DIY or Hire a Painter?
The most DIY-able home trade — but cutting in still wins on price. Last reviewed April 2026 by the TradeMatch editorial team.
Painting and decorating is the most DIY-able UK home trade by volume — over 70% of UK households have painted at least one room themselves in the last five years per the Decorators and Painters Association (DPA). Modern paint chemistry (low-VOC water-based eggshell, one-coat coverage, mist-coat-friendly emulsions) has lowered the skill barrier substantially since the early 2000s. The decision is rarely about competence — it is about time and finish. A skilled DIY-er can paint a 4m × 4m bedroom to a respectable finish in a weekend; a pro decorator does the same room in 6 hours to a noticeably sharper finish. The economic crossover is at the cutting-in: edge work to a clean line is the single skill professionals trade on, and it is the slowest part of any DIY paint job.

The DIY-vs-pro decision rule for painter work
DIY makes obvious sense for single rooms, simple cuboid spaces, and fresh-on-fresh repaints over an existing similar colour. Hire a pro for whole-house repaints (they will be quicker per square metre and the finish is consistent across rooms), high-up exterior work (a 3m+ ladder is a pro-safety category), and any wallpaper job (paste-the-wall, lining paper, complex pattern matches). The biggest DIY trap is the "easy" two-day job that becomes a ten-day job because of bad prep — flaking patches not stabilised, gloss not deglossed before re-coating, masonry not stabilised before exterior emulsion. Pros spend 60% of the job on prep; DIY-ers usually spend 20% and pay for it in the finish.
Three painter jobs you can confidently DIY
- Single-room repaint over an existing similar colour — fill any small holes, mist coat new plaster (1:4 emulsion), one finish coat, done
- Refreshing skirting boards and architraves with a one-coat satinwood — a 50mm angled brush + 30 mins prep gets a respectable result
- External fence and shed treatment — Cuprinol or Ronseal one-coat shed paint, dry day, no scaffolding needed if it is at ground level
Three painter jobs to never DIY
- Whole-house repaints across multiple rooms — a pro does it in days at a consistent finish; DIY across 4-5 rooms typically becomes inconsistent and takes 3-4× longer
- Wallpaper hanging — paste-the-wall and pattern matching are skilled trades; a £200 hanging fee saves £400+ in wasted rolls and stripped-back redos
- Exterior masonry / soffit / fascia work above 2m — Working at Height Regulations 2005 apply; ladder accidents are the leading cause of UK home-DIY hospital admissions per HSE
UK regulations that apply to painter work
Painting itself is not regulated in the UK — anyone can call themselves a painter. The relevant rules are around lead paint (any home built before 1992 may contain lead-based paint; sanding produces a regulated waste under the Control of Lead at Work Regulations 2002), Working at Height (Working at Height Regulations 2005, applicable to any ladder use 2m+), and waste disposal (paint is hazardous waste; cans cannot be put in domestic recycling). For listed buildings, paint specifications and colour are controlled by Listed Building Consent; using the wrong product can result in enforcement action.
DIY cost vs hiring a UK painter
| Approach | Typical Cost |
|---|---|
| DIY | £40-£80 in paint and brushes per average UK bedroom (4m × 4m, two coats) |
| UK pro | £300-£500 for the same room fully prepped, painted and tidied (typically 1 day for one decorator) |
Honest summary: On a single room, DIY saves £250-£400 of labour. On 5+ rooms or any whole-house refresh, the pro is faster, cleaner and the finish is dramatically more consistent — typically the better economic call once labour-day count exceeds 5.

DIY vs Pro Painter — FAQ
How much faster is a pro painter than a DIY-er?
About 3× on like-for-like prep — a pro decorator paints around 12-18m² of wall surface per hour after prep; a competent DIY-er paints 4-7m². On full prep (filling, sanding, masking) the gap widens to 4-5×.
Is it worth painting one room myself if I am hiring a pro for the rest?
Usually no — pro decorators offer a meaningful per-room discount when doing 4+ rooms in one visit, and a single self-painted room often clashes in finish quality, making the pro work look worse by comparison. Bundling pays.
What is the most expensive DIY painting mistake?
Painting over old gloss without sanding it back to a key. The new coat fails to bond, peels in 6-12 months, and stripping it later costs more than having the original job done by a pro. Always sand or de-gloss before any new gloss or satinwood coat.
Do I need a permit to paint the outside of my house?
For a normal house, no. For listed buildings or houses in a Conservation Area, you may need Listed Building Consent or a planning application — check with your council. Render colour changes on Conservation-Area homes are particularly tightly controlled.
