We are your Technical Eyes in reviewing your dispute to help having it resolved 





We would firstly advise that there are organisations which will give free advice on the matter, in particular C.O.R.G.I (Confederation of Registered Gas Installers),

NOW called GAS SAFE,(

should the installation be considered in breach of the Gas Safety (Installation and Use) Regulations currently in force.

If the gas boiler has been replaced, do you have the mandatory Gas Safe -  gas completion certificates to ensure a full check on the existing gas installation complies with such regulations?

It is incumbent on the installer to ensure that any new connections/alterations or amendments to an existing gas supply, comply fully with the above regulations.

Are the installer’s sure that they have fully complied?

Did the the company ensure that the operatives, carrying out the work, are all Gas safe registered. Should you find that either the company or the operatives are not then this matter in itself is reportable to the Health and Safety Executive, who will prosecute for the offence.

N.I.C.E.I.C (National Inspection Council for Electrical Installation Contracting).

( ) If any minor electrical works have been carried out to the central heating, do you have the mandatory NICEIC completion certificate? (Depending on the nature and extent of the electrical works carried out).

If the companies involved are members of organisations which have a redress policy, such as:-

The Institute of Plumbers /The National Association of Plumbing Heating and Mechanical Services Contractors

( ) or the

Heating Ventilating Association ( ) which has now become the Building Engineering Services Association - (as an example)

then you could approach these member associations or similar to have the matter resolved.

There are however certain issues on which we can advise as detailed below and we are happy to assist at no cost to you at this time if you are able to provide the information as detailed below:-
