Our Seamless Delivery & On-Site Protocol
We understand that having work done in your home requires trust and minimal disruption. Our delivery and installation protocol is designed to be as efficient, respectful, and transparent as possible. We coordinate the delivery of your new boiler and all necessary components to coincide perfectly with the arrival of our installation team, preventing any unnecessary waiting or storage issues on your property. For most standard installations, we can offer a confirmed date within 7-10 days of your signed agreement, with emergency installations often accommodated much faster.
On installation day, our engineers will arrive within a pre-agreed time window. They begin by introducing themselves and walking you through the planned work for the day. We take great care to protect your home, laying down dust sheets, floor protectors, and covering nearby furniture. Our team works cleanly and methodically, ensuring all debris and your old boiler are removed from the site at the end of the job. We believe that professionalism extends beyond the technical work to the respect we show for you and your space. Communication is key; our lead engineer will keep you updated on progress throughout the day and will be available to answer any questions that arise.
Comparing Boiler Technologies
Understanding the right boiler type for your home is the first step. Here's a quick comparison.
Combi Boilers
A single, compact unit provides both central heating and instantaneous hot water. Best for homes where space is limited and hot water demand is not excessively high simultaneously.
- Pros: Space-saving, cost-effective, high efficiency, hot water on demand.
- Cons: May struggle with multiple hot water outlets at once, not ideal for homes with weak mains water pressure.
System Boilers
Requires a hot water storage cylinder, but most other components are built-in. Excellent for homes with multiple bathrooms and a high demand for hot water.
- Pros: Can supply multiple taps simultaneously, fast and efficient, no need for a loft tank.
- Cons: Requires space for a cylinder, hot water is not "instant" and can run out.
Conventional Boilers
The traditional setup with a boiler, cylinder, and cold/hot water tanks. Best for larger homes with older radiator systems that can't handle high water pressure.
- Pros: Ideal for low mains pressure areas, can supply large volumes of hot water, compatible with older systems.
- Cons: Takes up the most space (loft and airing cupboard), more complex installation.
