Install a garden gate.

Whether you are replacing a rotten side gate or installing a grand entrance to your driveway, professional installation ensures the posts remain plumb and the latch aligns perfectly year-round. This guide covers everything from material choices to the latest UK pricing for 2025/26.

What Does the Work Involve?

• Site Survey: Measuring the opening accurately and checking for underground services or drainage issues before digging.
• Old Gate Removal: Dismantling the existing structure and disposing of old timber, metalwork, and concrete footings.
• Post Installation: Setting new timber or metal posts into the ground using fast-setting concrete (Postcrete) or bolting to existing masonry.
• Hanging the Gate: Attaching heavy-duty galvanised hinges and ensuring the gate is level with the correct "fall" for drainage.
• Ironmongery Fitting: Installing latches, bolts, and gate-stops to ensure the gate stays closed and doesn't slam in high winds.
• Final Adjustments: Planing the bottom edge for ground clearance and applying wood preservative to any fresh cuts.

Typical Costs

The cost of garden gate installation varies significantly based on the material chosen and whether new posts are required. Standard softwood gates are the most budget-friendly, while bespoke hardwood or metal options sit at the higher end of the scale.

Prices generally include VAT. Factors such as working on a steep slope, drilling into reinforced concrete, or requiring bespoke joinery will push costs toward the higher end of these estimates.

How Long Does It Take?

• Like-for-like swap: 2–3 hours if the existing posts are sturdy and plumb.
• New post installation: 4–6 hours, allowing time for the concrete to initial-set before hanging the gate.
• Double driveway gates: 1 full day, including post-setting and precise alignment of the meeting stiles.
• Masonry fixings: Add 1 hour if wall plates need to be chemically anchored into old or crumbly brickwork.

DIY or Professional?

A simple "off-the-shelf" gate swap is a manageable DIY task for those with basic carpentry tools. However, installing new posts is physically demanding and requires precision; if the posts are even slightly out of alignment, the gate will never close properly.

Professional installers have the heavy-duty SDS drills and augers required to bypass stones or old foundations that often thwart DIY attempts.

For automated gates or those involving integrated intercoms, you must hire a professional. Any electrical work must comply with Part P of the Building Regulations and be signed off by a competent person.

Choosing the Right Tradesperson

• Check Specialisms: Look for a fencing contractor or a specialist joiner rather than a general "handyman" for high-end hardwood gates.
• Insurance: Ensure they hold Public Liability Insurance (minimum £1 million) to cover accidental damage to your property.
• Timber Quality: Ask if they use UC4-rated timber for posts, which is specifically treated for ground contact.
• Waste Licence: Confirm they are a registered waste carrier if they are taking the old gate away.

Questions to ask:

• "Will the gate be hung with a gap for expansion during winter?"
• "Do you include a gate-stop to prevent the hinges from being strained in the wind?"
• "Is the ironmongery galvanised to prevent rust streaks on the wood?"

UK Regulations

• Planning Permission: Generally not needed if the gate is under 2 metres high. However, if it is adjacent to a highway used by vehicles, the limit is usually 1 metre.
• Conservation Areas: If you live in a Conservation Area or a Listed Building, you may need consent to change the style or material of your gate.
• Waste Transfer Note: If a professional removes your old gate, they should provide a note proving it was disposed of at a legal commercial site.
• Part M: For new builds or major renovations, gates should ideally provide a clear opening width of 850mm for wheelchair access.

Common Problems

• Gate Sagging: Usually caused by using hinges that are too light for the weight of the timber. Always use "hook and band" hinges for heavy gates.
• Post Rot: Occurs when posts are "encased" in concrete without drainage. A professional will ensure the concrete creates a shed-slope away from the timber.
• Seasonal Swelling: Timber expands in the damp UK winter. If fitted too tightly in summer, the gate will bind and refuse to close by November.
• Latch Misalignment: As the ground settles or the wood moves, latches can drift. Using adjustable hinges allows for easy recalibration.
