Office LED Lighting Upgrades
London & the South East

Commercial LED installation for offices, retail units and managed workspaces. Fixed price. Minimal disruption. CHAS accredited.

Since September 2023, T8 fluorescent tubes can no longer be manufactured or imported into the UK. T5 tubes followed in February 2024. If your office still runs on fluorescent fittings, replacement parts are becoming harder to source — and eventually impossible. LED fittings also cut your lighting energy costs by 40–60% and typically pay back within two years. For most buildings it's not a question of whether to upgrade — it's when.

Is This You?

Three reasons offices
upgrade to LED

💡

Fluorescent Ban

Your fittings are failing and tubes aren't available

T8 and T5 fluorescent tubes are no longer being manufactured or imported. If you're replacing tubes every few months on an ageing system, you're on borrowed time. An LED upgrade removes the dependency entirely and gives you a fitting with a 50,000-hour rated lifespan.

EPC & MEES

Your EPC rating is under pressure before a letting or sale

LED lighting is one of the most cost-effective single interventions for improving a commercial EPC score. With MEES requiring EPC E as a minimum today and EPC C on the trajectory for 2027, lighting frequently sits at the top of landlords' improvement plans — high impact, fast to deliver, contained in cost.

See our MEES guide →

📈

Energy Cost Reduction

You want to cut your electricity bill and service charge

Lighting accounts for 20–40% of a typical office's electricity consumption. Switching from fluorescent to LED cuts that figure by 40–60%, with a payback period under two years in most cases. For landlords recovering costs through a service charge, the saving is directly visible to tenants — a genuine reason to upgrade.

The Service

End-to-end LED upgrades,
one contract

Renova Projects manages end-to-end LED lighting upgrades for commercial offices across London and the South East. That means we handle everything from the initial survey and specification through to installation, testing, certification and disposal of old fittings — under a single contract, with a single point of accountability.

We work directly with vetted electrical subcontractors, managed under our oversight. You deal with one team, one contract, one set of costs. No contractor management on your side.

What's included as standard

✓Free site survey and lighting design assessment
✓Fixed-price quotation — no day-rate exposure
✓Full luminaire supply and installation
✓Emergency lighting assessment and remediation where required
✓Removal and disposal of existing fluorescent or halogen fittings (compliant with WEEE regulations)
✓Circuit testing and commissioning
✓As-built drawings and electrical certification
✓EPC and MEES compliance documentation where applicable
✓Post-installation lux level verification

Works around your business hours. We regularly carry out LED upgrades in occupied offices — evenings, weekends, or phased floor-by-floor. If disruption is a concern, tell us when you enquire and we'll build the programme around your team.

The Business Case

Why offices are switching
to LED right now

Lighting typically accounts for 20–40% of an office's electricity consumption. Upgrading from older fluorescent or halogen fittings to LED can cut that figure significantly — and the payback period on a well-specified installation is usually well inside two years.

Rated lifespan of commercial LED fittings

Regulatory pressure is increasing

Commercial landlords and tenants are also being pushed by regulation. Since April 2023, the Minimum Energy Efficiency Standards (MEES) have required commercial properties to hold an EPC rating of at least E before they can be let. The trajectory is clear — EPC C is the target standard currently under consultation for 2027. Lighting is one of the most cost-effective ways to improve an EPC score.

If you manage or occupy a commercial building in London or the South East and your EPC rating is under pressure, a lighting upgrade should be one of the first things on your improvement plan. See our full guide to EPC C and MEES compliance for commercial landlords.

Better light, not just cheaper light

Modern LED office lighting also improves the working environment. Correct colour temperature and consistent lux levels reduce eye strain and fatigue — factors that matter when you're presenting a workspace to prospective tenants or trying to retain staff. It's a practical upgrade with a visible result, not just an efficiency box-tick.

Prices correct as of April 2026. Final cost depends on fitting count, circuit condition, access requirements and whether emergency lighting is in scope. We provide a fixed-price quote after a free site survey — no provisional sums, no hidden extras. Costs exclude VAT. Travel included within our standard coverage area (London, Kent, Surrey, Essex).

The Process

From survey to handover,
four steps

From first contact to completed installation, most office LED upgrades follow a consistent programme. Here's what to expect:

Free site survey — within 48 hours

We visit the site, assess your existing fittings, measure lux levels, check the condition of circuits and emergency lighting, and understand your working hours and operational constraints. There's no charge for this and no obligation to proceed.

Fixed-price quotation

Within three to five working days of the survey, you receive a fully itemised fixed-price quote. No provisional sums, no day-rate exposure. We specify the fittings, the programme and the cost. If you want alternatives or value engineering options, we'll provide them alongside.

Scheduled installation — around your hours

Once agreed, we schedule works to suit you. For occupied offices, we typically work evenings or weekends. Larger buildings are phased floor-by-floor so no area is out of action for more than one night. Our team leaves each area clean and fully operational before your staff arrive.

Testing, commissioning and handover

On completion, we carry out circuit testing, verify lux levels against specification, test emergency lighting function and produce all required certification. You receive a full handover pack including as-built drawings, test certificates and waste transfer documentation for the removed fittings.

