Value engineering in refurbishment means getting the function your building needs for the lowest whole-life cost. It does not mean a cheaper specification. The RICS practice information on value management and value engineering frames value as function divided by cost. That gives you two ways to improve value: keep the function and reduce the cost, or keep the cost and get more function. Taking out scope or lowering performance is not on that list.
This guide is for developers, commercial landlords, and hotel and office owners refurbishing in London. It covers what value engineering is, why the term carries baggage after Grenfell, the red lines you should never cross, a worked example table, why timing before tender matters, a six-step process and the questions to put to your contractor.
Key takeaways
- Value = function / cost. Value engineering protects the function and questions the cost. It is a different thing from cutting the budget.
- Never value engineer fire safety, structural or compliance items. These are fixed requirements, not options on a menu.
- Value engineering works best before tender, when the design can still change. At the end of a tender it usually becomes a price negotiation.
- Judge every option on whole-life cost, not just the capital sum. A saving now that creates awkward maintenance later has not saved anything.
- Ask your contractor to show what function each change keeps, and to document the decision.
What value engineering means in a refurbishment
In a refurbishment, you are working with an existing structure, existing services and existing constraints. That makes the approach more useful than on a new build, because the unknowns are bigger and the room for smarter decisions is larger.
The method is simple to state. List what each element of the project has to do. Then ask whether there is a better way to deliver that function, in cost, programme, durability or maintenance terms. The RICS guidance describes this as a structured, team-based exercise run by competent people, not a one-off round of price reductions.
A few examples of what the function-first question looks like:
- A hotel corridor needs a floor finish that survives luggage trolleys and cleaning regimes. The function is durability and slip resistance, not a particular product.
- An office floor needs flexible power and data distribution. The function is adaptability for tenant changes, which may be delivered in more than one way.
- A mixed-use building needs a plant room that can be serviced safely. The function includes access, and that affects where plant is placed.
In each case, the question is what the element must do and what the cheapest reliable route to that outcome is over the life of the asset.
Why the term has a bad reputation after Grenfell
Let us deal with this directly. Since the Grenfell Tower fire, many people in construction hear “value engineering” and think of safety being traded for savings. That reaction is understandable. The RICS Construction Journal acknowledges that value management has attracted bad publicity when value engineering is used as a euphemism for cost-cutting. It adds that, done properly by competent, trained professionals, it can deliver real benefit.
The criticism is fair where the label has been used to swap specified products for cheaper ones late in a project, with the reasoning hidden. It is not a criticism of the discipline itself. The difference lies in four things:
- When it happens. Early design review is not the same as post-tender pressure.
- What is protected. Function and compliance are fixed. Only the means of delivering them is open to question.
- Who decides. Competent people with the right qualifications, not whoever is under the most price pressure.
- Whether it is recorded. Decisions are documented so they can be shown to a building control body, an insurer or a regulator.
If anyone proposes a change and cannot tell you what function it preserves, treat it as a cost cut and reject it.
The red line: what you never value engineer
Some items are not up for review. We set this line before any value engineering conversation starts, and we suggest you do the same in your brief.
Never value engineer:
- Fire safety. Compartmentation, fire stopping, fire doors, detection and alarm systems, means of escape, and the products that make up the fire strategy.
- Structural elements. Anything that carries load or provides stability, unless a qualified structural engineer is redesigning it as part of a documented design change.
- Compliance items. Anything required by the Building Regulations, gas, electrical and water hygiene standards, or accessibility requirements.
The legal context supports this. The Building Safety Act 2022 reshaped how building safety is regulated in England. The HSE’s Principles for Informed Clients document says clients are dutyholders under the Building Regulations 2010 as amended in 2023. It says they must appoint competent people and make sure decision-making is sound. In practice, that means you carry responsibility for what is specified and for the reasoning behind changes. It is a strong reason to keep cost-saving exercises away from anything safety-critical.
