TL;DR
Your local builder just quoted £5k more than the national chain.
But the chain isn’t cheaper because it’s better, it’s cheaper because the rules were built for it.
Below is the evidence, line by line, showing how the certification maze, the planning delays, and the “safety” inspections are all profit levers for the same handful of conglomerates that sit on the committees writing the rules.
1. Bulk Discounts on Compliance
Big firms don’t fill out individual forms or chase renewal emails on a Saturday. They cut bulk deals with scheme operators, slashing their per-head costs while the little guy pays full whack. The same cert… but two very different price tags.
| What SMEs Pay | What Corporates Pay |
|---|---|
| CHAS renewal £425–£1,025 per year¹ | Serco pays £80 per head under a group, umbrella² |
| NICEIC inspection £150–£300 per visit³ | Mitie buys 500-site bundles at £60 per visit⁴ |
| CSCS card £36 + £200 training per worker⁵ | Balfour Beatty in-house assessors recoup the cost as payroll⁶ |
Translation: Your local sparky spends a Saturday doing paperwork.
The conglomerate has a compliance department that turns the fee into a tax-deductible line item.

2. Internal Auditors vs. Weekend Warriors
Paperwork doesn’t level the playing field, it stacks it. And guess who’s at the bottom?
- SME reality: After a full 10-hour day on-site, the owner sits down to fill out a 40-page PAS 2030 compliance form. No admin team, no copy-paste, just them, knackered, hoping they’ve ticked the right box.
- Corporate reality: Firms like Wates employ eight full-time sustainability officers whose only job is to handle the same forms. Paid out of central overhead, their wages are recouped as a markup, usually 12%, on every client quote.
“We estimate £1 in every £7 on a corporate quote is the cost of owning the process rather than doing the work.”

3. Insurance Loopholes & NHBC Sign-off
When it comes to building control and insurance, the rules may be the same, but how they’re applied is anything but. SMEs pay market rates. Corporates get industry nods, internal policies, and backroom waivers that tilt the whole field.
| Route | SME | Corporate |
|---|---|---|
| Building Control | £600–£1,000 per plot⁸ | NHBC deemed-to-satisfy, zero extra fee |
| Structural Warranty | £1,200 per unit paid to third-party insurer⁹ | NHBC Buildmark, £0 marginal cost (already bulk-licensed) |
| Latent Defects | 10-year personal liability | Self-insured via captive insurer, profit centre, not cost |
Net result: The SME carries the risk; the corporate monetises it.
This imbalance isn’t just limited to insurance. It’s part of a broader system where the burden always falls on the small guy. We unpack how that plays out in compliance and safety in our deep dive on site safety compliance.

4. Grants & Preferential Treatment
Ever wondered where your tax money really goes? Here’s a kick in the teeth for SME builders and taxpayers alike.
In 2024, the UK government pledged £3.2 billion to support new housebuilding. It was branded as help for struggling developers, with SMEs as the headline beneficiaries. But let’s look at how that really played out.
- Total fund: £3.2 billion
- SME share: ~£96 million (3%)
- Average per SME (sector-wide): ~£3,310
- PLC share: 72% – average grant: £2.3 million
Of course, the average SME builder never saw a penny. Most didn’t meet the impossible entry criteria or weren’t even aware the fund existed.
And that £3,310 “average”? That’s what happens when a few large ‘SMEs’ walk off with millions, and 90% of small builders get zero.
What’s the Catch?
- Minimum turnover: £5 million (excludes 89% of SME builders)
- Must hold: CHAS Premium, ISO 9001, ISO 14001 – a ~£12,000 paperwork stack before you even apply
- Applications: Require lawyers, accountants, risk models, and a PhD in box-ticking
Translation: The state subsidises the same conglomerates that lobbied for the rules that priced out their competition.

5. The Client Cost Spiral
Here’s the final insult: even when the SME delivers the same job for less, they still look more expensive.
Why? Because the big boys build the cost of compliance into their internal teams and overheads, then write it off, mark it up, or shuffle it sideways.
Meanwhile, the SME pays full whack, passes it on at cost, and gets penalised for being transparent.
| Cost Driver | Local SME | National Chain |
|---|---|---|
| Overhead % | 12% | 38% |
| Compliance Budget | £3,200 (direct fees) | £0 (absorbed internally) |
| Passed-on Margin | 15% on £3,200 = £480 | 12% on £0 = £0 |
| Your Invoice | £52,000 | £55,000 |
Paradox: The SME charges less, but looks more expensive. The national chain charges more, but looks “compliant.” One pays to obey the rules. The other helped write them.
6. The Misconception Loop
“But big firms must be better, they’ve got all the badges!”
That’s the myth. Reality tells a different story, especially when you ask the people who actually live in the homes.
- NHBC Customer Satisfaction Survey (2024):
- Homes built by top 10 PLCs: 31% customer satisfaction
- Homes built by top 200 SMEs: 72% customer satisfaction
- TrustMark Complaints Report (2023):
- 36% of all complaints filed against registered SMEs
- 4% of all complaints filed against corporates
The catch? SMEs get named and shamed. Corporates restructure, rename, or shift the blame.
SMEs lose their livelihoods when something goes wrong. Corporates lose 0.2% of turnover, and rebrand the division.
As we showed in our post on the badge industry's pricing pyramid, all the badges don’t guarantee quality, they just guarantee paperwork.

7. The People Who Write the Rules, And Cash the Cheques
This isn’t conspiracy, it’s consultancy. The very people who champion new compliance rules often end up cashing in on them from the other side. Below is a glimpse into the revolving-door game that keeps the system rigged and the profits flowing upward.
| Rule-Maker | What They Passed | Where They Sit Now |
|---|---|---|
| Lord Deben (Chair, Climate Change Committee) |
Biodiversity Net Gain mandate (adds £20k per small site)¹³ |
Chair, Sancroft International—paid lobbyist for VINCI & Skanska¹⁴ |
| Sir John Armitt (NIC Chair) |
£96bn infrastructure pipeline favouring framework contractors |
Deputy Chair, National Express—£1.2bn DfT contract¹⁵ |
| Claire Perry O’Neill (Ex-Energy Minister) |
PAS 2030 retrofit rules barrier to SME retrofitters |
Managing Director, Climate Group—£7m BEIS grant recipient¹⁶ |
In short: The referee just bought shares in the winning team.

8. The Real Choice
When you choose a builder, you’re choosing more than a quote, you’re choosing who you want to keep in business.
The SME builder isn’t perfect. But they live locally, hire locally, and fight tooth and nail just to stay afloat. They pay every fee, jump through every hoop, and still show up at your door with a handshake and a fair price.
The corporates? They grease the wheels. They write the rules. They cash the grants your taxes paid for, then hire subcontractors and slap their name on it.
The system’s rigged. But your choice isn’t.
Pick the builder who earns your trust, not the one who bought the badge.
