Market Size Research for Home Improvement
Home improvement is not one market. A litre of paint can be bought by a DIY consumer in a superstore or by a professional decorator at a trade counter, and the two volumes follow entirely different logic. Retail scan data misses the trade channel, trade data misses retail, and online volume slips past both. We size home improvement markets across the full picture: DIY consumers, professional painters, handymen, and fitters, with the channel splits that determine where your volume actually moves. Whether you need a TAM for power tools across Europe, the DIY versus professional split in decorative paint, or category volumes for a retail ranging negotiation, we combine online consumer surveys with phone interviews among trade professionals to produce figures that hold up. No extrapolation from retailer press releases.

What We Measure
TOTAL MARKET SIZE
Total Addressable Market (TAM): in volume and value, defined by your specific product category. For paint that means decorative emulsion vs. woodcare vs. specialist coatings in litres. For tools it means cordless drills vs. sanders vs. saws in units. For flooring it means LVT vs. laminate vs. solid wood in square metres. Served Addressable Market (SAM): the portion of TAM reachable given your price tier, retail listings, and trade channel coverage. A premium tool brand with no presence in discounters cannot serve the discounter volume, and the SAM should reflect that. DIY vs. DIFM split: the single most important structural number in most home improvement categories. We size the volume consumers buy and apply themselves separately from the volume professionals buy and install for consumers, because the two move independently and through different channels. Market size by occasion: full room renovation vs. repair and maintenance vs. decoration refresh. Category volumes per occasion differ, and so do the brands considered.
MARKET SHARE
Volume and value share by brand: actual purchase volumes reported by consumers and trade professionals over the past 12 months, not stated preference. Includes private label, which claimed-preference questions systematically undercount. Share by channel: DIY superstore, specialist trade store, builders merchant, garden centre, online pure player, supermarket. Your share in retail and your share at the trade counter are different numbers, and most strategic mistakes in this sector come from knowing only one of them. Share by audience: DIY consumers vs. professional decorators vs. handymen vs. kitchen and bathroom fitters. Trade loyalty patterns concentrate share differently from consumer choice. Year-on-year share movement: two-wave designs to track whether you are gaining or losing volume, in which channel, and against whom.
SEGMENT SIZING
Volume by product category: for paint, emulsion vs. gloss vs. exterior vs. woodcare by litres. For tools, by tool type and corded vs. cordless. For bathroom, sanitaryware vs. brassware vs. furniture vs. enclosures. For outdoor, by season-driven category clusters. Volume by buyer type: heavy DIYers vs. occasional decorators vs. DIFM-only households. Purchase frequency and basket value differ by an order of magnitude between these groups, and grossing up without separating them produces wrong totals. Volume by purchase trigger: moving house, room renovation, damage repair, seasonal maintenance. Trigger mix shapes both forecast logic and promotional strategy.
FORECASTING
3-5 year volume and value projections combining consumer intention data, professional pipeline indicators, and housing transaction and renovation trends. Channel shift modelling: online penetration by category, the trajectory of DIY superstores vs. specialist stores, and private label growth scenarios. Base case and upside/downside scenarios with stated assumptions on consumer confidence and housing market activity, the two macro drivers that move this sector most.
CHANNEL ANALYSIS
Volume split between retail and trade routes and direction of change by country. Online vs. physical split by category: tools and sundries travel online far more readily than paint or flooring, and the sizing model has to treat them differently. Retailer and wholesaler brand mix: which brands are gaining shelf space and trade counter presence, measured through retailer and merchant interviews.
Subsectors Covered
Subsector
Paint
Sizing in litres by product type, with the DIY vs. professional split as the core structural output. Private label share and trade counter loyalty make behavioral measurement essential. Brand share measured at both retail and trade channel levels.
Subsector
Hand and Power Tools
Units by tool type, corded vs. cordless, and consumer vs. professional grade. Online channel share is among the highest in the sector and needs its own sizing layer. Battery platform lock-in affects share dynamics.
