Key Findings


Chart 1: Research and Development (R&D) spend in Northern Ireland, 2018-2022* (cash terms, £millions)

*As methodological improvements have been implemented for the 2022 survey, users should consider comparisons between pre-2022 BERD data and 2022 BERD data (as well as future releases) with caution.


Key Points

In 2022 some £1,120.1 million (m) was spent on R&D by Businesses (BERD), Higher Education establishments (HERD) and Government departments (GovERD) in Northern Ireland (0.7% less than in 2021). Of this £1,120.1m, 75.9% was spent by Businesses, 21.6% by Higher Education Establishments and 2.4% by Government Departments.

Since 2018, Business R&D spend has increased by 28.6% in cash terms (14.1% in real terms).

In 2022, just under half of all business expenditure on R&D can be attributed to the Services sector (£385.2m; 45.3%).

The methodology employed to produce Business R&D spend estimates has been improved to better represent R&D performance across the Northern Ireland economy. This improvement has produced figures which provide the best current estimate of Business level R&D spend at the Northern Ireland level and has been validated against other available data.


Introduction and Context

 

Total R&D Expenditure


Total R&D Spend in Cash Terms

Users should note that the statistics in this ‘Total R&D Expenditure’ section have not been impacted by any of the redevelopment work undertaken for the BERD data and as such are classified as Accredited Official Statistics.

In 2022, the total expenditure on R&D in Northern Ireland (NI) in cash terms was £1,120.1 million (m). The majority of this, (75.9%) was carried out by Businesses (BERD), while 21.6% was undertaken by Higher Education Establishments (HERD) and 2.4% by Government Departments (GovERD).

There was a decrease of £7.6m in total R&D expenditure between 2021 and 2022. The decrease of £30.9m in Business spend across the year was offset by an increase of £22.7m in Higher Education spend during the same period. Government spend remained stable (up £0.6m over the year).

Total R&D Spend in Real Terms

Total expenditure on R&D in Northern Ireland decreased by 5.5% in real terms between 2021 and 2022 and increased by 10.3% since 2018.

Business Expenditure


Business R&D Activity in Northern Ireland by Company size

Users should note that the figures in this ‘Business Expenditure’ section are classified as Official Statistics as per the ‘Accredited Official / Official Statistics Designation of Northern Ireland BERD Statistics’ section above. Due to the break in the time series between 2021 and 2022, we have not made yearly comparisons for any BERD data below and users should also take caution when comparing with 2022 data with previous years.

In cash terms, Small and Medium sized Enterprises (SMEs, 0-249 employees) accounted for 47.8% of BERD in 2022. Large firms (250+ employees) accounted for 52.2% of BERD.

Chart 4: Business R&D expenditure by company size (persons on payroll), 2018-2022 (cash terms, £millions)

The European Commission defines Small Medium Enterprises (SME) as being enterprises with less than 250 employees and large companies as being enterprises with more than 250 employees.



Business R&D Activity in Northern Ireland – Employment

There were 16,270 FTEs working in an R&D role in 2022. Those working in a research role (PhD students, graduates and scientists) accounted for 41.1% of FTEs in 2022, technicians (those who perform scientific and technical tasks under the supervision of researcher) accounted for 31.0% and 27.9% were “other” staff (support, secretarial and clerical staff involved in R&D).

Chart 5: Business R&D FTE employment in NI, 2018-2022

Estimates of employment in R&D are best produced on a full-time equivalent (FTE) basis where businesses convert employee hours working on R&D into FTE figures, providing a better indication of total labour input than a simple headcount.



Sectoral Breakdowns of Business R&D activity in Northern Ireland

Just under half of all business expenditure on R&D can be attributed to the Services sector (£385.2m; 45.3%). The ‘Professional, Scientific, Technical, Administrative and Support Service Activities’ sector was the largest sub-sector in 2022, accounting for £208.9m (24.6%) of BERD spend.

Just over two-fifths of all business expenditure on R&D can be attributed to the Manufacturing sector (£367.1m; 43.2%). Almost half (£172.0m; 46.9%) of R&D spending in the Manufacturing sector was accounted for by companies involved in ‘Engineering & Allied Industries’.

