Since our initial conversation we've completed a full strategy foundation for the Batterybox launch:
| Document | What it contains |
|---|---|
| research-synthesis.md | Who the customers are, what problems we're solving, opportunity areas prioritised |
| competitive-analysis.md | What's currently in the UK market, pricing benchmarks, where Batterybox sits |
| brand-voice.md | How Batterybox should sound — grounded in Bow Tie's existing voice and website |
| feature-spec.md | What the product is at launch — configurations, pricing assumptions, success metrics |
Everything is grounded in your transcript conversation and cross-checked against the UK market. Where we didn't have confirmed information, we've made working assumptions — all of which are flagged below for your sign-off.
The market position is clear. No purpose-built, aesthetically considered, brand-agnostic external enclosure exists for the UK retrofit residential market. The closest competitor on protection (Eco-ESS) is trade-only, quote-only, and entirely utilitarian. The closest on aesthetics (Battery Covers Ltd) is a cover, not an enclosure. Batterybox owns the gap between them.
Pricing assumptions hold up. Working assumptions of £699 (founding partner trade) and £899 (standard trade) undercut the best current installer fallback — GRP cabinets at £819–£980 — while delivering a purpose-built product. End-customer RRP of £1,200–1,400 is credible against bespoke metalwork starting at £1,000+.
The regulatory wind is behind you. PAS 63100:2024 (March 2024 fire safety standard) is disqualifying improvised solutions and pushing installers toward documented, compliant products. Batterybox is compliant by design.
GivEnergy is the primary target. At ~35% UK market share, GivEnergy batteries are not fully outdoor-rated — making them the largest single segment that needs an enclosure. Growatt, Fox ESS, SolarEdge, and Alpha ESS are secondary targets.
The benefit hierarchy (from your transcript, in order):
- Access and ease of servicing — no loft ladders, no entering occupied properties
- Space — no garage, no wall, no problem
- Battery and inverter together in one place
- Equipment longevity — thermal management extends lifespan
- Safety — fault isolated outside the building
- Security — lockable, tamper-proof
Brand: Batterybox launches as a sub-brand of Bow Tie Construction, inheriting 10+ years of retrofit credibility, awards, and trust. Same voice, same standards, natural extension of the Ventbox product line.
These are the six things blocking the next phase. Nothing can be finalised — roadmap, sell sheet, website copy, outreach — until these are answered.
We've assumed £400–500 per unit at a 20-unit minimum from your Polish manufacturer. This is the foundation of the entire pricing structure.
- Exact cost per unit at 20 units
- Cost per unit at 50 units (for the standard trade price tier)
- Confirmed lead time (we've assumed 4 weeks)
We've assumed three standard configurations:
| Config | Battery size | Ventilation |
|---|---|---|
| Standard | 5–7 kWh | Natural |
| Standard+ | 10–12 kWh | Fan-assisted |
| Premium | 10–12 kWh | MVHR connection |
- Is this the right split?
- Is the MVHR configuration ready for v1 launch, or should it be v2?
- Does one box size fit all batteries, or are there different external dimensions per config?
- Which specific battery models have you confirmed fit? (We've assumed GivEnergy 9.5kWh + common hybrid inverters as the primary target)
We've assumed two colour options at launch: Cream and Off-White.
- Can the manufacturer support two colours at a 20-unit minimum run?
- Are there specific RAL codes or colour specs already agreed?
We've assumed Batterybox launches as a sub-brand of Bow Tie Construction Ltd — not as a new legal entity. This is the faster, lower-friction route and lets the product borrow Bow Tie's credibility from day one.
- Is this correct, or does it need to be a separate entity for equity/partnership reasons?
- What is Blue Electrics' commercial role — revenue share partner, or installation-only partner?
- Has anyone checked domain availability? (batterybox.co.uk, batterybox.bowtie.co.uk)
In your transcript you said a Batterybox installation is "probably also a very good solution" from an insurance perspective. This is a strong homeowner argument — but we can't use it as a headline until it's confirmed.
- Has anyone spoken to a home insurance broker or underwriter about this?
- If yes, what did they say?
- If no, is it worth a quick call to confirm before we put it in writing?
Every marketing asset — sell sheet, website, brochure, LinkedIn post — is significantly weaker without visuals.
- Has a 3D render been commissioned? If yes, who and when? If no, we should commission one immediately (est. £300–600 from a product visualiser).
- When is the first Batterybox install expected? This sets the date for professional photography.
- What's the budget available for render + first photography shoot?
- Is the prototype in good enough condition to film a 60–90 second walkthrough video now?
Once we have your answers, the next steps move fast:
- Finalise pricing and configurations
- Commission 3D render if not already done
- Register domain
- Write and design the one-page B2B sell sheet
- Write website copy (holding page first, full product page to follow)
- Begin personal outreach to warm installer contacts
- Secure 5–10 founding partner commitments
- Work toward 20-unit production run order
- A4/A5 homeowner brochure
- 60–90 second product video
- LinkedIn launch posts
- Full product page live on bowtieconstruction.co.uk
The product page, brochure, and video can all be built in parallel with the outreach — they don't need to exist before conversations start. A sell sheet and a personal message is enough to begin.
The product sells itself once someone understands it. The job right now is getting it in front of the right people as fast as possible. Everything in this plan is in service of that.
