Emergency plumber call-out fees in London, explained honestly

A "call-out fee" is what you pay just for the engineer to turn up — before any work happens. In London in 2026, you'll typically see:

• £0 — "no call-out fee" (what we do): you only pay for work agreed and done on-site.
• £75–£120 daytime, £150–£250 nights & weekends: common at national franchises.
• First hour included: some firms charge a flat £180 covering the first 60 minutes of work.

The honest take: "no call-out fee" only matters if the per-hour or fixed-price work rate is also fair. Always ask for both before they set off — anyone reputable will give you a price range over the phone based on what you describe.

What to ask before they leave their depot: 1. What's the minimum charge if I send you away? 2. What's the labour rate per hour, including parts mark-up? 3. Are you Gas Safe registered, and what's the number? 4. Will I get a fixed quote in writing before work starts?
