How to Consolidate Security and Cleaning Under One Supplier
For many commercial businesses, managing security and cleaning through separate suppliers creates avoidable administration. You may have different contracts, separate reporting systems, multiple site inductions and more than one contact when an issue needs resolving.
Bringing both services under one supplier can make your site easier to manage. However, consolidation only works when the specification is detailed, responsibilities are clear and each service keeps its own quality measures.
The right question is not simply whether one supplier is cheaper. It is whether one accountable partner can support your premises more consistently without weakening security or cleaning standards.
Is one supplier worth considering?
A combined contract can be worthwhile when security and cleaning already operate around the same premises, working hours and access arrangements. It is particularly useful for offices, managed commercial buildings, industrial sites and other facilities where both services need to work around occupancy patterns.
The main benefits usually come from reducing duplication:
- One point of contact for service issues, changes and recommendations
- One site induction covering access, emergency procedures and reporting
- Joined-up opening and closing routines between security officers and cleaning teams
- One set of reporting and escalation lines for incidents, defects and complaints
- Cleaning schedules aligned with security shift patterns
- Fewer contractor inductions for your internal facilities or property team
- Clearer accountability for day-to-day standards on site
- Simpler procurement and invoicing through one supplier relationship
This does not mean every task should be combined. Your security guards and cleaning operatives still need appropriate training, supervision and responsibilities. The benefit comes from coordinating the services properly, not from treating them as interchangeable.
A suitable provider should be able to explain how its manned guarding services and commercial cleaning services work together while maintaining the controls needed for each discipline.
Which tasks genuinely benefit from one contract?
The strongest case for consolidation is where the two services have regular contact with the same building, people and operating routines.
Access and site opening
Security personnel may manage access at the start or end of the working day, while cleaning teams arrive before staff or remain on site after hours. A shared schedule can clarify who is expected to open areas, provide access, check restricted spaces and complete the handover.
This avoids repeated calls between suppliers and reduces the risk of an area being missed because each contractor believed the other was responsible.
Shared site information
A single induction can cover building rules, access points, welfare facilities, emergency arrangements, restricted areas and reporting procedures. This is more efficient for you and gives both teams the same understanding of how your premises operate.
The induction should still include service-specific content. Security officers need clear guarding duties and escalation arrangements. Cleaning teams need clear task schedules, equipment guidance and safe working procedures.
Reporting and escalation
A joined-up reporting process can make it easier to identify patterns. For example, a cleaner may report an unlocked door, damaged equipment or a safety issue. A security officer may identify a spill, blocked route or area that needs attention.
One reporting route helps make sure the issue reaches the right person and is followed through. It also gives you a clearer record for contract reviews and improvement planning.
Scheduling around your working day
Commercial cleaning often needs to fit around staff attendance, visitors, deliveries and security coverage. A combined supplier can review these arrangements together rather than planning each service in isolation.
This may help you decide whether cleaning is best completed before opening, during quieter periods or after staff have left. The arrangement should be based on your premises and requirements, not on a standard schedule applied to every site.
How to scope a combined specification
A reliable contract starts with a proper site survey. The supplier should understand the building, the people using it, current service arrangements and the standards you need to maintain.
During the survey, expect to discuss:
- Building size, layout and access points
- Occupancy levels and operating hours
- Visitor, contractor and delivery arrangements
- Security risks and areas requiring regular attention
- Cleaning frequencies for offices, washrooms and communal areas
- High-use areas and tasks that need additional attention
- Existing complaints, incidents or service gaps
- Equipment, storage and welfare arrangements
- Reporting, audit and review requirements
The final specification should separate security and cleaning clearly, while also showing where they connect.
For security, this may include the number and timing of shifts, access control, visitor management, patrol duties, handovers, incident reporting and any reception responsibilities. Where licensed security work is required, you should confirm that officers hold the appropriate SIA licences. Weston Group’s verified credential is SIA Approved Contractor number WESESOSC01.
For cleaning, the specification should identify each area, the required frequency, the expected standard and any periodic tasks. It should not simply state “general cleaning”. A clear schedule might distinguish between daily commercial office cleaning, washrooms, communal areas, touchpoints, kitchen facilities, waste handling and periodic work.
How is the price built?
A combined price should be transparent enough for you to understand what you are paying for. Ask the supplier to show the split between security and cleaning rather than providing only one unexplained monthly figure.
