A plain-English written contract between a homeowner (or small business) and a builder / tradesperson, generated from the user's own description of the job and signed online by both parties. The strongest single candidate from the casual-contracts cluster — score 30, Rob's clearest brand-fit on the Sorted side, and the cleanest expression of his "intent-to-create-legal-relations" thesis from the 19 May meeting. The promise. "Both sides know what was agreed. Both sides signed it. If it goes wrong, you have something in writing."

BCustomer input — what we ask the user

B.1The conversation shape

Chat-style guided interview, ~6–10 minutes to complete. Plain English throughout — no legal jargon in the prompts. Save-and-resume from any device. The tone is "what did you actually agree?" rather than "complete this legal form." The interview adapts based on whether the user is the homeowner side (most common entry point) or the builder side (the membership-tier user) — same output document, slightly different framing.

B.2The fields we collect

Section A — Who's involved

Section B — The job

Section C — Money

Section D — Quality and variations

Section E — When it goes wrong

Section F — Sign-off

B.3Evidence & verification

B.4Branching & edge cases

  1. Homeowner ↔ builder, fixed price, single job — the simplest path; default flow.
  2. Homeowner ↔ tradesperson, day rate, open-ended — pivots to estimated days, daily cap, weekly review.
  3. Small business ↔ contractor — adds VAT registration fields, business vs trading address.
  4. Builder-initiated — builder is the user, generating the contract to send to their homeowner client.
  5. Variation to an existing arrangement — handles backdated start and explicit acknowledgement clause.

B.5Drop-off risks

CProduct output — what the customer receives

C.1The deliverable

A 3–5 page plain-English agreement plus a one-page summary cover note. Two formats: PDF (signed) and DOCX (editable before signing). Delivered through an in-product e-sign envelope (DocuSign-equivalent flow on our own infrastructure) and emailed to both parties on completion.

Branded throughout per brand/brand-book.md:

ECompliance guardrails

E.1Why this is 🟢

Building contracts between private parties are not reserved instruments under LSA 2007 Sch.2. The product does not provide legal advice on whether the contract is enforceable in a specific dispute, does not represent either party, and does not file or submit anything to any tribunal. The user supplies the terms; we render those terms as a contract document; the user reviews and signs in their own name. This is squarely inside the self-help template framing and outside both the LSA reserved-activities perimeter and the FCA claims-management regime. Per regulatory-stance v3, the casual-contracts cluster is the cleanest opening front.

E.2User-as-actor framing

  2. "Verbal agreements with builders: what does the law actually say?" Research / high-conversion. Answers the "is a handshake binding" question.

Each article ends with a soft CTA — "Want your job in writing? Try our free builder contract." — never a hard sell. All copy compliance-reviewed before publication.

F.6Off-page / amplification

Rob fit. Strong. Rob's instinct from the bench (per meeting-notes-2026-05-19 §1) is that intent-to-create-legal-relations is the backdrop to most low-level consumer disputes — and the Builder Mock-Up Contract is the cleanest expression of that thesis.

Editorial line (draft): "Most of the cases I saw on Judge Rinder came down to one thing — nothing was ever written down. This fixes that." — Rob Rinder, co-founder.

Charity partner fit. Citizens Advice (homeowner side — "got a builder you're worried about?" referrals); Federation of Small Businesses (small biz commissioning fit-outs); Age UK (elderly homeowner protection from rogue traders); HomeOwners Alliance (natural editorial overlap).

MSE / Which? fit. Excellent. MSE has long-running coverage of cowboy builder issues; "free builder contract template" slots into their existing reader-resources angle. Which? has a Trusted Traders product — there's a partnership conversation rather than a competitive one.

PR angle. The data story is the headline: "Eight out of ten UK building disputes involve no written contract" (we'd need to source-check this stat or commission research). The product-driven angle: "Rob Rinder launches free builder contract after years of seeing handshake-deal disputes destroy homes." Tabloid-friendly, fits Rob's existing public profile.

Affiliate / partner channels.

F.7The marketing "do not say" list — product-specific additions

GBuild dependencies & open questions

G.1What we need before launch

G.2Open questions

  1. Free vs freemium structure. First contract free with paid subscription for repeat use, or everything free with paid premium features (storage, dispute pack, witnessed signing)? Affects the funnel and the marketing line.
  2. Builder side or homeowner side first? Both are legitimate users but need slightly different onboarding flows. Do we ship one and iterate, or both at v1?
  3. Variation-Order Tool — separate product or built into this one? Listed as Product #2 (score 29) in the Risk Register, but operationally it might be cleaner as a feature of this product rather than a standalone. Affects the count of the 12 and the cross-sell logic.
  4. Statutory interest framing. Late Payment of Commercial Debts (Interest) Act applies for B2B; for B2C the basis is different. The contract needs to handle both shapes cleanly without giving legal advice on which applies.
  5. Trade-association partnership conversations. Worth having pre-launch (creates a soft-launch channel) or post-launch (we have proof points)?

