Everything You Need To Know About The New R&D Tax‑Relief For Surveyors

The UK government has consolidated its research & development (R&D) tax‑relief for surveyors. For accounting periods beginning on or after 1 April 2024, the previous SME and RDEC schemes have been replaced by a merged R&D expenditure credit (RDEC) scheme with a separate enhanced R&D‑intensive support (ERIS) regime for loss‑making, R&D‑intensive companies. Surveying firms developing new geographical information systems (GIS) methods or drone‑based measurement systems now need to navigate these rules in order to maximise support for their innovation.

Under the merged scheme, companies receive a taxable expenditure credit of 20% of qualifying costs. After corporation tax at 25%, the net benefit is roughly 15 p per £1 of qualifying expenditure, or 16.2 p where the company pays the small‑profits rate. Small and medium-sized enterprises (SMEs) that are not making a profit but spend a lot on research and development (R&D) can apply for a special support program for surveying SMEs, which offers an additional 86% deduction and a cash credit of This translates into up to 27 p for every £1 invested in qualifying R&D. Understanding these rates is essential for surveyors budgeting for innovation and preparing claims.

In this guide by expert R&D specialists at Apex Accountants, you’ll learn how to document R&D costs for surveying companies in the UK, meet the intensity condition and claim relief under the merged RDEC or ERIS schemes.

Which property surveying activities qualify as R&D?

To claim R&D relief, projects must seek a scientific or technological advance and attempt to overcome uncertainties. In property surveying, qualifying activities may include:

Developing new GIS algorithms. Examples include designing algorithms that reduce processing time for large point‑cloud datasets or integrating multiple coordinate systems into a unified model. Implementing machine‑learning techniques to automatically detect boundaries or classify land use from satellite imagery may also qualify.
Enhancing drone‑based measurement systems. Creating bespoke flight-planning software, developing custom sensors, or improving positioning accuracy to sub-centimetre levels can meet the R&D definition. Research into obstacle‑avoidance systems, real‑time data transmission and automated 3‑D modelling also qualifies.
Building novel data‑integration workflows. Projects that integrate LiDAR, photogrammetry, and ground-based survey measurements into a cohesive digital twin for a site often involve technical uncertainties. Developing secure cloud platforms for sharing survey data or automating quality‑control checks may be eligible.
Improving environmental surveying techniques. R&D includes work on measuring subsidence using satellite interferometry, mapping flood risk models or developing sensors to detect underground utilities. If the work requires overcoming technical barriers, it should be considered.

It is important to distinguish routine work from genuine R&D. Simply using commercially available drones or GIS software is not enough. The firm must show that it tried to achieve an advance that is not readily deducible by a competent professional and that uncertainties were resolved through experimentation.

Understanding the merged RDEC scheme

The merged RDEC scheme applies to all companies that carry out qualifying R&D and are subject to corporation tax. Key features include:

Expenditure credit rate – 20%. For each pound of eligible R&D spent, the company receives a 20% credit. This credit counts as trading income and is taxed, leaving a post‑tax benefit of around 15 p per £1, or 16.2 p where the small‑profits rate applies.
Eligible costs. Companies can claim for staff salaries, employer national insurance and pension contributions, subcontracted staff, externally provided workers, consumables (e.g., survey stakes, batteries), software licences (including cloud computing and data feeds) and a proportion of utilities used on R&D. Expenditure on capital assets cannot be included, though separate research & development allowances may apply.
Document R&D costs for surveying companies. Firms must maintain detailed records of the R&D project: objectives, uncertainties, systematic experimentation, and results. Timesheets should allocate staff hours spent on R&D. Keep copies of the invoices for subcontractors, software licenses, and consumables. Supporting evidence helps HMRC verify claims.
PAYE/NIC cap. The payable credit cannot exceed £20,000 plus 300% of the company’s total PAYE and NIC liabilities. Companies whose employees create or manage intellectual property and whose subcontracting costs to connected parties are below 15% of qualifying spend are exempt.

