Terms & Conditions

1)    Any amendments to the original order will need to be made in writing, and the quotation can be adjusted accordingly.

2)    All quotations are provided free of charge and with no obligation to proceed. All quotations will be based on the information made available at the time and could be subject to change under certain circumstances.

waived if you choose S T Plumbing and Heating Gas Specialists Ltd to complete the necessary repairs as diagnosed.

4)   Upon a final heat loss calculation of the installation, the system design can be subject to change to increase the efficiency without alteration to the costing

5)    Where the flues pass through an outside wall, we will use all reasonable endeavours to ensure that when filling the hole, this matches the existing wall finish, but exact matching cannot be guaranteed.

6)    Carpets/flooring may need to be lifted to install pipework. In such an event, S T Plumbing and Heating Gas Specialists Ltd endeavour to return the carpet/ flooring to as near as original condition as possible. Although it is important to note that we are heating engineers, not carpet fitters, therefore, no liability can be accepted for any damage caused to carpet / flooring, unless caused by our negligence.

7)   Whilst working on site we will always endeavour to protect your possessions and property; however, it is the responsibility of the householder / occupier to protect all belongings, in areas work is being carried out. S T Plumbing and Heating cannot accept liability for damage to possessions, unless caused by our negligence.

8)    Power flushing to remove debris from a central heating system can, on rare occasions, expose previously undetectable faults, weak points, or breaches. S T Plumbing and Heating Gas Specialists Ltd cannot be held responsible for any such pre-existing conditions which might be revealed, or for any resulting damage which may occur.

9)    Installing a new boiler will not affect individual radiators or cause them to cease working. If there are pre existing faults with the radiators on the system they may need to be replaced; resulting in an additional charge.

10)    When installing a new boiler, it may come to light that new pipework may also need to be installed due to a difference in diameter between existing pipework and the new boiler. In such cases an additional charge may be incurred.

11) When converting any pipework from static head pressure to fully pressurised we do need you to be aware that, when we fit the new appliance, the system must be pressurised. If there is any old pipework or radiators in place, the pressurisation can sometimes highlight any issues and/or corroded pipework, radiator or ball valves may leak or become defective. We do not accept responsibility for any problems which arise due to the integrity or suitability of the existing system to which the new boiler is connected. We can replace pipework or radiators if required, but any cost related to this would be chargeable.

12)  All gas and water piping will be installed and insulated according to appropriate standards. Pipe work will be concealed, wherever possible; however, this will be at the discretion of S T Plumbing & Heating Gas Specialists Ltd

15)  The customer will have 31 days from the initial quotation in which to accept.

16)  No liability can be accepted for any damage caused by substandard partition walls, that do not have the adequate support for load bearing items.

17)  It is the customers / contractor’s responsibility when fitting new fix radiators and or pipework as part of any third party works, to ensure that the plans are available for our engineer before works commence or an agreed location for the radiator and or pipework has been made with the third party, in writing, prior to installation.

19) Tap Repairs:

A dripping tap can be caused by a variety of reasons, dependant on the type of tap and its components.

Worn out washers, Faulty ‘O-rings, corroded valve seat, ceramic disc damage, worn out cartridge or worn out seals. If one of the following are identified as being faulty by our engineers and there are no manufacturer’s instructions available, we can remove the components to try and match upon request; however, this disturbance could potentially cause the leak to worsen and if unable to find matching spares, could result in the tap itself having to be isolated and or replaced. As such, S T Plumbing & Heating accept no liability in the event of this occurrence.

20) Unvented cylinder servicing

An unvented cylinder service will include the checking and or testing of the temperature controls, pressure controls and relief valves and built in safety devices, to ensure that they are operating correctly; therefore, failure of any of these associated controls and or valves under test conditions, is not the responsibility of  S T Plumbing & Heating and no liability is accepted for any replacement parts that may be required.
