Spirit Levels

About Spirit Levels

Spirit levels are essential precision tools that enable tradespeople and DIY enthusiasts to achieve perfectly horizontal and vertical surfaces across construction, installation and maintenance projects. Also known as bubble levels, these indispensable measuring instruments use sealed vials containing liquid and an air bubble to indicate when a surface is perfectly level or plumb. MyToolShed.co.uk stocks a comprehensive range from compact torpedo levels that fit in toolbags to professional-grade models extending beyond two metres, featuring trusted brands including Stabila, Bahco, Hultafors, DeWalt, Milwaukee, Bosch, Facom, Draper and Faithfull.

Modern spirit levels have evolved significantly, now incorporating features such as magnetic bases for hands-free use on metalwork, reinforced box beam frames for site durability, integrated laser technology, and LED lighting with audio alerts for working in challenging conditions. Professional-grade models feature milled surfaces for exceptional accuracy (typically 0.5mm/m or better), whilst budget-friendly options provide reliable performance for occasional domestic use.

Applications

Spirit levels are used daily across numerous trades and applications:

• Bricklayers and Stonemasons: Ensuring courses are level and walls are plumb during construction work
• Carpenters and Joiners: Installing door frames, window reveals, skirting boards, kitchen units and fitted furniture
• Plumbers: Achieving correct fall on waste pipes and levelling radiators, sinks and bathroom fixtures
• Electricians: Positioning consumer units, mounting sockets and switches at consistent heights
• Tilers: Ensuring tile courses remain level and maintaining vertical alignment throughout installations
• Landscapers: Creating level patios, checking retaining walls and establishing proper drainage gradients
• Kitchen and Bathroom Fitters: Installing worktops, wall units and sanitaryware to precise tolerances
• DIY Enthusiasts: Home improvement projects from shelving installation to garden decking

Choosing The Right Spirit Levels

Length Considerations: Select the longest level your typical work accommodates. A 600mm level suits general carpentry, whilst 1200-1800mm models are ideal for larger joinery and building work. Keep a compact torpedo level for tight spaces.

Accuracy Requirements: Professional tradespeople should invest in levels with accuracy ratings of 0.5mm/m or better. DIY users undertaking occasional projects may find 1.0mm/m adequate for general tasks.

Construction Quality: Box beam aluminium levels offer superior rigidity and durability for demanding site work, resisting knocks and drops common on busy building sites. Lighter I-beam or plastic levels suit less intensive domestic applications.

Specialist Features: Magnetic bases are invaluable for steelwork and metal frame construction. Digital inclinometers provide precise angle measurements, whilst integrated laser levels project reference lines across surfaces.

Budget Considerations: MyToolShed.co.uk offers entry-level models from Draper and Faithfull for light DIY use, mid-range options from Bahco, Hultafors and Facom for serious enthusiasts, and premium models from DeWalt, Milwaukee and Bosch for professional use.

Frequently Asked Questions

How accurate are spirit levels and do they need calibrating?

Professional spirit levels typically offer accuracy between 0.5-1.0mm per metre when new. Test accuracy by placing your level on a flat surface, noting the bubble position, then rotating it 180 degrees on the same spot. The bubble should read identically. Most professional models cannot be recalibrated, so protecting your investment with proper storage is essential.

What length spirit level do I need?

This depends on your typical applications. A 600mm level handles most general carpentry and domestic tasks. For kitchen fitting and serious DIY work, a 1200mm level is more versatile. Professional builders often carry multiple lengths (600mm, 1200mm and 1800-2400mm) to suit different situations.

What's the difference between budget and professional spirit levels?

Professional levels feature milled working surfaces for perfect flatness, robust box beam construction, superior vial quality, and better accuracy ratings (0.5mm/m versus 1.0-2.0mm/m). They're built for daily site use and last decades, whilst budget levels suit occasional DIY use but may not withstand professional conditions.
