Contract Administration in London
A building contract only protects you if someone administers it properly. Wimbledon Surveyors acts as contract administrator on JCT and similar contracts across London, certifying payments, managing change and holding both parties to the bargain. Talk to a contract administrator.
What a Contract Administrator Does
The CA issues instructions, values work fairly, certifies payments and completion, and adjudicates day-to-day questions between employer and contractor — impartially, as the contract requires.
Specification and Tender
We prepare the specification and contract documents, invite tenders from vetted contractors and report on the returns, so the contract starts on solid ground.
Valuations and Certificates
Interim certificates release money only for work properly done. Our valuations protect employers from over-payment and give contractors prompt certainty.
Practical Completion and Defects
We certify practical completion, manage the rectification period, and settle the final account — closing the project cleanly instead of leaving loose ends that become disputes.

Contract Administration for Building Projects
A building contract only protects you if someone runs it properly. The contract administrator (CA) is the professional named in the contract to do exactly that: issuing instructions, valuing work, certifying payments, monitoring the programme and certifying completion. We act as contract administrator on JCT contracts across London and Essex — for homeowners on renovations and extensions, and for landlords, businesses and institutions on refurbishments and fit-outs — bringing impartial, experienced administration that keeps projects fair, documented and enforceable.
What the Contract Administrator Does
- Payment certificates — valuing work actually done before you pay, and certifying interim payments in line with the contract.
- Instructions and variations — issuing changes formally, priced and recorded, so the final account has no surprises.
- Extensions of time — assessing delay claims against the contract’s rules, protecting your right to liquidated damages.
- Practical completion — certifying completion only when it is genuinely reached, which triggers key contractual consequences.
- Defects and retention — administering the rectification period and releasing retention only when defects are made good.
- Final account — concluding the true contract sum with all variations and claims resolved.
Why Impartial Administration Protects Both Sides
The CA acts fairly between employer and contractor when certifying — that impartiality is what makes certificates enforceable and disputes rare. Contractors take a properly administered contract seriously: claims are documented rather than invented, and payment disputes are settled by valuation rather than standoff. For clients, the discipline of formal instructions and certificates converts the contract from paper to protection.
JCT Contracts for Every Scale
We administer the JCT Homeowner and Minor Works forms for domestic projects, and the Intermediate and Standard forms for larger works — advising at the outset which form fits your project and completing the contract particulars correctly. On design and build projects, the equivalent client-side role is the employer’s agent, which we also provide. The worst outcome we see is the “handshake plus deposit” project with no contract at all — if that is where you are heading, involve us before you sign anything and we will set the contract up as part of the appointment, alongside full project management where needed.
When Projects Go Wrong
Because every instruction, valuation and certificate is documented, a professionally administered contract is also your best protection if relationships break down. We prepare the paperwork for liquidated damages, termination where justified, and adjudication or litigation support — with our expert witness surveyors providing independent evidence where proceedings follow. Our site inspection service pairs naturally with the CA role, giving certificates a foundation of first-hand quality knowledge.
Frequently Asked Questions
The professional named in the building contract to run it: issuing instructions, valuing and certifying payments, assessing delay claims, certifying completion and administering defects and retention. The CA acts impartially when certifying, which is what makes the certificates carry weight.
For contracts above roughly £50k-£100k, professional administration typically saves its fee by preventing overpayment and controlling variations — and it removes you from direct confrontation with your builder. For smaller works we can set up the contract and provide light-touch administration at key stages.
The CA administers traditional contracts impartially between the parties; an employer’s agent acts solely for the client on design and build contracts. Which you need follows from your procurement route — we provide both and can advise which fits.
Under a properly administered JCT contract, you pay in arrears for work done, as valued and certified — large deposits are unnecessary and risky. If a contractor insists on substantial money up front, that is a warning sign worth discussing before you commit.
With an administered contract you have a documented position: certified payments, recorded progress and a termination procedure. We administer the termination correctly, quantify the cost to complete, and support recovery — a dramatically stronger position than an undocumented handshake arrangement.