Subsector
Flooring Products
Square metres by category (LVT, laminate, solid wood, carpet), with installation route (DIY vs. fitter) determining channel and brand dynamics. LVT growth rates differ sharply from legacy categories and need separate forecast curves.
Subsector
Bathroom Products
High consumer involvement but usually a professional installation decision. Sizing must cover the homeowner, the installer, and where relevant the showroom route, because each influences a different slice of volume.
Subsector
Kitchen Products
High-consideration purchase with strong interplay between retail formats, fitters, and designers. Sized by project value bands and purchase route (kitchen specialist, DIY retailer, online).
Subsector
Outdoor and Gardening
Seasonal and weather-driven volume requiring 12-month measurement windows and trigger-based segmentation. Channel split between garden centres and DIY superstores is a primary output.
Subsector
Decorative Sundries
Brushes, rollers, fillers, tape, and preparation products. High-frequency, low-ticket purchases where professional volume concentrates heavily and private label dominates parts of the retail side. Volume sized by category and channel.
This is a portion of the home improvement subsectors we cover.
How Market Size Research Works in Home Improvement - Example Project
A paint manufacturer wants the total decorative paint market in the UK, France, and Poland, split between the DIY and professional channels, by product type and by brand, to support a channel investment decision. We run online surveys (CAWI) with 300 consumers per country, screened for paint purchases in the past 12 months. Each respondent reports litres purchased by product type, the brands bought, the store or website used, and whether the paint was applied by themselves or by a professional. In parallel, we run CATI interviews with 100 professional painters and decorators per country, who report their annual litres by product type and brand, and where they buy: trade counter, superstore, or direct account. Bottom-up calculation: consumer-side volume grossed up using household population and category penetration rates, trade-side volume grossed up using the active professional painter population adjusted for business size. We reconcile the two sides, since DIFM volume appears in both consumer projects and professional purchases, and we cross-validate the total against production statistics and available retail data. Discrepancies are documented and explained. Output: total market in litres and value by country, DIY vs. professional split, brand share by channel, channel split including online, and a 3-year projection under base and accelerated online-shift scenarios. This is an illustrative example. Actual countries, respondent types, and methodology depend on your brief.
Target Audiences
This is a portion of the audiences we include in market sizing studies.
DIY consumers and homeowners
Core volume source for the consumer side of every category. Screened for category activity in the past 12-24 months so volume data comes from actual buyers. Reached by online survey (CAWI).
Professional painters and decorators
The critical trade audience for paint and sundries. Their annual litres, grossed up to the active professional population, form the trade-side bottom-up estimate. Reached by CATI.
Handymen and general contractors
Install flooring, fit bathrooms, and undertake full room refurbishments. A volume source that cuts across several categories at once. Reached by CATI.
Kitchen and bathroom fitters
Specialist trade professionals whose purchase volumes and wholesaler relationships shape brand share in their categories. Reached by CATI.
Interior designers
Specification influence rather than direct volume in most categories. Used to size the specified slice of premium segments. Reached by IDI or video call.
DIY and specialist retailers
Category managers provide sell-through perspective, ranging logic, and private label volume context. Reached by IDI or CATI.
Our Advantage
Market sizing in home improvement requires holding two markets in your head at once. We have researched this sector for over 30 years and we size the DIY and professional sides in one integrated design, with reconciled category definitions, so the totals add up. We know that consumer recall undercounts private label paint, that heavy DIYers distort grossed-up averages unless weighted separately, and that a professional decorator's brand loyalty makes trade share far stickier than retail share. A generalist agency running a consumer panel survey will miss the trade half of your market entirely.
Our trade fieldwork is phone-based by design. Painters, handymen, and fitters are not on panels in usable numbers, and panel substitutes corrupt volume estimates. We recruit trade professionals directly by phone across more than 20 countries. On the consumer side, our online fieldwork uses category-activity screening and volume plausibility checks, because a market size built on careless consumer data is worse than no estimate at all.
