Putting up a deck is permitted development. You will not need planning permission, provided:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">The decking is no more than 30 cm above the ground.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Together, with other extensions, outbuildings, etc, the decking or platforms cover no more than 50 per cent of the garden area.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">None of the decking or platform is on land forward of a wall forming the principal elevation.<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">If your deck is more than 600 mm above ground level, you will need balustrades. Balustrades must be at least 1,100 mm high, with no gap wider than 100 mm, to ensure safety. Stairs require handrails.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">If you live in a listed building or a conservation area, or in suburban and terraced housing zones, you can expect stricter regulations. If your deck connects to a secondary space, for instance, further rules may apply.

Most homeowners find that direct access to their home\u2019s indoor kitchen is best for indoor-outdoor egress. Will you use your space to entertain? Does a simple grill area suffice, or does a full-blown outdoor kitchen fit your entertaining needs? If quiet evenings spent reading sound like paradise, privacy may be your focus. Determine how you\u2019ll use your space and then design the zones you need.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Safety considerations should be paramount. Overloaded decks can deteriorate, especially in the damp weather conditions found in the UK. Reinforced concrete footings and steel supports may be needed for heavy structures such as hot tubs, pergolas, outdoor kitchens, and furniture. A properly designed and built deck resists tilting, sagging, loosening fasteners, and even collapse.<\/span><\/p>\n<h3 class=\"small-header\">Material Matters<\/h3>\n<p><span data-preserver-spaces=\"true\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4505 alignleft\" src=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2023\/06\/37914120836_69d087c014_o-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2023\/06\/37914120836_69d087c014_o-300x225.jpg 300w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2023\/06\/37914120836_69d087c014_o-768x575.jpg 768w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2023\/06\/37914120836_69d087c014_o.jpg 1001w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>The materials you use to build your deck will make the biggest impact on your enjoyment of it. Timber is the most popular, readily available, and affordable material choice for decking and balustrades. The downside to timber is the heavy maintenance requirements to keep the deck safe and looking good over time. <\/span><\/p>\n<p><span data-preserver-spaces=\"true\">A premium alternative to timber is wood-plastic composite decking, such as <a href=\"https:\/\/uk.trex.com\" target=\"_blank\" rel=\"noopener\">Trex<\/a>, the market leader, offering balustrades that can be mixed and matched with the same proven performance. Offered in a wide range of beautiful colours and made from an eco-friendly mix of recycled plastic film and reclaimed timber, Trex composite decking boards are easy to maintain and last for decades with a simple soap and water cleanup.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">While timber requires sealing and staining every 1-2 years and will rot and warp without careful attention, composites won\u2019t rot, splinter, fade or stain. Composites cost more initially than timber, but you can <a href=\"https:\/\/uk.trex.com\/build-your-deck\/planyourdeck\/decking-comparison\/\" target=\"_blank\" rel=\"noopener\">recoup the cost<\/a> within a few years.<\/span><\/p>\n<h3 class=\"small-header\"><span data-preserver-spaces=\"true\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4072 alignright\" src=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2022\/09\/IMG_6779-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2022\/09\/IMG_6779-300x225.jpg 300w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2022\/09\/IMG_6779-1024x769.jpg 1024w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2022\/09\/IMG_6779-768x577.jpg 768w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2022\/09\/IMG_6779.jpg 1440w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/span><\/h3>\n<p><span data-preserver-spaces=\"true\">Whatever material you choose for your decking, consider using <a href=\"https:\/\/trexprotect.com\/uk\/materials-estimator\/\" target=\"_blank\" rel=\"noopener\">Trex Protect<\/a> Joist, Bearer, and Rim tape. This butyl tape provides a protective barrier against moisture and condensation, keeping your timber substructure stronger for longer.

Measure your deck footprint and mark the corners with stakes.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Run string lines between stakes to outline the deck perimeter. Measure diagonals, too, to ensure it is square.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Clear the site by removing grass, weeds, trees and shrubs within and close to your deck\u2019s footprint. Strip topsoil by taking away 5-10 cm of the top layer<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Level the ground along the string lines. Scrape down high spots and fill low spots with a compacted sub-base such as crushed stone to achieve a flat surface.<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">It\u2019s crucial<\/span><span data-preserver-spaces=\"true\"> to have a strong and sturdy foundation.<\/span><span data-preserver-spaces=\"true\"> There are <\/span><span data-preserver-spaces=\"true\">a number of ways to build a deck foundation. Your choice will depend upon the slope of your yard, deck height, soil conditions, and load requirements.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">The most common include:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Concrete posts\/footings (best for raised, heavy decks)<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Deck blocks or pad stones (quick, ground-level)<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Adjustable pedestals (urban\/rooftop or uneven ground)<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Ground screws (sloped sites, eco-friendly alternative)<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Helical Piles (ideal for heavy structures, <\/span><span data-preserver-spaces=\"true\">difficult<\/span><span data-preserver-spaces=\"true\"> terrain)<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Existing slabs\/concrete bases (for simple low-level decks)<\/span><\/li>\n<\/ul>\n<h3 class=\"small-header\"><span data-preserver-spaces=\"true\">Phase 3: Installing the Frame<\/span><\/h3>\n<p><span data-preserver-spaces=\"true\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4694 alignright\" src=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam-300x169.jpeg\" alt=\"\" width=\"300\" height=\"169\" srcset=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam-300x169.jpeg 300w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam-1024x576.jpeg 1024w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam-768x432.jpeg 768w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam-677x383.jpeg 677w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/flush.