Charging and paying the levy
17 April 2023
2. Agenda
Aim
This is the first of three workshops which seek feedback and views on our proposals for an
infrastructure levy. This workshop focuses on how levy rates might be set and the levy charged
Agenda
1. Overview of the Infrastructure Levy
2. Levy rates and minimum thresholds (Chapter 2)
3. Breakout session 1
4. Charging and paying the levy (Chapter 3)
5. Breakout session 2
6. AOB and discussion
3. Overview: Infrastructure Levy
• Reforms to largely replace section 106 planning obligations and the Community Infrastructure
Levy (CIL) in England.
• Aiming to improve transparency, reduce delays, capture more value than the existing system and
deliver at least as much affordable housing.
• Levy chargeable on Gross Development Value (GDV) – above a minimum threshold
• Rates set and levy collected by charging authorities.
• Non-negotiable cash payment, with affordable housing delivered on site as an in-kind payment.
• The Levelling Up & Regeneration Bill provides the legislative framework – policy detail to be set
out in regulations (following consultation).
• Introduced through ‘test and learn’.

Supporting research
• University worked with six local authorities to produce 24 illustrative
models of hypothetical development.
• Compared the existing system with the proposed IL
• Estimated lower and upper bounds for the rates that the IL might take
• Lower bound describes the IL rate equivalent to the scale of developer
contributions under the policy-compliant implementation of the
existing system (in reality, contributions may be negotiated down)
• Upper bound is the maximum rate at which the IL could be set whilst
maintaining benchmark land value and a profit of 15% Internal Rate of
Return (IRR) to the developer
• Effectively describes a ‘window’ of rates at which the IL might,
theoretically, be set locally

5. University of Liverpool (2023) “Exploring the potential effects of
the proposed Infrastructure Levy”
• The range of values that IL could take could be very wide.
• Rural England, residential greenfield development, median house
price £2,500 per sqm) – 62 percentage points between the
estimated lower and upper bounds
• Assuming a Benchmark Land Value of £200,000/ha, maximum
rate at which the IL could be set whilst maintaining the BLV and
the profit motive to the developer of 15% IRR would be 87%.
• Smallest difference between the estimated lower and upper
bounds were brownfield developments.
• Sites typically have existing or previous commercial uses and
their Existing Use Values tend to be higher.
• Tend to be more complex with higher build/remediation costs.
• But remember – the lower bound here is based on policy
compliant developer contributions, and in reality they may
currently be negotiated downwards, meaning the window is
wider
7. Rate setting - overview
• Liability based on gross development value
of the completed development
• A minimum threshold will be set by the
local authority, below which the levy will
not be charged
• The levy will be charged at a set percentage
of the value above the minimum threshold
• The levy rates and minimum thresholds
should be set at levels which are
appropriate to development in the local
area.
• Balance between the capture of land value
uplift and the viability of development.
• Requires careful judgement around
premium that is allowed for landowners
above existing use value, in order to
incentivise a landowner to bring their site
forward for development and developer
getting suitable return on their investment.

8. Rate setting - overview
• Our approach to rate setting will be
delivered through a combination of
secondary legislation and statutory
guidance, as occurs with CIL now.
• We are testing the approach set out
here with LPAs, developers, chartered
surveyors and other stakeholders.
• We also intend to consult on draft
regulations

Proposed approach to viability assessment and
determining scope for infrastructure levy
EUV
Minimum
Threshold
Recap
• Aim to maximise Levy revenues whilst maintaining the viability of
development in their area
• Purpose of minimum threshold – costs that a developer has to
make to deliver a development should not be taxed
• LPAs will be able to set different rates and/or minimum thresholds
for different development uses and land typologies in their local
area – e.g. lower rates for brownfield development to reflect
higher existing use values and construction costs
• Allow authorities to set ‘stepped’ rates which increase at specified
future points. That will enable rates to be set with a greater buffer
initially, but which can be stepped up over time.
• Questions around what should be included in the minimum
threshold.

14. The minimum threshold
Construction
Fees & finance
EUV
Minimum
Threshold
It is proposed that the minimum threshold will comprise the main (non-
land) construction-related development costs and the value of the land in its
existing use
• base build costs
• site preparation costs (including demolition)
• costs of external works
• professional fees
• contingency allowance
• the existing use value of land
• Levy is charged only on the additional value of a development
• Infrastructure ‘integral’ to the successful functioning of a site (e.g. play
areas or drainage systems), will be delivered by developers.
• The expected cost of integral infrastructure should be accounted for when
setting rates, to ensure development remains viable.
15. Levy rates, land value and
developer profits
• The portion of the GDV above the minimum threshold is subject to the
levy – based on the rate set by the LPA
• Three components:
• The Infrastructure Levy
• Additional payment to the landowner for the land (above the EUV)
• The return to the developer (profit) based an Internal Rate of Return
(IRR)
• Viability assessment used to determine a levy rate that gives the
developer:
• an appropriate return on their investment (e.g. an IRR of 15%)
• sufficient sum to encourage a landowner to sell their land (i.e. above
the benchmark land value)
• A development is unviable at a levy rate that results in the amount
available to pay the landowner being less than the benchmark land value