The pricing exercise should normally consider:
- Security hours by day, night, weekday and weekend
- Cleaning hours by area and frequency
- Supervision and contract management
- Consumables such as washroom products and bin liners
- Cleaning equipment and machinery
- Uniforms, identification and site materials
- Holiday and absence cover
- Mobilisation and training
- Reporting, audits and review meetings
- Any additional or periodic tasks
Agree who owns and maintains consumables and equipment before the contract starts. If this is unclear, costs can become disputed and cleaning standards may suffer when products, machinery or replacement items are not available.
You should also ask whether the price changes when your occupancy, opening hours or site footprint changes. A tailored quote should reflect your actual requirements and make any assumptions visible.
Checks to complete before you consolidate
Combining services is a contract change, not just a supplier change. Take time to review the employment, insurance and performance implications before making a decision.
Staffing and TUPE
If existing cleaning or security staff are assigned to your contracts, the Transfer of Undertakings (Protection of Employment) Regulations, commonly known as TUPE, may apply. The position depends on the circumstances, so obtain appropriate employment law advice.
Ask how the proposed supplier will manage:
- Employee liability information
- Consultation with affected employees or representatives
- Existing pay, hours, holidays and length of service
- Recruitment and vetting requirements
- Absence, holiday and relief cover
- Training and licence monitoring
TUPE information may also affect the accuracy of the tender price. It should be addressed early rather than after the contract has been awarded.
Insurance and responsibility
Check that the supplier has suitable insurance for both security and cleaning activities. Confirm the relevant policy types, limits and renewal arrangements, including employers’ liability and public liability cover. Depending on the work, you may also need to discuss professional indemnity or fidelity risks.
The contract should explain responsibility for loss, damage, injury, chemical misuse, access failures and damage to your property. Your own advisers can help review the detailed wording.
Service levels and KPIs
Use one overall contract review structure, but keep separate measures for each service. Useful measures may include:
- Scheduled security shifts covered
- Required SIA licence checks completed
- Patrols or duties completed as specified
- Incidents recorded and escalated correctly
- Cleaning tasks completed to schedule
- Quality audit scores by area
- Re-clean requests and complaints
- Staff attendance and continuity
- Corrective actions closed by the agreed date
The provider should report results in a format your facilities or property team can use. A combined dashboard can be helpful, but it should not hide poor performance in one service behind good performance in the other.
Exit and notice terms
Review the contract length, notice period, break clauses, renewal process and exit support. You should understand how records, keys, equipment, access information and outstanding actions are handed back if the relationship ends.
Clear exit terms protect continuity and encourage good contract management throughout the service.
Pitfalls to avoid
The most common problem is an under-specified cleaning schedule hidden inside a broader guarding contract. If the cleaning duties, frequencies and standards are vague, it becomes difficult to monitor performance or challenge missed work.
Another risk is over-stretched supervision. Security and cleaning require different knowledge, training and quality checks. One contract manager can coordinate both services, but they must have enough support and time to supervise each discipline properly.
You should also be cautious about a low headline price that depends on unrealistic staffing levels. Ask how the supplier will cover holidays, sickness, training and changes in your operating hours. Reliable continuity is more valuable than a saving that creates gaps on site.
Finally, do not assume that one supplier automatically means joined-up working. Ask to see the mobilisation plan, reporting process, escalation structure and review timetable before you appoint them.
Questions to ask a provider
Use these questions when comparing facilities management companies in the UK or choosing a security guard company:
- How will you survey and scope both services at our premises?
- Which security and cleaning tasks would you combine, and which would remain separate?
- Who is our day-to-day contact, and who manages each discipline?
- How will opening, closing, access and handover routines work?
- How will you manage TUPE, staffing continuity and relief cover?
- Which staff require SIA licences, and how do you monitor them?
- Who provides and maintains cleaning equipment and consumables?
- What reports and KPIs will we receive?
- How are complaints, incidents and urgent requests escalated?
- What insurance cover is in place for both services?
- What are the contract, notice and exit arrangements?
- How will you review and improve the service after mobilisation?
If you need out-of-hours support, also ask how calls are handled and how attendance is arranged. With Weston Group, all calls are answered immediately, and attendance times depend on location.
A practical way forward
Security and cleaning under one supplier can improve accountability, simplify administration and support a more consistent site routine. The arrangement is most effective when the specification remains detailed, service-specific KPIs are retained and the supplier has the management capacity to oversee both areas properly.
