Wardrobes, chests of drawers, kitchen units bought separately from an installation, garden storage boxes: flat-pack furniture is quick to buy and slow to build alone, especially anything over a single-person lift. Assembly is priced per item rather than by the hour, so the cost is known before the van arrives.
TV mounting is the other regular request, checking the wall type before drilling so a plasterboard wall gets proper fixings rather than screws straight into board that won’t hold the weight. Cables are routed neatly rather than left hanging, and the bracket is levelled properly rather than eyeballed.
Beyond those two, this covers the general list of small jobs that don’t fit neatly under repairs, painting or the garden: shelving, curtain poles, picture hanging in bulk, minor lock adjustments. A single wardrobe assembly typically costs £45; a full morning of mixed small jobs is quoted as a half-day rate instead of itemising each task separately.
