How to Choose the Right Painter and Decorator in London: Complete Checklist

How to Choose the Right Painter and Decorator in London

Hiring a painter decorator in London is a decision that directly affects your home — the quality of the finish, how long it lasts, and whether the experience is smooth or stressful. London has thousands of painting contractors, from sole traders to large firms, and the difference between the best and the rest can be stark: a finish that lasts 8 years versus one that needs redoing after 18 months. This guide covers exactly what to look for, what questions to ask, and the red flags that should make you walk away.

What to Look for in a London Painter and Decorator

1. Experience With Your Property Type

London's housing stock is extraordinarily varied. A painter who is excellent with modern new-build flats may have no experience with Victorian period properties — and the two require completely different approaches. Period properties often have lime plaster, which needs breathable paints. New builds have drying plaster that needs mist coating. Ask specifically: "Have you painted properties like mine before?" and "What special considerations does my property type need?"

An experienced interior painter London should be able to identify your property's era, wall construction, and any potential issues within minutes of walking through the door. If they can't tell you whether your walls are lime plaster or gypsum, they're probably not the right choice for a period property.

2. Insurance and Guarantees

Any professional painter decorator should have:

• Public liability insurance — minimum £2 million cover. This protects you if they damage your property or a third party's property. Ask to see the certificate — don't just take their word for it.
• Workmanship guarantee — typically 2–5 years against peeling, blistering, or premature failure (excluding wear and tear). Get this in writing.
• Paint manufacturer's guarantee — quality trade paints like Dulux Trade, Johnstone's, and Crown Trade come with 5–15 year manufacturer guarantees when applied according to specification.

3. Written, Itemised Quotes

A proper painting quote should never be a single figure scrawled on the back of a business card. It should detail:

• Every room or area to be painted, with dimensions
• Preparation work included (filling, sanding, caulking, priming)
• Number of coats (minimum two for walls, three for new plaster)
• Specific paint brands, products, and finishes to be used
• Number of painters on the job and estimated duration
• What's included and excluded (furniture moving, floor protection, waste removal)
• Payment terms and schedule
• Start date and estimated completion date

At Painter Decorator London, we provide this level of detail on every quote. This transparency protects both you and us — there's no ambiguity about what was agreed.

4. Portfolio and References

A painter who's proud of their work will have photos. Look for:

• Before and after photos — not just after shots
• Close-up detail shots — cutting-in around skirting boards, light switches, and window frames reveals true skill
• Photos of similar properties — if you have a Victorian terrace, look for examples of period property work

Ask for references from clients in the last 6 months. When you call, ask: "Was the work completed on time and on budget?" "Was the property left clean and tidy each day?" "Would you hire them again?" and "Have you noticed any issues since completion?"

5. Professional Accreditation

Membership of professional bodies isn't essential, but it's a positive signal. Look for:

• Painting and Decorating Association (PDA) — the UK's main trade body
• Checkatrade or TrustATrader membership — vetted and reviewed tradespeople
• Dulux Select Decorator — a scheme run by Dulux for decorators who meet their quality standards
• TrustMark — government-endorsed quality scheme

Questions to Ask Before Hiring

When you meet a potential painter decorator for a quote, ask these specific questions:

1. "What preparation will you do before painting?" — A good answer covers filling, sanding, caulking, priming, sugar-soaping greasy walls, and protecting floors and furniture. A bad answer is "we'll just paint over it."
2. "What paint brand do you recommend and why?" — They should name specific trade brands (Dulux Trade, Johnstone's Trade, Crown Trade) and explain why, not just say "whatever you want." Trade paint is significantly different from retail paint — better coverage, better durability, better value overall.
3. "How many coats will you apply?" — Correct answer: minimum two coats on walls, three on new plaster (mist coat + two top coats), two on ceilings, and two to three on woodwork depending on colour change.
4. "How do you protect my furniture and floors?" — They should describe dust sheets (canvas, not polythene), masking tape on skirting and fixtures, and possibly moving furniture to the centre of the room.
5. "What happens if I'm not happy with something?" — They should have a clear snagging process. Professional painters expect to return for minor touch-ups — it's completely normal.
6. "Can I see your public liability insurance certificate?" — They should say yes immediately. Any hesitation is a red flag.

Red Flags to Avoid

Some warning signs that should make you reconsider:

• Quote significantly below others — If three quotes are £2,000–£2,500 and one is £1,200, they're cutting corners somewhere. Likely on preparation, paint quality, or both.
• Large deposit demanded upfront — A small deposit (10–20%) is reasonable to secure a booking. Demanding 50% or more upfront is not normal for painting work.
• No fixed address or landline — A mobile-only contact with no verifiable business address is a risk. How do you find them if something goes wrong?
• Vague about timeline — "We'll fit you in" or "it takes as long as it takes." Professional decorators give specific timeframes.
• No written contract or quote — Never accept a verbal quote alone. If they won't put it in writing, walk away.
• Pressure to decide immediately — "This price is only valid today." Reputable painters don't use high-pressure tactics.
• Can't provide references — Everyone starts somewhere, but even a new painter should have someone who can vouch for their training or previous work.

London Pricing: What's Reasonable?

Painting costs in London vary significantly. Here's what to expect for a professional job using quality trade paint (prices include preparation, materials, and two coats):

• Single room (4m × 4m): £400–£700
• Two-bedroom flat (entire interior): £2,000–£4,000
• Three-bedroom house: £3,500–£6,000
• Four-bedroom house: £5,000–£8,000
• Staircase, hall, and landing: £800–£1,500

These are ranges for painting only — wallpapering, specialist finishes, extensive plaster repairs, or exterior painting cost extra. For a more detailed breakdown, see our complete London painting cost guide.

What About "Cheap" Painters?

Everyone loves a bargain, but painting is one area where cheap almost always costs more in the long run. The difference between a £400 room and a £700 room is typically:

• Preparation time: 2 hours vs 6 hours. The £400 painter skips filling, sanding, and priming.
• Paint quality: Retail paint at £25 per 5L vs trade paint at £45 per 5L. Trade paint covers better, lasts longer, and usually works out cheaper per square metre of coverage.
• Coats: One coat vs two. One coat always looks patchy, especially with any colour change.
• Clean-up: Minimal vs thorough. The cheap quote often doesn't include proper protection or clean-up.

You're paying the same room to be repainted again within 2–3 years — often spending more overall than if you'd hired a quality painter from the start.

Getting the Best Result

Even the best painter can only work with what they're given. To get the best possible finish:

• Clear the room as much as possible — the more they can access, the better the finish
• Make decisions before work starts — changing paint colours mid-job causes delays and can affect the quote
• Be available for questions on day one — painters often discover issues (damp patches, loose plaster) that need your input
• Trust their expertise — if they recommend against a particular colour or finish based on your room's lighting or condition, listen
• Inspect work at the end of each day — it's much easier to fix issues as they go than after the job is "finished"
