Heritage roots, modern compliance.

Tourism, Hospitality & Micro-Businesses

We handle seasonal revenue recognition, deferred income under FRS 102 Section 23, hospitality VAT and tronc setup, Furnished Holiday Lettings treatment, and simple FRS 105 micro-entity accounts.

Frequently Asked Questions —
County Durham Corporate Services

These FAQs are uniquely crafted for County Durham — Companies House formation, the area's advanced-manufacturing base, the NETPark technology cluster, its large construction sector, and its retail and tourism economy.

UK company formation is regulated under the Companies Act 2006 and administered by Companies House (Cardiff for England and Wales). For a private company limited by shares — the most common structure for County Durham SMEs, manufacturers, technology companies, and construction firms — the process involves: (1) Company name search via the Companies House WebCHeck database to verify availability and screen for prohibited and sensitive words (words such as 'Durham', 'Royal', 'British', 'Group', 'Holdings', 'Institute' may require approval or supporting evidence); (2) Drafting Memorandum and Articles of Association — most County Durham clients adopt the Model Articles for Private Companies Limited by Shares, with customisation for share-class structures, founder vesting, and pre-emption rights where technology companies and spin-outs plan to raise investment; (3) Form IN01 submission via Companies House WebFiling (electronic, £50 standard fee) or paper (£71, 8–10 working days) with registered office address (must be a physical UK address — we provide a Durham City, Bishop Auckland, or Chester-le-Street registered office where required), first directors, shareholders, share capital structure, SIC codes, and PSC declaration. Online incorporations are typically approved within 24 hours, with automatic HMRC Corporation Tax registration.
County Durham has a strong advanced-manufacturing and engineering base — the Aycliffe Business Park at Newton Aycliffe is one of the largest industrial estates in the North East, home to train manufacturing and a wide engineering supply chain, and manufacturing is consistently one of the area's largest sectors for both employment and jobs. Manufacturing and engineering accounting has distinctive requirements: (1) Job costing and work-in-progress valuation under FRS 102 Section 13 Inventories, with accurate absorption of direct labour, materials, and overhead; (2) Machinery, plant, and tooling capital allowances under Full Expensing — permanent for companies since April 2024 — significant for capital-intensive manufacturers; (3) R&D tax relief claims — process improvement, automation, materials work, and new-product development frequently qualify for the merged R&D Expenditure Credit (RDEC) scheme; (4) Contract and milestone revenue recognition for long order books and framework supply work; (5) Standard costing and variance analysis; (6) Retention and contract-variation accounting; (7) Supply-chain accounting with extended payment terms. We maintain specialist manufacturing chart-of-accounts templates in Xero, QuickBooks, and Sage 50, and work closely with capital-allowance and R&D claim specialists.
County Durham is home to the North East Technology Park (NETPark) at Sedgefield, a leading science and technology park, and Durham University anchors a significant research and knowledge economy that produces academic spin-out companies. Technology and spin-out accounting is distinctive: (1) SaaS, licensing, and IP-based revenue recognition under FRS 102 Section 23 — recognising revenue across the right period rather than on invoice; (2) R&D tax relief claims — deep-tech, materials, photonics, and software development frequently qualify for the merged R&D Expenditure Credit (RDEC) scheme, and getting the qualifying-expenditure boundary right is essential; (3) SEIS and EIS investment-readiness — we help technology companies and spin-outs obtain HMRC Advance Assurance, structure share classes correctly, and keep the clean cap-table and compliance records investors expect; (4) Intellectual property accounting — capitalising or expensing development costs correctly, and treating licensing and royalty income properly; (5) Grant accounting — Innovate UK and other research grants recognised correctly as capital or revenue grants under FRS 102 Section 24; (6) Share-option scheme accounting, including EMI option schemes; (7) Burn-rate and runway reporting that founders and investors rely on. We keep books investor-ready from day one.
Construction is the single largest sector by number of businesses in County Durham, spanning housebuilders, civil-engineering contractors, fit-out firms, and a large base of trades subcontractors, supported by the area's regeneration and development pipeline. Construction accounting has distinctive requirements: (1) The Construction Industry Scheme (CIS) — registering as a contractor and/or subcontractor, verifying subcontractors with HMRC, applying the correct deduction rate (0%, 20%, or 30%), and filing monthly CIS returns; (2) The VAT Domestic Reverse Charge for construction services, which shifts responsibility for accounting for VAT on most B2B construction work to the customer; (3) Contract and project revenue recognition under FRS 102 Section 23, with accurate treatment of stage payments, retentions, and contract variations; (4) Work-in-progress valuation and accurate cost-to-complete estimates; (5) Plant and equipment capital allowances under Full Expensing and the Annual Investment Allowance; (6) CIS deduction reconciliation and offset against PAYE / Corporation Tax liabilities; (7) Cash-flow management around retentions and slow payment. We keep clean, lender-ready construction books and handle the full CIS monthly cycle.
Retail is one of County Durham's largest sectors, and the area has a varied tourism and hospitality economy — from Durham City with its UNESCO World Heritage cathedral and castle and its university population, to the North Pennines around Teesdale and Weardale, the Auckland Project at Bishop Auckland, the railway heritage at Shildon, and the coast at Seaham. Retail, tourism, and hospitality accounting has distinctive needs: (1) Multi-channel revenue reconciliation across till, online, and marketplace platforms; (2) Inventory valuation and stock-turn analysis under FRS 102 Section 13; (3) Payment-processor and marketplace fee treatment; (4) VAT categorisation — accurate treatment of zero-rated and standard-rated goods, and the £90,000 registration threshold; (5) For hospitality — the distinction between standard-rated and zero-rated food and drink, service-charge and tip treatment, and tronc scheme setup; (6) Strongly seasonal revenue recognition and deferred income for advance bookings under FRS 102 Section 23; (7) For self-catering and holiday-let owners, the Furnished Holiday Lettings rules and the qualifying-occupancy tests. We help County Durham retailers, tourism, and hospitality operators keep clean, lender-ready books and manage cash through the seasonal cycle.
We offer two specialised bundles for County Durham businesses because the area's economy has two major pillars that need different accounting expertise. (1) Manufacturing & Technology Bundle (£2,400 / year) is purpose-built for County Durham advanced manufacturers and engineering firms — including those on the Aycliffe Business Park at Newton Aycliffe — NETPark science and technology companies, and Durham University spin-outs. It includes Companies House formation, 12 months of company secretary, 12 months of bookkeeping with job costing and FRS 102 Section 13 work-in-progress valuation or SaaS / IP-based revenue recognition, R&D tax credit claim support under the merged RDEC scheme, machinery capital allowance optimisation under Full Expensing, SEIS / EIS investment-readiness and HMRC Advance Assurance support, EMI share-option scheme accounting, year-end FRS 102 accounts, and Corporation Tax CT600 filing. (2) Construction, Retail & Hospitality Bundle (£2,150 / year) is tailored for County Durham construction and trades firms, independent retailers, and tourism and hospitality operators. It includes Companies House formation, 12 months of company secretary, 12 months of construction / retail / hospitality bookkeeping with the full CIS monthly cycle and VAT Domestic Reverse Charge handling, contract and retention accounting, multi-channel revenue reconciliation, stock control, hospitality VAT treatment and tronc setup, seasonal revenue recognition, year-end FRS 102 / FRS 105 accounts, and Corporation Tax CT600 filing. Both bundles carry a single fixed annual fee, a single point of contact, and no surprise bills — and both are priced to deliver genuine 50–70% savings versus traditional high-street accountancy firms.
