Questions people ask first.
More on the help page.
What does the visit fee cover?
Getting to you, finding the fault and the first hour of work. It is £89 in the day, £129 in the evening (6pm to 8am) and at weekends, and £69 if you book a slot for a later day. Prices include VAT where it applies.
What if the job needs more than an hour, or parts?
Your engineer sends a fixed quote to your phone, built from our price list. Nothing more is done or charged until you approve it. If you say no, you only pay the visit fee.
When am I charged?
The visit fee is held on your card when you book and only charged when your engineer arrives. Any approved extra is charged when you sign the job off. You can cancel free of charge until the engineer sets off.
How do I know who is at my door?
You see your engineer’s name, photo and van registration before they arrive. At the door they show a four-digit code on their phone that matches the one on yours.
Who are the engineers?
Independent, self-employed tradespeople. Before anyone joins we check their public liability insurance and, for gas work, their Gas Safe registration. Engineers are not sent jobs once either has run out.
What is the guarantee?
Work paid for through Mains is guaranteed for 12 months. If the same fault comes back, tap “The problem has come back” on your receipt and we book a free return visit.
