Groundworks finance: key facts
- Groundworks finance usually covers three things: plant you own (excavators, dumpers, rollers), muck-away and grab lorries, and working capital to bridge the gap until valuations are paid.
- Under the Housing Grants, Construction and Regeneration Act 1996 (section 109), a party to a construction contract is entitled to stage or periodic payments unless the work is specified or agreed to last less than 45 days.
- A clause making your payment conditional on the main contractor being paid by someone else ("pay when paid") is ineffective under section 113 of that Act, unless the party further up the chain is insolvent.
- Contractors deduct 20% under CIS from registered subcontractors (30% if not registered) unless you hold gross payment status. GOV.UK says deductions are not taken from VAT, materials you paid for directly, plant hired for the job or consumables you charge for.
- For gross payment status, a company's turnover (ignoring VAT and materials) must be at least £30,000 per director or £100,000 for the whole company; if it's controlled by 5 people or fewer, £30,000 for each of them.
- A limited company subcontractor recovers CIS deductions through its payroll (on the Employer Payment Summary) against PAYE it owes; deductions left at the end of the tax year are claimed as a refund.
- When the VAT domestic reverse charge applies, you don't charge VAT to a VAT- and CIS-registered contractor, so GOV.UK warns sub-contractors to plan for lower gross receipts and says you may make net repayment claims and can apply for monthly VAT returns.
- In England a business that transports waste must register as a waste carrier with the Environment Agency; registration is usually free if you only carry waste you produce yourself, otherwise it costs £191.02. Finance is subject to status and the lender's checks.
What does groundworks finance actually pay for?
For most groundworks contractors it falls into three pots: plant you run on your own jobs, the lorries that take muck away and bring aggregates in, and working capital to carry the costs of a job until the main contractor's valuation is paid. Each pot suits a different kind of finance.
A groundworks firm doesn't look like a plant hire company or a haulier to a lender, even though it owns diggers and lorries. Its income comes from subcontract packages: drainage, foundations, slabs, external works, roads and sewers. The money goes out on labour, plant, fuel, tipping and materials long before it comes back in.
| Need | Typical examples on a groundworks job | Finance that commonly fits |
|---|---|---|
| Own plant | Mini and 13 to 14 tonne excavators, forward-tip dumpers, rollers, plate compactors, breakers and buckets, a site welfare unit | Hire purchase or leasing on the machine (the asset side is covered in our plant finance guide) |
| Lorries | 8-wheel tippers, grab lorries, a tipper to run stone and spoil, a low-loader to move machines between sites | Vehicle hire purchase or leasing; the operator's licence comes with it (see HGV finance) |
| Starting a package | Drainage pipe, chambers, stone, concrete, rebar, muck-away and tipping charges, extra labour in the first weeks | A business loan, a revolving facility or a contract-specific working capital line |
| Waiting to be paid | Applied-for sums not yet certified, certified sums not yet due, retentions held back | Invoice finance (where the provider will fund construction debts), or a facility sized to your payment cycle |
| Tax timing | VAT on new plant bought on HP, corporation tax, PAYE, a year of CIS deductions waiting to be recovered | Short-term funding such as a VAT loan, or refinancing plant you own outright |
Most of this page is about the parts that are specific to groundworkers: the buy-or-hire decision, the payment cycle, CIS and the reverse charge, muck-away and the weather.
Should a groundworker buy plant on finance or keep hiring it in?
Owning makes sense for machines that are on your jobs almost all the time, like your main excavators and dumpers. Hiring in usually suits occasional or specialist kit, and machines needed for a single package. The difference that matters most for cash flow is that a hired machine can go off hire when a site floods or a job ends; a finance payment carries on.
Every groundworks business ends up with a mix of owned and hired plant. The question is where to draw the line. Some practical tests:
- How many weeks a year would it work? Look back at your hire invoices for the past year. A machine you've hired in almost continuously is a candidate to own; one that turns up for a fortnight on one job is not.
- Is the work it does tied to one contract? If you'd be buying a big machine for one package, ask what it will do when that package ends. Lenders ask the same question.
- Who operates it? Owned plant needs your own operator, servicing, transport and insurance. Hired plant can come with an operator.
- What happens in a wet January? Hire stops when you off-hire. Hire purchase and lease payments don't stop because the ground is waterlogged.
- Does owning it help you win work? Being able to start on site straight away with your own kit can matter to main contractors.
The CIS angle on hired plant
GOV.UK says contractors don't take CIS deductions from amounts you charge on your invoice for plant hired for the job, materials you've paid for directly, consumables or VAT. Plant you own and run yourself is a cost of your business, not a hire charge you're passing on, so it doesn't sit in that list in the same way. How your applications show labour, materials and plant can change how much is deducted, so set this up with your accountant rather than guessing. The contractor may ask for evidence such as receipts, and if you don't have it they'll estimate the cost of materials.
