01 — About
About Sustec.
Sustec is the group brand. Its role is to support, connect and future-proof a portfolio of operating businesses, while allowing those businesses to retain their own market identity and specialist positioning.
Sustec (Sustainable Technologies Limited) was created in 2025 through the management buy-out of Aqualogic by Ben Rice and Ashley Williams. It is the platform behind a deliberate buy-and-build strategy across water services, technical services, consultancy, repair and maintenance, wastewater services and adjacent sustainability markets.
Sustec is not a customer-facing operating brand. It does not deliver services directly. Its role is to set the architecture, support shared infrastructure (governance, finance, group leadership), enable group-level growth, and create credibility behind each operating business without overshadowing it.
- We don’t follow the transition to sustainable technologies. We help shape it.
- We help strong organisations become stronger.
- A collaborative model designed for impact — quietly building scale, resilience and long-term capability.
- Founded by experienced industry operators.

04 — Group strategy
Group strategy.
Sustec is the platform for a deliberate buy-and-build strategy, focused on building a high-quality group with annual turnover exceeding £50m through the acquisition of three to five complementary SMEs across water and adjacent sectors.
The approach is targeted and disciplined: identifying strong, well-run organisations with established reputations, and integrating them into a cohesive group that enhances overall capability, resilience, and market reach.
At its core, the strategy is about strengthening what already works: providing the structure, capital, and strategic direction to enable each business to scale, collaborate, and deliver greater collective value within a unified platform.
Strategic intent
- Identify and engage complementary organisations.
- Acquire three to five complementary SMEs.
- Target a group annual turnover greater than £50m.
- Expand group services for added value.
- Diversify across sectors for risk mitigation.
- Maximise group cross-selling opportunities.
- Create a strategic circular economy.
Market context (AMP8)
The UK water sector has entered an unprecedented era of investment with PR24 (2025–2030): around £104bn approved, nearly double the previous AMP. Focus areas include drought resilience, sewage spill reduction, smart metering expansion, leakage detection and pressure management. This scale of investment creates space for complementary acquisitions across water services, wastewater, repair and maintenance, and adjacent renewables markets.
05 — Brand architecture
Brand architecture.
Sustec is the group brand. Its role is to support, connect and future-proof a portfolio of operating businesses, while allowing those businesses to retain their own market identity and specialist positioning.
How it works in practice
Operating brands lead with their own stories, voice and customer-facing language. Sustec provides the group endorsement, the portfolio context and the platform behind them. The Aqualogic website should point up to Sustec as its parent; the Sustec website should point down to operating companies.
Endorsement wording
Where Sustec is referenced on operating-brand collateral, use a light endorsement:
Aqualogic, a Sustec company
Where Aqualogic is referenced on Sustec collateral:
Aqualogic is a Sustec company specialising in integrated water conservation and demand management.
06 — Heritage
Heritage.
Sustec is new, but the businesses it supports are not. The group draws on decades of operational experience inside Aqualogic and brings that experience together under a structure built to scale.

Flow Control
Originally a company called Flow Control, started by Mike Rice. Roots in practical water conservation and operational delivery.
2004
Aqualogic is born
Aqualogic was born out of a partial acquisition of Flow Control. Ben Rice appointed Managing Director.
2014
Major framework wins

2020
Digital and customer expansion
Continued growth in Field Services and client services across UK water. Introduction of Virtual Water Audits and Digital Leakage detection.
2025
MBO and Sustec
Aqualogic crosses 250 employees. Ben Rice and Ashley Williams complete a management buy-out through a new holding company, Sustec Ltd (Sustainable Technologies Limited).
07 — Visual identity
Visual identity.
The Sustec brand uses a quieter, more architectural visual language than its operating companies. The shared typeface (Manrope) keeps the group feeling like a single system while colour and logo carry the distinct brand identities.
Logo
The Sustec lockup is used across group communications, the parent site, and as a supporting endorsement on operating-brand assets.