Calculating developer profits and land value at a
particular levy rate to determine what rates are viable
for the purposes of preparing a charging schedule
• Increasing levy rate reduces
developer profit and amount
available for land purchase
• If the sum available for land
purchase (after deducting land
purchase fee) is greater than
‘benchmark land value’ levy rate
is viable
• Authorities will need to balance
the levy rate with the need to
ensure that development remains
viable. The premium that is
allowed for landowners above
existing use value, must
incentivise a landowner to bring
their site forward for
development.
17. Example: Greenfield site currently in agricultural use.
Average new build sale price for residential dwellings = £3,000m-2
Base build costs = £1,300m-2
Other ‘normal’ construction costs (incl. fees)= £374m-2
Existing Use Value of agricultural land = £20,000 per hectare (£2 m-2)
A development of 6 residential units of 100 m2 each on a 5000m2 plot
EUV per square metre of development =
Plot area x EUV (£m−2)
𝐺𝐼𝐴 𝑜𝑓 𝑑𝑒𝑣𝑒𝑙𝑜𝑝𝑚𝑒𝑛𝑡
=
5000 x £2

= 10000/600 = £16.67m-2

Minimum Threshold

Residual amount
= £3,000 – £1,692
= £1,308 m-2
A Levy rate of 30% would give a levy liability of £392.50 m-2 (£1,308 x 30%)
Running the case flow model at a levy at 30% and an Internal Rate of Return
of 15% would give the following outcome for the six-dwelling development:
GDV = £1,800,00 (£3,000 x 6 x 100)
Levy liability = £235,500 (£392.5 x 6 x 100)
Developer profits = £185,504
Surplus available to purchase land = £318,864
Benchmark Land Value = 10 x EUV = £100,000
The development would therefore be viable
18. LPAs will be able to set different rates and
thresholds for different development types (e.g.
residential or retail) and land typologies (e.g.
greenfield or brownfield) in their local area.

19. CIL
• With CIL – the existing ‘lawfully in-use’ floorspace can be offset (whether reused or
demolished) and there is no CIL charge for that floorspace
Infrastructure Levy
• With the Infrastructure Levy – we are considering the possibility of some developer
contributions being sought
• Rates will be substantially lower than the rates that will be applied to new floorspace and
the threshold will be higher
Change of use rate: A specific rate applied to the conversion or repurposing of existing floorspace
Replacement rate: A specific rate applied when floorspace is demolished and replaced
Existing use threshold: Higher than the main threshold (recognising higher build costs)
Treatment of existing floorspace
20. • PDRs which create additional floorspace can be subject to developer
contributions currently. However, most PDRs relate to small householder
development or do not create additional floorspace so may not fall within
the scope of developer contributions.
• Possible approaches include:
• Exemption from the Levy
• LPAs set their own rates
• Need to balance collecting more value and maintaining viability -
especially given these conversions constitute brownfield development
• One way would be to only charge the Levy when the value of the scheme
(per square metre) is over a certain threshold?
• The minimum threshold could be set through regulations with LPAs able
to set higher minimum thresholds. Schemes that do not create significant
uplift in land value would not be charged.
• A maximum Levy charge could be set for permitted development
schemes to protect viability. LPAs would retain the ability to charge the
Levy at that maximum amount, or at a lower rate, if they choose to do so.
Permitted development rights (PDRs)
21. Addressing the variability of Brownfield Land
• The scope for developer contributions to be exacted
on residential brownfield development is constrained
to higher value settings – equally true of the current
system.
• Local authorities will be able to set different rates for
different areas and typologies of development, and
offset existing floorspace, and the Levy will expand the
type of development upon which contributions are
sought.
• Possible risk if brownfield land values vary
substantially from those assumed in rate setting
• Mitigations might include additional offsets from the
Levy if specific circumstances are met – e.g. where
there is substantial variation between the existing use
value used to set rates, and the existing use value of a
particular site.
22. Getting the balance right
• Consistent theme – ensuring land value capture does not affect
viability. Land comes forward and developers want to develop.
• Research demonstrates potential to capture more value – particularly
on greenfield sites
• How should a local authority determine what is appropriate to pay a
landowner for their land
• Things to think about…
• Where should the rate be set: 25% or 87%?
• What do you get through the current system? What do landowners
currently expect to get? If you move to far, too fast, what are the risks?
• Testing your way, possibly through a stepped approach?
• What factors should be taken into account?
• What tools can help?
23. Charging schedule preparation process
• Developing evidence base in collaboration with key stakeholders
including neighbouring and overlapping authorities
• Public consultation. Opportunity for interested parties to submit
evidence that challenges the local authority’s assumptions
underpinning rates or minimum thresholds.
• Independent examination of draft schedule in public before
publishing recommendations
• Charging schedule published
Issues
• Aware of concerns that examinations will become much more
challenging than existing CIL examinations
• We will seek to design the process of examination to balance the
ability for landowners/developers to challenge inaccurate
assumptions, while also providing local authorities confidence
that proposed rates will not be argued down to ‘lowest common
denominator’ rates.
• We will also consider what areas to focus examination challenges
on.
Standardised approached?
• We are considering what elements of the rate
setting process could be standardised.
• Using uniform inputs and standard rate setting
models, with inputs being varied on a local basis?
Test and learn
• We will work with local authorities through
responses to this consultation and through the ‘test
and learn’ process to make sure tools provide
sufficient support.
• What additional support and tools will you need?
• Are there things you think are important to test
through test and learn?