Why do applications for payment leave groundworkers short of cash?
Groundworks are front-loaded: the dig, muck-away, drainage materials and stone all happen in the first weeks of a job. You then apply for payment, the main contractor values it, and payment follows on the dates in the subcontract, often net of CIS and sometimes less a retention. The bigger the package, the bigger the sum you're carrying.
Picture a typical housing-site drainage and foundations package. In the first month you've paid wages every week, run two machines, paid for muck-away, and bought pipe, chambers and stone on supplier terms. Your first application covers that month. The contractor's valuation may come in lower than you applied for (disputed measure, dayworks not yet signed off, materials on site not included), and payment then follows on the due date in the subcontract. By the time it arrives you're two or three months into the job.
What the Construction Act gives you
- Stage payments. Section 109 of the Housing Grants, Construction and Regeneration Act 1996 says a party to a construction contract is entitled to instalments, stage payments or other periodic payments unless the work is specified, or agreed, to last less than 45 days. The parties agree the amounts and intervals; if they don't, the statutory Scheme for Construction Contracts fills the gap.
- No "pay when paid". Section 113 makes a clause ineffective if it makes your payment conditional on the payer being paid by someone else, unless that third party (or someone further up the chain) is insolvent.
- Right to suspend. Section 112 gives a right to suspend performance where a sum due isn't paid as the Act requires, after giving at least seven days' notice of intention to suspend, stating the grounds.
These rights apply in England, Wales and Scotland. They help you get paid on time; they don't make a long payment cycle any shorter. For contract disputes, get proper advice: this page is about funding the gap, not about the law.
How lenders see applications for payment
An application isn't an invoice the customer has agreed. Some invoice finance providers won't advance against construction debts at all, and many treat applications, contra-charges and retentions cautiously, because the final sum can move. Others specialise in construction and fund against certified valuations. If you're looking at invoice finance, say clearly how your work is billed: applications or straight invoices, how long certification takes, and how much is retention. That decides which facilities are even worth applying for.
How do CIS deductions affect a groundworks company's cash flow?
Unless you have gross payment status, the main contractor deducts 20% (30% if you aren't registered) from the labour part of each payment. A limited company gets that money back by setting it against the PAYE it owes each month, and anything left over at the end of the tax year has to be claimed as a refund, so a firm with a small payroll can have cash tied up with HMRC for months.
What gets deducted
Groundworks, including site preparation, excavation, drainage and foundations, is construction work under the Construction Industry Scheme. GOV.UK says contractors take deductions from what you're paid, but not from the parts of your invoice for VAT, materials you paid for directly, plant hired for the job, manufacturing or prefabricating materials, and consumable stores. Each month the contractor must give you a payment and deduction statement within 14 days of the end of the tax month. Keep every one: you need them to recover the deductions, and lenders often ask for them.
How a company gets the money back
For a limited company, GOV.UK says you use your payroll scheme: send your Full Payment Submission as usual, and an Employer Payment Summary showing CIS deductions for the year to date. HMRC takes the deductions off the PAYE you owe and you pay the balance. If deductions are larger than your PAYE bill, the excess carries forward to later periods in the same tax year; whatever is still left after the tax year ends is claimed as a refund. GOV.UK warns not to use the Corporation Tax return to claim them.
This is where groundworks firms get caught. A business with heavy plant and a small directly employed team can suffer more in deductions each month than it owes in PAYE, so the surplus builds up through the year. On paper it's an asset; in the bank it's money you can't use. A lender reading your balance sheet will see it, and it's worth explaining.
Gross payment status
With gross payment status contractors pay you without deductions and the company pays its own tax. To qualify, GOV.UK says HMRC looks for a record of paying tax and National Insurance on time, construction work in the UK, a business run through a bank account, and turnover over the last 12 months (ignoring VAT and materials) of at least £30,000 for each director or £100,000 for the whole company. If the company is controlled by 5 people or fewer, it needs £30,000 for each of them.
HMRC reviews gross payment status every year and you must be on time with tax returns and payments to keep it. If it's withdrawn, you have to wait a year before reapplying. That is a finance point as much as a tax one: losing gross status suddenly cuts what lands from every payment. GOV.UK also says that if HMRC gives you more time to pay, that will not affect your gross payment status, so if a tax bill is going to be late, talk to HMRC early (see VAT loans and Time to Pay).
How does the VAT domestic reverse charge change a groundworker's cash?
When you supply construction services to a VAT- and CIS-registered contractor that hasn't told you it's an end user or intermediary supplier, you don't charge it VAT: the contractor accounts for it instead. You still pay VAT on your own costs, such as plant, fuel and materials, so many subcontractors end up reclaiming VAT from HMRC rather than paying it.
