If you are budgeting for custom garden trellis at your home in Sible Hedingham, here is an honest guide to what the work typically costs and what drives the price up or down.
When you get a quote for custom garden trellis, the price reflects more than just the timber. It covers the survey visit, the design and cut of the panels to your exact measurements, any preparatory work on the fixing points, the fitting itself, and the clean-up. A quote that seems unusually low is usually missing one or more of those elements.
Haverhill Fencers builds and fits custom trellis panels to order. The figures below are honest typical ranges for the UK market. Your specific job may fall above or below them depending on the factors set out in this page.
As a broad guide, custom softwood trellis panels including fitting typically cost in the region of £80 to £200 per panel for straightforward fence-topper or wall-mounted work. A full fence run of four to six panels with standard square or diamond lattice, fitted onto existing posts in reasonable condition, would commonly come out at £400 to £900 in total.
Hardwood trellis (oak or iroko) in equivalent sizes will add roughly 60 to 80 per cent to the timber element of the cost. A single hardwood panel in custom dimensions can reach £200 to £350 or more before fitting, depending on the section size and the species.
These are indicative ranges, not fixed-price quotes. The only accurate price for your job is one based on your actual site measurements and the specific work required.
Several factors consistently add to the final cost of a trellis installation. Understanding them helps you make informed decisions about what you want and what you can adjust.
Treated softwood at 38 mm section is the starting point. Moving to 44 mm or 50 mm section increases the cost modestly but produces a noticeably more solid-looking panel. Moving from softwood to hardwood is the single largest cost jump in the material. For a visible garden feature where the quality of the timber matters to you, hardwood is worth considering. For a functional screen or climber support that will be largely covered in foliage, treated softwood does the job well at a lower price.
Larger panels cost more to make and are heavier to handle on site, which adds time. Shaped tops (arched, stepped, or pointed) require additional cutting and checking. Corner sections that mitre at 90 degrees take longer to fit accurately. None of these additions are prohibitively expensive, but each one adds something to the total.
If the fence posts that the trellis will sit on top of are in sound condition, the fitting is straightforward. If a post is soft at the base, leaning, or cracked through, it needs attention before the trellis goes up. Post repairs or replacements are priced separately from the trellis panels themselves, but they are not optional if the post is genuinely failing. A trellis fitted to a rotten post will come down with it.
Fitting trellis to a brick or block wall takes longer than fitting to a timber post because each anchor point requires drilling, plugging, and correct spacing from the wall surface. A run of masonry wall that needs six or eight anchor points per panel will add time compared to the equivalent post-mounted job. The fixings themselves are also more expensive than timber screws.
Where the boundary runs behind a shed, alongside a greenhouse, or in a narrow side passage, working space is reduced and fitting takes longer. If scaffolding or steps are needed for a high wall, that adds to the day rate.
Bare pressure-treated timber is included in the panel price. If you want a painted or stained finish applied before and after fitting, that adds to the cost but is worth doing if you want a particular colour or a cleaner look from day one. Spirit-based stain is typically less expensive to apply than a full painted finish because it needs fewer coats and dries faster.
The most effective way to reduce the cost of a custom trellis job is to make sure the existing fence posts and wall fixings are in good enough condition to use. If the posts are sound, the job is simpler. Choosing treated softwood over hardwood, a standard square lattice pattern over a more elaborate design, and a plain sawn finish over a painted one will all keep the price closer to the lower end of the range.
Combining trellis installation with other fencing work at the same time also tends to be more cost-effective than two separate visits. If you are already having fence panels replaced or a gate fitted, adding trellis toppers to the same job uses the same setup time.
Online price calculators and ballpark figures can give you a starting point, but the only useful quote for trellis work is one based on a visit to your specific property. A 10-metre fence run with sound posts on level ground is a different job to a 10-metre run with two failing posts, a slope, and a gate to work around.
When you receive a quote, it should set out clearly what is included: the number of panels, the timber specification, the pattern, any finish, and the scope of any preparatory work. If a quote does not distinguish between the panel cost and the fitting cost, ask for that breakdown. It makes it easier to compare quotes from different contractors on a like-for-like basis.
In most cases, garden trellis fitted on top of an existing fence does not require planning permission, provided the total height of the fence plus trellis does not exceed 2 metres on a boundary that does not face a highway. If the boundary faces a road, the permitted height drops to 1 metre. These are the standard permitted development rules in England, but they can be affected by conditions attached to your property or by being in a conservation area. If you are in any doubt, it is worth checking with your local planning authority before the work is done. We can advise on typical situations but cannot make a planning determination on your behalf.
On shared boundaries, it is always sensible to let your neighbour know before fitting trellis that changes the appearance of the fence, even if permission is not legally required.
