Think of plumbing fittings and supports as the skeleton of your home’s water system — they keep everything in the right place, bear the load, and stop leaks before they start. Use cheap, mismatched parts and you’ll patch problems for years. Choose the right clips, clamps, valves and kits and you get quiet pipes, reliable water pressure, and fewer emergency calls. Whether you’re fixing a leaky basin or planning a full bathroom refit, choosing the correct components saves time, money, and stress.
Shopping for fittings? The UK market is full of options, from trade suppliers to high-street DIY chains. Below I break down the best places to source high-quality pipe clips, beam clamps, pressure-reducing valves and more — with a quick note on what each retailer does best so you can match the store to the job.
Expert Electrical stocks a strong selection of mechanical supports and plumbing accessories aimed at professionals and keen DIYers. If you’re after branded items like Walraven Britclips — threaded rod support clips, beam clamps and universal beam clips — this retailer often lists those exact components, ideal when you need reliable metalwork for suspended pipe runs. They also carry pressure-reducing valve kits and crossover valves for tap installations.
Screwfix is a go-to for many UK renovators because of fast local pickup and an enormous range that covers clip sizes, isolation valves, and pressure kits. They stock both branded and own-label goods, so you can compare premium options with budget alternatives on the same visit. If you’re doing a weekend job, Screwfix is hard to beat for speed and convenience.
Toolstation offers similar strengths to Screwfix — lots of branches, sensible prices, and plentiful stock. They’re especially useful for buying packs of clips, saddle clamps, and small accessory kits in bulk, and for picking up tools to match the fittings, like pipe cutters and crimping tools.
If you want to browse in person, B&Q and Wickes have ample showrooms with plumbing aisles that cater to household projects. These stores are ideal if aesthetics matter — for example, finished tap kits and decorative covers — and for homeowners who prefer shopping in a relaxed retail environment rather than a trade counter.
For serious plumbing work, trade suppliers such as Plumbase, Travis Perkins and City Plumbing carry the heavy-duty items: larger beam clamps, threaded rod assemblies, commercial pressure-reduction valves, and specialist brackets. These suppliers typically offer technical support and bulk-buy pricing for builders and installers.
Don’t forget specialist online shops and manufacturers’ websites if you need an exact part or specification. Brands like Walraven list product datasheets that help you choose exact clamp sizes and load ratings. For niche fittings such as speedflow kits and crossover tap valves, manufacturer stockists often have the best technical information.
Not all fittings are created equal. Knowing the differences helps you avoid buying the wrong part. Here’s a quick language guide to the main components you’ll see on supplier shelves.
Pipe clips secure plumbing to walls, ceilings or battens. They range from plastic saddle clips for copper or plastic pipe to heavy-duty cushioned metal clips for insulated runs. Choose a clip that matches the pipe diameter and allows a little movement for thermal expansion — rigid clips can cause stress and noise.
Beam clamps anchor your pipe hangers to structural steel. Products labelled “beam clamps with saddle” or “universal beam clip” give stable support for threaded rod hangers. For heavy runs, use beam clamps with locking units to prevent slippage; they’re worth the extra cost for long-term stability.
Threaded rod assemblies pair with clips and clamps to suspend pipework from ceilings. These are essential for lofts and commercial spaces. You’ll often see packs of threaded rod support clips sold to match rod diameter — buy the correct size and corrosion-resistant finish if it’s in a damp area.
PRVs (pressure-reducing valves) control incoming mains pressure to protect household plumbing. If your house has noisy pipes or you’ve got an older system with older fittings, a PRV set to the right pressure can quiet things down and reduce wear. Kits often include isolation valves and unions for easier replacement.
Crossover valves are used to simplify multi-function taps or create combined control setups from separate supplies. These small but clever fittings let you create a “4-in-1” tap setup or swap a standard mixer for a more compact arrangement without changing the entire valve body.
Although often associated with electrical work, trunking and saddle saddle clips can tidy and protect exposed piping and associated cables. Smaller trunking brackets keep runs tidy in plant rooms and utility areas, and spring clip saddles are handy for quick installations.
