Think of a lamp post base as the shoe for your garden light: it’s small, but it changes how everything looks and how long it lasts. A proper base keeps the lamp upright, protects wiring, and completes the aesthetic. Whether you’re lighting a winding path, framing a driveway, or adding a vintage touch to a patio, the right base turns a simple post into a reliable feature that feels intentional and finished.
Not every base is right for every post. There are a few common types you’ll see across UK shops and online retailers, and knowing the difference helps you pick with confidence.
Spike bases are like tent pegs for lamp posts — you push or drive them into the ground. They’re ideal for soft soil and temporary or seasonal lighting. Expect spikes to go down about 8 to 12 inches into the soil for light-duty posts, and up to 18 inches for heavier fixtures. Aurora-style spike mountings are popular for garden path lights and for cases where digging a full concrete footing isn’t practical.
Base plates bolt the post to a flat surface such as a patio slab, stone pier, or a concrete pad. These plates give a clean, secure mounting and are perfect for hard surfaces where spikes won’t work. Collingwood-style base plates often include pre-drilled holes so you can drop anchor bolts straight through and set the post solidly on a slab or plinth.
Extension pieces let you raise the height of an existing post without changing the base. They’re handy when you want more reach for light spread or to match surrounding fixtures. For example, an extension might add 1 to 3 feet of height while keeping the same base footprint. Choose textured finishes to hide small scratches and maintain grip between joined sections.
Shopping for lamp post bases in the UK is easier than it looks. Some stores cater specifically to lighting, others to general DIY — and each has its strengths. Below are retailers that either appear in lighting-focused listings or are widely known for supplying outdoor lighting parts.
Downlights outlets often stock a broad selection of bases and accessories designed to pair with decorative and functional outdoor lights. You’ll find spike mounts for planting beds, base plates for patios, and metal extension poles to tweak height. If you’re chasing a particular finish or a matching mounting option for a branded post, Downlights-style retailers are a good first stop.
Expert Electrical shops are geared toward both trade and home users and typically stock technical items like extension poles, weatherproof base plates, and electrician-friendly accessories. They’re a smart choice when you need compatibility—say, matching an Astro extension pole to an existing pole system—or when you want components with clear technical specs for a long-term installation.
B&Q is a go-to for many homeowners because it mixes value with convenience. You’ll find a variety of lamp post bases here: simple spike mounts, decorative base plates, and basic extension pieces. Their in-store displays can help you visualise how a base will sit on patio slabs or lawns.
Wickes is another high-street option that offers both functional and decorative lighting hardware. They’re useful for people doing larger garden projects because you can often buy anchors, fixings, and concrete at the same time as the base. If you’re pouring a small concrete pad, Wickes makes sourcing everything easier in one visit.
Screwfix tends to focus on sturdy, trade-grade solutions. If you want heavy-duty base plates, high-grade anchor bolts, or specialist extension collars that hold up to frequent wind and damp, Screwfix-style shops are where tradespeople turn. Their selection favours durability and practical compatibility.
Online specialists like Lighting Direct offer curated ranges that include matching bases, bespoke finishes, and accessories from well-known lighting brands. They’re a great resource if you’re hunting for a particular colour or a cast-iron base to match a heritage-style post. Expect more variety and style-focused options than in general DIY chains.
The material of a base affects how it weathers and how much maintenance it will need. Let’s break down common choices so you can match durability to budget and style.
Cast iron bases have a classic look and plenty of weight for stability. They fit traditional lamp posts beautifully, but they need a rust-inhibiting coating or regular touch-ups—especially near the base where water can pool. Cast iron feels solid underfoot and suits older properties or Georgian-style gardens.
Aluminium is light, won’t rust, and is easy to handle when installing. It’s a good choice for coastal properties where salt air speeds up corrosion. A powder-coated aluminium base can give you vibrant colours and a low-maintenance finish that lasts seasons without flaking.
Stainless or galvanised steel bases are practical and robust. Galvanised steel is often used for base plates that will be bolted down and may get stomped on or come into contact with moist ground. Stainless steel offers a sleeker modern look and resists staining and rust.
