Compare commercial insurance quotes in London
London businesses face specific risks - high-value leases, professional indemnity exposure, dense supply chains, and a competitive employment market - that standard insurance packages rarely reflect well. RFXapp collects quotes from brokers and standardises the cover, limits, and exclusions side by side so you can compare what you are actually buying.
If you are looking for the best brokers in London, the most reliable shortlist is one built around your own requirements and tested with a structured brief - not a generic ranked list. RFXapp helps you find and collect quotes from the right suppliers, and analyse them so you can compare what they actually offer, not just the headline price.
What to consider before you go to market
Getting comparable quotes starts with a well-scoped brief. These are the things most businesses overlook until they're already in the process.
Which covers are legally required and which are genuinely needed
Employers' liability insurance (minimum £5 million) is a legal requirement for any UK business with employees. Beyond that, the covers you need depend on your specific risk profile. Public liability is standard for any business with clients or suppliers on site. Professional indemnity is essential for any business giving advice or producing work a client relies on. Cyber insurance is increasingly relevant for businesses handling personal data. Before going to market, list the covers you know you need and the ones you are less certain about - a good broker will challenge both lists.
Policy exclusions - the clauses that define what is not covered
Insurance policies are defined as much by their exclusions as by their cover. Professional indemnity policies commonly exclude known circumstances, prior acts without a retroactive date, claims arising from contractual liability the insurer was not told about, and certain client sectors. Cyber policies frequently exclude human error and social engineering. Understanding the exclusions before you buy is the difference between insurance that works when you need it and insurance that does not. Ask each broker to walk you through the key exclusions for your specific situation.
Whether your indemnity limits reflect actual exposure
Many London businesses carry professional indemnity limits based on what they have always bought rather than what they actually need. The right limit depends on the size of contracts you work on, the potential financial impact of a claim, and what your clients require. A marketing agency working on a £500,000 campaign for a client carries different exposure than one working on £10,000 projects. If a claim against you could exceed your current limits, the excess is your problem. Ask each broker to help you assess whether your current limits are appropriate.
Business interruption cover and the London cost base
Business interruption insurance covers lost income and fixed costs if an insured event prevents you from trading. In London, where office rents, salaries, and fixed costs are high relative to the rest of the UK, the cost of a prolonged interruption is significant. Many businesses carry limits that would cover interruption costs for 6 months when their actual recovery time could be 12-18 months. The indemnity period - the maximum time covered - should reflect how long it would realistically take to restore full trading capacity, not an arbitrary figure from a previous renewal.
Broker panel access and independence
Insurance brokers range from genuinely independent intermediaries with access to the full market (including Lloyd's of London syndicates) to appointed representatives who can only place business with a limited panel of insurers. London has a particularly deep insurance market - Lloyd's and the London market specialty underwriters can provide cover for risks that standard insurers will not touch. Understand whether your broker is accessing the full market on your behalf or is constrained by a panel arrangement.
Claims handling - who does what and how long it takes
A policy is only as good as the claims process behind it. Some brokers act as advocates on your behalf when a claim arises. Others hand you directly to the insurer's claims team and step back. The difference matters significantly when a claim is disputed or takes months to resolve. Ask each broker to describe specifically what they do when one of their clients makes a claim - not what the insurer does, but what the broker does.
Insurance gaps that only appear when you make a claim
These are the cover gaps and contract terms that look fine during renewal but cost London businesses significantly when something actually goes wrong.
Exclusions that invalidate cover at the point of a claim
The most expensive insurance gaps are discovered after a claim has been made. Common examples in London professional services businesses: a PI policy that excludes advice given under a contract where liability was not capped (common in standard client agreements), a cyber policy that excludes social engineering fraud (the most common form of cyber loss), and a public liability policy that excludes work done at client premises (where most professional services work actually takes place). Ask your broker to review your standard client contracts and working practices against the policy wording before you buy - not after.
Auto-renewal at significantly higher premiums
The insurance market in London has hardened considerably in recent years, with PI and cyber premiums rising 20-40% year on year in some sectors. Brokers earn a percentage of your premium, which means they have a structural incentive to renew rather than re-market your policy. Many businesses discover only when they run a competitive process that their renewal premium is materially above what the market would offer for the same or better cover. Running a broker tender every two years - not just at renewal - is the only way to know whether you are being well-served.
Underinsurance on contents and equipment
Contents policies are often set at a round number chosen years ago and not reviewed since. For London offices with high-value AV equipment, laptops, specialist machinery, or stock, the cost of replacing everything in the event of a fire or flood is likely higher than the declared value. Insurers can apply average clauses - reducing any claim proportionally by the degree of underinsurance - which means a 50% underinsured policy pays out 50 pence in the pound even on a legitimate total loss claim. Do a current replacement cost estimate before your next renewal, not what you paid for the equipment, but what it would cost to replace it today.
