Building a Transparent Waste Recharging Policy for Multi Tenant Buildings

Abstract#

A waste recharging policy tells each occupier of a multi tenant building what it pays for waste and why. This blog tests one question: what must such a policy disclose for an occupier to check its own charge and how many of those disclosures can a building evidence without weighing waste at source. It derives ten disclosures from the RICS professional standard on service charges in commercial property and the waste clauses of the Better Buildings Partnership Green Lease Toolkit and the GOV.UK Simpler Recycling guidance. It sets them beside four peer reviewed studies located through Google Scholar and platform data from Wastify AI. The finding is that a building allocating by floor area can write all ten disclosures but can fully evidence only four: 40%. It can evidence three in part and three not at all. The three it cannot support are the measurement method and the attribution of waste to each occupier and the treatment of contamination. The research explains why that matters. The fairness literature holds that a scheme perceived as fair is a scheme that is accepted and a field experiment with about 600 households found that written feedback raised recycling. A German county that weighs and attributes household waste cut residual waste from 165 kg to 55 kg per person per year: a fall of 66.7%.

Key Findings#

1. A building that allocates waste costs by floor area can state all ten disclosures of a transparent recharging policy but can fully evidence only four: 40%. Three more it can evidence in part. Three it cannot evidence at all: the measurement method and attribution and contamination [1 2 3].
2. The RICS standard says that the rationale for apportionment between tenants should be set down in writing and re examined periodically and that an amended apportionment should be rational and reasonable and clearly communicated to tenants. It asks managers to adopt a full open book approach to requests for information [2].
3. The dark green waste clause of the Better Buildings Partnership Green Lease Toolkit requires the landlord to maintain a Waste Policy and give the tenant a copy each time it is updated. It requires a segregation system that includes as a minimum food waste and paper and cardboard and glass and plastic [3].
4. Charging by weight changes outcomes. In the German County of Aschaffenburg with 32 municipalities and about 173,000 inhabitants residual waste fell from 165 kg per person per year in 1995 to 55 kg in 2013: a fall of 66.7% and a quarter of the 220 kg recorded for Germany overall [6]. In a field experiment with about 120 households in each of five conditions written feedback on recycling raised both participation and the amount recycled but did not change contamination [7].
5. In one anonymised London building allocating by verified weight the largest of 31 occupiers produced 26.02% of all waste against an even share of 3.23%: about eight times as much. Across 218 building month cost records Wastify AI allocated £583,277.08 by verified weight: an average of £2,675.58 per building month [1].

1. Introduction#

1.1 The Question#

Most multi tenant buildings have a rule for dividing the waste bill. Few have a policy. A rule divides a number. A policy tells each occupier what is measured and what is charged and on what basis and what it can inspect if it disagrees. The difference matters most when a tenant asks a question that the rule cannot answer.

This blog asks one question. What must a waste recharging policy disclose for an occupier to check its own charge and how many of those disclosures can a building evidence without weighing waste at source. The question can be tested. If every disclosure could be evidenced from invoices and lease plans the allocation method would make no difference to transparency. Section 3 shows that three of the ten cannot.

1.2 Why This Matters Now#

Three developments put the waste recharging policy in front of landlords and occupiers this year.

First the RICS professional standard Service charges in commercial property took effect in its 2nd edition on 31 December 2025. Section 4.2 states that the rationale for the apportionment between tenants should be set down in writing and re examined periodically. It states that an amended apportionment should be rational and reasonable and clearly communicated to tenants [2]. A building that changes how it splits waste costs is now expected to write the reason down and explain the change.

Second Simpler Recycling reaches every workplace in England by 31 March 2027. Workplaces have had to separate dry recyclables and food waste from residual waste since 31 March 2025 and businesses with fewer than ten full time equivalent employees have until 31 March 2027 under the micro firm exemption [4]. The guidance notes that compliance notices may be issued to landlords or facilities management companies that present waste on behalf of the waste producer [4]. In a multi tenant building that is often the landlord.

Third the green lease is spreading. Research on how green leases evolve in the UK and Australia found a growing trend towards green leases in prime offices but not in retail or sub prime offices. Landlords usually introduce them and they vary in ambition and enforcement [8]. The most ambitious waste clause in the UK toolkit makes a written Waste Policy a lease obligation [3].

1.3 Building on Research Blogs 01 to 03#

This blog is the fourth in the Wastify AI research series. Each earlier blog tested one part of the recharging chain [9].

