One of my radiators isn't working. What should I do?

Turn off all other radiators in the house, leaving the broken one on, to possibly remove an
air-lock.
If you have a pressurised heating system, make sure the pressure gauge shows 1 Bar.

There is no water in my heating system. What should I do?

Check if your neighbours have water. If they don't then it is a problem that affects the whole area and you should call your water supplier.
If your neighbours are not affected and if your cold water storage tank is in the roof, check to see if there's any water in it.
If you are the only property affected then it may be a system problem. Please call D W Dunn on 01285 771001.

Why can't you tell me exactly what time the engineer will arrive?

At the start of the day each engineer is given a list of jobs for that day. Sometimes the engineer is unable to say how long a job is likely to take until he has assessed it. Some jobs take longer than others if presented with unforeseen complications. This is why when booking an appointment we are unable to give a precise time.

Absolutely nothing! We offer FREE, NO OBLIGATION QUOTATIONS.

How often should I service my boiler?

Your boiler should be serviced annually, as recommended by manufacturers. The service entails checking, cleaning, testing and pre-emptive fault spotting, with the emphasis on testing all the different functions of an appliance for correct and safe operation.

What is a landlord's responsibility for gas and oil safety?

It is a legal requirement for gas appliances in rented properties to be checked at least once a year. We can do all the necessary checks and issue Landlord Safety Certificates.

It isn't law as of yet for oil appliances to be checked annually, however, we strongly recommend that this is done.

Will I get a shock when I recieve the invoice for the work you've done?

Once the engineer has identified the problem with your appliance, if any major parts are needed, we will always discuss with you the cost of works before going ahead with anything. So you will always be aware of what needs doing and how much it will cost.
