Commercial Pest Control: A Guide for UK Businesses

Commercial pest control is the work of keeping pests out of business premises and proving that you do. It covers inspection, proofing, monitoring, treatment where needed, and written records. It differs from a home treatment in one main way: the business has legal duties to customers, staff and inspectors, so the paperwork matters almost as much as the pest.

The direct answer is that you need a working system, and not always a contract. Annex II of Regulation 852/2004 tells food businesses that adequate procedures must be in place to control pests. It does not say who must do this or how often. The Food Standards Agency (FSA) says a business could employ a contractor, which confirms that this is a choice.

Our recommendation is simple. If you prepare, store or sell food, or you have had the same pest twice, put planned visits and written reports in place. If you run low-risk premises and have one clear problem, pay for a one-off course and then run your own checks. The rest of this guide explains why, sector by sector.

This guide covers the law as it applies in England, with a London focus. The 2013 food hygiene regulations cited here are the English ones, and the 1949 pests law does not extend to Northern Ireland, so check local rules if you trade elsewhere. It is general information and not legal advice. If you have received a notice or a court summons, speak to a solicitor who handles food law.

Six pieces of law do most of the work, and they stack. An office may meet two or three of them. A restaurant meets all of them, because it is a food business, an employer and an occupier of land at once. The table sets out who each one reaches, and the drawing shows how that plays out by premises type.

Regulation 852/2004 is EU law that stayed on the UK statute book after Brexit. It was known as retained law, and the FSA now uses the word assimilated. The wording on pests has not changed, and legislation.gov.uk shows no outstanding changes to Annex II.

The core rule takes up one short sentence in Chapter IX of Annex II: adequate procedures are to be in place to control pests. Article 4 of Regulation 852/2004 makes Annex II binding on food businesses after primary production, such as manufacturers, caterers and retailers. The Waltham Forest case below turned on exactly this wording.

The same annex touches pests in three other places. Chapter I says the layout and design of premises must allow good hygiene, including pest control. Chapter VI says refuse stores must be kept clean and, where necessary, free of animals and pests. Chapter IX also says food must be protected against contamination that would make it unfit to eat. So a business can fail on the building, the bins or the storage even if a contractor visits every month.

Food touched by pests raises a separate issue. Under Article 14 of Regulation 178/2002, food is unsafe if it is unfit for human consumption, and contamination can make it unfit. If part of a batch is unsafe, the rest is presumed unsafe too, unless a detailed assessment shows otherwise. This is why the FSA tells caterers to throw away food they think has been touched by pests, and why a gnawed carton on a pallet can cost you the pallet.

If unsafe food has already left your control, Article 19 of the same regulation requires you to start withdrawing it straight away and to tell the authorities if it could harm people. The FSA's guidance says to tell your local authority immediately.

Then there is the defence. Both section 21 of the Food Safety Act 1990 and regulation 12 of the 2013 Regulations let you show that you took all reasonable precautions and exercised all due diligence. A contract alone does not prove that. Records showing that you found a problem, acted on it and checked the result are what give the defence substance, which is why we recommend treating them as part of the pest control itself.

Outside the food sector, health and safety law does the work. Section 2 of the Health and Safety at Work etc. Act 1974 requires employers to keep the working environment safe and without risks to health, so far as is reasonably practicable. Section 3 extends the duty to people who are not employees, such as customers and contractors. Section 4 reaches anyone who has control of non-domestic premises, and treats a person with a contractual or tenancy duty to maintain them as having control of those matters.

No section mentions pests by name, so ask what a reasonable employer would do. HSE gives the clearest example: its construction guidance on Weil's disease links the risk to places where rats are or have been present. The disease is rare in the UK, but HSE says staff at risk need gloves, hand hygiene, breaks away from the work area, and waterproof dressings on cuts. If staff must clear droppings or work where rats have been, assess it first. Our guides to rat droppings and mouse droppings cover identification.

Welfare law matters too. Regulation 9 of the Workplace Regulations 1992 says workplaces must be kept sufficiently clean and that waste must not build up except in suitable containers. Regulation 25 requires suitable places to eat where food could otherwise be contaminated at work.