• Research Blog 01 Found that a tenant query on a floor area basis ends at a contractor invoice while a query on verified weight reaches a photograph in five steps.
• Research Blog 02 Found that in 2024/25 residual waste sent to energy from waste carried a median gate fee of £121 per tonne against £24 for food waste sent to anaerobic digestion.
• Research Blog 03 Found that the independent accountant review of service charge accounts excludes the allocation and apportionment of the service charge.

A policy is where those findings meet the occupier. It is the document that says which of them a building can stand behind.

1.4 Scope and Structure#

This blog covers waste costs recovered from occupiers in multi tenant commercial buildings in England. It proceeds in six sections.

• Section 2 Describes the method and the sources.
• Section 3 Sets out four findings.
• Section 4 Discusses what they mean for managing agents and occupiers and landlords.
• Section 5 States the limitations.
• Section 6 Answers the question.

It does not draft lease clauses or give legal advice on any particular lease.

Write a recharging policy every occupier can check for itself. Wastify AI delivers waste intelligence for commercial buildings where every disclosure in the policy rests on a weighed and photographed record.

2. Method#

2.1 Research Design#

The blog combines three evidence streams. The first is a review of the primary rules and model clauses that tell a building what to disclose about service charges and waste. Ten disclosures were derived from them. Each disclosure was then scored for a building that allocates by floor area and for a building that allocates by verified weight: can it be stated and can it be evidenced in full or in part or not at all. The second stream is peer reviewed research on the fairness and effects of charging for waste. Four studies were located through Google Scholar and each abstract or summary was read at the publisher or at a recognised index. The third is platform data from Wastify AI.

2.2 Sources#

Every external source was opened directly on 8 October 2026 and each reference carries that access date.

2.3 Platform Data#

The building data describes one anonymised multi tenant office building in London with 31 occupiers in one month read from the live platform on 16 August 2026. Its waste costs of £15,122.08 were held against five components and allocated by verified weight. The cost ledger holds 218 building month records entered between January 2025 and 16 August 2026 with £583,277.08 allocated to occupiers. The container register holds tare weights for eleven bin types from a 2.5 kg slim bin to a 58 kg container of 1,100 litres. Statement and privacy features are taken from the published tenant recharging page.

Platform totals were read from the live counter on the Wastify AI homepage on 8 October 2026. The counter carried a timestamp of 7 October 2026. It showed 5,124,000+ kg weighed at disposal and 953,000+ verified weighings. It showed £660,000+ recharged on verified data and 380+ companies reporting through the platform. Public totals are rounded down. No building or tenant is identifiable.

2.4 Calculations#

Four of ten disclosures fully evidenced on a floor area basis gives 40%. Three evidenced in part gives 30% and three not evidenced gives 30%. The Aschaffenburg reduction is 165 kg minus 55 kg which gives 110 kg and 110 divided by 165 gives 66.7%. The 2013 figure of 55 kg divided by 220 kg for Germany overall gives 25%. A reduction of 110 kg per person across about 173,000 inhabitants gives 19,030 tonnes a year and is stated as about 19,000 tonnes. About 120 households in each of five conditions gives about 600 households. An even share across 31 occupiers is 100% divided by 31 which gives 3.23% and 26.02% divided by 3.23% gives about 8.1. The average allocation per building month is £583,277.08 divided by 218 which gives £2,675.58. Every derived figure was recomputed from the stated inputs before publication.

3. Findings#

3.1 What the Rules Ask a Policy to Disclose#

No single rule defines a waste recharging policy. Three sources between them describe what one should contain. Table 2 sets out the provisions used to derive the ten disclosures.

Table 2: Provisions used to derive the ten disclosures

Source: RICS standard [2] and Better Buildings Partnership Green Lease Toolkit [3] and GOV.UK guidance [4].

Read together the sources ask for more than a percentage. The RICS standard asks for the basis of each share and an open book approach and a clear explanation of any change [2]. It asks for the rationale to be set down in writing which is the nearest the standard comes to asking for a policy [2]. It states that costs of services provided directly to one tenant should go to that tenant rather than into the general service charge [2]. The toolkit asks for a segregation system and a written Waste Policy and data on how much waste leaves the building and how much is salvaged [3]. The GOV.UK guidance places separation duties on every workplace and allows enforcement against a landlord that presents waste for its occupiers [4].

3.2 Ten Disclosures and What Each Building Can Evidence#

Table 3 sets out the ten disclosures. Each is scored for whether a building can state it in the policy and whether it can produce evidence for it when an occupier asks.

