The Direct Answer

Office refurbishment costs are rising because businesses are asking more from their workplaces. Modern offices now need to support hybrid working, better staff experience, improved energy performance, stronger compliance, upgraded building services and more flexible layouts.

For London businesses, the priority should not be spending more on everything. The priority should be choosing the right works first.

The areas to review before committing budget are:

• building condition

• electrical capacity

• HVAC and ventilation

• fire doors and fire stopping

• lighting

• workplace layout

• meeting rooms

• staff welfare areas

• compliance risks

• phasing and disruption

• long-term maintenance

A smart office refurbishment is not the most expensive project. It is the one that solves the right problems in the right order.

Why This Topic Matters Right Now

Office refurbishment in London is no longer just about fresh paint, new flooring and updated furniture.

Businesses are under pressure to make workplaces more valuable.

Staff expect better spaces. Landlords need buildings to stay attractive. Tenants want offices that justify the commute. Facilities teams need safer, easier-to-maintain buildings. Energy performance and compliance are no longer background issues.

At the same time, fit-out and refurbishment costs are under pressure. Turner & Townsend has reported that demand for premium, highly amenitised office space and supply pressures have contributed to rising fit-out costs in major markets.

Overbury’s 2026 office fit-out outlook also highlights a shift towards smarter, more flexible and more responsible fit outs and refurbishments.

For BTS, this is a strong topic because it sits directly between search demand and commercial services: office refurbishment, fit out, mechanical and electrical works, fire safety, decoration, plumbing, roofing and planned maintenance.

The New Office Refurbishment Question

The old question was:

How can we make the office look better?

The better question now is:

Where should we invest so the office works better, lasts longer and avoids future cost?

That change matters.

A business can spend heavily on finishes and still end up with poor ventilation, awkward meeting rooms, weak lighting, outdated electrics or unresolved fire door issues.

The best refurbishment plans start with risk, function and building performance before moving into appearance.

Priority 1: Survey the Building Before Choosing the Finish

Many refurbishment budgets move because issues are discovered too late.

A project may begin as a design refresh, but once ceilings, floors, risers or plant areas are opened, the contractor may find problems with services, fire stopping, leaks, drainage or old installations.

Before deciding where to spend, check:

• ceiling voids

• floor condition

• electrical infrastructure

• lighting condition

• heating and cooling systems

• ventilation

• plumbing and drainage

• fire doors

• fire stopping

• water ingress

• roof or plant areas

• access restrictions

This gives the project a more realistic starting point.

Priority 2: Fix Building Services Before Cosmetic Upgrades

A modern office relies heavily on building services.

If the services are weak, the finished office will not perform properly.

Key areas include:

Electrical

Modern offices need power for desks, meeting rooms, screens, access control, charging points, kitchens, AV and flexible working areas.

Poor electrical planning can lead to:

• too few sockets

• visible trailing cables

• overloaded areas

• late alterations

• limited flexibility

• poor meeting room functionality

HVAC and Ventilation

Hybrid offices often include more meeting rooms, call rooms and enclosed spaces. These need suitable airflow and temperature control.

Poor ventilation can make spaces feel uncomfortable very quickly.

Plumbing and Drainage

Tea points, staff kitchens, WCs and welfare spaces all rely on practical plumbing and drainage.

If these are planned too late, layouts may need to change or costs may rise.

Priority 3: Treat Compliance as Part of the Budget, Not an Extra

Compliance is one of the biggest areas businesses underestimate during office refurbishment.

A project may affect:

• fire doors

• fire stopping

• escape routes

• emergency lighting

• electrical safety

• accessibility

• welfare facilities

• CDM duties

• fire risk assessment findings

If these are not considered early, they can become late-stage costs.

GOV.UK guidance on workplace fire safety states that the responsible person must carry out and regularly review a fire risk assessment and put in place appropriate fire safety measures.

The HSE also explains that commercial clients have duties under CDM 2015 when construction work is carried out, including making suitable arrangements for managing the project safely.

Priority 4: Spend on Layout Before Expensive Features

A poor layout makes even a high-spec refurbishment feel wrong.

Before investing in premium finishes, businesses should review whether the layout supports how the office is actually used.

Ask:

• are there enough meeting rooms?

• are there too many fixed desks?

• do staff have quiet space for calls?

• are breakout areas in the right place?

• is reception easy to use?