For very lightweight posts or temporary displays, composite or reinforced plastic bases can work. They don’t have the longevity of metal but are cheap, easy to move, and won’t rust. Use them for seasonal fixtures or where weight and portability matter more than permanence.
Installing a lamp post base ranges from a ten-minute bolt-down to a full foot of concrete work. Your choice depends on ground type, post weight, and whether wiring runs under the surface. If you’re comfortable with basic tools, you can tackle many base fittings yourself. For hard-wired lighting or posts over 7 feet tall, it’s often worth hiring a qualified electrician for safety and compliance.
If you’re using a spike mount, loosen the soil and remove stones to get a solid insertion. For base plates, make sure the slab or plinth is level. If pouring a small pad, dig a hole roughly 12 to 24 inches deep and backfill with concrete to create a firm plinth for the anchor bolts.
Light-duty garden posts can sit comfortably on 12 inches of compacted base or a small concrete pad. Heavier or taller posts will need deeper foundations—aim for 18 to 24 inches of well-compacted concrete for strength and frost protection. Think of the foundation as an underground anchor; it stops wobble and keeps wiring safe from drainage issues.
Water, freeze-thaw cycles, and ground movement are the biggest threats to outdoor electrical connections. Make sure any wiring through the base uses weatherproof gland seals and is rated for outdoor use. Where wires pass through metal bases, protect the bundle with cable sleeves or grommets to prevent chafing and corrosion over time.
Choosing the right height and design is part art, part arithmetic. A small lamp post looks lost next to a two-storey house; an oversized fixture dominates a tiny courtyard. A good rule of thumb: match the post height to the surrounding architecture—garden borders and path lights often sit at around 3 to 5 feet, while driveway posts can range from 6 to 9 feet. Use proportions like you would when picking furniture: balance, not overwhelm.
Regular checks will keep your base and post looking and performing well. Every spring and autumn, inspect anchor bolts for tightness, check for signs of rust or flaking paint, and clean any debris sitting around the base that could trap moisture.
For metal bases, a simple annual coat of rust-inhibiting primer and paint goes a long way. If the base is near sprinklers or pond edges, give it a wipe-down more frequently. Touch up scratches quickly to prevent them becoming future rust patches.
The smart approach to longevity is modularity: choose a mount system where spikes, plates, and extension pieces can be replaced separately. That way, if a post needs raising or the bottom corrodes, you can swap out a single component rather than replacing the whole assembly.
Prices vary widely depending on material, brand, and finish. Basic spike mounts and simple base plates start at modest prices, while heavy cast-iron base plates and branded extension poles can be more of an investment. As a rough guide, expect entry-level options from about £15 to £30, mid-range plates and spikes around £30 to £80, and premium cast-metal bases or branded extension kits from £80 up to £200 or more.
When pairing a base to a post, match the screw hole pattern and pole diameter first. If you have a branded post or a specific fitting, check the technical sheet for base compatibility. If in doubt, bring photos and measurements to the store—or compare product specs online from specialist lighting retailers if you’re ordering from home.
If you’re thinking of solar lamps or low-voltage systems, many bases are compatible with slimmer solar posts or low-voltage cabling. For smart gardens, choose bases that allow discrete cable runs so sensors and smart bulbs can link back to a hub without spoiling the look.
Don’t forget the small details: matching the finish of your base to door hardware, garden furniture legs, or guttering creates a cohesive outdoor space. A textured black extension pole, for example, pairs well with dark metal furniture and creates a contemporary yet understated backdrop for foliage and flowers.
Want to see how different bases look in real gardens? High-street stores often have displays, while specialist online retailers show photos of installed fixtures. Social platforms and home-improvement forums are also great for before-and-after shots and real-world tips from people who’ve done the work themselves.
Choosing the right lamp post base is a small decision with big impact. From spike mounts for soft beds to heavy base plates for stone patios, the correct base keeps your post steady, safe, and stylish. Visit specialist lighting retailers like Downlights or Expert Electrical for brand-specific parts, and consider mainstream DIY stores for affordability and convenience. With the right materials, a sensible foundation in inches and feet, and a little routine maintenance, your outdoor lighting will stay bright and beautiful for years.
