Our Fair Pricing Policy

We operate a fair pricing policy because we like to be open and upfront.

Prices Quoted In Advance

All our prices are quoted and agreed in advance before we do any work so there’s no nasty surprises, only pleasant ones.

Phone Quotes

For most common heating, plumbing and gas work we can quote over the phone. We let you know the price when you call or if a site visit is required.

Out Of Hours

Whilst we are available 24/7, you can expect to pay more if you want us to come out of hours, like in the middle of the night or bank holidays.

Diagnosis Fee

Sometimes we have to do a diagnosis to discover what is faulty or where a leak might be coming from, and we charge by the hour for this. This is included in our minimum charge which is a 1 Hour charge and includes looking over the equipment or situation to assess the situation.

Multiple Faults

Sometimes, there may be more than one problem to fix and until the first problem we find is fixed we don’t know the existence of a second or third (or fourth) problem.

Most of the time we can foresee this and we let you know if we suspect this to be the case.

Minimum Call Out Fee

Our minimum call out fee is £79.00 +VAT

Boiler Service Fees

Our boiler servicing package cost between £48.50 to £180.00 +VAT, depending on make, model and type of boilers (gas, fire or water heater).

Large Projects

For larger projects we give free site visits quotes and/or estimates.

Cancellation Fees

If you do book us for a call out and you aren’t there when we arrive then we charge a cancellation fee.

If someone at your home falls ill or has COVID symptoms (namely cough or fever), then you need to let us know ASAP, to cancel the visit and avoid a cancellation fee.

Our cancellation fee is £39.50 + VAT.

Out of hours cancellation fee is £79.00 +VAT.

I used AHP to do my annual Landlord’s gas safety certificate. Tony was punctual, efficient and a very pleasant person. If there were any little issues, he resolved them quickly (this year, bleeding the radiators, last year sorting out a minor issue about the flue). Highly recommended.
Kate Sawyer

I was impressed with the professionalism of Tony.
Deirdre Taylor

Tony also serviced and mended my old boiler (old in 1990) until parts were impossible to find, always fast, accurate, and successful in keeping it going until 2013. I was most impressed when he also rang the gas board because of poor pressure and made sure that they would come out ans fix things too (I got a new meter).
