had boiler service by british gas last month when he installed a hive thermostate system was cleaned then partner has rang british gas about it but still waiting on a response

Thank you Ray, this is a failed main control board. What its doing is sending hot water to the taps and to the radiators. Or you may simply have a short in the circuit.
The best thing to do is have the tech return and check this for you.
I have seen this many times in my 30 + years as a technician.
I will stick with you until this is fixed, please don't forget to rate my service to you before you close this page. I will be available to you at no additional cost , you can then get in touch with me anytime by simply replying to this message.
Thank you Ray and have a great day!
