Renovation Project Manager: What They Do and Who to Hire
A renovation project manager is the person who runs your build on your behalf. They turn a brief into a scope, a budget and a programme, make sure approvals are in place, coordinate the trades, and hand you a finished home with the paperwork. You can hire one independently, or you can choose a contractor that provides project management in-house. Which is right depends on the size of your project and how much of the coordination you want to carry yourself.
This guide covers what the role involves, what it costs, what to ask before you appoint anyone, and the London-specific issues that catch homeowners out.
TL;DR
A good manager covers feasibility, approvals, budget, programme, contractor management, quality, snagging and handover, not just scheduling.
Independent managers typically charge 15% to 20% of renovation spend, or £100 to £200 an hour, according to one 2026 cost guide. Your quote may differ.
There is no single legally required qualification. Relevant experience on comparable London refurbishments matters more than a title.
In London, check planning, building regulations, party walls and lease consent before work starts. They are separate processes.
For many homeowners, a contractor with director-led, in-house project management gives one point of accountability instead of two contracts.

What a renovation project manager actually does
The job is wider than keeping a calendar. RICS describes project management as organising design, planning, procurement and construction while keeping appropriate procedures and records. For a homeowner, that breaks down into a handful of practical responsibilities.
Feasibility and brief. Turning “we want a bigger kitchen” into a written scope that can be priced and built.
Approvals. Working out whether you need planning permission, building regulations approval, a party wall notice or landlord consent, and in what order.
Budget. Setting a baseline, tracking spend against it, and controlling variations.
Programme. Sequencing trades so the plumber, electrician, plasterer and joiner are not waiting on each other.
Contractor management. Appointing under a clear contract and checking work against the specification.
Quality, snagging and handover. Inspecting stages, listing defects, and collecting certificates and completion documents.
What you should receive from this work is concrete: a defined scope, a baseline budget, a programme, a decision log, a variation process, regular site reports and completion documentation. If a proposal cannot tell you which of these you will get, keep asking.
Project manager, builder or contractor: what is the difference?
The terms overlap, which causes confusion. A builder or contractor carries out the work. An independent project manager is appointed by you to oversee the work and, usually, the contractor. A contractor offering project management supplies both: the person coordinating the job and the people doing it.
Independent project manager | Contractor with in-house project management | |
Appointed by | You, separately from the builder | You, under one contract |
Carries out the work | No | Yes |
Independence from the builder | High | Lower, but accountability is single-point |
Fees | Separate fee on top of build cost | Built into an itemised quotation |
Best for | Large, complex or multi-contractor projects | Most residential refurbishments, extensions and lofts |
Neither model is automatically better. An independent manager adds a second pair of eyes on a complex build. A single accountable contractor removes the gap between “managing” and “doing”, where responsibility can blur when something goes wrong.
What a renovation project manager costs in the UK
Independent managers usually charge either a percentage of the build or a fixed or hourly fee. One 2026 guide from a trades marketplace puts the typical charge at 15% to 20% of total spend, averaging 17.5%. The same guide quotes £5,000 to £7,000 for a pre-construction planning package, £1,000 to £3,500 a month for on-site support, and £100 to £200 an hour.
Treat these as a guide, not a quote. Fees vary with location, project size and how much of the job the manager covers. Ask every candidate exactly what is included, how many site visits that means, and what happens if the programme overruns.
With a contractor that includes project management, you do not pay a separate manager’s fee. The management sits within the itemised quotation. At Tenen Ltd, quotations follow a site survey and are itemised, so you can see what you are paying for before you sign.
Do they need a qualification?
No single qualification is legally required to manage a renovation. The Association for Project Management offers the PFQ for foundational knowledge and the PMQ for broader capability, with Chartered Project Professional status as a higher route. These show a person has studied the discipline. They do not certify that someone is right for a Victorian terrace in Fulham.
RICS takes a similar view of suitability. Its guidance on appointing a manager says to look for relevant knowledge, construction experience, leadership, communication, record-keeping, programming and risk-management skills, alongside an appropriate educational or professional qualification.
In practice, ask for three things:
Examples of comparable projects, ideally in your borough or a similar period of property.
A named person who will be responsible for your job, and how often they will be on site.
Their reporting, change-control and risk process, in writing, before you sign.
That last point matters. RICS’s central message is that the role is mainly about people: authority, communication and calm problem-solving. A technically strong manager who rarely communicates still creates risk.
The London issues a good manager catches early
Most expensive surprises on London projects are not building problems. They are approval problems that surface late.
Planning, building regulations and party walls are separate
Passing one does not satisfy the others. Council guidance confirms that planning permission and building regulations approval are separate, and neither replaces Party Wall Act compliance. Building regulations can apply to extensions, structural alterations, plumbing, boilers, electrical installations and insulation. Ealing Council warns that work done without a required building regulations application can affect a future sale, mortgage and insurance.
If your home shares a wall with a neighbour, read our guide to party wall agreements and the notice periods that apply in London before you fix a start date.
Leasehold consent
If you own a flat, check the lease first. Camden Council’s guidance says leaseholders must obtain written consent before alterations or improvements, with examples including replacing a bathroom or kitchen, electrical work, plumbing, flooring and windows. More extensive changes may need a deed of variation, building control, planning permission or a party wall award. Other landlords have their own rules, so the route depends on your lease. A manager should verify this before quoting, not after.
Period homes and retrofit
Many West London homes are older properties where damp, ventilation and thermal bridging interact. RICS retrofit guidance supports an evidence-led approach: understand the building and site conditions before choosing measures. Adding insulation to a damp solid-wall house without that assessment can make things worse. If your project includes energy upgrades, ask whether the manager understands the retrofit standards, including PAS 2035:2023 and PAS 2030:2023.
How to manage a house renovation, step by step
Whether you hire a manager, a contractor or do it yourself, the sequence is the same.
Write the brief. Rooms, priorities, budget ceiling, must-haves and nice-to-haves.
Run a feasibility review. Structure, services, tenure, conservation or listed status, and neighbours.
Confirm permissions. Planning, building control, party wall notices and landlord consent where relevant. Councils such as Hackney encourage contacting building control early and explain staged inspections.
Develop drawings, specification, budget and programme. The more precise the specification, the fewer variations later.
Appoint the contractor under a clear contract. Fixed, itemised pricing makes comparison honest.
Monitor the build. Progress, payments against completed work, quality, variations and inspections.
Snag and hand over. Defect list, certificates, warranties and operating instructions.
Our homeowner’s checklist for hiring contractors in London covers step five in more detail, and common renovation mistakes is worth reading before you finalise the brief.
How to compare project management options
Ignore generic online rankings. A list cannot tell you who suits a two-storey rear extension in Chiswick. Compare on the things that decide how your project will actually run:
Residential renovation experience, with references for comparable London projects.
Transparent scope and fees, so you know what is and is not included.
Insurance, and what it covers. Our guide to what renovation insurance means for your project explains the questions to ask.
Contract administration capability and knowledge of approvals.
Site-presence arrangements: who is there, and how often.
Reporting: what you receive, and when.
Independence, where it matters to you.
RICS stresses that suitability to the particular project is what counts, and that is the right lens for any shortlist.
Our perspective: why we run projects under director oversight
Since 2006 we have refurbished homes across Fulham, Chelsea, Kensington, Chiswick, Hammersmith and Notting Hill. The pattern we see is consistent: projects go well when one accountable person understands both the design intent and the practical sequence on site.
That is why we manage projects in-house with director oversight. We do not rely on chains of subcontractors, so the person who prices your job is close to the people who build it. Quotes are fixed and itemised after a site survey, so there are no hidden costs or surprises in the numbers you sign. We aim to make a site visit quickly once you get in touch, because most of the important decisions are made before the first day of work.
We also think homeowners are right to be cautious. Ask any contractor, us included, to show you the programme, the variation process and the warranty cover in writing. If you have a very large or unusually complex build and want independent oversight on top, that is a reasonable choice, and we are happy to work alongside one.