The 1949 Act applies to every occupier of land except agricultural land. If you know rats or mice are living on or visiting your land in substantial numbers, section 3 says you must give the council written notice straight away, and failing to do so is an offence. Section 4 lets the council serve a notice on the owner, the occupier or both, requiring treatment or structural work within a reasonable time. Under section 5, if you ignore it, the council can do the work, recover the cost and prosecute you.

Part II of the same Act is less well known. Section 13 says that if your business makes, stores, transports or sells food, and you learn of an infestation in your premises, vehicles, equipment or goods, you must give written notice to the Minister straight away. Regulations made in 1950 relax this for some insect and mite infestations. Few managers know the duty exists, so if you find an infestation in stored food, ask your council's food team or your solicitor how it applies to you.

The FSA's guidance says officers score three things: how food is handled, the physical condition of the business, and how food safety is managed. Pest control is listed under physical condition, next to cleanliness, layout, lighting and ventilation. A 5 requires doing well in all three, so a kitchen with excellent cooking habits can still lose its top rating because of a gap under a door.

Pests can also hurt the third score. Officers judge whether standards are likely to be kept up, and that is hard to believe if your diary shows a contractor's advice ignored for months. The guidance gives no separate pest score, so nobody can honestly promise what one finding will do to your rating.

In England, displaying the sticker is optional. In Wales and Northern Ireland, it is a legal requirement. That matters less than it seems, because ratings appear on the FSA's website either way. Ratings of 0 to 4 are published three to five weeks after inspection, which leaves time for an appeal.

If you disagree with a rating, or you have fixed the problem, you have four routes. Take the first that fits.

The FSA says officers can enter at any reasonable time and usually arrive unannounced, so you cannot prepare for the day itself. They look at your premises, how you work, your food safety management system and the food you make. Some premises may be inspected at least every six months and others far less often, depending on the type of business and its record. Visits can also follow a complaint, and a complaint is what led officers to the Leyton restaurant in the case below.

For pests, an officer is looking for three things: signs of activity, ways in, and evidence that you have it under control. The signs are the ones the FSA's Safer Food, Better Business pack lists for caterers. Walk your own site as an officer would, and do it with a torch.

Yes, and it can happen the same day. The FSA says officers must allow enough time for changes unless there is an immediate risk to public health. Where there is one, the steps below escalate quickly. Waltham Forest Council names a serious pest infestation as an example of an imminent risk that may require a business to close until the risk is removed.

A hygiene emergency prohibition notice works in stages. The officer gives at least one day's notice before asking magistrates for an order, and the notice lapses after three days unless an application is made. A copy must be posted in a conspicuous place on the premises as soon as practicable, where customers and neighbours can read it. The business reopens only when the council certifies that enough has been done, and the council must issue that certificate within three days of being satisfied. If you ask for a certificate, it must decide within 14 days.

The direct cost is only part of it. Each week closed means lost trade, wasted stock, staff wages and rent, and every case in the table below reached the public through a council press release naming the business. We would treat that as the larger risk, because a fine is paid once and a named news story stays searchable. These cases are as reported by each council, and they say nothing about how those sites operate today.

Pest control for restaurants deserves the most attention, because a kitchen offers warmth, water, food and hiding places in one room. All four cases in the table above involved food businesses. We recommend planned visits for any busy kitchen, and a written pest procedure inside your food safety plan even if you are small.

Mice feature in three of the four cases above, and our guide on getting rid of mice covers their habits. Treatment alone will not hold if they can get back in, so ask for rodent proofing around pipes, door bottoms and kick plates as part of the plan. Cockroaches need a different approach, because they live in the warm gaps around ovens, fridges and fryers. Read our cockroach guide before anyone reaches for a spray, then look at cockroach control for a kitchen.

Drains deserve their own line in the plan. The FSA warns against pouring fats, oil and grease down drains. If rat activity keeps returning around a kitchen, a drain and sewer camera survey can check for a defect before you spend more on bait. Flies usually point to waste or drains, so find the source first, then consider fly control or electric fly killer servicing.

Daily habits matter as much as the contractor. The FSA's sheet for caterers says to inspect deliveries and refuse any with gnawed packaging or insects, leave no food or dirty plates out overnight, and keep bins lidded and clean. Add those checks to your opening and closing routine, and put reminders in your diary.