Business R&D activity in Northern Ireland – UK regional comparisons

BERD spend across the UK as a whole totalled £49,942m in 2022. The vast majority of this spend (91%) occurred in England (£45,341m). Over three-fifths of the spend in England occurred within the East of England, London and the South East. Companies in Northern Ireland spent £851m on R&D in 2022, this equates to 1.7% of the total UK BERD figure.

Table 1: BERD by UK country or region, 2022 (£millions)

UK Region Total BERD (£millions)
UK £49,942
East of England, London, South East £28,354
East Midlands, West Midlands, South West £9,460
North East, North West, Yorkshire and the Humber £7,527
Scotland £2,731
Wales £959
Northern Ireland* £851
Activity of GB owned businesses in Northern Ireland £61

*The sum of the UK regions isn’t equal to the total due to a small amount (£61m) of BERD being identified as occurring in NI by GB businesses, this BERD is out of scope for the NI BERD total. For more information see the ‘Measuring R&D Data’ section above and the ‘NISRA’s Northern Ireland BERD figure in comparison to ONS’s Northern Ireland BERD figure’ section below.


Business R&D activity in Northern Ireland by Local Government Districts

Just over two-fifths (43.2%, £367.9m) of total BERD was attributed to companies in the Belfast Local Government District (LGD) in 2022. At £113.4m, companies in Armagh, Banbridge & Craigavon LGD accounted for 13.3% of total BERD in 2022.

Fermanagh and Omagh £24.7
Causeway Coast and Glens £18.1
Mid and East Antrim £15.8

Funding of Business R&D activity in Northern Ireland

The funding of business R&D expenditure comes from a number of sources: the companies’ own funds, a parent company, NI Government departments including Invest NI, other UK Government bodies, and overseas funding (e.g. EU), higher education establishments and other organisations.

The majority of funding for BERD in 2022 was self-funded by the companies carrying out the R&D work (63.4%). Just under one fifth of funding came from a parent company (16.3%), while NI and UK government sources each contributed 1.7% and 4.8% respectively to BERD funding. Other sources accounted for the remaining 13.8% of BERD funding.

Higher Education Expenditure


Higher Education Expenditure on R&D (HERD)

Users should note that the statistics in this section have not been impacted by the redevelopment work undertaken for the BERD data and as such are classified as Accredited Official Statistics.

HERD expenditure increased over the year by 10.3% (£22.7m) to £242.2m in 2022. Block grants remained the largest source of funding for HERD work, accounting for 44.7% of total HERD funding.

Government Expenditure


Government Expenditure on R&D (GovERD)

Users should note that the statistics in this section have not been impacted by the redevelopment work undertaken for the BERD data and as such are classified as Accredited Official Statistics.

The UK Office for National Statistics (ONS) collects data on R&D expenditure within government establishments. Combining these data with BERD and HERD data provides a more complete picture of R&D expenditure in Northern Ireland.

There was an increase of £0.6m (2.4%) in GovERD spend in Northern Ireland over the year to £27.1m in 2022.

Methodology


Recent developments

Although our best available estimates at the time of publication, it has been established that there was under-coverage of small businesses in previously published Business Enterprise Research and Development (BERD) statistics up to the 2020 survey reference period.


Uplift factor approach for 2018-2021 survey data

For the previous 2021 Northern Ireland R&D publication, the 2018-2021 BERD statistics were adjusted to account for the under-coverage of small businesses.

Previously, the BERD survey sample was developed using a stratified sample design. The stratification variable was the known level of R&D performance of the businesses. This information was gained from previous NISRA R&D surveys and extra information from various sources such as the Office for National Statistics (ONS), Invest NI, SIC 72 companies (drawn from the NISRA Business Register and Employment Survey) and a filter question on the NISRA Annual Business Inquiry (which asks businesses whether or not they completed R&D during the year).

The NI BERD sample list may have been missing some R&D performers because of the design of the other relevant NISRA surveys. In other words, all IDBR businesses that were not sampled on these surveys had no potential to be added to the BERD sample list, so needed to be estimated for.

