Working live

Phasing, out of hours, and working around your trade.

Most commercial fit outs cannot stop the business operating. Tenants need to keep trading. Customers need to keep walking through the door. Staff need to keep working. The programme has to flex around all of it.

Nationserv is used to phased delivery in live commercial environments. Out of hours working, weekend programmes, isolating sections of the building, dust and noise control, and tight coordination with FM teams, building managers and security. The build sequenced around your operation, not the other way round.

How we work

From first call to opening day.

A clear, four stage path from initial enquiry through to handover. The same surveyor led discipline that runs every insurance repair reinstatement, applied to commercial fit out.

Stage one

Brief and survey

A senior surveyor attends, captures the brief, completes a dilapidation assessment where required, and sets out the planning, licensing and feasibility position.

Stage two

Specification and quote

A fixed line by line specification with materials, trades, programme, phasing plan and a defined opening date. Transparent pricing.

Stage three

Build and project management

Nationserv teams across every core trade, coordinated by a single project lead. Weekly updates, controlled phasing, out of hours working as required.

Stage four

Snagging and handover

Formal snagging, Building Control sign off, full operation and maintenance manuals, and a documented handover pack. Aftercare available beyond completion.

Common questions

What operators ask us.

Can Nationserv work around our live trading hours?

Yes. Phased delivery, out of hours working, weekend programmes and isolated working sections are standard for our commercial fit out projects. The programme is sequenced around your trading operation, with dust and noise control, separate site protocols and tight coordination with FM teams, building managers and security.

What sectors do you cover?

Hospitality, retail, heritage commercial and industrial. We have delivered everything from a £500,000 luxury bar in Milton Keynes through to complex heritage reinstatement at the Royal Society of Medicine in London, retail showroom fit out, and warehouse and industrial unit conversion.

How quickly can you mobilise?

For most enquiries we can be on site for a survey within five working days, and have a fixed line by line specification with you within two weeks of brief. Build mobilisation depends on the programme and any planning, licensing or landlord consent required.

Do you handle Building Control and CDM compliance?

Yes. Nationserv manages CDM 2015, Building Safety Act, Fire Safety and DDA accessibility compliance as standard. Risk assessments, method statements, full operation and maintenance manuals and Building Control sign off are included in every commercial project.

Can you work to our interior designer's drawings?

Yes. We are happy to deliver fit outs designed by your existing interior design team, and we work with several trusted design partners if you do not have one. Either way, the build runs under one Nationserv project lead from first site visit through to handover.

Do you work outside Hertfordshire?

Yes. Nationserv covers 12 UK regions: Hertfordshire, Bedfordshire, Buckinghamshire, Cambridgeshire, Northamptonshire, Oxfordshire, London, Essex, Peterborough, Norfolk, Suffolk and Cornwall. The head office is in Stevenage and commercial work runs across the home counties and London.