Pest control for offices is usually simpler. Food law normally stays out of the picture unless you run a canteen, so your duties come from health and safety law. Mice are the usual trouble, travelling through risers and ceiling voids and feeding on crumbs at desks and in kitchenettes. For a single office with a first sighting, we recommend a survey and a one-off course. Move to planned monitoring if the problem returns, or if the building is shared and neighbours have it too.

In a shared building, your lease decides who does what. Read the repair, service charge and common parts clauses, then report activity to the landlord or managing agent in writing, with dates and locations. If your floor is treated and the risers are not, expect the mice to come back. Ask the landlord what it does in the shared areas, and keep the reply.

Shops face the food risk at the back of the shop. Deliveries can bring insects in, and stockrooms give mice cardboard and quiet. Low-risk shops may be inspected but not given a rating, according to the FSA, but the duty to control pests still applies if you sell food. Stack stock off the floor and away from walls so that you can see behind it, and rotate it. If mice have reached a shelf, deal with the whole batch and not just the torn packet, for the Article 14 reason above.

Warehouses add scale, loading doors and birds. If you store or transport food, you are a food business, and section 13 of the 1949 Act applies to you. Keep dock doors shut when not in use, check goods in, and leave a clear strip along walls so bait points and droppings can be seen. Birds in the roof need proofing as the first answer. Natural England's general licence GL41 covers feral pigeons in England for public health and safety reasons during 2026, but only authorised people may act under it, and it is best to take advice. Our pigeon control guide has more.

Hotels combine a food business, a workplace and a place where guests carry things in. Bed bugs are the pest that sets them apart. Westminster City Council expects businesses to have a bed bug procedure within their pest control procedure, to train staff to spot blood spotting on linen and mattresses, and to log every check, even those that find nothing. We recommend taking an affected room out of use, leaving the contents where they are, and treating the rooms either side as suspect until they have been checked. Our guide on getting rid of bed bugs explains why moving items spreads them, and bed bug treatment sets out the service.

Landlords and managing agents need to separate flats from common parts. Bin stores, chutes, stairwells, basements and roofs are the usual trouble spots, and the lease says who must maintain them. Shelter notes that overflowing bins and blocked chutes can attract vermin, that housing hazards include access for pests and poor refuse storage, and that whole blocks may need treating to clear an infestation fully. Treating one flat in a block with shared ducts rarely works. Our cockroach guide explains why heating ducts carry them between flats, and pharaoh ant control raises the same issue in multi-occupancy buildings.

Agents should check two more things. Section 4 of the 1949 Act lets a council serve notices on both owner and occupier, so an absent freeholder can still receive one. And if you recover the cost through residential service charges, a pest contract of more than 12 months is a qualifying long-term agreement: consultation applies if any leaseholder's contribution would exceed £100 in an accounting period. Consult before you sign, or take advice on what you could recover.

Schools fall under HSE, not the council, for health and safety. The Food Safety Act's definition of business includes schools, so treat a school kitchen as a food site. The Department for Education's Get Help Buying for Schools service lists a pest control framework, reference Y23013, which runs to 31 January 2029 and includes preventative surveys. HSE warns that children and pets can be harmed by anticoagulant rodenticides, partly because of how they look and smell. We recommend scheduling treatment in holidays or after hours, keeping any bait in locked, fixed boxes well away from pupils, and asking for non-toxic monitoring first.

Integrated pest management means using several methods in a sensible order instead of relying on poison. HSE lists it among the principles of the rodenticide stewardship regime, and its advice is to consider good hygiene, physical barriers and traps before anticoagulants, and to minimise their use wherever possible. It also says that limiting use helps prevent resistance. In practice, a good plan spends more of its time on doors, drains and bins than on bait.

Monitoring is how you know the plan works. Use non-toxic monitors for rodents, insect monitors in kitchens and stores, and your own staff sightings log. Plot activity on a site plan so a trend shows up. A monitor that catches nothing is still useful evidence, and Westminster's bed bug guidance asks for every check to be logged even when nothing is found. Fix one person as the site contact, because the Ole & Steen case shows what happens when a warning reaches a business and nothing follows.

