Cost to Paint a House Interior
Understand what you’ll pay before you pick up a brush or hire a decorator.
Painting a house interior typically costs £800–£2,500 when hiring a decorator, depending on property size, surface condition, and finish quality. DIY brings costs down significantly, mainly to paint and materials. A standard three-bedroom house sits in the middle of that range.
What Affects the Cost
Property size and room count are the biggest cost drivers. A one-bedroom flat requires far less material and labour than a four-bedroom semi-detached. Decorators typically price per room or per day, so every additional room adds directly to the total.
Surface condition has a significant impact. Walls with hairline cracks, blown plaster, or old wallpaper that needs stripping require preparation work before paint goes on. If your walls need repair first, see our Walls & Plastering Guide for what those remedial jobs might involve.
Paint quality and finish type affect material costs noticeably. Trade-quality paints cost more per litre but often cover better in fewer coats, potentially reducing labour time. Your choice of finish — matt, silk, or eggshell — also influences price; read the Matt vs Silk Paint Guide to understand the trade-offs before specifying a finish to a decorator.
Number of coats required affects both time and material spend. New plaster, dark existing colours, or a switch to a much lighter shade typically demand two or three coats. More coats mean more paint and more labour hours.
Woodwork and ceilings add cost if included. Skirting boards, door frames, architraves, and ceilings are often priced separately from walls. Including all woodwork in a full interior repaint pushes total costs towards the higher end of the range.
Access and furniture can also increase the price. Rooms with high ceilings requiring tower scaffolding, or heavily furnished spaces that need extensive masking and moving, take longer and may attract a surcharge from tradespeople.
UK Average Cost Breakdown

|---|---|---|---|
| Single room (walls only) | £30–£80 | £150–£350 | Assumes reasonable surface condition, two coats |
| Single room (walls, ceiling & woodwork) | £60–£130 | £250–£500 | Full room finish including skirting and door frames |

| Hallway, stairs & landing | £50–£120 | £300–£600 | Complex access often increases labour time |
| Surface preparation (per room) | £10–£40 | £50–£150 | Filling, sanding, priming — varies with condition |
DIY vs Tradesman — Is It Worth It?
Interior painting is one of the most accessible DIY tasks for homeowners. The tools are inexpensive, the techniques are learnable, and mistakes are usually fixable. If you are reasonably careful and prepared to take your time with preparation and cutting in, you can achieve results close to a professional finish at a fraction of the labour cost. Our guide on how to use a paint roller covers the core technique most beginners get wrong.
That said, there are situations where a decorator earns their fee. Hallways and staircases with tall walls and complex angles are genuinely difficult and potentially dangerous without the right access equipment. Rooms with poor surface condition — cracked, stained, or uneven plaster — require skilled preparation that significantly affects the final result. A professional will also work far faster; a job that takes you a long weekend may take a decorator a day.
The honest calculus: if your property is in reasonable decorative order, the rooms are straightforward, and you have the time, DIY is a clear winner financially. If the job involves difficult access, significant prep work, or tight timescales, the trade quote becomes much more reasonable relative to the outcome. For a full step-by-step approach, see the how to paint a room guide.
Regional Price Variations
Decorator day rates vary noticeably across the UK. London and the South East command the highest labour costs, where a decorator may charge £250–£350 per day compared with £150–£220 in the Midlands, North of England, Scotland, and Wales. For a whole-house repaint, this gap in day rates can translate to a difference of £400–£800 on the total bill for an identical property. When comparing quotes across contractors, always confirm whether the price is inclusive of materials or labour only, as this varies by region and individual trader practice.
How to Get the Best Price
- Get at least three written quotes from local decorators. Checkatrade and similar platforms let you compare verified tradespeople, but always request quotes in writing with a clear scope of work.
- Do your own preparation work. Moving furniture, filling minor cracks, and sanding woodwork before the decorator arrives reduces billable hours. Filling gaps around skirting boards before painting is one straightforward prep job — see our guide on how to fill gaps in skirting boards.
- Supply your own paint. Some decorators charge a markup on materials. Buying paint yourself (after agreeing the quantity with your decorator) can reduce costs, and you keep any leftover tins for touch-ups.
- Book during quieter periods. Decorators are typically busiest in spring and early autumn. Booking in January or February, or mid-summer, may give you more negotiating room on price.
- Bundle rooms together. A decorator will usually offer a better day rate for a larger, continuous job than for individual rooms booked separately.
What a Good Quote Should Include
- A clear scope of work — specifying which rooms, which surfaces (walls, ceiling, woodwork), and how many coats are included.
- Material costs broken out separately — or a clear statement that materials are supplied by the client, so there is no ambiguity about what is and is not included.
- Surface preparation included — light filling, sanding, and priming should be itemised. If it is not mentioned, ask specifically whether prep is included or priced separately.
- A start date and estimated duration — vague timescales are a common source of disputes. A reputable decorator will commit to a schedule in writing.
- Payment terms — a reasonable deposit (typically no more than 25–30%) with the balance due on satisfactory completion. Be cautious of any request for full payment upfront.
Hidden Costs to Watch For
- Wallpaper removal. If walls are currently papered, stripping before painting is a significant additional job. This is often priced separately and can add £100–£300 per room depending on how many layers are present and how well they come off.
- Plaster repairs. Cracks, holes, and blown plaster must be repaired and allowed to dry fully before painting. If a decorator identifies these on arrival, expect additional charges. Knowing your wall condition in advance — and addressing it yourself using the Walls & Plastering Guide — can prevent surprises.
- New plaster priming. Freshly plastered walls must be mist-coated before a finish coat is applied. Some quotes omit this step; if your walls have recently been re-plastered, confirm the mist coat is included.
- Access equipment. Stairwells or rooms with high ceilings may require a decorator to hire a hop-up platform or tower scaffold. This hire cost is not always included in the initial estimate and can add £50–£150 to the job.
Frequently Asked Questions
How much does it cost to paint a three-bedroom house interior in the UK?
For a three-bedroom house, expect to pay £1,200–£2,000 when hiring a decorator to paint walls, ceilings, and woodwork throughout. DIY material costs for the same property typically run £300–£600 depending on paint quality and the number of coats needed.
How long does it take a decorator to paint a house interior?
A professional decorator typically takes three to six days to paint the interior of a three-bedroom house, including preparation and two coats. Larger properties, complex prep work, or intricate woodwork will add time.
Do decorators charge per room or per day?
Both pricing models are common. Some decorators quote a fixed price per room after a site visit, while others work on a day rate — typically £150–£350 per day depending on location — plus materials. Always clarify which model applies before work starts.
How many coats of paint does an interior wall need?
Most walls require two finish coats for an even, durable result. New or freshly plastered walls need a diluted mist coat first, followed by two full coats. Covering a dark colour with a lighter one may need three coats.
Can I paint over old wallpaper instead of stripping it?
Painting over wallpaper is possible in some circumstances but is generally not recommended, as moisture from paint can cause the paper to bubble or peel. Stripping first gives a far better and more durable result.
Decorators price difficulty, not just size — a narrow hallway with a staircase often costs more per square metre than a large open bedroom because of the fiddly cutting in and access challenges. When requesting quotes, describe access honestly and ask specifically how the stairwell is priced.