-beam.jpeg 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>After choosing your posts or support columns, turn your attention to the rest of your deck\u2019s framing, which supports the decking boards above. The main elements for building the frame\/substructure are:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Ledger Board: Horizontal board secured to the house wall<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Bearers: Horizontal members supporting joists. Typically spaced every 1.8-2.5 m<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Joists: Repeated horizontal members that run perpendicular to the beams. Commonly spaced 400 mm to 600 mm centre-to-centre if using timber decking; 300 mm to 400 mm centre-to-centre if using composite decking<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Rim Joists or End Joists: Outer joists forming the perimeter of the deck frame and help to keep the interior joists square<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Noggins or Blocking: Short pieces installed between joists to add lateral strength and keep joists upright. Also serve as points for attaching balustrade posts or stairs<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Bracing: Diagonal structures added between posts or underneath joists on elevated decks<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">During the installation process, it\u2019s critical to periodically check that your foundation and frame are level. Some tips to keep in mind:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Start with a level foundation. All posts, blocks and footings should be set at the same height before laying bearers<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Use string lines and levels<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Always measure from the same reference point, such as a corner post or ledger end<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Check the level both lengthwise and widthwise across joists<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Recheck diagonals whenever you add a new rim joist or brace<\/span><\/li>\n<\/ul>\n<h3 class=\"small-header\"><span data-preserver-spaces=\"true\">Phase 4: Laying Deck Boards<\/span><\/h3>\n<p><span data-preserver-spaces=\"true\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4687 alignleft\" src=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13-300x169.jpg\" alt=\"\" width=\"300\" height=\"169\" srcset=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13-300x169.jpg 300w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13-1024x576.jpg 1024w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13-768x432.jpg 768w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13-677x383.jpg 677w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/08\/install-fasten-trex-decking-ch01-step13-13.avif 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>Adhering to correct gapping guidance is paramount when laying the decking boards. Gapping allows for drainage, airflow, and timber expansion, and varies depending on the decking material chosen. Timber tends to expand and contract due to changes in moisture, while composites tend to expand and contract due to temperature changes. Incorrect gapping can cause buckling or warping, while excessive gaps are unsafe and unsightly.<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Timber gapping: Leave 5-6 mm between boards, 2-3 mm at ends, and 10 mm at walls and other structures <\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Composite gapping: Manufacturers typically advise leaving 3-6 mm between boards, 3-8 mm at ends, and 10-15 mm between boards, walls, or posts.<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">Let your design style shine when laying out your decking boards. Here are a few orientation and installation tips:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Always lay out a few boards before fixing to ensure you like the look<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Diagonal and patterned designs use more material so consider that as you set your budget<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Run boards perpendicular to the house to create a traditional look. This popular design creates minimal waste and is good for small or narrow decks<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Add one or two deck boards around the perimeter at 90 degrees (a picture frame design) to add visual interest and also hide cut ends or scallops<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Run boards at 45 degrees to make small spaces look larger. Requires tighter joist spacing<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">A herringbone or chevron design creates an interesting parquet-like finish. Works best on larger decks<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">One or two boards that run perpendicular across the centre of the deck (breaker board) is often used to break up long runs of boards<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Alternate board widths or stagger lengths for a modern feel<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">It\u2019s easy to overlook the fasteners used to adhere decking boards to the frame, but this choice can make all the difference in performance and the aesthetic enjoyment of your space.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Generally, deck screws are the most practical and cost-effective option for budget or timber decks. Use stainless steel or coated screws to avoid the corrosion that comes with standard screws and nails. For a clean, seamless look with no visible screw holes, use hidden fasteners on composite decks. <\/span><\/p>\n<h3 class=\"small-header\"><span data-preserver-spaces=\"true\">Phase 5: Finishing Touches &amp; Clean-Up<\/span><\/h3>\n<p><span data-preserver-spaces=\"true\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4695 alignleft\" src=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-258x300.jpeg\" alt=\"\" width=\"258\" height=\"300\" srcset=\"https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-258x300.jpeg 258w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-881x1024.jpeg 881w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-768x892.jpeg 768w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-1322x1536.jpeg 1322w, https:\/\/trexprotect.com\/uk\/wp-content\/uploads\/sites\/5\/2025\/09\/image0-1763x2048.jpeg 1763w\" sizes=\"auto, (max-width: 258px) 100vw, 258px\" \/>If you have an elevated deck, you\u2019ll need <a href=\"https:\/\/uk.trex.com\/products\/railing\/\" target=\"_blank\" rel=\"noopener\">balustrades<\/a> and perhaps even steps. There are myriad balustrade options to choose from. Timber is the most cost-effective and readily available material, but you can elevate the look of your deck with aluminium, steel, and composite balustrades featuring infills such as glass and mesh, as well as round or square composite or aluminium balusters.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Finishing the sides of your deck with decorative skirting or fascia can give your outdoor space that little something extra. Choose simple white PVC trim or composite fascia that matches the composite decking boards.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Due to the UK&#8217;s wet, cool climate, decks may require extra care to maintain their appearance over time. Both timber and composite decks benefit from regular cleaning and maintenance. <\/span><\/p>\n<p><span data-preserver-spaces=\"true\">For timber decks, applying a wood preservative protects against weather damage, rot, moss, algae, and insect infestations. This is especially critical for shaded gardens. Decking oils repel water, keeping the boards from flaking and disintegrating. Reseal every 1-2 years.