Commercial Impact

More than a lighting job —
real commercial outcomes

A well-executed LED upgrade affects more than the electricity bill. For landlords, property managers and business occupiers, the downstream effects matter as much as the installation itself.

🏠

Asset value and EPC rating

LED lighting is one of the most cost-effective single interventions for improving a commercial EPC score. With MEES requiring EPC E as a minimum for lettable commercial property today — and EPC C on the trajectory for 2027 — landlords managing older stock need a clear improvement plan. Lighting frequently sits at or near the top of that list: high impact, fast to deliver, relatively contained in cost. We provide the documentation your energy assessor needs to record the improvement accurately.

📈

Service charge management

For multi-tenanted buildings, lighting energy and maintenance costs often flow through the service charge. Aging fluorescent installations generate recurring spend — tube replacements, ballast failures, emergency lighting call-outs. An LED upgrade cuts that ongoing maintenance burden significantly and reduces the service charge line items that tenants scrutinise at year-end reconciliation.

🌎

ESG and sustainability reporting

Occupiers with ESG commitments increasingly expect their premises to support — not undermine — their reporting. Measurable reductions in Scope 2 electricity consumption from lighting are straightforward to document. If your organisation is working towards a net zero target or reporting under SECR, a lighting upgrade is one of the more tangible, evidenceable actions available.

💼

Tenant attraction and retention

Light quality affects how a space feels and functions. Consistent lux levels, appropriate colour temperature and well-maintained emergency lighting are baseline expectations for prospective tenants and staff. An LED upgrade is visible, immediate and — done properly — makes a measurable difference to how an office presents. It is not a cosmetic exercise.

🔧

Avoiding reactive replacement costs

Fluorescent fittings don't fail cleanly. Tubes flicker before they go, ballasts degrade over time, and emergency lighting test failures create compliance exposure. Reactive repair across a large floor plate — call-out charges, time and materials, access arrangements — consistently costs more than a planned upgrade. Fixed price, on your terms, is the more defensible commercial decision.

Who We Help

Built for property managers,
landlords and FMs

Our commercial LED upgrade work covers a range of building types and client profiles across London and the South East:

Commercial landlords and property managers — improving EPC ratings ahead of MEES deadlines, or upgrading void units between tenancies to reduce service charge spend and improve asset value.
Office occupiers and facilities managers — reducing energy bills, improving working conditions, or meeting sustainability targets as part of ESG reporting requirements.
Fit-out and refurbishment projects — LED lighting is a standard component of our office refurbishment service. We can integrate it into a wider Cat A or Cat B project or handle it as a standalone package.
Planned preventative maintenance clients — if you have a PPM contract with us, LED upgrades can be incorporated into your scheduled programme rather than handled as a reactive project.
Dilapidations — where a schedule of dilapidations identifies lighting as a deficiency, we can remediate as part of a broader dilapidations project.

If you're not sure whether your situation fits, just get in touch. We'll tell you straight whether we're the right contractor for the job.

Coverage

London, Kent, Essex
and the M25 corridor

Renova Projects is based in Westerham, Kent — positioned to cover the full arc of commercial property from Central London through the M25 corridor and into the South East. We carry out LED lighting upgrades across the following areas:

London

We work across all London postcodes, covering City of London offices, Canary Wharf commercial buildings, West End managed workspaces and South, East and North London commercial properties. London accounts for the majority of our fit-out and refurbishment work — LED upgrades are regularly delivered as standalone projects or as part of wider office refurbishments.

City of London Canary Wharf West End South London East London North London Southwark Waterloo Victoria Farringdon

Kent

Our head office is in Westerham, Kent, and we have strong coverage across the county — from Dartford and Gravesend in the north, through Sevenoaks, Tonbridge and Maidstone, to Ashford and the Channel Tunnel corridor. Kent's commercial property market includes a significant volume of industrial and logistics stock alongside traditional office space, much of which is still running legacy lighting installations.

Dartford Gravesend Sevenoaks Tonbridge Kings Hill Maidstone Tunbridge Wells Ashford Westerham Chatham Canterbury

Essex and the M25 corridor

We cover Essex commercial properties from the Thames Gateway eastward — Thurrock, Basildon, Chelmsford and Brentwood — as well as the M25 business parks at Lakeside, Chafford Hundred and the wider A13 corridor. This area contains a large stock of out-of-town and business park office space, much of which was developed in the 1990s and is overdue for lighting infrastructure renewal.

Thurrock Basildon Chelmsford Brentwood Romford Lakeside Grays Harlow

Surrey, Sussex and Hertfordshire

We also cover Surrey commercial property — Guildford, Croydon, Reigate and Redhill — Sussex, and Hertfordshire, particularly where clients have buildings in multiple locations across the South East under a single property management arrangement.

Croydon Guildford Reigate Redhill Crawley Brighton Watford St Albans

If your building is outside these areas but within the wider South East, contact us to confirm coverage — we'll tell you before you invest time in an enquiry.

