Frequently Asked Questions

We are independent of manufacturers and are not part of a commercial installer scheme, referral network or installer-benefit network. Our advice is impartial: we assess equipment and system options on technical merit, suitability for your site and overall cost. Our professional registrations and consumer-protection memberships are separate from this. This means:

• We'll recommend the most appropriate technology for your application, not what a manufacturer wants to sell
• We source from multiple suppliers to get the best value and lead times
• Our designs aren't constrained by proprietary system limitations
• We can work with your preferred equipment where technically viable

Yes. We work on homes, commercial premises, farms, institutional projects and wider sites. The scope can cover an individual building or energy and electrical systems across a site, including generation, storage, heating, controls and supply constraints. Tell us about the site and what you need; we will confirm whether we are the right fit.

We operate across the UK. For installations, we typically work within a reasonable travel distance but will consider projects nationally depending on complexity and duration. Remote consulting and design work is available anywhere.

The Boiler Upgrade Scheme (BUS) supports eligible low-carbon heating installations in England and Wales. Grant amounts checked 4 November 2026:

• £7,500 towards an eligible air-to-water or ground source heat pump, including water source.
• £9,000 total for eligible air-to-water or ground source heat pumps under the temporary uplift through 31 March 2027. The property must be heated by oil or LPG and have no mains gas connection.
• £2,500 towards an eligible air-to-air heat pump. Check the separate property and heating requirements and the Ofgem product eligibility list.
• £5,000 towards an eligible biomass boiler in a rural property off the gas grid.

How to apply. An installer certified under MCS for the relevant technology applies on the property owner’s behalf. The installer checks the property, existing heating and proposed system against the scheme rules, then shows the grant deduction in the quote and invoice. Ask which work is included and what you will pay. See the current BUS guidance.

VAT. Qualifying installations of energy-saving materials, including eligible heat pumps in residential accommodation in Great Britain, can be zero-rated through 31 March 2027 under current rules. VAT depends on the supply and the premises. Check the treatment of your installation and any associated work in the quote. See HMRC VAT Notice 708/6.

MCS (Microgeneration Certification Scheme) covers defined types of installation. We provide MCS certification only for eligible installations within our registered scope; it does not apply automatically to every service or project we undertake.

For work outside that scope, the proposal sets out the applicable standards and certification. We confirm any project-specific grant or export-scheme certification requirements before proceeding.

This is one of the most common challenges we encounter. We have several strategies:

• Load management: Smart systems that distribute available power dynamically across multiple loads (chargers, HVAC, etc.)
• Phased approach: Install what you can now, design for future expansion when supply is upgraded
• Energy storage: Batteries that charge during off-peak and supply during peak, reducing maximum demand
• DNO engagement: We handle applications for supply upgrades, which can sometimes be achieved with minimal infrastructure work

Yes. We offer comprehensive maintenance packages that include regular inspections, performance monitoring, and responsive repair. We also provide remote monitoring for systems we install, with alerts for faults or performance degradation. See our maintenance services page for details.

We provide detailed quotes after an initial site survey and requirements discussion. Our quotes include:

• Technical specification of all equipment and works
• Itemised pricing
• Installation programme
• Performance projections with assumptions clearly stated
• Warranty and aftercare details

We don't do vague estimates. You'll know exactly what you're getting and what it costs before we start.

Not every project needs to have a financial payback. Some projects are driven by:

• Regulatory compliance (MEES, building regulations)
• Corporate social responsibility commitments
• Energy security and resilience (backup power, grid independence)
• Tenant requirements or lease obligations
• Strategic positioning for future regulation

We'll give you an honest assessment of whether a project makes financial sense, but we also help you understand the broader value proposition when the payback isn't straightforward.

Yes — this is actually a significant part of our business. We regularly undertake:

• Assessment and rectification: Surveying poorly designed or installed systems and providing remediation plans
• Performance optimisation: Getting better performance from existing systems that aren't delivering as expected
• Expert witness: Providing technical assessments for disputes, insurance claims, or regulatory matters
• ECO4 remediation: Addressing issues with poorly installed government-subsidized measures

If you've had a bad experience with a previous installer, we'll give you an honest assessment of what's wrong and what it would take to fix it. No sugar-coating, no blame-shaming — just practical engineering advice.

• Public Liability: £5,000,000 any one claim, unlimited in the period of insurance
• Employers' Liability: £10,000,000 any one claim
• Professional Indemnity: £500,000 each and every claim and in the aggregate
• Goods in transit and tools: £2,500

Employers' and public liability are underwritten by Admiral Insurance (Gibraltar) Ltd, arranged through Kingsbridge; professional indemnity by AXA XL Insurance Company UK Ltd. Contract works and plant are not covered under our policy — where a project needs them, we arrange cover specifically. Policy schedules are published on our Partners & Insurance page; certificates available on request.

We take complaints seriously. Our process is:

1. Contact us directly — most issues can be resolved quickly through direct discussion
2. If unresolved, our formal complaints procedure kicks in with a nominated Complaints Handler
3. For domestic customers, if we can't reach a resolution, HIES (the Home Insulation and Energy Systems Quality Assured Contractors Scheme) provides independent adjudication

We're TrustMark registered, which requires us to have robust complaints procedures. We'd rather resolve things directly than escalate, but the option is there.