• are kitchens and tea points practical?

• are storage areas sufficient?

• do visitors understand where to go?

• can the office adapt if team numbers change?

The British Council for Offices has highlighted how office fit-out guidance now reflects hybrid working, wellbeing, smart technology and net zero considerations.

Priority 5: Upgrade Lighting Where It Improves Both Cost and Experience

Lighting is one of the most effective refurbishment upgrades because it affects appearance, energy use, comfort and staff experience.

Poor lighting can make an office feel tired even after decoration.

A lighting review should consider:

• LED upgrades

• task lighting

• meeting room lighting

• emergency lighting

• glare on screens

• natural light

• controls and zoning

• reception lighting

• kitchen and breakout lighting

• circulation lighting

For businesses managing costs, lighting is often a practical place to invest because it can improve the look and feel of the office while supporting energy efficiency.

Priority 6: Plan Around Disruption, Not Just Build Cost

The cheapest programme is not always the best programme.

In occupied offices, disruption has a cost too.

This may include:

• staff downtime

• reduced productivity

• client disruption

• access restrictions

• noisy works

• dust

• temporary relocations

• weekend or evening working

• longer handover periods

A refurbishment may cost more to deliver in phases, but it may reduce disruption to the business.

Before work begins, decide:

• will staff remain on site?

• can works be phased?

• are evenings or weekends needed?

• are noisy works restricted?

• do clients visit during the project?

• are neighbouring tenants affected?

• are temporary access routes required?

• how will updates be communicated?

Priority 7: Choose Materials That Reduce Future Maintenance

When budgets are tight, it can be tempting to choose cheaper finishes.

That is not always wrong, but it can become expensive if the materials wear quickly.

High-use areas need durable finishes, especially:

• reception areas

• corridors

• kitchens

• tea points

• meeting rooms

• toilets

• stairwells

• breakout areas

Think about:

• cleaning

• footfall

• moisture

• impact resistance

• repairability

• replacement cost

• long-term appearance

A finish that costs slightly more but lasts longer may be better value than a cheaper option that needs replacing quickly.

Priority 8: Review Fire Doors and Fire Stopping Before Decoration

Fire doors and fire stopping should not be left until the end.

A new office layout, new partitions or service alterations can affect compartmentation and escape routes.

Before decorating or finishing walls, check:

• fire door condition

• door closers

• smoke seals

• gaps around doors

• frames

• ironmongery

• service penetrations

• fire stopping around new works

• risers and voids

• compartment lines

The cost of opening up finished areas to correct fire stopping or door issues can be far higher than addressing them at the right stage.

What Businesses Should Not Cut First

When budgets come under pressure, avoid cutting the things that protect the building, people or programme.

Be cautious about cutting:

• surveys

• fire safety checks

• electrical upgrades

• ventilation improvements

• access planning

• proper waste management

• durable finishes in high-use areas

• handover documentation

• snagging allowance

• contractor coordination

These are often the areas that prevent future cost.

If savings are needed, start by reviewing specification choices, phasing, furniture selections, non-essential feature finishes and areas where the scope can be simplified without creating risk.

A Smarter Order for Office Refurbishment Budget Planning

Instead of starting with finishes, plan the budget in this order:

1. Safety and compliance

Fire safety, CDM duties, escape routes, fire doors, fire stopping and electrical safety.

2. Building condition

Leaks, defects, drainage issues, plant condition, fabric problems and hidden risks.

3. Building services

Electrical, HVAC, ventilation, plumbing, drainage, lighting and data.

4. Workplace function

Layout, meeting rooms, hybrid working, storage, reception, kitchens and staff areas.

5. Durability

Flooring, finishes, doors, decoration and high-traffic surfaces.

6. Visual upgrades

Branding, feature finishes, furniture enhancements and decorative details.

This order helps reduce the risk of spending heavily on appearance while leaving operational or compliance problems unresolved.

Signs Your Office Refurbishment Budget Needs Reviewing

Your budget may need a second look if:

• no building survey has been completed

• compliance has not been costed

• M&E works are only provisional

• the office will remain occupied but no phasing plan exists

• fire doors or fire stopping have not been reviewed

• the layout has changed several times

• furniture and power plans do not align

• landlord approvals are unclear

• finishes have been chosen before service requirements

• handover documents are not included

These are early warning signs that costs may shift later.
