💷 How Much Can You Save with a New Boiler?

Swapping an old G-rated boiler for a new A-rated condensing model can save you up to £580 per year (according to the Energy Saving Trust, based on a detached home).

Other long-term benefits include:

Lower gas bills due to higher efficiency (90%+ vs 60–70% on older models)
Fewer repairs and breakdowns = less ongoing cost

Reduced carbon footprint, helping your home meet new eco standards

Over a 10–15 year lifespan, your new boiler could pay for itself through energy savings and reduced maintenance alone.
