The Medway-Swale Arc was newly included on the UK Assisted Areas Map in July 2014. This guidance document gives some more detail about what Assisted Area status means for businesses located within, or thinking about locating within, this area, and about the Medway-Swale Arc itself.

What are Assisted Areas?

Assisted Areas are recognised in European state aid guidelines as areas that are less economically advantaged and that would benefit from additional support or development. A new UK Assisted Areas Map was published in July 2014 defining the boundaries of the designated areas, together with an Order of Parliament listing the wards covered by Assisted Areas.

Within European Commission guidelines, the approach adopted by the UK Government in defining areas on the UK Assisted Areas map took account of relative economic need, consultation to ascertain local priorities, and the potential to use Assisted Area status to encourage economic growth in that locality by levering-in private sector investment. Part of the aim is to help re-balance local economies both geographically and sectorally in areas which, whilst relatively disadvantaged, offer good opportunities for business creation and growth. There is a strong emphasis on manufacturing (because of its capital-intensive nature and reliance on extensive supply chains), but also on regeneration more broadly. Assisted Areas include a mix of urban, rural and coastal areas. The European Commission may carry out a mid-term review of the assisted area framework in 2017.

What are the benefits of Assisted Area Status?

Under European regulations, the Government can offer specific financial flexibilities to encourage new investments in Assisted Areas, particularly to boost employment. Assisted Area status does not confer a right to financial assistance: at present there is no discrete programme or targeted pot of money. The financial flexibilities relate to Regional Aid and Tax Allowances.

1) Regional Aid

Assisted Areas are the only places where regional aid can be granted. This is a state aid exemption under which aid can be granted by the public sector in certain circumstances as a proportion of costs for a new commercial project. It can support capital investment and wage costs of new employees.

Where aid is available, for example through central or local Government grant or loan programmes (such as Regional Growth Fund) or European schemes, the intensity of aid is 10% higher than would otherwise be available to small and medium-sized enterprises (SMEs). It also means that large firms, which would otherwise not be eligible for any aid, can be supported at up to 10% of certain eligible costs.

The intensity of aid and what it can be used for varies according to the size of the company. In the Medway-Swale Arc, the rates of aid applicable are as follows:


Investment in:

Small Firms e.g. <50 employees

Medium Firms e.g. 50 to 250 employees

Large Firms e.g. >250 employees

Setting up a new establishment;

Expansion of an existing establishment;

Diversification of an existing establishment (e.g. into different products)




Fundamental changes in the production processes carried out in an establishment.




 NB The wards which make up the Medway-Swale Arc are in an area fulfilling the conditions of Article 107(3)(c) of the EU Treaty; different rates apply in areas covered by Article 107(3)(a) (i.e. Wales and Cornwall). 

To be eligible, a new establishment should be fully functioning, autonomous and self-standing. Expansion or diversification of the product range of an existing establishment is only eligible provided the new activity is not already being carried out at that establishment or any others owned by the company within the Assisted Area.

"Eligible costs

There are two ways to calculate “eligible costs”: investment costs and wage costs.

Investment costs include material assets (such as land, building, equipment), and immaterial assets (such as transfer of technology, Patents, operating or patented and non-patented know-how licenses). For large enterprises, immaterial assets are limited to 50% of eligible costs.

Wage costs cover costs arising from job creation as a result of the initial investment (two-year wage cost).

Regional investment aid is subject to various conditions. Notably, the investment or jobs created should be maintained in the region (the geographic area of the scheme in question) for 5 years in the case of large enterprises, and 3 years for SMEs; and 25% of investment should be from the company’s own contribution or external finance, but totally free of public support.

Other forms of state aid

The European Commission’s 2014-20 Environmental and Energy Aid guidelines and General Block Exemption Regulations (GBER) set out other benefits specific to Assisted Areas. One form of aid set out in the GBER that may be available is for urban development projects co-financed by EU Structural and Investment Funds with private sector investment

Increased aid intensity is available for environmental and energy investments in Assisted Areas (e.g. investments in green technologies, research, development and innovation, or encouraging a low carbon economy). Within the Medway-Swale Arc, this would mean that aid intensity (as a percentage of the eligible costs) could be increased by 5% (possibly more for SMEs). Higher aid intensity – an increase of 10% – may be available for eco-innovations that address a double market failure, linked to the higher risks of innovation coupled with the environmental aspects of the project (e.g. resource efficiency measures). This increase in aid intensity is subject to conditions regarding the novel or substantially improved nature of the asset or project, its delivery of significantly higher environmental benefits and demonstration of significantly higher than usual technological, market or financial risks. 