24. Questions on setting rates and minimum thresholds
• Question 9: Do you agree that the Levy should capture value uplift associated with permitted
development rights that create new dwellings? Are there some types of permitted
development where no Levy should be charged?
• Question 10: Do you have views on the proposal to bring schemes brought forward through
permitted development rights within scope of the Levy? Do you have views on an appropriate
value threshold for qualifying permitted development? Do you have views on an appropriate
Levy rate ‘ceiling’ for such sites, and how that might be decided?
• Question 11: Is there is a case for additional offsets from the Levy, beyond those identified in
the paragraphs above to facilitate marginal brownfield development coming forward?
• Question 12: Do you agree that the following components of Levy design will help collect
more than the existing system:
• Charging the Levy on final sale GDV of a scheme?
• The use of different Levy rates and minimum thresholds on different development uses
and typologies?
• Ability to set ‘stepped’ Levy rates?
• Separate Levy rates and thresholds for existing floorspace that is subject to change of
use, and floorspace that is demolished and replaced
25. Breakout groups: Setting rates and minimum
thresholds
1. What do you consider to be the biggest changes in the process for setting rates?
2. What do you consider to be the key challenges and concerns?
3. What could government do to help address those challenges?
27. Charging and paying the Levy - overview
CIL
• CIL liabilities are set at the point planning permission is granted.
• Payment broadly alongside commencement.
• Does not reflect changes in the market that occur throughout scheme delivery.
Infrastructure Levy
• Liability will be based on GDV at completion reflected in the sales price of the development, or a valuation of the market price if
the development is not sold
• Responsive to market conditions
• Estimates of the final liability will be required earlier in the process of developing a site.
• Provide both developers and local authorities with an indication of the amounts they are likely to pay and receive respectively
• Enables the registering of that liability against the site as a land charge.
• Three-step process:

29. Example calculation of the
levy liability
• The charging schedule states that in
Zone A:
• Minimum threshold = £2000 psm
• Levy Rate is 35%
• A small residential development in
Zone A has six dwelling each with a
Gross Internal Area of 100sqm and a
sales price of £400,000 each.
GDV psm =
£400,000
100
= £4,000 psm
Taxable amount = GDV – Threshold
= £4,000 - £2,000 = £2,000
Levy liability = £2,000 x £35% = £700psm
Total liability for development
= £700 x (100 x 6) = £420,000
Simple!
Even with a string of section 73 permissions. The
final GIA and GDV determine the liability.
30. Questions on charging and paying the Levy (1)
Timing of levy payments
• Question 14: Do you agree with the process outlined in the flowchart (Table 3 in consultation
document) is an effective way of calculating and paying the levy?
• Question 15: Is there an alternative payment mechanism being more suitable for the Infrastructure
Levy?
Imposition of a local land charge
• Question 16: Do you agree with the proposed application of a land charge at commencement of
development and removal of a local land charge once the provisional levy payment is made?
• Question 17: Will removal of the local land charge at the point the provisional Levy liability is paid
prevent avoidance of Infrastructure Levy payments?
31. Questions on charging and paying the Levy (2)
Possibility for payment on account
• Question 18: Do you agree that an LPA should be able to require that payment of the
Levy (or a proportion of the Levy liability) is made prior to site completion?
• Question 19: Are there circumstances when an LPA should be able to require an early
payment of the Levy or a proportion of the Levy?
Valuations
• Question 20: Do you agree that the proposed role for valuations of GDV is proportionate
and necessary in the context of creating a Levy that is responsive to market conditions