We also bring standing category benchmarks no generalist has. The European Home Improvement Monitor, Kitchen Monitor, Bathroom Monitor, and Painter Insight Monitor track purchase behavior, category volumes, and brand dynamics longitudinally. They calibrate bespoke sizing estimates against observed trend data and give your forecast a foundation in measured behavior rather than single-wave optimism.
Project Examples
Home Improvement - Market Sizing (Wallpaper)
A quantitative global market sizing study measured the wallpaper market across eight countries spanning Europe, Turkey, and South Korea. The study produced category volumes, purchase behavior, and channel splits on a harmonized basis across markets with very different decorating cultures. Results gave the commissioning industry body a comparable country-by-country view of market size and trajectory.
BE, FR, DE, IT, KR, SE, TR, UK
Home Improvement - Market Sizing (Painting Tools)
A quantitative market sizing study across the UK, Germany, and France measured painting tools volumes by category and by channel. The study separated consumer and professional volume and mapped the channel routes carrying each. The client used the output to prioritize category investment and channel coverage across the three markets.

Home Improvement - Segment Sizing (Wood Care)
A quantitative study in the UK and Germany sized the wood care and repair segment, covering market size, channel structure, pricing, and satisfaction drivers in one design. The study quantified segment volume and identified the dominant purchase routes. The client used findings to validate a category expansion business case.
UK, DE
Trade Channel - Market Sizing (Tile Adhesives)
A quantitative market sizing study in Greece measured the tile adhesives market among contractors and tile layers, an audience that overlaps heavily with home improvement fitting trades. The study produced brand share data and a segmentation by product type and distribution channel. The client used findings to assess market entry viability and identify the dominant route to market for their product format.

-
Why run primary research when retail scan data already exists for home improvement categories?
Scan data covers the retailers who sell it, which excludes the trade channel, most online pure players, and discounters in many markets. In paint and sundries the trade channel can carry half the volume or more. Scan data also defines categories by the retailer’s logic, not yours. Primary research sizes the whole market, both channels, defined by your product category, with brand share that includes private label and trade brands scan data misses.
-
How do you size the DIY versus professional split without double counting?
We measure both sides and reconcile them. Consumers report whether each project was done themselves or by a professional, and professionals report their purchase volumes directly. DIFM volume appears in consumer projects but in professional purchases, and our model assigns it once. The reconciliation step is documented in the methodology appendix so your analysts can see exactly how the two sides add up.
-
What sample sizes do you use, and how precise are the outputs?
On the consumer side, 200-300 CAWI respondents per country is typical, screened for category activity, with larger samples where penetration is low. On the trade side, 75-100 CATI interviews per trade type per country is the usual range. We provide confidence intervals on all estimates rather than single-point figures, and we recommend the minimum sample that makes the outputs defensible for your decision.
-
Can you run sizing across countries with very different retail structures?
Yes, that is the normal case. We harmonize category definitions and volume units across countries while adapting the channel framework to local retail structure, so a superstore-dominated market and a specialist-store market are measured on comparable terms. We have run home improvement sizing across Europe and in markets as different as Turkey and South Korea within a single harmonized study.
-
At what stage should we commission market sizing: before a category entry, or once we are in market?
Both are common. Before entry, sizing validates the business case and identifies the channel route that carries the volume. In market, annual sizing waves track share movement and channel shift, and they are the standard evidence base for ranging negotiations with retail buyers. If you are pre-entry, we usually pair sizing with a market exploration module so the volume numbers come with the distribution and competitive context needed to act on them.
-
How do you capture private label volume, which consumers rarely name?
By questionnaire design. We ask brand questions with structured prompts that include retailer own brands, we capture the store of purchase so own-brand inference can be validated, and we cross-check against retailer interviews on the channel side. Unprompted recall alone understates private label significantly, which is one of the main reasons generic consumer surveys produce wrong share numbers in this sector.
-
Can the output be used for M&A or investment due diligence?
Yes. The methodology appendix documents sample design, weighting, the consumer-trade reconciliation, and top-down validation in enough detail for a financial team to scrutinize the numbers. We report ranges and confidence intervals, not bare point estimates, and we state forecast assumptions explicitly so they can be stress-tested in your model.