Expert Electrical lists several components that are popular with installers. For example, you’ll see packages of Britclips threaded rod support clips sized to fit small-bore pipe runs — think roughly 1 inch to 1¼ inches in diameter — sold in packs for multiple fixings. They also list beam clamps in bulk packs, universal beam clips, and combinations that include locking units to prevent movement.
Other items common to their range include pressure-reducing valve kits for domestic systems, crossover valves used in modern tap kits, and Speedflow kits that provide a compact solution for connecting pipework. If you value convenience, packs of 50 or 100 clips make life easier and cheaper than buying single items.
Choosing the correct piece is less about brand loyalty and more about matching material, size, and rating to your job. Here are six simple rules I use every time I shop.
Brass and stainless fittings resist corrosion in wet areas; plastic clips are great for lightweight runs. If your pipes run through a damp cellar or external area, opt for corrosion-resistant finishes like zinc or stainless steel.
Pipes expand and contract with temperature. A clip that fits too tightly will pinch the pipe; one that’s too loose won’t give stable support. Measure the outside diameter in inches and buy the closest fitting size — cushions and liners help compensate for minor mismatches.
Heavy runs need closer hanger spacing and stronger clamps. Metal supports and beam clamps with locking units are better for long horizontal runs. When in doubt, follow manufacturer spacing recommendations — they’re usually conservative for a reason.
Most suppliers sell clips and clamps in packs of 25, 50 or 100. If you’re doing a small refit, the larger pack often works out cheaper per unit and saves another trip. Tradespeople almost always buy in bulk for this reason.
If your pipe is insulated, the clip needs to accommodate that extra thickness. Some clips are designed for insulated pipe; others use spacer rings. Factor insulation into your diameter measurements.
For mains water supplies and primary heating loops, I prefer trade-grade brands such as Walraven or comparable manufacturers. They cost slightly more but come with technical specs and proven load ratings, which makes installations safer and easier to certify.
Installation doesn’t have to be nerve-wracking. With a checklist you can keep control, avoid common mistakes, and speed up the job.
Have the right tools: a spirit level, tape measure (in inches), drill with masonry bits, wrench set, and the correct anchors for your substrate. Measure twice, mark once — it’s the oldest trick but still the best. Test-fit one clip before you start drilling a run of holes.
Follow the manufacturer’s spacing guidance for pipe hangers; if unavailable, err on the side of closer spacing. For horizontal runs, install supports at regular intervals and at every change of direction. Use locking nuts or lock washers where movement could loosen fixings over time.
Work with isolation valves closed when cutting or joining live pipework. Keep runs accessible for future maintenance — hidden fixes are harder to repair and more expensive later. If you’re in any doubt about pressurised systems, call a qualified plumber rather than improvise.
How much should fittings cost? Small clips are cheap individually but add up in packs; high-quality beam clamps and proprietary PRV kits carry a premium. My approach: spend on things that need reliability—valves, heavy-duty supports—and save on items that are easy to replace, like simple plastic clips. Buying packs is almost always better value, and trade accounts can reduce costs if you plan several projects.
Choosing the right fittings can reduce water waste and energy use. A correctly set pressure-reducing valve can cut water flow and lower strain on tanks and hot-water systems, saving energy. Likewise, picking durable metal clamps reduces waste by avoiding repeated replacements. If you’re renovating, think long term — a slightly higher upfront cost often pays back in durability and fewer call-outs.
You don’t need to learn the hard way. Avoid these common errors: buying the wrong diameter clip, skimping on support spacing, using non-rated clamps for heavy loads, and installing PRVs without checking the required downstream pressure. A small error made during installation can mean a lot of rework later.
Buying plumbing fittings and supports is a balance between cost, quality, and convenience. If you value specialist items like Walraven Britclips, beam clamps with locking units, or pressure-reducing valve kits, trade suppliers and specialist electrical outlets like Expert Electrical are great places to look. For fast access or weekend fixes, Screwfix, Toolstation and high-street DIY chains cover most needs. Match the fitting to the job, measure carefully in inches, and think long-term — your future self will thank you when the pipes remain quiet and leak-free.
Whether you’re a seasoned pro or a weekend warrior, the right retail choice and correct fitting selection make the job smoother and longer-lasting. Ready to tackle that piping run? Arm yourself with the right clips, clamps and valves and the job becomes far less of a headache.
