CLIENTS ONLY — SO EVERY ENGAGEMENT GETS PROPER ATTENTION

You bid like a pro.
You administer like an amateur.

It's not your fault. The tools were built for Tier-1 contractors. You've never had access to a QS in your corner the way the people across the table from you do. 4–7% of contract value silently disappears in admin failures — missed notices, untracked variations, short-payments without challenge, weak final accounts. That's the cost of going alone.

A retainer QS sits on your side from kick-off through final account. Same commercial discipline as a Tier-1 has. Without the Tier-1 cost structure.

"For fifteen years I sat on the main contractor side, watching the same subbies miss the same notices, accept the same short-payments, and lose money they were absolutely entitled to. They weren't bad operators. They were drowning in admin built for someone else. Now I'm on the other side of the table — yours."

— Tom Speller, founder & lead QS

TS
Founder & Lead QS

"I spent fifteen years administering JCT and NEC4 sub-contracts from the main contractor and developer side. I issued the pay-less notices, the contra-charges, the late information that became your EOT claim. Now I'm on the other side. I built this so every UK subbie can have what I had — a QS who sees the whole game."

First five clients are special.

Founding members get locked-in pricing for 18 months, monthly product roadmap calls, and direct say in what the upcoming SubbieHQ platform does first.

Recovered £14k on a final account I'd written off, three months after I started with Tom. He saw what I'd missed.

For the first time in five years I know what every job is worth in real time. The weekly review call is the thing I look forward to most.

What subbies ask us first.

How is this different from hiring a freelance QS?

Freelance QSs charge £400–£600/day. Most subbies use them reactively — when something has already gone wrong. The retainer model is different: I'm working WITH you continuously, catching things early, keeping the admin running properly. The £495/mo entry tier costs less than a single day of freelance work and gives you cover all month.

Do I have to commit to a long contract?

No. All tiers are monthly. Cancel any time with 30 days' notice. The intent is to earn your retainer every single month, not lock you in with a contract.

What if you can't take me on?

I cap the practice at 5 retainer clients so each one gets proper attention. If I'm full, the strategy call is still free and useful — I'll either put you on a wait list or recommend a colleague better-fit for your situation.

What forms of contract do you cover?

JCT family (SBCSub, ICSub, DBSub), NEC4 Sub-Contract, and bespoke main-contractor amendments. Every contract you're considering or have signed gets reviewed against the unamended standard so you know exactly what's been changed.

Will my main contractor know I'm using you?

Only if you tell them. All notices, letters, applications and submissions go out on your letterhead — never branded as us. From the main contractor's side, your commercial admin just suddenly got tighter.

How quickly can I start?

Strategy call within 5 working days. Onboarding starts the same week you sign up. First commercial review call within 7 days. Notices drafted from week one.

What's coming with the upcoming SubbieHQ platform?

A live, cloud-based version of the workbook toolkit with auto-populated calendars, contract scanner, change log, payment notice tracker, and forecast final account dashboard — all driven by your live data. Retainer clients get founding-member access free for the first 12 months of release.

I'm not sure I'm ready for a retainer — can I just buy templates?

Yes — start with the free Payment Application Tracker. If you upgrade to the £149 bundle you get a free 30-minute health check call included. Many founding-member retainer clients started by buying a workbook first.

Stop running the commercial side on instinct.

First strategy call is free. 30 minutes. Zero commitment. I'll tell you straight what I'd fix first — whether you sign up or not.
