- 1Protect, patch & clean
- Clear the room and cover floors, stairs and doorways you walk through
- Fill holes and cracks; patch-plaster any big damage
- At the end: hoover, wipe down, remove protection
- 2Electrics
- First fix: electrician runs new cables and back boxes before plastering
- Second fix: sockets, switches and lights connected after decorating
- Electrician tests it all and gives you a certificate. Keep it for when you sell
- 3Paint walls, ceiling & woodwork
- Fill, caulk gaps and sand
- Mist coat on new plaster, then ceiling first
- Two coats on walls
- Woodwork last, in satin
- 4New flooring
- Underlay rolled out, boards left in the room 48 hours first
- Undercut door frames so the floor slides under
- Lay the boards, 10mm gap at the walls
- Door bars and scotia beading to finish
- 5Skirting & architrave
- Old skirting and architrave off carefully
- New lengths cut, mitred and fixed with grab adhesive and pins
- Fill nail holes, caulk the top edge, then paint
- 6Finishing touches
- Light fittings and new socket fronts on (power off at the fuse board)
- Blinds or curtain poles up
- Door stops on so handles don't hit the new paint
Easy to forget
- Flooring goes down after painting, so it doesn't get splashed
- Book the electrician early: first fix is before plastering, second fix after
- Order everything at least a week before you start. Waiting on one part stops the whole job
- Keep 10% spare. Old houses always hide something behind the walls
Questions people ask
How much does a home office renovation cost in Northern Ireland in 2026?
A mid-range home office renovation costs about £1,900 – £2,500 for a typical 3 × 2.7 m room with trades doing the work, including materials, labour and a 10% contingency. Budget finishes start lower and premium can cost a lot more; see the table above.
How long does a home office renovation take?
About 4.5 working days of trade time on site. Allow roughly 1 week start to finish, longer if you do parts yourself.
How much can I save by doing some of it myself?
Doing the DIY-friendly work yourself (protect, patch & clean, paint walls, ceiling & woodwork, new flooring, skirting & architrave, finishing touches) saves about £900 on a mid-range home office. Leave electrics to qualified trades.
Do I need building control approval?
Usually not for a like-for-like refit. You will normally need building control approval if you remove or alter walls, change drainage, make a new opening for a window or door, add a toilet or bathroom where there wasn't one, or install or replace a boiler. If in doubt, ask your council's building control team before you start.
