Horticulture finance for nurseries, glasshouse and fruit growers

Not on the growing land and growing buildings, in England, provided the site is used for agriculture in the rating sense. Business rates law counts market gardens and nursery grounds as agricultural land, and a glasshouse or polytunnel is exempt when it is occupied together with that land and used solely in connection with growing. Parliament restated the exemption for nursery grounds in 2018, after a court ruling had led the Valuation Office Agency to start valuing some nurseries, and growers who had been charged from 1 April 2015 could ask for refunds. The exemption follows the activity rather than the address, so it is worth checking each building on a mixed site before a lender's valuer or a buyer does.

Does a garden centre or farm shop on a nursery pay business rates?

Yes, as a rule. Selling to the public is retail, not an agricultural operation, so a garden centre where plants are displayed and sold to visitors is rateable even when the stock was grown next door, and the 2018 change did not extend to garden centres. A small farm shop can sometimes be treated as too minor to rate, but that is a judgement for the Valuation Office Agency rather than an entitlement. A packhouse can also lose the exemption if it handles substantial volumes of produce bought in from other growers. Lenders look at the rates bill in the accounts, so a grower adding a shop or café builds the extra cost into the forecast that supports the borrowing.

• Growing land. Market garden or nursery ground occupied with the buildings.
• Growing buildings. Glasshouses and polytunnels used solely for growing.
• Retail space. Garden centre, shop or café areas open to the public.
• Bought in produce. How much the packhouse handles for other growers.

The Valuation Office Agency rating manual explains the agricultural premises exemption. Our pages on garden centre finance and farm diversification finance cover the retail side of a growing business. Instant Quotes shows the panel lenders that could fund growing structures and equipment.

Often, yes, unless the holding can use agricultural permitted development. Large commercial polytunnels are generally treated as buildings for planning purposes because of their size, how long they stay in place and how firmly they are fixed to the ground, and the courts have upheld that approach. Councils look at each scheme on its facts, and some with a lot of soft fruit growing have published their own guidance on tunnels. A grower planning a large block of tunnels therefore checks the planning position before ordering the frames, because a lender funding the structures, or taking the land as security, will ask for the permission or the council's decision on prior approval.

How big can an agricultural building be without planning permission?

In England, up to 1,500 square metres of ground area on an agricultural unit of 5 hectares or more, under Class A of the agricultural permitted development rights. The limit rose from 1,000 square metres in May 2024. The building must be reasonably necessary for agriculture on that unit, and the grower first asks the council to decide whether it wants to approve the siting, design and appearance. A unit under 5 hectares cannot put up new buildings this way and can only extend existing ones, now by up to 25% of the original cubic content. Height limits, distance from roads, protected buildings and designated land all restrict what is allowed, so glasshouse and tunnel schemes near a listed building or ancient woodland need particular care.

• Holding size. Whether the agricultural unit is 5 hectares or more.
• Prior approval. The council's decision on siting, design and appearance.
• Ground area. Total area of the new building within the 1,500 square metre limit.
• Nearby constraints. Listed buildings, ancient woodland and other designations.

The order that raised the limits is on legislation.gov.uk as SI 2024/579. Growing structures can be funded through hire purchase, and our agricultural land purchase guide covers buying more ground to grow on. Instant Quotes lists panel lenders that consider polytunnels and glasshouses.

Horticultural cash flow problems tend to come from one of a handful of places:

• The spring build. An ornamentals nursery spends through winter on potting, compost, containers, labels and heating, then sells most of its year in a few spring weeks to garden centres and retailers. A cold, wet April shifts sales later and stock that misses its window may be discounted or binned.
• Stock that takes years to grow. Shrubs, trees and perennials can sit on the nursery for one to three seasons. That work in progress is real value, but living plants are difficult for a lender to take as security. Vines face a longer version of the same wait, covered in our page on vineyard finance.
• Energy. Heated glasshouses and mushroom farms are among the most energy-intensive rural businesses. A jump in gas or electricity prices can wipe out a year's margin, and capital spent on heat pumps, biomass, thermal screens or combined heat and power is often the answer.
• Labour. Picking, potting and packing are labour-heavy. Soft fruit and some protected crops rely on seasonal workers recruited through the Seasonal Worker visa route, with recruitment and accommodation costs paid before the season's income arrives.
• Retail payment terms. Supermarkets, multiple retailers and large garden centre groups pay on their own terms, and promotions, rejected loads and retrospective deductions affect what actually arrives.

A hypothetical example with round figures and no rates. A strawberry grower supplying a retail packer adds four hectares of table-top production under Spanish tunnels at a cost of around £400,000 including irrigation. Tunnels, table-tops and fertigation go on asset finance over a term matched to their useful life, with payments weighted to the picking months. A separate facility covers plants, substrate and the extra seasonal workers until the first sales are paid. The lender is shown the packer's programme for the new area before the finance is approved.

The concentration that makes a grower efficient also makes it fragile: losing one retail programme can remove most of the year's income while finance payments carry on. Fixed equipment and glasshouses are only as valuable as the business using them, so lenders often want additional security or personal guarantees. Borrowing of £25,000 or less by sole traders and small partnerships can be regulated consumer credit, which brings additional protections. Before taking on debt, consider whether a customer will co-fund capital items as part of a longer supply agreement, whether government grants for productivity or energy efficiency are open, and whether some propagation could be bought in rather than grown.