Three legal limits shape what a contractor can offer. Ask about each one if a plan looks unusual.

Keep one pest file for each site. It should hold your written procedure, the site plan, safety sheets for any products used, contractor reports, your own checks, sightings, and proof of completed actions. Photos of repairs and dated invoices are excellent evidence. Article 5 of Regulation 852/2004 requires food businesses to keep records that show their procedures are applied effectively, in proportion to their size. It says records must be kept for an appropriate period without giving a number, so choose one, write it into your food safety procedures, and make sure it covers at least your last two inspections.

Add a monthly review. The FSA's advice for caterers is to record your contractor's visits and their feedback or action points, then note when you carried them out. That last step is the one to watch. Its Safer Food, Better Business diary includes a four-weekly review, which is a natural place to read the last report, close open actions and look for a trend. Westminster said of Ole & Steen that procedures existed on paper but were not put into practice, and The Caterer reports that the investigation included a review of pest control records. Treat your file as something an officer will read line by line.

Be careful with honesty in those records. Under regulation 17 of the 2013 Regulations, knowingly or recklessly giving an officer false or misleading information is an offence. If you missed a check, leave the gap and note why. A gap looks poor, but a forged entry can make things far worse.

Audits by customers, insurers or head office can ask for more than the law does. Get their standard in writing before you request quotes, and give it to the contractor, so the visit frequency and report format can be priced properly the first time. Nobody can honestly promise an audit pass in advance, so treat any such promise with caution.

The service report is the document everything else rests on, so judge it as an inspector would. It should tell a stranger what was checked, what was found, what was used and what must happen next. Ask to see a sample, and check that it contains the following.

A pest control contract buys planned attention and a paper trail. A one-off course buys a solution to a known problem. Neither is automatically cheaper. A contract can be poor value for a dry office with no history, and a run of one-offs can cost more than planning in a busy kitchen, while leaving no pattern for an inspector to see.

Answer the three questions in the drawing, in order. If you have a live infestation, deal with that first. A contract signed in the middle of an infestation should state whether clearing it is included, and our own contracts page lists existing pest issues as something to settle before a contract starts. For a wider view on budgets, see our pest control cost guide.

Do not compare headline monthly figures. Two quotes can differ because one includes call-outs and proofing and the other does not. Get at least two written quotes on the same scope, then lay them side by side using the table below. Redbridge Council's 2026/27 list shows why the scope matters: commercial rodent treatment starts from £280 plus VAT, and it says officers may charge more for larger premises or enter into annual service agreements.

Walk the site with the surveyor if you can. A quote written without a visit can only guess at your risk, and the survey is the best test of how well the firm knows commercial premises. Ask us the same questions as anyone else. A good contractor will answer them in writing without hesitation.

Stay calm and work through the list in order. The aim is to protect food and people first, then to preserve the evidence. If you have live activity or fresh droppings where open food is prepared or stored, we recommend stopping use of that area now, and closing altogether if you cannot keep food safe. It is better for you to make that decision than for an officer to make it for you.

We offer commercial pest control in London for business premises, quoted per site. Tell us the business type, layout, operating hours, affected areas and access needs, along with any food-handling or public-facing spaces. We then review the pest concern and any monitoring or visit needs, and confirm the scope, frequency, final price and reporting requirements before booking.

There is no fixed commercial starting rate. The price depends on premises type, size and operating hours, pest risk, affected areas, visit frequency, and monitoring, reporting and access requirements. Ongoing contracted visits for sites that need regular monitoring can be discussed on our pest control contracts page, and that price is also confirmed before booking. If you want to know what the problem is first, start with a pest inspection.

Our published per-pest starting rates, such as mice control from £99, rat control from £109 and cockroach control from £119, are listed on our prices page. They are starting rates, and a business site may be priced differently, so use the written quote and not the list. Ask us about visits around trading hours when you get in touch.

We are based on Clements Road in Ilford, cover commercial pest control across London, and carry public liability insurance. Phone lines are open Monday to Saturday, 8am to 8pm. If you are near us, our Ilford pest control page has the local detail.
