Quick Answer
DIY interior painting costs around £200–£500 in materials for a 3-bedroom house. Hiring a professional costs £1,500–£4,000. DIY saves money but takes 2–3 weekends of your time and rarely achieves the same finish quality on complex areas. For visible rooms, high ceilings or extensive woodwork, a professional is usually worth the investment.
Painting is one of the most tempting DIY jobs — after all, anyone can hold a brush. But in 2026, with decorator day rates at £150–£250, the decision isn't as simple as it looks. Whether DIY or professional is the right choice depends on your budget, available time, the condition of your walls, and how much the end result matters to you. This guide gives you an honest comparison to help you decide.

For a standard 3-bedroom semi-detached house, typical DIY material costs are:
- Emulsion (walls and ceilings): £80–£160 (trade 5-litre tubs)
- Gloss or eggshell (woodwork): £30–£80

Quality: What Professionals Do Differently
An experienced decorator produces a noticeably better finish for several reasons:
- Cutting-in: The skill of painting a clean line where wall meets ceiling or skirting without masking tape. Professional decorators cut in freehand with a brush in a single pass — achieving a sharper line than masking tape in many cases. This takes years of practice.
- Prep quality: Professionals spot and fix problems (hairline cracks, damp patches, flaking paint) that homeowners miss. Good prep is the foundation of a lasting finish. See our guide on wall preparation.
- Paint application technique: Even roller coverage without lines, drips or "holidays" (missed areas) requires experience. Professionals work systematically and quickly before paint dries.
- Woodwork finish: Smooth, drip-free gloss or eggshell on skirting boards, door frames and doors is genuinely difficult to achieve without experience and the right brushes and technique.
- Consistent colour: Professionals apply consistent coat thickness, avoiding the patchy appearance that can result from uneven DIY application.
Time Investment
Time is the factor most homeowners underestimate. A 3-bedroom house painted professionally in 4–5 days takes most DIY homeowners 3–5 weekends — sometimes more. Factor in:
- Moving furniture in and out of each room
- Waiting for coats to dry (you can't use the room during this time)
- Making good any mistakes
- Weekend time that could be spent on other things
For a detailed time breakdown, see our guide on how long it takes to paint a 3-bedroom house.
If your time is worth, say, £25/hour and you spend 40 hours on a DIY repaint, that's £1,000 of your time — closing the gap with professional costs significantly.
When DIY Is the Right Choice
DIY painting makes the most sense when:
- You're on a tight budget and the finish is less critical
- The rooms are in good condition and need a simple refresh
- You have experience and enjoy decorating
- It's a utility space (utility room, loft room, rental property)
- Ceilings are standard height (2.4m)
- There's minimal woodwork or the woodwork doesn't need repainting
- You have flexibility on timing and can spread the work over several weekends
When to Hire a Professional Decorator
Professional decorating is worth the investment when:
- The finish matters — living room, master bedroom, hallway in a period home
- Ceilings are higher than 2.5m (safety and practicality)
- There's extensive woodwork (mouldings, cornicing, panelling)
- Walls need significant prep (stripping wallpaper, filling large areas)
- You're using expensive designer paints and want them applied properly
- Time is short — you need it done in days, not weekends
- You're selling the house and kerb appeal matters
For external painting specifically, always hire a professional — working at height for exterior painting is dangerous without proper scaffold or equipment.
How to Find a Good Decorator
When hiring a decorator, follow these steps to get the best outcome:
- Get at least 3 quotes — prices vary significantly, and the cheapest isn't always the best value
- Ask to see examples of recent work — ideally visit a completed job or see photos
- Check they carry Public Liability Insurance — essential if they damage anything in your home
- Look for Painting & Decorating Association (PDA) members — a useful quality indicator
- Get a written quote itemising prep, coats of paint, materials and what's excluded
- Ask how long they've been trading and for references from recent customers

Frequently Asked Questions
Is DIY painting worth it to save money?+
It depends on your situation. DIY saves £1,000–£3,500 on a full 3-bed house repaint, but costs you 20–40 hours of your time and typically produces a lower-quality finish. If budget is the priority and the rooms are simple, DIY is absolutely worth it. If quality matters or your time is valuable, professional is usually the better choice.
What is the biggest difference between professional and DIY painting?+
The finish on woodwork and the cutting-in on edges. Rolling walls is something most people can do reasonably well. But painting skirting boards, door frames and architraves without drips or brush marks, and cutting in a clean line at ceiling/wall junctions — these are skills that take years to master. This is where the visible quality difference shows.
Can I do my own prep and hire a decorator just to paint?+
Yes — some homeowners do the filling, sanding and washing themselves, then hire a decorator for the painting. This can reduce the decorator's time and cost. Make sure you discuss this arrangement upfront and the decorator is happy to work with pre-prepared walls. Some prefer to do their own prep to ensure quality.
How do I get a fair price from a decorator?+
Get at least three quotes for the same scope of work, specifying which rooms, whether woodwork is included, and whether prep is included. Ask each decorator to quote based on an identical specification. The cheapest quote isn't always the best — look at what's included and the decorator's experience.
Do I need to supply the paint or does the decorator?+
Either way works. Many homeowners choose their own colours and supply the paint — this gives full control over quality and colour. Decorators often have trade accounts and can buy paint at a small discount, sometimes passing on savings. If you supply your own paint, buy it before the decorator starts and make sure there's enough — running out mid-job causes delays.
