Standard hourly rates

This applies to most jobs including leaks, boiler faults and breakdowns – but please call the office for clarification.  During the first hour, we will diagnose and hopefully get the issue resolved for you.  If the issue is not something we can resolve within the hour it will then go onto our half hourly rate.  However within the first hour we should be able to diagnose the problem, advise you of the fault and how much longer we estimate the repair to take and whether any parts are required to complete the job.  We try to be as fair as possible and apply the half hourly rate so that if we are at your premises another 20 minutes after the first hour, you are not charged for a full 2 hours.


Fault finding on combination boilers so we can diagnose your issue is about solving the problem. The process of diagnosing a boiler fault includes engineers’ investigation based on their training, experience and expertise.  In some instances engineers will need to call for technical advice to manufacturers for example or they may need to look in the boiler manual. This is all part of diagnosis.  Sometimes, boiler repairs can be a process of ellimination and sometimes multiple parts may be failing which is not always clear.  Our professional heating engineers, through their years of experience and training as a professional service and repair engineer, demonstrate technical expertise within the industry and know when they should call on technical advice or utilise information from other sources.

Boiler Servicing

There are different types of boiler services and the type we carry out as standard is an interim boiler service which means that we don’t just lift the boiler case and take the pressure filters.  We clean the Magnaclean, condense trap, drain the boiler in some instances, check pressure vessel on boiler and other checks needed.

There is also an option to have a strip and clean boiler service which is usually advised by manufacturers every 4-5 years and includes changing boiler seals and in some cases will need doing due to readings not meeting manufacturers instructions.  If your boiler is over 4 years old and you haven’t had it serviced regularly the service may take longer and additional charges may apply due to the variation in boilers.