1.Parties and the job

This agreement is made between the parties named below in connection with the job described in clause 2.

Homeowner Sarah Whitmore and James Whitmore 24 Oak Street, Bromley BR1 2NN

Contractor Hayward Construction Ltd trading as Hayward & Sons Builders
Unit 7, Birch Industrial Park, Sevenoaks TN13 1PE

The job in one paragraph. Construction of a single-storey rear kitchen extension at 24 Oak Street, Bromley, including supply and fit of structural steel, brickwork to match the existing rear elevation, two skylights, a 4-metre bi-fold door, internal plastering and decoration to a paint-ready finish, and re-tiling of the existing kitchen floor to extend into the new space.

2.The works

2.1What's being done

A single-storey rear extension of approximately 18 m², adjoining the existing kitchen at the rear of the property. The works include: foundation excavation and pour; cavity-wall construction to match the existing rear elevation in stock brick; a flat roof with two 1200 × 800mm skylights; a 4-metre aluminium bi-fold door to the garden elevation in anthracite grey; full internal plastering to a paint-ready finish; first-fix and second-fix electrics including six downlights, two pendants, and four double sockets to current Part P standards; re-tiling of the existing 12 m² kitchen floor with new porcelain tiles (homeowner-supplied) to flow continuously into the new space; and removal and disposal of all construction waste.

2.2Where

All works take place at 24 Oak Street, Bromley BR1 2NN. The contractor has visited the site on 8 May 2026 and is satisfied with site access via the side passage.

2.3Materials and who supplies them

  • Contractor supplies all structural materials, brickwork, mortar, plasterboard, plaster, skylights, the bi-fold door, electrical wiring and fittings, sand, cement, aggregates, fixings, and all consumables.
  • Homeowner supplies the floor tiles (already purchased — Mandarin Stone "Bramley" porcelain, 60 × 60cm, 32 m²), the kitchen paint (two coats, colour to be agreed), and the final socket faceplates if the homeowner prefers a non-standard finish.

2.4Quality standard

Workmanship to FMB trade standard. Electrical work to BS 7671 (current edition) and certified under Part P. Brickwork to match existing in colour, bond and mortar joint. Plastering to a paint-ready finish (no visible trowel marks under standard household lighting at 1 metre).

"Trade standard" means the quality a normal professional builder would produce. If you think something falls short, the snagging process in clause 6.4 is how you raise it.

3.Timeline

3.1Start date

Monday 15 June 2026. The contractor will be on site from 8:00am.

3.2Target completion date

Saturday 12 September 2026. This allows approximately 13 weeks for the works described in clause 2.

3.3Allowance for delays outside the contractor's control

The target completion date may be extended for delays caused by: exceptional weather (sustained rain or sub-zero temperatures preventing safe outdoor work); supply chain failure beyond the contractor's reasonable control (specifically: a delay in delivery of the bi-fold door from the manufacturer); or variations agreed under clause 4. Any extension claimed under this clause must be notified to the homeowner in writing within 5 working days of the cause arising.

4.Price and payment

4.1Total price

£42,500.00 plus VAT at 20% — a total of £51,000.00 inclusive. This is a fixed price for the works described in clause 2. Variations under clause 5 are priced separately.

4.2VAT treatment

The contractor is VAT registered (VAT no. GB 248 5571 03). VAT is added at the prevailing standard rate on the dates payment becomes due.

4.3Deposit

A deposit of £8,500.00 inclusive of VAT is payable on signing of this agreement, to cover initial materials orders (notably the bi-fold door and skylights, both of which require 6-week lead times). The deposit is non-refundable once materials have been ordered, save for the contractor's failure to start the work on the date in clause 3.1.

4.4Payment schedule

The remainder is paid on completion of milestones, each of which must be agreed in writing by both parties before the corresponding payment falls due:

MilestoneTriggerAmount (inc. VAT)
DepositOn signing of this agreement£8,500.00
Foundations completeSlab poured, cured, and signed off by both parties£10,000.00
Watertight shellWalls up, roof on, bi-fold door installed, building weather-tight£15,000.00
Second fix completePlastering, electrics and tiling complete, Part P certificate issued£12,500.00
Final completionSnagging list cleared, site cleaned, all certificates handed over£5,000.00
Total£51,000.00

4.5Late payment

Where the homeowner is a private consumer, statutory interest may apply to late payments under the relevant late-payment legislation. The parties agree to first attempt to resolve any payment dispute through direct discussion under clause 7.

If a payment is properly due and not paid within a reasonable period, the law allows the unpaid party to claim interest. The exact rate depends on whether this is a business-to-consumer or business-to-business contract. Both sides should raise problems early.