If you want a refresher on the obligations that sit behind this, our guides on why building safety regulations matter for UK property owners and fire safety obligations for landlords in London cover the practical side. For the technical standards a design has to meet, see our overview of what changes in the Building Regulations in 2026.
A note on fire engineering
Alternative approaches to fire safety do exist. The draft Approved Document B recognises that fire safety engineering can provide an alternative route in some complex buildings. That is a specialist design discipline carried out by qualified fire engineers and agreed through building control. It is not a cost-saving tool, and it should never be introduced by a contractor to reduce a tender price.
An illustrative worked example
The table below is illustrative only. The options are typical of the kind of questions asked on a commercial refurbishment, and no cost figures are attached because real numbers depend on the building, the market and the tender. It shows the logic: every row states the function that must be kept, and every row is judged on whole-life impact.
| Original specification | Alternative | Function kept | Whole-life impact |
|---|---|---|---|
| Bespoke joinery reception desk, made to drawing | Modular desk system from a standard range, finished to the same design intent | Brand presence, durability, accessible counter height | Lower lead time. Parts easy to replace, so repairs are cheaper over time. |
| Specialist imported floor tile in hotel corridors | Locally stocked tile with the same slip rating and wear class | Slip resistance, wear life, appearance | Shorter supply chain and easier like-for-like replacement. Check cleaning regime suits the new product. |
| Fully bespoke lighting fittings with proprietary drivers | Standard-range LED fittings with common, replaceable components | Lux levels, colour quality, controllability | Simpler maintenance and spares. Energy performance should match or improve. |
| Heavy masonry infill walls in an office floor | Lightweight partition system, designed and tested for the required performance | Acoustic separation, fire rating, layout flexibility | Faster install, easier reconfiguration for future tenants. Must be confirmed with the fire strategy and structural engineer. |
| Plant relocated to a new rooftop enclosure | Plant kept in existing plant room, with new access and attenuation | Capacity, serviceability, noise control | Less structural work and fewer new penetrations. Needs engineer sign-off on capacity. |
| Standard cavity fire barrier changed to a cheaper unlisted product | Rejected | Not applicable | Fire safety is a red line. No alternative is considered on cost grounds. |
The last row matters as much as the others. A good value engineering log records the options you refused and why.
Notice what the winning options have in common. They are not thinner or weaker. They come from changing how the function is delivered: standard components in place of bespoke ones, less structural intervention, or simpler maintenance. This matches what the Institution of Civil Engineers describes on the Boston Barrier scheme, where engineers cut carbon through design choices such as changes to foundations and use of prefabrication, not by lowering the performance of the barrier.
Why value engineering works best before tender
Timing decides whether this is a design discipline or a haggle. The RICS Construction Journal article makes the point that value engineering is most effective before tender. At that point you can still make big moves, such as re-siting plant or changing the foundation approach. Once tenders are in, contractors are mostly offering cost reductions within a fixed design, and the temptation to swap products grows.
There are practical reasons for this:
- Design is still fluid. Changing a layout on a drawing costs far less than changing it on site.
- Everyone prices the same thing. Bids are comparable because the VE decisions are already in the tender documents.
- Compliance is checked once. Changes are reviewed by the design team and, where needed, building control before the work is priced.
- Fewer late surprises. Early review, including 3D modelling for clash detection, reduces rework on site. The ICE case study on a bridge replacement over an operational railway describes a team culture that promoted value engineering and innovation, and met all of its deadlines.
That does not mean contractor ideas after award are worthless. Sometimes a contractor knows a better build method. Treat these as proposals that go through the same function test and the same documentation, not as price concessions.
Whole-life cost: the test every option must pass
Capital cost is only part of the picture. Whole-life costing looks at construction, maintenance, renewals and operation together. The RICS lifecycle costing guidance covers it for both new construction and refurbishment of existing assets.
The RICS journal piece also warns about a common hidden cost: an option that saves money now but leads to complex, non-standard maintenance. Such options often fail the whole-life test and should be dropped early.
