Choosing a gate installer in London is a decision that will affect your property for the next fifteen to twenty years. The gate and motor system you end up with reflects the quality of the company that specified, fabricated, and installed it. The widest price variation in any home improvement market in London is in electric gate installation, from under £3,000 to over £15,000 for what sounds like the same job. The variation exists because the products and the scopes of work are genuinely different.
This guide gives you the questions to ask any installer, including NOVA Gates & Railings, and the red flags that reveal an installer who is competing on price rather than on quality. It is written with the same honesty we bring to a site survey: useful to you regardless of which company you choose.
The Landscape of Gate Installers in London
London’s gate installation market is broadly split into four types of company.
Bespoke fabricators. Companies that design and fabricate gates in-house to the specific measurements of each entrance. Every gate is made for the property it goes on. Lead times are longer and costs are higher, but the result fits the entrance correctly, responds to the property’s architectural character, and has no compromises forced by standard sizes.
Supply and install companies. Companies that source gates from a manufacturer or catalogue and install them. Gates are adapted to fit the opening rather than fabricated for it. Faster and usually cheaper. Appropriate for standard openings on contemporary properties. Less appropriate for period properties with non-standard pier spacings or conservation area requirements.
General contractors. Fencing, landscaping, or construction companies that include gate installation in their offer. Variable quality and variable knowledge of the safety compliance requirements. Often the source of installations that lack proper documentation.
National companies. Larger companies operating across the UK with local installation teams. Variable quality depending on the specific local team. Useful for standard residential installations with straightforward briefs.
For a period London property in a conservation area, a bespoke fabricator is almost always the right choice. For a contemporary new-build with a standard brief, a good supply and install company can produce an excellent result.
10 Questions to Ask Every Gate Installer in London
1. Where is the gate fabricated and by whom?
The most important question you can ask. An installer who fabricates in-house has direct control over every dimension and every weld. An installer who sources from a third-party supplier has less accountability for fit, finish, and the accuracy of the measurements used.
For a London period property with original brick piers at a non-standard spacing, a gate fabricated to the measured opening is the only way to get a gate that closes correctly without visible gaps or forced adjustments.
2. Is the gate fabricated to my specific measurements or is it a standard size?
Related to the above but more direct. A yes or no answer. If the gate is a standard size from a range, ask what the nearest standard is to your opening width and what the adaptation process involves. On a 2,850mm opening, a 2,800mm catalogue gate leaves a 50mm gap at the closing post that is visible from the street.
3. Does the quote include safety devices and EN 12453 force compliance documentation?
A professional installer will answer this without hesitation. Safety photocells, safety edges, force testing, and a Declaration of Conformity are legal requirements under the Supply of Machinery (Safety) Regulations 2008, not optional extras. If the answer is vague, or the installer needs to check, that tells you everything you need to know about their compliance knowledge.
See our electric gate safety guide for the full legal framework.
4. What motor brand and model is being specified and why?
CAME, BFT, FAAC, and NICE are the four main quality motor brands used by professional installers in the UK. A quote that says “automation system” or “electric motor” without naming the manufacturer is not giving you enough information to assess what you are buying. Ask specifically which model, what the duty cycle rating is, and what the manufacturer warranty covers.
5. Is the electrical installation included in the quote?
This is the line item that varies most dramatically between quotes. Ask specifically: is trenching under the path included? What depth will the cable be buried? Is surface reinstatement included if hard landscaping needs to be lifted? What is the assumed cable run length and what happens if it is longer? On some London properties the electrical installation can add £800 to £1,500 to the cost and a budget quote that excludes it is not the price you will pay.
6. Have you assessed the planning position for this address?
In a borough with significant conservation area coverage, including Merton, Wandsworth, Richmond, and RBKC, an installer who has not raised the planning question during the survey is not giving you complete advice. The planning position needs to be confirmed before fabrication begins. See our planning permission guide and conservation area guide for the framework.
7. What does the warranty cover and for how long?
The structural warranty on the fabricated gate and the motor warranty should both be stated in writing. A quality gate fabricator provides a minimum of five years on the steelwork. NOVA Gates & Railings provides a 10-year structural warranty on all fabricated metalwork. The motor manufacturer typically provides two to five years depending on the product.
8. Who does the electrical work?
Some installers carry their own Part P qualified electricians. Others subcontract the electrical work to a separate trade. There is nothing wrong with subcontracting if the subcontractor is qualified and their work is covered by the installer’s overall liability. What you want to avoid is an installation where the electrical work is unquantified in the quote because it is being handled informally.
9. Can I see examples of comparable installations in London?
A quality bespoke fabricator working regularly in South West London and Surrey will have a portfolio of completed work on properties similar to yours. For a Victorian terrace with original brick piers in a conservation area, ask specifically to see previous work on period properties in comparable conservation areas. An installer who cannot show you relevant local work is not the right choice for a conservation area installation.
10. What is the service and support arrangement after installation?
Ask directly: who do you contact if the gate develops a fault? What is the expected response time? Is annual servicing available and what does it cost? A gate that operates without a reliable service relationship is a problem waiting to happen. The best installers either offer their own annual service programme or have a clear referral arrangement with a qualified engineer.
Red Flags to Watch For
A quote given without a site visit. No gate installation can be accurately quoted without a site visit. An installer who quotes from photos or over the phone is making assumptions about ground conditions, cable route, gate geometry, and planning position that will either cause problems during installation or be corrected by additional charges.
Safety devices described as optional or as an upgrade. Photocells and safety edges are legal requirements under the HSE’s powered gate guidelines, not an optional add-on. Any installer who presents them as optional is either not aware of the compliance requirements or is deliberately excluding them to reduce the headline price.
No planning or conservation area question raised. In most of South West London and Surrey, the planning position for a gate installation is worth confirming before fabrication begins. An installer who does not raise this question at the survey stage is not giving you complete advice.
Vague motor specification. “Quality automation” or “European motor” with no manufacturer name or model number. You are entitled to know exactly what motor system is being installed. If the installer will not or cannot tell you, the specification is likely to be a low-cost import rather than a quality branded system.
Pressure to decide immediately or to accept a deposit before a written quote is provided. A professional installer provides a written itemised quote, gives you time to consider it, and does not pressure you to commit before you have read and understood what you are agreeing to.
No examples of local comparable work. For a period London property, particularly in a conservation area, an installer who cannot show you completed work on similar properties in similar contexts does not have the specific experience your project requires.

Frequently Asked Questions
What should I look for in an electric gate installer in London?
In-house fabrication, CAME or equivalent certification, proven London period property experience, a site visit before any quote, and full EN 12453 safety compliance documentation at handover. These five things separate a quality installer from a poor one.
Do gate installers need to be certified?
There is no mandatory UK licensing for gate installers, but CAME approved status and DHF training are the recognised professional standards. These cover the safety compliance training that the work requires under the Supply of Machinery (Safety) Regulations 2008.
Should I get multiple quotes for electric gates?
Yes, two to three quotes from different companies. But comparing on price alone without comparing scope and specification will mislead you. See our electric gate quote guide for how to compare properly.
What is a red flag when getting an electric gate quote?
A quote given without a site visit, a price that excludes safety devices or commissioning, no mention of EN 12453 compliance documentation, and an installer who cannot tell you where the gate is fabricated.
How long should a quality electric gate installation last?
A quality gate with proper specification and annual servicing should last 15 to 25 years on the steelwork, with motor replacement around year 10 to 15.
