Yes, we do. We're fully qualified to install, service, and repair LPG (liquefied petroleum gas) boilers, which are ideal for properties that aren't connected to the mains gas network. Many homes across rural Sussex rely on LPG, and we regularly carry out installations in these areas. We supply LPG-compatible models from leading manufacturers including Worcester Bosch, Vaillant, and Ideal, all rated A for energy efficiency. Our engineers hold the specific LPG qualifications required on top of their Gas Safe registration, so you can be confident the work is carried out safely and to the highest standard. Whether you're replacing an old LPG boiler or converting from oil, get in touch and we'll talk you through your options.
Not necessarily, but it's worth having it assessed. Most boilers are designed to last 10–15 years with annual servicing. After 15 years, efficiency drops noticeably — older models may only be 60–70% efficient compared to 90%+ for a new A-rated boiler. If yours is still working but costing more to run or needing frequent repairs, replacing it usually makes better financial sense over the medium term. We're happy to provide an honest assessment at no cost.
Switching from an old, inefficient boiler to a modern A-rated model can save a typical Sussex household up to £300–£580 per year on gas bills, depending on the age and condition of the existing boiler. Homes with older G-rated boilers (below 70% efficiency) see the biggest savings. Over the 10–15 year lifespan of a new boiler, those savings can more than cover the cost of the installation.
For most homes in Sussex, a combi boiler is an excellent choice. It heats water directly from the mains on demand, so there's no need for a separate hot water cylinder or cold water tank in the loft — freeing up valuable space. Combi boilers are compact, energy efficient, and ideal for small to medium-sized properties with one or two bathrooms. For larger homes with higher hot water demand, a system boiler with a cylinder may be more suitable. We'll assess your property and usage during your free survey and recommend the best option for your needs.
Warning signs of an unsafe boiler include a yellow or orange flame instead of a crisp blue one, dark staining or scorch marks around the boiler, a pilot light that frequently goes out, unusual smells when the boiler is running, and excessive condensation on windows. If you notice any of these signs, turn the boiler off, open windows for ventilation, and call a Gas Safe registered engineer immediately. Never attempt to inspect or repair a gas appliance yourself. If you suspect a gas leak, call the National Gas Emergency line on 0800 111 999 straight away.