For a hotel or office, the questions are practical:
- How often will this component be replaced, and can the replacement be sourced easily?
- Does it need specialist maintenance or a particular contractor?
- Will it disrupt trading or tenants when it fails?
- Does it affect energy use?
This is also where a contractor with a maintenance arm has an edge. People who will be called out when something fails tend to be honest about which products are a headache.
A 6-step value engineering process
This is how we suggest running it on a London refurbishment.
- Define the function and the red lines. Write down what each major element must achieve, and list the items that are excluded from VE: fire safety, structure and compliance.
- Survey and baseline. Understand the existing building: services, structure, condition and constraints. Refurbishment risk lives in the unknowns, so investigate before you decide.
- Generate options. Run a workshop with the client, designers, contractor and, where relevant, the facilities team. Each element gets alternatives for delivering the same function.
- Assess on whole-life cost and risk. Compare capital cost, maintenance, replacement cycle, programme impact and compliance. Reject anything that fails.
- Decide and document. Record the choice, the function kept, who approved it and any compliance checks. The log should be able to stand up to a review by building control or an insurer.
- Lock into the tender and monitor. Put the agreed design into the tender pack. During the build, any later change goes through the same loop, with photo records of progress and sign-offs.
Questions to ask your contractor
Use these at the pre-tender stage and again when anyone proposes a change.
- What function does this change keep, and how do you know?
- Does it touch fire safety, structure or any compliance item? If so, why is it on the table at all?
- What is the whole-life impact: maintenance, replacement cycle, spares and energy?
- Who has reviewed and approved it, and is that person competent for this type of decision?
- How will the decision be documented and shared with building control, insurers and your own team?
- What happens to the programme and to my tenants or guests?
- Which VE options did you reject, and why?
- Who will maintain this after handover, and have they been consulted?
- Are the trades coordinated under one contract, so there is a single point of accountability?
A contractor who welcomes these questions is usually one you can work with. One who gets defensive is telling you something.
Our perspective
We maintain and refurbish buildings, so we see both ends of a specification: the decision made at design stage and the call-out years later. That is why we treat value engineering as a design-stage discipline with firm limits.
Our view is simple. Function comes first. Cost follows from the best way of delivering it. Fire safety, structural and compliance items are not negotiable, and we say so before the first workshop. We would rather lose a tender than put a client’s building or occupants at risk to win it.
We also think the maintenance angle gets too little attention. Because we deliver planned and reactive maintenance as well as construction, we can flag early when a clever-looking option will cost you more every year it is in service. We bring all trades under one contract, give clients detailed photo progress reports and assign dedicated account managers to commercial and agency clients, so decisions are easy to trace.

FAQs
Is value engineering the same as cost cutting?
No. Value engineering looks at the function an element must deliver and finds the most efficient way to deliver it, judged over the life of the building. Cost cutting reduces the specification or scope and accepts lower performance. The RICS guidance is explicit that value engineering is not about downgrading performance below the required level.
When should value engineering take place?
Before tender, while the design can still change. That is when you can alter layouts, plant locations or construction methods and have every bidder price the same scheme. Reviews after award are still possible but are more limited and need the same documentation.
Can fire safety items ever be value engineered?
Not on cost grounds. Fire safety, structural and compliance items are red lines. Any alternative fire strategy has to come from a qualified fire engineer and be agreed through building control, as a design matter, not a saving. If your building is covered by the Building Safety Act 2022, take advice from your fire engineer or building control body before any change.
What is the difference between value engineering and whole-life costing?
Value engineering is the process of finding better ways to deliver required functions. Whole-life costing is the method used to compare those options by total cost over time, including maintenance, renewal and operation. The two work together: the first generates options and the second tests them.
Does value engineering suit smaller refurbishments?
Yes, in a lighter form. A short function review, a documented options log and a check on maintenance implications can be done on almost any project. Larger schemes justify a formal workshop, but the principle of asking what each element must do applies at every scale.
