Terms and conditions of the Big Boiler Shop Service Contract
Annual boiler service.
The annual boiler service includes the standard safety and performance check as required by the manufacturer to keep your warranty valid (see more about the annual service here). Should any of the required tests show that a boiler strip down or parts are required, the cost for this is not covered under the service contract.
Gas safety check on other appliances.
When relighting all other gas appliances after completing the boiler service, we will also check them to ensure they are not posing a danger to you or your property. Please note this is only a basic check and if any issues which pose possible danger or risk to life are found, we will be required by law to stop the supply of gas to that appliance.
Annual smoke and carbon monoxide alarm test.
The test on the smoke and carbon monoxide appliances will be carried out once the property owner or responsible person has identified to the engineer the location of such appliances. We will test your smoke or carbon monoxide alarm by pressing the test button if one is present. If the alarm does not give off an audible signal we will advise that this is the case, this often means the appliance will need replacing. We will not provide a replacement as part of the service pack or supply free replacement batteries.
Extended help and support
It is advised that you attempt a free telephone call before using your free 1hr callout per year as you may need that in an emergency. The free 1hr callout will only be available between the hours of 8 am and 4 pm Monday to Friday and from first contact we have 72 hours to attend the property.
Priority Saturday boiler servicing
On a first come first serve basis and only available between the hours of 8 am and 2 pm. At this time we do not offer exact slots but aim to give 1hr notice of arrival.
Fixed price service pack
For a minimum of 5 years (maybe longer dependant on inflation) the service pack is fixed at the rate at which you receive at the start of your cover. However, should you miss a payment or temporarily cancel for whatever reason, a new service pack will begin and this may have a higher cost.
Annual system water check
If the system water fails a quality check we will flush the system with your approval and add a new bottle of system inhibitor inclusive on the service contract. Only one bottle of inhibitor is provided with the service pack every two years if required. Please note, if the inhibitor is deemed not necessary on your system, there is no partial refund of the service contract price.