5.Variations

5.1How variations are proposed and agreed

A variation is any change to the works described in clause 2 — whether that means adding work, removing work, changing materials, or changing the specification. Either party may propose a variation in writing (email is acceptable). No variation is binding until both parties have signed and dated a written record of it.

5.2How variations are priced

The contractor will provide a written breakdown of the price impact of any proposed variation — additional materials cost, additional labour days, and any impact on the timeline in clause 3 — within 3 working days of the variation being proposed. The homeowner may accept the variation, reject it, or counter-propose. The works otherwise continue under the original terms.

5.3Variations must be in writing

The parties acknowledge that verbal agreements to vary the works are a common source of dispute. The parties agree that no variation is binding unless recorded in writing and signed by both parties. The contractor recommends using the LegalHelp Variation-Order Tool for this purpose; any clear written record signed by both parties is sufficient.

6.Insurance and responsibilities

6.1Public liability insurance

The contractor confirms it holds public liability insurance with a limit of indemnity of at least £5 million for any one occurrence. A copy of the certificate has been provided to the homeowner and is dated 4 April 2026, valid until 3 April 2027.

6.2Employer's liability

The contractor confirms it holds employer's liability insurance covering all of its employees and operatives who will be working on the site, with a limit of indemnity of at least £10 million. Certificate provided 4 April 2026.

6.3Workmanship

The contractor warrants its workmanship for 12 months from final completion. Defects in workmanship notified in writing during this period will be rectified by the contractor at no charge. This warranty is in addition to any rights the homeowner has under consumer law.

6.4Snagging

On the day of final completion, the parties will walk the site together and produce a written snagging list of any items requiring further work. The contractor will rectify all snagging items within 21 days, or such longer period as the parties agree in writing. The final payment in clause 4.4 is held back pending snagging clearance.

7.Termination

7.1By agreement

The parties may at any time agree in writing to terminate this contract. Payment for work properly done up to the date of termination is calculated proportionately against the payment schedule in clause 4.4.

7.2For unfixed default — 14 days' written notice

Either party may terminate this contract by 14 days' written notice where the other party is in material breach of its obligations and has failed to remedy that breach within 14 days of being notified of it. Material breaches include, but are not limited to: the contractor failing to attend the site for 10 consecutive working days without prior notice; the homeowner failing to make a payment that has properly become due under clause 4.4; or either party becoming insolvent.

7.3Payment on termination

On any termination, the contractor is entitled to be paid for work properly done and materials reasonably ordered up to the date of termination, less any sums already received. Where the homeowner terminates for the contractor's default, the homeowner may also deduct the reasonable cost of having another contractor complete the works to the original specification.

Termination is a last resort. The notice period gives the party in breach a fair chance to fix the problem before the contract ends. Always raise issues early and in writing.

8.Dispute resolution

8.1Direct discussion first

If a dispute arises between the parties, they will first attempt to resolve it by direct discussion within 14 days of the issue being raised in writing. Both parties will set aside time to meet (in person or by video call) and to consider the other side's position in good faith.

8.2Mediation

If direct discussion does not resolve the dispute, the parties will attempt mediation through a recognised mediation provider (such as the Centre for Effective Dispute Resolution, or a mediator suggested by the Federation of Master Builders' dispute resolution service). The cost of mediation is shared equally unless the parties agree otherwise.

8.3Small claims court

If the dispute is not resolved by mediation, either party may bring a claim in the County Court of England and Wales. Claims of £10,000 or less are dealt with through the small claims track. The parties acknowledge that the courts of England and Wales have exclusive jurisdiction over disputes arising under this contract.

Going to court is rarely the best outcome for either side. The earlier stages — talking and mediation — resolve the great majority of building disputes faster and at lower cost.

9.General

9.1Entire agreement

This contract — together with any written variations signed under clause 5 — is the entire agreement between the parties about the works. It replaces any earlier verbal or written discussions, quotations, or proposals.

9.2Notices

Any written notice required under this contract is given by email to the addresses in clause 1, or by letter sent by first-class post to the postal addresses in clause 1. Notices by email are deemed received the next working day; notices by post are deemed received the second working day after posting.

9.3Severability

If any clause of this contract is found to be unenforceable, the rest of the contract continues in full force.

9.4Counterparts

This contract may be signed in counterparts (one part by each party). Electronic signatures are accepted, including via the LegalHelp e-signature envelope used to produce this document.

9.5Governing law

This contract is governed by the laws of England and Wales.

What happens next. Both parties receive a signed PDF by email immediately. The contract is stored in your LegalHelp account if you have one (and unlocked unlimited if you take out a membership). At 4 weeks we'll check in to ask if any variations need logging. At final completion we'll send a snagging template.

If something goes wrong — first talk it through (clause 8.1), then try mediation (clause 8.2), then small claims (clause 8.3). Most disputes are resolved at stage 1.