As a result, uplift factors were applied to the survey results for the 2018-2021 periods, which were otherwise prepared using the existing BERD survey results processes, to take account for this under-coverage in the BERD statistics (see the 2021 Northern Ireland Research and Development publication for more information on the uplift factor approach).

There is a good level of coherence between the uplifted figures for 2018-2021 BERD data and the figures obtained for 2022 BERD data using the new methodology, however users should still consider comparisons between 2018-2021 and 2022 data with caution.


Survey Design

As with previous years, the annual Business Enterprise Research and Development (BERD) Survey remains the main source of information for this report. This survey collects annual data on the nature and scale of R&D spend among NI businesses.

The BERD survey sample was redesigned to be more reflective of R&D performed across the Northern Ireland economy. It was developed using a stratified sample design, where approximately 1,500 Northern Irish businesses were selected as part of the 2022 sample.

Rather than relying on other NISRA business surveys to build and maintain the BERD sample, the new methodology draws business directly from the Inter-Departmental Business Register (IDBR) based on stratification by size band and industry, alongside census elements.

To maximise survey precision, the Neyman allocation approach to sampling is utilised. Neyman allocation is a sample allocation method that may be used with stratified samples. The purpose of the method is to maximize survey precision, given a fixed sample size. The survey universe is stratified by industry and employee size band, all businesses with over 250 employees or within certain industries are fully enumerated. In addition, some companies of special interest to government agencies (for example Invest NI clients) are added to the sample. This information is then grossed up to the reporting unit population, to ensure that results are representative of the sampled population.

Data validation is carried out on the returned forms ensuring internal consistency within the form, checking data fell within expected limits or by contacting the company for clarification where appropriate. For non-returns data is imputed using a methodology that takes account of previous returned data and the performance of other similar businesses.


Comparisons of Northern Ireland BERD Data across years

As methodological improvements have been implemented for the 2022 survey, users should consider comparisons between pre-2022 BERD data and 2022 BERD data (as well as future releases) with caution. This is in addition to the changes made for 2018-2021 BERD data – therefore users should also consider comparisons between pre-2018 BERD data and 2018-2021 BERD data with caution (see the 2021 Northern Ireland Research and Development publication for more information on the changes previously made for 2018-2021 data).

For the 2022 NI R&D release and future releases, the total BERD figure (£850.7m) refers to in-house BERD, rather than in-house plus purchased BERD as published in previous Northern Ireland Research and Development releases. This is being done to harmonise the NI BERD figures with BERD data published by the ONS, ensuring coherence and comparability between the two sources. This change has also been applied to previous years’ data in this release.


NISRA’s Northern Ireland BERD figure in comparison to ONS’s Northern Ireland BERD figure

It should be noted that the total BERD figure for Northern Ireland in this release is slightly lower than the regional estimate published by ONS, this is due to a small proportion of R&D being performed in Northern Ireland, but by GB businesses. While these businesses are in scope for the GB BERD survey carried out by ONS, they are not part of the Northern Ireland data collection process and are therefore excluded from the results published by NISRA. We have worked closely with ONS to ensure no duplication exists as a result.


NISRA’s NI BERD Data in Comparison to HMRC R&D Tax Credit Data

Another source of data on R&D expenditure is HMRC’s annual publication of R&D Tax Credits, both sources are compiled differently and for different purposes but both capture data in line with internationally recognised guidelines outlined in the Frascati Manual. NISRA’s BERD estimate is taken from an annual survey of R&D performers (see the ‘Survey Design’ section above for more information). HMRC’s R&D statistics are based on administrative data where businesses have applied for and received R&D tax credits. The two sources are similar but not exactly the same and there will always be some element of difference between them, there are known reasons for this, and these are outlined in more detail in ONS’s article from September 2022.

ONS’s analysis of the two data sources found that there has been a significant increase in the number and value of claims under HMRC’s small and medium-sized enterprise scheme and the current NISRA R&D methodology employed for the 2022 data is structured in a way that should be more reflective of R&D performed across the Northern Ireland economy.