For property survey firms, qualifying expenditure often arises from staff time spent coding GIS tools, running field trials with prototype drones, processing data, and analysing results. To maximise the credit, apportion costs between eligible R&D and non‑R&D activities using a reasonable and consistent method.

R&D Intensive Support Scheme For Surveying SMEs

ERIS targets loss‑making SMEs whose qualifying R&D expenditure represents at least 30% of their total expenditure. The threshold was 40% for periods starting before 1 April 2024, and a one‑year grace period applies. If the intensity condition is met, ERIS offers:

Extra 86% deduction plus 14.5% cash credit. The company can deduct an additional 86% of eligible costs on top of the 100% deduction already taken. It can then surrender the resulting tax loss for a cash credit worth up to 14.5% of the surrenderable loss.
Effective benefit up to 27 p per £1. Because enhanced expenditure is 186% of the actual spend, the cash credit can reach 27 p for every £1 invested. This is 45% more generous than SME R&D relief (18.6 p per £1) and 67% more than the merged RDEC (16.2 p per £1).
Strict eligibility. The company must be unprofitable before the enhancement and satisfy the SME size criteria: fewer than 500 employees, turnover below €100 million, or a balance sheet under €86 million. If another entity owns 25% or more of the company, its headcount and turnover may need to be included.

ERIS is particularly valuable for start‑up surveying firms investing heavily in advanced measurement technology but not yet generating profits. It can provide crucial cash flow to fund further research.

Meeting the intensity condition

The intensity condition requires that qualifying R&D expenditure constitutes at least 30% of total expenditure. For surveying companies, total expenditure includes staff costs, subcontractors, rent, marketing, and other operating costs. To meet the threshold:

Identify all qualifying R&D costs. This includes R&D‑related salaries, subcontracted specialists (e.g., software developers), prototype materials, drone components and cloud computing fees. Exclude routine business expenses and commercial survey work.
Calculate total expenditure. Use figures from the profit‑and‑loss account prepared under GAAP; include pre‑trading costs and deductions from the tax computation where relevant. Do not include amortisation added back for tax or payments to connected companies.
Maintain accurate records. Use project codes to track R&D costs. Document time spent on R&D to justify the percentage. For connected companies or mismatched accounting periods, allocate costs using a reasonable method and apply it consistently.

If the company fails the intensity test in one year, a grace period allows an ERIS claim if the condition was met in the previous 12-month period and a valid SME or ERIS claim was made for expenditures incurred on or after April 1, 2023.

Steps for property‑surveying firms to claim R&D relief

Identify qualifying projects early. During project planning, determine which activities aim to achieve technological advances and involve uncertainty. Please maintain a concise technical description and record the start and end dates.
Record time and costs. Implement timesheets for staff working on R&D. Use separate expense codes in the accounting system for R&D materials, software, and subcontractors. Save invoices and contracts.
Decide between the merged RDEC and ERIS. Calculate whether your R&D spend meets the intensity condition (30%). Whether your company is profitable or not R&D‑intensive, the merged RDEC will likely apply; if loss‑making and R&D‑intensive, ERIS may deliver a higher benefit.
Check PAYE cap implications. Please ensure that PAYE/NIC liabilities support the claim, and kindly consider the £20,000 plus 300%. If exempt, confirm that employees create intellectual property and that connected‑party subcontracting stays below 15% of qualifying spend.
Prepare the additional information form. HMRC requires companies to notify them of an intention to claim and to file an additional information form before submitting the CT600 return. Provide details about the R&D project, the uncertainties faced, the advances sought, and the breakdown of costs.
File the claim through the corporation tax return (CT600). Include the R&D expenditure credit or the surrenderable loss and cash credit in the return. Remember that the RDEC is taxable; ERIS cash credits are not.
Retain records for HMRC enquiry. HMRC may request evidence of R&D activities and costs. Keep your technical narratives, timesheets, contracts, and financial records for at least six years.
