Good to know

Questions people ask.

Do you charge a call-out fee?

No. You pay for the job, not for us turning up. If we can’t fix it on the first visit, we tell you why and what it will cost before going any further.

Are your engineers Gas Safe registered?

Yes, every engineer who works on gas is Gas Safe registered, and they’ll show you their ID card at the door. We’re fully insured too.

Do you work evenings and weekends?

Our office hours are Monday to Saturday, but the emergency line runs 24/7 for no heating, no hot water and leaks you can’t stop.

How do I pay?

By card or bank transfer once the job is finished and you’re happy. For new boilers we take a small deposit, and you can spread the rest over monthly payments.

Will you clean up afterwards?

Always. Dust sheets down before we start, all old parts taken away, and we check everything works with you before we leave.