In all cases, aid may not exceed 100% of the eligible costs. There are also rules restricting cumulation of state aid from different sources and programmes.

For specific advice on State Aid issues always contact BEIS in the first instance and where appropriate seek independent legal advice from a practice with proven expertise in this field.

See below about boundary issues.

2) Tax Allowances

Certain tax allowances are only available in Assisted Areas. These are:

  • Business Premises Renovation Allowance (BPRA), which offers an incentive to bring derelict or unused properties back into use; and
  • The Enhanced Capital Allowances permitted at some Enterprise Zones

(a) Business Premises Renovation Allowance (BPRA)

BPRA is a form of tax relief, intended as an incentive to bring back into business use derelict or business properties that have been unused for at least one year.  It gives an allowance of 100% for certain expenditure incurred when converting or renovating unused business premises in a disadvantaged area. The allowance is applied (i.e. set against tax liability) in the year in which the expenditure is incurred. Detailed guidance is available on the HM Revenue & Customs website .

BPRA started on 11 April 2007 and ended on 31 March 2017 (for Corporation Tax purposes) and 5 April 2017 (for Income Tax).  This allowance is therefore no longer available but the description below is retained for reference.

To qualify for BPRA, the person/business has to incur qualifying expenditure on a qualifying building to be used as qualifying business premises.

  • Qualifying expenditure is capital expenditure incurred when converting, renovating or repairing a qualifying building to be used as qualifying business premises. This covers building works, architectural and design services, surveying or engineering services, planning applications, and statutory fees and permissions.  Expenditure on acquiring land, extending a building or developing land next to a building does not qualify for BPRA; and expenditure for which other State Aid is received is also excluded. Certain specified items of plant and machinery also qualify for relief – see the HMRC website for details.
  • A qualifying building is a commercial building or structure in a disadvantaged area (i.e. a designated Assisted Area). It must have been unused for at least a year.
  • Qualifying business premises are premises used, or available for letting for use, for a trade, profession or vocation or as offices. Exceptions to this are where a person carrying on a relevant trade holds a relevant interest in them, or where the premises are previously used or available for use as a dwelling, or used wholly or partly for the purposes of a relevant trade.
  • A relevant trade is one in the following sectors, which are ineligible for BPRA: fisheries and aquaculture; shipbuilding; the coal industry; the steel industry; synthetic fibres; the primary production of certain agricultural products; the manufacture or marketing of products which imitate or substitute for milk and milk products; an undertaking in difficulty for the purposes of the General Block Exemption Regulation 651/2014 (a company is in difficulty if its latest accounts are not produced on a going concern basis); an undertaking subject to an outstanding recovery order (a recovery order applies where an undertaking is in receipt of state aid that’s been declared illegal by the Commission and are subject to an outstanding recovery action, ie they still need to repay the illegal aid); energy distribution and infrastructure; broadband networks; and the transport sector.

More detail is available in HMRC’s Capital Allowances Manual 45000. If you are not sure whether particular premises would be eligible, contact HMRC for advice.

(b) Enterprise Zones - Enhanced Capital Allowances

All Government-designated Enterprise Zones (EZs) can offer Business Rate discounts, and EZs in Assisted Areas can qualify for Enhanced Capital Allowances, at HM Treasury’s discretion.

The North Kent Enterprise Zone comprises three schemes, one of which - at Rochester Airport - is within the Medway-Swale Arc Assisted Area.  Only one form of incentive can be offered within the defined boundaries of an EZ site and for Rochester Airport the chosen incentive is Business Rate discounts.  Were very significant investment and job creation to be proposed for a defined part of the site, for which Enhanced Capital Allowances would be more advantageous, there might be scope to revisit these arrangements (this would require Government approval).  

Boundary issues: how can I find out whether land is within an Assisted Area?

There are tools on enabling search by postcode, and large-scale mapping showing individual building footprints (and their relationship to the boundary of the Assisted Area).

Where a site or building is located at the boundary of an Assisted Area, the awarding body will need to make an informed decision about whether or not the undertaking is eligible for Regional Aid. Factors that may be taken into account include where the entrance to the building is, whether the majority of the site is within the Assisted Area, and its formal address (e.g. for business rates purposes). For BPRA, where land or a building straddles the boundary, HMRC can make a just and reasonable apportionment of the qualifying expenditure: only the part of the premises within the Assisted Area will qualify for BPRA.
