Getting three quotes for an electric gate installation in London and ending up with prices ranging from £3,500 to £12,000 for what sounds like the same job is a common experience. The range is not random and it is not all down to different profit margins. It reflects genuine differences in what is being quoted, what is being left out, and what quality of product and installation each number represents.
This guide explains why gate quotes vary so dramatically, what information you should have ready before asking for quotes, what a complete and honest quote must include, and the specific questions that reveal the difference between a thorough installer and one who is competing purely on a headline price.
Why Electric Gate Quotes Vary So Much
The short answer is that different installers are often quoting genuinely different products and scopes of work, and the buyer has no way of knowing this from the headline numbers alone.
Bespoke fabrication versus catalogue supply. A gate fabricated to the specific dimensions of your entrance, in the design and finish you have specified, costs more than a standard-size gate taken from a catalogue and adapted to fit. On a London period property with non-standard pier spacing, the catalogue gate is almost always the wrong specification regardless of the price saving. An installer quoting a bespoke fabricated gate and an installer quoting a standard-size supplied gate are not quoting the same product.
What is included in the scope. Some quotes include the gate, motor, intercom, groundworks, electrical connection, and commissioning as a single complete price. Others quote only the gate and motor supply and add everything else as separate line items that the buyer discovers later. A quote that looks £2,000 cheaper may have excluded the electrical cabling from the consumer unit to the gate post, the groundworks for the post foundations, and the safety device commissioning and documentation. Once those are added, it is no longer cheaper.
Motor quality and specification. Motor systems range from budget units with a two or three-year operational life under heavy use to quality CAME residential motors rated for 100,000 cycles with a five-year manufacturer warranty. The cost difference between a budget motor and a quality motor in a supply-only sense is typically £200 to £400. The cost difference over a five-year ownership period, once earlier replacement and callout visits are factored in, is considerably higher.
Whether safety compliance is included. Under HSE guidelines for powered gate installations, all electric gates require safety photocells, safety edges, and a force compliance test at handover. These are not optional extras. An installer who excludes them from the quoted scope is cutting costs in a way that leaves you with a gate that is not legally compliant and potentially dangerous. Some budget quotes omit safety devices entirely and expect the buyer not to notice.
Site-specific groundwork. A gate installation on a flat driveway with easy cable access from the house is a simpler job than one on a sloped site with a long cable run under an established path and London clay foundations that need to go to 700mm depth. Both jobs might be described as “standard residential electric gate installation” in a quote but the cost difference on site is real.
What to Prepare Before Asking for Quotes
Having this information ready when you contact installers produces better quotes faster and makes comparisons more meaningful.
Opening width. Measure the clear width between the inner faces of the gate posts or the boundary wall at the entrance. Take the measurement at three heights, at the ground, at mid-height, and at the top of the opening, because Victorian and Edwardian piers are not always perfectly plumb and the opening width can vary. Note the narrowest measurement as the controlling dimension for the gate fabrication.
Driveway depth. Measure from the gate line (the face of the boundary wall or post) straight back to the nearest obstacle: the house wall, the front of a parked car, or any step or change in level. This determines whether swing gates are viable. See our sloped driveway guide if the driveway also has a significant gradient.
Wall space for a sliding gate. If a sliding gate is a possibility, measure the run of clear wall or fencing alongside the entrance on each side. The longer run is where the gate would slide open. If this measurement is at least equal to the opening width, a sliding gate is viable.
Distance from consumer unit to gate post. Walk the cable route from where the gate’s power supply would enter the house to the gate post position and estimate the distance. Include any changes in direction, under-path sections, or areas where the route crosses established hard landscaping. This is the figure that most significantly affects the electrical installation cost on London properties.
Photos. Take photographs of the entrance from the road, from inside the driveway looking out, and close-up shots of each gate post or pier from front and back. Include photographs of the boundary wall character, any surviving ironwork, and the route the cable would likely take from the house to the gate. Sending good photos with your enquiry produces better initial estimates and reduces the number of things that need to be clarified at the site visit.
Planning and conservation area status. Check whether your property is in a conservation area and whether you know of any Article 4 Directions that affect boundary changes on your street. If you are not sure, your local planning authority can confirm. See our conservation area guide for the full framework. If the property is listed, listed building consent is required before work begins regardless of gate size or type.
What a Complete Quote Must Include
A written quote for a residential electric gate installation in London should break down the following items separately. If any of these are absent or described vaguely, ask specifically about them before comparing prices.
Gate supply and fabrication. The gate itself: material, dimensions, design specification, and whether it is fabricated to your specific measurements or supplied from a standard size range. For period London properties, the specification should name the infill bar section, the finial type, the top rail profile, and the finish colour by RAL reference.
