider system assessed before deciding what work is appropriate.
Changing household needs
A property with changed occupancy, additional bathrooms or altered hot-water demand may benefit from a reassessment of the boiler system.
Controls and heating upgrades
A boiler replacement can also be an opportunity to review heating controls and other parts of the system where appropriate.
Professional assessment first
Replacement is not automatically the answer. We assess the system and explain the available options before agreed work begins.
THE PROCESS
What Happens During Your Boiler Installation?
Survey and assessment
We assess your existing heating system, property, boiler position, heating and hot-water requirements and any relevant pipework before recommending the appropriate installation.
Quotation and planning
We explain the proposed work and provide clear pricing, with a written quotation for larger installation projects before the agreed work begins.
Preparation and removal
For replacements, the existing boiler is safely disconnected and removed where applicable, with the installation prepared for the new system.
Boiler installation
The new boiler is installed and connected to the heating and hot-water system, including the relevant flue, condensate and associated connections.
Commissioning and safety checks
The installation is commissioned and checked before the system is handed over.
Handover and documentation
We explain the new system and controls, and deal with the relevant manufacturer registration and completion documentation applicable to the installation.
