What to consider before booking
A new boiler needs to suit both the home’s heating demand and the way the household uses hot water. A higher output is not automatically better: an oversized appliance may cycle unnecessarily, while an unsuitable hot-water arrangement can leave two bathrooms competing for supply.
Combi, system or regular boiler?
A combi heats domestic hot water on demand and can free up cylinder space. It still depends on the incoming water supply and may not suit simultaneous high-demand outlets. A system boiler with a cylinder stores hot water and can be a better option where several bathrooms are used together. A regular boiler may be appropriate when retaining an existing compatible arrangement. The survey should compare these options before deciding to convert the system.
What should the installation survey cover?
The existing flue route, gas supply, condensate disposal, electrical connections and access all influence the job. Inside the home, radiator performance, water quality and control compatibility matter too. Tell Aura about rooms that remain cold, repeated pressure loss and any planned extension. Replacing the appliance alone will not necessarily correct those problems.
What happens on installation day?
The agreed work should include safe removal of the old appliance, installation of the specified boiler and associated components, commissioning and a practical handover. Ask for the exact cleaning method, filter, controls, disposal arrangements and documentation to be itemised. The time without heating or hot water depends on whether this is a straightforward replacement, a relocation or a system conversion.
Compare the whole quotation
A cheaper headline can exclude a control upgrade, access equipment or changes to the flue. Compare the model, labour, system work, VAT treatment and warranty conditions on the same basis. Confirm who registers the warranty and what servicing is needed to maintain it. No warranty length is promised until the proposed model and terms are confirmed.

Enquire about boiler installation & replacementYour questions answered
Can you move my boiler to another room?
A relocation may be possible after checking the flue, gas supply, condensate drainage and access. It usually involves more work than replacing a boiler in the same position.
Do I need a new boiler if mine is old?
Age alone is not a diagnosis. Condition, repair history, parts availability and your future heating plans should inform the decision.
Will a bigger combi improve my shower?
Only if the incoming water supply and the complete hot-water arrangement can support the required flow. Boiler output alone cannot solve a restricted supply.
