The Housing Executive is calling on all tenants to ensure they allow its contractors access to complete the annual safety check of gas boilers.
If they do not they are in danger of having their supply cut off.
As a landlord, the Housing Executive has a legal obligation to carry out an annual gas safety check.
Tenants may also face a charge for reconnection. This is a last resort but will be carried out if required.
Gaining admittance has proved a real problem with almost 400 ‘no access’ cases across Northern Ireland, four of those in Coleraine since September.
Mark Alexander, the Housing Executive’s Area Manager, said: “Gas safety in the home is paramount.
“I urge any tenant who has not had their gas boiler checked to work with our contractors to ensure this safety check is carried out.”