The current NISRA BERD figures are closer to HMRC’s data than previously published (pre-2018) figures, as can be seen from Chart 11 below.

Accredited Official Statistics and Official Statistics Designation of NI BERD statistics

To maintain the quality of the Northern Ireland R&D statistics, this publication features a reduced number of detailed breakdowns compared with previous releases. While the existing Accredited Official Statistics designation for the Northern Ireland level R&D figures will remain, to help convey the developmental nature of the sub-NI components, the Northern Ireland Statistics and Research Agency (NISRA) has asked the Office for Statistics Regulation (OSR) to temporarily pause the Accredited Official Statistics status of more detailed breakdowns. OSR confirmed their agreement to this approach in their letter published on 8th December 2022.

All data tables used to inform this release are available in Excel and ODS format here.


The following NI R&D data tables have maintained their Accredited Official Statistics status:

Impact of methodological improvements on GERD

The GERD statistics measure total expenditure on R&D performed in Northern Ireland by all sectors (BERD, HERD and GovERD) of the economy. As the BERD sector is the largest sector by value of expenditure, the improvement to methods implemented in this BERD release affects GERD results. However, the impact is minimal as the improvement to methods have not significantly changed the total level of Business Expenditure on R&D in comparison to the uplift approach used for 2018-2021 data. Despite the limited impact, caution should be taken when comparing current BERD data to earlier years.


Impact of methodological improvements on GDP

The estimated percentage of gross domestic product (GDP) that was spent on R&D performed by businesses in Northern Ireland, which is usually published in the BERD results, is not available in this release as the ONS have not yet incorporated the improvements to the measurement of R&D among UK businesses into the calculations of GDP.

The ONS continue to work towards introducing these improvements into the national accounts, but the earliest opportunity to do so will be in 2025. In the interim the ONS are working to understand the impact that the R&D improvements will have on national accounts and GDP. Updates on this are intended to be released later in 2024.

In light of the above, while R&D is a small component of NI GDP, we are currently unable to quantify the impact of these changes on GDP. We will implement our improved R&D estimates at the earliest opportunity into the economic accounts.


BERD Survey Response Rate

For the 2022 survey, 1,545 forms were sent out to businesses believed to be performing R&D. Completed forms were returned by 956 businesses representing a response rate of 62%. Due to non-response, values were imputed for 589 companies.

Table 3: Comparison of response rates and spend coverage for 2018, 2019, 2020, 2021 and 2022 survey periods

2018 2019 2020 2021 2022
Percentage of sample that returned a form 71% 55% 60% 60% 62%
Spend coverage by receipted businesses 83% 80% 76% 78% 76%

Data collection since the 2019 surveys occurred during and post-pandemic, this may have resulted in lower response rates in comparison to pre-COVID-19 surveys.

Efforts were made to reduce the impact of a lower response rate. Namely, larger R&D contributors received more contact than usual to encourage a response and the survey response window was extended. As a result, 76% of total R&D spend in 2022 is covered by receipted businesses.


Estimates

Overall, estimates make up 24% of total BERD spend for 2022 (compared with 22% in 2021). Most of the imputations are calculated using one of three methods:

  1. For companies which were on the R&D survey the previous year – The median percentage change in total R&D spend across the year among responders within a given SIC code is used to estimate spend for those businesses in the same SIC code that failed to reply to the survey.

  2. For companies which were not on the R&D survey the previous year – The median employment to R&D spend ratio among responders within a given SIC code was calculated and then used to estimate spend for those businesses in the same SIC code using employment information collected from other surveys within NISRA’s Economic and Labour Market Statistics Branch.

  3. Non-responding companies which reported zero R&D spend the previous year are imputed to have zero spend for the current year.

Estimates for Invest NI companies were based on the value of offers made to promote R&D investment and the contribution of Invest NI’s assistance to total planned R&D expenditure. Estimates for Invest NI companies make up less than 1% of the total non-responding company spend in 2022. The remaining >99% are non-Invest NI estimates.


Revisions

These results are provisional and are subject to revision should additional information become available. Business estimates of R&D performance for 2020 and 2021 have been revised to take account of late returns.