The Comparison

LED versus fluorescent —
what changes

Most London offices still running T8 or T5 fluorescent strip lighting are operating with fittings that are 15–25 years old. The comparison below covers the main factors clients ask about before committing to an upgrade:

Factor	Fluorescent (T8/T5)	LED panel / batten
Energy consumption	36–58W per fitting	18–40W equivalent output
Rated lifespan	8,000–15,000 hours	40,000–50,000 hours
Maintenance requirement	Tube replacements every 2–3 yrs	Minimal — no tube changes
Light quality	Variable, colour shift over time	Consistent, tunable CCT
Emergency lighting	Separate gear required	Self-test modules available
EPC contribution	Poor	Significant improvement
Disposal on replacement	WEEE / mercury tube handling	Standard recycling

For most office environments, the upgrade pays back through energy savings alone within 18–24 months. Factor in reduced maintenance and EPC benefit and the case is straightforward.

Why Renova

One team, one contract,
full accountability

There's no shortage of electrical contractors offering LED installation. The question is who manages the process, takes accountability for the outcome, and doesn't leave you chasing trades when something needs sorting. Here's what's different about working with Renova:

👥

Single contract, single point of contact

We manage vetted electrical subcontractors directly, under our oversight and on our contract. You don't deal with multiple parties. You don't manage access, sequencing or quality sign-off. You have one number to call and one company responsible for delivery — from survey to handover pack. That's the model across everything we do, not just lighting.

🏛

Commercial construction background — not domestic electrical

Renova's background is commercial fit-out and refurbishment. We understand occupied buildings, phased programmes, landlord-tenant relationships and the documentation requirements that commercial property transactions generate. An LED upgrade from us comes with as-built drawings, circuit test certificates, waste transfer documents and MEES-supporting records as standard — because that's what our clients' asset managers and managing agents need to see.

💰

Fixed price. No provisional sums.

We survey the site before we quote. We quote what we find, not what we guess. The price you agree is the price you pay — unless you change the scope. We've worked in enough commercial buildings to know where the variables are and how to price them properly upfront, rather than flagging them as extras during delivery.

🕐

Works that don't disrupt your tenants or staff

Out-of-hours delivery is standard practice for us, not a premium add-on. We've carried out LED upgrade programmes in occupied City offices, operational warehouses and multi-tenanted managed buildings across London and Kent without a single tenant complaint raised through a managing agent. That record matters when you're making the case for capital works to a difficult board or tenancy.

✅

CHAS accredited and fully compliant

We hold CHAS accreditation and NAFDI membership. Full insurance documentation, method statements and risk assessments are provided as part of our standard pre-construction pack — without you having to chase. For procurement by larger managing agents or institutional landlords, our compliance file is ready to submit.

📍

Based in Kent, active across London and the South East

We're not a national contractor parachuting teams in from elsewhere. We're based in Westerham, Kent, operating across a geography we know — London, the M25 corridor, Essex and the South East. Response times are fast, site visits are straightforward to arrange, and our subcontractor network is local and vetted rather than sourced through a framework at distance.

FAQs

Common questions
answered

How long does an office LED upgrade take? ▼

For a single-floor office of 2,000–5,000 sq ft, installation typically takes one to two nights of out-of-hours working. Larger buildings are phased — most multi-floor offices are completed within a week of commencing works, with each floor available the following morning.

Do you work out of hours? ▼

Yes. Out-of-hours working is standard for occupied office buildings. We schedule around your operating hours — whether that means evenings, overnight or weekends. This is factored into the quote upfront, not added as an afterthought.

Will the work affect our internet, server rooms or IT infrastructure? ▼

LED lighting installation does not typically affect data infrastructure. We carry out a desk survey before works begin and flag anything that requires specific coordination. Server rooms and comms rooms are worked around or scheduled for separate access if needed.

What happens to the old fittings? ▼

We remove and dispose of all existing fittings as part of the contract. Fluorescent tubes contain mercury and are classified as hazardous waste — we handle disposal through a licensed contractor and provide waste transfer documentation as part of your handover pack.

Can you improve our EPC rating at the same time? ▼

LED lighting is one of the most effective interventions for improving a commercial EPC score. We provide the documentation your assessor needs — metered loads, fitting specifications and lux level data. If you need a full EPC C compliance review, see our EPC and MEES compliance service.

Do you provide a guarantee on the installation? ▼

Yes. All installation work is guaranteed and we specify fittings from manufacturers offering a minimum five-year product warranty. Specific warranty terms are confirmed in your quotation.

Are you CHAS accredited? ▼

Yes. Renova Projects holds CHAS accreditation and is registered with NAFDI. Full insurance and compliance documentation is available on request — typically required for procurement by larger landlords or managing agents.

How much does a commercial LED upgrade cost? ▼

Cost depends on building size, number of fittings, existing circuit condition and access requirements. Small offices (up to 25 fittings) typically fall between £1,500 and £4,000; medium floors (25–75 fittings) between £4,000 and £10,000; larger buildings from £10,000 upward. See our full cost guide above for a breakdown by project scale. We provide fixed-price quotes after a free site survey — no provisional sums, no hidden extras. Prices correct as of April 2026.
