About us
Clear answers from a small British team
Home Power Advisor is run by a small British business based in the Cotswolds. We help people bring their electricity bills down and keep the lights on when the grid can’t, by giving them clear, honest information and leaving the decision to them.
Who we are
Home Power Advisors is a small, dedicated team with a decade of experience working with on-grid and off-grid solar and battery systems. We know how these systems behave in real homes, not just on the spec sheet: what they cost, what they save, and what they can and can’t do when the power goes off.
We set up this site because the questions we hear most are simple ones, and the answers are often buried under sales talk. Will solar pay for itself? What size battery do I need? What happens in a power cut? We think you deserve straight answers to those, in plain English.
Why we started
Electricity has become one of the biggest bills in most households, and more people are wondering what they would do if the power went off for a few hours, or a few days. Neither worry has a one-size-fits-all answer.
Some homes save hundreds of pounds a year with a modest set of panels. Others are better off with a battery charged on a cheap overnight tariff, or simply a portable power unit for the fridge and broadband. Our aim is to help you find the option that fits your home, your budget and the way you live.
How we work
We don’t sell, we explain
We don’t sell solar panels or batteries on this website, and nobody will pass your details to a salesperson. Our job is to set out the options, the real prices and the sums, then step back so you can decide.
Our calculators show their working
Every rate and assumption is on the page, and you can change any of them to match your own bills and quotes.
Try the ROI calculatorOur system finder treats every brand the same
Products are ranked by the same rules: closest fit to what you need, lowest price, and best value per kWh of storage.
Start the finderWe show what prices include, and when we checked them
Prices change often, so we date them and tell you what is and isn’t covered, such as installation.
See battery pricesHow we’re funded
Some of the links on our site go to suppliers who may pay us a small referral fee if you buy from them. That never decides what we recommend. Our tools rank products by the same rules whether we earn anything from them or not, and our reviews say what we really think.
Your reasons
Different people, different reasons
Not everyone wants the same thing from solar and batteries, and that’s fine. Most people we talk to fall into one of three camps, or somewhere in between.
The best return
You want the numbers to stack up. Our ROI calculator compares solar with leaving the money in savings, investing it, or borrowing to pay for it, so you can see whether it really is the better use of your money.
Work out your returnPeace of mind
You’re happy to pay a little more so the heating, fridge, freezer and broadband keep going when the grid fails. For you, a battery with automatic switchover is less about payback and more about not having to worry.
Power-cut protectionYour own insurance policy
For some people, relying less on the grid and on energy companies is a form of protection against the rare but serious scenario: a long outage, a price shock, or simply wanting to be in control. Off-grid and backup systems are built for exactly that.
How off-grid worksNone of these is the wrong answer. We’ll help you see what each choice costs, what it gets you, and where the trade-offs are.
A little greener, too
Every unit your panels make is one you don’t have to buy from the grid, and over time a home system can cut a household’s carbon footprint. We see that as a welcome bonus rather than the main event, and we’ll leave how much it matters to you.
