Anchors hold pictures, but anything heavy — shelves, TVs, radiators — goes into a stud. Use a stud detector, or knock the wall: a solid thud means stud, a hollow note means plasterboard. UK studs are usually 400–600mm apart.
Brown plugs suit masonry with a 7mm hole, red are for lighter loads. For plasterboard use spring-toggle or self-drive metal anchors — ordinary plugs just spin and pull out.
Drill a pilot hole within 25mm of the end of any board before driving a screw. It stops the grain splitting and keeps your joints tight.
Always dry-fit and clamp a joint first. If anything sits crooked now it'll be ten times worse once PVA is in the mix and the clock is ticking.
Finish every sanding pass along the grain, not across it. Cross-grain scratches are invisible on bare wood but scream the moment you apply oil or stain.
Thin coats dry faster, drip less and give a tougher finish. Let each coat dry fully and lightly key between coats with fine sandpaper for a pro result.
Run a thin, steady bead of caulk, then drag a damp finger along it in a single smooth pass. Stopping and starting mid-bead leaves a seam you'll see forever.
Turn off the supply at the stopcock (plumbing) or consumer unit (electrics) before any work, then prove it's off. Open a tap or test the circuit — never trust the switch alone.
Wrap PTFE tape around threaded fittings in the direction the nut tightens (usually clockwise), 3–4 turns. Wrong way and it just unravels as you screw it on.
Modern UK wiring: brown = live, blue = neutral, green/yellow = earth. Older installs use red (live) and black (neutral). If in any doubt, stop and call a registered electrician.
In England & Wales, new circuits and most bathroom/kitchen electrical work fall under Part P and must be done or certified by a competent person. Swapping a like-for-like socket is fine; rewiring is not.
Re-check every measurement from the same reference edge so small errors don't stack up. Mark with a sharp pencil — the saw bevel rides a fine line for a cleaner cut.
A blunt bit burns and wanders. Match the bit to the material — masonry bits for brick, HSS for metal, brad-point for clean holes in wood. Let the tool do the work; don't force it.
Wipe the surface and the level's edge before checking. A speck of grit or old paint throws the bubble off enough to ruin a run of tiles or shelves.
