How much is a CP12 in Teesside?

£60 to £90 for a single appliance in 2026. A boiler and a gas fire checked in the same visit costs less than booking two separate certificates.

How often is a gas safety check needed?

Every 12 months for each gas appliance and flue you provide in a rented property. Doing it slightly early is fine and keeps the anniversary from slipping.

What if an appliance fails the check?

The defect is classified and recorded, and anything immediately dangerous is disconnected with your tenant informed. You then decide between repair and replacement, and a fresh record follows the fix.

Do I need one for a holiday let?

Yes. Short-term and holiday lets with gas appliances carry the same annual duty, and the record should be available to guests on request.

The duty, in plain terms

If you let a property with gas in it, the Gas Safety (Installation and Use) Regulations 1998 put three duties on you: gas appliances and flues checked for safety every 12 months by a Gas Safe registered engineer, pipework and appliances maintained in a safe condition, and the record given to your tenants. The record goes to existing tenants within 28 days of the check and to new tenants at the start of the tenancy, and copies are kept for two years. It applies to the appliances you provide: a tenant's own gas cooker is not yours to certify, but the flue and pipework serving it are still your responsibility.

What the engineer checks

Gas tightness of the installation and correct operating pressure at each appliance.
Flue performance, including a spillage test and flue gas readings where applicable.
Ventilation, so appliances get the air they need.
Safety devices proved to work, and the appliance's overall condition assessed.
Any defect classified and recorded, with unsafe appliances turned off with your tenant's knowledge.

Central Middlesbrough and the HMO reality

Teesside has a lot of rented stock, particularly the terraces of central Middlesbrough, Gresham, North Ormesby and parts of Hartlepool, and a good deal of it holds older boilers plus a live gas fire in the front room. Two appliances means two checks, which is why bundle pricing matters: booked together, the second appliance costs far less than a second attendance. Portfolio landlords with several properties in one postcode are usually cheaper again per certificate when the visits are grouped.

Certificate, service, or both

The gas safety record documents safety on the day. It is not a service, and it does not keep the boiler's manufacturer warranty alive. On a boiler under warranty, or on any appliance you would rather not see fail mid-tenancy, book the annual service in the same visit and get both jobs done for one attendance. Where an old appliance keeps failing its checks, the replacement conversation is usually cheaper than the third emergency callout.