GOV.UK's list of services covered by the domestic reverse charge includes site clearance, earth-moving, excavation, laying foundations, drainage works, roadworks and access works, the core of most groundworks packages. You must use it if you're VAT registered and your customer is VAT registered, the payment is reported under CIS, the services are standard or reduced rated, and the customer hasn't confirmed in writing that it's an end user or intermediary supplier. Your invoice must say the reverse charge applies and that the customer must account for the VAT.
Why it matters for cash flow
- Smaller payments in. GOV.UK's technical guide tells sub-contractors that customers won't be paying them VAT, which "will reduce the gross value of payments coming into your business", and to plan for that in day-to-day cash flow. Before the reverse charge, a sub could hold the VAT for a while before paying it over; now it never arrives.
- Repayment returns. You still pay VAT to your suppliers. The guide says you may make net repayment claims and can apply to move to monthly VAT returns through your online VAT account, which can get repayments back sooner.
- Buying plant on hire purchase. HMRC treats HP as a supply of goods, so VAT on the whole machine is usually due at the start (see hire purchase vs leasing). If your output VAT is low because of the reverse charge, that VAT comes back as a repayment, and the timing of your return decides how long you're out of pocket.
- Mixed customers. Work for homeowners, developers who are end users, or other non-CIS clients is invoiced with VAT in the normal way, so a firm with a mix of clients can swing between paying and reclaiming. Your accountant can tell you which applies to each customer.
When you talk to a lender about a VAT bill or a plant purchase, explain where you sit. A groundworker who is usually in repayment looks very different from one with a large VAT bill due.
What should you know before financing a muck-away or grab lorry?
A tipper or grab lorry is easy for a lender to understand, but it brings two licences with it. Over 3.5 tonnes you'll usually need a goods vehicle operator's licence, which needs financial standing. And in England a business that transports waste must register as a waste carrier with the Environment Agency.
Running your own wagons can cut tipping and haulage bills and keep jobs moving, but it adds a transport business to your groundworks business. Before you finance one, check:
The operator's licence
Goods vehicles over 3.5 tonnes used in connection with a business usually need an operator's licence. GOV.UK sets the financial standing you must have available: £3,100 for the first vehicle and £1,700 for each additional one on a restricted licence, and £8,000 and £4,500 on a standard licence. That's money available for the life of the licence, not a fee, and it's separate from any deposit. Which licence type fits depends on whether you're only moving your own goods or carrying for others for hire or reward, so check the GOV.UK guide before you apply. Our financial standing calculator works out the figure for your fleet.
Waste carrier registration (England)
GOV.UK says you must register if your business transports waste, buys, sells or disposes of it, or arranges for someone else to, and that you can get an unlimited fine if you don't. Registration is usually free if you only transport waste you produce yourself; otherwise it costs £191.02. You're told whether your registration is upper tier or lower tier: upper tier registrations must be renewed every 3 years (£130.25). Changing what your organisation does costs £49.62, and a change of legal structure, such as a sole trader becoming a limited company, needs a new registration. Wales, Scotland and Northern Ireland have their own processes.
Whether spoil from your own excavation counts as waste you produce, and which tier you need, depends on how the work is done: check with the Environment Agency before you start running muck-away for others.
What a lender will look at
- Your operator's licence (or application) and whether there's room for another vehicle on it.
- Whether the lorry will only serve your own sites, or also take outside haulage and muck-away work.
- Age, mileage and body type for used wagons (more in our HGV finance guide).
How can a groundworks firm plan finance around winter downtime?
Plan for the months when you can't dig before you sign up to new payments: time big purchases and agreement start dates around your season, keep enough cash for the slow months, and use hired plant for peaks. The weather also slows valuations, so the cash dip often arrives after the rain, not during it.
Groundworks is more exposed to the weather than most trades. Waterlogged ground stops excavation and slab work, cold snaps hold up concrete, while the plant, lorries, yard and core team still cost money. What's easy to miss is the delay: lost days in December show up as small applications in January and small payments in February or March, just as the spring start-ups need cash.
- Look at your own pattern. Line up the last two or three years' monthly receipts against your fixed commitments. That shows a lender (and you) the real low point.
- Choose start dates on purpose. Taking a new machine in October means paying for it all winter before it earns much. If you can, bring kit in for the spring programme.
- Hire for the peaks. Keep owned plant to the core fleet that works year-round and hire in the extra machines for summer, so you can off-hire when the weather turns.
- Ask about payment profiles. Some lenders can shape payments around a seasonal business. Availability depends on the lender and your figures.
- Watch your tax dates. Corporation tax for most companies is due 9 months and 1 day after the year end. If that lands in your quietest months, talk to your accountant about it early rather than borrowing at the last minute.
How does a lender read a groundworks company's accounts?