When in-house project management is enough
For most residential projects, a single contractor with its own project management works well:
A full property refurbishment where several trades must be sequenced.
A rear, side or wrap-around extension.
A loft conversion, where structure, stairs, electrics and finishes all depend on each other.
A kitchen or bathroom renovation, where plumbing, electrical and joinery overlap.
In each case, one team coordinating its own trades means fewer handovers and a clearer line of responsibility. If you are planning bigger structural changes, our internal remodelling guide for London homeowners shows how layout decisions affect cost and sequence.

FAQ
How much does a renovation project manager cost in the UK?
One 2026 cost guide gives 15% to 20% of total renovation spend, or £100 to £200 an hour. Fixed pre-construction packages are quoted separately. Always confirm what the fee covers and how many site visits are included.
Do I need a project manager for a house renovation?
Not legally. A small, single-trade job is often manageable yourself. For anything involving several trades, structural work or approvals, someone must coordinate the programme, budget and permissions. That person can be an independent manager or a contractor’s in-house project manager.
What qualifications should a project manager have?
There is no single mandatory qualification. APM’s PFQ and PMQ and Chartered status are recognised routes. Documented experience on comparable refurbishments is usually more useful than a title, so ask for references and examples.
What is the difference between a project manager and a builder?
A builder carries out the construction. An independent project manager oversees planning, budget, programme and quality on your behalf. Some contractors offer both under one contract, which gives you one accountable point of contact.
