Quick Answer: The best places to buy plastering and building supplies in the UK are Wickes, Screwfix, Travis Perkins, Jewson, and B&Q. Trade accounts at merchants like Travis Perkins offer 10-20% discounts, whilst DIYers often find competitive pricing at Screwfix for tools and Wickes for materials. For professional plastering work, specialist suppliers stock British Gypsum products, Knauf boards, and professional-grade tools that aren’t always available in general DIY stores. Understanding the UK Home Improvement Store Landscape The UK building supplies market has evolved significantly, with distinct tiers catering to everyone from weekend DIYers to professional tradespeople. Knowing where to shop can save you hundreds of pounds on a typical plastering or renovation project. The hierarchy typically breaks down into three categories: trade-only merchants (Travis Perkins, Jewson, Buildbase), trade-friendly chains (Wickes, Toolstation, Screwfix), and general DIY retailers (B&Q, Homebase). Each serves a purpose depending on your project scale, timeline, and budget. According to the Office for National Statistics, the UK building materials sector generates over £50 billion annually, with online sales growing rapidly post-pandemic. This shift means competitive pricing is now easier to find than ever. Essential Plastering Materials: What to Buy and Where Professional plasterers and serious DIYers need to understand which materials are worth investing in versus where you can economise. Here’s the breakdown by material type. Plasterboard and Drywall Systems Standard 12.5mm plasterboard remains the most common specification for walls and ceilings in UK construction. In 2026, expect to pay between £6-£10 per sheet at trade counters, whilst DIY stores charge £8-£12. British Gypsum dominates the UK market with their Gyproc brand, but Knauf and Siniat offer comparable quality at slightly lower prices. For specific applications, you might need: Moisture-resistant boards for bathrooms and kitchens (£10-£14 per sheet) Fire-rated boards for conversions requiring 30-60 minute fire resistance (£12-£18) Acoustic boards for reducing sound transfer between rooms (£15-£25) Thermal boards with integral insulation for external walls (£20-£35) We’ve covered the benefits of thermal plasterboard for improving energy efficiency in detail on another guide, which is particularly relevant given 2026’s Building Regulations Part L requirements. Plasterboard Type Trade Price (per sheet) DIY Store Price Best Supplier Standard 12.5mm (2400x1200mm) £6.50-£8.50 £8.50-£12.00 Travis Perkins, Jewson Moisture-resistant 12.5mm £10.00-£12.00 £12.00-£14.00 Wickes, B&Q Fire-rated 12.5mm £12.00-£15.00 £15.00-£18.00 Specialist merchants Acoustic 15mm £18.00-£22.00 £22.00-£25.00 Travis Perkins Finishing Plasters and Skim Coats Multi-finish plaster (also called board finish) is the industry standard for skim coating plasterboard in the UK. A 25kg bag covers approximately 10-12 square metres at 2-3mm thickness and costs £8-£12 depending on supplier. British Gypsum’s Thistle Multi-Finish dominates the market, but Knauf MP75 and Tarmac Limelite offer comparable performance. Professional plasterers often prefer British Gypsum for consistency, whilst cost-conscious renovators find Tarmac products 15-20% cheaper. Multi-Finish: Universal skim for boards and backing plasters (£8-£12 per 25kg) Board Finish: Specifically formulated for plasterboard surfaces (£8-£11) Easifill: Rapid-set filler for repairs and patches (£6-£9 per 10kg) One Coat: Modern gypsum plaster requiring no skim coat (£12-£16 per 25kg) For more detail on proper application techniques, our guide on skimming plaster for a perfect finish covers everything from mixing ratios to trowel techniques. Backing Plasters and Base Coats Before applying finishing plaster, most solid substrates require a backing coat to create a level surface with the correct suction. The choice depends on your substrate: Browning: For absorbent backgrounds like brick and blockwork (£7-£10 per 25kg) Bonding: For low-suction surfaces like concrete and painted walls (£8-£11 per 25kg) Hardwall: Impact-resistant base coat for high-traffic areas (£8-£12 per 25kg) Dri-Coat: For walls with historic damp issues requiring breathability (£15-£20 per 25kg) Pro Tip: Buy plaster in bulk if you’re tackling multiple rooms. A full pallet (56 bags) at Travis Perkins typically works out £1.50-£2.00 cheaper per bag than buying singles. Store unused bags on pallets off the ground in a dry location—plaster absorbs moisture and becomes unusable within weeks if stored improperly. Tools and Equipment: Trade Quality vs Budget Options The right tools make an enormous difference in plastering quality and speed. Professional-grade equipment costs more upfront but lasts years with proper care, whilst budget tools often need replacing after a single large project. Essential Plastering Hand Tools Every plasterer needs a core toolkit. Here’s what professional tradespeople actually use daily versus what you can economise on: Tool Budget Option Professional Option Where to Buy Plasterer’s Trowel (11-14″) £12-£20 (OX) £40-£65 (Marshalltown, Refina) Screwfix, Travis Perkins Hawk/Hand Board £8-£15 (plastic) £25-£40 (magnesium) Toolstation, Jewson Bucket Trowel £6-£10 £12-£18 Screwfix Corner Trowel (internal) £10-£15 £20-£30 Trade merchants Devil Float £8-£12 £18-£28 Wickes, Travis Perkins Mixing Paddle & Drill £35-£60 (750W) £120-£200 (1400W) Screwfix, Machine Mart Marshalltown and Refina are the gold standards for trowels, with blades that maintain their flex for years. Budget trowels from brands like OX work adequately for DIY projects but lose their spring after 50-100 square metres of work. We’ve written comprehensive guides on Refina plastering tools and OX plastering tools comparing specifications and value for money across ranges. Power Tools and Mixing Equipment A 1400W mixing drill with variable speed control is essential for consistent plaster mixing. Cheaper 750W models overheat and burn out when mixing multiple bags daily. Budget £120-£150 for a reliable unit from DeWalt, Makita, or Bosch. The mixing paddle matters as much as the drill. Spiral paddles (£15-£25) suit most plasters, whilst helical designs (£25-£40) reduce air entrainment for smoother finishes. Buy these at Screwfix or Toolstation where they’re consistently cheaper than trade counters. Dustless sanding systems: £80-£350 depending on whether corded or battery (Mirka, Festool) Plaster mixers: £300-£1,200 for forced-action mixers on larger commercial jobs Laser levels: £40-£300 depending on accuracy requirements and self-levelling features Protective Equipment and Dust Control Under the Health and Safety Executive construction regulations, proper respiratory protection is mandatory when working with gypsum dust. A basic FFP2 mask (£1-£2 each) suffices for occasional DIY, but professional plasterers should invest in reusable half-mask respirators (£25-£60) with P3 filters. ⚠️ Warning: Respirable crystalline silica (RCS) is present in many building materials including sand-based renders and
