Worcester boiler 4000 25kw (7 years warranty)
Had a Worcester 4000 25kw (7 years warranty) boiler fitted at my dad house and has been an outstanding upgrade for his home. The build quality feels premium, the system runs quietly, and the heating performance is consistently strong. What stands out most is the efficiency — it warms the house quickly while keeping energy usage impressively low, which is a real win for both comfort and running costs.
The controls are intuitive, making it easy to adjust temperatures or switch modes without any hassle. Even during the colder months, the boiler delivers steady heat and hot water without fluctuation. It’s clear the engineering behind it is top‑tier.
Overall, Worcester Bosch delivers exactly what you want from a boiler: reliability, efficiency, and peace of mind. It’s a brand I’d confidently recommend to anyone looking for a long‑lasting, dependable heating solution.

As part of our ongoing boiler service plan, Company contacted us for our annual service. Kept informed of engineer expected time of arrival by text and phone. Engineer, James Reference S6JM was professional, knowledgeable and worked in a really tidy manner. As boiler is in a wardrobe on grand children’s bedroom, crucial that it’s safe. James advised us on siting the CO detector/ monitor in the safest most efficient place. He also advised us on more economic use of the boiler. James went above and beyond the norm thus delivering a five star customer experience! Thank you.

I had the boiler installed nearly 2 years ago now and it has been brilliant. I have had it set for 'on' all the time during the winter and it kept the house warm without coming on too often. I would recommend the boiler to anyone. it is very reliable.