Motor system. The motor manufacturer and model, the motor type (articulated arm, underground, ram arm), and the rated duty cycle. For a residential gate used six to ten times a day, the motor should be rated for at least 100,000 cycles. The gate board and any battery backup should also be specified by manufacturer and model.
Access control and intercom. The intercom type (audio only, video, GSM/app-integrated), the manufacturer and model, and whether the installation includes programming and demonstration. If smart gate app integration is included, confirm which app and which GSM module.
Electrical installation. The route and method of cable installation from the consumer unit to the gate post, including any trenching required, depth of burial, conduit type, and surface reinstatement. This item has the widest variation in cost across London properties and is the most commonly vague line in budget quotes.
Groundworks and post foundations. Whether new gate posts are included or existing piers are being used, the foundation depth and specification for the specific ground conditions on site, and any reinstatement of surface materials disturbed during groundwork.
Safety devices. Photocells and safety edges should be explicitly listed as included items, not implied. The quote should state that EN 12453 force compliance testing and documentation will be provided at handover.
Warranty terms. The structural warranty on the fabricated gate and the warranty on the motor system should both be stated. A quality gate fabricator will provide a minimum of five years on the steelwork and the motor manufacturer will typically provide two to five years depending on the product. At NOVA Gates & Railings, all fabricated steelwork carries a 10-year structural warranty.
What is excluded. Any complete quote should state what is not included: planning application fees, conservation area consent costs, making good any decorative surface damaged during installation, or any work by trades other than the gate installer.
The Questions That Separate Good Installers from Poor Ones
These questions take less than ten minutes to ask and the answers reveal a great deal about the quality and honesty of the company you are talking to.
Where is the gate fabricated? An installer who fabricates in-house has direct control over every dimension and specification of the gate. An installer who supplies from a catalogue or third-party manufacturer has less control and less accountability if the gate does not match what was agreed. In-house fabrication is not the only valid model, but an installer who cannot tell you clearly where the gate is made is not giving you complete information.
Is the gate fabricated to my specific measurements or is it a standard size? For London period properties with non-standard pier spacings, the answer to this question determines whether the installation will look correct. A gate fabricated to the measured opening sits properly in the entrance. A standard-size gate that has been adapted to fit leaves visible compromises.
Does the quote include safety devices and EN 12453 force compliance documentation? A competent installer will not hesitate on this question. If the answer is vague or the installer needs to check, that is a clear signal.
Have you assessed the planning position for this property? In a borough like Merton, Wandsworth, Richmond, or RBKC, a gate installer who has not raised the conservation area and Article 4 Direction question during the survey is not giving you complete advice. See our planning permission guide for what applies across London and Surrey.
What motor brand and model is being specified? CAME, BFT, FAAC, and NICE are the main quality motor brands used by professional installers in the UK. A quote that names only “electric motor” or “automation system” without naming the manufacturer is not giving you enough information to assess the quality of what you are buying.
What is the electrical installation included in the quote? This is where budget quotes most often hide costs. Ask specifically: is trenching under the path included? What depth will the cable be buried? Is surface reinstatement included if the path needs to be lifted?
Can I see examples of comparable installations in London? A quality installer working regularly in South West London and Surrey will have a portfolio of completed projects in the area. If an installer cannot show you completed work on period London properties similar to yours, that matters for a conservation area installation where period-sympathetic design is essential.
How to Compare Quotes Properly
Once you have written quotes from two or three installers, comparison on price alone is almost never the right approach. The following process produces a more useful comparison.
Strip the quotes back to the same scope. Identify any items that are included in one quote but not another and add them as separate estimates to the quote that excludes them. You are trying to get to a total delivered cost for the same complete installation, not a comparison of headline numbers that represent different scopes.
Assess the gate specification, not just the price. Two quotes for “electric swing gates for a 3.5-metre opening” may be quoting a catalogue standard gate and a bespoke fabricated gate to your specific pier spacing. These are not the same product and should not be compared on price as if they are.
Check the motor specification against the duty cycle. If one quote specifies a CAME BX608 and another specifies an unnamed motor, the named motor has a published specification that can be assessed. The unnamed motor cannot.
Factor in the warranty terms. A 10-year structural warranty on fabricated steelwork is meaningfully different from a two-year warranty. The longer warranty signals confidence in the fabrication quality and reduces your risk exposure over the ownership period.
Consider the planning competence. If your property is in a conservation area or has any planning complexity, the installer’s knowledge of and approach to that complexity matters as much as the gate price. An installer who gets the planning wrong, or who installs without flagging a planning requirement that then needs to be retrospectively addressed, adds cost and stress that was not in any quote.
