Our Process
We know that a broken boiler is often an unexpected and frustrating experience. We want to make the process of getting it back up and running as swift and painless as possible. To do this, we have produced the following guide so you know what to expect and how much it’s likely to cost.



Call us on 01704 834363 and explain your issue.
We will offer advice, check your boiler’s warranty and decide if an engineer call out is required.

you with expert advice.

Frequently Asked Questions
How can we help you?
If you have another question about repairs in mind, please give us a call.
Although most parts arrive the next day, on occasion they may take longer. To avoid having to postpone or cancel appointments, we have found that it is best to wait until parts have been delivered and we have checked that they are correct.
The majority of parts that we supply come with a one year warranty from our suppliers. We’ll do our best to let you know if this is not the case. Our workmanship comes with a two year warranty.
Our availability varies depending on the time of year and of course, the weather. Please call our office on 01704 834363 and we’ll be able to give you a better idea.
We tend to be in high demand throughout the winter months and during cold snaps.
The specifics of your gas appliance may also have a baring on how long you have to wait as we have to match an engineer’s experience and qualifications to your appliance (for example: Warm Air Units require a specialist qualification).
No, not usually. It is our policy to use our ‘tried and tested’ parts suppliers. That way we ensure that parts are genuine, unused and arrive in good condition. We can be sure that any warranty will be honoured then too.
In certain circumstances, such as if a manufacturer has provided you with replacement parts directly, we may vary from this policy, so please ask.
We use our knowledge and experience to diagnose the majority of faults correctly first time.
On the rare occasion that this doesn’t quite happen, our engineer will investigate and explain the situation to you so that you are fully aware of the solutions and associated costs. That way you can make an informed decision on how to proceed.
Whatever the reason, we promise that we always aim to provide you with an excellent service at a fair price