Table 3: Ten disclosures of a transparent waste recharging policy

Source: derived for this blog from [2] [3] [4] and the Wastify AI record structure [1].

A floor area building can write every disclosure. It can fully evidence four. That is 40% of the policy in full and 30% in part and 30% not at all. It can show which costs are recharged because it holds the invoices. It can show the basis because it holds the matrix. It can protect the privacy of other occupiers and it can run a review procedure. It can evidence three more in part: the bins exist but their use is not measured and the occupier report can carry only building totals and the evidence on request stops at the invoice. Three disclosures it cannot evidence at all.

3.2.1 The Three Disclosures Floor Area Cannot Support#

The first is the measurement method. Without a scale the policy can only say that quantity is taken from the contractor or from a container count. The second is attribution. Floor area links cost to space and not to the occupier that produced the waste. The RICS principle that direct costs belong to the tenant that caused them cannot be applied to waste that nobody attributed [2]. The third is contamination. A rejected load cannot be traced to a floor or an occupier so its cost is shared by everyone.

The platform data shows what is lost. In the sample building the largest of 31 occupiers produced 26.02% of all waste against an even share of 3.23%: about eight times as much [1]. A policy built on floor area has no way to disclose that fact because it never measured it. A waste audit can sample what is in the bins on a given day. It cannot attribute every disposal across a year.

3.3 Why Transparency Changes Behaviour#

A policy is not only a defence against disputes. The research on charging for waste suggests that what a scheme discloses shapes how people respond to it. Table 4 summarises four studies.

Table 4: Peer reviewed studies on fairness and feedback in waste charging

Source: published abstracts and article text of the four studies [5 6 7 8].

The design study of perceived fairness in pay as you throw starts from a simple premise: the higher the perceived fairness of a charging system the higher its acceptance and therefore participation [5]. A charge that an occupier cannot check is hard to perceive as fair however carefully it was calculated.

The Aschaffenburg pay as you throw case shows what a long running scheme can achieve. The county charges by weight: every bin is coded and each collection truck carries a reading device and a weighing device [6]. That is attribution and measurement at the kerb: the same two disclosures a floor area building cannot evidence. Residual waste fell from 165 kg per person per year in 1995 to 55 kg in 2013 against 220 kg for Germany overall. Across about 173,000 inhabitants the fall of 110 kg per person is about 19,000 tonnes of residual waste a year. The county reported a collection rate for recyclables of up to 86% and a waste fee in 2013 lower than before the scheme began in 1997. The fee rose by 10% in 1999 and again in 2000 and then fell by about 23% from 2002 to 2013 [6].

The field experiment on normative feedback assigned about 120 households to each of five conditions: about 600 households in all. Written feedback to individuals and to groups raised both the frequency of participation and the amount recycled. None of the interventions changed the amount of contamination [7]. Feedback moves volume. It does not fix contamination on its own. A policy needs a separate clause for each.

3.4 What Verified Weight Puts Behind Each Disclosure#

Weighing at source turns the three missing disclosures into records. Each disposal is weighed and attributed to the occupier through PIN based attribution at the kiosk and coded to a stream and photographed [1]. The weight is net of the container: the platform holds tare weights for eleven bin types from a 2.5 kg slim bin to a 58 kg container of 1,100 litres [1]. That record answers the measurement disclosure and the attribution disclosure in one step.

Costs are then allocated through five component cost allocation: collection and sacks and rental and management and ad hoc [1]. Rental is where equipment such as a baler or a compactor sits so the policy can state the basis for each line separately. Each occupier receives occupier statements with anonymised comparisons: it always sees its own breakdown by stream and by disposal outcome while other tenants are anonymised by default and league table visibility is the choice of the building manager [1].

When a figure is questioned the evidence disclosure is met by the walk down from invoice line to photograph in five steps [1]. The total itself can be checked by weighing every collection as bins leave the bin store [1]. In the published case study a multi tenant Central London estate raised verified recycling from 39% to 68% in six months after kiosks and weight based recharging and contamination alerts were introduced [1].

A policy is only as transparent as the record behind it. Wastify AI weighs and attributes every disposal so each line of the policy can be shown rather than asserted.

4. Discussion: What This Means for the Reader#

4.1 For Managing Agents Writing the Policy#

Table 3 doubles as a contents page. A policy that states all ten disclosures and labels honestly which ones rest on measurement is more credible than one that promises evidence the building does not hold. The RICS standard already asks for the rationale to be set down in writing and for any change in apportionment to be clearly communicated [2]. A move from floor area to weight based tenant recharging is such a change and the policy is the place to explain it.

