Every 12 months for rented properties. You can have the check done up to two months before the deadline and keep the original renewal date.
Usually 30 to 60 minutes, depending on the number of gas appliances in the property.
We'll explain what's wrong and whether it's safe to use. If it's dangerous we'll make it safe, and we can quote to repair or replace it so the property can pass.
