Survey exclusions

Gas Safe registered engineers are required to follow the Gas Industry's Unsafe Situation Procedures (GIUSP) whenever they identify a dangerous gas appliance or gas installation. The GIUSP are specific safety tasks we must follow in order to protect people and property until any remedial works are completed to make the gas appliance or gas installation safe to use. The GIUSP requires extra works not included in our new boiler quote survey, so whenever we identify a dangerous gas appliance or gas installation, we explain why it's dangerous, discuss your options with you and charge a fixed fee of £30 to complete the safety tasks listed in the GIUSP.

Payment terms

Your site survey and no obligation quote is free from charge.

We operate a stage payment process, the amounts and terms are included in your new boiler information pack.
