We would like to apologise for any inconvenience caused by the recent loss of your gas supply, which was due to water entering Mayfair’s local gas network.

All the affected properties have now been visited by one of our engineers and supplies restored where we have been able to gain access.  If our engineers have called and been unable to gain access, may I ask you to contact National Grid gas enquiries on 0845 605 6677 to arrange a time for your gas supply to be reconnected.

All National Grid employees carry an official identify card containing a photograph.  Please ask to see this before allowing anyone in the property. For further advice on this, please call the National Grid enquiry line.

Important – Please do not attempt to reconnect your own gas supply or relight appliances. You must wait until an engineer calls to carry out this operation to ensure your gas system is working safely.

Over the next few weeks, affected properties will be compensated under our guaranteed standards of service, in line with the following compensation arrangements:

• Properties used for domestic purposes only, will be entitled to £30 for every complete 24 hour period without gas - up to the point at which we first visited the property to re-connect the supply.

• Properties used for non-domestic purposes only (for example shops), will be entitled to £50 for every complete 24 hour period without gas - up to the point at which we first visited the property to re-connect the supply.

• Non-domestic properties with an annual consumption that exceeds 73,200kwh (for example large commercial or industrial users) should check their gas supply contract for the applicable arrangements, or contact their gas supplier.

Affected properties will receive compensation via their gas bills without a claim having to be made.  Should you have any queries regarding the above compensation please contact National Grid Customer Services on 0845 0700203 option 1. For information about matters beyond the specific payments outlined above, please contact Thames Water.

If you have any concerns about your gas supply or can smell gas please contact the National Gas Emergency Service on 0800 111 999 (calls will be recorded and may be monitored).