Beyond profit, a lender looks at who you work for and how concentrated that is, how much money is owed to you and how old it is, retentions and CIS deductions sitting on the balance sheet, existing finance on your plant, and whether your filings and tax are up to date. Explaining these before they ask makes a real difference.
Groundworks accounts can look strange to someone who doesn't know the trade. Good profit can sit alongside a tight bank balance, because the money is in valuations, retentions and CIS deductions. Things a lender or broker is likely to pick up on:
| What they see | What they're wondering | What helps |
|---|---|---|
| Most turnover from one or two main contractors | What happens if that contractor stops paying or stops giving you work? | A list of customers with how long you've worked for each, and the pipeline of packages |
| Large trade debtors or work in progress | Is this money collectable, or disputed measure? | An aged list of what's owed, with valuations and payment dates |
| Retentions owed | When will they be released, and are any at risk? | A retention schedule by job, with practical completion and end of defects dates |
| CIS deductions waiting to be recovered | Is cash stuck with HMRC? | Your CIS statements, EPS records and gross payment status position |
| Several plant finance agreements | Can the business carry another payment, especially in winter? | A plant list showing what's owned, what's financed and when each agreement ends |
| Late accounts, VAT or PAYE | Is the business under pressure, and is gross payment status at risk? | Up-to-date filings, or a clear explanation and any Time to Pay arrangement |
What to have ready
- Companies House number, years trading and director details for the lender's checks.
- The last one or two years' accounts, current management figures and recent business bank statements.
- Subcontract orders or letters of intent for your main live packages, and recent valuations.
- CIS payment and deduction statements, and your CIS status.
- A plant and vehicle list (owned and financed), and quotes for anything you want to buy.
- For wagons, your operator's licence details and waste carrier registration.
Being prepared doesn't decide the outcome, because each lender makes its own decision after its own checks, but it avoids the delays that lose you the machine or the start date.

Groundworks finance: frequently asked questions
What is groundworks finance?
Groundworks finance is business finance for groundworks and civils contractors. It can fund plant such as excavators and dumpers, muck-away and grab lorries, and the working capital needed between starting a package and being paid on a valuation. Finance is subject to status and the lender's checks.
Should I buy my own excavator or keep hiring?
Owning tends to suit machines that are on your jobs most of the year. Hiring suits occasional, specialist or single-contract machines, and it can be off-hired in bad weather, whereas finance payments continue. Look at your hire invoices for the past year to see which machines you hire almost continuously.
Can I get finance against applications for payment?
Some invoice finance providers fund construction debts, often against certified valuations, but many are cautious about applications, contra-charges and retentions because the final sum can change. Tell a broker exactly how you bill and how much is retention so they only approach providers that fund this kind of work.
Can a main contractor refuse to pay me until they get paid?
Under section 113 of the Housing Grants, Construction and Regeneration Act 1996, a clause making your payment conditional on the payer being paid by a third party is ineffective, unless that third party or someone further up the chain is insolvent. For a specific dispute, take legal advice.
Do CIS deductions come off the whole payment?
No. GOV.UK says contractors don't take CIS deductions from amounts on your invoice for VAT, materials you paid for directly, plant hired for the job, manufacturing or prefabricating materials, or consumables. The contractor may ask for evidence such as receipts.
How does a limited company get CIS deductions back?
Through its payroll. The company reports CIS deductions on its Employer Payment Summary and HMRC sets them against the PAYE it owes. Any excess carries forward within the tax year, and anything left after the tax year ends is claimed as a refund. Don't use the Corporation Tax return for this.
What turnover do I need for gross payment status?
GOV.UK says a company needs turnover over the last 12 months, ignoring VAT and materials, of at least £30,000 per director or £100,000 for the whole company. If it is controlled by 5 people or fewer, it needs £30,000 for each of them. HMRC also looks at whether tax has been paid on time.
Do I charge VAT to the main contractor?
Often not. If you're VAT registered and supply construction services such as excavation or drainage to a VAT- and CIS-registered contractor that hasn't said it's an end user or intermediary supplier, the domestic reverse charge applies and the contractor accounts for the VAT. Check each customer with your accountant.
Do I need a waste carrier registration for a muck-away lorry?
In England, GOV.UK says a business that transports waste must register as a waste carrier with the Environment Agency. It's usually free if you only carry waste you produce yourself; otherwise registration costs £191.02. Wales, Scotland and Northern Ireland have separate processes.
Does winter affect getting finance?
It affects your cash flow, which lenders look at. Showing your normal monthly pattern over a few years, and timing new agreements for the spring, helps a lender see that a winter dip is normal for your business. Some lenders can offer seasonal payment profiles, depending on your figures.
Do you lend money to groundworkers?
No. We are an independent guide and introducer, not a lender or a broker. With your consent we pass your enquiry to one specialist commercial finance broker from our partners. Our enquiry service is for limited companies and LLPs. We may be paid for the introduction.
