Questions about ventilation for landlords and letting agents in County Antrim
Is the survey free in County Antrim?
Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
Is a landlord responsible for condensation and mould?
A landlord is responsible for the condition of the property, including adequate ventilation and heating, and serious damp and mould can be a hazard under housing law. Tenants also have to use the home reasonably, but ventilation that works without effort removes most disputes.
What is the best ventilation for a rental property?
For most rentals, humidity-controlled or continuous extract fans in the wet rooms plus a PIV unit gives reliable results that tenants cannot easily switch off. It typically costs £1,495 to £2,695 including VAT for a 2 to 3 bed home.
Which rules apply to ventilation in County Antrim?
In Northern Ireland, ventilation is covered by Technical Booklet K of the Building Regulations (Northern Ireland). Workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
