 Trustindex verifies that the original source of the review is Google. Booked up annual service and replacement part for my 13 year old Gas boiler from Here 4 Heat. Kian was the engineer who came out to do the job  and was very promted on his timing . . He was very efficient in explaining what was going on and regarding the old part he replaced showed me how it was worn down and needed replacing. Nice to see a young man with good communication skills and having the time to explain. Katie, in the office was also very efficient in booking the orginol Service up and even though they had to cancel the orginol date of booking, Libby in the office was very efficient in explaining why and re - scheduling the new date and time that suited me. Thanks again for excellent service, support and team work.

 Trustindex verifies that the original source of the review is Google. The team at Here4Heat have all been fantastic with our air conditioning installation. From our initial quote with Steve, liaising with Katie with any enquiries, and Dan, Danny, Kian and Jamie installing the system, the whole process has been seamless and exceptional. Everyone we spoke to was helpful, accommodating, and proffessional. We're extremely happy with the service and couldn't recommend Here4Heat highly enough. A massive thank you.

 Trustindex verifies that the original source of the review is Google. Josh and Kian did an excellent job installing air conditioning in the bedroom. They arrived on time and worked efficiently explaining to us what they were doing. They covered everything while they were working and left no mess. They were very friendly and had a good working relationship with each other. The result of their endeavours was a good night’s sleep in a cool bedroom! Thank you Josh and Kian

 Trustindex verifies that the original source of the review is Google. I am very satisfied with the work done at my property in July 2025 over six days. The installers (of a Bosch air source heat pump system, replacing a combi gas boiler) were friendly and professional, and respectful of my needs and my belongings. It was a difficult job because of the small space for the tank, but the result is very compact and neat. There were a few small problems, and communication was occasionally incomplete, but these difficulties were quickly and courteously corrected. My feedback has been welcomed, so I feel assured that the company will continue to give very good and reliable service in providing this new technology.

Frequently asked questions

Prices vary depending on the model and your home’s needs. During your free boiler survey, we’ll recommend the right Worcester Bosch boiler and provide a clear, fixed-price quote.

If your boiler is over 10–15 years old, keeps breaking down, or is no longer efficient, it may be more cost-effective to replace it with a modern combi boiler.

Most combi boiler installations are completed in 1–2 days. We’ll give you a clear timescale before starting work.

There may be a short period during installation, but our engineers aim to keep disruption to a minimum and get your heating back on as quickly as possible.

Yes, all our Worcester Bosch combi boilers come with long manufacturer guarantees (up to 12 years) for peace of mind.

Absolutely! You can book your free boiler survey online in minutes, and our team will confirm a date that suits you.