Questions that separate good brokers from great ones
Asking is only half the job. Below each question is what a good answer sounds like, and what should give you pause. Questions marked * are mainly relevant for businesses with more complex risk profiles - professional services, regulated sectors, or significant client IP exposure.
Good answer: A specific description of the broker's role: logging the claim, appointing a loss adjuster if needed, advocating with the insurer, keeping you updated on timeline, and not considering their job done until the claim is settled. A named person who handles claims is a good sign.
Red flag: "The insurer handles claims directly" or a vague answer about "supporting you through the process." If the broker disappears when a claim arises, their value is purely at renewal.
Good answer: Specific, experience-based examples that are genuinely relevant to your type of business - not generic statements about not meeting deadlines. For a professional services firm in London, good answers might include PI claims arising from verbal rather than written advice, or content cover invalidated because equipment was used at a client site.
Red flag: A generic answer that does not reference your specific sector or risk profile. That means the broker is not thinking about your situation.
Good answer: Clear confirmation of whether they are independent or appointed representatives, which market segments they can access, and - if relevant to your situation - which Lloyd's syndicates they work with.
Red flag: A vague answer about "access to leading insurers" without specifying whether that includes the London market. Panel-restricted brokers rarely volunteer this information.
Good answer: Yes, either as part of their standard process or offered as a specific service. They can name the clauses they typically look for - unlimited liability, consequential loss, IP warranties - and explain how they interact with the policy.
Red flag: "That's a question for your solicitor" without any broker involvement. Contract review is not legal advice - it is part of understanding the risk they are insuring.
Good answer: A clear description of their remarketing process, ideally with examples of when they have moved clients to a different insurer because the incumbent was no longer competitive. Willingness to show you the quotes they received from other markets.
Red flag: "We have strong relationships with our insurer partners" without any description of how they test the market. Strong relationships with insurers can mean lower premiums. It can also mean the broker prefers an easy renewal to a competitive one.
Good answer: A specific list of trigger events that require notification (headcount thresholds, revenue growth, new services, new geographies), a clear process for notifying the broker, and confirmation that they will review the cover at each trigger event rather than leaving it to the client.
Red flag: "Just let us know if anything changes" with no further structure. Most clients do not know what changes are material, and a broker who does not proactively manage this is leaving you exposed.
Where you have more negotiating room than you think
Insurance brokers have more room to move on price and terms than a renewal quote suggests. These are the levers that work once you are comparing competing proposals.
Bundle policies with one broker
Placing all your commercial insurance - public liability, employers' liability, professional indemnity, cyber, contents - with a single broker typically produces a better premium than placing each policy separately. Brokers value the consolidated relationship and can often negotiate a package discount with the insurer. The trade-off is concentration risk: if the relationship goes wrong, all your renewals are affected at once. Ask each broker to quote both bundled and individual to see the actual discount.
Annual payment instead of monthly
Monthly premium payments attract a finance charge from the insurer - effectively an interest rate of 8-15% on the annual premium. Paying annually eliminates this. For a business paying £12,000/year in premiums, switching from monthly to annual saves £1,000-£1,800 in financing costs. If cash flow allows it, this is the easiest saving available at renewal.
Run a genuine broker tender
Most businesses use the same broker for years without testing the market. Running a structured tender - two or three brokers quoting against the same risk schedule - routinely produces materially better premiums than a renewal from the incumbent. The incumbent often drops their renewal quote when they know they are competing. If they do not, you have real alternatives. This is the single most reliable way to improve your insurance costs.
Negotiate the excess before you compare premiums
Excess levels (the amount you pay before the insurer contributes) are often set at a default that suits the insurer rather than one that suits your risk appetite. A higher excess reduces the premium - sometimes significantly on PI and cyber policies. A lower excess increases it. Before comparing premiums between brokers, agree the excess level you want and ask all brokers to quote on the same basis. Otherwise you may be comparing a low-excess quote with a high-excess one without realising it.
Claims-free record
A clean claims history is a material factor in commercial insurance pricing. If you have not made a claim in three or more years, say so explicitly when going to market - do not leave it to brokers to discover during underwriting. Some brokers will use this proactively to negotiate a discount. Others will not unless you ask. Your claims history belongs to you and you should understand its value.
Risk management improvements for better terms
Insurers offer better premiums to businesses that can demonstrate they actively manage their risks. For cyber insurance, this means showing MFA is in place, that staff receive phishing training, and that backups are tested. For PI, it might mean documented project management and sign-off processes. Ask each broker what risk management improvements would produce a meaningful premium reduction - and then implement the ones that make sense regardless of the insurance benefit.
