Boiler Installation FAQs
How long does a new boiler installation take?
Most combi boiler replacements are completed in one day. System changes or oil-to-gas conversions may take longer. We confirm the timeline during your free survey.
How do I choose the right size boiler for my home?
We survey your property, count radiators, assess hot water demand and existing pipework before recommending an appropriately sized boiler — avoiding oversizing or underperformance.
Can you replace a back boiler with a combi in Newbury?
Yes. We regularly convert back boilers and system boilers to modern combis or system setups, upgrading pipework and controls where required.
Should I repair or replace my boiler?
If a boiler is unreliable, uneconomical to repair or nearing the end of its lifespan, replacing it is often the better long-term investment. APS always gives honest advice based on the condition of the appliance — we will not recommend a boiler replacement unnecessarily when a repair is the sensible option.
