How we choose our partners

We only introduce you to local installers and suppliers we genuinely rate. Here’s exactly how we decide who makes the cut.

1

Independent Advice First

We give you clear, honest information using the Planning Passport and our guides before any introductions are made.

2

Personally Reviewed

Every enquiry is looked at by a real person with over 10 years’ experience before we decide who to connect you with.

3

Only Quality Local Partners

We only work with companies we genuinely rate and would recommend to family or friends in Devon and Cornwall.

Why this matters

It’s common in this industry to be passed between companies or given advice that’s influenced by sales targets. We take a different approach. We focus on giving you clear information first, and only connect you with local companies when you’re ready.

How we review every enquiry

Every submission is personally reviewed. We don’t use automated lead systems.

We check your project stage and property details

This helps us understand your situation and only connect you with suitable companies.

We only pass you to companies who cover your area

We don’t send your details to national companies or installers who don’t work in Devon and Cornwall.

We protect your information

Your details are only shared with the installers we introduce — then deleted. We don’t sell your data to marketing lists.

The companies we work with

We’re selective. Our name is attached to every introduction, so we only work with companies that meet our standards.

Proven track record

We only work with companies who have a good reputation for quality work and clear communication in the South West.

Relevant experience

We prioritise companies with strong experience in retrofit projects, older homes, and combining technologies like heat pumps with underfloor heating.

Capacity & responsiveness

We only introduce you to companies who currently have availability and respond properly to enquiries.

Transparency in our Planning Passport numbers

Our planning bands are designed to give realistic figures rather than optimistic ones.

  • We use current 2026 pricing for Devon and Cornwall
  • We factor in typical challenges with older and retrofit properties
  • We avoid over-promising on running cost savings
  • All figures are indicative installed prices

We prefer to give you numbers you can trust rather than numbers that sound too good to be true.

Our commitments to you

We only introduce companies we rate

If we wouldn’t recommend a company to family or friends, we won’t pass your details to them.

We personally review every enquiry

No automated systems. Every submission is reviewed by a real person before we decide who to connect you with.

We only work with companies who have capacity

We don’t send you to installers who are too busy to give your project proper attention.

There is never any pressure. You can use the Planning Passport and guides with no obligation to proceed.
