In short: A holding company is a limited company that owns the shares in one or more trading companies beneath it. For construction businesses, a group structure can keep risky contracts away from valuable plant, property and cash, make it easier to bring in investors or a second trade, and help with succession and sale. It also adds cost, admin and tax rules that can cancel out the benefits if the structure is set up for the wrong reasons. Whether it is worth it depends on your size, your risk and your plans.
Most construction businesses start as one limited company that wins the work, employs the team, owns the plant and holds every pound of retained profit. That works until one bad contract or one client failing owing you money puts everything in that company at risk. This guide explains the benefits and drawbacks of holding companies and group structures for construction limited companies, from groundworkers and roofers to main contractors and housebuilders. For wider support across the sector, see our construction accountants page.
A group is two or more companies under common ownership: a holding company, or parent, at the top and subsidiaries beneath it, each a separate limited company. Each has its own accounts, tax returns and debts. In construction, groups are usually built from three kinds of company.
Usually owned by the directors or their family, the holding company often does not trade. It owns the shares in the rest of the group and may also hold surplus cash or the freehold of the yard.
These do the work. A contractor might keep new build and maintenance in separate companies. A housebuilder might set up a new company for each development, so that the profit, finance and risk of each scheme stays in its own box.
An asset company owns plant, vehicles or property and hires or rents them to the trading companies. A common example is a groundworks firm moving its excavators, dumpers and rollers into a separate plant company, which then hires them back to the contracting company on commercial terms.
Defect claims long after completion, liquidated damages, disputed valuations, unpaid retentions and client insolvency are all part of construction. If everything sits in one company, a single problem can threaten the whole business. Separating trades or projects into different companies means a problem in one should not automatically drag down the others. An M&E contractor with a planned maintenance arm, for example, might keep the two apart so that a dispute on a large installation contract does not put its steady maintenance income at risk.
Holding plant and property away from the company that signs contracts and carries the trading risk can put them further out of reach of that company's creditors. In the same way, a housebuilder that has built up years of profit might move surplus cash up to the holding company rather than leave it exposed to the next development. How that cash moves matters for tax, and it changes how the holding company is treated, as we cover below.
Dividends paid by a UK subsidiary to its UK parent are usually exempt from corporation tax, so profit can often move up the group without an immediate tax charge. Where the ownership conditions are met, losses in one company may be set against profits in another through group relief, and some assets can be moved between group companies without triggering a gain at that point. Each has conditions, and getting them wrong can lose the relief or trigger a charge later. This is where specialist tax advisory support earns its keep.
A group lets someone into one part of the business without giving them a share of everything. A contractor launching a roofing division with an experienced roofer as a minority shareholder can put that division in its own subsidiary. A developer working with a landowner or funder on a single scheme can do the same. Some lenders also prefer to lend into a company that holds a single project or asset, which ties in with the options in our guide to funding options for construction companies.
Separating the trading business from the property and surplus cash can make a sale cleaner, because a buyer can acquire the trading company without taking on the yard or the savings. It can also let you hand one part to the next generation while keeping another. Selling a subsidiary from within a group can bring valuable reliefs, but the conditions are strict and can depend on the whole group. Structure is best settled years before a sale. Our business exit planning guide explains why, and our exit planning team can help you prepare.
Every company needs its own accounts, tax return, confirmation statement and records, and possibly its own payroll and VAT returns. For a smaller firm, the extra fees and time can outweigh the benefits, so it pays to have bookkeeping and management accounts that show each company and the group as a whole clearly.
Companies under common control are generally treated as associated for corporation tax, which means the profit limits that decide your rate are shared between them. Splitting one business into several companies can therefore push more profit into the main rate than you expected. A holding company that does nothing except pass dividends up to its shareholders may be ignored for this purpose, but one that keeps cash, owns property or has its own costs usually is not. That creates a direct trade off with the idea of keeping retained profits safe in the holding company.
