    My boiler wasn't heating the water properly for about a week. It would go hot and cold constantly when ever I had a shower. Found 123 heat online and booked an appointment. I had a call from a engineer straight away to confirm my booking. The following day James the engine turned up on time as agreed and fixed the boiler within 45 minutes. Was very happy with the service and price. I would definitely use them again and recommend them to friends and family.

    Just had a Worcester Bosch combi installed in my loft. The engineer was friendly, efficient and made a fantastic job of all the pipe work and he took all the rubbish away with him too. I would highly recommend 123 Heat.
    Fantastic service from start to finish. British Gas condemned my boiler and said it was beyond economical repair. I searched online and found 123 Heat. Website is easy to use and explains everything you need to know, I filled in the contact page after picking a boiler and I received a phone call within 5 minutes. Within half an hour I had a new boiler organised to be fitted the following day. Engineer arrived at 8am, polite, fitted the new boiler and cleared all rubbish. He also explained everything I needed to know about the boiler and controls before he left. I would highly recommend using this company.
    New combi boiler and three radiators fitted. High standard of work carried out, disposed of all rubbish and left the place clean and tidy. Polite, courteous and professional throughout. Highly recommended.
