Toolstation
Three taps between the problem and the fix.
No forums. No hedged AI answers. No guessing which cartridge fits your tap. The whole thing takes under a minute.
- 01
Point the camera.
Snap the drip, the crack, the flickering socket. One sentence of context if you have it — otherwise the photo is enough.
- 02
Get a real verdict.
We name the fault, grade the difficulty, estimate the time, and flag anything that belongs to a Gas Safe or NICEIC pro.
- 03
Buy the exact parts.
One-tap search across B&Q, Screwfix and Toolstation — with a curated best-pick where we've handled the job before.
Safety first
We built Fetlin because homeowners keep paying £90 call-out fees for jobs that take fifteen minutes and a £3 part. And keep watching YouTube for jobs that quietly need a Gas Safe engineer.
Safety before ego.
Gas, mains electrics, asbestos, structural and mains-water jobs are always flagged and routed to a Gas Safe or NICEIC-registered pro.
Honest about limits.
If a photo isn't good enough or the fault is genuinely ambiguous, we say so. We'd rather punt than sell you the wrong £40 part.
British stock. British prices.
Everything we recommend is in stock at a UK retailer today, at a UK price, in imperial or metric as the trade actually uses it.
Pay for the fixes you keep. Not the app.
Three diagnoses on the house. Upgrade only when Fetlin has already saved you a call-out.