Once work, plant, staff or premises are shared, money has to move between companies through management charges, plant hire, rent, recharged wages and loans. These need sensible levels and proper agreements. Poorly evidenced charges invite HMRC questions, can create VAT problems, and can weaken your separation, because an insolvency practitioner will look closely at money that left a failing company.
Group companies can often register together as a single VAT group, which can take VAT out of supplies between them. The catch is that every member becomes jointly liable for the group's VAT debts, which cuts across the whole point of ringfencing. Outside a VAT group, work supplied between your own companies may fall under the VAT domestic reverse charge. CIS raises similar questions. Each company has its own position as a contractor, a subcontractor or both, payments between group companies need checking against specific rules, and each company needs its own gross payment status if it wants to be paid gross. See our guide to what CIS means for construction businesses, or ask our VAT services team to review your position.
Lenders, landlords and main contractors often ask for a parent company or personal guarantee. Every guarantee you sign moves risk back to where you tried to move it from. A group structure only protects you as far as your guarantees allow.
A new trading company starts with no filed accounts, no credit history, and none of the accreditations, framework places or payment status the old company took years to earn. Main contractors running prequalification checks may treat it as a higher risk.
For many construction firms, one well run limited company is still the answer. A group is rarely worth it if you run a single trade with modest profits and few assets, if you would have to guarantee everything personally anyway, or if the main motive is saving tax, because the associated company rules and extra running costs often remove most of that saving. It earns its keep when there are real assets to protect, distinct activities, investors, or a sale in view. A group is also no substitute for sound contracts, the right insurance and firm credit control.
Most owners build a group around a company that is already trading, usually by exchanging their shares for shares in a new holding company, then sometimes moving plant or property into a new company. Done properly, this can often happen without an immediate tax bill. The order of the steps, advance clearance from HMRC, stamp taxes, the effect on your VAT and CIS registrations, lender consents and your existing contracts all need thinking through before anything is signed. Getting the sequence wrong is expensive and hard to undo.
Investing in rental property rather than building raises different questions, covered in our guide for London property businesses.
Before anything changes, our business advisory team looks at whether a group genuinely suits your size, risk and plans, and what it would cost to run. If it does, we work with you and your solicitor on the order of the steps, the tax position and the intercompany agreements, then look after the accounting, VAT, CIS and group reporting for every company so the structure keeps doing its job.
If you are weighing up a holding company, or have a group that grew without a plan, talk to our construction sector team. You can also learn more about how we support every kind of limited company. When you are ready, get started with Pulse and we will arrange a conversation with an adviser who knows construction.
A holding company is a limited company that owns the shares in one or more other companies, known as subsidiaries. In construction, the subsidiaries usually do the contracting work or own plant and property, while the holding company sits at the top of the group, often without trading itself.
Often not. If you run a single trade with modest profits and few assets, the extra cost, admin and tax rules usually outweigh the benefits. A group tends to make sense when you have valuable assets to protect, more than one distinct activity, investors or partners, or a sale or succession in view.
It can help. Keeping plant and property in a separate company from the one that signs contracts puts them further from that company's creditors. The protection is only as strong as the paperwork behind it, and any parent company or personal guarantees you have signed can bring the risk straight back.
It can. Companies under common control are usually associated for corporation tax, which means the profit limits that set your rate are shared between them. A holding company that only passes dividends up to its shareholders may be ignored, but one that keeps cash or owns assets usually counts.
Each company has its own VAT and CIS position. Companies can often form a VAT group, but every member then becomes jointly liable for its VAT debts. Supplies and payments between group companies need checking against the domestic reverse charge and CIS rules, and each company needs its own gross payment status if it wants to be paid gross.
Yes, and it is the most common way construction groups are formed. It usually involves exchanging your shares for shares in a new holding company. Done in the right order, with HMRC clearance where needed, it can often be done without an immediate tax charge, but it needs advice before anything is signed.