Two practical points follow from the sources. The policy should name where waste from the common parts goes because it belongs to no single occupier. It should say how fit out waste is handled because the RICS principle on direct costs points to the occupier that caused it [2]. Buildings that collect through a waste chute should state how disposals are attributed when they reach the bin store.

4.2 For Occupiers Reading the Policy#

An occupier can test any policy against Table 3. The questions that matter most are the three a floor area building cannot evidence: how is our waste measured and how is it linked to us and who pays when a load is contaminated. An occupier that reports its own recycling rate needs the answer to the first two in any case. Small occupiers inside the micro firm threshold reach their Simpler Recycling deadline on 31 March 2027 and will need separation evidence for Simpler Recycling from the same records [4].

4.3 For Landlords and Green Leases#

The green lease clauses of the Better Buildings Partnership toolkit move step by step from a segregation system to shared data to a written Waste Policy with a salvage target [3]. Each step asks for more measurement than the last. Shared data on how much waste is removed and how much is salvaged is only as good as the method that produced it. A landlord that commits to the dark green clause is committing to disclose a measurement method whether or not it holds one.

5. Limitations#

This blog has five limitations that a careful reader should weigh.

1. The ten disclosures are derived by the author from the RICS standard and the toolkit and the GOV.UK guidance. No rule prescribes this exact list and a different reading could add or merge items.
2. The scoring in Table 3 describes a typical building on each basis. Some floor area buildings hold better records than others and some verified buildings may not use every feature.
3. The Aschaffenburg and feedback studies concern households in Germany and the United States. The fairness study concerns municipal schemes and states the link between fairness and acceptance as an assumption and not as a measured result. Commercial occupiers may respond differently. The Aschaffenburg paper gives the 1995 figure as 165 kg in its text and 163.0 kg in a table and the tonnage in section 3.3 is an estimate based on about 173,000 inhabitants.
4. The building data is one building in one month and the case study is one estate where several changes were made together. Buildings on the platform chose to measure their waste which is a selection bias.
5. Platform totals are rounded down and grow daily.

6. Conclusion#

A transparent waste recharging policy needs ten disclosures. A building that allocates by floor area can write all of them and can fully evidence four: 40%. It cannot evidence how waste is measured or whose waste it was or who caused a contaminated load. Those are the three disclosures occupiers ask about most. A policy can promise transparency. Only a record can deliver it.

The research adds a reason to close the gap. The fairness literature treats a scheme perceived as fair as a scheme that is accepted and a field experiment found that written feedback raises recycling. A county that weighs and attributes household waste holds residual waste at 55 kg per person against 220 kg for Germany overall. A building that wants to know which disclosures it can evidence today can start with a self assessment of building waste data in two minutes.

Frequently Asked Questions#

What is a waste recharging policy?#

A written statement of how waste costs in a building are measured and allocated and evidenced. It tells each occupier what it pays for and on what basis and what it can inspect if it disagrees.

What should a transparent policy disclose?#

Ten things: the costs recharged and the basis for each and the measurement method and the attribution method and the segregation system and contamination and occupier reporting and privacy and the evidence and dispute route and the review procedure.

Can a floor area building publish a transparent policy?#

It can state every disclosure. It can fully evidence four of the ten: 40%. It cannot evidence the measurement method or attribution or contamination because nothing is weighed or linked to an occupier.

Does the RICS standard require a waste policy?#

Not by that name. It requires an apportionment matrix. It also says that the rationale for apportionment should be set down in writing and that managers should adopt a full open book approach and clearly communicate any change in apportionment [2]. A waste policy is the natural place to meet those points for the waste line.

Who is the waste producer in a multi tenant building?#

Usually the occupier whose activity produced the waste. The GOV.UK guidance notes that compliance notices may be issued to landlords or facilities management companies that present waste on behalf of the producer [4].

Can occupiers see the waste data of other tenants?#

Each occupier always sees its own data. Other tenants are anonymised by default and any league table is the choice of the building manager [1].

Does feedback to occupiers change behaviour?#

The evidence says yes for volume. In one field experiment with about 600 households written feedback raised participation and the amount recycled but did not reduce contamination [7]. That is why a policy needs a separate contamination clause.

How quickly can an occupier get an answer about its charge?#

When the records exist the answer can be read from them. Living AI answers plain English questions about the weighings with the sources attached so a query about a stream or a month can be answered from the data itself.
