Retailers planning a refurbishment face a frustrating problem. Ask three contractors what it costs, and you will get three completely different answers, each qualified with so many caveats that the figure is almost meaningless.
The reason costs vary so much is not that contractors are being evasive. Retail refurbishment covers an enormous range of work. A coat of paint and new flooring are a refurbishment. A full structural transformation is also a refurbishment. The word means different things depending on who is using it.
This guide breaks down retail refurbishment costs honestly by scope, so you can determine which category your project falls into and what a realistic budget looks like before you speak to a contractor.
Cosmetic refresh: £25 to £50 per sq ft
New decoration, updated lighting, replacement flooring, and shopfront signage. No structural works, no significant MEP changes, no joinery. This is the minimum intervention that meaningfully updates how a store looks and feels. Suitable for stores that are structurally sound and functionally adequate but visually dated.
Partial refurbishment: £50 to £90 per sq ft
One or two departments, a new ceiling system, improved lighting, updated fixtures, and targeted MEP upgrades. This is the most common scope for retailers refreshing specific areas of their estate. A convenience store upgrading its chilled display section, a fashion retailer modernising its fitting rooms and cash desk, or a food operator updating its customer-facing counter area all fall into this category.
Full refurbishment in a live trading store: £80 to £140 per sq ft
Complete replacement of all visible finishes and fixtures, ceiling systems, lighting, flooring, joinery, and shopfront, delivered in phases around trading hours. The store remains open throughout, which adds programme length and cost compared to a closed-site refurbishment. This scope is appropriate for retailers whose trading continuity is more valuable than building speed.
Full strip-out and rebuild on a closed site: £90 to £160 per sq ft
Full demolition of the existing fit-out, structural modifications where required, and complete reinstatement to a new layout and specification. The store closes for the duration of work. This delivers the best cost-efficiency per square foot for a given specification because the programme is unrestricted. It is the right approach when the existing fit-out is so outdated that partial retention adds complication rather than saving cost.
These figures are for construction works only. They exclude VAT, professional design fees, and any fixtures or fittings procured separately by the client.
Structural works
If your refurbishment involves removing or relocating walls, installing structural beams, or creating new openings, you move into a different cost category. Structural works require building control notification, structural engineering input, and significantly more site management than cosmetic or MEP-led refurbishment. They are worth doing when the existing layout genuinely cannot be made to work, but they are not a cost to take on lightly.
MEP replacement
Replacing electrical systems, upgrading HVAC, installing new data infrastructure, or adding extract ventilation in a food retail environment adds high cost. It is often unavoidable in older retail units where the existing services are at the end of life or inadequate for the retailer's equipment requirements. Old wiring, in particular, tends to surface as a cost that should have been in the budget from the start but was not.
Live trading delivery
Refurbishing a store while it is open costs more than a closed-site programme. Work happens primarily out of hours. Each section is reset to trading-ready condition every morning before the store opens. The programme is longer, and the site management requirement is higher.
Our experience delivering live trading refurbishments, including in supermarket environments where food safety compliance adds another layer of complexity, means this premium is not one we can justify. But it should be in your budget from the start. For a detailed look at how live trading refurbishments work in practice, read our guide on how to plan a retail refurbishment without closing your store.
Second-generation complications
Older retail units often have hidden issues that go unnoticed until strip-out begins. Asbestos in floor tiles, electrical systems that are below current standards, and structural modifications made without building control sign-off are all common findings. A 10-15 per cent contingency on the construction cost is not excessive for the refurbishment of a unit with no recent fit-out history.
Lease renewals are the most common trigger for retail refurbishment, and they are also the moment when landlords are most likely to offer a financial contribution to works.
Landlord contributions typically take one of two forms. The first is a rent-free period at the start of the new lease term. The second is a direct capital contribution to the fit-out works. Both are negotiable, and the amount available depends on the landlord's assessment of the tenant's value to the scheme, the state of the market, and the landlord's motivation to retain or attract a particular operator.
A few things worth knowing before you negotiate. The earlier you raise the refurbishment with your landlord, the more options you have. Raising it three months before lease expiry limits your negotiating position significantly. Raising it twelve months out gives you time to agree on the scope, agree on the contribution, and factor it properly into your budget.
Landlord contributions often come with conditions, including specific works that must be completed, a minimum lease term, or approval rights over the design and contractor. Make sure you understand those conditions before the contribution factors into your budget.
For managed retail environments, landlord approval of the design is usually required regardless of whether a contribution is being made. Building that approval process into your pre-construction programme rather than your construction programme avoids delays on site. Our retail refurbishment contractors page covers the landlord liaison process in more detail.
To make these figures tangible, here is what a mid-specification full refurbishment of a 3,000 sq ft high street retail unit looks like in 2026.
Strip-out and waste disposal: £8,000 to £12,000 First fix MEP: £18,000 to £28,000 Partitioning works: £6,000 to £10,000 Suspended ceiling: £12,000 to £18,000 Second fix MEP including lighting: £16,000 to £24,000 Flooring: £12,000 to £18,000 Shopfront and entrance: £8,000 to £15,000 Bespoke joinery and fixtures: £20,000 to £40,000 Decoration and finishes: £8,000 to £12,000 Signage: £5,000 to £10,000 Preliminaries and site management: £12,000 to £18,000
Total construction cost: £125,000 to £205,000
Add 10 to 15 per cent contingency, professional fees if applicable, and VAT. A realistic all-in budget for this scope and specification is £150,000 to £250,000, depending on specification choices and any site-specific complications.
Not every store needs a refurbishment, and not every refurbishment delivers the return it promises. Before committing to a budget, it is worth asking honestly whether the physical environment is the reason the store is underperforming, or whether the issue is the location.
A well-executed refurbishment in a store with genuinely declining footfall and a deteriorating retail mix around it will not solve a location problem. If the store is underperforming relative to similar locations in your estate and the location itself is sound, a refurbishment is worth serious consideration. If the footfall data points to a structural location issue, it is not.
We will tell you this honestly during the consultation. We would rather help you make the right decision than win a project that will not deliver the return you are expecting.
The starting point for an accurate cost plan is a site visit. We need to see the unit, understand your brief, and assess the existing condition before we can give you a figure that means anything.
At RCC, we provide line-by-line cost plans as standard with inclusions, exclusions, and assumptions clearly stated. If you are planning a retail refurbishment and want to understand what it will actually cost, contact our team, and we will arrange a site visit within the week.
