Boiler Replacement Advice & Installation Support

Planning a new boiler? EvoHome Improvements helps homeowners think through whether to replace like-for-like, upsize, downsize, switch system type (combi, system or regular), relocate the boiler, or consider lower-carbon alternatives such as a heat pump before requesting quotes. Suitability depends on property size, hot water demand, radiator and pipework condition, flue routing, gas supply and existing controls.

EvoHome Improvements advises and coordinates — independent vetted Gas Safe registered heating engineers carry out the physical installation, commissioning and certification. We do not quote fixed prices, guaranteed running cost savings, guaranteed warranty outcomes or specific timescales without a proper site survey. Boiler replacement remains one of the most impactful home improvements for comfort and energy savings.

Modern condensing boilers achieve 92–94% efficiency compared to 60–80% for older models, potentially saving £200–£400 annually on gas bills.\n\n## When to Replace\n\nBoilers typically last 12–15 years. Key replacement indicators include: frequent breakdowns, rising repair costs, uneven heating, increased energy bills, and parts becoming unavailable.

If your boiler is over 10 years old and requiring annual repairs, replacement is usually more economical than continued maintenance.\n\n## Choosing the Right Boiler\n\nCombi boilers heat water on demand without a cylinder, ideal for 1–3 bedroom homes with one bathroom. System boilers work with a hot water cylinder, providing better flow rates for homes with multiple bathrooms.

Regular (conventional) boilers suit existing gravity-fed systems in older properties.\n\n## The Future of Home Heating\n\nThe UK government plans to phase out new gas boiler installations from 2035 as part of net-zero commitments. While a new gas boiler remains a valid choice today (with a 12–15 year lifespan), homeowners should consider 'hydrogen-ready' boilers where available, or plan for a future transition to heat pump technology.

\n\n## Installation Standards\n\nAll gas boiler installations must be completed by a Gas Safe registered engineer. The installation should include a system flush or powerflush, magnetic filter, and modern controls (room thermostat, programmer, TRVs). Building Regulations notification is handled by the Gas Safe engineer.

\n\n## Hampshire Considerations\n\nMany rural Hampshire properties are off the gas grid, relying on oil or LPG boilers. These homeowners should consider the Boiler Upgrade Scheme grant (£7,500 towards heat pump installation) as an alternative to like-for-like oil boiler replacement.
